It's likely a 100% EV home would want the option to charge as quickly as possible, even if they trickle charge most of the time for the sake of battery life. It's also likely that future EVs won't have this battery limitation, just put in the heavier gauge wires and breakers while you're in there if the house is going to be around for the next century.
