Won't Charge on Level 2 chargers

[Sweetwater]

Not on my EVSEs or any I've researched so far. That diagram is from a generator's info page?

Then why didn't they just use NEMA 6-50 ?

The neutral is not used for 240 volt charging but if a 14-50R is installed the neutral must be connected to the power source or it is a code violation. It must be able to work in all conditions that use a 14-50 plug, not just for charging the car.

Some do. Some prefer 14-50 for future flexibility.

Yes I understand that. Was referring to hardwired EVSEs.

Because 14-50R receptacles are common in campgrounds.

I can confirm that neither the Ford Mobile Charger does not use the neutral wire when connected to a NEMA 14-50 240v outlet. (Also the Ford Connected Charge Station does not use the neutral wire). I also have a ChargePoint Home Flex and that does not use the neutral wire.

I don't know if wiring the neutral wire is required to pass code ... but I do know the EVSE's don't use it.

It appears that I have a one -off problem with respect to my MME not charging on any level 2 charger. After 4 visits to the dealership and after they performed TSB 21-2171 (as mentioned above) and after assuming that my home EVSE or wiring was the problem, they finally agree that the car is not charging. Apparently they thought the was charging before because their level 2 charger was providing the proper charging indication when my MME was plugged in. Also the MME charger light segments were illuminated and blinking indicating that the car was charging. And if you went to the main screen and opened the Charge page it also indicated it was charging. Not to mention that on my FordPass app, the app said the car was charging and gave an estimated time to reach the desired charge level (which constantly grew later and later with every refresh). The problem is that not 1 kilowatt of energy was getting to the battery despite all the indications from the charger and car and despite how long the EVSE was plugged in. It was the fact that after a 4 hour "charge" on the dealership EVSE my MME did not show any increase in range or SOC that forced them into looking deeper into my problem.

Now that we all agree that my MME is not charging I'm going to take it back to the dealership tomorrow (Monday) where they said they will need to keep it for a few days and try to isolate the cause (I'm sure with the help of FMC). Ironically the car will charge on the Ford level 1 charger but I noticed that my grass grows faster than my SOC on Level 1.

Comments welcomed.

Again, I think they missed updating the SOBDM module (the charger) the first time around since it's not on the sheet, make sure they double check if that's fully updated. Probably a human oversight.

I don't know if wiring the neutral wire is required to pass code ... but I do know the EVSE's don't use it.

If an EVSE requires a neutral wire to function, it's a piece of junk and needs to get with the program. 95% of EVSEs don't require neutrals, there's no good reason it would need one.

The electrical code says you only need a neutral wire if you install a NEMA 14-50R. If you install a 6-50R or hardwire it then you don't need one.

I'm just thinking a bit about the information flow when you plug the charger in. There are indicators that the battery is charging but the system that gives you a read-out of the level of charge is not showing additional charge. So one of those two read-outs is incorrect. Is it possible that the battery is actually charging but that whatever software/hardware combination that informs on the amount of charge is not working properly? Not that you want to go out and test that by driving... Curious to hear how this turns out and hoping you get it resolved soon!

Thank you.

Day 2 in the shop. I've received no updates as of this post.

One week in the shop and I have no updates. I got word from the dealership and Ford that they are "working with the Tech on the issue". That's it. No details.

As a former Systems Engineer I know what it's like to have to troubleshoot problems you have not seen before. But to keep the interested parties and people who managed the money informed we provided daily updates on our progress or lack there of. Waiting is not the hard part, not knowing what is going on is.

Week 3. Still waiting to hear from Ford and/or the dealership.

I have spoken to 3 separate Ford Customer Experience Specialists, all promised to keep me updated and informed as to the progress of my vehicle repair. But I have heard nothing as of this post.

Maybe this week ?

Have you started quoting them your state's lemon law yet? I'd find out how many days gets a car qualified. Might help motivate some action.

Thanks for the input. But damn I hate to go down that route.

Light a fire. Tag Mike Levine and Jim Farley on Twitter. Ask them if this is normal. Send the customer experience officers at Ford an email. Get in touch with the @Ford Motor Company people here.

And don’t rule out the Lemon Law for your state. You did nothing wrong here, you should have had some communication from the esker at least.

Did they at least give you a loaner? I have a reservation for both a Tesla Model Y and the Premium Mach E AWD ER which Ford informed me would go into production the week of 10/25. I will buy one of these two cars since the estimated delivery dates on both cars are very close. I am reading these threads carefully. Your experience is certainly giving me pause.

Charging is kinda basic; and you've done the right thing by measuring voltages of individual legs and been meticulous about following up. I am keen to see what Ford does with your situation. Three weeks is very long. I don't have an extra car at home to tide me over, should this happen to me.

No loaner. The dealership loaner option is backlogged and they have very limited inventory at the present time.

I did not expect my charging problem to be this much of an issue. The car runs great! And it charges on a Level 1 charger. I thought it would was a simple software glitch and a reprogramming would resolve the issue but I was apparently wrong. What I don't know at this time is if my apparent one-off problem is that difficult to resolve or if the Ford Tech hot line is overwhelmed with support request that I'm simply low in priority in their queue. Also, it would appear from checking my Ford Pass app via the vehicle "sleep" note and range and SOC data that my car was not touched for more than a week at the shop.

I bought the extended warranty which includes rental from first day on all repairs.
