As I have stated before, Tesla had this idea but gave up on it.
With a Tesla they would have had to undo about 24 bolts, and have a dolly that could lower and raise about 540KG (for 60KW), very accurately or the contacts are bent.
There is also the issue of how old the swapped battery packs are. Would you swap a say one year old battery for one 8 years old?
