Two Bit da Vinci Pretty much spot on. But did you mention that the rear motor can be used in waste heat mode to heat up the car really well, especially start ups for the days beside software preconditioning/predictions.
One tiny little quibble: You mentioned that you should cut back on the seat heaters to extend range. Using the seat heaters on an EV uses very little electricity. For that reason, it is suggested that you USE the seat heater and cut back on the cabin temperature. Seat heaters are your friend.
sure this is a bit subjective. The same resistive heating elements are at play in both, so based on number of passengers, and personal preference, do what works for you! I like warm air on my feet
I get it. In the low range days of 75 to 85 miles, people would go to extremes in order to keep warm; blankets and boots were the norm. And thank you for all your hard work. I've owned five EVs since 2013, and around ten fossil cars. My Model 3 is by far the best car I've ever owned.
Yeah, you can set the heat to a lower setting, you should factor comfort, preference, and number of occupants. But do what makes the most sense for you, and do some experimenting! We'd love to see the data from anyone who does it!
Not really - most electric seat heaters use 90-120 watts of electricity. The electric-resistive heaters inside EV's range from 2500 - 6000 watts or more.
You recommend not running seat heaters, but it's much more energy efficient to run those with reduced cabin temps since the heat is direct to your body, and not dispersed through air in the cabin.
Yeah that is purely up to the user. Seat heaters usually aren’t enough for me. I prefer heat on my feet. But you’re totally right the heater in the seats use less energy than the cabin heater!
Seat heaters are fine up to -5/-10°c but colder then that you need the air too. At least my opinion. Maybe you live in a warmer area then myself, maybe not though
Rel life numbers: I bought a Model S in 2013. I got about 265 miles on a charge. 6.5 years later, I get about 259 miles on a full charge. So, the big range degradation story is a myth.
Do you charge your car to 100% and discharge it to say 10% to get maximum range? Or do you charge to 80% and discharge to 30% as stated in this video? I'm just wanting to understand how much of the battery pack's power reserve is used to get the range you state. Thank you.
Please, energy density in Wh/kg, not W/kg (power density). How can neophytes understand if everyone makes the mistake? I'm sorry to be aggressive but I'm annoyed everyone makes this mistake, even this pretty good channel! You cannot confuse these units talking about batteries, it's soo disappointing and it's not a small mistake, especially if this video is designed for engineers. *Great video anyway* :)
This was incredibly well done.. easy to recommend this as one of the best layman's breakdowns of this technology I have seen. Each of the 160K of us that have seen this so far.. have come away smarter from this well though-out presentation. Kudos to you for this.
You guys are making a professional effort to provide valuable information for everyone interested in Tesla. I have had a Model S for more than 3 years, and as much as I keep up, reading almost every article and seeing a great number of videos - your information and presentation is the most accurate, dense and complete I have seen. I have a recommendation: since you appear to be on track to basically create a 'Tesla Encyclopedia', I believe you might enhance the value of your project with an indexing system. An indexing system could be as simple or as complex as you choose to design. However, I see a complexly designed indexing system as eventually generating great rewards for both you and your viewers. It would be a big undertaking. 1. Simplicity from the start would only need to categorize your videos by subject matter - a 'table of contents'. 2. More complex would be to create an interactive tree of related material organized to send researchers logically to the level their prior research indicates would be most useful them, i.e., answer their questions before they ask them. 3. Much more complex would be to access timestamps within each video so that keyword searches could provide your viewers with links to related snippets across the breadth of your video library, giving very detailed access to all the material you accumulate. They could in effect build their own video. lol - maybe I'm making an impossible work project with this last suggestion. I suggest it because I absolutely see your efforts producing the quality and detail that is sure to satisfy Tesla researchers. After all, you are entering a rapidly expanding market.
I love this channel already. 3mins in and I can’t even stop thinking about how amazing it is for someone to not only get all this information but to make a 21min video on it. Haven’t watch the full video since I’m super tired from work but definitely will watch the rest later. Amazing work and content keep it.
15:58 -27C here in Finland last winter. My 2004 polo, semi faulty ignition, broken lambda, broken catalytic converter, leaking exhaust system. Starts with first crank albeit sounds a bit rough. Though that thing sucks money like a leech when you fix the issues it has :P
Even modern Diesel diesel engines does not require those gadgets. Whats great about those shots of the cars is that maker of this video does not know european car plates since those cars are from Russia where winters generally are way harsher than the -27C. And from what i see those shots the cars are from Tomsk Oblast are if you want to know thats West Syberian Plain which means in those EV probably would not even start during the winter.
You know you just defeated the whole point of having EV by your sentence, because it just show how much of denial. Great idea brand new battery for every winter. The thing even if manufacturer of battery says it can work -27C you really don't want it work in those conditions(in other words do go with your EV cars anywhere with temp. lower than -22C) since it would damage the battery so much that you will need a brand new one.
7:42 Third reason: Cellphones and Laptops don't have temperature controlling keeping the battery at proper temperatures when charging etc.. All in all these information, despite a few unironed spots, are incredibly well-prepared and also well-presented. Calmly, allowing to focus, think and understand. Thank you very much for your incredible work.
You tell truths that I agree with. Must caveat that by stating I've not seen the entire video and may or may not agree with some of your assertions. That aside what I have heard resonates. I was immediately on the heat problem, which you immediately explained in a clear and concise manner. Cuddos Dude! :)
I'm not sure about your advice to not use seat heaters. They draw only a few amps, but can improve comfort greatly. The best advice I've seen is to run the cabin heater until it's comfortable, then turn it down or off and then leave the seat heaters on to stay warm...
Totally I think that’s personal preference and honestly you can try some trial and error read your power consumption meter and see how it plays out! Share what you find
I concur. The seat heaters are nothing in the scheme of things. You'll save more power turning on the seat heaters and lowing the heat temp setting by 1 degree.
LEAF's use a HVAC system for heating and cooling generally. The lower trim level uses resistive heating. Also, heated seats are dramatically more efficient than heating the entire cabin.
Outstanding video-you are the best! 👍👍Very easy to follow and a very comprehensive technical breakdown of the model 3 battery. I look forward to the next video. Thank you.
[Ricky] Thank you! If you have ideas or questions about any of these topics, please don't be shy, we love bringing content our viewers actually want to see
I’m trying to keep my charging at no greater than 80% on a somewhat daily basis. Not necessary to charge every day, but keep plug in when at home. It will be interesting to see over time what effect this method will have on the battery life, as far as degradation. Had model 3 for less than a month about 770 miles so far. I’m using the app TezLab so my car data is being collected.
What, Tesla inverters don't look like clutch plates? Who knew? Maybe you could get Tesla to change their inverters so they look like clutch plates so the image in your video would be right.
Superb video - I've never seen you before. But very well done. Might have been worth mentioning that the Model 3 has the batteries pre-attached to the cooling ribbon to aid in assembly - it's like a machine gun's ammunition belt.
Karen Pease I found the battery cooling to be an interesting solution but wonder about the coolant system only having contact with a small percentage if the cell, it seems to rely heavily on the "thermal paste"
Thanks for the education. Taking delivery on our model 3 in a few days, and the information is very helpful. That was a lot of research for our benefit. Well done, Subscribed.
Dual motor, big battery, and enhanced autopilot. I went with the 18 inch aero wheels to soften the ride a bit. I don't care for the looks of the snap-on wheel cover, but the alloy wheel under it isn't bad looking. I'll snap on the covers when doing long distance driving. Really looking forward to saying goodbye to gasoline, oil/changes, transmission/fluid and around 2,000 other moving parts subject to failure. I appreciate the tips on charging, your work gave me a better understanding of battery health! Thanks!
I have a 2018 Honda Clarity PHEV and I'm loving it. Since buying the car (used) I've made about 20 trips, the majority of which were to work and back (23 mi each way) and my gas engine has only turned on once to do a "System Check" (a routine process to make sure it's working well) in the past 2.5 weeks. I have 283 miles of range in the nearly-full 7 gallon gas tank. I'll post back when I have to actually visit a gas station and fill up. :D I feel like Tesla is largely responsible for pushing manufacturers like Honda to make EVs and PHEVs.
