Why Your Electric Car is Suddenly Making A Lot Of Noise While Parked
Вставка
- Опубліковано 16 сер 2024
- Electric vehicles are known for being quiet and smooth in their daily operation. And with no noisy internal combustion engine, many owners expect them to never make strange sounds.
But in the last few weeks we've heard from a significant number of people asking why their (often new) electric car has started making lots of noise while it's parked and unplugged.
The answer? It's usually something to do with cooling, and hot weather.
Timings:
00:00 - Introduction
02:10 - Why your car is making weird noises.
04:10 - Why batteries need to be kept cool.
06:00 - Why you should keep plugged in.

Best thing about driving an EV on a hot summer day is blasting your AC while idling, without feeling guilty. 😅😅
I still feel a little guilty. I'm still using energy (electricity).
@@kkobayashi1 Electricity production is getting cleaner. So we can get you to the point where you don’t have to feel guilty about using the AC. Thanks for caring about the environment (presumably). 🙂
@@shortfattoad7317 But if you’re walking everywhere, you still have to use energy and resources for your food, home, etc.
To completely eliminate one’s negative impact on the environment, one has to be dead. But most people don’t want to be dead. So it is a good thing for those people to be conscious of their environmental impact while still having a life worth living. 👍🏼
@@RyanWilliams222 you leave a lot of poisons around and cause illness, dead is no picnic either.
Ya isn't it the opposite
I've been opening the "bonnet" on my Bolt when fast charging. The air flows much more easily and the car seems to charge faster. As the temp of the battery increases, the charge rate goes down. When I opened the hood, the fan quieted down and the charge rate went from about 35K to 42K.
Minor inaccuracy at 3:35, probably just misspoken but, it's not an air compressor. The A/C compressor is for compressing gaseous coolant, not air. Most cars don't have air compressors and the ones that do don't turn them on when parked without you specifically using it to pump up tires or air suspension or whatever.
It is neat to hear the A/C and fans doing their thing.. being electric, the compressor speed changes with heat load - optimizing efficiency. With the compressor, the fans also change speed.
Can't wait to see Nikki drive up in her Aptera : .." Hello gang, what do you think?
❤ from Texas
Saved me screaming for help and running in fear from my new Kia Niro. Charging when over 30°c is a new experience for me. Despite the pneumatic drill noises, I am confident.
When you are driving, the fan doesn't have to work as hard since air is being forced in, so another reason you might not hear it while driving.
EV don’t have open fronts though like ICEs
@@santeenl model 3 does (anything with active cooling does) it has louvers that let air in. (I get what you were saying, the inlets are small, but at 30mph, you are getting way more air exchange in there than the fans move)
@@santeenl EVs pretty much all have vents at the front, they are just smaller than ICE car's grills because they don't need to reject as much thermal energy. Saying that EVs don't have open fronts is like saying that a gas lantern has no ventilation, it may not be as open as a camp fire but it still has to have access to fresh air.
Funny thing is my 7.3L Ford diesel does the same thing. Diesel blocks are really thick and after towing with the engine at the correct temp on the gauge there could be a hotspot in the block that slowly radiates heat to the rest of the engine and the fans kick on. Cannot wait for my CT.
Well there's yet another thing for which to be grateful to you!
One of the things which has concerned me about changing from ice to ev is the different noises. From the moment I could sit upright my dad had me sitting in cars listening to the sounds of the engine, fan, gearbox, suspension, anything that moved enough to make a noise. This left me able to tell if something wasn't quite right in any vehicle I drove, I might not know exactly what is wrong with every sound to be able to fix it myself but I'd get a mechanic to look at it. Often they would examine the area I'd point them to, look at me like I'm nuts, pronounce nothing wrong, then a couple of weeks later said item gets to detectable levels and has to be fixed. Although this early warning system is quite handy, now I and my car are old and decrepit it can be quite scary knowing something might be wrong that I can't fix myself or can't afford to have fixed.
