Yeah that's a good point. Ours uses the same refrigerant system as the AC to cool the battery, and the actual "charger" for the battery is inside the car being controlled by its software etc. The cables that plug in on the outside are technically just power wires, with the charging brains inside the car. That would be amazing if they could update the software to rejuvenate the battery once a year or something.
it would almost certainly need to be done at a fast charger, not at home unless it could do only a few cells at a time. Remember the golden rule: "Don't set the house on fire by overloading the wiring".