So he buys one that has no oil cap.These cars are techy cars for techy people. So the Iphone generation should love them, if they can afford one. And then there is the minimalist movement, so let's all live in tiny houses, drive bikes, and grow your own food, yes?
13:35 The AC-DC Inverter image is an image of a clutch friction disc. I am not following the logic behind a mechanical torque transfer part having any relation to an electronic part.
@@jacko101 If you're referring to the "AC Motor" image, that's actually an alternator. "Electronics" is just a computer motherboard. TBdV needs better stock image skills.
nice work on correcting the mistakes in the previous video. Between these last two episodes I've checked in on, you definitely deserve a sub. Thanks for the hard work dude :)
BMS appears to be overhyped in this video. This is common as dirt in batteries. It's why cellphones don't spontaneously explode when given odd extremes like high current recharge but in a hot environment they slow down and in a common hybrid/ev the system will protect the batteries from reaching an event that can cause a fire. (overcurrent protection is why phones don't catch fire when left overnight while charging)
BMS systems are common as dirt now, but the difference between stuff in regular appliances and the really good stuff is night and day. In particular your cell phone or power tool BMS has absolutely no problems letting the battery die within the year, but manufacturers who guarantee a 10 year life span need to play a whole new ball game.
The BMS on the Tesla isn't nearly as advanced as the cell phone in many ways. It does NOT manage the charging of individual cells, rather only modules, and the only balancing being done is with bleed resistors which is wasting energy and rather crude (and this is done on the module level). However for the application this is normal as it is not possible due to cost to do individual cells. That said it is not any different from any other car on the market. There is nothing that is at all special. The module board takes care of itself and then just reports to the BMS. The main BMS is not doing the individual balancing. Also if you have a bad cell, the entire module still has to be scrapped. A cell phone with multiple battery packs actually manages the charge to each of the batteries and they are managed at a truly cellular level. The Tesla BMS does not do this They are completely different things.
Awesome video series. Very informative. Tesla battery technology and management system is so incredible. So glad they came up with it, making all Tesla's EVs a true and better alternatives to ICE vehicles. Thank you for the videos.
15:55 "In freezing temperatures, a lot of petrol cars won't even start" - which petrol cars are you referring to? Virtually all of the car manufacturers test their cars in arctic winter conditions and make sure they can be relied on. If you keep the battery of your petrol car charged, you should be able to start it in extremely cold conditions. A lot of car manufacturers test their cars here in the northern parts of Sweden, especially in the arctic winter. Sometimes the temperature can drop to about -40 degrees F or C (at -40 the two scales intersect), however the temperature can be below -20 degrees C/ -4 degrees F for weeks at a time in the winter. Northern Sweden and northern scandinavia in general is the land of great contrast. -40 degrees C/F extremes in the winter and almost 40 degrees C/104 degrees F extremes in the summer. Usually it stays between -30C/-22F in the winter and 30C/86F in the summer but the extremes do occur and once every few years there can be extremes of below -40C/F and above 40C/104F. Most people use electric heaters in the winter to warm their engines for significantly reduced wear and significantly increased comfort, but the cars are engineered to start in pretty extreme cold.
The starter battery, especially if a couple years old, could easily die after a couple cold starts in -40! Also, diesel are worse than petrol in those temps.
@@bistrovogna you can get your battery tested for cold cranking before winter a lot of place here in the UK will do it for free. Diesel engines will have a harder time starting but with modern engines we are talking of a just a couple more turns before it starts
A lot of people in the US drive old model cars. Still more people in the US don't pay a lot of attention to maintenance of their cars. Both of these conditions create a lot of petrol cars that don't start in the cold. We can't refute this point by assuming all petrol cars are modern, tested in Sweden, and fully maintained. We simply need to look at how many petrol cars a year call for roadside assistance because they wouldn't start in the cold.
I agree with GeFeldz. I've never experienced a modern FFE not starting just due to the cold. Quite simply, the statement is offered without evidence, or any real meaning. How many cars is "a lot?" "Freezing temperatures?" Which model cars can't manage under zero degrees Celsius?
Cute that you use a clutch plate as the figure for the DC-AC Inverter (which you called AC-DC inverter, which is backwards, AC-DC is done simply with rectifiers).
The electronics . The battery packs. The computer system. The motors. This is a really unique car design. No one else seems to have been able to do what Tesla has done. I was very critical of Tesla cars when I first began to study them. But the more I learn about them, the more I love them. I think Tesla has a lot of work to do expanding their service network. And also they are very poor at dealing with customer cars that are out of warranty. They are not hard to work on. Your presentation and amount of information is very impressive and exciting! Thanks for doing this great video. LIKED SUBSCRIBED and BELL RUNG. Glad I fount this channel today.
The thing that bothers me a bit is how he calls it "Tesla's battery" all the time, as if Panasonic isn't doing anything. Panasonic makes these batteries in the Gigafactory. They share the Gigafactory, with most of the space being for Panasonic. It's Tesla owned of course, and Tesla is a client for Panasonic, but it doesn't mean that Panasonic can't just get other clients, as well.
my model 3 is fast, silent, and charged by 17kw solar system in my backyard. Absolutely fun, but not free. The solar system cost $42000 after government incentive. That’s equivalent to 10years of my FPL bill. So after 10 years, if the system still works, I get my electricity free.
Just wanted to say something about the cold weather points mentioned. I've no experience at all with EVs, but my old Nissan Micra (1 litre petrol engine) never let me down in cold weather. It was parked outside all year and started first time, every time, however bad the winter. I bought it third-hand in 1996 and ran it happily till 2012, when I suddenly became poor, sold it, and went back to riding my old bicycle instead. I'm not sure where the idea that petrol cars can't handle freezing conditions came from. Diesel fuel IS affected by very cold weather. I think most lorries and trucks with exposed diesel fuel tanks have heaters to keep the fuel flowing in below-zero conditions. Once again, though, as far as I know, they start and run without any fuss in winter.
When people are talking about lithium reserves they're not talking about lithium stacked in the back of a warehouse somewhere. That refers to all of the resource that is economically feasible to extract. I'm not saying that's an issue to worry about right now, but the way you mentioned it in your narration made it sound like there's lots more to be had somewhere. That's not the case. 18:35
Wow! I was absolutely blown away by the production quality and the depth of knowledge contained in this presentation! Of course I immediately subscribed. I was also astounded by the quality of the Tesla systems and the forethought that went into their design and development. (I'm a Model S owner for about 18 months.) Thank you so much for this amazing video!
Not run the seat heaters???? I disagree with this advice. Heating the seat instead of the cabin air is a much more efficient way to get heat to the person in the seat. Thus, the method I use is to turn on the seat heaters first. In my mild climate this often lets me keep the cabin heat completely off. But, if it's colder, having the seat heaters on lets me have the same comfort level with a lower cabin heat setting. I don't know what the exact numbers are, but (full on) a cabin air heater might be around 5000 watts and a seat heater might be what 50 watts? So, I can run my seat heater for around 1-1/2 hours on the same amount of electricity that the cabin heater will use in one minute just warming up the coolant (assuming the cabin heat is a coolant based system).
Ricky I thought about this... and yeah you very well might be right. But it's a personal preference thing. I like having heat on my feet for example.. but yeah work it the best way for you :)
Andrew Snow so is cooling off the seats a better idea than the cabin air? I’m a hot climate 50 ish % of the year ( with ambient air temperatures of 35+C / 80F ) and I don’t like the swamp butt feeling or being burned by my Chrome seat parts or dark leather. Side-note how much energy Storage does it take in kilowatt hours to keep it cool for more than 3 hours @ under 75F?
I completely agree that different people will prefer different things and you should do what makes you the most comfortable. Driving an electric car shouldn't mean you have to be uncomfortable. The Tesla 3 uses about 240 watt-hours per mile, right? Thus, you would need to run a seat heater for about 5 hours to loose 1 mile of range. I'm just worried your comment in the video will give people the impression that the seat heaters are power-hungry like the cabin heat when they are really a very minor draw.
