To me battery swapping makes no sense for consumer cars unless it’s used to significantly increase prices (possibly by removing home charging as well): battery swapping requires a ton more maintenance, space, infrastructure, and logistics, constrains vehicles enormously, and requires a very small number of standard battery formats.
NIO now has 9 battery swap locations in The Netherlands. I'm not sure this is better than charging points, but at least we'll get some data on it. Tom Scott has made a video[1] about it.
Oh battery swapping would be entirely automated, no way you'd do it at home (let alone on the reg).
Nio Inc. has videos of the process, and that's what you'd expect (and I assume what tesla tried at one time), you drive to a booth, the car gets locked in and the battery is replaced automatically, then you drive out.
In the NIO case, NIO owns the battery and you pay a monthly leasing fee. One interesting feature this allows is that you can lease a cheaper low capacity battery for the 48-50 weeks of the year you drive less then 100 miles a day, and upgrade to a more expensive high capacity battery for the few times you're driving far.
This map has real time stats on battery swap. Unfortunately it's only available in Chinese. NIO has done 35 million battery swap to date and you can see where the swap stations are located. Not quite as accessible as your gas stations but not far off especially in the large cities.
