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.
