when I read the article this was what stood out to me, as well. Last winter it got _really_ cold where I live. Does that mean that if I got a Tesla with an LFP battery it would be drastically less useful in the winter? Seems problematic.
The battery can be heated, so you can reduce the cold weather range problems by preconditioning the battery before a drive. Naturally this uses some power, so Tesla recommends keeping the car plugged in when it's cold so it can keep everything nice and warm.
No different than using a block heater or diesel coolant heater then. ICE vehicles use a lot more fuel in winter too, and take a long time to get up to temperature.
Indeed. Telsa's will keep batteries at reasonable temperatures when plugged in, but not optimal. There is a departure setting available so you can make sure your battery is full and at the ideal temperature for any scheduled departures.
