New study of 1,300 EVs busts battery degradation myths

[davehu]

The study found that an impressive 8 out of 10 of the used EVs tested retained over 90% of their original battery capacity....BUT... Unfortunately, they didn’t share the average mileage required to retain this capacity, as they virtually tested all used EVs that came through. Nonetheless, this is a fantastic result that should give used EV buyers a ton of confidence.

Didnt read it, but having owned a Volt I can guarantee there were no Volts that retained 90%! Total bricks after 12 years.

I've known plug-in hybrid owners who said pretty much the same thing. It's probably because their typical usage cycle has been to charge to 100% every night, then commute on the battery until it's flat and switch to the ICE. All the evidence shows that such a cycle kills batteries quickly, while ABCing a full EV doesn't.

Yeah unfortunately the article and the linked article in Swedish didn’t mention the age or mileage of the EVs. So this info seems kinda helpless without that. But in general, it’s age that degrades EV batteries more than miles.

I’ve had several get down to 85%, but they’ve all seemed to level off around there. Either that, or I stopped caring….I’m pretty sure it’s the latter.

At some point in my EV ownership, all of this started becoming noise. I equate it to someone saying a 200,000 mile Honda still makes 90% of its original HP…that’s nice. And that’s actually a really good thing IMO.
