Stop messing about, 125 A three phase or about 90 kW. Sort of power
required to charge an electric vehicle in the time it takes to fill a
fuel tank. Slight snag is domestic supplies are, at best, 100 A
single phase, a mere 23 (ish) kW.

Most supply cables to houses are shared with lots of other houses and
sized for an average loading. If lot of those house occupiers buy an
electric vehicle, they will likely all want to charge them overnight.

I know I would, because we have E7.

The average load will be increased several fold. Loading on the
sub-station will be increased severalfold.

Would it do the electric cars any harm if all the ones on a street
were plugged in all night but some kind of "smart" distribution system
switched various charging points on & off at different times?
