This question is asked out of ignorance - I simply don't know how Tesla manages battery temps.
I've read in a lot of threads about how much of a range hit we'll get in bitterly cold weather (and, yes, I consider 10F/-12C to be bitterly cold). I've read a lot about how high temperature is bad for battery lifetime (living in Phoenix, this is more my concern). My question is - how hard does Tesla try to keep the battery in a reasonable temperature range?
1. Does the car try to warm the battery in bitterly cold weather using the heater when it's parked? This would seem to be a bad idea when unplugged, but might be a REALLY GOOD IDEA when plugged in.
2. Can I heat the battery through the phone app before I go outside? Seems like a few kilowatts expended through the resistive heater might liberate more than that from the warmed battery pack.
3. Does the car try to warm the battery when driving by using heat from the motor? I believe that both the motor and the battery pack are liquid cooled, so it should be possible to get free battery heating by simply running the coolant in a loop through both.
4. Does the car try to cool the battery in hot weather? When June/July rolls around and every day is above 110F/45C and the worst ones above 120F/50C, will the car try to actively cool the battery when it's parked? How about parked and plugged in? I can protect the car at home, but not so much at work.
Thanks for any info you've got.
