I saw your post regarding plugging in the Lightning in cold weather. I am a snowbird and will leave my truck in an unheated garage for 4+ months. Ford's Owner's manual says to charge the truck to 50% and then disconnect the 12V battery for long term storage. Do you have any idea if I disconnect the 12V battery but leave the truck plugged in, will it still draw a few kWs to warm the HV battery? Any other advice on this? Ford's online support just basically repeated what the Owner's Manual said. Thanks. JimWhat I see on my Lightning using a JuiceBox EVSE is that overnight it will briefly draw a few kW for a minute or two every few hours from the wall, presumably to warm the battery pack a little.
I don’t know what happens if you’re unplugged but it’s either that it’ll use its own battery to do the same or it won’t try to warm the battery pack as much / at all.
