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.
The notion that the electric car can't draw above 30 amps is based in
flawed assumptions. While they can be charged from a 15 amp wall
outlet, that's a very slow charge that will take a day or more to bring
a fully discharged electric to capacity--it's intended as a convenience
feature, not the normal means of charging. The standard charge is 220v
using a dedicated circuit and special connector that can deliver up to
80 amps. Some models also have a DC fast charger that typically works
at several hundred volts and several hundred amps. The fast charger
generally requires a separate hookup from the utility company.
Many fork lift truck chargers run off 3 phase power.550 or 600 volt
primary.
