Hoping a trickle-charge in the garage will do the trick.
Good problem to have, right?
I wonder if Tesla (or anyone else) is looking into variants of the "home power station" battery which can be used to rapidly charge an EV. It would be cool if you had a big battery like that you could trickle-charge 24x7, then dump the juice rapidly (perhaps at L3 speeds?) to your car.
It would be expensive, obviously, since you'd need another battery pack at least as large as the one in your car. Still, I can see lots of applications.
