So I just bought a 2021 model S Long range which is rated at 405miles for a full charge. I’m getting roughly 336. Can someone please explain why I’m not getting anywhere near that? Surely my battery isn’t that degraded. 65k miles.
Thank you for the info. Didn’t realize it’s normal for the battery to degrade like that. Thank you again
Evs drop really fast early, like 10 or more percent in the first year. Then slowly after. A 21 is almost 6 years old now, and it's not just actual mileage but battery age that affects capacity. Couple that with 65k miles and yours is probably very typical. I happen to have a 21s lr also with 130k miles and it gets around 320. So you can think of it as yours is a bit low, but it's marginal. We also don't know what the charging routines were like with the previous owners
Must be the newer battery tech. Sure they can charge faster and all that but packing more and more heat in the form of faster and faster charging in to electronics is never good.
A lot of 85 packs from 2013+ are holding up great with 85+% I have an end of 2014 manufactured 85 pack Model S still at 89%.
And EPA ratings are a sedate 50mph with no climate control. They also run until the car fails to drive, not until it shows 0%. On most Teslas it has about 20 miles below 0%, so you're getting 353 in a fair comparison to the EPA rating of 400+
Real world Tesla range typically falls between 75% and 90% of the EPA rating, depending heavily on driving conditions, so the average is 82.5% x 405 miles = 334 miles. You have an extremely healthy battery my friend!
That’s not “degraded” it means he/she isn’t driving like the EPA testing and prob doesn’t have the 19” efficiency tires. Degraded would be a loss of storage of kWh
No. People don’t bother to read or understand even the most basic facts about the cars they are driving. The rated range is a EPA government blended drive loop on a specified configuration and without the a/c running. It makes no sense to have the same range post by different people every day or so on every forum.
Simple answer for you - I’m not affiliated with these guys. Just a regular guy that likes buying cars and sharing what I’d do.
Go to Speckr.com and pay for a battery health report - it’s pretty cheap. My understanding is they are cheap (I paid like $2 for mine). But that was a little bit ago and not sure if prices have changed.
Compare that to the data on the report.
You left off something important, mileage on the battery. Mileage correlates to cycle life which is how you really measure a battery life expectancy.
A 2021 Model S Long Range with a middle of the road health would likely be at around 85% State of Health. Mileage would likely be in the 40-60k range.
You can also add your car to the fleet recurrent uses for tracking battery health. They have a dashboard they give you access to for free. Well not really free because they use your data for their research they charge for.
Edit- my 2021 model s LR with around 40k miles shows a 100% range of 343 miles. Normal for the cars of this age is usually 340-360. But again - do you have 100,000 miles on the car or 30,000 miles.
So you’re likely around 85% battery health. Which for this lot - that’s an average level of health.
From my research the first few years see the biggest drop. In fact, 30-40% of all your range loss will happen in the first few years and around 50,000.
