I saw it and at first I thought that it's weird and than I figured that it's just a clickbait as a pro EV's channel won't do that with actual bad news. I also heard before that real life usage and data shows far lower degradation of the batteries. I've also seen the same in other devices. I tend to keep phones as long as they provide what I need and usually the battery wasn't the problem when I did replaced them and those that did it was usually after a system update that probably caused the problem. The battery of my 8 years Samsung tablet still works great (the problem is that the system is slow but once an app is on it works fine and no decent new tablet has such a gorgeous screen).

My friend with a Model Y , a early one at that , has 110k on it now, and the battery still has 97% capacity. Here's the secret, keep charge between 80-20% and rarely charge to 100 and draw below 20. Battery is holding up amazing so far. They are so happy they are keep this car with FSD and getting a SECOND model Y in a year.

[@orbetobe]

The less the average charge level is, the slower calendaric degradation. The closer you cycle are around 45%, the less cycling degradation.

[@Hafiere]

@@RealityCheck6969 If your daily commute is covered by that 50% charge, the occasional trip using more than that shouldn't really degrade the battery too much. Given the range of EVs now usually exceeding 200 miles, there should be a market for people that only need a round trip of 100 miles daily. According to an article from Axios, the average daily distance traveled in the US is about 42 miles.

It's interesting to note that back in 2004 when the Prius came on the scene in a big way, one of the major pieces of FUD was that you would have to spend a zillion dollars to replace the battery probably just after the warranty expires. Well, that never happened. Now we are hearing the same FUD about EV batteries.

[@Dularr]

Curious. Battery failure was the exact experience a friend had with his prius.

[@thomasruwart1722]

@Dularr - me too. A 2005 Prius with a failing cell after 100K miles and 15 years. Fortunately, for $30 it was possible to replace the bad cell and got another 20K miles. So, yes, they do fail, but they don't cost a lot to fix them. You can buy an entire battery for less than $2K these days. That's not much more than an oil change😁

Recently I was reminded that battery life might be something the company decides to destroy with a quick download. I own a pixel 4a, after four years the battery would still last at least 24 hours. Google decided they wanted me to buy a new phone, so they released an "update" that drained my battery in 3 or 4 hours. They claimed they would give us a "free" replacement battery, only to try and charge almost a hundred dollars. Now i worry some car company might try the same stunt.

Thanks Ben. I have a 6/2020 Tesla Model Y Long Range with a Recurrent score of 92 at 98K miles and almost 5 years. Recurrent says my expected range is 285 miles (313 EPA rated when new). We love this car because of its best feature, it's paid off. We travel often, visiting friends and relatives, at 1/3 what it would cost with gas. We are retired, so buying a new car would be tough. When the time comes to replace it in a couple of years I expect battery technology to have made the price reasonable with faster charging. I'm just one data point, but stories are always good.

[@Fluxkompressor]

7:04 this chart shows how crappy LiIon batteries were 10+ years ago. And what all those "anti" people think is that this hasn't improved

[@KiwiandPixel]

2011 & 2012 replacement rates are also reflective of the Nissan LEAF being one of the first mass market EVs. The LEAF hasn't had active thermal management of its batteries since its release. I think they're including it for 2025, finally? When the Model S came out in 2012, they had active thermal management. All cars without it fare MUCH worse. See the e-Golf for another example of an EV that has significant early degradation. Yes, the battery tech has improved, but OEMs have also gotten wise about how to manage their batteries, so the management is probably just as (if not more) important.

[@retireorbust]

Not all batteries are equal. Tesla packs should be looked at alone.

This is an important study, which reinforces what we all know because there are now many 10 year old and high mileage EVs on the road. EV battery life has moved beyond the fear and anxiety stage.

[@paratrooperz1]

problem with the data is that batteries outside of warrantee are not included in the study and the cars that had early failure as a few flaws like sometimes failures dont meet a reporting criteria so sometimes services go unreported or removed. there is also the fact when the battery is replaced under warrantee it may matter if the battery is rendered bad or recycled there is also the fact that when the battery is replaced it doesnt renew the warrantee and somehow they ignore the fact they are testing a newer battery based on a older battery dynamic padding the results

Yes, definitely a used EV BUT you have to check mileage against warranty. I found 2023 that had 89K in mileage, battery warranty was for 80k.

Regarding batteries, get back to me in 5-10 years when we have reliable numbers on battery life. The vast majority of EV's on the road will be nowhere near the end of their battery warranty yet. It will be interesting to see where we are in a few more years and whether manufacturers have a run on claims on 7-year-old cars, or ten-year-old cars are out there in large numbers. For now, for me it's too early for me to make the change and here in NZ cost saving are unlikely when you consider everything.

