L2 charging speed recently dropped 33%

[kdryden99]

Mine is out of warranty. Thankfully I bought the extended service plan.

One thing I am curious about is, is the temp sensor the same model and version in the new harness as the one that came in the car? This might add some clarity to the situation but unless someone can get their hands on both, i don't think we'll find out.

It’s out of our hands sadly. As it’s a charge ‘curve’.
The good thing is, is that Ford‘s aware of it the bad thing is is that they suck ass with getting updates out

And tell us, nothing

Its more than a charge curve. Many of us have found the charge port temp detectors are faulty giving high temp readings in error. Why are there so many failures of the temp detectors? Should this be a recall item?

New owner here and have been dealing with Ford home charger running hot and cycling in and out of fault (amber light on momentarily, blue light pulsing). This is the charger rebooting. Looks a lot like the graphs I see on this post. When the amber light comes on the charging stops until it comes out of fault and is rebooted, charges again and then goes back int fault. Nailed it down to the outlet in the wall NOT being a "high enough" grade industrial device. It's causing heat to build up at the outlet and causing the charging brick to run hot as well. It wasn't hot, hot but it was pretty warm. I figured this out by placing my small shop blower in front of/below the brick and outlet. It cooled down quickly, it stabilized and started charging steadily and much faster at 6kW. Heat buildup will also reduce charge rate. Cool the outlet and charging brick with a blower or fan to see if that stabilizes your charge session and see if this might be the issue. These outlets are operating at the high-end level of their design and the connection at the back of the outlet must be TIGHT!

My current "industrial" outlet specs. state that it can only be torqued down to 25 lbs-in. There are plenty of posts and you tube videos out there that state you need to torque the lugs on the back of the outlet to 75 lbs-in. I checked the torques specs on the Hubbell outlet and find that this outlet (NEMA 14-50 9450A) can be torqued to that spec. My new Hubbell outlet will be here today, and I'll see if that corrects my charging issue after I install it and achieve the 75 lbs-in spec.

Moral of the story here is that all "industrial" outlets are NOT the same. Check the torque specs. on the outlet brand that is installed in your wall by looking the brand and model up and reading the installation instructions, and if the torque specification is not 75 lbs-in, then change it and achieve those specs.

I have the 9450A Hubble torqued correctly and the yo yo is happening

I don’t believe it’s my outlet

It’s fords software that’s a problem

Yeah, I think we've established it's either a bad charge port or bad software causing the slow charge rate issue.

Amber light on the mobile charger is a separate issue.

Went back through my FordPass charge logs to plot my charge rate and my rate dropped to 25% of the prior baseline rate on my apartment's L2 charger starting July 20. This aligns with when I got the 23-PU0314-DCM-LAT update when I look at the message center in the app. Do folks in this thread see their charge rate impact align with the update timing? Weather is perfect here in the Bay Area and I've got no errors or warning lights.

That's the door control module update, seems unlikely that would affect charging? Unless it's some sort of reset effect that rebooted the charger module?

Yeah I looked through the thread about that specific update and it seemed innocuous enough. Looks like it started rolling out around the same time as this thread was created so makes me more suspicious but I'm not sure if Ford updates have any server side flags that turn on features later than when the software was installed (like how Google does for their apps).

At some point the car is too old for them to bother updating anyway. I bet an 8 year old car won't be getting many updates. You will have to upgrade to MME 2.0 to get future patches.

I do not need updates. What I need is one update that makes all things work as they should and then I do not need updates ever again. Do not need fluff software add ons not even BC just drive, charge and maintain (and my tunes connected). If I got my AC charging back and remote departure scheduling back I would be happy and would not need anything else at this stage. Things have gotten better and all else is working OK. Been a long time to get the basics ironed out for me. I started with things that are required for an EV that just did not work, they got fixed and now I am left with things that did work that no longer do. Every time it is for months.

Please ford get the basics working and to the standard that we know you can. So simple to ensure priority is given to the basics working but nope off on a tangent. People do not care what makes an EV work until they don't.

?‍ ?‍ ?‍ ?‍ ?‍ Not the charger or outlet it was charging for 2.5 years at a constant 40 amp and now charges like crap after ford issued an update. It is the car and starting to point fingers at chargers and outlets is a Ford thing not a new guy thing. How many months do people think we will need to put up with this for? Ford has not got back to my dealer with the next steps yet 2 weeks and counting.

I do not need updates.

I agree. However, I did appreciate the update that added 3 kWh to the available capacity. I would take another one that opens up more of the battery.

I miss my big tiles. That update was a bummer. I would like my big tiles back.

And loading the wrong profile is getting super annoying... so fixing that would be awesome.

Well said.

It's probably something stupid...

Adding 3 KW to useable battery increased range by 91-88/88KWh or 3.4%. What would be nice is to be able to DCFC it over 80%. Reasonably being able to charge to 90% would add 10% (3 times more range) and to charge it to 100% would add 20% more range than we have. The increase in useable battery gave us 80% of 3.4% or 2.7% more range. Nothing to write home about or get too excited about in my opinion and would have preferred the 10 to 20% and a half decent DCFC curve. That I will live with just limits travel when cold and I do not DCFC/travel too much.

The new UI I have no problems with was not required but not a problem here. I like it.

I do not have the profile problem but understand. The simple stuff if it just does not work can cause a bad experience. Especially when it sometimes does so it keeps you trying and has no quick work around. Lots of different problems that not everyone has is what I have noticed.
