The reviews from Tesla owners who have their own experience with the car in cold weather is interesting.
Can anyone tell me why the car discharges when plugged into a 120V supply? It's mentioned in one of the links above and in the NYT article.
I'm aware that you can't supply much current with a standard 120V supply, but why would it discharge? I would imagine at a minimum you'd have a very slow charge rate, but from these two anecdotes, it appears in cold weather it still slowly loses charge when plugged into 120V.
Is the car constantly heating the battery? I could see that being the issue as engine block heaters draw a ton of current and they take a long time to heat up an engine block. I'm assuming the battery has a lot more thermal mass than a 300 lb engine block.
