I have an Emporia charger plugged into a Nema 14-50 with 50 amp breaker maxed out at 42 amps, though I set it a bit lower. The vehicle was charging, when I went into the Ford Pass app and looked at the charge details and selected 'Stop Charging'. I have a real time power meter in my house, and was able to see the power usage dropped. A minute or so later, I noticed the power consumption went back up, and I looked on the app and it started charging again. When I was using the Ford charger on my plug, or a 120v plug, this would never happen (though it would seem to start charging again at some point in the future without intervention, but never after a minute, it was usually a day or so).

Has anyone experienced this and been able to address it?

STOP CHARGING is a pause. You then need to either disable the charger with its app, or unplug the car.

It wasn’t previously. I am not exaggerating when I say it starts charging again within 2 minutes. A pause doesn’t make sense and this is not how it behaved previously. I will need to try the ford charger I guess.

And that makes absolutely no sense. Stop charging should be stop charging not pause charging. Freezing temps and run out and unplug it is the only way? Guess it is what it is good to know.

Seeing that OP is in Canada, could it be the car trying to keep the battery warm since it is plugged in?

I'm curious why you would stop charging before it is completed. I've never hit that button. I have stopped charging by disconnecting to go somewhere before completed. I'm sure there's a logical reason.

My Emporia will start up again but like you said, not after a minute. When the temps were below 20F, it was adding power for about 15 minutes, at around 7 hour intervals, presumably to keep the HVB happy. The interval got longer as the average temp approached 30F, and then it stopped.

OTOH, FordPass thinks I've added 780kWh over the past 4 days...

Typically it is because I don’t want to charge and discharge repeatedly, even if it is better for the battery overall. If my car gets plugged in and I am going to go out and then charge afterward, I may stop the charging.

Either way, the button is there and it previously worked as expected. I will have to try with the Ford charger, I believe the issue is the Emporia charger basically disconnecting and then reconnecting and the car thinks it was replugged and resumes charging. I will get my evidence later today.

Hi OP, we have some thoughts and insights for you that should help:

If you're using the NEMA plug in a 50A breaker, your max charge rate should NOT exceed 40A.

You can control the Emporia EV Charger from the Ford App or from the Emporia App. When you set your breaker size to 50A in the Emporia App, the max charge rate we offer in the Emporia app is 40A.

If you're using schedules, we recommend having schedules only in one side, either in the Emporia app OR in the Ford App:

To have the schedules working in the Ford app, the toggle in the Emporia App should be in READY. To having schedules working from the Emporia App, the toggle should be in PAUSED.

Here's some detail about the Emporia App related to this.
The toggle is the button that controls the charger:
  • When it's gray, it's in the
    ?name=inline-1823147794.png
    PAUSED mode, no power will be sent from the EV Charger and it will respect the schedules created in the Emporia app or other Energy management features set in the Emporia App. It also locks the charger for unwanted users.
  • When it's blue, it's in the
    ?name=inline-847786250.png
    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 is it!

keeping in mind that my 23.5 gt has the charging issue, but when I hit stop charging (the only way to stop the onboard charger from staying on, that or physically unplugging). I've left it plugged in after hitting the "stop charging" on fordpass and it stayed off.

Again it might be different for cars that actually have normal charging function (still waiting on the long promised OTA from ford on this)

Early on, I used the “Stop charging” button twice. Both times, it restarted. I don’t recall how long it stayed off. I don’t use that “feature” any longer.

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.

One final note on this, I was able to catch my vehicle charging to 80% when the vehicle stops charging. The charger appeared to “retry” twice by disconnecting and connecting again. The vehicle starts the charge process and opens the shutters at the front and closes them, then starts charging only to realize it is already at 80% and then stops again. This happens one more time and the charger gives up.
If we could get a toggle to disable this retry mechanism that would be great!

Attaching another screenshot showing the retry attempts as small power usages along after completing the charge.

The EVSE is controlled by the car, and the car is turning it back on, not the Emporia EVSE. It is just responding to commands from the car.

Normally charge my car to 80% and never ever have a problem. Last night charged to 80% and noticed this morning it was at 85%. This was after 6.4 OTA update earlier in the evening.

will check in a few days if corrected or still an issue
