I believe they “just work.” Electric motors don’t stop working at low temps. I think it’s mostly just range that’s impacted since EVs can’t use the inefficient part of an ICE (e.g. energy produced by gas not captured by the powertrain) for heat, so they have to run heat pumps. (Along with battery chemistry not working as well in low temps)

Depending on the EV you you void the battery warranty keeping it in extreme temperatures like 40 below. And it affects the range.