[@karimmohsen8290]

@00:16 -- _"This comes to us from 'Nature' which is a scholarly journal..."_ Just to clarify, this comes from _"Nature Energy"_ which is distinct from _"Nature"_ itself.

@ That’s an interesting theory about it hiding capacity, but I’m using an OBD-II Adapter with ScanMyTesla which provides unrestrained telemetry data. I can see the usable capacity of the battery at anytime. Both what the BMS displays in the car UI and what the raw readings are. Thats where I’m getting my data. 64.84kWh capacity in my battery. 2.3kW are reserved from the car’s UI for battery safety or emergencies.

Also note that with time, the value of the car tied so close to battery tech will disconnect, and interesting cars will be able to get cheap replacement batteries that perform way better in a decade or so. So if you love your EV, you won't necessarily have to throw it away as it's often claimed today to get better battery tech. This is already the case with Tesla Roadster, BMW i3 and will only increase with time. Old batteries of course reporposed intelligently. Just to say, if you like how an EV looks, drives and makes you feel, but think you have to wait (forever?) to buy into the latest battery tech, well maybe you don't have to... people that keep waiting also forget how much money they are waisting with paying for gas...

[@taythree5549]

Feels like it boils down to not the fact that "batteries will last longer" it's that "due to being more accurate with testing, Our previous assumptions of how long they will last was off by enough that its noteworthy. The actual lifetime of all the batteries that are currently on the wild and assumed to only last say 10 years will now as they would before last 13, 15 maybe 17 years instead. We didn't change the composition or anything we just changed how we were testing them to be more accurate to the random loads places at random times over random durations real life batteries will be treated in. And turned out that having variable voltage from only driving on the road at 25 miles an hour sometimes with the windows down vs with the heat on full blast for others changes the end result over those initial theoretical 10 years adding extra lifetime to it. And of course thats not including idle time it sits charging or just sitting over night which changes the lifetime expectations too. If a car sits in the garage for most of the week only used 2 times on weekends for weekend shits at the nearest 7/11 that battery will always in similar physical conditions last longer then one used daily to drive 3 cities over and back to go to the bank office. Definitely interesting to see the graphics though and well made video about it. Thank you!

- lol, degradation is how much LESS energy it can hold after a certain number of cycles - etc... Note in terms of C rating. Charging a Tesla (75kWh battery for example) 75kW input charge is 1C (75/75 = 1) it is a relative conversion from Energy capacity (kWh /MJ) to Power output (kW or Horses - Joules per second) to allow a guess - estimate of either Run time, or Charge time (output and input).... Let's say - we are using a 220V AC Charger...- charging at "nominal Amps" - and actual kWh and C rate for the capacity... (NB. Li-FePO4 batteries are at 3.65Volts per cell at full charge and Li-NMC - etc (ternary Lithium Cells) are around 4.25Volts at max charge. There is no magic at work here, physics meets chemistry.) 30Amps = 6.6kW = 0.09C (ie. not putting much stress on the battery - BUT will take ~12-13 hours for a full charge. 300AMPS = 66 kW = 0.88C (approaching "unity" - increasing the thermal stress on the battery and will fully charge the battery in around 1.4 hours... 500Amps = 110 kWh = 1.467C (over unity - indicating the battery is undergoing something like "fast charging" - for a large battery significant cooling cost will be involved (possibly not appearing on any bills you actually see, the unseen cost of a great user experience, stressing the battery significantly more than a very slow charge will.) (An 800V AC charger will have approx 1/4 the Amps at the same Charge Power, and likewise a 400V AC charger will be doing about 1/2 the amps out of the "wall outlet"/grid) Of course thermal performance may differ even between exact models of any particular vehicle - Constant Current / Constant Voltage (CC /CV) charge profiles exist to reduce the thermal shock on batteries - the slowing charge rate as the battery reached "completely full" - maintaining at the Constant Voltage for some time longer than the "C- Rate allows the cells to "top balance" (reset the "fuel gauge") and get the charge collectors to fully saturate for peak performance and trip times.)

If this is true, then why does practically every single Tesla owner I follow on KZbin report that their battery degradation actually falls in line with the expected 10% or so that Tesla advises is normal? Despite you saying they designed these scientists designed these tests to mimic real world conditions, the test results do not seem to correspond to real world results. Most Tesla owners experience the normally expected degradation, not the rosy predictions from this test.

Hi Ben, is there any research into battery life if the vehicle is used with V2G? A 🏴󠁧󠁢󠁳󠁣󠁴󠁿 living in 🇮🇪

[@BenSullinsOfficial]

I haven’t seen any. That’s still a new tech developing here in the US

[@mpmpm]

I want to be able to put a car in a shed and take it out 2 or 3 years later, and then continue to drive. That would be detrimental to the battery, not? Also, I don't want a car you see on 'every streetcorner'. Therefore, I want a classic car. Therefore, an EV is nothing for me, until it is cheap to exchange the petrol engine for an electric engine.

