-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 FWIW....I believe that the "thermal control" on the 2013 batteries is a set of heaters that can be turned on, and does not include any active cooling.
You can see what I think are the heater elements in the upper right of this image: http://www.summet.com/blog/wp-content/uploads/2015/04/bms_busbars_complete1-1024x768.jpg The 2013 battery modules do have more "air holes" in them for passive thermal heating than the 2011/2012 modules. My advice is to set the leaf to only charge to a maximum 80 %, and set the timer such that it starts charging in the middle of the night (3am? 5am?) whenever your outdoor temp is the lowest. (Potentially stopping just before you plan to leave in the morning, if they have a set schedule, so that it doesn't stay at 80% longer than it needs to.)
