I normally charge at home, but with a mostly empty car I noticed that the Volta free charging near me was open, so I parked there and filled up. When it was ready to go I walked back and there was already someone wanting to charge. I pulled the J1772 and hung it up but when I tried to remove the adapter it was locked. I know, now, I should have stopped the charge BEFORE unplugging.
I tried unlocking it with the touchscreen but the only control was Close Charge Port.
I've had this happen on my Model S a number of times. Yes, there's a console command to unlock it. There's other ways, as well: in the "Remote S" smartphone app, there's an unlock command. I believe that they sometimes had that command in the official Tesla smartphone app, as well. In addition, did you try holding your HPWC plug next to the Model 3 socket and either holding the button to release or pressing it? I believe that is another way to release it. Finally, on the Model S, I believe if you hold the proper button on the key fob (the charge port button?), it will unlock that port.
In addition, I did start practicing taking it out with the J1772 plug, which I did get better at, but for some reason, stopped doing religiously, and I ended up pulling the plug out manually a lot, using many of the above commands. I think I ended up doing it after pulling the J1772 because it was easier to do that way (easier to pull out the J1772, then get the adapter after). Obviously, that depends on the unlock command working.
Obviously, the Model 3 is different because you don't have a key fob with buttons, but I would like to know if the button on the HPWC plug (I remember having to hold the button) or the Remote S app command work when this happens again.
I find it amazing I remember all of this stuff after almost a year of not owning my Model S.