A cooled seat would save energy over cabin A/C, but that's not the only thing to consider. If the humidity level is low or moderate, then cooling the seats might make you comfortable. But, if the humidity is high, I think you will still be uncomfortable without the cabin air conditioning on. I think there are a few cars that come with cooled seats now, but if your care doesn't have them adding them would be a big complicated job. As for the amount of energy the used by the A/C, unfortunately I can't give you a solid number. But, at the small temperature difference you mentioned it is probably not too bad. My advice is to just test it. Assuming you have a place where you can safely leave the key in the car, then leave the car with the A/C running for an hour and see how much battery capacity is used. That's one of the things I like about my electric car. When I wait in my car for my wife, I can run the A/C without the huge waste of running a big gasoline engine. Calculating the amount of energy used by a (resistance) electric heater is rather easy -- a 1000 watt heater run (at full power) for an hour will use 1 kilowatt-hour of energy. An A/C system is much more difficult. First, I'd need to know the efficiency of the A/C system. I could make an educated guess, but at the small temperature difference you mentioned -- 80F outside and 75F inside, guessing the efficiency is going to be harder. Then there are the weather conditions (other than temperature) that will make a big difference - sun shining on the car, humidity (condensing water out of the air releases a lot of heat), and wind (to help the fans move hot air away from the condenser at the front of the car. If I HAD to make a guess, I would go with 1 kW-hr per hour (e.g. 3 kW-hr in 3 hours). But it could easily be half of this, or twice this, or maybe even more if the car is in the sun, the humidity is high, or the outside temperature is up a bit.
Future Hindsight not true. The heater runs dynamically. 5kW is just its max power. It might run at 5kW when it's snowing out and freezing inside. Then after it warms up, it just cycles as needed, as it's digitally controlled.
After watching part 1 and part 2, this seems more like a Tesla commercial than independent research. This seems especially evident with some of the statements about completing technologies. For instance I've never seen anywhere near a 50% loss in range of my Bolt due to cold. And I grew up in Wisconsin, and started our gas car in -50F temps at least once a year. (With no block heater.). There also is a lot of 'Tesla does it this way, that that's the best', without weighing the advantages or disadvantages of the various approaches. I also doubt the the battery design in other cars is based on 'what room was left over'. I found this interesting, but I feel like I need to watch videos produced by the other manufacturers to get a balanced point of view.
Claiming that "a lot of petrol cars won't even start in freezing temperatures" is a lie. Very FEW cars actually have that problem and overwhelmingly due to poor maintenance.
Well, if the petrol or diesel quality is poor, it can freeze in your tank. So no matter how well maintained your engine is, the car will not start before you heat the petrol.
My fossil eating car ,my little 2016 Toyota corolla has never had a problem starting in extreme cold. I'm from Alberta Canada. Where temperatures can drop to - 40 Celsius (-40 Fahrenheit). It will start even if I don't plug it in.
Yea ironically the battery is usually the reason a car won't start in the cold. I know batteries don't perform well in extreme temperatures. With Lipo batteries if you heat them above 110 degrees the voltage will go up and discharge faster.
@@freshcharge yeah usually in a gas car they use lead acid batteries which are more resistant to cold. I mean they still get affected. But a lot less than lithium. If a lead acid battery is charged. It can withstand -80 pretty easily. But if it dies in that temperature the liquid in the battery will freeze solid. And will be damaged permanently.
You have created the most succinct informational video I've seen to date about the current battery technology applicable to motorcars. There's a lot to learn regarding Lithium battery technology, and it's clear from your two-part video presentation that Tesla and Panasonic are worldwide leaders in the evolution of battery technology and electric cars.The future is promising, and it's exciting to be a small part of it. Kudos to your efforts and easy to understand videos!!
Well, then Tesla supplies the content if not the money. There is so much Tesla related info, and it would be impossible for anybody to get even some of them unless Tesla somehow provided them at will. Tesla's marketing department probably spend huge amounts of resources preparing the content. It is a way that Tesla operate. They secretly leak information to web sites and forums. By doing that, they are keeping a perfectly clean slate. If somebody realize that the data was misleading, evil, manipulated and what not, Tesla would be on the clear.
time for another metallic headwear adjustment. all of the information in this video has been widely available on numerous sites (many of them tesla detractor sites) for years.
Excellent and informative videos! You guys should receive some sort of award from Tesla. If you have additional parts in this series, please also address the charge retention issue of these rechargeable batteries in EVs. Unlike gasoline cars where no one expects the fuel would evaporate after a long idle time, EVs have this unique issue of losing range in idle, just like an iPad that is in idle or even turned off. This prevents people from parking their EVs in the airport unplugged for a long vacation. I think this is an important and overlooked issue of EVs. Teslanomics actually has a video comparing the phantom battery drain of different Tesla models, and Model 3 ranks the worst with an average loss of about 12-15 miles every day which eats significantly into the efficiency of the car. Most importantly, a model 3 can end up with a permanent battery damage if left unplugged and unattended for a long period of time, which is highly undesirable.
Great point the series got so big we couldn’t cover absolutely everything but yes we’ll cover more topics like discharge during storage / retention in future videos!!
Got no problem starting my diesel when its -40 But i would rather have a petrol when its that cold because some diesels like our X trail can not produce enough heat to warm the car when its that cold, but my A4 2.5 can. Sure i know there are solutions, but I would rather have a petrol car when its winter. Then i don't have to remember to mix petrol and diesel when i am filling our diesel cars. Don't see myself owning a Tesla or a electric.
WinnyJ1. Mixing diesel and petrol together to prevent it freezing in winter, I haven't used that idea since the worst winter ever in the UK in 1962/3 when if froze for 12 weeks solid. Since then the wax which used to cause the gelling problem has all but been eliminated from diesel fuel plus additives are added in winter fuel. If you live in extremely cold climates and diesel gelling is still a problem then just add 25 per cent Kerosene to your fuel which will solve the problem, you don't see commercial airline jets having problems with freezing fuel at -50dc when at 40,000 ft but they use 100 per cent jet fuel which is basically Kerosene, putting petrol in one of the high pressure direct injection Diesel engines is Not a good idea because petrol is a spirit and has no lubricating properties in it so may cause very expensive damage to the fuel injection system.
Amazing video. tons of great information. I recently started harvesting 18650's out of old electronics to build a small powerwall.. It's 2 fold. I saved em from going to the landfill, and I'm learning.
16:55 - I think that is where Tesla's acquisition of Maxwell Technology comes into play. Tesla can integrate Maxwell's capacitors to capture regen engergy while the Li-Ion batteries heats up to optimal temps.
interesting that in 2020 this topic has only 4 thumbs up. this whole thing is DRIVEN by battery technology - that's why it didn't take off earlier - pitiful batteries. The combination of Li-ion and capacitors opens up a new chapter - humbly IMO. Isn't the final answer, but so much better than anything else right now.
4:24 Talking about density in terms of watts per kilogram doesn't make much sense. Peak power does matter but in this context I think you meant to be talking about watt-hours/kilogram or joules/kilogram. Energy density not power density.
Yes, Nissan put heat-pump heaters (like a reversed AC) in 2013 and above. 2011 & 2012 used resistive heating which can only be 100% efficient at best (1 KW of electricity gives 1 KW of heat). Heat pumps allow efficiency far above 1:1!
Lounge lizard, efficiency can never be >1. What you mean to say is that it costs less power to transport heat generated with even more power. e.g. you can heat air with a 3kW heating element but it will take maybe only 600W to move it around.
@@petrvalkoun4539 that's not how efficiency works LOL You're right though, heat energy can be measured in watts, but it's nowhere near 300-400%. It's claimed 100% efficient because 100% of the energy that goes in comes out as 100% heat (because we *want* heat, whereas normal electronics heat is undesirable, which detracts from efficiency), however it also introduces wear on the heating element, which takes away from efficiency.. However that heat is then dispersed into the air which can only take so much so quickly (heat capacity) and can only transfer so much so quickly. If you hold your hand to the heater to warm it up, you'll get near 100% efficiency, but any time you add a medium to transfer heat through before it reaches your end target, you're losing heat to it, and air is one of the worst mediums to try and transfer heat.
