A group of us were talking the other day during a break in racing our electric LiPo powered RC trucks on the snowbird parks paved oval track. The thought hit us that to make electric road cars viable they need quick change batteries like we us on out RC stuff.
You pull into a station and a robot slides out the universal battery pack and slides in a replacement fully charged one. The one removed goes on the stations charger, and you are charged for the amp hours that were used from the pack removed. RFID could read out stats on the battery when you pull up, then the system spits out your credit card receipt and
VVVVV
Off you go.
Pickups could use multiples of the universal battery packs. "I will take one pack today, thank you!"
A standardized battery pack that could be swapped out makes much more sense - It would be like people do today with propane tanks. Manufacturers would have to agree on a form factor, connection method and maximum discharge rate to make this happen. As posted, larger chassis vehicles could accept multiple packs while a compact would only take one.
Current vehicle charging could remain an option if you have the time to plug in (like when you refill you current propane tank rather than swapping it out).
