Three ideas:
1. Swappable battery pack kind of like blue rhino propane. Chips in packs can store charge and state of the battery (old vs. new) to determine exchange value.
2. In the future maybe EV car manufacturers can build battery swap ports into their vehicles.
3. Bolt on car top (might be unstable due to raising the center of gravity) or back/front bumper range extenders/generators to not consume internal space plus aerodynamic and load balanced.
I have to stop about every 65-75 miles anyway just to leak. Front and rear swap ports of 12 kWh each would be perfect.