At 13:47 what you call a AC/DC Inverter looks like a clutch plate to me. One of the many thing missing in a Tesla. Your incorrect graphics make me question the rest of your story.
Haha yeah we have limited graphic assets and we couldn’t render any more 3D to meet our launch date. We had over 100 hours of rendered content in that video
Thats a classic. Please keep it. I like the way we are going with electric cars as far as helping with the environment but that does not mean ice cars will lose their appeal. Think of the enthusiasts for steam engines. Horribly polluting but such a small number these days that their impact is ignored. The same will happen in due course with ice vehicles. That's progress and it will happen naturally. I for one will be happy to drive my electric car to a race track or rally and drive an old ice classic from time to time.
I wish looking back on my life at 65 now I would have kept my 69 camero/3 bedroom house in San Diego 6 blocks from the beach in PB for 69,000.00 bucks/and big beautiful racked girl friend I had in high school!!
@@jimhood1202 Likely going to cause more environmental damage producing these batteries, already is doing so with cordless power tools Also major funding ( 30 billion) funding for cold fusion with uranium assistance(pardon me I am not a nuclear physicist) from the Canadian government? I don't get it!! "little girl save the world" from Sweden the savior to do right, Their country burns garbage and plastic to spin turbines to make power to charge their electric cars! Heat factories and homes! What gives her the right to come and preach to Canada that we are major greenhouse gas polluters? She should be sent to India or HOng Kong. Be shot and set on fire. Little Rich kid hypocrite! Keep the El Camino!!! will be less polluting burning gasoline!!
Also "in cold temperatures, alot of petrol cars won't even start" what is this, the 1960s? In freezing temperatures (also bad for batteries) contaminated fuel may freeze, causing issues. In freezing temperatures, diesel engines may be disabled without external pre-heating. Also, the line of cars are using battery heaters, like the teslas of the future will need..... Any temperature that is bad for an ICE, is also bad for a motor/batteries.
then there is russian lada petrol engines that have a rated starting temp of -40c and with some convincing can do -60c , batteries at that temp just WONT work.
I like the idea Tesla Engineers start from scratch if need be instead of piggy backing on existing technology to save money. This is costly but can have big leaps forward that were stopping other car companies.
How do you make the 3d walk throughs? I am thoroughly impressed with the professional quality

I feel like the big hype about the factories polluting more than ever to produce batteries is kind of silly, if I'm honest. Why? Well, when we get to the point that there are more EVs are on the road than ICE, wouldn't that drastically lessen the pollution impact than, say, a few factories here and there? You also have to remember, by the time EVs are 60-70% of our cars on the road, battery tech will have significantly advanced. So while the ramp-up might be the most polluting, the long-term goal might be well worth it, yes?
Porsche Duésnburg , please also remember that the Country full of EVs will drastically demand more electricity generation. In the US, electricity is generated mostly by power plants burning dirty fuels like coal, petrol and similar as well as nuclear power plants, which can result in much higher levels of air, water and ambient pollution. Of course there are also many “clean” power plants like hydraulic, wind, solar, etc. but not as much!

Obviously not as clean as wind, solar and water but not anything near as dirty as coals etc. In a dense area like Beijing, I could see that being an issue. But most of those people utilize bikes and walking anyway, cars there are typically for higher class and/or people who just don't want to be bothered by the garish traffic. Same for NYC, most people down there don't even own a car and just rideshare everywhere they need to go that's out of reasonable walking distance. So I still stand behind what I said prior. But if I'm honest, I don't think the goal should be to force petrol totally out. Petrol still has it's uses. But drastically reducing the dependency on it would be much better than where we are now :) Like me, I'm fully onboard with EVs now, thanks Tesla and Fisker. I'm saving to get a Model 3 Performance or AWD LR at very least but not giving up my Datsun 260 and will keep a petrol engine in it. It will be my toy car only once I have an EV daily.
Does anyone know the efficiency of the model 3 motor? Being a PM motor, it should be over 90%??- Looking forward to your life cycle analysis, i.e. how long you need to drive your Tesla before you've emitted less than sticking with your petrol car. About winter driving: 4WD is really not needed and is an extra penalty when fighting reduced battery capacity. Keeping the battery warm when you need it, is simply a matter of programming your charger to finish when you need the car for your morning commute. That also makes it charge at night where electricity is cheapest.

Thank you so much for saying that... it really is motivating :) We have a lot of great stuff in the works!
Two Bit da Vinci, very impressed. Thanks for the insight!
First visit to your channel and you can't convert units, not a very good reason to follow you.
Inaccuracy kills a source.
Two Bit da Vinci Pretty much spot on. But did you mention that the rear motor can be used in waste heat mode to heat up the car really well, especially start ups for the days beside software preconditioning/predictions.
One tiny little quibble: You mentioned that you should cut back on the seat heaters to extend range. Using the seat heaters on an EV uses very little electricity. For that reason, it is suggested that you USE the seat heater and cut back on the cabin temperature. Seat heaters are your friend.
sure this is a bit subjective. The same resistive heating elements are at play in both, so based on number of passengers, and personal preference, do what works for you! I like warm air on my feet
I get it. In the low range days of 75 to 85 miles, people would go to extremes in order to keep warm; blankets and boots were the norm. And thank you for all your hard work. I've owned five EVs since 2013, and around ten fossil cars. My Model 3 is by far the best car I've ever owned.
The dash heater can draw thousands of watts. The seat heaters are in the low hundreds.
Yeah, you can set the heat to a lower setting, you should factor comfort, preference, and number of occupants. But do what makes the most sense for you, and do some experimenting! We'd love to see the data from anyone who does it!
Not really - most electric seat heaters use 90-120 watts of electricity. The electric-resistive heaters inside EV's range from 2500 - 6000 watts or more.
You recommend not running seat heaters, but it's much more energy efficient to run those with reduced cabin temps since the heat is direct to your body, and not dispersed through air in the cabin.
Yeah that is purely up to the user. Seat heaters usually aren’t enough for me. I prefer heat on my feet. But you’re totally right the heater in the seats use less energy than the cabin heater!
Seat heaters are fine up to -5/-10°c but colder then that you need the air too. At least my opinion. Maybe you live in a warmer area then myself, maybe not though
If you spent that kinda money on a car... your gona sit in it and be cold? LOL. I'm toasty warm in my POS 80's diesel...
@Matt Lane you might be focusing on the wrong thing here...
Living where I do, I literally never turn on my car's heater. A/C runs for 9 months a year though.
This side of UA-cam is called: knowledge!
Rel life numbers: I bought a Model S in 2013. I got about 265 miles on a charge. 6.5 years later, I get about 259 miles on a full charge.
So, the big range degradation story is a myth.
That’s fantastic data, thanks for sharing!
Do you charge your car to 100% and discharge it to say 10% to get maximum range?
Or do you charge to 80% and discharge to 30% as stated in this video?
I'm just wanting to understand how much of the battery pack's power reserve is used to get the range you state.
Thank you.
Try tesla in snow and cold
@@StopTeoriomSpiskowym doesn't the batterys warm up quite fast anyways?
But you are not saving the world either. That is a myth too
Please, energy density in Wh/kg, not W/kg (power density). How can neophytes understand if everyone makes the mistake? I'm sorry to be aggressive but I'm annoyed everyone makes this mistake, even this pretty good channel! You cannot confuse these units talking about batteries, it's soo disappointing and it's not a small mistake, especially if this video is designed for engineers. *Great video anyway* :)
Hahaha. So true, and such a frequent mistake
Being a UA-camr is very hard,
much respect to this high quality Engineering video.
He(and so many others) makes this mistake in almost every video. Even in the newer ones still.
This was incredibly well done.. easy to recommend this as one of the best layman's breakdowns of this technology I have seen. Each of the 160K of us that have seen this so far.. have come away smarter from this well though-out presentation. Kudos to you for this.
Wow ... that's a great compliment, thank you so much!
You guys are making a professional effort to provide valuable information for everyone interested in Tesla.
I have had a Model S for more than 3 years, and as much as I keep up, reading almost every article and seeing a great number of videos - your information and presentation is the most accurate, dense and complete I have seen.
