Some do.
My batteries were 300 AH, 48 volt.
At 60% dod that is 180 ah - and taking efficiency into account, that
is 200 AH.
Just rough calculating, that is 100 Ah from a 115 volt line, and at a
C/10 charge (30 amps) it is a 15 amp draw, and 7 hours at that current
- but the charge tapers, so you are looking at a minimum 10 hour
(tapering) charge cycle. At least that's what I found with mine.

Discharge below 60% and the charging requirement goes up. Bigger
batteries - ditto.

Electric cars don't drag down the grid near as bad as you think.

The socket is 120 or 220. Think 120 - can't be above 30 amps.
Turn on a range top or oven on an electric stove and you exceed
what the car draws.


300M people don't leave their electric stoves on 14hrs a day.
