I wonder if there are any EVs that combine the battery cooling system with the heater! There is still some waste heat in an EV though I don’t know if it’s being well utilized yet.

Tesla already does that, all heat and cooling are in one system. Even the first Model 3 had a system for that.

They do this with the Octovalve and a highly efficient (Tesla designed) heat-pump.

In buses, the problem is so severe that there are some EV buses shipping with fossil fuel heat for cold climates.

And those climates scoff at those of us in Texas and Arizona for needing air conditioning to survive.
