It’s not a sustained draw all night for every car. I averaged 17kWh/day in the last week. My energy provider schedules the charge in 30 minute chunks. It will charge during the peak time if it wants too ( and I get off-peak charges).
Both the UK and US have this already.

> Through smart charging EVs can in fact help to balance the system, helping consumers use green power when it’s plentiful (and often cheaper) and avoid times when there’s more load on the network. Vehicle-to-grid technology could even send that power back to the grid when needed.
> With this in mind, the UK Government has introduced Electric Vehicle Smart Charge Points Regulations, which ensure that EV charge points will have this smart functionality.
> Similarly in the US, Smart Chargers and Time of Use Rate programmes will support balancing the load throughout the day.