I have a recommendation: since you appear to be on track to basically create a 'Tesla Encyclopedia', I believe you might enhance the value of your project with an indexing system.
An indexing system could be as simple or as complex as you choose to design.
However, I see a complexly designed indexing system as eventually generating great rewards for both you and your viewers. It would be a big undertaking.
1. Simplicity from the start would only need to categorize your videos by subject matter - a 'table of contents'.
2. More complex would be to create an interactive tree of related material organized to send researchers logically to the level their prior research indicates would be most useful them, i.e., answer their questions before they ask them.
3. Much more complex would be to access timestamps within each video so that keyword searches could provide your viewers with links to related snippets across the breadth of your video library, giving very detailed access to all the material you accumulate. They could in effect build their own video.
lol - maybe I'm making an impossible work project with this last suggestion. I suggest it because I absolutely see your efforts producing the quality and detail that is sure to satisfy Tesla researchers. After all, you are entering a rapidly expanding market.
we're going to digest this awesome quote, and we'll keep in touch with you going forward!
I love this channel already. 3mins in and I can’t even stop thinking about how amazing it is for someone to not only get all this information but to make a 21min video on it. Haven’t watch the full video since I’m super tired from work but definitely will watch the rest later. Amazing work and content keep it.
15:58
-27C here in Finland last winter.
My 2004 polo, semi faulty ignition, broken lambda, broken catalytic converter, leaking exhaust system.
Starts with first crank albeit sounds a bit rough.
Though that thing sucks money like a leech when you fix the issues it has :P
He meant Diesel not Petrol engines.
Even modern Diesel diesel engines does not require those gadgets. Whats great about those shots of the cars is that maker of this video does not know european car plates since those cars are from Russia where winters generally are way harsher than the -27C. And from what i see those shots the cars are from Tomsk Oblast are if you want to know thats West Syberian Plain which means in those EV probably would not even start during the winter.
your car battery must be brand new then!!
You know you just defeated the whole point of having EV by your sentence, because it just show how much of denial. Great idea brand new battery for every winter. The thing even if manufacturer of battery says it can work -27C you really don't want it work in those conditions(in other words do go with your EV cars anywhere with temp. lower than -22C) since it would damage the battery so much that you will need a brand new one.
I have a car fail to start every winter in finland. And ive owned 5 brand new ones. Joka vitun talvi
7:42 Third reason: Cellphones and Laptops don't have temperature controlling keeping the battery at proper temperatures when charging etc..
All in all these information, despite a few unironed spots, are incredibly well-prepared and also well-presented. Calmly, allowing to focus, think and understand. Thank you very much for your incredible work.
You tell truths that I agree with. Must caveat that by stating I've not seen the entire video and may or may not agree with some of your assertions. That aside what I have heard resonates. I was immediately on the heat problem, which you immediately explained in a clear and concise manner.
Cuddos Dude! :)
This is the channel to be. The depth of these videos is simply mind boggling 😊
I'm not sure about your advice to not use seat heaters. They draw only a few amps, but can improve comfort greatly. The best advice I've seen is to run the cabin heater until it's comfortable, then turn it down or off and then leave the seat heaters on to stay warm...
Totally I think that’s personal preference and honestly you can try some trial and error read your power consumption meter and see how it plays out! Share what you find
I concur. The seat heaters are nothing in the scheme of things. You'll save more power turning on the seat heaters and lowing the heat temp setting by 1 degree.
LEAF's use a HVAC system for heating and cooling generally. The lower trim level uses resistive heating. Also, heated seats are dramatically more efficient than heating the entire cabin.
Excellent video Ricky !!!
This was really great guys the depth was refreshing subed and liked
Thanks Jason! We are planning a part 3 to cover recycling later this year
Pleasing to listen to and watch. Thank you !
Thanks Victor!
Great video!
Outstanding video-you are the best! 👍👍Very easy to follow and a very comprehensive technical breakdown of the model 3 battery. I look forward to the next video. Thank you.
[Ricky] Thank you! If you have ideas or questions about any of these topics, please don't be shy, we love bringing content our viewers actually want to see
I’m trying to keep my charging at no greater than 80% on a somewhat daily basis. Not necessary to charge every day, but keep plug in when at home. It will be interesting to see over time what effect this method will have on the battery life, as far as degradation. Had model 3 for less than a month about 770 miles so far. I’m using the app TezLab so my car data is being collected.
So much raw materials! I am totally sold. All questions answered!
Another superb job guys!
Great videos but why use a clutch plate graphic as the inverter? And didn't I see a turbo in there too?
lol... Limited Visual assets...hopefully you get the gist :)
Yeah it's fantastic!!!! Great work!!!
What, Tesla inverters don't look like clutch plates? Who knew? Maybe you could get Tesla to change their inverters so they look like clutch plates so the image in your video would be right.
It would be nice to see Tesla offer a manual tranny, as an option! 8)
Again very professional. I'm impressed. Very good infos. Thank You!
Thank you so much Jacques!
Superb video - I've never seen you before. But very well done.
Might have been worth mentioning that the Model 3 has the batteries pre-attached to the cooling ribbon to aid in assembly - it's like a machine gun's ammunition belt.
Yeah not sure if we were clean on that, but thanks for the info!
Karen Pease
I found the battery cooling to be an interesting solution but wonder about the coolant system only having contact with a small percentage if the cell, it seems to rely heavily on the "thermal paste"
@@paulcalmond Actually it looks like it has almost half of one complete side in contact with the cooling ribbon- more than I thought it would.
Thanks for the education. Taking delivery on our model 3 in a few days, and the information is very helpful. That was a lot of research for our benefit. Well done, Subscribed.
Congrats! What configuration!
Dual motor, big battery, and enhanced autopilot. I went with the 18 inch aero wheels to soften the ride a bit. I don't care for the looks of the snap-on wheel cover, but the alloy wheel under it isn't bad looking. I'll snap on the covers when doing long distance driving.
Really looking forward to saying goodbye to gasoline, oil/changes, transmission/fluid and around 2,000 other moving parts subject to failure.
I appreciate the tips on charging, your work gave me a better understanding of battery health! Thanks!
I believe you spent time on this. Excellent content. Subscribed
Watt hours / kg, not Watts! WattHour = energy, Watt = power
Watt/kg is also a very useful metric. When was this said?
4:24. It's a mistake.
watthour or Joule?
really appreciate the last mentioning of your effort in the making of this video
love the video and explanation...thank you for making this.
Nicely done many thanks
I have a 2018 Honda Clarity PHEV and I'm loving it. Since buying the car (used) I've made about 20 trips, the majority of which were to work and back (23 mi each way) and my gas engine has only turned on once to do a "System Check" (a routine process to make sure it's working well) in the past 2.5 weeks. I have 283 miles of range in the nearly-full 7 gallon gas tank. I'll post back when I have to actually visit a gas station and fill up. :D I feel like Tesla is largely responsible for pushing manufacturers like Honda to make EVs and PHEVs.
Great video man, Looking forward to the following videos. Keep it going my dude.
Thanks Ali, if you have ideas or questions for future videos, don't be shy!
This is great set of videos excellent info with high production value
You deserve much more subs! Nice Vid.
Thank so much! We have a lot more planned in the coming weeks!
Thank you! well produced, a wealth of information, and no dumming down. Wish there where more show on UA-cam like yours.
12:41 That's the FIRST time that guy has ever removed an oil cap!!! :D
So he buys one that has no oil cap.These cars are techy cars for techy people.
So the Iphone generation should love them, if they can afford one.
And then there is the minimalist movement, so let's all live in tiny houses, drive bikes, and grow your own food, yes?
Yep, you can tell! Good spot.
13:35 The AC-DC Inverter image is an image of a clutch friction disc. I am not following the logic behind a mechanical torque transfer part having any relation to an electronic part.
Also, the pump image is an image of a Turbo not a water pump.
