—”In comparison, our decent size fully electrical house is wired for 6kW.”
Are you sure?
When we put an addition to our hundred-year-old house we upgraded to a 200 amp service, at 240v.
That would max out at around 48 kWh.
The building code in the area is for a minimum service of 100 amps at 240v (24kWh).
Durn, I mixed up. You are right.
But nobody ever uses that power.
Average US house uses on average 1.2kW of power. Of course zero or near zero sometimes and a lot more in peaks.
That charger 365kW is going on all the time when somebody charges the EV.
And charging stations have often several chargers. You are talking over MW in steady consumption.
