Lower temperatures increase conductivity, but slow down chemical reactions in batteries and cause humans to thaw out their frost-bitten toes with excess heater use. Not good for electrics! These, in addition to range, are all problems to be solved - but like most folks, I’m not buying until they are solved.
EV manufacturers have moved from basic electric stip heating to freon-based thermal heat pumps to generate cabin (and battery) heating.
Heat pumps use less electricity to create the same amount of heat than electric resistance heating strips. A heat pump is basically an air condidtioner run in reverse.
EVs that use an on-board battery array as the energy storage medium are a dead-end, and only made sense for niche applications, like in a warmer year-round climate, and with the availability of cheap electricity, confined to short commute distances.
The smug emissions for these vehicles is off the charts, and greatly outweighs the other “advantages”.
If only there were a way to generate electric power on-board the vehicle while in operation...

They already have a solution called hybrids
