Not sure about reliability of battery swapping. First thing is that one needs now 2 batteries per car while one battery is being charged somewhere. It’s technically hard problem to connect and disconnect 1000s of cycles coolant lines and thick wires to the very bulky and heavy object. While it works nicely in the demos with new cars it brings huge problems in the reality after couple years.

2 batteries per car is assuming everyone is charging at the same time. In reality there are people driving their cars while batteries are being charged and new batteries being built. The batteries charge time efficiency over time also plays a role as infrastructure scales. I wouldn't be surprised if we will see this tech in the US soon. Especially after we get back to a somewhat normal business environment with China. Next election I hope. Consumers win when they have more choice.

I'd go as far as to say it doesn't make sense except as an exceptional process, a battery upgrade or replacement due to manufacturing fault. Moving 300kg+ batteries around is just not very sensible. Maybe it might be possible for heavy plant machinery where removing the battery and transporting it to the charger is easier than transporting the machine back to the charge point.

There is a Nio battery swap station next to my nearest Tesla station (Lier South, Norway). No idea how well it works, but it certainly does work. According to Nio they had four million battery swaps in China by the end of 2021. Of course they don't say how many problems occurred.

I'd think you'd be charging the battery as normal 80% of the time and only swap when you're for longer trip. But yeah, that seems more viable for stuff like electric scooters/motorcycles, as the cost of infrastructure would be much lower.