[@kevinwhited984]

Thanks, great video!

[@hectorwinslove6154]

Clickbait aside, I've had my EV for over three years, it's never dropped to zero, rarely below 20%. Only charged to 100% six times and and only DC charged six times (to

[@bobbybishop5662]

I not interested in battery life , I am interested in the reports from LA fire fighters explaining how all the burnt EV's have impcted the clean up and how many people have reported chemical poisoning in areas where high numbers of EV's were destroyed by the fire. The number of EV's in that aera of California was very large.

I drive 25k miles a year in average… and did in my first year of my Model Y.

My 2014 Samsung phone battery still works great. I recently found a new 2015 Amazon Fire I never used and it took a charge and I'm writing this comment on it.

[@wadeepperson6906]

Just a few days ago I saw some Tesla packs going for 2200-2500 used not bad really.

[@1507421]

EV's fit only a very limited niche market. Most people who want an EV AND can afford an EV have already bought one. future new sales will decline in the USA and there is no market for used EV's.

[@dylanwhite6539]

6:47 teslas extended service agreement does NOT cover the battery. It is an extension of the BASIC B2B warranty

[@Martinko_Pcik]

What is not considered that battery replacements are triggered even by running over the objects on the road and fender benders despite the fact no damage is obvious. Not so much engine replacements. Complexity of EVs makes then more fragile to damage. But percentage of cars involved in accident like that is perhaps low

[@davidwarriner1639]

Hey Ben. Great video. Regarding the Tesla extended warranty (in Canada maybe also US). The Tesla extended warranty can’t be applied to a used car but it can be transferred. Also the warranty doesn’t apply to the high voltage battery or the drive unit. PS. Please stop with the click bait you’re too good for that.

[@glike2]

This is great news BUT HEAVY REGEN AT NEAR FULL CHARGE IS A POTENTIAL PROBLEM.

[@jounisaari9471]

Most cars don't use regen to nearly full battery. If you charge car full on top of mountain, you will be burning brakes on the way down.

Well, my Doble is still doing just fine.

Ben, you clickbaited me successfully. Even watched your ad segment.

[@ub59]

All great news. Next on the EV mandate agenda should be mandatory recycling of batteries and all car components. It may be possible to get very close to a closed loop in materials with deep recycling of especially mined metals, meaning mining activity needn't be on a steep growth curve permanently with all the attendant environmental impacts. Lithium, iron, steel, aluminum etc. are infinitely recyclable.

[@nycameleon]

Where is the logic in buying an used EV from 2016, expecting a battery replacement, and today putting in a battery with 2016 tech to match the car. Old EV's should have new Battery options!!!

[@RonBme]

My opinion about people having to replace their batteries normally is under Tesla and my understanding would be is because of the age of the vehicle and probably mileage All the other all the other EVs are new and this is one of the reasons that would keep me from purchasing a used TV because the used EVS are and older in age from built day as well as high miles and normally those are the people that are replacing their batteries. Also, about the whole battery degradation, I did read those charts. It looks more like heat and from what I was told it's heat. It's the main cause of battery degradation. I'm driving all day. The battery is kind of warm or hot, especially if it's warm or hot outside. Don't just automatically start charging your battery to fill it up. Allow the battery to cool off and then charred it. Also, it look more like DC fast charging. Could also be a contributor that rapid charge could also induce battery degradation

[@waynerussell6401]

Tesla has least replacements according to ReCurrent and they have the best battery temperature management system.

[@csilver9625]

Wait… Does a 2011 Nissan leaf actually support vehicle to grid? I don’t think so

[@lsh3rd]

It does, actually… it was a feature built into CHAdeMO.

[@csilver9625]

@ that’s crazy! Maybe I should get me a Nissan leaf

[@kkaalaas]

maybe a different title.........you are tryinh to grab looks but it doesnt match the video

[@mjsabie8517]

Taking a battery to zero and back to 100 isn’t the only definition of a cycle. Going from 60-80 5 times would also be a cycle. Is more basically using 100% of the battery’s energy even over multiple charge/discharge cycles.

[@waynerussell6401]

Not quite. The chemistry is not so happy with having the battery at very low or high states of charge, especially if left there over time. In battery testing a cycle is considered from flat to full. Dr Dahn, Tesla's battery consultant, recommends keeping the battery cool and not leaving it at high or low states of charge.

[@mjsabie8517]

@ it’s true that the battery does not “like” being full or empty but long periods; however, that is a different issue from battery cycles. A cycle on the battery is using 100% of its capacity and recharging. Whether that is in 1 use or over several.
