Leaf batteries can be quite a bit more degraded than this video suggests. My 2012 has 8 bars, which means it's lost 34-40% of its original capacity. If you search for cheap used Leafs (Leaves?) you'll find plenty of examples with even further degraded batteries. People tend to keep these around as cheap city cars, which is why they don't contribute to the overall percentage of batteries "needing replacement," but that doesn't mean they're still in good condition.

My Leaf is just over 8 years old and still has 80% battery SOH. So my leaf at 2 years older than Kate's reference point has less degradation than in her report and your car at 5 years older has more degradation. You're not comparing apples with apples here.

Chemical Reactions: Cold temperatures slow down the chemical reactions happening within the battery. This reduces the battery's ability to deliver power efficiently. Internal Resistance: Cold weather increases the internal resistance of the battery. When resistance is higher, it becomes harder for the battery to release energy, which affects its overall performance.

Great discussion again Kate.

This was at Warwick and Leicester universities where infant EV battery/traction systems groups were meeting. They warranted the battery then to get the technology accepted (my supposition, no proof ).

Not mentioned in the video are the two different types of lithium EV battery chemistries, NMC and LFP, with NMC garnering a vast majority of failures/replacements. LFP now makes up around 30% share of global EV battery deployments, and while it has lower charge/discharge rates, it lasts far longer cycles, has much better thermal stability, no nasty cobalt and none of the manufacturing/design flaws in LG/SK's NMC cells. CATL at the outset made a huge bet on LFP prismatic cells and it appears they are a global winner as a result. A large % of Tesla's now feature LFP batteries.

Not saying it is without its faults (bad seats, crappy touch screen, slowish charging, etc) but it’s been good value for money overall. Add in the savings in fuel, oil, spark plugs, coolant, other fluids, belts, hoses, filters, etc and it’s been an economic blessing too. Not to mention time saved not going to the gas station and mechanic. If it holds its value in the aftermarket that seems justified provided the battery pack gets replaced.

From my own experience and from watching these videos from Bjorn, the problems with the older packs seem to be mostly relating to moisture getting into the packs and this could be avoided with maintenance. They have also had the same issue on an eGolf, which was spotted during an inspection. And I've also noticed that the failures of early Tesla motors are causes either by seals allowing flood water into the motor and ingress from the motor coolant, both issues can be avoided with preventative maintenance. It should be possible to keep a lot of Evs on the roads for much longer than we have been used to with ICE cars, we just need to understand the specific issues that can crop up for each model.

In U.S. there is no legal requirement for OEMs to provide minimum battery pack warranties on BEVs. California (CARB) and EPA do require minimum battery pack warrantees for PHEVs, as the battery pack in PHEVs is considered part of the "emissions system". So packs in a PHEV have minimum warranty period of 10 years, or 100,000 miles just like a catalytic converter. For BEVs a number of OEMs selling in US market have competitively adopted ~8 year coverage with 75-100,000 miles. Some OEMs even vary pack coverage based on BEV model. Since there is no legislation to enforce, this could change in future depending of competition and agreements between automotive OEMs (eg: as a way to lower EV MSRP at a future date).

[4:58] I have a 2015 24kwh Nissan Leaf. It's done over 91,000 miles in the seven plus years I've had it and the battery State Of Health is 80.4%. I've always used my Leaf experimentally as well as practically so no-one can argue with my mythbusting facts because I've lived the proof of them. The idea that Leafs automatically have terrible degradation is wrong. In fact, in the early years, when I changed the way I charged my Leaf it went from 79% SOH back up to 93% SOH. That figure changes all the time depending on how I discharge and charge the battery. And I don't preserve my battery particularly well compared to many other users. Of course I'm in the UK and this may be different in harsher climates. But nevertheless, my battery degradation was not significantly worse than any of the more modern cars you feature in your graphs. So just to summarise, after seven plus years and 91,000 miles my battery is still above 80% State Of Health. Please note and stop reporting Leafs as necessarily poor for degradation. By the way my charging history is 1,519 L1/L2 charges and 1,144 Rapid charges. That equates to 43% of the charging being Rapid charging. Not even Rapid charging eight times in a row on the way from London to Edinburgh caused me to have charging issues or failures as was being claimed at the time. And I repeated the exercise the next day on the way back. I could reel off tales of mythbusting experiences in my Leaf all day.

Hyundai/KIA havent improved their times on warranty repairs though, I have had to wait from mid-August to get approval for an OBC replacement; and, as the last time I checked, shipping times from Korea were 10-16 WEEKS, I might not get my car back until 8 months after the OBC died. My loaner is a new Sportage - I can only wish they had given me the newer Soul

GM didn't honor the warranty at 60,000 for me on my gas car... so there is that from the old school car makers.

