L2 charging speed recently dropped 33%

[Shayne]

I have the report from the dealer picked up the car. Apparently the error was thrown multiple times over the past few weeks in the sobdm module (on board charging module) So for all of you who are having issues you can point your dealer there. Its the p0E5F error https://www.macheforum.com/site/threads/p0e5f-error-in-sobdm.26060/

This seems like its going to eventually affect all cars. I didn't expect it to fall under the battery warranty because you can't really consider as part of the drivetrain. Example: a gas tank or fuel pump wouldn't be covered under the drivetrain warranty.

You mentioned that charging speed has slowed down but not that it cuts out and stops charging as link indicated; correct? Has that changed? What does your service say the cause/fix is? Anything at this stage?

Right now it seems a software issue discovered a hardware issue and we will have to wait and see.

Both together sound like an issue rounding it up to a few issues . Nothing melted here that I can see, just got updated.

May not have honored a schedule to begin with but always L2 charged like a champ just too soon and too much. Me I do not put lots of miles on it but you would think after 2.5 years of no problems it was tested and OK? Mine is making it to requested % just takes hours longer. Fan and pump very rarely come on up here. The saw tooth (pulsing the electronics) may not be ideal? Wondering if slowing down will lead to cutting out? Possible some chargers if they can not supply their set amperage just stop? My grizzle seems to be able to vary it on cars request. No longer steady 40 amp

Update on our 2022 MME L2 charging post 4.2.6. I switched AC coupler temperature reading in car scanner app to the other one labeled the same. After 30 minutes of charging on a 40A Grizzl E, coupler temperature reading was 165F and there was a humming sound coming from the car. Charge rate was 8.99 to 9.9 kW and AC charging current was back and forth from 39A to 40A; charger output amps was 24.8A DC to 25.0A DC. I switched apps to FP and FP was showing a 6kW charge rate while the car was showing 8.99kW charge rate (I believe the car over the FP app lol). I will check coupler temperature at the 1 hour point. Garage ambient temperature during this part of the charge was 85F.

It cuts out after a few seconds if i leave it at 48 amps. I used to charge at 48 but now have to lower it to 40 for it charge. They suspect that the thermal sensor on the port harness is defective and throwing codes so they are replacing the harness.

I look forward to taking the time to make these temp. measurements in my car, maybe this weekend. This thread really shows the power of our cooperation in chasing down things like this. I'm glad I ponied up (sorry) for Ford Protect.

If it’s happening to so many people after an update it would be surprising that it’s the harness.

my car does not make any of the cooling sounds while charging that it used to make. Could it be hardware, I suppose yes, but most likely the 4.2.6 update that mine actually did not upload. See attached picture

also is a picture when charging at 40 amp from last night. I changed to 32 amp this morning, other than a blip when I started the car while charging its holding at a steady 32 amp.

it’s got to be software and hopefully doesn’t blow any hardware. Wild guess on my part of course.

car charges to desired %, just longer to charge but crickets from Ford, my service manager knows nothing and they are pretty much on top of things. hopefully something doesn’t blow out on the road, as someone mentioned earlier.

I have not had the problem recur. It only happened when the car was in the driveway, in the sun and very hot. In my garage it seems to be fine. Full 48 Amps is delivered without issues.

Mine was in garage at night. Wasn’t that warm. I no longer hear all the cooling pumps and noise that goes with it.

car going in on 7/24, will see what they say

30 pulses in 4.7 hours up and down every 9 - 10 minutes. Not sure if the hardware likes that? What charger is feeding it? Could you lower it to 40 amp (not 32) and see what the graph says. I have a dumb charger as I thought you just plug it in and it works . It was 10C and mine took hours longer to charge? No fans no pumps is normal. Not a heat issue here.

I have a Juicebox 40 amp, the up and down was at 40, when I lowered it to 32 it stopped jumping up and down, will try again tonight

this seems to be what some others are seeing , some with Juicebox and some with other manufacturers

I have to charge up to 100% tonight for a trip and will do it at 32 amp and see if any issues.

Meant this

Could you try 40 amps not 32 amps and see what happens. People have tried 32 amps before.

The other graph on the right is at 32

There was one blip in that one but it was when I started the car, other than that it stayed at a steady 32

Understand the one I highlighted going up and down is your 48 amp and then you tried 32 amp to the right for a bit and works ?.

Edit: My bad yours if 40 amps so that is what it is doing at a 40 amp setting

Guess I am not making myself clear or I don’t understand

The section of the graph on the left is at 40 amp since my unit is only a 40 amp unit

The section of the graph on the right is at 32 amp after I lowered the amperage on the unit

My bad and edited it proir to your post but you are quick. Thought it was 48 amp so same up and down set at 40 amp. That is what I see in FP but not as graphical takes hours longer to charge.

I am retired and have nothing else to do , LOL, plus at the Drs right now waiting for my wife to finish up and see if her Achilles is still attached, ouch

This seems (not her Achilles) to have started after an update- just wish every time I get an OTA I don’t have to fear something else breaking

most of the “breakage “ has been minor. I consider this one a bit worse because as you said the up and down can’t be good for the hardware