Without your hints and tips something like that noise coming from the car would have had me worried. I'd have guessed it was the fan but having it start up randomly would have been puzzling! Thanks Nikki, really helpful item. 👍
I only hear that sound when I open my garage and it is extremely hot outside and I am still charging. I wish there was a trick to activate that cooling system while driving - sometimes I’m slowly creeping behind people walking threw parking lots unaware I am behind them since my PHEV is so quiet.
And quiet electric vehicles are a huge concern to the blind and visually impaired community. We want electric cars to make some kind of a noise so that we can hear it.
@@bardrick4220 I have noticed this as well and it doesn't matterif it's a hybrid or EV, you still have the whir of the motor, gearbox, and other driveline pieces as well as the tires rolling across the surface the vehicle is on. Usually what is weird for me is to hear a hybrid rolling by on the motor, then to have the engine kick in.....oddest was a Tahoe Hybrid, rolled by sounding like a vacuum cleaner then it's LS kicked on with a muted rumble!
3:25 I'd recommend against opening the bonnet when this active cooling is occurring because these cars are engineered for specific volumes of air flow over specific surfaces under the hood and opening it could disrupt the engineered airflow pathways resulting in diminished heat removal rather than the intended "help get more heat out of there" idea.
Aero engineer here; just open the bonnet.
That’s an interesting possibility to consider, but is there any evidence that it’s actually a problem in reality? Extra airflow usually results in more cooling, no? Sounds like something a Bolt engineer-or a crafty Bolt owner-could settle for us!
In a nearby comment, @Jay Suthers said: "As the temp of the battery increases, the charge rate goes down. When I opened the hood, the fan quieted down and the charge rate went from about 35K to 42K." That sounds like hood up is better.
In my new house in TX USA, there is no vents to move the hot air out of the garage, so I had a wall vent added to the garage and leave the attic trap door open. Will be redirecting the laundry room a/c to the garage since they share a common wall.
I had a similar problem with garage temperatures in Utah, but I was able to resolve it my painting my garage door white and adding styrofoam insulation. I still often consider adding some kind of venting, but then I would have more problems with the cold in the winter.
Another excellent piece Nicky. I love your take on these basic issues. Your average car buyer needs this information from the day of purchase but is the manufacturer passing it along in a way where 2nd and subsequent owners will pick up on it?
Interesting side-note: the Bolt footage at 5:55 was taken at River Road across Lamoille River (northern Vermont) about 25 minutes from where I live.
Prove it. You have 30 mins to post footage of yourself dancing on this bridge and send me the link.
My Volt has been running the fans immediately after completing charging this summer. I hear the faint sound of the fans coming from the garage and I know I am going to get the text message
that the car has completed charging. 😊
Great video!!!
I wish I heard more noises from my e-Golf. I just took a trip through the hot central valley that required a few DCFCs and then drove it up a mile in altitude into the mountains. The pack got to 46.5 C. Ouch! Too bad it does not have battery pack cooling.
Funny, I had a similar loud noise in the winter about 6 months after taking delivery of my Bolt. I also had a “check engine” light.
The dealer checked it, couldn’t find a leak, but noted the AC was undercharged. They topped it up and all is good.
You would think manufacturers - especially those who only make electric cars - would see the need for this kind of information getting into the hands of emergency services.
Well done again and thanks for a very important and excellent video
Two things I noticed on my 2017 Bolt which is frustrating to me is after the battery update the car fast charges about %15-%20 slower dropping more significantly the charge speed around 40%. But if that's what it takes to prevent fires I'll live with 15+ extra min waits. The second issue I noticed is the car charger makes NO compensation whatsoever for you needing to use the AC or Heater on charge stations that have no shelter where you can't leave your car. Your AC draws on average 2-3 kW and your heater can draw up to 6+kw.
