So do gasoline powered vehicles. EVs do not make power, they store it from another source, usually fossil fuels.
Correct. However in the event of a evacuation it is easy and quick to refuel a car vs a electric car. A gas station can probably brign in a 25-50kw diesel generator and be fully operational to pump gas at dozens of pumps.
The average fast charger needs 60 kw per Google, so probably you would need at least 80kw per charger. You are looking at a minimum of 500kw genset for just 6 chargers.
The former gets delivered via a F250/350 the latter needs a semi.
