    For the first time I've seen the battery heater kick on.

    Here some pics and info I learned in case people were curious.

    When I first started the charge, I noticed it was drawing 8 Amps & 120v, display says it was doing battery heating. After about ~15-20mins it switched to normal charging and now drawing 12 amps.

    Seems to match up with the ~1000 watt model at (page 76).

    Cool!

    So it inhibits charging completly before battery is brought to the certain minimum temperature?

    BTW: are those images from FLIR One? Users at EEVBlog are reporting that when you save a picture and then open it in Flir Tools you can get a reading below 32F, although accuracy is unknown.

    That's the same battery heater that Tesla used in the Model S, and Rav4.

    Yep seems that way.

    Yep FLIR One, I just checked in the Flir tool, it says that photo has a temperature range of -23F to 12.3F.. yeah I say it's very inaccurate. Temp was likely 28F at the time.
