You would not charge directly from the grid. Typically you would use flywheel energy storage in the charging station to store energy. Flywheels are relatively common in managing grid fluctuations in minutes to hour timespan. Use hour to spin up, then discharge in five minutes is 83 kW to 1 MW. https://en.wikipedia.org/wiki/Flywheel_storage_power_system https://en.wikipedia.org/wiki/Flywheel_storage_power_system

Doesn't change the overall power usage though. It is a lot.

  power != energy It changes overall power usage. That's the point. Energy usage does not change, but car energy usage is smaller fraction of total energy usage in the electric grid and manageable.
