Why does my Mach-E keep starting a charge outside the preferred times?

[933233311602]

I'm interested to see @jamesphw try a test.

If you keep your desired 11pm - 7am charging times but set your desired battery level to 50% (the lowest setting possible) does your car obey the 11pm - 7am schedule?

I'm curious to learn if the car is giving the battery level target a higher priority than the charging schedule, like others have suggested. That would be smart because, from the car's PoV, a battery charged to the owner's desired fill is more important than the charging schedule.

Maybe check the clock on the car. My dealer had set mine as PM when it should have been AM. It threw off my charge time calculations when I first got my car and was charging with level 1.

Necro-ing here, but I think I figured it out.

If you set your preferred times for, say, 9 pm to 7 am, the system will try to hit the target charge by the end of that window.

So in essence, your 7 am stop becomes your departure time.

Basically, for each "window," the car tries to reach the target by the end of the window. If it can't, it ignores preferred times entirely.

Really shitty situation for anyone without L2.

Couldn't you set your evse so that it is only available to charge at your scheduled times? I believe my evse allows that. I don't use a schedule because my electric is the same price 24/7.

@Jhonka I am aware of that feature, and in my case that's not it (I have an L2 that can charge the battery fully within the set schedule).

@Space_Pony Yes, most EVSEs have that. But I prefer to let the car control the schedule because a few times a year I need to charge outside the normal "off-peak" times, and I don't want to adjust the EVSE since that's much harder.

The good news is that this issue hasn't happened to me recently. I was never 100% sure about the issue, it could have been silently fixed in one of the software updates. I suspected it had to do with PAAK connecting to the car, and I also reset my PAAK.
