90%+ is good, but I gotta say-

“The evaluation examined how battery health evolves for individual electric car models after they have traveled 10,000 Swedish miles, which translates to 100,000 kilometers or roughly 62,000 regular miles.”

10k Swedish miles? I didn’t know Swedish Miles was a thing! Learn something new every day.

Back to the battery- this is why we need vehicles that over deliver mileage originally. Because everything works against getting rated range- weather, tire inflation, hills, wind, fast charging (maybe less than we think), battery age… So 300 becomes 270. 400 becomes 360… that loss is easier to deal with if you start with a higher number. Combine that with charging speeds at 80% and greater being so slow you’re really typically looking at 240 miles range @ 80% brand new, take 10% off the top and we’re down to 216. I can’t speak for most people but dropping below 20% is nerve wracking, whatever your low comfortable number is that chews even more off the total.


400+ is (for me) the number that I don’t worry about It anymore. More IS better to an extent, as long as it doesn’t get so heavy you need even more. I think this is why pick up trucks that are EVs have a hard time. Weird that the Semi works out so well.

I fully and wholeheartedly agree. When I bought my 2024 Model 3 Long Range AWD, it was rated for 341 miles when new, and that is under ideal conditions. Now with nearly 37,000 miles on the odometer, I'm already down roughly 6% of total battery capacity, which isn't terrible, but still isn't ideal after only owning the car for a little over 2 years. I know degradation isn't linear, but even so, it isn't great knowing that my battery is basically slowly eating itself away as I use the car more and more.

In an ideal world, we would have batteries that could retain their range for much longer without needing ridiculous added weight or range to compensate for degradation. But since for now that isn't the case, then the next best solution is what you said: add basically 100 to 150 miles of range to prolong the degradation a bit more.

Another reason to add more range or at least to change the way that EV range is shown is highway usage. The rated range on most EVs is a mix of highway and city driving, and while that isn't technically wrong, I think it would be better to rate EVs individually on both city and highway. In that way, buyers know exactly what they can expect if they do a road trip or stay mostly in the city.