Now say the charger in it's infinite wisdom decides your battery at around 65% the best rate to charge is 23kW. If your car is not turned off then the charger charge throttler lowering your charge rate does NOT compensate for your power needs and will slow down charging your battery even further. So say you turn on the AC. Even though the fast charger can put out 50+ kW. The charge rate on the battery will drop (using 23kW in previous example) to 20kW because power used from the throttled amount is not compensated. Say you turn on your heater. Now your looking at it charging the battery at only 17kW at the fast charger. The same thing happens when the battery cooler kicks in. It wasn't as noticeable before the update. But now if your in a no shelter charging spot and you need to get to 80% charge for your next leg of your trip the time increase to charge your is QUITE significant with the new software. My previous two long trips at a charger with no shelter in Canton OH it took me around 35 min to get +80%. My last trip needing the AC to keep cool took %54 min to 80%. What is frustrating is the car can and will show you kW power used and the software can control how many kW the charger gives out. But it will still not compensate during charging which makes our throttled power exacerbating the problem even worse. Also stretching out the charge time to power AC/Heat costs a LOT of money when your paying by the min.
You stated that noise from under the hood could be the air compressor. I believe you meant air conditioning compressor. BTW, I bought a 2020 Bolt Premier about 10 days ago. It was a GM Exec car with 6300 miles that had never been titled. Got a great deal!
My 2 year old MX doesn’t do this - so now I’m worried there’s something wrong lol! The only time it sounds like an aircraft gearing up for takeoff is when I set the aircon on from the app to cool the interior down. There is this thing called overheat protection for the interior… it keeps it below 40C… problem is, this feature is not available when sentry is enabled. Bit of a faux pas really.
Teslas do this, but they're much quieter than other EVs. Although of my three EVs, my BMW i3 is the quietest - even the relatively-quiet Tesla is more noticeable. I can only hear the i3 - even if I'm right next to the i3 - if the Tesla *isn't* doing it. But neither the Tesla nor the BMW do it very often.
Good to know, thanks. Which reminds me of the time we heard our mum's 90's Rover cooling down for the first time whilst camping, it would make a sound like a depressed signing duck. My parents assumed it must be something exhaust related, causing this haunting sound, like someone fell asleep playing a trumpet.
Useful to know 👍
As an aside, if it's doing this in an extreme or unusual pattern or far too long, a coolant leakage or condenser failure is a possibility although hopefully not on a new or newish vehicle.
My Tesla Model 3 will often run a fan when parked, even months ago when the temperatures were mild and the battery was cold soaked. Meanwhile, a friends 3 which had just arrived also was doing it. Maybe it was wanting to warm the battery slightly as the day warmed up?
The funny part is that I found that opening the Tesla App on my phone would cause the car to go quiet for about five minutes. This was back in the cool pre-vaccine days when friends were meeting in my shop for lunch with the doors open to the cold for fresh air. We were amused by hearing the car fan start up and noticing that opening our Tesla app would quiet the car.
What the car was trying to accomplish is still a mystery to me, but I suspect it will go away at some point when Tesla figures out how silly and sometimes intrusive it can be. Or maybe they will explain the logic to us engineers that think it's a bug? I'll be curious to learn the logic behind the algorithm.
Thanks for the explanation! This probably would’ve confused me at some point.
Vehicles with air suspension can also make similar noise when compressor runs to keep pressure level up. My MX does that at times
Yeah I remember one of my friends calling me telling me I left my car on when at work one day and I had it charging at an outlet! I freaked out for a second but realized how hot it was that day and figured that was the reason since it usually beeps the horn when I leave it on and walk away from it with the doors shut.
Try parking in the shade if possible on a hot day. 🔥
But 30ºC is not "hot", that's just a typical winter's day, and yes everyone tries to park in the shade on a hot day (>45ºC), if you don't when you come back 10 min later you can't touch the steering wheel.
@@daveamies5031 good grief 🔥
My transport systems make a lot of noise too. Mainly, a loud *neighing* sound :) .
I just had a software update done on my 2019 Bolt. We took the car on a 500 mile trip around Georgia, then went home. When I charged up at home I set the max charge to 100% to see if I had gotten back the available range that was lost because of the last update. My car read 288 miles on the center range and 296 miles on the Max range . And it seems to be holding that range driving around town. Am I the only one that has experienced this bump. I wonder if this was just a fluke or if Chevy has done this on purpose.
in 2017 after nissan replaced my 2011 leaf's battery under warranty i noticed some gurgling noise under the hood when i started the car. come to find out nissan forgot to fill up the coolant that they drained when they replaced the battery. i don't know if that was purposeful to get me to buy a new car sooner. until today, i've only lost about 20% of the capacity to the new battery and zero visit to the dealer for repair. after a decade i still love my first gen nissan leaf like the day i first bought it.
