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.

Just wanted to add IF DCFC from a home battery to an EV ever becomes a thing, the capacity of the home battery does not need to be the same or greater than the EV battery.

For example if you have a 60kWh battery EV you could still DCFC it from a home 10, 15, or 20kWh storage battery to quickly regain some miles.
