Some have cooling liquid for the battery and electrical components. Some blow cold air over the battery.
And then there’s the Nissan Leaf, which just lets the battery cook, knowing that it probably won’t die before the warranty is up.
Though it’s a bit more complicated than that - sometimes you want to heat the battery or the passenger cabin, and sometimes you want to heat one thing while cooling the other. A good thermal control system can handle moving heat around as well as getting rid of it or taking it from the surrounding air.
