Not if you did it right. A good ME could design a method to dock, align, secure, unload, and reverse. 3 min max. *I* could do that, and I am a lousy ME ;-)
If every car used the same style of battery, that would work great. Provided it was designed for fast swapping in the first place. A modular battery rack with a number of battery cells that the car calls for.
Let’s say your Tesla uses a 75 kw battery group, but your neighbor’s electric F-150 calls for 150 kw. It can be the same cells, just arranged in greater quantity on a larger rack.
You pull in to the changing station, get out of the car and go inside to use the rest room and buy some snacks, pay the man, the swapping forklift machine pulls out the depleted battery and re-inserts a freshly-charged rack of batteries.
The upside would be that batteries near their end of life would be located at the station and would become their responsibility to recycle/trash/whatever, taking that burden off the car’s owner. Of course, that would have to be included in the price of the replacement batteries so that it could be covered by the users.
Or, we can just take our vehicles that we have now and fill them up at the local Shell station.
