10 minutes....To boil your very expensive battery.....and shorten its life...🤔🙄🙄😏🇬🇧
Batteries aren't greatly affected, but some other electronic components do suffer a shorter service life if they're frequently subject to high temperatures - primarily capacitors.
you are correct Like cold, heat can destroy your battery life. In fact, high temperatures can cause an explosion. Lithium batteries lose their capacity faster at high temperatures. Thus, overheating reduces the battery's cycle life.
@@stanmarcusgtv agree , but less with fire. Fire is because a defect of manufacture ( bad cell, wires, electronic )
Like gasoline. Blame is not gasoline when ICE car is on fire, blame is pipe that leaking near hot engine. Why you are not worried with your gasoline under the car ?
@@stanmarcusgtv high temp of battery cells if a blame of engineers fault because they don't add termal management sistem becouse of cost/ greed
Because, all battery cells are created equally in your informed mind?
Tell the driver of an original prius that it takes his tiny battery an hour to charge, for it not to degrade after a couple hundred cycles.
The upgrading of the local grid to handle all the current being drawn, would be insane.
Charger will have a local battery to not destroy grid if can't hold that. I'm sure of that.
Not just the local grid, but everything all the way back to the power stations and coal mines.
@@eunu6928 That battery is going to need to be massive to handle peak usage, and it'll still need to be charged.
Things like this happen over decades, no need to panic young padawan.
@@Stormcrow_1 do you think grid operator approve this station if can't hold it ? :)) is his loss if something is happening on the grid. Lawsuit will bring operator bankrupt.
Approver is not a joke.
These EV car sellers will stop nothing to get cars off the lot , they must think we are all stupid .
Nicely pointed out John .
Unfortunately most of the public are..... Bonhoeffer's law of stupid
I live about 100 miles or 160km north of Miami near Florida’s Atlantic coast, and whenever I drive anywhere around here there’s a Tesla in front of me or using the same parking lot, guaranteed, at least once in every trip. Not everyone here is a rich fool, but we have an excellent supply of them.
It does sounded like a desperate pitch to get financing to keep the light on.
There is still an alarming portion of society that believe EV’s are environmentally friendly… so YES, there are morons walking amongst us everywhere!
@@markiangooley The point of your post is what🤷🏻♂️ are there too many Tesla’s or possibly the fact that there are 100times more Ford F150 trucks just what are you telling us.
Tiffany… the only ‘pole-star’ I really care about 😏
Make sense
I watched a demonstration of some fancy new super charger where they said it could completely charge a battery in 12 mins. It took 18 minutes to go from 20% to 80%. Back when I did maths that would be only a 60% charge in 150% of the claimed time. But the EVangelist presenter was making out it was an amazing new leap in EV ownership.
New~ish. This one does 7 to 80% in 11 minutes: ua-cam.com/video/Sf9P-jdla6U/v-deo.html
in the head 20%-80% is fully charged ..
@@LevyHappyClapper If you or the stupid on board computer which allows you to voluntarily let your battery go below 20%, or above 80%, the Nissan 5 year battery warranty is void. £5,000 for a new battery please Sir. I speak from experience. . . .and how do they stop the battery from superheating (and therefore self-combusting) when they are pumping in electricity from the next door nuclear power station at such a rate that they have to lower the cooling rods to full depth?
It depends on the charge curve of the particular car you are charging, the station could do it, the particular car might not be able to
People are stupid, they don't understand what a charge curve is. ICE is for dummies.
So, what you are saying is.. in a scenario where we are in the midst of a cold winter (Uk based) where fuel resources are limited either 3 Polstar’s can charge or alternatively 100 homes are heated?
If you use the same fuel source for both, yes. How many homes still use oil or gas heating? 🤷🏻♂️ But even if people are save with their heating, imagine people want to cook or use their washing machine or dryer. I’d say, they will have to build a separate grid just for charging
@@tarwod1098 no need for separate grid, just double the current one to support the cars. and triple it if you want to push all the heaters and ovens and such to electric too.
I am unfortunately in public housing, so the bottom of the energy heap. I receive frequent cheery calls from solar companies, which leave me alone as soon as they are made aware of this.
Yeah, you wouldn't want to make additional profits off otherwise unsused roof space
Unfortunately many of those cold calling solar panel selling companies are basically running a scam. They had my FIL thinking it was a good deal putting more than 40K worth of solar panels on his home to save $50 a month on electricity with this huge financial costs later down the road.
Fast charging destroys the stupid, expensive battery even faster. Filling up your hydrocarbon car fast doesn't harm anything.
Excellent point.
Depends on how well the engineers have done with the battery management system. Tesla batteries likely to outlast most Toyotas even when exclusively fast charged. Other cars (looking at you Nissan) not so much
@MrStephendowns Electric utopia. What about the extremely poor resale value of electric cars? They're not worth it, by any stretch of the imagination
That can charge in 10minutes occasional (1time/month) is not a big deal with a good thermal activ sistem. Indeed, can degraded it if this charging is do it everyday.
But don't need to worry, untill now the rare biggest charging station is 350kwh , that means can add only 60kwh in 10minutes :) indeed impressive.
@@BubblesTheCat1 Hmmm. What exactly does this mean? Some companies like Tesla and BYD are getting better at making better EVs at cheaper prices while making a profit than legacy automakers who are making losses on their inferior EVs at higher prices. This does have the effect of lowering resale value. You seem to have the same perverted way of thinking as politicians who don't want to see house prices become affordable since than would lead to "Losses" for speculators.
EVangelists don't think in terms of KWh. All that matters to them is minutes and horsepower. A guy replying to one of my comments recently stated that his EV could give out 1050 hp. He believed that hp is given for free and has no connection with the current being drawn from the battery. Another informed me he could do 4000 km on one full charge. I'd love to know what it's like living in EV wonderland.
1050 hp = 783 Kw.
I'll have what they're SMOKIN' !!
I think its time the LDeVMGT+ ev collective got its own flag...suggest Icarus flying on a solar panel on a fire orange background.
What about a flag for cars that were “assigned” internal combustion at birth, but decided to transition to electric?
Excellent

