Perpetual motion machines don't work. That's why serious EVs don't have a fan on the front to recharge the battery while driving.

Solar panels dont work either, or they would be covered in solar panels.

It might be something they will do at some tme, but for supplimentary stuff, lights, heating.

If the EV has air conditioning, that heat has to go somewhere. While EV traction motors are normally water cooled. 1st gen Nissan Leaf has an 80KW motor. Assuming that it is 95% efficient, that is still 4KW of heat that also needs to go somewhere. And more advanced EVs have active cooling systems on their batteries.

Either way, radiators are definitely still needed on EVs.
