oh god. I know this one so well. Part of it is a Gen4 (mid 2020-present charge port ECU) issue. Other part is common to Gen3 (Model 3 start-of-production through mid-2020) and Gen4.
One problem: it slaps the door shut on your hand if it "doesn't like what you did". It's done this for YEARS and it's never stopped being annoying, because it's a simple thing to "not do". It does it if you pull the plug out before it's Fully Satisfied. And if it does it with the Tesla plug, too -- you know, the one where the car controls whether you can pull it out or not?! Yeah.
Come on. 100% buggy as heck. That should not happen.
With J1772, the problem is much easier to trigger... you just
grabhandleandunplug in one action. Oh it HATES you doing that! Guaranteed way to get an "angry charge port door slap-shut" response from the car. You'll also probably notice that if you have a door open when you do this, you get the "boop boop boop" noise from some kind of fault being reported. The charge port LED also turns red. Oh it's
a n g e r y . It shouldn't be... it got the prox signal saying the handle's being unplugged, but lord have mercy if you unplug it before Tesla's industry-leading software responds to cleanly stop charging like ... any other EV out there can do without issue
Second problem: if it closes the door on your hand/on the J1772 adapter, it should re-open if it notices it can't close. This is solely a Gen4 issue. Gen3 (prior to mid-2020) would politely re-open the door if it couldn't close all the way. Gen4 is just like "
Welp, we live like this now" if it can't close the door all the way. And you have to go into the car to say "open door" (and hope it's in a mood to actually respond to the button in the car) to get it open / get your adapter back. There's a potentiometer inside the door hinge that tells the charge port ECU (the "Gen3, Gen4" thing) what position the door is at. It KNOWS it's not fully closed, but it CHOOSES to stay that way instead of re-opening. That bugs me the most in my Gen3->Gen4 retrofit project... my charge port used to be smarter, now it's dumb
And again, both of these are simple issues they could fix if they spent just a few minutes on it. That's why it bugs me. That, and the LEDs on the charge port going out after you walk away (though I haven't tested this in months to see if it still does it). So, to passers-by, your car looks like it's not charging, if you're charging in public. Still no hints of a "public charging mode" switch to, say, keep the center display showing the big charging display, and keep the charge port LED(s) lit. (grumble, grumble, chasing FSD and robot squirrels...)
