Interesting that the Leaf battery BMS/Heater system accomplished a similar goal with similar technology years ago - likely for 1/10 the cost!

OK - maybe not to the same extremes of temperature. And, a major missing link is direct solar DC charging - need that hi voltage MPPT CC that is CHAdeMO compatible.
