How bad is battery degradation for used EVs? I examine how lithium ion batteries work, why they lose capacity, and what battery lifetime is like for a Tesla Model S, Nissan Leaf, and Chevy Bolt. Will electric vehicle batteries only last a few years or a lifetime?

FACTS are Tesla 4680 Nk & Si cells can store 5x the Energy & 6x the Power of a 2170 LION. the Silicon can Sequester more LI ions than and other current materiel , as it has more Perfectly formed Bins for which to store Li as it gets used. when you Discharge a 4680 cell , the Reverse happens and the Li ions get trapped in the Bins of the Nickel . furthermore , the tabless design lends itself to Superior Charge & Discharge cycles and you are able to More Completely charge a 4680 cell and More Completely discharge it without loosing battery life. the 4680 cell can also be better thermally managed as it can be Plate cooled , as opposed to side Cooled in a 2170. the Negatives of 4680 is the Possible formation of Li plating of the Annode, which can lead of Degradation. but, careful planning on Charging & Discharge cycles will help mitigate this.

@markplott4820 3 года назад

there are Diffrent kinds of Charging cycles, slow 120v AC, 240v Home charging and DC FAST Charging. there is little or NO Degreation happening when you charge from HOME on a 120/240v AC even if you Charge/Discharge close to the MIN/MAX , this is because batteries offer Resistance in Charging , Resistance creates heat, which Degrades the batteries . so, even IF you own a BEV , you can SAFELY charge to 100% daily in the overnight hours. (usually 7 - 8 H ) on a Full Charge. and this Down time also gives time for the car to Normalize the battery after charging. with the TESLA app you can Chose your PRE Heat time , so when you are Ready to leave , the Battery can be warmed up for Superior Performance. this way you Always leave with an Optimal charge status. the Problem , arises with Frequent DC FAST charging and its recomended to charge no less than 20% state of charge and 80% state of charge , as the battery REALLY heats up , this is WHY most ALL Legacy car makers DONT use 250/350 kwh DC FAST charging , because the CHEAP batteries they use will Degrade FASTER. IF they used SUPERIOR cell technology , like a 2170 or 4680 , they would be able to handle frequent charging at 350 kwh. TESLA is overall the Fastest at 80% in just 10 minutes (1000 mph) , but it takes 20 more minutes to go from 80% to max of 90%. charging is slowed to Prevent overheating & Degeration. Other DC FAST charging is alot Slower than Tesla overall .

Nissan Leaf/ Renault Zoe is the most unreliable EV, it has no active liquid cooling like Tesla, GM, BMW, or some early e-Golf. Hyundai/KIA EV are also good and cooled well. Prius 1st Gen is even better than any Nissan EV. Most Tesla after 10 years are still above 90% capacity compared to when it is new, and even better in Toyota hybrid, more than 95% after millions of cycles/10 years. All-new Toyota have 15 years unlimited miles battery warranty in UK/Ireland. Well, UK has very mild weather, almost never reach above 35C in summer.

Anecdotally, I can confirm your assessment of the Leaf battery. My 2016 Leaf (sold it in favour of a Tesla) suffered horrible battery degradation (< 50% capacity after just a few years. No. Nissan did not allow the battery to be replaced under warranty.). The car became nearly useless except for very short city driving and required overnight charging most of the time. I guess that's what happens when a manufacturer completely ignores battery management issues.

@mylesgray3470 2 года назад

A friend of mine in Seattle is driving an older one to work still. In a moderate climate that doesn’t get too hot, the battery lasts longer but since it has no cooling, a hot climate will kill it in short order. This is like having an air cooled engine. It’s just poor engineering.

Tesla batteries are that good. The reason the leafs batteries do so poorly is because they have no thermal management. Tesla has the best thermal management and the best longevity.

@TSK24692 3 года назад

Good catch! Though I would clarify that if you compare it to Eric Way's numbers, then yes it does seem like it will drop like the Leaf, but he drove 100K miles in 3 years. Based on the data points provided by the other sources, it does trend kinda closer to Tesla...although it's kinda hard to make that call because it's still only been three years and trying to trend out to 10 years based on 3 years data really does amplify any variances which may or may not be incidental. In any event, that was a REALLY good catch.

@Jackpkmn 2 года назад

Something i thought was very interesting is that my new laptop has an option to prevent the battery charge from going over 80% and when you use this option it also pegs the cpu to its lowest clock speed and the gpu capacity to 0 while the battery is below 30% to prevent you from dropping it much below that. Pretty smart.

@LordSandwichII 2 года назад

Something you didn't mention here is that batteries packs are not just one giant indivisible unit. A battery pack is made of individual cells which can degrade unevenly over time. Some battery packs are also divided into batteries (ie. groups of cells) that the charge controller can isolate if the battery doesn't match the rest of the pack well enough for it to operate safely. This can be cause by a dead cell in one of the batteries. All this means that if your battery loses a lot of capacity, it is often possible to find and replace bad cells in the battery pack, which can vastly increase your car's range, as it brings some of the battery back to life. Indeed there are already services out there that can do this for you, and it's a lot cheaper than just replacing the entire pack.

