L2 charging speed recently dropped 33%

[Murse-In-Airy]

2 cars one does it one doesn't on the same power and charger has to be the charger . Would your service even confirm it is not charging to spec or no diagnostic/comment? If something on the vehicle is overheating to de-rate charging it would be nice if it was at least acknowledged and better yet addressed. All we have to date is de-rate it for our possible safety, with no further DTC codes and they are not too concerned about which owners that effects or for how long.

Someone mentioned here we can have hope that 6.1 brings something (did it do something for hers?). Thought it was going to take a while to address but now thinking they may just not. ?‍ Reasons just keep stacking up.

Her car is an original 2021 job one. It did have DTC codes when it was failing to charge completely. Red ring lights. Had to be unplugged and replugged to restart the charge. My car is a 2021 job 2 GT-PE. So not the exact same car. We have 2 identical Grizzl-E chargers. So my trouble shooting included proving her car failed on both chargers while my car charged successfully on both chargers. So I proved, and the dealer listened, that it wasn’t a charger specific issue.
After her charge port was replaced they didn’t have a 40 amp charger to trial it on. They proved it would charge but not that it would charge at 40 amps. Only when I got it back home, did I note that it would no longer hold 40 amps.
As far as 6.1 changing anything I sincerely doubt it. However HER car was just back in for a new HVBJB and while it was in, the ring indicator lights (which hadn’t been working since the new charge port 7 months ago) began working again. So…. Maybe… just maybe… I need to run another test on her car this week.

So I noticed the throttling before on my Juicebox 40 last month. Now when I plug in, it will throw a charge fault error within a minute and not charge at all. I have to lower it to 32 or under 8kW and it will charge in a smooth constant rate with no throttling. Anyone else having this issue?

I was trying to charge my MME last night with a usual Amazing-E 16A that had been working flawless (except the first time because I didn't know how to use it) since May 2022. The charger added around 4,500 miles on both of my MMEs. Last night, it changed for 0.1kW, 0.3kW and 0.4kW before it stopped and blamed the MME all three times. I tried Ford L1 charger without any issue. Then I switched to another spare L2 charger and the car was charged to 90%. Oddly my Amazing-E worked two weeks ago without any issue. I just got version 6.1 on my MME couple days ago. The 6.1 might be very picky on which charger it wants to communicate with.

My 2022 MME got 6.1.0 on Thursday. Just started the first charge since it was installed. Initial charging rate was just over 9kw on a 40A Grizzl-E. So far I have not seen any throttling during charging at home on either of my MME's. Both average between 8.9kw and 9.1kw. I normally charge them both to 85%; charging the 2022 to 90% tonight for a day trip tomorrow. My 2023 has 5.1.1 installed and should be downloading 6.1.0 any day now based on previous history. I will post charge details once 2022 charge is done.

Here is an update on my first post 6.1.0 L2 charge. At the 1 hour 43 minute point of the charge, 15.4 kw had been added to the car (monitoring using OBDII reader and carscanner app). This averages out to 9.05kw per hour being added. Garage temperature has been around 64F during the charge. Just some info in case anyone is interested.

I received 6.1 yesterday. Followed by charging from 11% to 80% last night and can confirm that the 6.1 power-up did absolutely nothing here for my slow charging problem. Don't hold your breath there dude.

Actual times: Started 9 pm Oct. 14 and finish 5:51 AM (8.85 hours for 11 to 80%)

69% x 88 KW / 8.85 hr = 6.86 KW/hr

Bit better than before but with that average I say it is jumping around now.

Ambient temperature 6C (43F). Hours longer than it use to be. ?‍ Rolled my schedule to start an hour earlier now trying to split the difference. I want the 105C DTC code limit back.

Here are the final details on my first post 6.1.0 charge on my 2022 Select SR from last night:

Charge started at 4:03 pm; charge completed (to 90%) at 7:28 pm. Charged from 45% to 90%. Garage temperature averaged 66F during the charge.

.45 x 68kw / 3.41 hours = 8.97kw/hour charge rate
.45 x 70kw / 3.41 hours = 9.23kw/hour charge rate (if you want to include the additional 2kwh released)

These charge times and average charge rate is what I have seen on my 2022 since I got it in July 2022. I also see this average charge rate on my 2023 premium ER (same charger) since I got it in December 2022.

That looks good did you ever have an early build MME that got hit with an early June update that de-rated your charging?

I have not had an early build MME; first one was the 2022 that we bought July 2022. We have two MME's currently; no ICE vehicles. My 2022 was built in April 2022 and my 2023 was built in November 2022.

And were either hit with the de-rating software and your 9 KW/hr went below 7 KW/hr until software 6.1? As per title of this thread it is not for all Fords just us chosen few.

Neither of my MME's have been de-rated during L2 charging since I have took delivery of them. My 2023 is updated through OTA 5.1.1. I didn't start monitoring/checking L2 charging until this thread was started.

Only reason I posted my charge details was because @Monke said they noticed an issue just after their MME installed 6.1.0. My 2022 installed 6.1.0 this past Thursday so I thought I would post my first charge data following the update as a data point.

Now I understand that you never had the problem we are experiencing here you just saw no de-rating after 6.1 either. As noted above 6.1 had no impact on me either still crappy slow charging here. I am also thinking 6.1 has nothing to do with it.

Just checked. Can confirm I’m still being throttled for charging. Changed the Grizzl-E back to 40 amps. Plugged car in at 50°F. Initiated charge. OBDII/CarScanner confirmed drawing 40amps. 45 minutes later when I go back out, car is only drawing 30 amps. I watched for 10 minutes, jumped to 40 amps for almost a complete 2 minutes before falling to 30 amps again. Stayed at 30 amps for about 10 minutes then back to 40 amps for just under 2 minutes.
So her car appears to have received a bad charge port at the time of replacement. Can’t handle 40 amps continuously but with the software “fix” she’ll never see another DTC.

None of the 6.x updates so far will affect charging speed. It would have to be a powertrain software update before any changes are possible.

I didn’t suspect 6.x was going to affect this issue at all. My curiosity was more because the ring lights started working. So maybe the dealer had done some other update. If they did, it didn’t change this issue. Oh well. At least she can survive with 32 amp charging. Just had to charge outside the TOU window sometimes.

Yes. That happened to my Premium ER. I searched and saw some posts about bad connection on the EVSE and possible software patch. Then I did as what I said on the previous post. The previous charger only deliver roughly juice for 4,500 miles. It is hard to believe that it is broken already. It managed to deliver some kW three times until I gave up and switched to a new charger. The new charger has bright and shine metal connectors versus the old looking ones on the previous charger.

The annoying and very dangerous freeze screen has not showed up since 6.1. Last update in mid July made the freeze screen disappeared for a while before it came back almost daily right before my MME got the 6.1 version.
