A look at this link might help:
Tesla uses the waste heat from the cars electronics, motor and battery charge discharge to run cabin heat. Ac would be a draw of course. Ev are a philosophical change. We have been buying FF all our life and letting the waste energy generated at the well head, refinery, and distribution end go unnoticed except as price. We only notice EVs limits and costs because we are having to build the infrastructure from scratch in the 21st century where costs are more obvious, labour is expensive and regulation prevents the kind of reckless development that brought the car FF industry about. Having said all that I’m not ready to jump on board the Ev wagon yet. I would be that farmer in his field with his team seeing all the steam tractors appear at his neighbours saying “not yet” until one day the ford n series appears and then aha off to the glue factory no looking back.
