Car charging to 100% when set to 80%

[Kathysmustang]

Ford advises keeping car plugged in during cold weather and we live outside Chicago so we decided to do that.

Set my charging time for 10:00 pm to 2:00 am up to 80%. Plugged car in at 5:22 pm at 52%. No departure times are set. Received message that the car would need to charge beyond the set times.

Woke up this morning to find the car had charged to 100%. Anybody know why? I know the car is not supposed to sit at 100%. Thanks.

This happens to me sometimes. I find resetting the charging location seems to resolve it. Quite annoying though!

This happened to me once, but much better than not waking up to charge. That happened twice. Really bad feeling when you have to get to work and find out that you don't enough charge to there.

Delete your charging "location" and set it up again.

There have been instances where over the air updates dorked up those charge settings (happened recently with Lightnings) as well as messing with profile settings.

Just delete and set it up again.

I am not sure about this but perhaps it had something to do that your charge window was not sufficient to reach your charge parameters. So your car charged outside the charge window and went to 100%. I am not sure this is a normal response or not but something was going on from the start when you were notified the car would need to charge beyond set times.

Two issues.

1) IF your charging window is too short (at least the car thinks it is), it will start early to be done. So whether it's an 80% target or a 100% target, the car figures it can't finish so starts early. If you can, extend your window. Note - if you're using the 110v adapter for the Ford Mobile Charger, it will almost always ignore the charging window.

2) Sometimes an update deletes the saved location. Charge for a few minutes. Unplug. Save location, reset times and percentage, then try again.

As noted, assuming you're L2 charging at 32amps, you'll need a bigger window. I'm outside Chicago as well, on ComEd hourly pricing, an have it set for 11AM - 6AM, and it completes between 2AM and 4AM most days.

There have been a couple of occasions where I'm near 20% (slightly above or below) where it charges outside that window, but as noted above, I believe it's trying to get you closer to your target charge.

I've had the 100% happen to me a couple of times; it corrected itself on the next charge.

A similar thing happened to me. I think I failed to “Save” my charge setting at 50% when I changed to the lower % after a recent 100% charge. I’m trying to remember to scroll to the bottom of each page to make sure I don’t forget a step.

A few times when I thought the car had messed up I later decided it was user error.

When you plug it in does it start to charge right away? Does it not honor the charging schedule at all or does it charge to 100% starting at your specified time? Mine has been telling me about the window also lately but it is and has always been adequate. Warns about out of set times but it charges at the scheduled time and to the correct % charge. It charges L2 at around 8KWh and the ER battery is 90 KW for 100% to get a conservative feel for the time window.
