Even if you turn cabin heat off and shiver in the cold, the EV still needs to heat its own battery to prevent the electrolyte solution inside from freezing.
The battery should be insulated and use a tiny amount of power to keep from freezing. Like how a water heater uses 50 watts to stay +70 F.
There's nothing inherent to even li-ion that requires much energy in winter to keep warm, it's just manufacturers squeezing efficiency like blood out of rock to get better official stats at standard temperature and pressure.
Same with retractable door handles. Oh they can claim 312 range instead of 310 whoop-de-shit.
But then you have the opposite problem in the summer, where you created an oven for the battery to cook to death under the sun. Worse case scenario, you trigger a fire with the trapped heat.
About the only good conditions for EVs to drive in are climate-controlled labs set at 68 degrees Fahrenheit.
To be frank, I don't think EVs are good tech, and they sure as hell aren't The Future™. But they're a solution in search of a government-made problem, and by God the government is going to solve it.
If it's insulated it's protected from ambient cold and heat, so no death under the sun.
They have to be able to dump ~25 kW of energy when fast charging anyway so they need bigass fans on the radiator.
The reason they don't insulate them is so they get a little less air over the radiator when driving and get slightly more aerodynamic like with the stupid door handles.
