Problem with “Depart at” charging

[FatherTo1]

Knock on wood, but I haven't had any issues with the scheduled departure. Off peak ends at 6:00 for me and I depart by 7:30.

I use both settings. I have the charge time (off peak ending time) set to end at 6:00 and the departure time set for 7:30. My car finishes charging by 6:00 and ready to depart by 7:30.

@Jughead135 check the charging time. After the latest update it reset to 00:00 and as soon as I plugged in the car began charging.

This is how mine used to work prior to the ability to set when off-peak ends. However, this was still less than ideal because it gave two hours for the battery to get cold again and i wouldn’t have full regen when I leave at 8am. In the Summer this would not matter as much but in the Winter I wanted both the battery and cabin warmed up when I’m ready to leave. Otherwise I’m using more energy on the drive to warm up the pack again.

I've had the same problem with charging starting right away, when no peak rate end time was set up on the car. I don't have TOU rate schedule for my power, and the only way to make the car delay charging till closer to my departure time was to set the end of peak rates later than the scheduled departure.

Ahh...! OK, I don’t have any off-peak rates set, either (since they don’t apply). Will try it!!

To be sure I understand you: If I plan to leave at (say) 8:00 AM, I would set the end off-peak time to (say) 9:00 (so long as it’s later than the planned departure time)? My desired result is (a) battery starts charging as required to get to the designated charge point at 8:00; and (b) car starts conditioning the battery and heating/cooling the cabin, as required, for that same 8:00 departure.

EDIT: That looks like what @Duffer is saying. Away from the car for a few days, will try when I get reunited!! Thanks!

I don’t think I would pay $45 for the stats app either. I guess I was fortunate back when I got it, it was considerably cheaper.
It is a very nice app and opens many things you can’t do with the OEM Tesla app but that’s just too much IMO.

You might want to try setting it up again. It seems to be functioning better after the last two updates, currently on 2020.48.30

When I woke up at 6:00 this morning the pack was already charged and the interior was 40° (outside temp 37°). The interior was 68° and I had full regen when I departed at 7:30.

It used to work in my M3, but with the last update, I’ve tried it twice and it failed twice. I just picked up my ‘21 MS Monday, I haven’t tried the departure yet. I don’t use peak rates as it doesn’t apply in Montana, maybe it’s still trying to use them and that’s what’s messing me up?

This is just another one of those things where it will probably take Tesla like 4 firmware releases to fix, cuz their development team has no real connection to the outside world...


Earnings call is happening soon. This is our chance to get Tesla to make an official upvote/downvote feature request portal.

Exactly - I found that as long as I set an off-peak end time later than my scheduled departure, it would not start charging when the cable is connected and instead use the scheduled departure time to decide when to start. However, I started wondering about phantom energy use (i.e. not measured by the car) for the pre-conditioning cycle that is activated by Scheduled Departure. It seems that the primary benefit of that process is to improve the amount of regen braking available. I decided that since my car is kept at around 8-10C overnight, it doesn't need to be pre-conditioned as long as I'm always able to regen to a full stop without wasting kinetic energy by applying the brakes. Now I use the scheduled charge start time option and take whatever charge it gives me by my departure time. Since I don't leave till late morning, I can always start the charging earlier from the app when necessary. I then turn on cabin heat remotely 15 mins before I want to leave. It's a bit more work but I believe it reduces total energy use.

Just had the chance to try this--and, yup, that's what's happening. Completely non-intuitive, but not a terribly difficult work-around. I guess the design theory is that unless there's an off-peak rate, you always want to charge immediately...??

Thanks again for the pointer!

Why is it so difficult for Tesla to introduce a simple setting like:

I want charging to START at xx:xx and STOP at xx:xx.


By the way, what it’s also very needed is to be able to change charging current (Amps) from the App. You can only from the car.

IMO, all charging settings should be accessible via the app....

Fart noise improvements higher priority

I used the pre-conditioning/Depart-at settings and they seem to work well. I just usually have to remember that if I want the car to charge before I leave for work the next morning, I have to go into the app and have charging start manually. If I don't plan on driving before my scheduled departure time, I just let it do it's thing and it has worked so far.
