Battery swap stations have been tried here and there, including one big effort in Israel and some current efforts in San Fransisco and China, but I’m personally doubtful that it will ever come to anything for privately owned passenger cars for the reasons outlined in this article:
If standardized battery packs make sense anywhere, it’s probably for long-haul electric big rig trucks. Currently they don’t exist but that provides the potential for manufacturers working on designs to agree on a common form factor. But cars are just too varied in their designs (in many cases even different models by the same manufacturer) and we’re only moving further in the direction of having battery packs integrated into the rest of the car’s structure for stiffness and reduced weight.
