BetterPlace had it. They sold around 700 cars and had some stations in Israel. The idea was a bit too early (2013) and the battery tech was in its infancy, maybe now it can suceeded?

It only works if you lease the battery. And if you lease the battery, you care much less about doing all the things that keep you from trashing it. So either you now have to also lease the car (with plenty of surveillance) or the company has to write off batteries at a high rate.

  Isn't the main thing that trashes the battery fast-charging, which is eliminated by this scheme?

    > Isn't the main thing that trashes the battery fast-charging For LFP it’s actually leaving the battery in a high state of charge [1][2], though specifics come down to battery chemistry.

      After reading the paper the effects of leaving it in a high charge state seems to be smallish. The insideevs.com article never says what the size of the effect is, which is a hint it might be a lot of clicky writing about a nothing burger. In any case if you are the leasing company, you get to control the BMS. The BMS holds the keys to the kingdom. It can control how the battery can be used: charging rates, max charge, how long max charge will be maintained before it self discharges, min charge, allowed operating temperatures. It seems to me they could mostly eliminate the sort of abuse that seems to concern you.
