Did anyone get the 23B50 update via OTA or going to the dealer is the only option? i am booked on November 27th for the update at the dealer and hoping to avoid the trip.
Updating your car through FDRS is another way to get 23B50 (6.6.0).

I charge my car mainly during the day on excess solar using my Emporia charger. I've posted graphs of my solid, non cycling charging stats and have been told because I only charge for a couple of hours that I will not get the up and down charge cycling that others get. Thought I would charge from the grid for an extended period of time to see if I get the cycling......

Last night after getting home from the airport I plugged in my car at around 11:00pm. I set the Emporia charger to start charging at midnight (12:00am) and the car is set to charge to 100%. The SOC when it started was 21%. By 6:30am this morning the car was at 90% and by 7:45am it was fully charged to 100%. At no time during the 6 1/2 hours from 21%-90% SOC did my charge drop below the average of 46.5A. I took screen shots of the Emporia graphs set to minutes. Each graph represents 40 minutes of time.

Not sure what you are saying with this one? You don't have the bug the rest of us are seeing?

From 21 to 90% is 69% in 6.5 hours or 0.69 x 88KW / 6.5hr is 9.3 KW/hr into the car. If you ball park efficiency at 85% that is 9.3/0.85 = 11 KW/hr or 11/0.24 KV = 46 amp. Pretty good sure does bet my 6.5 KW/hr. :(

His charge port is not overheating enough to cause his car to limit the charge rate. Mine takes two hours to get hot enough, yours much less. I think you need a new charge port, and mine probably needs to be cleaned.

This thread is about reduced charging speed and early on when this thread started I stated I had not seen this and was told by several members it was because maybe I only charge a few hours a day and I needed to charge for a longer period of time to see the issue. I rarely ever charge like I did last night as I would have normally just charged a couple of hours each day for the next few days on solar. I figured I would charge the car on grid power from a lower SOC up to 100% which would give me an enough time to see this issue. No matter what charge amperage I set my Emporia to, the car will charge at that and never fluctuate. I have the charge set to 48A and consistently get a solid average of 46.5A.

It likely depends on the condition of the charge port. On mine, using my emporia evse, it would start dropping after anywhere from 5-30 minutes depending on the ambient temperature. the lower the ambient temperature the longer it would stay at the full 11kwh speed before starting to bounce up and down. Ambient temps in the 30-40's will let it run almost 30 minutes at 11kw. Ambient temps in the 50-60's will run about 10-15 minutes at 11kw, Ambient temps 70 or higher will only charge at 11kw for about 5 minute.

I reached out to emporia and they even sent me a brand new replacement EVSE. It makes no difference.

I guess my charge port is in a worse condition then most.

Also for anyone considering an emporia evse, it looks like their more recent builds have cheapened out on the charge connector. It's now a smaller handle/connector and is plastic rather than metal. It has an open/slit on the top that might let water get in if you are charging in the rain.
I'm guessing it's a cost cutting move.

The car sat at the airport for 4 days with temps between 45˚-65˚. On the drive home last night the temperature averaged around 48˚. Charging at home my cars are in the garage and it's climate controlled to 68˚ in the winter, 80˚ in the summer so those were my temps when I was charging.

Do you know when Emporia changed to the different charge connector? My first Emporia charger I purchased about 1 1/2 years ago and the second about 3 months ago and they both have the same connector.

My first emporia was purchased in April. It had a February 2023 mfg date. The warranty replacement they sent last week had a October 2023 mfg date. So sometime between Feburary and October of this year they changed the charge handle.
Also the cable on the new unit is a lot stiffer. Harder to wrap around the wall mount charger.

Ok, so then very recently changed. The cable I had on the ChargePoint charger was very thing and flexible compare to Emporia's but it also got more warm than the Emporia cable does so not sure if they are using thicker gauge wire or not.

ChargePoint does use slightly smaller wires (9 AWG) than other brands (8 AWG) to increase cable flexibility. As a result, the cable and J1772 connection run a little warmer, and would be more likely to induce charge port overheating than other cable brands. It's still a great cable IMO, rated for 105ºC.

Look mine works you must be doing something wrong ;)

We are back to my service does nothing if not instructed and/or paid. Ford lowers the threshold to 80C and mine drops like a rock right off the bat like the temp reading is wrong and/or the senor is not responding. If anything could go wrong with driving, charging and maintain this vehicle mine will show me how that happens. I asked them to look at it and confirm but nothing for 6 month after the install just silence. They are aware of the problem just for now don't care. Not the best impression to do this to early adopters but either was the HVBJB. It is what it is.

How does any of the above explain why my juicebox does the yo-yo thing and my Autel doesn’t?

I am on my 3rd juicebox. Seems fine , could the JB plug be bad, like all the other people on this thread? Seems weird.

Grizzl-e extreme here and worked for 2.5 years fine until Ford installed software such it does not. Juice boxes, charge points, grrizzl-e's all of them are bad and the car with the new software is working as designed. If you call charging at your home like crap fine.

Obviously the car is the problem and was melting ports or causing burnt smells for so long they crapped out the charging speed to try to stop that. Ford is becoming known for fixing hardware defects with software by putting their vehicles in limp modes such that they no longer function as specified when we bought them. Been a great experience to see how Ford has the backs of their early adopters and does not only think about their own profit.

My GT-PE charges just fine. My job 1 premium AWD ER overheats and throttles. Maybe there was a small change in the part (supplier or gauge of some connecting wire) between the job ones and when they started making GT-PEs?
