I'm not even hearing crickets anymore...

I would recommend using the Ford Mobile Charger and not doing any of the rest of the stuff that you did.Back to the original thread topic - YES, ever since 6.5 loaded on Dec 15th I have had problems and NO, Ford didn't acknowledge there was a problem. they told me to use a Ford charger and see if the problem goes away - well it didn't.
That said, I have the data that shows how bad this problem really is - 67% of the 7.1 kWh was wasted either cooling or heating the HVB. See the attached Excel File. One other side note - Is 157 deg F hot for the AC connector, and could that be the problem? (bad sensor?)
Forgot to also point out that the charge input kWh per charge was no more 2X than it should have been - based on hours X kWh.
During the 2 1/2 hrs I spent tracking this charging event (with the Ford Travel Charger), less than 20% of the time was spent just charging the battery. One could say that 88 minutes to heat / condition the battery was within reason, but it was 50 deg F, hardly cold enough to require that much heating.
I first noted the problem when my charge profile went from this

To this,

What the heck was going on, I reduced the charge from 4 kWh to 1.4 kWh and guess what? The battery SOC went from 70% down to 68% overnight!!!
I believe the dips in the charge profile are when it switched between cooling or heating.
I went outside to look at the car during the next charge; the grill vents were open and the AC Compressor was running. The next day, as soon as I plugged in the charger I heard liquid running through the battery, then the heater kicked on.
Here are a few scans that I used to construct the Excel file. This is when it was charging normally, although the inlet temp (upper left) is dropping, the HVB temp stays at 98.6 for until the AC compressor kicks on:

All of the input NRG was going into charging and the grill vents were closed.
Here is what it looks like when the inlet heater is drawing over 5.3 kWh (no wonder I lost SOC with only 1.4 kWh) notice the bottom right charge - this is how much is going into the HVB.

Here is the scan Pic for the AC Compressor Drawn ot as bad as the heater but it would suck up every amp (6) when I had the charger set at 1.4 kWh:

The big question is, what now. I have 6.6.0 but that didn't help. I have the letter for CS 23B50, but Ford said that update will not change with problem, it only addresses the charge cable getting stuck in the car. I asked if there was an OTA coming that would fix it (like 6.7.0), but they said my car was up to date!!! How can that be when some MME are already running 6.13?
So,
Do I send it to the shop, and ask them to do what?
Do I just crank up my charger to 48 kWh and hopefully cut down the charging time and wasted NRG? Then hope the next OTA comes soon and fixes the problem?
Do I drive 50 miles to the closest DCFC and give that a try (one of the benefits of living in South Louisiana)?
If you have an idea that worked for you, please let me know.
You have the Level 2 battery overheating problem. Battery shouldn't be heating past 50ÂşF and yours is 98ÂşF. Read below topic carefully.I would just use the Ford charger, but the OpenEVSE can be set anywhere from 6 to 48 amps and I like to charge at the slowest rate the car requires (17 amps or 4 kWh) to reduce stressing the batteries. My OpenEVSE set at 40 amps will charge faster than the Ford and actually wastes less NRG heating and cooling. In addition, I would like to leave the Ford travel charger for just travel. Lastly, there is still a major problem with the car charging system that has taken my electric cost from 5 to 9 cents per mile and switching chargers doesn't fix that problem.
But you are correct, I could just use the Ford Charger.
Many of the updates have been paused. Are you in the Early Access Program? Most folks who have continued to receive 6.x updates are in the EAP.My 23 has been stuck on 6.2.1 equivalent since Dec 5th. I was really hoping to get the update which resolves the occasional trunk opening bug by now. Did updates get paused again?
I see that my RGTM has a pending update in FDRS, but nothing's being pushed to me over OTA :|.
Did you compare the Power Up number with the list in the poll?Not sure if this is part of the 6.x version of updates but I received the update that adds AM radio today on my '23. Last update before this one was 6.13.
Sounds like 23-PU0907-RAD-ON.Not sure if this is part of the 6.x version of updates but I received the update that adds AM radio today on my '23. Last update before this one was 6.13.
Isn’t that 23-AM0907-RADIO-ON?Sounds like 23-PU0907-RAD-ON.
