Hi Larry and All,
Or they could just insulate the EV's so little heating power is
needed for heating is one of my choices to lower heating power. The heat you
don't need is the cheapest of all so starting there is a good choice whatever
heating source.
Phase change salts can be recharged by the grid while batteries
are charged plus heating the cabin can work

Some time ago I did some calculations showing that if you used gasoline for
heating an EV for all the heating you do for the cabin and the batteries,
you would only consume 7-8 gallons of fuel per year. But if you only used
it when needed, such as for long trips where you need maximum range for
your EV, you would only consume about one gallon per year, an absolutely
trivial amount.
So I think heating with fuel should be a standard feature for electric cars.
