150 deg F and lightning: any benefit of plugging in? Sorry if this has been discussed before but I can't find it and can't possibly be the only one pondering about this one Background: 1. I have my car scheduled to start charging every 1 AM. 2. Since the owner's manual says that the car should be plugged in, charging or not, I leave the car plugged in, or plug it in as soon as I come home after driving. 3. Now in the summer we have tremendous thunderstorms almost every afternoon here in Orlando. Appliances go out left and right and my neighbor's house just burnt down. Needless to say I am a bit uncomfortable leaving the car plugged in during these storms, so I unplug when I hear the first bolt of lightning. When it is over I plug it in again. Question: is there any benefit to those few hours plugged in while not charging? Or shall I just wait until nighttime? (Some people have suggested that the full thermal conditioning of the battery needs shore power but I can't find anything definite). PS. This time of the year it is 150 degrees in my garage, so parking with "energy saving" or somehow otherwise restricted battery thermal management doesn't feel like an appealing option.
