Would be useful for really cold places, as the battery heater wouldn't use as much power due to insulation. Think Yukon. Places where the battery heater is on nearly all the time, trying hard to keep the pack above 0C.
Worse than useless for me.
True. Most fans don't even know that, but Tesla's pack is far from perfect. In my climate,
it's also "worse than useless". My Leaf has battery below -5*C for two months. Heating it up every day is nonsense.
Nissan's chemistry can regen and DC charge even at -5*C. That is not possible on Tesla's.
Note, Model 3 doesn't have dedicated battery heater and going to SuperCharger after battery has been cold soaked might mean an hour of idling just to get the pack warm enough to take ANY charge. Unheardof and worse than useless.
