But the filling stations will not have the capacity.
Do you have any concept what power flow requirement are needed to fill up multiple batteries at the rate necessary to equal the driving range and fill time of a typical gas powered car?
15 gallons of gas is equivalent to about half (.495) a MWH. That means to fill an equivalent battery in 15 minutes youd need to pump in energy at a rate of 2 MW per car. For a small 8 pump filling station thats a capacity of 16 MW. Wed need that much electrical transmission capacity, or more, going to every filling station in the country.
The countrys entire electrical distribution system would need to be replaced from the ground up and replaced with one capable of orders of magnitude more power generation and transmission. Replaced. It is flat out not possible to upgrade the current system to meet that need.
Not going to happen.
