Home Level 2 Charger Issues

[Brademcee]

Good Morning,

Just figured I'd update for my particular situation. I have an FE that initially wasn't charging on 240v at all (home or work) but was fine on a standard 120v THEN stopped charging at all from the EVSE but would charge on public chargers fine. We had our car at the dealer for the last week, it was determined it was the EVSE and they gave us a replacement. It works on 120v fine both home/work, but it won't charge at 240v at our home but will charge on 240v at my work. Ford pass seems to be functioning fine and the car seems fine so chances are something is up at home. I will update if I ever figure out the issue.

You are experiencing the same issue as many of us. Issue needs to be resolved by Ford.

More evidence of a possible software glitch relating to charging/location interaction.

Did you measure your voltage at home?

Not necessarily. Commercial power is typically 208V while homes are supplied 240V. The electricians I spoke to all confirmed this. IMHO, this explains while those of us that are using power at work with the mobile charger report it functioning properly. Unfortunately I don't know anyone that has a 240V NEMA 14-50 outlet installed at home to prove or disprove the location interaction theory. One of my wife's friends has a hardwired Tesla connection, but I've been reluctant to spring the $150 for a TeslaTap adapter. If this goes on much longer, I may have to revisit that.

At least a couple of people reported that their MME will not charge using an EVSE at their home that worked fine with their existing or previously-owned BEV.

Just to pick a nit: Commercial power is only 208V if it is a 3 phase supply. Most are 3 phase, but not all. I would expect all decent size car dealerships to have 3 phase.

You're welcome to try my 14-50, if only you weren't 250 miles away!

I'm not saying it can't be voltage-related, but if it were, I'd expect the problem to be more widespread.

just wondering how am I able to charge at home on 240v both on the ChargePoint and Ford charger with voltage 250-257v on weekends for 5 weekends but not on weekdays?

Too bad you're downstate. I'd try to test with you in a heartbeat. I still feel like this is a tolerance issue with voltage thresholds, but of course, I'm not a Ford engineer with data points to study. I've taken all the locations out of my FordPass app, removed it from the phone and reset the sync from the car, and put it back on without any change. I'm not seeing the 'charge settings conflict' error on the screen anymore, so it's highly possible this is a location issue, but I can't understand why that would be. Hopefully we have an answer and fix soon. Five weeks into ownership I figured I wouldn't be dealing with this anymore. I was wrong.

It certainly seems like your car has some kind of phantom charging schedule that it's following.

That makes no sense at all, and your case makes it sound like a location issue with the charge settings that's somehow embedded in the system. I agree with @generaltso. It's almost like someone had the vehicle already and set it for optimal charging times at a lower cost on weekends.

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.

I just read through all these posts as well since I have the same issue. I’m in Illinois (Park Ridge) and had the car at the dealer overnight- they didn’t find any issues (no surprise there). I entered my info in the spreadsheet and hopefully there is a solution soon. I’m going to call Ford again tomorrow to update them since I have a case number established. I’m sorry we’re all experiencing this with our otherwise awesome cars!

I have a shop here in Skokie where I charge my car. You are welcome to come by and see if it charges here. PM me.

At my shop its a 240V single phase 200 amp service exactly like I have at home. My neighbors Tesla charges fine at his house and mine. My car wont charge at his house or mine. It will however charge fine at my shop. I know my electricity at home is bad. I'm an audiophile and spent 7k to purchase a PS Audio power regenerator to clean up the power. (huge difference) The regenerators meters show how much distortion in on the line and cleans it. It also brings the 128V down to 120V and locks it at 60hz. I think maybe the AC to DC converters in these cars are sensing something they don't like as they do recognize being plugged in and just wont charge at 240V. Hopefully Ford will figure this out soon as we have to be able to charge faster at home. Maybe they could give us one of their hardwire units to try at home to see if it works.

The idea is to set profiles by location. For each location you can set charging times and levels. If you're not at one of your stored locations, the car's current location should have no effect on charging.

One of the speculations is that the problem these folks are having could be related to these saved locations. I don't think anyone said that it was necessary for the car to 'know where it is' to be able to charge.

Let's wait and see what the problem/solution actually is.

That's is all good and understand but it does phone home numerous times after it is plugged in and has that location marked and running. Then it gets confused to where it is and reset that location while in the middle of a session and will do that numerous times if corrected.

The charging sub-routines could be firewalled off from the outside world once the charging schedule for that charging location starts and gives up that control when unplugged.

I have no idea why the charging schedule sub-routine has to check so often once plugged in. The Logic makes no sense and they could save a lot of problems with the charging schedule if they just make a successful connection for that location (I get it to hold for charge) and then firewall off the charging schedule from the outside world until unplugged as no further outside involvement should be required. Sounds simpler than phoning home multiple times to see if you are still plugged in at the same location you plugged in at and causing scheduling problems. Maybe they are looking for data (cache it and send when unplugged).

Always something worse then your problems and I can charge at 40 amps every time I have tried to (Grizzl-e extreme). Charging schedule resets after phone home and charges immediately and to 100% for me. Feeling for you guys and understand the frustration no 240V charging must cause to your schedule.

I also believe there is likely more than one cause to this.

One reason that it might be showing up more for one utility supplier than another (e.g.: Illinois) could be that some suppliers may have larger voltages or 'dirtier' power (higher total harmonic distortion). You might have a high THD which is why you needed something to 'clean' it for your audio equipment. The issue might be that Ford just set their tolerance too tight compared to other EV makers. That could be a reason why it works at the same location for some cars and not the MME. Cities with older infrastructure are likelier to have older equipment that wasn't upgraded to meet the more recent demand or wasn't properly load balanced.

There could also be a corrupt schedules issue where it could otherwise accept the charge.

For the record, I'm not having this problem, only trying to help where I can. I am in the camp that believes the problem is related to a bug in the location services and how they are used for charging, not voltage.

At least one person did not have a problem until after his house was established as a location, and a different MME from the dealer charged at his home without issues.

Commercial establishments use 3 Phase supply which an out of 208v and that is probably why it is working at your work. Residential supply is single phase and 240v. This aligns with what my EVSE installed told me. He was pretty sure that it was because of the >>240v situation.
