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.
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.
