Home Level 2 Charger Issues

[@kWhpony]

It is my belief that there may be multiple issues that are causing the same symptom of not being able to charge from home. To date, it seems like for me the Ford engineer is focusing in on why there is a lower voltage rate coming from the 12-pin on the EVSE that is not waking up the BCM but the same low voltage rate on the 12-pin connector with 120V is not an issue. I am going to be following up today with Ford to see where they are at. I am also under the belief that some of us are having charging conflicts related to software corruption (of the departure schedule). However, a few members have had their cars module firmware reset by the dealer and that did not fix the issue.

Just got off the phone with my service manager to get an update on the case that was opened for me on Monday with their hotline.

Within 24 hours the case was acknowledged with the reply that it was "under investigation" and did not provide further details. I asked the manager when it would be appropriate to escalate to the dealer owners and his reply was that we are " a long way" from that.....not exactly giving the warm & fuzzy feeling that they are advocating on my behalf for a new vehicle advertising level 2 home charging.

Yep

pretty much. (see screenshot). I just encountered this problem today. Everything worked great 2 weeks ago (my last home charge),.

I heard back from Ford. They are replacing my Battery Control Module. It’s a two-three week lead time for them to get the part. I am not 100% convinced they know the exact issue but based on what the Ford engineer and Mach-E team is seeing, this is what they want to try. Guessing if this fixes the issue, there will be a path forward with people that have a similar issue. However, I think that some of us are also having a software issue relating to a corruption in departure schedule charging but that is my own suspicion and Ford does not think that is my issue.

Anybody know where the Battery Control Modual is. Do they need to open up the front end to get to it. I am not happy with the proposed solution. Did a bunch of us in Illinois get the faulty parts. Really! Doesn't make sense to me. Well I guess if that fixes the problem so be it.

So, I need to measure the voltage at my 14-50. But I'm in IL, I took possession of Mt MME two weeks ago. I've charged at home twice, both without issue. Once was using our Juicebox Pro 40 and it charged to 100% overnight on a Friday, I believe. And then it charged to 90% (after I set up a charging home location) using the included mobile charger on a weekday.

Also, my FE MME was built 12/26/20 and I picked it up out of state in MI.

I'll reply back when I measure the voltage.

Some people said it worked fine for a period of time and then stopped, so that could still happen to me.

Good question. Not sure if they need to take my car apart. Guessing it’s somewhere towards the front of the car versus rear.

Mine worked twice but I was having issues from day 1

You guys that are affected by this should insist on dropping the car off at the dealer and request them to fix it, and let them know that you will pursue a lemon law buyback if it is not repaired in 30 days. This will spur Ford to quickly fix this issue once and for all. From their response seems like they are going to take their sweet time changing parts one at a time which will all be on backorder - it shouldn't take more than 2 days to have a battery control module sent overnight for the repair.

All of you who are having this problem should also put pressure on Ford through social media to forgive some or part of your monthly payments. The inability to charge an EV in ones own home is a very significant flaw in the operation of the vehicle.

I would ask the dealer service department. There are some electronics control module in the front of the vehicle, basically under the removable access panel you see under the hood. But I'm not sure whether any of those are the battery control module.

If they can't get a fix would we be eligible for them to get us a whole new mach e ?
It really feels like an ota update or even an update on fordpass could possibly solve the issue since that's where it seems to lock up.

Also had an interesting note yesterday when I tried one of the members steps on switching the 120v to 240 volt charging. When I made the switch over after stopping the 120v charge, the noise being made while charging kept going like it was going to start charging on the 240. Even after I unplugged the 240 when I realized it wasn't working the noise was pretty audible for about 5 or so minutes. Not sure if it means anything but kind of weird.

Wonder if someone put a 240V AVR on it in Illinois if it would help? Not saying everyone run out and buy an AVR but it could provide some info about voltage and/or dirty power if someone is up for it.

I am getting between 244-248V and 60 hz frequency. It’s not the power. Based on what they saw on my set up is that the 12 volt trigger pin on the EVSE is a lower voltage then they expected. This is what communicates to the BCM to tell the car to accept the charge. The 12 volt trigger pin also measured low on the 120V charge but the BCM was accepting the charge. This is why they want to replace the BCM. This also correlates to your theory of why quickly switching between the 120V and then 240V is producing strange results. The BCM seems to be less sensitive when getting the 120V.

Interested in your thoughts as well as others who are experiencing the home charging issue.

How should we approach our respective service departments with this information to get our BCM as quickly as possible instead of waiting the 2-3 weeks for yours to arrive, learn that it works, and then have to wait another 2-3 weeks for our vehicles to be repaired?

Just curious: Does anyone who is experiencing this issue have the Ford Connected Charge Station in their home?
