Tesla ultra high mileage battery degradation - real data, lots of cars

- This is the second video on Tesla battery degradation and taking a look at the mega or hyper mileage cars with result up to 250k miles. These are fleet results and the higher the mileage the fewer data points we have, so caution is required, but the results may still be of interest.
If you've watched the first video, some of the results will be similar, however we also reflect on the battery warranty and the impact of age as well as mileage has on the battery
0:00 Intro
0:20 85 Battery
2:00 90 Battery
2:40 100 Battery

Please compare NMC and LFP batteries
Hi, please, where we can find de data you are using in this video. I try to find in tour web Page but can't i find It 😢. Thank you.
Are these data posted on the website somewhere? Couldn't find them.
Drive it like it's a Toyota Camry, limit fast charging to only when absolutely necessary, limiting most of charging to low level 2, high level 1, and get your ~1,000,000 miles out of your battery and motors. Avoid charging to 100%, unless, absolutely necessary. For day to day driving, limit state of charge, to between 70 and 80%. Leave the car plugged in as much as possible, to allow the battery management system to maintain voltage balance on the cells. Voltage balancing becomes more important as the battery ages, because differences in self-discharge rates from cell to cell become greater.
Thank you for providing the way to charge. New to the EV world and trying to get up too speed as our M3 RWD is due in the next 2 weeks. We have wall ants plug-in chargers ready but like to learn about the battery life and longevity.
@@alastairhatt360 If you don’t mind a 1h long lesson by a professor, I can recommend this video.
He goes over the most important factors for battery longevity.

I think you may have been drinking the Musk-aid Vincent.
These 'million mile' Tesla's all invariably have had 10+ motor and 3-4 battery replacements.
Your advice in general IS solid, but too many elements out of your control, particularly with the drive train
@@alastairhatt360You have an LFP battery in that car. You should charge to 100%. But your Tesla car will tell you that. Also, fast charging an LFP doesn't appear to be as hard on it as the NCM. Just follow what the car tells you. Helpful to actually read the manual (is under service tab and it's in your app.) LFP was referred to as the million mile battery, but Tesla refused to ever use that term themselves. And to get your tires to last a long as any ICE car tire, drive in "chill" mode. I mean, unless you want to experience the acceleration when you first get it, but driving in "chill" mode and my tires last longer than manufacturer states. Oh, I'm driving about 80,000 miles a year in the model 3std rng RWD.
Waiting another couple of years before I even look at a EV. My ICE car has no hassle like that. 😂😂
Thanks for this. Good info.
Thanks. We've part 3 coming next week, this looks in detail at the performance between the different factories.
@@Tesla-Info That will be cool also :)
It would be useful to know how many vehicles are represented in each data set. I’m guessing that there are individual vehicles which provide multiple data points.
Very interesting. The rate of AC charging would have been nice to know.
I think it's fair to assume that most high mileage cars have a high rate of suc charging.
Sadly we can't access the split of AC and DC charging through the APi ptherwise we'd have looked at that.
I know the numbers must be miniscule, but I would love to see what data you have on the Model 3 Mid-Range batteries. Mine is a 2019 with about 232 miles. I believe they were rated for 264 miles when new, so I'm around 87% capacity after 75k miles and five years. But that 232 miles is the same as when I bought it 3 years ago used, so it doesn't seem to have degraded over my 3 years and 40k miles. I'd be curious to see more on those 62kWh battery packs.
The problem is that if you're using the official range numbers, they tended to be overinflated from the beginning. So, it might not have been that much more than 240 or 245 to begin with. 5-6% battery degradation over the first year or two and then it leveling off to stay pretty steady after that is pretty in line with the data you see here. Doesn't seem to be out of line.
Could anyone speculate on EV towing , would that likely degrade the battery in a similar way that the Performance Model 3 seems to degrade VS the Long Range Model 3?
If it's really heavy and you have to overcome it with higher power that heats up the battery, perhaps you'll see some impact over time. Perhaps. I don't think there's a linear relationship between towing and degradation - or at least there will be too many factors to predict how it will affect ANY ONE car's experience. I imagine you'll see pretty much the same type of curve here, where it levels off and doesn't degrade much more.
Why does it seem that you guys are gate keeping this data set please make avsile to the public immediately
My 2023 str rng has 65,000 miles in 9 months.
Damn. Putting in miles. That's 240 miles (4-5 hours?) PER DAY for 9 months. That's... wild...
Some of those batteries totally suck. I’d be pissed if my battery was down to 70%
You can see how Tesla, with all this info (and much more!) are able to carefully tailor their warranty, generally to the detriment of the owner
Just remember that the vertical axis here represents kWh, not percentage.
@@logitech4873 yeh some of them are very low
@@mattx4253 Usually those will be warranty cases.
@@mattx4253 Yea. But you're seeing mass data. The same way some transmissions poop out way before they're supposed to (had to replace mine twice in my Subaru). The same way some engines need replacement way before they're supposed to. Manufacturing is not perfect and there will always be outliers. But you can see from the data that outliers are... OUTLIERS. They don't represent the general experience - and when they do (ie: battery gate) you see where that problem happened clearly and that it doesn't happen to the other cars.
As for the warranty.. don't worry lol. California makes Tesla warranty their battery for 10 years and 100,000 miles minimum. If you have 70% battery degradation at any point before then, you can get it fully repaired or replaced. And honestly, judging from these numbers, if you hit 70% even after really high mileage, you're in the minority.
This is very informative and useful information, but I do have some issues with it. The fact that we can't differentiate between fast charging vs slower L1 or L2 charging, and also we obviously can't determine how the car is being used or what it is being used for. I suspect that if we could get a clearer image of those statistics, the story might be a lot more clear. What is to say that those with really high degradation aren't cars that are being used for ride-share, frequent towing, frequent spirited driving, or even simply being parked for long periods in improper states of charge for storage.
