My Mach-E won't stop charging after told to stop charging on Ford Pass App

[zvez]

My sense is that people are talking apples and oranges.

Apples:

The STOP CHARGING button in the FordPass app is NOT a STOP CHARGING BUTTON. It PAUSES charging, for a period, then resumes whenever the hell it wants to (as long as it's within your set charging hours). If you want to STOP charging before your charging limit is reached, you need to either set the limit lower, or unplug.

Charging to the set 85%, then charging to 100% (because someone hits CHARGE TO 100%), and then being done is exactly as it should work.

Oranges:

Vehicle has not reach it's limit, and stops charging on its own, within the charging hours. Then it starts again.


Am I not understanding?

It seems like the Emporia issue is the car reaches its set charging limit, stops taking power, yet the Emporia charger keeps trying and trying. That isn't correct performance, no. It should not try to charge when the vehicle is not asking.

this is actually not the case with my car (caveat here is my car has been plagued with the continue to act like it's charging when it reaches my threshold setting and is STILL waiting for a fix from ford). So the only way to stop the onboard EVSE from running (loud humming and blue light at charge port on) is to either unplug or hit "stop charging" in fordpass. I note when I hit stop charging it stays stopped and I come out next morning still plugged in but charging is off, no hum no blue light.

Tho in this case it's not important I have a juicebox 40, but it's strictly the source of energy and I don't use any of the "smart aspects"

I'm in my fifth month of having to do it this way.

Is the car really still charging or the EVSE is just acting like it is charging?
You have probably checked this but just in case...
Make sure the "Charge 100% when plugged in" button is not enabled under "Preferred charge times"
That would override your preferred times.

I used to use the stop charging and it would definitely "pause" at least overnight, if not a day or so. I did find that it would eventually start charging again, perhaps when the car 12v battery started to drain and it would check if there was a charger and it would start charging since it was below the limit, I am not sure.

But if @Homestead can test the behaviour of his non Emporia charger and confirm that hitting stop when below the currently set charge limit, the car will not restart, I believe that supports my claim the Emporia charger is behaving badly by tricking the car into believing it has disconnected and reconnected and thus starting a brand new charge cycle which then ignores the previous stop charge command.

I don't have an Emporia charger. STOP CHARGING works exactly as I stated, it will restart at some point. Might still be off in the morning, but give it time, it will restart.

Mine restarts in about 15 seconds. It behaves the same when the car reaches 80% (which is the setting on the car, not the charger). It retries in about 15 seconds. After 2 or 3 attempts (they shutters on the car open and close to ensure airflow...) it gives up.
My point of starting this thread was not to whine about the car, but to understand if my observations with the charger are seen by others. Given you have a different charger, your experience matches my expected experience with a charger, but not my observed behaviour with this charger.

Right. THAT Is not normal behavior. But others have chimed in with how things should work, and been incorrect about how STOP CHARGING works, which is what I was trying to clarify.

It's a software bug ford has identified on some 23.5 mach e. It's not actually charging the battery once it reaches threshold but the software isn't telling it to stop, so it thinks it's still charging. First time I charged it, it literally stayed in a charging mode all night. BUT fordpass also thinks it's still adding to the battery so you get an obscene kwh "energy added" reading on the charge status in fordpass. So the only solution is to hit "stop charging" or physically unplug

so mine stays off all night and past the charging window, I'm assuming if I left it plugged in it would restart charging that afternoon (if it wasn't at threshold percent) at designated start time. In other words it would resume the charge settings.

Correct. When the new charging window opens, the car will ask for power.

First of all, when you press the "Stop charging" button in FP, any normal person expects the charging process to stop. Permanently. But it does not. This is just the way the MME works. Maybe one day they will change it so pressing the button works the way we expect. But for now, it is just a pause, as Rick said.

Secondly, setting a charge limit should work. If it does not, you have a unique problem with your car.

And if the charge limit is reached, you should be able to start it again by pressing the "Charge to 100%" button. In fact, pressing that button should always override the limit and do just that. And it does, based on my experience. So if your car does not do that, maybe you have an issue the dealer should investigate.

Maybe when the charge limit is reached and the car tells the EVSE to turn off, the Emporia disconnects the AC and reconnects, making the car think you have just plugged in. But I have not tested this. Has anyone let the car get to the charge limit, unplugged the EVSE and then plugged it back in? If so, what happens? Is it the same thing the OP is seeing?

Personally I don't think any of this is a problem. The car charges as expected, and the EVSE delivers the power the car is requesting. Nothing to worry about, really.

Did a charging test with target level of 80%. It started charging at 9PM , when it got to 75% I stopped the charging. It remained stopped for about 45 minutes and it then started charging again on its own.
Finished charging to 80%. Charge Complete.

I wish Ford could chime in here and offer some explanation on why it started charging again. However, this is not really what I am interested in learning. I am specifically interested in confirming that others see the charger continuing to try to offer a charge when the car has stopped charging (either by pressing stop in app, or reaching charge set point), and if that can be fixed.

Ford doesn't ever chime in.

Hello @EmporiaEnergy, thank you for reaching out. I have the charger configured to max out at 40 amps already, and I currently have it set to charge at 18 amps. I do not use any schedules or peak demand settings on the charger, it just charges as soon as I plug it in. I do have a limit on the car to stop charging at 80% though, which is respected as far as I can tell. I tested tonight the pause function in the Ford app with my included Ford charger connected to the same plug. It turned off charging and stayed off. I did not leave it for a long time, just longer than my Emporia charger which when testing afterward, turns back on in < 1 minute.

Attached is a picture from my charge session. The red circle is where I pressed pause in the Ford Pass App, and as you can see, charging resumed quite quickly. While beside the vehicle, I can hear the vehicle stop charging, and then it sounds like the charger goes off. After a few moments, it makes another sound and audibly clicks back on; the vehicle then starts charging again.

Any insight you may have, or if this is a feature to ensure charging is not accidentally interrupted by a vehicle temporarily refusing charging, would be great.

Thanks

Hi OP,

Here are some extra insights that may be helpful:

Tapping the toggle will change the EV Charger's mode from Pause to Ready.

1. From the App Home screen, select your EV Charger by tapping the Electric Pump Icon
   
   located to the left of the charger's name
2. In the middle of the screen you see the toggle, the button that controls the charger: when it's gray, it's in the
   
   PAUSED mode, no power will be sent from the EV Charger and it will respect the schedules created or energy management features set in the Emporia App.
   
   It also locks the charger for unwanted users. When it's blue, it's in the
   
   READY mode and it's going to charge as soon as you plug into the vehicle (as long as the vehicle is ready to accept charge).

If using schedules don't forget to confirm your time zone, so the charger knows what time it is: https://help.emporiaenergy.com/hc/en-us/articles/9302857871895-Time-Zone
