Battery cooling experiment

[TickTock]

Remember that the battery has a top as well as a bottom. I noticed it was perceptibly warmer inside the car than out, so the interior is trying to shed heat as well. I have started leaving two of the windows down (one on each side). Looks like it helps, but no repeatable measurements yet. But, easy to do.

Great Tip

I try to leave the windows open while my 2011 LEAF is parked in the garage. The traction battery cools at about 0.5F/hr overnight, but I cannot distinguish a difference in cooling rate with or without the windows open. However, I notice that it is a bit warmer in the LEAF if the windows are closed.

Did you leave the fuse access cover open? It gets quite toasty in there and with windows open you might get some convection currents around the battery with the top of the battery exposed.