LOL Zoidberg! Yes. My 2015 Leaf is now at 79% state-of-health. And I bought it used in 2018 and it was already quite mishandled at that time (85% SOH). And battery-preserving charging to only 80% SoC went out the windows this winter due to range issues.

I think I would worry about it if I had a Hyundai EV6, with its $60K replacement cost. Yes I know, that's in Canadian dollars, but I am in Canada.

Quoting more than the car is new for the battery replacement is some bull-shit though. The REAL problem is that all these traction batteries are proprietary: with no third-party replacement parts. So the manufactures can charge whatever price they want for a battery replacement. There are some exceptions. A firm in New Zealand has reverse-engineered the Nissan Leaf batteries. They are working on a replacement with water cooling; but are more focused on their local market.

Just curious if you're following up where the battery packs being replaced end up. Recycled? That'd be good. Landfill? Not so good.

Hi Geoff, Most faulty battery packs are resused,, not recycled or ending up in landfill. They are reused in virtual power plants. Often for network balancing, where they are far more effective than the gas power station alternatives, or as storage. It is estimated that a 15 year old vehicle battery pack has another 15 years of useful life in situ.

The bottom line is there are just too many batteries in the EV packs linked together up to 7000 in some cases I believe , even one battery that fails will bring up a dash warning. If the single bank was split up into 6 x seperate removable banks for example with much larger batteries say 10-20 batteries per bank and the ability to easily remove a bank for servicing a faulty battery and or replacement of that bank it would reduce the failure rate and cost to a manageable level also the cost of manufacture would be greatly reduced.

If you could avoid the cell balance problems. As I understand it, when they refurbished a used battery, they replace bad calls with cells of similar degraded levels to the undamaged cell in the remainder of the battery pack. A rebuilt battery is not returned to original performance levels. It is repaired to function at a level equal to that particular battery just before it failed.

Please tell me more about the benefits of L2 over L1 charging (other than speed). I don’t drive a lot of miles in a typical week. It’s usually not a problem that it takes 3 days to fully charge my Bolt at L2. For those rare occasions, it’s not hard for me to hit a public L2 or DCFC. I’m not sure how long I’ll stay in this house. I’m reluctant to spend the money to install a L2 charger. What am I missing?

The other big one is charging efficiency. Higher voltage charging is simply more efficient in terms of “power delivered to the charger circuit that gets stored in the battery,” plus any “vampire drains” become a smaller percentage. If you use remote start/cabin-preheating functions, then using a L1, all of the power is likely going to heating the cabin; whereas on L2, you’d still have enough extra “juice” to add energy to the pack. I even had one instance where I had to turn down the L1 charging amperage to avoid blowing a circuit breaker when charging in very cold environment, and the vehicle had to use energy to heat the battery to charge it at all - I was getting only the barest trickle of actual charging. Less than one mile added per hour of charging, since most of the power was going to heating things up so it COULD charge. Where a normal L1 would have produced about 5 miles of range added per hour.

Level 1 is the granny plug, that should take days as your looking at about 2kW to fill a 50 kWh battery. Level 2 is a 7 kW home charger (or 11 to 22 kW if you have 3 phase power) which should recharge overnight. Level 3 is a DC rapid charger, where you hopefully should get 10%-80% in 20-45 minutes depending on the car and charger.

Most defects on the batteries of early Tesla Model S were caused by moisture - not cell failure. NOT fast charging them frequently and NOT pushing the car hard sometime will never warm up the battery and let the moisture dissipate. Tesla made multiple changes on the Model S/X packs over time to reduce that risk. But it’s still a good idea to fast charge and push the car regularly. Source: EV Clinic, Zagreb, Croatia

Quick thought about reduced range in winter, no doubt it's only a minor contributor but no one mentions that in higher latitudes much shorter days will mean more use of head and tail lights in winter than in the long days of summer.

@usa-ev

Nice thought, but lighting has little to do with it. For example my EV has the lights always on day or night summer or winter and the range still drops in winter. Also, range drops even during daytime driving in winter. And doesn't drop during night-time driving in summer. And finally, the amount of power for lighting can be determined and when compared to battery size it's negligible.

@ps.2

7 ай бұрын

As @usa-ev says, lighting doesn't amount to a lot of power usage, really, especially with LEDs, and also modern vehicles may light their headlights (at a lower setting) in daytime as well. Much more significant is the heating. The one downside of the insane efficiency of electric motors compared to combustion engines: you don't have a ton of waste heat to get rid of, that you can tap into for free to heat the cabin. So you have to explicitly generate the cabin heat, either directly or via a heat pump (more expensive and complex, but much more efficient). Along with heating the battery itself, especially before rapid charging. I suspect even that's not the main factor for degraded range in winter - that would be either the lower capacity of lithium ion cells at cold temperatures, or the increased rolling resistance of snow and slush.

