I have wondered about battery cells of a standard size and rather than go to a charging station for an hour you go to the battery station and turn in your discharged battery cells and pop in charged cells - maybe pay a rental fee for using the batteries. If things were well designed a battery change-out could be done a lot faster than waiting for a charge.
The way of the future might be hydrogen fuel cells.
The hydrogen runs over the catalyst, platinum, and that releases electrons to the electric motor.
The technology is here, and it works.
Problem is, the hydrogen pumping stations, we need them all over the country, like gas stations.
I think it will happen.
