Solid state batteries will still require energy to warm the cabin so range will be lower intge winter.

Yes, and ICE cars have to burn fuel to warm the cabin so their range is lower in the winter. There is no world in which running a heater doesn't use energy. The question is how much, and at what point do we stop caring.

 

[Pragmatic]

ICE are only less efficient while the engine is warming up. Once warm, e.g., long trips, fuel economy is unaffected by low temperatures, the cabin heat is heat that would otherwise be wasted through the radiator. Of course winter fuels have less energy so there is that.

Similarly a heat pump in an EV is just drawing heat from the battery pack that would otherwise be wasted. Except when the battery pack is too cold and has to be heated up itself. A solid state battery in theory would run just fine in lower temperatures, mostly eliminating that problem.

Not with that attitude…
