Is charged scheduling broken?

    I have my scheduled charging set for 2AM. I keep my daily at 90%. Yesterday morning I drove out to do some chores, came back with 87% charge. I came home, plugged the charger in since I've always been told a plugged in tesla is a happy tesla. I went back out around 10:30AM PST and noticed that my battery was back to 90% again. Odd. After I came back home around 11:50AM ish, and plugged back in, I noticed that charging was going on even though my schedule was 2AM. The only way it would reset was if I went into the charging screen and moved it from 2AM to say 11PM. After that, it was set to 11PM. I reset it back to 2AM since I don't need to charge that much and that is during off-peak hours. This morning, the same exact thing happened.

    Is charged scheduling broken, or is there some time range where it says it will continue charging for a certain amount of hours? I thought it would be between my charged scheduling and the time I set to leave 7:30AM PST (which is only set to weekdays), but that doesn't make any sense why it would of kept charging when I came back in the afternoon.

    Anyone seeing the same or can tell me how this is supposed to work?

    I've tried rebooting the unit already.

    I may be wrong, but I believe you need to schedule the charging each time prior to plugging in. That is the way I do it and have never had a problem.

    Hmmm, I’ve only set my charging to start at 2 am once, and it has always remembered after that. Tesla’s use GPS location to ‘remember’ the settings for a charging location, perhaps something is interfering with that? Several things use the same mechanism, including folding/unfolding the mirrors, the amperage to use for charging... Are you seeing odd things with those.

    I have an Aug ‘19 build SR+ Running 50.7 and an HWPC to charge it, never had a problem.

How reliable is your power, because a power drop will make it mad and sometimes start charging when the power comes back...

    Is there a weekdays only setting? I think that one tripped me up once.

    I’ve had problems where the car keeps charging to 100% even though I set it to 60-70% when I use the departure setting. Like it reaches 70%, then all of a sudden its charging again and overrode the previous limit. I posted on here but people were just saying that I moved it accidentally. I since put the schedule to start at 9pm and don’t have this problem.

    Isn't the charge time a start charging at/after time? And pretty much all day is after 2 AM... Ok after looking the Model 3 manual it is sort of that way:

    So it shouldn't have started charging at 10:30 AM when you plugged in.

    That’s not right. You set it once only. Set mine to 7:15 am when the feature came out. Never touched it since.

    I saw the manual after I posted as well and agree it shouldn't have started to charging when I got back yesterday. My only guess is that the setting wasn't saved for some reason.

    I decided to set the time 11PM and will monitor. I drove back today and it didn't charge, so maybe something with AM settings is confusing the system. I've never had this issue before.
