A little coal stove down by your feet?  Propane might be more

Roll the window down like I do, pussy ;)

When the battery is charging it will generate plenty of heat.
The battery will be warm and ready to go in the morning.

The same self heating of the battery can be used to prewarm
the cabin.  After that, scavenge heat off the motor controler.
As for A/C, use a DC motor to turn the compressor.  That's
how they did it on the EV-1.

& what happens when you park out somewhere?  There is virtually no
heat from a modern motor controller.   Which is why it is modern.
Use a DC motor & lose 20 miles range.
That is the point. There is no surplus or throwaway energy in an
electric car.  The only chance is, as someone remarked, a little
propane heater.

Or insulation, and a thermostatic valve to divert coolant from the
small motor-generator into the battery pack. Hit the remote starter
when you wake up. The motor could also spin an A/C pump.

If I had the funding it would be a pickup truck with an air compressor
and arc welding output included.

What small motor generator is this?