@@taxus750 Is that really a thing? Never heard of them.
Amen brother / or sister ?
What they don't advertise is that charging fully is not good for battery health. Yet same time they advertise range fully charged. Good that new batteries are better in this regard.
exactly! rented a Polestar last year and the car says don’t charge more than 90%!
It is fine to take your lithium ion battery to 100%, as long as you don't leave it there for days, weeks or months. Same with taking it near zero. It's not about not doing it, it's about leaving the battery at very high and very low states of charge for duration. Lithium iron phosphate batteries are not affected by this. The 20-80% guide is increasingly being mistrepresented, as we now seem to have past peak fire myth.

Here in Canada they started putting solar panels on all steel farm buildings in a government program. Early on the insurance company's would not insure anything parked inside these buildings. They even stopped insuring livestock inside the buildings due to electric discharge in the buildings.
Hmmm amazing thanks for the update
I don't care if an EV charges in 10 seconds, I aint buying one.
If it can charge in 5min, offer 1000km range and cost less than 40k new with all bells and whistles, I'm buying one.
Oh, and DC chargers have to be cheaper than gasoline of course.

And even with Tesla, where are the new batteries that they said were coming from Maxwell, the company they bought 4 years ago? It's just all flim-flam every time.
And if Maxwell themselves had a world-beating battery technology, how come the whole world of EV wasn't querying around the block to buy their tech? I'ts just Musk crap pushing the EV mantra, again.

