    AFAIK all but the first generation of EVs in the US have cooling/heating systems for their batteries so they can preserve it's longevity. That being said, it does mean shorter ranges because some of the power from that battery goes into the cooling system.

    “The worst case really is a car that sits in an unconditioned garage in Phoenix all summer without being plugged in,” says Scott Case, co-founder and chief executive officer of Recurrent, a startup that generates battery health reports for EV customers and dealers. “That will cook the battery really quickly.” If the car is plugged in, it can use charging power to keep its battery cool.

    I'm not aware of any EV that requires it to be plugged into power to use the cooling system. As long as the battery is in a good state and you don't abandon it for a while, like Case says, you should be OK.

    This feels like a scare article, but I know that not everyone knows about these kinds of thing. Every car owner should actually take the time to read the owner's manual thoroughly to make sure they know how to properly maintain it.

      I work in R&D for EV trucks. The bit about keeping it plugged in isn’t so that the cooling/heating system will function, it’s to keep it from draining the batteries. In extreme weather the cooling system can drain the traction batteries in just a few days. We are constantly monitoring the charge level in our test vehicles when they sit unused for a while so the systems don’t get depleted.

      Yes, I do think it's a scare article, but hopefully in a good way? Every year our local newspaper has articles about safety while hiking, not taking selfies near cliff edges etc. Basic knowledge,...
