Moral #1: You can't ever charge an EV fast enough, and even if you could, you can't dissipate the heat of charging in the battery safely.

Moral #2: Pump and carry chemical energy, and convert to electricity on the fly. This is why hybrids eat all-electric vehicles' lunches, and always will.
The reactive chemicals in a battery can be quickly changed and the energy density of metal-air batteries is quite high. Recharging such a battery entails dumping the oxide and replacing the metal cathode.

Reducing the oxides is best done close to the power source in bulk. However, it can be easily enough decentralized but not likly to home units.
