Book a swap in the app
arrive in the lineup.
serves one car at a time like an oil change
the station has to constantly be charging the used batteries.

Install 4-6 high speed chargers in the same spot and clear more cars faster .

Essentially the swap station is only better if you arrive without a lineup. The swap takes 7-10min and is manned. If you are one or two cars deep waiting you are better to have just found a charger

Why wouldn't you compare like situations? It appears you chose a rather well set-up charging station vs. a poorly setup swapping station.

I didn't picture an oil change when I imagined a battery swap station, I am not sure that should be the default or starting point.

neo is the ONLY company doing swap stations, and that is how they work.. I also described current, available EVs with available chargers.

True, mass parallel charging can fulfill more peak demand faster, but from the point of view of the user, it would still be good to have the option to fill/exchange the battery quickly.

An EV6 on an capable fast charger can do 10% to 80% in 17 min

They need to make the swap faster / higher throughput or charging is still going to make more sense .

One thing that would speed it up would be if you could just drop the 1-ton battery by gravity (safely, which I understant is hard on the edges of any hooks holding it, maybe they could use a raised floor, which is what they do in NIO) and snap it back on in 30s or less for a total of 2m. The rest is just your usual parking, pulling the gas hose. Maybe make it go-through so you don't have to manouver into place.

More like install 8 to 12 DCFS at a minimum and some very busy stations have a massive amount of chargers.
