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.
Most electric cars have battery cooling, but the Nissan Leaf doesn’t. It works fine until you try rapid charging more than 2 times in one day.
I suspect that some high performance cars would also have motor and inverter cooling. This would likely not be needed for regular road cars as the motor and inverter don’t produce much heat.
This is true however for op it’s not something you can or need to watch or keep track of. At least for my car if it detects something wrong with the battery cooling/heating system it will tell you. Otherwise you just ignore it.
yes an electric motor has an efficiency of around 90%(thats what my engeneering teacher told us)(google tells me 64%) means that is the percentage of how much energy is converted to work the rest of that is emmited as heat
I’m not a car person, so excuse my lack of knowledge. But do electric cars have/need cooling liquid? Just wondering

Yes, almost all do. Except for the nissan leaf.