Despite them lying - it is still significant progress. I have 80w charging on my phone and I really never have to worry about it going flat as it takes about 10 mins to charge it 60-70%. I imagine this would be as close to a game changer for EVs as could be hoped for.
Id be more concerned about the feasibility of the infrastructure. That is a shit ton of power draw.
True
Why do people always go on about a phone? Your phone uses almost no power in the first place and you're highly unlikely to ever be more than a few steps away from a power source with enough output to be able to throw however much current it could ever take at it.
If an ev used very little power and was always in the same room as a power station it wouldn't be a problem either.
As I understand it, you're not supposed to quick charge often as it degrades the battery. You're also not supposed to charge over 90% or discharge lower than 10% for the same reason. But occasionally you need to charge to 100%. So you really don't have more than 80% of the advertised range even when it's new.
Thanks John once again for pointing out what real environmentalists and sensible thinkers have been saying for years. There will be no such thing as an EV utopia, life will not just go on exactly the same just with EVs instead.
No if we actually really face facts life will have to drastically change. We’ll need to live closer to where we work, work more from home, use public transport, use active transport, have much much smaller cars and learn to live with less energy. Electric cars are just the same path to destruction as everything else we do at the moment.
10% to 80% in 10 minutes???
From an engineering perspective this seems too good to be true….
And if it seems to be, it usually is.
It is too good to be true. It might be alright to fast charge like that once or twice under laboratory conditions. But not under normal everyday conditions. It produces a lot of heat that could ignite the battery. And it drastically shortens the life of the battery if you do it regularly. And we haven't even started to talk about the impossibly massive power grid needed to charge a a fleet of EVs like this.
You're utterly uninformed for an engineer, from a non-engineer's point of view.
In batteries, it's cheap/dense/fast, pick two!
This trade-off bound to improve forever until some minerals get banned for "science is settled" reasons.
How fast do you think hybrid car batteries can do the 10-80%? It takes all kinds.
Do they cool the charging connector and wire with liquid nitrogen???
@@Cloxxki You also need one heck of a supply of current to charge an EV battery to 80%.
EV are for people who understand neither electricity or chemistry... or the insatiable need of governments to make money out of motorists, EV really are on honeymoon at the moment and EV drivers really think that will continue.
Trying to stuff a quart into a pint pot in a short time period = heat. Batteries much prefer trickle charging, the longer the better. The idea of stuffing all that energy into a battery in a few minutes spells disaster.
You need to hook some cable up to the clocktower and wait for a storm.
"1.21 JIGAWATTS...!!! GREAT SCOTT...!!!" (Doc Brown slaps hand on forehead)
Rapid ludicrous accekeration is such an energy saving concept. Let''s have our cars accelerate three times faster across the fleet. That should save the planet. Regenerative breaking, that will get it back, right?
*braking
Power. We have to have POWER and ACCELERATION at all costs. Let's put a 300hp EV with absurd torque in the hands of someone who's only ever driven 90HP ICE and see what happens - but we must have more POWER because that's what people want, certainly not cheaper, more eco cars with smaller batteries to use in cities, because in start/stop traffic we need to be able to accelerate at 0.5x the speed of light - don't we?
Braking, not breaking FFS.

