So I purchased a used 2012 leaf a couple weeks ago. I've been parking it in my driveway and plugging it in over night and setting the timer to start charging in the early morning. It is common for it to have zero bars of battery temperature and after driving awhile gaining one or two bars. The other night we had a server snow storm so I moved it into my unheated and uninsulated garage for the night and left it unplugged and about 60% charged. Now it is not charging at all. When I plug it in there are no beeps and no blue lights. It does display that it is plugged in on the dash. The timers are turned off. Has the battery frozen? If so how do I go about thawing it? I drove it to work this morning and the turtle came on. Leafspy says soc is 39.9%.
