You sure you don't mean Texas? They are the ones with the inadequate power grid.
Actually, what you just said was completely false
A post on Facebook claims California "literally" told electric vehicle owners to stop charging because of power shortages. That is false.

Total power for air conditioning use far surpasses the amount used for charging cars.
As far as electric vehicle charging, There are plenty of papers that show we have excess capacity in the evening when people charge their cars. There are already smart meters that give you cheaper rates at night and electric cars can be programmed to charge during the cheaper rates.
Of course there will always be the flip phone people that deny the future.