And I was wondering what comedy I was going to watch tonight after your 2 part laugh fest miniseries. Keep up the good work.
In the southeastern USA, where I live, only 30% of rooftop solar systems installed are still in service. Most of them were giant, rip offs, and most of the companies that installed them are gone. So those people have to rely on other third parties to keep their systems operational. At the end of the day, their cost of power when you factor in the cost of their solar system and the outrageous cost of maintaining it has doubled. That is why so many of the systems have been decommissioned. Rooftop solar reduces the resale value of your home. It also drives up your insurance cost for homeowners insurance. If you want to install solar do it with ground racks away from your house you’ll still probably lose money in spades, but you won’t have a leaky roof.
America is totally different to Australia. Most of those issues and downsides don't exist here. Though we also have fly by night installers that are no longer in business when problems arise. Your leaky roof problems are down to the US not moving on from wooden sheet goods covering the trusses, then a supposedly water proof membrane on top of that, and then shingles. When they don't use shingles and install some form of corrugated iron instead, the industry over there dictates and insists the Tek screws be fixed into the flats rather than ridges which is the exact opposite to how most of the rest of the world does it. Undoubtedly they do something equally wacko and fix mounting brackets for the rails through everything with a Tek screw, then put a bit of silicone around it in hopes it wont leak and call it a day.
I think you got this wrong, with all due respect. A normal user would normally charge the car at home, overnight, at low speed, when the tariff is lower and causing the least damage to the battery. For most commuters, they need to do this weekly or even biweekly. The battery will easily outlive your car.
Fast charging would only be required during the occasional long trips. And the capacity to add 500 Km more range in 10min and continue your trip is not bad.
Let's face it, you cannot drive more than 3-4h continuously. You need a break. And in this time you hardly make 500km road. This break is already enough refill you another 500 km and you're good to go.
If there will be more EVs you will be charging 10 mins but first waiting 3 hours in cue to the charger if you will lucky to find one working.
Charge it with coal at night when the sun's not shining?
@@Frostyfruit2 Wind still blows...
It is the unknowable state of an EV battery that cans their resale value; it could be good, or on its last legs...
It is the unknowable state of an EV battery that cans their resale value; it could be good, or on its last legs...
What annoys me is that you can point out the flaws in EV technology right after talking up solar roof panels and home batteries, knowing full well that the total cost of ownership including installation, maintenance and eventual removal and roof repair makes them a bad to terrible deal.
🤭 A little hypocritical, isn't he? I think the home solar people are sponsors, so all is good with their system.
Can't help but wonder what'll happen if an ev manufacturer were to offer a very good sponsorship deal...🤔🤭
Nobody mentions installation and maintenance costs, just that you could save money - eventually. Maybe in about 10 years you might break even. Possibly.
@tonyb3629 And then you'd have to replace batteries and perhaps even panels. So, the costs are always there.
The only place a home solar system makes excellent sense is here in Sat Afrika, where the grid is extremely unreliable due to incompetence and corruption. Here, a solar setup is a very nice to have when there's no power for 8 to 10 hours a day.
What are you driveling on about? who buys solar/batteries and installs it themself, off course it includes installation, as for maintenance, my first solar panels lasted 11 years with zero maintenance, removed for zero cost when I upgraded them and added a battery. 2.5 years latter = zero mainenance. Roof repairs if I remove is 50 roof tiles from a salvage yard Ouch maybe $150 in 20 years. Solar in AU pays for itself very quickly, batteries not so quickly but I haven't paid for power in 2.5 years since getting a battery and have pushed enough power back to the grid for another average two AU houses usage. Sorry for being so green and reducing my Co2 foot print. Still wouldn't by a 100% EV, maybe a hybrid or plugin Hybrid.
@@cam_934 Toyota makes excellent hybrids 😁🙋🏼♂️
Getting the claimed range would reshape the landscape. You only have to fool some of the people some of the time.
A local hotel developer apparently did apply to install 20 chargers @ 350 kW/h but authorities declined to engage with him.
Uh huh. And tell us how many times you can shovel electrons into that battery at that rate and how long the battery will last if you do…?
No one has mentioned that the school, bakery, hospital , hamburger shop all had to shut down their power to supply one car the hundreds of amps to charge one car .
As an engineer, even years ago all this EV stuff made me go- wait- what??? You'll need welding cables and tons of power to do any of this. It's not possible. Indeed it is not. Well possible perhaps, but certainly not practical.
Wow, a company that in 12 years has failed to deliver a single promised technology and no commercial products??? Seems like a waste of money, bet taxpayers are footing the bill, no way investors would touch that steaming pile of horse sh*** with a one-mile pole… 😂😂😂
*John, I suggest you watch SerpentZA's report on Chinese EV's*

You can also watch _China Insider with David Zhang_ on his report into China's EVs (including one owner that thought he was getting haemorrhoids) and how the CCP authorities deal with victims of EV incidents. 👍
We recently went to a farming field days. It occurred to me that day that there were 2-300 cars there, many from a couple or more of hours away. So likely short of petrol/diesel before the trip home. So the day ends and everyone leaves at about the same time, many stopping at the first garage on the way home. It will be an "interesting" experience when everybody goes electric. There's going to have to be some serious changes somewhere along the line before that happens. Many events are going to be similar to this.
At the rate they're shutting farms down there wont be farming field days or other big rural events to attend.

Using a truck hose i fill my 40l i30 diesel in 30 seconds. Full stop/ gone time slot 75 seconds
Even normal pumps are between 50l/min and 80l/min so most tanks will be full inside a minute and not much over for large ones.
I timed my car empty to full (40l tank with the light on) and it took 34s from pulling the pump to it going click.
My minibus (100l tank) took 1:12 with similar conditions.
From car stopped to ready to go is always under 3 minutes unless there is a queue to pay.
Assuming they could lock in a game changing battery in 3 years, who the hell would buy a soon to be obsolete battery now? Resale would plummet., therefore people shopping for a vehicle now would expect massive discounts.
Here in NZ Vdub already took 20% off their prices. Can't do that too often and keep your head above water.

