Tesla publishes encouraging battery degradation data

20 June 2024
Tesla's data suggests its Model 3 and Model Y batteries retain an average of 85% capacity after {{200,000 miles}}, potentially outlasting the average lifespan of a vehicle.

How many cycles ie (city or highway driving) highway being worse for evs. And the temp of the battery day by day i.e. Las Vegas desert or up in Canada.

This information doesn't help much. Most cars make 10-15 000 km per year, so most cars will never reach the distance from the article. Typical ICE car last 15-20 years. I want to know how good battery will be after 15 years!

Meanwhile I’m over here at 56k miles and already down to 88%. Hopefully it will start doing that slow down everyone talks about It’s been a linear slide to where I am so far. (In case anyone asks, I charge my YLR to 75% at home)

2020 m3P after 3 years (85.000km) SOH 89%, after 4 years (112.000km) SOH 87%... not bad for EV with 500hp ;)

To be honest the results are not surprising at all. They are consistent with the expected degradation to 80% after 1000-3000 full load cycles depending on the battery type. The battery will outlast the car. That's for sure.
What I would find A LOT more interesting is actual car range data after so many Km. I wonder if there are other reasons limiting the car's range over time (e.g. reduced motor efficiency). Does a car with 85% of the initial battery capacity also have 85% of its initial range?

Your analysis is misleading. Even in the 32% of cases the variance is not so bad. At worst, from the graph it appears to be 20% loss.

These numbers really make you wonder about the actual range of electric cars. If the battery lasts as long as the car itself, that's a total game changer! Less stress about battery life and more focus on being eco friendly.