@@jacko101 If you're referring to the "AC Motor" image, that's actually an alternator. "Electronics" is just a computer motherboard. TBdV needs better stock image skills.
nice work on correcting the mistakes in the previous video. Between these last two episodes I've checked in on, you definitely deserve a sub. Thanks for the hard work dude :)
BMS appears to be overhyped in this video. This is common as dirt in batteries. It's why cellphones don't spontaneously explode when given odd extremes like high current recharge but in a hot environment they slow down and in a common hybrid/ev the system will protect the batteries from reaching an event that can cause a fire. (overcurrent protection is why phones don't catch fire when left overnight while charging)
yeah, but your phone BMS isn't monitoring 4000 individual cells. So can be both as common as dirt, but especially good
BMS systems are common as dirt now, but the difference between stuff in regular appliances and the really good stuff is night and day.
In particular your cell phone or power tool BMS has absolutely no problems letting the battery die within the year, but manufacturers who guarantee a 10 year life span need to play a whole new ball game.
The BMS on the Tesla isn't nearly as advanced as the cell phone in many ways. It does NOT manage the charging of individual cells, rather only modules, and the only balancing being done is with bleed resistors which is wasting energy and rather crude (and this is done on the module level). However for the application this is normal as it is not possible due to cost to do individual cells. That said it is not any different from any other car on the market. There is nothing that is at all special. The module board takes care of itself and then just reports to the BMS. The main BMS is not doing the individual balancing. Also if you have a bad cell, the entire module still has to be scrapped. A cell phone with multiple battery packs actually manages the charge to each of the batteries and they are managed at a truly cellular level. The Tesla BMS does not do this They are completely different things.
The Bms is monitoring each parallel set, not individual cells.
that what they do in RC hobby since like ages....
Awesome video series. Very informative. Tesla battery technology and management system is so incredible. So glad they came up with it, making all Tesla's EVs a true and better alternatives to ICE vehicles. Thank you for the videos.
Brilliant video series. I look forward watching to Part 3.
15:55 "In freezing temperatures, a lot of petrol cars won't even start" - which petrol cars are you referring to? Virtually all of the car manufacturers test their cars in arctic winter conditions and make sure they can be relied on. If you keep the battery of your petrol car charged, you should be able to start it in extremely cold conditions. A lot of car manufacturers test their cars here in the northern parts of Sweden, especially in the arctic winter. Sometimes the temperature can drop to about -40 degrees F or C (at -40 the two scales intersect), however the temperature can be below -20 degrees C/ -4 degrees F for weeks at a time in the winter. Northern Sweden and northern scandinavia in general is the land of great contrast. -40 degrees C/F extremes in the winter and almost 40 degrees C/104 degrees F extremes in the summer. Usually it stays between -30C/-22F in the winter and 30C/86F in the summer but the extremes do occur and once every few years there can be extremes of below -40C/F and above 40C/104F.
Most people use electric heaters in the winter to warm their engines for significantly reduced wear and significantly increased comfort, but the cars are engineered to start in pretty extreme cold.
The starter battery, especially if a couple years old, could easily die after a couple cold starts in -40! Also, diesel are worse than petrol in those temps.
@@bistrovogna you can get your battery tested for cold cranking before winter a lot of place here in the UK will do it for free. Diesel engines will have a harder time starting but with modern engines we are talking of a just a couple more turns before it starts
I use to have to plug my cavalier in every night in North Dakota or it wouldn't start the next day. block heater it was called
A lot of people in the US drive old model cars. Still more people in the US don't pay a lot of attention to maintenance of their cars. Both of these conditions create a lot of petrol cars that don't start in the cold. We can't refute this point by assuming all petrol cars are modern, tested in Sweden, and fully maintained. We simply need to look at how many petrol cars a year call for roadside assistance because they wouldn't start in the cold.
I agree with GeFeldz. I've never experienced a modern FFE not starting just due to the cold. Quite simply, the statement is offered without evidence, or any real meaning. How many cars is "a lot?" "Freezing temperatures?" Which model cars can't manage under zero degrees Celsius?
I'd like this 10 times if I could this is hands down the best video on the topic made so far.
Thanks so much! We're always open to hearing great ideas/questions for future videos!
Okay sure, Rimac is very interesting.
Ah you read our minds, that is going to be out before years end, we assure you!
Cute that you use a clutch plate as the figure for the DC-AC Inverter (which you called AC-DC inverter, which is backwards, AC-DC is done simply with rectifiers).
Ele Truk and yet there is still some nutjob insisting that Tesla is supplying him with their own graphics. lol.
The electronics . The battery packs. The computer system. The motors. This is a really unique car design. No one else seems to have been able to do what Tesla has done. I was very critical of Tesla cars when I first began to study them. But the more I learn about them, the more I love them. I think Tesla has a lot of work to do expanding their service network. And also they are very poor at dealing with customer cars that are out of warranty. They are not hard to work on. Your presentation and amount of information is very impressive and exciting! Thanks for doing this great video. LIKED SUBSCRIBED and BELL RUNG. Glad I fount this channel today.
I really appreciate all of the research you did for our benefit! You rock!
The thing that bothers me a bit is how he calls it "Tesla's battery" all the time, as if Panasonic isn't doing anything. Panasonic makes these batteries in the Gigafactory. They share the Gigafactory, with most of the space being for Panasonic. It's Tesla owned of course, and Tesla is a client for Panasonic, but it doesn't mean that Panasonic can't just get other clients, as well.
I want my next car to be wicked fast, totally silent, and run on the sunlight hitting my roof at home. Fun is good, but FREE fun is better.
sorry nothing is free, no idea where you get these ideas
If you only rely on the sunlight hitting your roof, you won’t go very far... and all these things aren’t free...
my model 3 is fast, silent, and charged by 17kw solar system in my backyard. Absolutely fun, but not free. The solar system cost $42000 after government incentive. That’s equivalent to 10years of my FPL bill. So after 10 years, if the system still works, I get my electricity free.
This video is more emotional than being technical HAHAHA :) Thank you ! Viel Erfolg !
Fascinating videos on Tesla battery technology. Extremely engaging content.
I love channels that admit their mistakes. Liked
The picture of your AC/DC Inverter is a Clutch Plate lol???
Yeah noticed it too
Yeah, also spent a while looking at that! I think a AC/DC converter would have fewer moving parts!
This is some real high quality video. Both in terms of production and content. Very brilliant research done ! Thank you
Thank you for correcting the materials cost error in part 1.
Just wanted to say something about the cold weather points mentioned. I've no experience at all with EVs, but my old Nissan Micra (1 litre petrol engine) never let me down in cold weather. It was parked outside all year and started first time, every time, however bad the winter. I bought it third-hand in 1996 and ran it happily till 2012, when I suddenly became poor, sold it, and went back to riding my old bicycle instead. I'm not sure where the idea that petrol cars can't handle freezing conditions came from. Diesel fuel IS affected by very cold weather. I think most lorries and trucks with exposed diesel fuel tanks have heaters to keep the fuel flowing in below-zero conditions. Once again, though, as far as I know, they start and run without any fuss in winter.
A great pair of videos... thank you!
When people are talking about lithium reserves they're not talking about lithium stacked in the back of a warehouse somewhere. That refers to all of the resource that is economically feasible to extract. I'm not saying that's an issue to worry about right now, but the way you mentioned it in your narration made it sound like there's lots more to be had somewhere. That's not the case. 18:35
Spoken tempo just right, nice graphics, thanks for the info and your good work, greetings from Germany 👍

an actual computer guy would know that is not a motherboard... stoooop
@@d4ze7385 Thats exactly what a motherboard looks like, even tough the pcie slots are drawn backwards.
At 4:34 where it's 167 watts/kg should be 167 wh/kg. That's gravimetric energy density. Gravimetric power density has the units W/kg.
Yes good point, sorry for the mix up there
Wow! I was absolutely blown away by the production quality and the depth of knowledge contained in this presentation! Of course I immediately subscribed. I was also astounded by the quality of the Tesla systems and the forethought that went into their design and development. (I'm a Model S owner for about 18 months.) Thank you so much for this amazing video!
Fascinating. Informative. Entertaining. SCIENCE!
What a great series!!
Not run the seat heaters????
I disagree with this advice. Heating the seat instead of the cabin air is a much more efficient way to get heat to the person in the seat. Thus, the method I use is to turn on the seat heaters first. In my mild climate this often lets me keep the cabin heat completely off. But, if it's colder, having the seat heaters on lets me have the same comfort level with a lower cabin heat setting.
