This is all good news and all, but we need to keep from setting the bar too damn low. I do not consider 100,000 miles to be a huge benchmark. I understand the constraints of a study of EV batteries since most EVs simply haven't been around long enough to study, but we as consumers should not be accepting EVs to be throw-away items like gadget-makers have turned most consumer electronics.

Yeah 90% charge remaining is still a decent number, but your 200 mile range when new turned into only 180 mile max range in less than a decade. And since you typically are told to only charge to 80%, your real world range is only 144 miles or so. In the winter that will be down to less than 100 miles.

People shouldn't be falling for misinformation about batteries (like the repeated dismissed myth that they are worse for the environment), but there is also a lot of overly positive info out there that doesn't reflect reality.

So, and I’m sure I’m not alone in this, my EV (a Polestar 2) charged to 80% gets a theoretical 220’ish miles range (I’m basing this not on the EPA range, but the calculated range in the car based on my driving habits). Now I say theoretical because I’ve never tested it all the way with my largest trip since I’ve owned it being about 70 miles one way. My average “long” driving days are only 50 miles round trip, and an average day where we take the car out is only about 12 miles total in the day. I’ve had a single time where I haven’t charged in my garage at night (on a 110v nonetheless!) and that was the 70 mile road trip where I parked in a garage with a charger so figured I might as well.

Now I bring all this up because I know I’m not alone in this. Sure my driving doesn’t represent everyone but it’s also not singularly unique. Even if this car loses 10% of its range it’s not going to affect my use of it. I know everyone thinks that everyone else does daily long commutes and huge yearly road trips, but that is only a subset of the population (maybe it’s you! I don’t know). But this constant discounting of EVs because they don’t meet some bar for certain groups is disingenuous. They already meet the bar for vast groups of people, and if your daily usage is super high odds are there’s an EV out there that can meet it, even after a drop to 90% years down the road.

This is the first positive press piece about EV batteries that I’ve ever seen.

I've read a few about the longevity of Tesla's; especially those used as taxis and work vehicles. Done over 300,000km in a few years, and still doing great.
