The only thing I have to work on is the battery heating for winter. The battery heaters only activate while charging. I have done some tinkering with bypassing the heater relays for force the heaters to run.
As far as balancing, I'm not too worried. A quick charge or two should not take it too off balanced. It will be balanced next time I nominally charge.
I was thinking you could possibly plug in the regular EVSE cable and set it to value charge at some odd time. I think that would cause the car to cool the battery if needed...but you are right, you will probably quick charge and be on the road promptly so no harm in any event.
And yes, I agree about the balancing. particularly if you charge it only to say 80% which I think is typical of fast chargers, some imbalance not a factor.
Very clever....I like the idea!
