Except i've yet to throw a code no matter how hot I get the handle/port so far.
You won't throw an overheat code with the current software because the derate kicks in first. In the previous software, it would let the port get all the way up to 105ºC before stopping charging, throwing a charge fault, and setting a P0E5F code. Now it derates when it gets to 80ºC so it doesn't get hotter than that.

Actually I think I might go pull the 12v battery again. I'd got the door module update a second time a week or two ago, and 4.3.6.
BTW when i pulled the 12v I could still open the door with no issues. I tried for nearly 20 minutes opening the door a couple times. The screens never came on but the door kept opening with no problem. Wonder just how much capacitor is in this car lol.
That's because the door latch modules have internal battery backups to still operate with no external 12V present.

My garage never gets above 80 when I charge because it’s always in the evening

Usually it much cooler, it derates every time now

But since I’ve already derated the EVSE hard to know when it is fixed
If your garage temp is only 80ºF and you're derating, then you almost certainly have a bad charge port or J1772 handle (bad connection). You shouldn't see any derates unless you're charging in temps above 86ºF or so.

@Mach-Lee I updated my reply above with the 3 DTC's that showed up. However when I first connect Forscan I get a bunch more in it's start up log.

I dont believe it’s the 1772 because it never gets hot, I measure it with in infrared device and I feel it



Seems you are 100% certain it’s a bad port and not from an OTA

And to add- if no code is thrown how do they know to change the port

Have you checked your Ford EVSE to confirm that it is working properly? It could be your problem is your EVSE, and not the issue others are reporting here. My Ford EVSE overheats rather easily, causing the same problem you are describing.
No problems or changes, zero errors and no failed charging sessions I just observed slower charging after the two most recent OTA updates. I’m pretty consistent when I plug in at night and unplug in AM. All L2 home charging in past 90 days.

Have you looked at the LEDs on the EVSE when the charging slows down? If they are blinking yellow or red, the EVSE is overheating. That is normal for the Ford EVSE in warm/hot ambient temperatures. Mine works fine in the winter, and slows down in the summer unless I keep it cool some way.

Those are all normal/typical codes except for the APIM B108E:4B overheating display. Which may even be expected due to the crazy temps you get there when parked in the sun.

Keep in mind the pin temps are a lot hotter than the external temps, and they cool off within seconds after unplugging. I don't think you can get an accurate pin temp with an IR thermometer.

And to add- if no code is thrown how do they know to change the port
That is a valid concern I hope they address somehow, otherwise some people with bad ports will be stuck with derated charging forever.

Working normal as I replied earlier zero lights, messages or reported errors. Just noticeably slower charging since recent updates. It’s been over 100 in Texas for a while and overnight in the upper 70s for several months and before the last few updates it was very constant. Never gave it much though until last week when it didn’t finish by 7:30 and then I reviewed and saw longer sessions. Maybe not related to the issues being discussed here and it’s still working so I have no complaints just thought it might be another data point for discussion.

I know for sure it was happening back on May 1st.

And it honestly wasn't that hot.

Hello Everyone!
I am having the same issue, but my Ford Dealer REFUSES to do anything. They keep telling me that they run diagnostics on my car and there nothing is wrong with it. What's kind of insane is that instead of listening to me, they just keep telling me that I don't have a Level 2 charger in my garage.

Joy of being a female talking to a car dealership.

Anyone know of a way I can make them fix my car? I've explained the issue to them numerous times. I have taken a picture of the yellow solid light that will go on my Ford EVSE. Ive shown them this thread and asked them to check the temperature sensor and the charge port. I've explained that it use to charge just fine and for the last 2-3 months or so it hasn't.

I've even had a friend with a Tesla plug into my EVSE, show them what they were able to pull from my charger without any issue. The Ford Dealership either can't be bothered with me or thinks I'm wrong and plugging into a Level 1.

Is there anyway to get the corporate level involved? I'm assuming there hasn't been any sort of recall notice or memo that I can point my Ford Dealership to?

Not yet, your best bet is to go to another dealer if you can. Unfortunately some dealerships just can't be bothered with EV's

As for those asking if it was always was like this, I have had this car 2.5 years. The reason I purchased a smart EVSE was to monitor my energy consumption. I would have definitely noticed this from day 1 if it was like this. Ambient temperatures have nothing to do with it. Like i have said before, I STRONGLY believe that the temp sensor was already faulty from factory or degraded quickly over time and only started throttling after the DCFC update. This was NOT happening anyyime before the DCFC update.

If you have an Amber light on the Ford EVSE, it indicates a problem with the EVSE, not the car. That isn’t to say that car doesn’t also have an issue, but you need to get a functioning EVSE to see if the car will charge at the proper rate.

OK but the Ford EVSE will definitely overheat when it is 100 F ambient temp. And it won't cause any error messages. It will just charge more slowly, exactly like you are experiencing.

Hi! I thought a solid amber light on the EVSE meant that the car wasn't accepting all available / the car is limiting itself. And a blinking yellow light meant there was something wrong with the EVSE?

My friends Tesla charged and pulled ~7kWh just fine. (40 Amp Switch)

Yes, replacing the charge port is likely going to be the fix for the derate issue.
I wouldn’t go that far. I had my charge port replaced and it didn’t solve anything. ?‍♂