If EVs were about climate
then there’d be far more workshops specialising in ICE to EV drive in drive out conversions……
But its all not about climate
It’s ALL about money………….
Sell em the most expensive option….
If it were about climate, we'd be driving cheap biofuels for decades now.
Except you're wrong. The fact is that EV conversions are MUCH more expensive than buying a new mid spec EV.
The late Jack Rickard ran a conversion shop for many years doing just that (well before Tesla came along).... He openly stated he could not convert a vehicle for the price Teslas were selling for (to deliver a similar standard of vehicle). He made plenty of videos and they are all well worth a watch (if you have the time): ua-cam.com/video/Wv_XcxpRuTw/v-deo.html
A megawatt is about a third of a large wind turbine' output. What that means in your neighborhood, I don't know. Sounds like some pretty thick wires would need to be strung up.
300kVA final zone transformer good for 40-60 houses with typical demand using in modern homes
so the typical village gas station with four pumps needs 32 of them if everyone is driving BEVs.
(takes roughly four times longer to fill up a car to 100% than with a pump and you have to do it twice as often as the range is roughly half)
Nr. 33 is then used to power the rest of the village.
You don't have to imagine very hard to see how a charging station with 100 chargers is built and connected to the grid.
Now these aren't 350kw each but there are enough of them that you can extrapolate.

Hi John.
I have a question about new car warranty and diy servicing.
I have a '22 Mit Outlander.
I get the regular 15k km service at the dealer to maintain the 10 year warranty.
I'd class my car usage as excessive by Mitsubishi standards and think I should do the engine oil every 7.5k or 6 months.
If I do the oil change myself between logbook services. Do you think Mitsubishi may take issue with it or deny a warranty claim?
Cars are 400 volts
Buses are 600 volts. 3 phase 32amps each. Imagine the power bill
Bit of a pathetic walk-back from the last video.
There are valid critiques against EVs, but this is not one of them (but see below). For road trips, NMC batteries always had a real-world 80-10% usage range, nothing new. For my Polestar 2 MY2024 , it means a real world range in summer (it's when I do longer road-trips) of around 400km / 250 miles. In fact, 70-10% is even more optimal on a road trip as would take only 20 minutes, which is a welcome break and time to buy a coffee every third hour. For everyday usage, I and most EV owners never use public chargers anyway.
- A valid critique would be that governments pushes people to buying new cars by increasing taxes on ICE cars and giving limited time tax cuts on EVs. Yet, the carbon footprint of manufacturing a car (particularly an EV) is much bigger than the total carbon emission from an average ICE car during its lifespan. So if governments really cared about global carbon emissions, they should make incentives to keep ICE cars as long as possible, not the opposite.
But imagine if everyone were driving those electric sh*tboxes, how long would you be waiting in line.
If Australia can't make EVs feasible, what hope for elsewhere. The point of EVs is that they can be run from renewables, not directly reliant on fossil fuel. Is there an ethical/ecological/technical/economic reason why 'the Australian interior' is not filled with solar panels or is the Australian weather not as sunny as reported.
70% charged in 10min, that’s faster than my iPhone 15.
The trouble is, any publicity to get brand recognition always works.
The more we talk about Polestar, the bigger the brand becomes.

They are not to be blamed on an individual level. Their government and members of the IDF should suffer consequences for their actions, individually.
The system that gives birth to the indoctrination of the people in Israel, the imperial forces that fund it, and the various declarations, pacts or agreements which led to the creation of Israel are the blame.
You can't solve the problem without critiquing the system.

