Hight Voltage Battery overheating during charging on L2 after OTA

[Light_Parry]

Just to add to the list of affected vehicles, my 2022 GT seems to have similar issues as the OP. I use a low powered L2 charger at home. I have been noticing in the last few weeks (likely after 6.6.0 update) that my MME always keeps charging, sometimes with fans spinning loudly, and keeping the garage warm.

Should I wait for a new OTA fix, or should I schedule an appointment?

It will not

Reinstalling 6.6 (or the twin CSP) will not fix it?

Hoping that the software rework fixes the slow L2 charging some have been experiencing for months after receiving the melting and burning port fix.

If you do not regularly charge on L1 or low power L2, the likelihood this impacts you is infinitesimal small

Would not every charger see this phenomena if the car is effected? I understand the problem is it heats the batteries up before attempting to charge them? Why would it not just ensure they are above 0C and let the charging heat them up? This is a waste of grid power on any charger and should be noticeable? The power-up 6.6 or CSP cord stuck sees my charging at too hot and derates it on the flip side it see these as too cold and tries to heat them. Definite something wrong with the new transfer function on some.

Give them a call and a heads up you have a problem to start and see what they say ?‍ If you have read all these pages it should of given you a good feel for what bringing it in right now would accomplish. I am not sure as I do not have this problem thank goodness. I guess if I did I would be looking for the closes DCFC. If you are going to keep it try not to let the big battery get too low or die while waiting for the problem to be addressed. Charge, drive and maintain itself is not to much to ask of AI. Hey Alexa!

Do we know if Ford has released a fix for this yet? I am bringing the car in to the dealer but do not want to waste my time and the dealers.

A quick update, the dealership is clueless. The tech was telling me this completely normal and the car needs to be at 30c to charge.
told him won’t take the car is this is not resolved. Gave him as much info from this thread to tell me they will contact Ford for assistance.
Told him to charge the car over 70% to keep room to test my L1 charger. When I mentioned the forum the guy got frustrated and told me I know what I’m doing.
gonna be fun dealing with this

Ugh, the worst is when they pretend they actually knows. What’s next? “Oh mate! I hear where ya coming from, but them HVBJB issues are fairy tales. Ye just have to drive ‘em car normal and nothing bad will ever happens to it”.

It is truly frustrating to see that Ford is still not pushing out a fix for an issue like this. I am not even going to bother taking mine to dealership anytime soon.

Having the same issue. On my 2022 GT PE, noticed it caps/slows the charging speed as well.

I would walk into the garage on my L2 6/kwh charging and it the car has fans on and is loud. Check the app and it says avg charge rate was 2 or 3 kWh.

one time I let it charge with no % restriction 2-3weeks ago, got in the car and it said I had 330 miles range on my GT PE(mind you my normal 100% is about 265-270) I drove to work(20 miles) and the car still showed 98%

Been weird… this all started after I got the updates and the dealer had my car for the hvbjb recall
This is when my mileage showed 330 miles..

These are all on my same home charger… as you can tell the charge rate keeps changing.
Normally it’s about 6-7% charge an hour. When it acts weird it’s like 3-4%.

charged for 11 hours for 47%

My home power isn’t dirty and haven’t had this issue until just a few weeks back.

Have them check for a PCM update today and apply it if available. I’m not sure if it’s available for your car yet.

Oh that was the exact reaction when we went in for our HVBJB replacement. He was telling me I don’t see the recall on the car. Had to basically show him all the errors, after that they fixed it within 3 days so can’t complain

Just seeing this thread now. Interestingly, my electric bill has gone up significantly in the past two months. We added a Lightning to our stable but it really shouldn't be a 50% increase in kwh usage.

I looked at Mach E charge logs versus kwh usage on the utility website and they don't seem to match up. BUT it looks like idle times for power delivery are spiking. So we think the Mach E is drawing more power while plugged in, right? (Sorry didn't read the wholeee thread).

That is exactly what I have been experiencing, too.

Preface:
1) We supply electricity to our EVs directly via our solar panels [AC coupled, bimodal {back-up} PV system], 98% of time, L1.
2) L2 EVSE used occasionally to be certain it still works and in winter when MME is fully charged and when we condition once/week, normally.
3) We are bottom of the barrel when it comes to OTAs, etc. There is a bit of an advantage here. We are better prepared for the many faults introduced by the never ending OTAs, thanks to this forum.

The question is: is it 6.6 or 6.2 after 6.6 causing this current misery?
We are not experiencing the above discussed torture.

We have 6.6 but pretty certain not 6.2
We have "dumb" EVSEs: Clipper Creek L2 and a GM (Bolt) supplied L1 (5+ years each), both of which perform flawlessly. MME is garaged (unheated).
We had 22P31B, 23B50, 23P08B, 23S56B/C installed/performed last week. L1 and L2 used both before and after.

Since we are experiencing none of the above nonsense, is it possible 6.2 is the culprit and has been stopped (since we are the last on the list)? Process of elimination seems to indicate this. Or?
Luck is not in the stars here, so it can be eliminated.

footnote: since we use electricity supplied by our solar, we cannot offer any help w/ utility bills.
However, we have monitoring ability w/ our system and have not noticed anything out of the ordinary.

Update power up 6.6 of CSP cord stuck is causing the issue. It has gone rogue and wants to heat the batteries up to something ridiculous before it starts charging. L1 does not have the power to heat them up so they are actually losing battery soc heating them up trying to charge it. This is the result of a heat transfer function software released that has caused numerous L1 and L2 issues. Hoping at least the ports are not burning and melting anymore. Just the HVB now.

So then that means everyone is having this issue? If it’s 6.6 then I believe most everyone here has that update. Believe my latest was 6.7.

If this is really true, then of all the issues with this car, this one pisses me off the most. Why? Because it is nearly tripling my electric bill. It’s insane. A software bug that is racking up kWh on the electric bill…I’d rather pay a subscription for heated seats because at least I know what I’m getting!

Ford needs to fucking fix this.

Not everyone only a lucky few. I do not have it I have the issue that it slows my L2 charging down to a crawl after the CSP/power up "fix".