Theoretically. But with right to repair being in such a sad state most of these companies will either force you to replace the whole pack or do it through them at an astronomical price. I think people will be in for a rude awakening when they lose the ease of repairability they've taken for granted with gas.

Really!? Did you actually look at the graphs presented? Please use the graph at 21:20 to tell me when the battery is expected to reach 20% capacity. According to the graph, never! The rate of degradation slows down the older the battery becomes!? This makes no sense. Not a single car in the entire database has a capacity of less than 75% regardless of mileage and use? Not a single battery died? The chart is so flawed that its paradoxical.

Smart Easy DIY, But he completely failed to define exactly what he means when he says “charge/discharge cycle”. If a vehicle has a range of 100 miles and you’re cycling between 100% and 25% does mean you’re driving 75 miles per cycle? And what about cycling between 75% and 65%? Does that mean you get to drive only 10 miles per cycle? Because if that’s what he means by, “cycle” then cycling between 75% and 65% doesn’t look very good any more. In fact, it then looks worse than cycling between 100% and 25%.

It would also be interesting to hear your thoughts about energy density and the resulting weight of battery packs in the current fleet of electric vehicles. My understanding is that the Bolt for example has a battery pack that claims 50% of the vehicle weight. And it is not uncommon to see battery packs that weigh 1,000 lb. I struggle to see how this makes sense in a passenger car and even less so in a pickup truck.

This is a very nice video with clear explanations. One small comment is that LEAF do have active thermal management which heats up the battery if too cold and prevent excessive usage when too hot, what they do miss is liquid cooling, which becomes a relevant issue when living in hot areas

Nice overview! One more thing to add is that for long term storage of your EV (say, a few days or weeks), it is also good to keep your battery SoC (state of charge) low at about 35-50% and before use, again to charge it up to 75% and cycle it at low DoD's. It will last much longer. And definitley look out for EV's with some form of active cooling. But whether an EV is good for you is based on your commuting lifestyle.

Second this. Don't know how well it translates to cars, but Apple recommends charging your iPhone to 50% if you plan on storing it.

I talked to a Tesla engineer a few month ago and he told me that they were amazed by the current degradation of their batteries. Apparently it is significantly less than expected. He told me that Tesla is planning to put in place a battery shop for out-of-warranty cars in 2021 and that Tesla will buy back the old battery to reuse them (EDIT : After a recycling process of course !!!) in Powerwalls thus reducing the price of the new battery significantly.

@chargeeverywhere 4 года назад

That would be an awesome program if they do that. The Model S’s are starting to come off warranty, so having a method to offset the battery price would incentivize people to hold onto older cars.

@MrGoogle87 3 года назад

He is only talking about averages, they sold me a brand new model 3 with -13% missing capacity and tell me “all good no errors, battery capacity is secret and health also, bye sir” Model 3 SR+ with 208/240 miles.... They just first ghost me and talk about driving slower, charge habits... (tried All)

I'm also REALLY glad that I resisted the initial temptation of buying a used Nissan Leaf so I wouldn't have to spend as much on a used EV. The range limitation of the Leaf pretty much killed that option, frankly.

@MrKockabilly 2 года назад

This is a very informative video and does make me have a second look in this aspect of EVs. Just my minor qualm is the use of bar graphs that starts from 50% (or 70%) to 100% instead of the full 0 to 100% range in 21:20 15:03 22:45. This has the effect of making the values "look" worse than they really are and actually a subtle "tactic" esp by government officials in presenting things that they like to exaggerate in the visuals. Sure the graphs are still accurate and discerning viewers should take note of that, but this partially defeats the core purpose of using graphs which is to quickly AND accurately visualize proportions in a glance.

I have an 8 year old Nissan 100 thousand miles on the clock and 11 bars of capacity (81 %), driving in UK climate. Battery never goes under 20% charge and majority of time charged to 80%. Still going strong, and can get 70 miles on full charge. Bought for £7000 4 years ago. Very happy so cheap to run it has almost paid for itself. For a second hand car from £4-8000 they are well worth the money IMO.

@chargeeverywhere 3 года назад

@NateDecker1982 3 года назад

And as a counterexample, I have a 2012 Leaf and the battery is at 50% capacity. In the winter, I can't drive with the heater and have to stop to charge on the way home. My commute is only 20 miles each way.

@chargeeverywhere 3 года назад

Wow! Do you charge at work? I’m guessing not or that’d be downright unusable.