bingo, like so much Investment Prospectus, it's always just a bunch of "propositional" and FORWARD-LOOKING statements being made (most of which are completely divorced from reality)...
I guess the hope is that most will simply be too dumb to see the technique, too dumb to see the pattern.
Isn't there a cap on how many fast charges you can do, in a row, before you have to do a 'slow' charge? This means that if I want to travel from Melbourne to Brisbane or vise versa, which I have done in the recent past, I have to have 2 overnight stays per direction, somewhere where I have access to a 'slow' charger? Wouldn't we have to get over that hurdle in our wide open spaces of Australia? Or do we do what the Norwegians do and have a EV for city driving and ICE for long distance driving?
Others have tested the Polstar's cars and have one huge problem bad internal stuff that are slower then your first computer in 1984! So many problems they call the wise car on 2021-22!
Victoria BC Canada will allow EV owners to string a cable across the public sidewalk to charge their junk out on the street!... can anyone see a problem with that??
Billions is being spent now on battery R and D . The money has vanished from fossil fuel R and D.
They've already told us that fast charging is bad for your battery, so why is fast charging even a thing? Are people just supposed to shut up and accept accelerated battery degradation as a normal part of EV ownership?
Australia's car industry is confined to R&D where they used to produce up to 400,000 cars per year. If you embraced EV technology you could be producing EVs, be part of the supply chain and recycle them too. As you rely 100% on car imports and ICE production will end by 2030, you have no choice but to go electric.
No it isnt underglow, i just charged the battery.
LMAO...👏
My first thought on looking at that photo was look at the gauge of the charging cable, how many amps are they running through that to achieve their magical charge time?
I put 15kw of solar on the roof with a 28kw battery pack and bought a brand new toyota hybrid. Combined I was still 20% under the comparitive EV cost+charger ect . I'm sure I'm doing much more for the enviroment and I can drive my hybrid anywhere for as long as I like. The battery back up solar is the best money I've ever spent.
I can see the need for 10MW or more of local battery storage at each bank of chargers to do this kind of charging without fritzing out the power to the local town. Batteries charging batteries. How many extra power stations will it actually take to sort the problem? Is ANYBODY actually building more generation capacity for ev's?
No one ever thought this through, surprise surprise.
Are they going to give free wheel alignments after each 10 recharge? The way the battery will start to distort will effect tracking, the'll need it 🤣
And as for back up batteries for your solar panels , remember if you go with Lithium, 30% of the grid sized batteries installed to date have spontaneously caught fire .
A li battery fire is every bit as problematic bolted to the side of your house as it is under the bonnet of an EV so if you go with Li have the battery installed remotely .
Flow Cells are AFAIK the only safe back up battery but they are expensive .
However they will last forever and do not loose capacity with age .
OTOH I have seen a few people who posted they bought an old EV for less than the price of the same capacity household storage battery and used it to connect to their solar cells
Hello John

The issue of supplying enough power to large recharging stations would be another order of magnitude worse if we adopt electric long haul trucks.

Excuse my ignorance - what are the volts / amps that line up with say 350 kW EV charging?
To avoid very heavy change cables, the volts MUST be well up there !
You admonish Polestar for “lying”, and there YOU go (again). The Tesla Supercharger V3 - 250kW chargers - the largest site of which is 84 stalls that can run simultaneously, do not draw directly from the grid, they buffer through a bank of Tesla Megapack batteries. A Megapack can store up to 3.9 megawatt-hours (MWh) of electricity. That site (Quartzsite, Arizona) also charges its on-site storage from solar panels, topped up with off-peak electricity from the grid. Why don’t you do your sums on that?
Was "Kwick Fast Charging" already taken?
I asked this on your last video and I’m asking one more time in hopes John sees it. Would many of your points be mitigated regionally in areas where power is produced by nuclear or hydro? Is there any point where EVs make more sense environmentally over ICE given more regional differences? Or is EV only a bad choice no matter the situation?