I don't know what the exact numbers are, but (full on) a cabin air heater might be around 5000 watts and a seat heater might be what 50 watts? So, I can run my seat heater for around 1-1/2 hours on the same amount of electricity that the cabin heater will use in one minute just warming up the coolant (assuming the cabin heat is a coolant based system).
Ricky I thought about this... and yeah you very well might be right. But it's a personal preference thing. I like having heat on my feet for example.. but yeah work it the best way for you :)
Andrew Snow so is cooling off the seats a better idea than the cabin air? I’m a hot climate 50 ish % of the year ( with ambient air temperatures of 35+C / 80F ) and I don’t like the swamp butt feeling or being burned by my Chrome seat parts or dark leather. Side-note how much energy Storage does it take in kilowatt hours to keep it cool for more than 3 hours @ under 75F?
I completely agree that different people will prefer different things and you should do what makes you the most comfortable. Driving an electric car shouldn't mean you have to be uncomfortable.
The Tesla 3 uses about 240 watt-hours per mile, right? Thus, you would need to run a seat heater for about 5 hours to loose 1 mile of range. I'm just worried your comment in the video will give people the impression that the seat heaters are power-hungry like the cabin heat when they are really a very minor draw.
A cooled seat would save energy over cabin A/C, but that's not the only thing to consider. If the humidity level is low or moderate, then cooling the seats might make you comfortable. But, if the humidity is high, I think you will still be uncomfortable without the cabin air conditioning on.
I think there are a few cars that come with cooled seats now, but if your care doesn't have them adding them would be a big complicated job.
As for the amount of energy the used by the A/C, unfortunately I can't give you a solid number. But, at the small temperature difference you mentioned it is probably not too bad. My advice is to just test it. Assuming you have a place where you can safely leave the key in the car, then leave the car with the A/C running for an hour and see how much battery capacity is used. That's one of the things I like about my electric car. When I wait in my car for my wife, I can run the A/C without the huge waste of running a big gasoline engine.
Calculating the amount of energy used by a (resistance) electric heater is rather easy -- a 1000 watt heater run (at full power) for an hour will use 1 kilowatt-hour of energy. An A/C system is much more difficult. First, I'd need to know the efficiency of the A/C system. I could make an educated guess, but at the small temperature difference you mentioned -- 80F outside and 75F inside, guessing the efficiency is going to be harder. Then there are the weather conditions (other than temperature) that will make a big difference - sun shining on the car, humidity (condensing water out of the air releases a lot of heat), and wind (to help the fans move hot air away from the condenser at the front of the car.
If I HAD to make a guess, I would go with 1 kW-hr per hour (e.g. 3 kW-hr in 3 hours). But it could easily be half of this, or twice this, or maybe even more if the car is in the sun, the humidity is high, or the outside temperature is up a bit.
Future Hindsight not true. The heater runs dynamically. 5kW is just its max power. It might run at 5kW when it's snowing out and freezing inside. Then after it warms up, it just cycles as needed, as it's digitally controlled.
After watching part 1 and part 2, this seems more like a Tesla commercial than independent research. This seems especially evident with some of the statements about completing technologies. For instance I've never seen anywhere near a 50% loss in range of my Bolt due to cold. And I grew up in Wisconsin, and started our gas car in -50F temps at least once a year. (With no block heater.). There also is a lot of 'Tesla does it this way, that that's the best', without weighing the advantages or disadvantages of the various approaches. I also doubt the the battery design in other cars is based on 'what room was left over'. I found this interesting, but I feel like I need to watch videos produced by the other manufacturers to get a balanced point of view.
Claiming that "a lot of petrol cars won't even start in freezing temperatures" is a lie. Very FEW cars actually have that problem and overwhelmingly due to poor maintenance.
Well, if the petrol or diesel quality is poor, it can freeze in your tank. So no matter how well maintained your engine is, the car will not start before you heat the petrol.
My fossil eating car ,my little 2016 Toyota corolla has never had a problem starting in extreme cold. I'm from Alberta Canada. Where temperatures can drop to - 40 Celsius (-40 Fahrenheit). It will start even if I don't plug it in.
Yea ironically the battery is usually the reason a car won't start in the cold. I know batteries don't perform well in extreme temperatures. With Lipo batteries if you heat them above 110 degrees the voltage will go up and discharge faster.
@@freshcharge yeah usually in a gas car they use lead acid batteries which are more resistant to cold. I mean they still get affected. But a lot less than lithium. If a lead acid battery is charged. It can withstand -80 pretty easily. But if it dies in that temperature the liquid in the battery will freeze solid. And will be damaged permanently.
idk wtf u drive and where u live but Ive had every single car, new or old, expensive or not, not start at least once a winter in Finland.
Your videos are relaxing
You have created the most succinct informational video I've seen to date about the current battery technology applicable to motorcars. There's a lot to learn regarding Lithium battery technology, and it's clear from your two-part video presentation that Tesla and Panasonic are worldwide leaders in the evolution of battery technology and electric cars.The future is promising, and it's exciting to be a small part of it. Kudos to your efforts and easy to understand videos!!
Where is the money coming from to do these videos? The animation alone must have taken weeks.... subscribed
(at 4:35 you mean WHrs/Kg not watts)
probably from a large organisation taht has a vested interest in looking good...
Probably Tesla, since this channel only has Tesla related videos.
I seriously doubt it
Well, then Tesla supplies the content if not the money. There is so much Tesla related info, and it would be impossible for anybody to get even some of them unless Tesla somehow provided them at will. Tesla's marketing department probably spend huge amounts of resources preparing the content.
It is a way that Tesla operate. They secretly leak information to web sites and forums. By doing that, they are keeping a perfectly clean slate. If somebody realize that the data was misleading, evil, manipulated and what not, Tesla would be on the clear.
time for another metallic headwear adjustment.
all of the information in this video has been widely available on numerous sites (many of them tesla detractor sites) for years.
Excellent and informative videos! You guys should receive some sort of award from Tesla. If you have additional parts in this series, please also address the charge retention issue of these rechargeable batteries in EVs. Unlike gasoline cars where no one expects the fuel would evaporate after a long idle time, EVs have this unique issue of losing range in idle, just like an iPad that is in idle or even turned off. This prevents people from parking their EVs in the airport unplugged for a long vacation. I think this is an important and overlooked issue of EVs. Teslanomics actually has a video comparing the phantom battery drain of different Tesla models, and Model 3 ranks the worst with an average loss of about 12-15 miles every day which eats significantly into the efficiency of the car. Most importantly, a model 3 can end up with a permanent battery damage if left unplugged and unattended for a long period of time, which is highly undesirable.
Great point the series got so big we couldn’t cover absolutely everything but yes we’ll cover more topics like discharge during storage / retention in future videos!!
Two Bit da Vinci, fantastic! Thanks.
Got no problem starting my diesel when its -40
But i would rather have a petrol when its that cold because some diesels like our X trail can not produce enough heat to warm the car when its that cold, but my A4 2.5 can.
Sure i know there are solutions, but I would rather have a petrol car when its winter.
Then i don't have to remember to mix petrol and diesel when i am filling our diesel cars.
Don't see myself owning a Tesla or a electric.
WinnyJ1. Mixing diesel and petrol together to prevent it freezing in winter, I haven't used that idea since the worst winter ever in the UK in 1962/3 when if froze for 12 weeks solid. Since then the wax which used to cause the gelling problem has all but been eliminated from diesel fuel plus additives are added in winter fuel. If you live in extremely cold climates and diesel gelling is still a problem then just add 25 per cent Kerosene to your fuel which will solve the problem, you don't see commercial airline jets having problems with freezing fuel at -50dc when at 40,000 ft but they use 100 per cent jet fuel which is basically Kerosene, putting petrol in one of the high pressure direct injection Diesel engines is Not a good idea because petrol is a spirit and has no lubricating properties in it so may cause very expensive damage to the fuel injection system.
Great vid.....clear and precise. Thanks.
Amazing video. tons of great information. I recently started harvesting 18650's out of old electronics to build a small powerwall.. It's 2 fold. I saved em from going to the landfill, and I'm learning.
thank you for such informative video. really appreciate it.
