Charging Errors

[Oregon owner]

Our Mach-E went to the dealer for the update and ever since then it stops charging ever single time we plug it in-- sometimes it charges for 5 minutes, sometimes for hours, but it always stops on its own. We took it back and service can't figure out the problem and they said they're so busy they can't do anything until we bring it in for the 2nd and 3rd recalls (on the glass windshield and moonroof). What kind of service is this? $50K for THIS? I've been trying to charge since 5:30 pm yesterday, it is 8:27 am and I'm at 62%. We've gone out and un-plugged, re-plugged so many times. This is exhausting.

Based on your description it sounds like a car issue. I do not have my Mach yet so I can not be of much help. Can you share additional information so that perhaps others on the forum may be able to help? What type of charger and what error message are you receiving may be beneficial. Also have you power cycled your charger? ( probably not the issue but I would at least try it.)

Can you provide more information... What charger? When did you get the car? What's the vehicles build date?

It sounds like this is a new car, which wouldn't have those recalls. It could be that if using the Ford charger the plug at the top of the charger isn't seated properly, which commonly causes the issues that you are describing.

It will be charging and then I get a notice that "Scheduled Charge Did Not Begin" even though we have it set to charge when plugged-in. We have no schedule or delays on it and that is how we've had it set since the day we got the car. The only thing that changed was taking it in for the update. We un-plugged the charger from the wall and let it sit for several minutes and re-plugged it and it didn't make a difference.

We have a PRIMECOM charger (as Ford had pulled their charger from the market when we got our car delivered). We got the Mach-E last March (2021) and didn't have this problem until January 2022 when the car went in for the system update.

I can't point you to a single person who I know that has a Primecom charger but if it was because of 21P22 then I would start by eliminating other EVSE's or possibly a public charger. 21P22 did have updates to the battery control modules and charging modules. My guess would be that it's the charger, but go to a public DCFC or L2 and test it there. If it works then you know it's the charger. If it doesn't then yes it would be the car. Just use a process of elimination.

Why would you guess it's the charger even though it worked reliably until the day the car came back from Ford with the new update installed?

Because the charger firmware can sometimes have issues with certain cars. The reason I know this is because my previous EV had issues with a ChargePoint Home Flex. I called chargepoint and they said that the firmware they pushed had caused issues with my EV. They had a fix that they pushed within a few hours and the issue was resolved.

It doesn't hurt to just use process of elimination. It could be the car and I'm not saying it's guaranteed to be the EVSE. It's just an easy way to eliminate one or the other.

Do you mean the CAR charger/plug, not the PRIMECOM charger? That is what I think and why I'm so frustrated with the service department. It always begins to charge just fine-- it's just that it stops after a while. That is hard to replicate away from home.

I don't think it's the charge receiver on the car, although you can inspect it to make sure there's no obvious damage. There is one thread where someone did have a receiver that was damaged, but I've only seen that once.

If the dealership looked at the car and saw no DTCs then it would lead me to believe that it's the charger (EVSE - Primecom) stopping the charge. If it was the car you would get a fault warning from the car and the lights to the right of the receiver would be red. A fault warning is not "Scheduled charge did not begin".

Does it do the same thing with the Ford Mobile Charger?

 

[Oregon owner]

Actually we do have the slow charger that came with the car. We never use it becuase we got the fast charger, but I think we will try it today just to see. I hadn't considered this before--thanks.

I went to the dealer and got the updates too, and have been having problems charging from a wall-box (SyncEV). It works if I plug it in and let it charge straight away, but if I schedule a charge (on the wall-box app), while it’s waiting to begin it will fail with the same “scheduled charge did not begin” message. Car has been to Ford and they got a DTC saying irregular/erratic control pilot signal. So they have sent me to talk to the charger people instead (though it worked fine for three months before the update).

I even get the same message if I plug in and charge straight away but schedule it to stop at a specific time, the message comes exactly 15mins after it stops. I think the update has reprogrammed the triggers for the error messages. I’ve been getting a lot of “accidental unplug” messages too.

I’m going to copy the link to this thread as I’m going to send them to Ford to show how many are getting issues. @Ford Motor Company this is another example of the same issue.

Thank you! I haven't been impressed with how Ford has dealt with this--it feels like they're blaming outside products when it's clearly related to the update.

Every time I've seen similar issues it's because of the charger. Here's two examples where the person changed chargers and never had the issue again:

There's J1772 standards which change. Updates to the car can bring the standards and compliance to date. If the EVSE isn't updated and current it can have issues.

Until you can try another charger to verify the problematic device it's really futile blaming either the EVSE or the Car as you have no evidence of either being the cause. We can only go based what other's have done to resolve the issue.
