Ignoring preferred charge times

[dimes4slim]

I have had an issue with my Mach E ignoring my preferred charge times at home. I deleted all locations, and added my home as the sole charging location, with the preferred windows being 10AM - 4PM, and 10PM to 5AM. The target is 80%, and I have no departure and comfort settings. This was all set up in the car (not through the app), but the car is still happily sucking my expensive California electrons off the grid after 4PM unless I manually stop it. I cannot find where there is anything that I can toggle to "charge when plugged in" or conversely "use preferred charging time" other than the charging locations toggle in my screenshot attached. I should add that it has worked occasionally in the past, but not with consistency. Thanks for your insight in advance!

I've had 2 instances recently that were odd for me............plugged in at about 32% expecting it to charge to 90% and it never started. Unplugged and it did start charging when the scheduled time came around. Couple of nights ago it started charging at scheduled time but stopped at 78% for some reason. unplugged and at scheduled time it finished charging to 90%.

I am really not impressed with Ford and their software expertise

The MME will calculate how long it needs to charge when you plug it in based on the EVSE power available. If it needs longer than your charge window allows, it will start charging immediately ignoring your settings. This is very common if you charge with L1. It will stop charging when it knows it can get to your target charge in the window and then start up again when you get to your charge window and finish the charge during the window.

In your case, since you have two charge windows, it may do its calculation only on the next available window and not consider the 2nd window. Also, if it doesn't seem to act as above, you might try adding your windows in the other order and see if it clears it up (ie. add 10AM-4pm first, then 10PM-5AM second). It wouldn't surprise me if there was a glitch in the software ;-)

It does this to make every attempt to get to your target charge SOC by the end of your charge window (with some buffer). The easiest way to stop this from happening is to use a smart EVSE that won't allow it. You won't hit your SOC by the end of the charge window (that might be ok) and it will start up and finish in the next window. You can also drop your target charge SOC so it will fit in your window for that day but that is a manual exercise and you need to remember to adjust it back up for the next window.

I like the way Ford prioritizes the target SOC over the charge window since this can affect the next day's drive, but it is not documented anywhere.

I've had one case where the location profiles were corrupted due to an update and deleting them and reinstalling them cured it.

I've had a couple of occasions where the J1772 charge gun wasn't fully inserted and caused no charge (usually the kids not plugging it in solidly until it latched).

I've had one case where an update failed and the charge didn't start up again after the failed update. It was fine the next night.

I've had multiple cases where the EVSE was the culprit and needed the circuit breaker reset. This showed up right off the bat with an error message in FordPass and I usually caught it early enough although very annoying. That EVSE is no longer in service.

2+ years and most of my non-charging incidents were not Ford issues. 2 were.