16:55 - I think that is where Tesla's acquisition of Maxwell Technology comes into play. Tesla can integrate Maxwell's capacitors to capture regen engergy while the Li-Ion batteries heats up to optimal temps.
Skeleton capasitors is future
interesting that in 2020 this topic has only 4 thumbs up. this whole thing is DRIVEN by battery technology - that's why it didn't take off earlier - pitiful batteries. The combination of Li-ion and capacitors opens up a new chapter - humbly IMO. Isn't the final answer, but so much better than anything else right now.
I appreciate the knowledge!!! TY
Great videos both parts, learned quite a lot about Tesla batteries. Thanks for your hard work.
4:24
Talking about density in terms of watts per kilogram doesn't make much sense. Peak power does matter but in this context I think you meant to be talking about watt-hours/kilogram or joules/kilogram. Energy density not power density.
10:28 13,500 Miles / Pear. How many miles do you get per Pear?
Haha yes per year. Sorry
It's always cool as long as you can laugh at yourself.
underrated channel
Thank you so much, very kind of you!
Excellent video love the break down and I love my Tesla!
Great presentation, right questions and answers. Thanks.
I'm pretty sure the Nissan Leaf has at least the option for a heat pump in some years. This video implies that only Tesla's have heat pumps.
Sorry yeah we didn’t mean to imply that. Just speaking about Tesla
Yes, Nissan put heat-pump heaters (like a reversed AC) in 2013 and above. 2011 & 2012 used resistive heating which can only be 100% efficient at best (1 KW of electricity gives 1 KW of heat). Heat pumps allow efficiency far above 1:1!
Lounge lizard, efficiency can never be >1. What you mean to say is that it costs less power to transport heat generated with even more power. e.g. you can heat air with a 3kW heating element but it will take maybe only 600W to move it around.
Edwin de Wit speaking of heat pumps, you can define efficiency as heat output divided by electric input, which then produces efficiency of 300-400%.
@@petrvalkoun4539 that's not how efficiency works LOL
You're right though, heat energy can be measured in watts, but it's nowhere near 300-400%. It's claimed 100% efficient because 100% of the energy that goes in comes out as 100% heat (because we *want* heat, whereas normal electronics heat is undesirable, which detracts from efficiency), however it also introduces wear on the heating element, which takes away from efficiency.. However that heat is then dispersed into the air which can only take so much so quickly (heat capacity) and can only transfer so much so quickly. If you hold your hand to the heater to warm it up, you'll get near 100% efficiency, but any time you add a medium to transfer heat through before it reaches your end target, you're losing heat to it, and air is one of the worst mediums to try and transfer heat.
At 13:47 what you call a AC/DC Inverter looks like a clutch plate to me. One of the many thing missing in a Tesla.
Your incorrect graphics make me question the rest of your story.
Haha yeah we have limited graphic assets and we couldn’t render any more 3D to meet our launch date. We had over 100 hours of rendered content in that video
You have talked me into keeping my 1971 Chevrolet El Camino
Your "el camino" is definitely "the path". The path back to crappy cars.
Thats a classic. Please keep it. I like the way we are going with electric cars as far as helping with the environment but that does not mean ice cars will lose their appeal. Think of the enthusiasts for steam engines. Horribly polluting but such a small number these days that their impact is ignored. The same will happen in due course with ice vehicles. That's progress and it will happen naturally. I for one will be happy to drive my electric car to a race track or rally and drive an old ice classic from time to time.
I wish looking back on my life at 65 now I would have kept my 69 camero/3 bedroom house in San Diego 6 blocks from the beach in PB for 69,000.00 bucks/and big beautiful racked girl friend I had in high school!!
@@jimhood1202 Likely going to cause more environmental damage producing these batteries, already is doing so with cordless power tools
Also major funding ( 30 billion) funding for cold fusion with uranium assistance(pardon me I am not a nuclear physicist) from the Canadian government?
I don't get it!! "little girl save the world" from Sweden the savior to do right, Their country burns garbage and plastic to spin turbines to make power to charge their electric cars! Heat factories and homes!
What gives her the right to come and preach to Canada that we are major greenhouse gas polluters?
She should be sent to India or HOng Kong. Be shot and set on fire.
Little Rich kid hypocrite!
Keep the El Camino!!! will be less polluting burning gasoline!!
Keep it for Sundays...or when you want a horse cart experience.
very good analysis on the cold weather for tesla, thats all the info i need thanks!
Also "in cold temperatures, alot of petrol cars won't even start" what is this, the 1960s? In freezing temperatures (also bad for batteries) contaminated fuel may freeze, causing issues. In freezing temperatures, diesel engines may be disabled without external pre-heating. Also, the line of cars are using battery heaters, like the teslas of the future will need..... Any temperature that is bad for an ICE, is also bad for a motor/batteries.
When I heard him say that I scoffed because I can start my carbureted race motor in 15 degree weather.
then there is russian lada petrol engines that have a rated starting temp of -40c and with some convincing can do -60c , batteries at that temp just WONT work.
I like the idea Tesla Engineers start from scratch if need be instead of piggy backing on existing technology
to save money.
This is costly but can have big leaps forward that were stopping other car companies.
Try creating something then tell us your experience. Talk is cheap.
This sounds more like a Tesla commercial than the "truth" about their batteries. Your dig at gasoline powered cars is proof.
If ever i get the dough to buy a TESLA , i will use your link. Great job guys.
This is a really great pair of videos. Much appreciated. I look forward to an update version in 2020!
Absolutely
This does seem more like a Tesla commercial which makes me wonder about what's being hidden.
Part 3 is hidden
And what is your conclusion?
Hidden a lithium ending and toxic product from tesla/toyota/others li-ion batteries recycling
How do you make the 3d walk throughs? I am thoroughly impressed with the professional quality
I feel like the big hype about the factories polluting more than ever to produce batteries is kind of silly, if I'm honest.
Why?
Well, when we get to the point that there are more EVs are on the road than ICE, wouldn't that drastically lessen the pollution impact than, say, a few factories here and there? You also have to remember, by the time EVs are 60-70% of our cars on the road, battery tech will have significantly advanced. So while the ramp-up might be the most polluting, the long-term goal might be well worth it, yes?
Porsche Duésnburg , please also remember that the Country full of EVs will drastically demand more electricity generation. In the US, electricity is generated mostly by power plants burning dirty fuels like coal, petrol and similar as well as nuclear power plants, which can result in much higher levels of air, water and ambient pollution. Of course there are also many “clean” power plants like hydraulic, wind, solar, etc. but not as much!
@@lucasm8016 nuclear is actually the cleanest of those. Obviously not as clean as wind, solar and water but not anything near as dirty as coals etc.
In a dense area like Beijing, I could see that being an issue. But most of those people utilize bikes and walking anyway, cars there are typically for higher class and/or people who just don't want to be bothered by the garish traffic. Same for NYC, most people down there don't even own a car and just rideshare everywhere they need to go that's out of reasonable walking distance.
So I still stand behind what I said prior. But if I'm honest, I don't think the goal should be to force petrol totally out. Petrol still has it's uses. But drastically reducing the dependency on it would be much better than where we are now :)
Like me, I'm fully onboard with EVs now, thanks Tesla and Fisker. I'm saving to get a Model 3 Performance or AWD LR at very least but not giving up my Datsun 260 and will keep a petrol engine in it. It will be my toy car only once I have an EV daily.
Great job! Excellent!! Thanks you answered most my questions!! Have a great day.... liked and subbed!!!
Great Job!
Thanks!
Does anyone know the efficiency of the model 3 motor? Being a PM motor, it should be over 90%??- Looking forward to your life cycle analysis, i.e. how long you need to drive your Tesla before you've emitted less than sticking with your petrol car. About winter driving: 4WD is really not needed and is an extra penalty when fighting reduced battery capacity. Keeping the battery warm when you need it, is simply a matter of programming your charger to finish when you need the car for your morning commute. That also makes it charge at night where electricity is cheapest.
Yes we’ll definitely get into that
Tore Lund those are all really good points.
These were excellent videos; thank you.
