Good idea this. The main complaint about totally electric cars is the charge time and this would negate this for a small cost. The company taking the battery could charge it up and use it as stock for the next hot-swap to come in.
If they can get this right (both the infrastructure and the price for the service), it could really help electric car adoption in the future since you'll be able to "re-fuel" just like a normal car, in some respects.
