"Location, Location: It Matters Where Your Used EV Comes From" - Article

[Tooney]

In a lot of ways, owning an electric car is just like owning a gas powered one. But, when it comes to buying and selling pre-owned EVs, there may be new things to pay attention to. For instance, other than the possibility of past flood damage, car shoppers don’t tend to care much about where a gas powered car was operated.

However, the location history of a used electric car may matter more than you think. This is because prolonged exposure to heat can accelerate natural battery degradation. And while there are steps that any car owner can take to protect an EV battery from excess damage, not everyone knows how to or is able to do so.

Thanks for this. I live in the 'very dry hot' Phoenix AZ USA area and am glad to finally come across an article that touches on keeping EVs garaged during the day to aid/prolong battery health. (Some of my neighbors have air conditioning in their garages, BTW.) But there still weren't any results quantifying the benefit - probably because accumulating data is challenging. IMO the most important takeaway for desert dwellers who park outside is to keep the EV charged around 50% for the daily commute.

I cringe at the idea of parking my 2022 RWD outside nearly every day without shade here in Phoenix when it's hot. Glad I don't have to.

It is very interesting that there are two superimposed bell curves. There's that little bump in both the hot and cold climates. There's something that's causing a specific group of vehicle batteries to degrade faster regardless of climate. I wonder if that's the charge to 100% vs. charge to 85% groups. It shouldn't be a mileage difference that should be a smooth curve. It could be AC vs DC, but the mix from 100% AC to 100% DC should also be fairly smooth. The charge to X% groups of owners is one of the few groups I can see with a discontinuity like that. I suppose garage vs on street parking is another binary.
