Power generation is not the same as deliverability.
Right now there are power problems in the summer when too many people turn on their ACs.
If everyone plugs their cars in the same time, the peak power demand will overload the grid in that area.
Power is not the same as energy. You can have a billion joules go through your power outlet, but not a billion watts for very long.

That's true of everything. If everyone turns on their water at once there will be no pressure. If everyone flushes their toilet at once the sewer will be overwhelmed. Luckily people do not live their lives in synchronicity. Even if they did, most people are going to charge overnight since it will take 8 hours or so to charge their car and that's when prices are cheaper.
No one flushes their toilets for 8 hours together.
Like I said, we already have problems in many areas when the ACs turn on in the summer between 9am-8pm. Not every AC turns on at the same precise time, but during those daylight hours a lot of them are on at the same period of time and we have power problems.
Right now EVs have it easy, there currently exists a fuel infrastructure to take the energy load. Right now we have a dual system, in the future it will be a single system of electricity only, no hedge.

Nobody in those areas is going to be charging their car at that time. Electricity is over 50 cents a kWh during those hours. It's the equivalent of paying about $6.75 a gallon for gas.
