Each car is typically driven 35 miles daily in the USA. Against a capacity of ~250 miles, this represents many days of non-charging, and thus a lot of flexibility in when charging occurs.
EVs can potentially strengthen the grid: if they are charged smartly, to balance demand.
We need manufacturers, regulators, grid operators to align on how to figure this out.
At the least, grid conditions/pricing should be sent to the car for smart charging.
Mandating 240volt connections in all garages and a large portion of apartment parking lots would also enable the solar excesses of the day to be quickly utilized.