BUT, as I said, the auxillary equipment is NOT powered DIRECTLY from the high voltage battery. If you use your car (ICE or EV) regularly the 12-volt battery gets topped up and can hold it's charge for weeks or even months. You will NOT be drawing from the high voltage in order to put your lights on and your range will NOT be affected. The power drawn into your 12-volt is already there for use and won't be drained to the point where your HV battery needs to rescue it unless there is something wrong with the 12V anyway.

Love my Ariya. My Leaf didn't seem to adjust for temperature and I almost got stranded because real life range was about 40% reduced on a winter day. My Ariya drops it's range estimate very accurately I found. The other morning it was 32 degrees F and the range went from 205 miles to 150 miles. And I drove it down to 13 miles range and it was bang on. But if you don't know this going in, you might get a nasty surprise. Now that I know this I plan accordingly. And take the ICE van if I don't have enough range plus a healthy cushion.

I've got a 2014 Tesla Model S, now 10 years old, on the original battery and still going fine for now. I might keep it forever just to see how long it lasts. Range loss was higher in the first few years but now the loss from year to year is negligible. Over the years I've mostly charged to 80% - 90%. A fair amount of fast charging as well from a period of years where I was traveling for work.

Great video as always. Love the Acorn!! 🤣

Brilliant presentation, very interesting information (obviously well researched), & extremely informative. Instantly subbed. And 'as solid as a Vogon constructer fleet' was the cherry on top! Well done Catherine, & anyone else involved in the production of this video. 👍 Also, greetings from Australia.

I recently got a 2013 Chevy Volt with 63,000 miles on it. The battery has no issues. The battery is rated for at least 160,000 electric-only miles (which being a plug-in hybrid it doesn’t actually have to do all the time). GM bragged about the battery tech and the chemistry being developed in partnership with LG Chem and GM making the packs themselves and using Lithium Prismatic cells.

I finally got to see the rest of this one! Ironically I've been busy delivering EVs, that according to our media, no one is buying?! Its been mostly Merc EQCs recently and yesterday it was a Funky Cat. Maxus have been doing a one year deal on their electric pick up for £81 + VAT a month (it was at £51 +VAT, but those deals are gone). I just wanted to chip in with my own EV battery experience, as I have a 2016 Model S 85D that Elon pays to fill up (free supercharging). Last summer, I got a message on the dash saying the HV battery fuse needs replacing, but I'm okay to keep driving. I booked the car in with Tesla Bristol and on the day, I waited supping on the free coffee. After an hour the technician came out and said he was not happy with the seals on my battery pack and they would have to remove the HV pack. They loaned me a Model 3 to go home in and the next morning the technician rang to say they were going to replace the pack and keep the loaner until its done. They called again later to say they weren't happy with some of the HV electrics and were replacing those as well. The car was 7 ½ years old with 250,000 miles on the clock and they changed the HV battery and some of the electrics under warranty. I'd not had any problems and the range was 220-240 miles. All I paid for was for the fuse replacement and I'd asked them to check a handbrake fault, which they found a broken wire and only charged 1 hour labour and a new connector. In 5 years on EV driving (4 Zoes, 1 Kangoo ZE, a Horwin CR6, and the 85D) this is the only time I've spent money on the brakes. Since collecting the Model S, I spent just over 6 weeks in southern Italy, covering 5,500 miles mostly on free supercharging and I will be heading back again shortly. (Houses are a tenth the cost of property in the UK). I should close by saying, I could never have afforded the current car, without having saved money in the previous years running EVs instead of ICE cars/vans/motorbikes. And having a luxury car, albeit with high mileage, is also made possible due to the low cost of ownership. Driving down to Italy is also much cheaper then it used to be. I spent €70 charging during my last trip, occasionally using the 22kW AC outlet in the town square. Thank you as always, for the interesting content.

If I heard you correctly, battery replacement is at 1.5%. That's not good, because that means ar least 1 out of every 100 cars will require a replacement. Fuel vehicles have a considerably better engine success ratio of about 1 vehicle in every couple thousand needing engine replacement.

Good coverage of one of the biggest anti-ev mobs talking points. A good guague to work with 1% of all batteries. When there are problems out of warranty, it’s inderstandable that people would be scared of the consequences. Ian Sampson (KZreadr from UK) has recently had one of his family ENV200s (leaf based) start showing a problem. 1st suspect is a faulty module. He’s now weighing his options as it may not be economical to repair/replace the pack vs him scrapping it / selling on and returning to a cheaper diesel option.

The figure rate for the EVS is similar to The Lemon rate for gasoline cars. The reason a lot are happening is because there's a lot of Eevee's on the road now. The actual rate is quite low. For example the electric car fire rate is 25 per 100,000 but the gasoline car fire rate is something like 67 per 100,000. And the hybrid vehicle rate is over 100 per 100,000.