This bit's got me thinking of, wotsername - Lizzie Holmes.
Almost nothing couldn't be done with that spot of blood.
This is such a non issue with Teslas. 90% of the time we charge overnight on a 110 volt outlet and gain 40-50 miles- enough for the next day. We drive our Tesla from Florida to CT several times a year There are many dozens of charging stations along the route. We generally charge to 80% and drive for 2-21/2 hours to the next charge station and have breakfast or lunch. going from 5-10% to 80% max. This takes 20-25 mins in our model Y.
Usually not enough time to enjoy our meal or go to the toilet. So charging is never a problem.
Usually this is
enough time to finish our meal! meal!
How long do you think the battery will last, charging that fast.
While a 60l tank will still hold 60l after 10 years, that 5l/100km engine sure as heck will consume more than 5l/100km after 10years...
Really? Funny that. My 1990 Daihatsu Feroza took 53ish litres for 540ish kms from new to 17 years of age. My 2002 turbo diesel Hilux burnt 10ish litres of diesel per 100kms from new to 18 years of age. My 06 TDI Golf maintained its fuel consumption over its 11 years from new til its sale. But every rechargeable battery powered thing I have ever owned has had severe battery life degradation be it lead acid, nickel cadmium, nickel metal hydride or lithium.
@@rachels209 you are correct, that the differences sure as heck are smaller. But every study I've seen so far has pointed at measurable consumption increase over time (that is, until major engine repairs)
And have a look at the Qilin battery from CATL very fast charging, 5C charging rate
That means 12minutes to who don't know ;)
Plugin hybrids with small batteries are the optimal car technology. You can drive just on battery for the daily commute, then switch to petrol for road trips.
Dude, change the battery in your smoke alarm!
The faster you charge your battery, the faster its performance and capacity will degrade. Sounds like a great move for the manufacturer and not such a great move for the consumer or environment.
The whole EV thing is being done wrong. Batteries should be standardised and exchangeable. Along the lines of the swap and go gas bottles.
How long before the solar panels are in land fill 🤔🤔🤔
Is it true the typical australian home only has 50 amp service?
From 10% to 80% is a 70% charge
The first 70% of a recharge is the dead easy bit and the fasted bit
It is the last 30% that takes forever & a day
I would imagine most EV's would charge to 80% capacity fairly quickly
The more complete the charge the greater the resistance to recharging
And this has been the case from day 1 of rechargable batteries and this is regardless of the battery chemistry
I always explain it with the air compressor analogy ( which is a lot closer to true than most would think )
Turn your compressor on and you hear it pumping away at full bore but by the time it is 1/2 full you can hear the motor slowing down as the pump has to do more & more work to force the molecules of air closer together .
Well the same goes for batteries the charger is forcing electrons to migrate through the electrodes and a reaction to reverse
Electrons naturally repel each other so the more you force in the more they resist
But do not believe me , search for battery charging rate graphs and you will see the are all rectangular hyperbolic curves or because they usually have percentage charge on the vertical axis and time on the horizontal , inverse rectangular hyperbolic curves with the charging rate near vertical at the beginning then going through an inflection curve to be near horizontal as you approach fully charged .
And funny enough the point of inflection between charging quickly & charging slowly is generally around the 70% mark for most batteries .
So Polestar has just reinvented the wheel ?
The way I see fast charging is. The more you pump in the less life you will have. And the more chances of fire.
There's none problem to charge a Lithium-Ion battery from 10% to 80% in 10 minutes, some smartphone do it.
That's called a 6C charge, at 6 times the recommended speed and electric load. It works well.
But it will shorten the battery life expectancy dramatically, that's what many people actually observe when they used fast chargers on their cars, and that why a slow charge is recommended by all EV manufacturers.
And overheating is the symptom, not the problem here!
I had a friend who bought a Polestar. He didn’t like my take on his Swedish/Chinese noodle burger
For off grid solar, Lead acid batteries are much better than Lithium ion. Much safer, last longer and can be easily recycled. One of my nephews has a Lead acid setup charged by solar and generator because there is no grid on his property.
I wonder how many solar panels you'd need to charge just 10 Polestars between 10pm and 10:10pm.
How many Watts do you need to charge 10 or 100 EVs in 10 minutes. The grid cant handle that.
Give it up mate . Petrodoller will soon be petrobrics
Question; 🤪So 550 cars charging at 380kW each would exceed the power output of Liddell power station in its heyday, 2.2Gw. Are my numbers correct?
The required infrastructure capable of handling those power levels will never be feasible at a consumer level. While charging, each individual charging point would consume the average power draw of over 300 homes
(based on Polestar's claim of 310-380 kw charging rate and the Energy Information Administration (EIA) estimate of 1.214 kw of average use throughout the day in American households.)
Say you dump 50kwh into this battery in 10min…this is 300kw charge. Three cars like this at a station is a megawatt. It’s a 300 houses subdivision. Never mind this battery will be dead in three months at this charge rate. And people swallow this ridiculous garbage.
Hmm, imagine your local servo with it's own nuclear reactor attached to fuel these incendiary devices masquerading as "green" transportation. Our grid as it stands would go poopy real quick.
If you claim that the battery only last for 1000 charging cycles, the important question is how far you can drive. If the car has a range of 400 km when the battery is new and 320 km after 1000 cycles, you will in average get 360 km for each charge. That means that you will have to drive 360000 km before the battery drops to 80% of its inital capacity. At 360000 km most ICE cars will be close to end of life too. So why is this a problem?
Of course all them electric grid problems will go away when the gov'end launches its electricity distribution app.
Watts are watts I squared R is I squared R. High power means heat, no matter how well you reduce resistance. Outside and inside the battery.
Where are they going to locate these super duper chargers? Right next to major substations?
