Heat = wasted energy, no? Which kinda tanks the efficiency of your EV. Also, cooling the battery pack should not, with proper design, necessitate running the A/C to cool the passenger cabin.

...if you go back to a car that's 120 degrees inside from sitting in the sun, your AC is going to be chugging away for the first 20 minutes or so once you get on the road. That's unnecessary consumption.
Not as much unnecessary consumption as keeping the A/C running for the whole time the car's charging. Of course a roof or other sunshade helps. So does leaving the windows open.
