> it would make sense to be able to disconnect someone else’s car
This seems like a bad idea for something designed by for use in public with no direct supervision. I would absolutely prefer that no one disconnect my car over having the ability to disconnect someone else's car. I can understand having some override that requires a little mechanical effort in the case of malfunction, repossession, or something like that. However, I wouldn't want any random person to be able to disconnect my car at their discretion. That is a recipe for chaos at charging stations. Plus the caveat of "once its fully charged", already means you need to let the car have at least partial control over the unlocking mechanism anyway.
There's already a two-way data flow in the standards, so the charger could just ask the car to unlock if someone requests that at the charger. It does make sense for it to be a request to the car and the car can know the driver's preference on desired charge level (should be at least 80% charged, for instance) and/or alert the driver somehow that the request has been made.