What I've noticed recently, and it was very briefly mentioned in this video, are stories of vehicles needing a battery replacement for $60,000.00 US. I know such stories are usually produced by anti EV people/groups but there is usually a small kernel of truth to most stories. Are you aware of anything about these vehicles or stories? Naturally when one needs to replace a battery pack when it is out of warranty it will be expensive but it's no different than replacing the engine on an ICE vehicle. It's going to cost a lot of money. For example I used to own a 1984 Toyota SR5 4X4 pickup with the 22R engine. The engine wore out so I got a price for a replacement engine from my local Toyota dealership. This was in 1986 and the quote was for $12,000.00 CAD. I had the engine rebuilt for $3500.00 and even that was expensive. I don't remember what a used SR5 would have cost in 1986 but $12,000.00 was probably more than my old truck was worth at the time.

@@-V-K- The only reason the battery needs replacing with such minor damage is that Hyundai techs don't do any electrical repair: so they want to replace the whole thing as a unit, instead on taking the modules out, inspecting them, and putting them in a new case that is not dented. And even IF we assume that the battery is not repairable: there is no reason the component should cost more than the car is new. They only quoted the rediculous price because they think their EV customers are stupid enough to buy another car from them after such treatment.

Ive been driving EV's since 2009. The problem is people are still thinking gasoline. Something you can dump in anytime you desire and just keep going. The range usually remains the same virtually throughout the life of the gasoline vehicle and they usually dump the vehicle before that for another one. The EV on the other hand must have some serious thought before purchasing or building because the motor will usually out last the vehicle but not the battery and as the battery ages the range diminishes and you can't just willy nilly just go plug in and fill up in a couple minutes and off for another 400 miles and for sure not for the life of the vehicle. The range diminishes and if you calculated your needs wrong you might find yourself on the short end and needing a tow because your range is not what it once was. Then you will eventually get to the point where you won't be able to go the distance you once did and even though the vehicle is still in great condition and still has loads of oomph you just can't go the distance. This is where the person begins to feel the battery has failed but in reality it has not. It has loads of life left but just not what you calculated. The best EV to date is my Fiat 500e but it is in reality just a local around town car with an occasional short jaunt on the freeway. Not meant to travel outside the realm of maybe 35 miles because after you have it for 10 years the capacity will be just a bit around 50 miles. You still need to get home and not every one has access to public charging stations and with that most won't use them because the cost is higher than they would consider so they don't and only charge at home like me. So it is more a failed long term planning vs a failed battery. If the battery fails you will know it. The capacity will drop considerably and quickly and or the battery will erupt in a ball of flame consuming everything. Plan accordingly and don't plan on what the dealers provide as a standard range. Plan on your range being that which the car will give you in the middle of winter with the heater cranking and traveling at minimum 65 mph. Do that for a real world drive and you plan around that. If you don't you may find you don't like them so much. I like them because they are more efficient than gasoline. Not because it is going to save the world from some arbitrary thing.

There was the recent story about a man who bought a Tesla model 3 to use it as his UBER vehicle & had to replace the battery after 120,000 miles - all in *_12 MONTHS_* !!! He did the equivalent of 8 years worth of expected driving in 12 months!!! Sure, this is a fringe case, but it debunks your debunk!

I can not forget about that uber driver from California that bought a second hand Model 3 and supercharged twice a day. He had a completely ruined battery within a year. Beside that he also bought it just before the price drop and now has big negative numbers. Just outside of the warranty. He let Tesla "refurbish" the battery for 9000 USD. Most likely they just replaced some bad cells. After a short while he had the same problems likely from other previously almost bad cells that now decided to die. This is a huge problem and the way you charge should not affect the life span of the car that much. His range now dropped to like 30 miles.

I like the battery lease option that companies like Nio have. I haven't looked at the economics, but it is interesting to have the option of fast battery swapping and of purchasing a car without a battery which can then be leased on a monthly basis or purchased at a later date. It would be great if a certain percentage of EVs could make use of a standardized battery pack. Standardization should help to reduce costs and provide more options for battery servicing and purchase of replacement. I see Evs as being in their infancy and it will take several years for the vehicles, infrastructure, and service network to mature.

A battery could replace the entire vehicle structure, and the composition could involve a solar cell outer skin laminated directly to the vehicle shaped battery. This would reduce alot of cost and weight of a vehicle, and batteries could be as segmental as the lego block in multiplatform adapatability. This would reduce alot of landfill and even moreso if the material blend isnt such as concern of small cells having too little of things such as chemical separators that are being mentioned as a common failure point within battery design. The thing is though, with automation able to produce these things, people will no longer be needed nor need to build planned obsolescence into their product line for job security reasons at their core.

it's not only total failure that concerns buyers. Reduced range due to degradation is a major issue and not as easy to deal with a as aweak laptop or phone battery. Charging a car is a hassle in comaprison.