Wow, that was grossly incompetent of them.
Solar umbrellas to shade and charge the car maybe?
I guessed the reason before you reveled it. 😀 Aside from range and recharge times, temperature effects on EV batteries are one of my concerns. Cold is famously not good for batteries. With the heat we've been experiencing in some areas of the country/world only getting worse, I expect manufacturers may have to consider other variables for their products.
Living in Ireland this is likely not a thing I will encounter, but good to know for my road trip next summer!
So in the 80ties me and my mate went in his Saab to Portugal. After parking that car ran it's fan 10 minutes or so to cool down. Nothing unusual to se in Sweden, but people in Portugal stopped us in the street pointing out we forgot to turn off the engine.
I wouldn’t pop the hood if the vehicle is hot and the fans are running, because opening the hood has major impacts in engineered airflow paths. Additionally, some vehicles limit or disable features like the fans turning on with the car off, because they don’t want to risk catching a customer’s fingers up in blades. Some may also turn the fans to high, even if unneeded to make sure the individual is aware of their presence and/or to compensate for interruptions in the airflow path. All of these could limit charging rates and efficiency either due to thermal issues unnecessarily using electricity by running the fans at a higher than normal rate.
Our new Tesla Model Y almost always has constant, unpleasant whine which was not present when I test-drove a MY a couple of months ago. The noise is there even after being parked for hours in a garage with ambient temps in the 70s (°F) or less. It's particularly bothersome when sitting inside the car -- I can't image using "Camp Mode" and trying to sleep with that constant whine.
We're planning a car-camping trip (sleeping in a tent not in the car). But I'm worried the car noise will bother other tent-campers who expect silent nights.
That does not sound right to me. You should check in with the Service Center.
What I was wanting to know is, is there a way to quiet that noise? I understand its purpose and why it's important but can i make that noise quieter or even go away? I'd prefer not to replace the fan but to "repair" or fix it.
I currently just bought a 2022 Chevy bolt EV and there is this whining ac noise when I first start up the car but sometimes it stays on for about 5 minutes when I get driving around or it'll just subside within about 2 minutes. I live in the desert where the current temp is 104 so again this is normal right or should I talk to the dealer about it?
Talking about noise, I notice that my Kona EV makes a high pitch sound, like a squeaky belt from an ICE car, when accelerating and when regenerating (no noise when cruising at constant speed of slowing down without regeneration, so not due to brakes). Apparently other KONA EV owners also noticed this noise. And when we ask the mechanics, they'd say it's normal even though the noise didn't exist in the past. Does this problem exist with other car models? Or anyone knows what the cause is and if there's a cure? Thanks
if you own both a garage and an EV and want to familiarize yourself with the unusual sounds your car makes (hint: sounds that have always been there but heretofore have been drowned out by the slightly higher noise floor of ICE) right pull in and turn on the AC and you will discover the cacophony of what your AC compressor sounds like in operation. the idea of checking it in your garage is twofold, A: you put yourself in isolation AWAY from any environmental noise (so you can actually hear something). B: it gives you the ADDED benefit of amplifying the noise by having it reflect off 3 walls (ref, "fast and furious" kids revving out to hear their exhausts in tunnels). no garage...? no worries, pull into one of those self serve wash bays.
To answer your question on the video that is no longer available, no that was not a rant video, that was an opinion piece and of course it will be mostly personal opinion. In an informational video the information and opinion balance is sometimes too much opinion and if you get 10 times the opinion for one piece of information, that's more towards a rant. This piece on noise, has a better balance than that I feel.
