Is it or is it that some peoples EVSE will not vary (lower) the charge amperage automatically and therefore charging stops? Once it is lowered manually it will charge again. Think code P0E5F may be present will need to look one day. There is this Link. My Grizzl-e extreme has not stopped just the speed of charging (amperage) has decreased.
That's not how it works, most EVSEs do not lower the charging amperage automatically. The car does that, not the EVSE. Exceptions are if your smart EVSE has a slider, you can manually adjust it (still fixed to your setting), or in rare cases if you have solar controlling the EVSE output.

EVSE says "I have 40A max available"
Car says "I'm here, turn on power" and the car decides how much to draw from 0-40A.
When charging is done car says "Turn off power" and that's what happens.

With a standard dumb EVSE, it advertises the "40A available" the whole time, doesn't change. The car's on-board charger decides how much it wants to use and varies the draw if necessary. It just needs to stay under the limit the EVSE gives it.

Understand it is the car asking for 48 amps no 32 amps no 48 amps and so on. Every EVSE work the same and none fault set at 48 amp if 32 amp is requested? Why are they faulting at 48 amp and when lowered to 32 are charging while some are jumping up and down between 48 and 32 like a jack rabbit?

I’ve done a ton of testing and logging what happens.
I DO have the issue where the car lowers charge speed up and down once a charge has actually gotten going. It seems to toggle between roughly 24A and 32A.
If it hasn’t been charging recently trying to charge at 40A will error after about 5 minutes and stop the charge. 32A consistently works.
Sometimes if I keep trying over and over again a 40A charger will eventually function but only at 24/32A.
The Ford BEV team reached out and indicated that the dealership was prepped with the correct data to test and fix this.

No, the car doesn’t ask for 48 amps from the EVSE. It is told the max and has to abide by it. It’s not a two-way communication. That’s how DC charging works, not AC charging.

And let’s be clear, we’re talking about the “plugged in not charging” message in this topic, not reduced charging rate. I think they are separate issues, and this one might be caused by a minor glitch in the pilot signal from the EVSE.

Unfortunately that plugged in not charging message is as clear as a check engine light. The two may definitely be related as it is in my case so we cannot unfortunately discount the possibility that they are related. I couldn't get the car to charge unless i lowered the max current to 40. Now that the car finally started charging i get the sawtooth pattern. They definitely can be related.

Mine was acting up again. Turned ignition off and plugged in. It's before my scheduled charge time so it shouldn't charge yet. EVSE clicks into J1772 State C, but then it didn't drop down to State B after 5 seconds like normal. Instead it stayed in State C (power on) without drawing power, which is abnormal. Charge port ring was solid blue. This state continued until the car noticed my phone nearby and activated the welcome lighting, then it snapped out of it and finally went back to State B.

This typifies the pattern of getting "stuck" without drawing power, but then when the car is disturbed or woken up by something, it snaps out of it and returns to normal. So if charging stops, try to do something to wake up the car like opening a door, refreshing FordPass status, or sending a remote lock command. Or follow the advice in the recent SSM and unplug the car and try again.

The car subsequently charged at 40A for several hours without any interruptions or derates.

Yep, I had this same issue. It only impacts level 2 charging, using a level 3 charger won’t recreate the issue. The dealership recently replaced my charging port and it resolved the issue. Right before they replaced it, it had gotten so bad that even 30A would trigger it to stop charging on occasion…thankfully it’s no longer an issue.

I just got my car back from the dealership and it was in fact the charge port that needed replaced. The work was done under warranty. I have been happily charging at 40A for an hour now without issue. I HIGHLY recommend opening a ticket with the BEV team at Ford as the smoothed over the process quite a bit with the dealer.

My dealer has now had our car for a week and still thinks a software patch may fix it in the morning. I suggested the wire harness/port but it looks like I will have to be calling BEV support via 800-392-3673 in the morning. Good to see this is a fix.

The BEV team was incredibly helpful for me. They confirmed that my vin was on a list of cars the they know the charge port is an issue for. They worked closely with the dealer tech to handle it for me. They would be the ones to tell the dealer if this is a hardware issue or a software one.

Did your car have the yo-yo charging? Mine always charges so it may different than yours . It just goes from 40-32-40-32 constantly, never shuts down and no alerts whatsoever

Yes it did yo-yo charge. If 40A or higher it pretty consistently wouldn’t charge. 32A and higher it would yo-yo down to something like 24A. Replacing the charge port fixed that too.

I'm seeing the same behavior where it goes into State C and never exits, even when I do the steps you outlined, it's a new 2023 GT, I've never had a BEV behave in this manner, Mine gets stuck in State C indefinitely. Ford blames my Clipper Creek HC-40, but I know better my F150 doesn't do that on the same exact hardware, I took my Ford Branded EVSE from my F150 Lighting and plugged it into a wall outlet, it does the same behaviour where the charge completion time moves forward, as that time approaches it moves again, and stays at 89% when the target charge level is 90%

Where do you see the J1772 states? I don't recall seeing this in CarScanner.
