L2 charging speed recently dropped 33%

[kennethjk]

I am in NY and car is always garaged when charging, temp outside was 80 yesterday during the day and much lower at night and charged last night starting at 9 pm.


My juicebox unit temperature was not an issue in my case. I really need another 40 amp unit to see if same thing is happening.

We’re all stuck with it currently

 

[SpeedRacer72]

In Northern California it has been in the upper 90's, and my charging has been cycling from 8kw to 6kw like everyone else.
We recently had a spat of cool weather and the highs were in the 80's.
My charging did not cycle on that day and look at the difference in time for adding an 83% charge.
2 days apart. 1 hour longer to charge in 90° weather

Both of these charges were with the same charger.

@Ford Motor Company should be embarrassed and ashamed
The #1 problem with EV's is recharging, instead of making changes to speed up recharging, they are slowing it down. Why?

They slow it down so you do not overheat the charging port and catch your car on fire. The problem is there is a temp detector in the charging port which is giving wrong readings (too high). Ford changed my charging port and I no longer have this problem. Take it to your dealer and have them look at the temperature readings for the charger port. One or more will be way too high even when not charging

I talked to my dealer about this issue two days ago and was told they have received no direction from Ford to date about this issue. Nice to see some are getting their defective temp sensor fixed not here yet thou.

Back in July I took my car to the Ford Dealer for this charging issue, they found the error codes in the pic below.
The Ford procedure says to clear the error codes and try charging and see if the error codes come back. They have a 6kw charger at the dealer, they plugged it in, charged it up and no error codes.
I told them it needs to be plugged into a 10.5KW charger to see the problem. They do not have a charger that size. So they could not replicate the issue.
As I have stated before, the dealerships are woefully unprepared to handle any type of repairs on this car.
The worst part is the service advisor told me they had several other MME's in their shop for the same charging issue.

But to me the bigger issue is that if the charging issue is occurring because of a high charge port temp, real or simply a sensor issue, why doesn't the car give you a warning that there is a problem.
If it is, as you say, a risk of the car catching on fire, shouldn't the car, at a minimum, throw a warning and let you know there is a problem.
Not just continue with no warning as to what is going on until it actually catches on fire.

The error messages below were not throwing any warnings on the screen either.

To me, lack of communication from the car and from Ford is a major problem, and there are a lot of people on this forum that are experiencing the same charging issue and not a peep from @Ford Motor Company

That is why I say Ford should be ashamed and embarrassed.

Brought my car in today for this problem and this is the response from Ford to the tech working on my car.


no Satisfaction on this and they are totally clueless that there is a problem here.

The letter implies that the software changes intended to protect the DC charging process from overheating could cause this AC charging change without quite explaining whether that is intentional or quantitatively.

It can't really have anything to do with battery heating and health, since DC charging involves much, much, more current to the battery than is present here. The letter is silent about heating of the on-board AC charger.

Check out this thread.

TLDR: SOBDM software was changed to start throttling the charge rate when the charge port AC sensor hits 75C. Prior to that, there was no throttling. Instead, charging stopped and stored a DTC if the temp hit 105C.

The SSM allows the dealer to replace the charge port if one of those DTCs is stored, but, thanks to the software change, it will never get hot enough to raise a DTC. ?

Excellent summary. This should be on the original post now.

Sounds like that letter is just turning their backs on it and playing silly bastard as they know they handicapped the car again with software. Have a hunch they had problems with over heating and this is the answer lower the charging below what it was specified it could do when we bought the vehicle. The car is so smart it is lowering the charge rate because it can not handle anything more without overheating. Shear genius and working as designed ? This is normal operation not for the first 2 years but it is now.

Letter sounds like a too bad for you (all us). They may not be tracking it but they definitely have reports and know exactly what the software was to do and is doing. Again an opaque but obvious shitty move from Ford.

I guess we keep holding our breath that some integrity will appear.

Shenanigans, you say! May be better than saying shitty?

Time to get my cigar torch lighter and put near the charge port. Maybe that will set off a DTC

when My option plan is up and I dump the car I wonder if Ford really cares why I won’t get another one.

this and the HVBJB are really one and the same to me.

I’ll also add, that my wife’s car WAS stopping charging. Back around Christmas 2022. It had stored codes when we took it in. She got a new charge port and SOBDM in February and as soon as Spring hit, and it was above 32 degrees in the garage, we noted the throttling. So we got a new charge port, and we still have throttling. So even a new charge port doesn’t prevent the throttling.

Just derate it to ensure the code is not sent so the problem need not be fixed or temporary and they are they still looking into it for a fix?

From the SSM 51866 - Overheated Charge Port, DTC P0E5F Stored In The SOBDM thread

NOTE: As of this writing, P0E5F (105ºC) will effectively not be set with the current SOBDM software, which limits charge port temp to 80ºC through a derating strategy. 105ºC will never be reached. A vehicle with a defective charge port will only experience a reduced charge rate, with no codes set (silent failure). Therefore I don't see this SSM being very helpful unless you are somehow still on the old SOBDM software that allowed overheat all the way to the 105ºC cutoff threshold.

Went through all my old logs of codes and the P0E5F 105C code was never sent. I must be between the 105 and the 80C? So never hot enough to cause the code/problem but derated anyway. It is the lack of transparency that wears on you. Tell us like it is so we understand their position and can deal with it but no we keep guessing. I wish they would report the problem along with the plan they have currently adopted and are working towards. I would accept bug reported working on a fix or the software is the fix as then we understand and stop guessing. Sneaking in the software with no notice and letting us guess was questionable when all was working great here for 2 years with no fires.

Pins shiny clean and still straight as arrows here but still throttled. Hey Ford nothing looks melted or like it has overheated here just handicapped. Too conservative like the DC charging curve? My dealer still says he is waiting for the next steps from Ford. No guarantee or warm fuzzy feeling on the third HVJB they just install what Ford sends.

Several have reported that charge port replacement did fix it. It’s possible that your replacement is out of spec. It would interesting to see what your port temp sensor is reading during throttling.