And tastes do differ, this is also my personal opinion and in no way to bring you guys down, I hope you see it more as constructive critique. (hmm, can't think of an alternative to 'you guys' and it feels it needs one)
y'all is a nice alternative to "you guys" that I think we could use more. I'm not sure about the rest of the world, but in the US, "you guys" doesn't really have a strong gender attachment. It can be used for women, men, and anything in between. A lot of people use "guys" to refer to inanimate objects as well. It's extremely flexible. I think referring to the TE team as "you guys" is probably fine, though I'd be interested to hear their take on it.
My 2018 Bolt used to make a 3-4Hz knocking sound before I took it to the dealership for the recall SW update. They said they fixed it but didn't say what the problem was. An internet search informed me it was something to do with the Bosch brake booster. Anyone have more details?
I do hear very faint fan noise when my Honda Clarity PHEV is being charged. I assume since the Clarity only charges on Level 1/2 that the batteries don't generate enough heat to require a lot of thermal management.
I've never owned an EV. I live in the desert, where the temp today was 104 F and the highest we have gotten is 123 F (50 C). Today I walked past a Tesla Model S parked in a parking lot. It sounded like the car was running even though no one was inside.
It might have been maintaining its battery, but especially on a hot day, it's also pretty common for EV owners to set the climate control to keep the cabin cool while going into a store, since it doesn't take much power and the car isn't putting out any emissions as it sits running the AC. Tesla in particular, makes it very easy to do. - Winter
Conscientious excellence. Nice snappy quick take! I hope you do a deep dive on the socio-economic entry prices of EV for a nation that's been wedged into deep stakes gap of the rich and the poor.. Like what is the entrance level to ensure all people can aid in the fossil fuel exodus etc. Much love!
Manufacturers are working very hard to bring prices down. Tesla is leading the way on this, although their cars have historically been expensive. The best thing that poor people can do is drive economical ICE cars until EVs are cheap enough for them. Better still, they could use alternatives like public transport, biking or walking if they are concerned about the environment. In most of the world, poor people can not even dream of owning a car.
My Zoe used to make all sorts of noises (usually fairly shortly after parking). Sometimes the fans would stay on. but other times it made a noise that I never understood but it did sound like a pump going for a short while. I never really thought it something to worry about though.
The pump may be the compressor for the assisted steering?
My Peugeot Partner did that every time I switch on the engine: a quick burst of pumping to fill the air tank.
Another great video.. You probably already covered this Question but anyway.... How long will the Battery hold their charge from say 80% (likely limit of a quick normal charge) and/or 100% to say 50% -"while ecar is not being used". Also would you compare this to 18650 to 2170 to 4680 batt. types...... a nice quick video would be good..
If you here this sound on a normal temperature day get your aconditioning recharge. I had this with an i3 that had not had a recharge for the Aircon in well over 5 years and the recharge solved the issue.
I will never hear such noises. Nissan doesn't have any active battery management in the Leaf.... it's quite literally passive cooling, as in the wind "passing" over the battery pack while driving down the road. Apparently they thought that was good enough. In a few years when I trade up to an Aptera, I still won't hear anything, as the Aptera will be using a passive, albeit, far superior form of passive cooling.
Well that all sounds like a huge power drain. If it's not charging and it's hot from ambient temperature it would require refrigerated cooling, meaning running the air con. Can I drive on a 100F day? Will the Battery even survive in a hot country without constant AC?
You can certainly drive on a 100F day. I live in the northeast US, and have never seen my fan run just from ambient heat. It only happens if I'm charging and it's also hot out. "Hot", in my part of the world, is usually in the 90's though, not triple digits. We make up for it with humidity...
How does heating and cooling a battery while idle affect it's charge percent if it's not plugged in? Has anyone done a test?
It takes battery power, but especially on a longer legged EV, it's not much power in the scheme of things. I don't know if anyone has done a test though. - Winter
Are they also supposed to keep warm in sub freezing weather? Because they're still making noises in the middle of winter
Okay. I give up. How does one "pop the floor" of an electric auto?
Could the waste heat from the car batteries come to use? Maybe be tapped into the district heating system?
It's not enough heat to make capturing it economically worthwhile.