@shanajackson5044 3 года назад

@@NateDecker1982 That sounds bad, do you drive in a temperate climate? Also do you drive in eco? When i first got the car it had 12 bars (87 %) and I used to drive only in normal mode, then after 6 months I lost a bar and decided to drive in eco. I have lost only 4 % capacity in 3 and half years since I did that, so that in addition to never letting the battery go below 20% and living in a temperate climate has most likely made the battery hold up so well. Also not sure if it makes much difference but my car is white, so in theory it could contribute to keeping the battery temperature down on hot summer days (since the leaf has no thermal management for the battery).

@1davidsmall 3 года назад

@listerdave1240 2 года назад

An often overlooked but very important failure mode of lithium ion batteries is delamination. For a battery to work properly the layers must be in very good contact with each other. This makes a big difference between cylindrical cells and pouch or prismatic cells. With prismatic or pouch cells there is no practical way to maintain pressure on the layers to keep them in contact. You could in theory use very thick steel plates to keep the layers compressed but they would have to weigh even more than the actual battery to be effective. Cylindrical cells on the other hand can very easily maintain that pressure simply because of geometry. Very often when prismatic and even more so pouch cells fail it is by neither of the mechanisms described in the video but simply by the layers losing contact with each other. In cellphone batteries this is easily seen by the puffing up of the cell, caused by gas building up between the layers and forcing them apart. In a cylindrical cell this does not happen as the cell is not allowed to expand radially due to the metal cylindrical case. Instead of pushing the layers apart the gas slowly works its way to the outer edges of the cell and out through the relief vent. This all makes me wonder how little EV manufacturers care about the life time of their batteries beyond warranty, Tesla being the only exception I know of that do seem to care. Pouch and prismatic cells have some significant advantages in terms of weight and even more so cost but only at the expense of being much less durable.

It would be nice to see those charts adjusted for total miles driven before degradation instead of charging cycles. Personally that is a more useful metric for me.

@briandbeaudin9166 2 года назад

There is no way to determine what you want. For example, if you live in a cold climate much of your battery capacity will be dedicated to keeping the vehicle warm. Load weight, type of driving and terrain will also have substantial impact on mileage. Also, testing is done related to charging cycles because mileage can be so variable depending on the above factors. Finally, to add icing on this cake, as the battery degrades, more charging cycles will be required to achieve the 'original' capacity, in effect accelerating the degradation!

@tech29X 2 года назад

Excellent video and explanation. I wish you elaborated a little more on the impact of cold weather on an older battery. I heard a lot of horror stories where people got stranded on the highway, when temperatures dropped suddenly late at night while they were driving home from a long day trip. It's not like you can have AAA come and loan you a battery pack till you get to the next charging station. The industry needs to move towards some standardized "power nodes" to facilitate a short trip, 20-30 miles, to get you to a charging station without getting the whole vehicle towed.

I own a 1st gen 2013 Nissan Leaf, I am it's second owner, purchased it with very low mileage a few years ago, the tested battery degradation is just below 10% which is fantastic for a car purchased new in the latter half of 2012. I have charged it to 100% a few times to be able to make some ~80 mile round trips, I paid a few thousand $$$'s for it & in the last year have only needed to replace the very well worn original tires which has made it an excellent purchase.

@@perseverance8 Your situation is called an 'outlier' in regard to a statistical sample's single point of data (aka: your situation is the exception, rather than the norm/rule). CERTAIN electric vehicles (BTW, a MUCH better label/description of these type of vehicles is a 'battery-operated vehicle') definitely have their place in our society. These vehicles include mopeds, golf carts, forklifts, segways, & children's toys. Unless battery technology takes a HUGE leap forward from what we have now, there is ABSOLUTELY no way, IMHO, that transportation (especially in regard to cargo transportation/trucking/shipping) will NEVER become a fossil fuel-free system. Just because California's idiot Governor states that by 2035? (I think he set a 2035 deadline, not 100% sure), all new vehicles manufactured after 2034 in the state of California must not be a fossil fuel-consuming type of vehicle. I'm definitely missing some pieces of information in re: to this idiotic mandate CA has set for itself & it's poor citizens. I'm not at all fond of the way B.O.C.s cannot be 're-fueled/re-charged' to 100% (aka: a full tank) in NO WHERE near the amount of time it takes to fill a fossil-fueled car. AND, for those of us that sometimes 'get a wild hair' & just get up on a Saturday morning & just start driving to 'wherever the road leads'... well, that's not gonna happen in an E.V. (B.O.P.). Why not? Well, unless you know where every charging station is located within a 200 mile radius, good luck going on a 'random adventure' without the constant worry of being stranded w/out any battery power left in the car. And NOPE, someone can't just bring you a few gallons of battery-power in a can. : ( *BOTTOM LINE: BATTERY-OPERATED CARS SHOULD CONTINUE TO BE, IMHO, AN ★OPTION★ FOR THOSE (FEW) OF US THAT HAVE A DRIVING SITUATION THAT FITS THE WAY A B.O.C.
