Some QC locations (like Supercharging parking lots) have issues with enough power for all vehicles to charge at full rate at the same time. Some QC locations suffer high power demand charges for those times when many cars are charging at full rate at the same time. On idea for a solution would be to make QC locations as parking lots for car share cars to be dropped off. You leave them sitting in the spot, plugged in, and the car will sit until it gets rented later. The benefit is that with V2G technology, you could make that car be a battery buffer for other "just passing through vehicles" to charge from instead of from the grid. Then the charging station can "trickle charge" the car share vehicle back to full when the lot is being less used. This could solve multiple problems, including where to leave car share cars when not in use. Having dedicated spots just for that is wasteful since those cars are sitting doing nothing until they get rented. Having shared "buffering" / "charging" stalls seems like it could help with some of these concerns. Getting coordinated V2G working would need to get done first though. Another benefit is the car share cars could be swapped on a road trip. You drop off your almost empty, and just hop in a full one and carry on your trip.
