Yes, that is the only feasible way to do this without enormous expense.I'm not technical enough to explain how this would work but I've always wondered why we couldn't have some sort of residential fast charging solution using batteries?
"Charge" the batteries slowly through solar or grid and then transfer than energy from the battery to an EV using a DCFC. That way you don't have to pull huge amounts of power from the grid.
The optimum solution is to be filling that battery with solar energy during the day while you're away, and dumping it into your car when the sun goes away.
You still get the benefit of driving "for free" without have to actually be consuming it in real time as the sun shines.