"when the temperature in ºC starts with a 3" so a typical winter day where I live 😟how much power do they use to do this? I guess if I get an EV I'll need to install shade sails where I park at home and try more diligently to park in shady car parks, though 35ºC is not uncommon in the shade in the summer.
Shouldn't be too much. Heating in freezing temps is much worse, as most EVs use very inefficient resistive heaters. Generally the newer a car is the better, because heat management systems evolved rapidly in recent years.
Shade is good in general as UV light slowly destroys many materials, plastics for example.
Our LEAF - should we keep it in the shade whenever we can?
In my experience, the 24 kWh's battery does not get hotter than ambient temperature, when parked in the sun. So i think it doesnt damage the battery. But, the shade is more comfortable!
My 2017 Bolt EV hasn't made any unusual noises, even in 92°F weather the car isn't losing any excess energy day to day either. Only time it makes the noise is when the car is fast charging for at least 20 minutes.
Where is the bonnet?
Is this part of a series? It’s very concerning when you are first time EV driver and you hear clunking underneath your feet when you are driving up a mountain for our charging in the middle of the night and it’s very cold. Isn’t that clunking sound from your battery opening or closing electrical circuits?
When my Tesla starts pre conditioning for supercharging, the fans start. Doesn't matter if it's hot or cold. My car is always the loudest car at the supercharger, sound like fans are running full speed all the time. I'm sure if it got checkout by Tesla they would say it's normal. But it's quite bothersome.
If you navigate to the supercharger, it will precondition on the way. Are you noticing this while driving to the SC, or only after you start to charge?
@@incognitotorpedo42 after about 5 min of pre conditioning the fans start regardless of whether I have arrived to charge. That's what's puzzling.
Because it can !
i am looking at a getting a BEV but they feel odd. I have been driving SUVs for almost all the time from 1996 until today. any tips how to get used to being so low to the ground in a BEV that is so low rider like.
They have the cross overs which sit a bit higher but I agree swapping between my pickup and Volt is a bit weird for the first couple minutes of driving.
You could try making some quick turns or slalom moves. It may not make it feel any less weird, but when you experience the confident handling and quick response that comes with a low center of gravity, you might decide it's worth the weirdness. You do get used to it though. Felt kinda weird the last time I drove an F250, so I know what you mean.
"Don't worry, your EV is just about to blow up" 🐣
2:45 “your car *isn’t* about to blow up”
This is going to be an interesting issue here in Australia as we get more and more EVs on the road (yes we will) because summer temperatures in the mid 30s to mid 40s (Celsius. Equates to 95 - 113 F) are common. I can’t wait to hear what people say when the asphalt in an open air commuter car park with a few dozen EVs in it hits ~50 C on a summer’s day (yes that happens)….
Yep I always thought the whole temperature thing is going to be a problem, actively cooling the battery in hot countries and actively heating them in cold countries whilst just sitting not driving is bad as it not only means your range will be less but also its using energy to do nothing at all, if its left for long enough not plugged in you have a flat battery maybe permanently damaged too.
Needs solar umbrellas to shade the car and keep the battery charged maybe..
@@ronvds4713 I was thinking 30 or so would be enough to give you ~50 and screaming fans…
@@FlyingFun. The launch versions of Hyundai’ Ionic 5 have an optional solar panel roof which is apparently good for about 200 W. Be nice if a few other manufacturers picked that idea up as it might be enough to run the cooling system on a hot day.
Yeah, this is good to remember, the hot asphalt has stored all the heat from the sun and the battery will help to cool it when you park over it. Maybe a heat shield is needed. My friend was driving around in Tuscon, AZ with a plywood sheet on the roof. The roof got so hot that it was trying to fry his brain.
Good to know
I live in Arizona where normally in the summer we have days over 114° Fahrenheit or 46° c. How much power does the cooling system use? Is it enough to cut down your mileage?
You would probably see better mileage in winter in the desert than during the summer.
