Just starting the car doesn't warm the battery, no. So you don't want to warm the inside if it's 37 degrees?
Anything it does while not plugged in would have to use battery power. That's the opposite of improving range. The whole point of preconditioning to improve range is to use grid power so that you don't have to sacrifice battery power to bring things up to temp.
Not necessarily “conditioned” but the battery would be warmed up by whatever amount of heat is produced by the charging process. I have no idea what that is for L2 charging. Preconditioning, obviously, uses the heating system to bring the batteries up to a certain temperature. I suspect that temp is greater that that which you would achieve by charging an additional 10kW.
The heat from charging is almost nil, so charging alone will not precondition the battery if you just bump up the charge target.
Thanks! I was not sure about that and could not recall reading anything. I knew it could not be much or I would have seen it as a conditioning strategy.
I do try to set departure time if I know a time. It is just a hassle. Then I have to remember to turn it off. Guess took 3 years for drunk button to work. Maybe 3 years more they could add pre condition button.
In addition to all the other comments here, let me just add that when you turn the vehicle "on", be sure to press the brake (that is, put it in the On mode rather than the Accessory mode). While you can do most of the same things in either mode (except drive, obviously), Accessory mode doesn't charge the 12V battery.
