Heat pumps have largely solved the battery capacity problems with cold batteries (though not the fast charging rate). I don't have numbers for Rivian, but heater-equipped EVs from other manufacturers now routinely post numbers in frigid temperatures that are under 20% range degradation. You're basically just paying for the extra energy to run the heater.

From what I’ve seen only a few models have a heat pump if you were to buy today so buyer beware. It might be technically solved but it’s still an issue if you want to buy an EV in the next few years.