An AC compressor will fluctuate from 500 watts up to 2,000 watts (ballpark). So a 70 kWh battery (70,000 watt/hours) would consume 10,000 watt/ hours after 5 hours of driving. (5 hours × 2,000 watts = 10,000 watt/hrs)
To sum it up, after 5 hours with the AC blasting on a very hot day, just under 15% of the battery....or a 15% reduction in range over mild day performance.
@@wzDH106 it also worries me about the translucent roof. I wonder how much heat it lets in. And if that would affect your calculation.
@@jayfromaz
Well, I calculated 2,000 watts constant. That's quite a bit of power and would be considered worst case just to give an idea. I can't imagine anything higher. Our Kia e-Niro tops out at 800 watts.
To put this energy in perspective, 2,000 watts could potentially power two window AC units, or the central air conditioning of a small house.
@@wzDH106 thank you very much. I really appreciate it. There's so much to know about this new technology. And hopefully one day the batteries will be far better and less the laws of physics kick in and limit that progress.
@@jayfromaz
Correction on our Kia e-Niro AC usage. We peaked at 1,800 watts periodically yesterday during this 110F Pacific Northwest heat wave. The additional cooling was most likely for the battery to keep it below 90F (battery temperature). We had the cabin set to 65F.
Out driving efficiency (with AC running) was still estimating 280 miles, but still slightly lower over mild weather 60-70F days where efficiency estimates usually push 300 miles on the same drive.
We never get this kind of weather here, thus not requiring battery cooling. But it's a good data point for this conversation.
Our IC engine also makes such noises after engine has been shut down. From hot hot India
I drive a Renault Zoe 2016 model that never had this issue, until I got a new motor a month ago. But I still have no idea why it's happening, cause I live in Norway and it's FUCKING COLD here! Like a negative 2 celcius today. 🤷
So, we’ve never heard this from the Nissan Leaf. . . 😀
yea, because it has no cooling system. R.I.P. Leaf battery packs...
My Mazda 3 does this ^-^
(Makes loads of extra noise while parked trying to cool itself)
My Mazda 3 used to do the same, but only for an hour or so after a drive. It’s still odd to me when one of our EVs does this even when it hasn’t been driven in a couple of days - Winter
The answer, you'll be pleased to know is that your battery electric is wasting energy that fuel cell electric vehicle never need to waste. It always happens to BEVs in the winter as well, it's just that it's quiet.
With fuel cell vehicles that energy is wasted long before it even gets to the car 😉
@@EternitP8 nonsense, green LH2 production via SMR is 70% efficient and batteries are less than 20% efficient at that phase (batteries have already lost 80% of the energy before the cars battery is even charged).
@@homomorphic How do batteries lose 80% of the energy? Are you talking about Carnot inefficiencies at fossil fuel plants? My energy supply is clean, so Carnot doesn't apply. Transmission losses and rectifier inefficiency is much much lower than that.
@@incognitotorpedo42 no, they lose that because you can't possibly construct enough batteries to accommodate the seasonal variation in renewable production (which for the US is in the terrawatt-hour scale). Hydrogen, otoh can easily accommodate that amount of storage so by comparison is able to capture nearly 80% of the available renewable energy while batteries can only capture a small fraction of it. Essentially batteries send enormous amounts of renewable energy to curtailment, which means that you need to build renewable generation for maximum seasonal demand and then waste the generation during the minimal seasonal demand period.
My stomach does the same thing.
It's definitely NOT an 'air compressor pump'. Might be an air conditioning compressor...
*cries in Leaf battery degradation*
find it odd how often my car is being noisy while parked in my garage - it's not hot in there! Not bothered by it, just surprised.
If your garage is closed, the more your car tries to cool itself down, the hotter your garage gets
👍👍😎✌️🤟
Explainjng this is sooooo tiriing
Blow up? More like blow off😋
Love the pride design shirts!
I’m going to keep my ICE.
I found the introductory speach to be a demonstration of arrogance and quite condescending. It does not demonstrate experience or professionalism
Too long for such a simple thing.
Maybe it's time to consider battery swapping like NIO.
Battery swapping is a horrible idea for a lot of reasons.
