L2 charging speed recently dropped 33%

[Shayne]

This really sucks, I can’t believe they still won't change the charge port. I'm certain that's the issue.

You got that right like the other defective hardware in this car it has been a great experience.

Did another charging experiment today after I "Cleaned" out the charge port with a bottle of compressed air.

It now charges at 11kw for 70-80% of the time, and then down to 8kw for the 20-30% of the time (tested on a 5 hr 50kwh total charge cycle). What I noticed is now the front vent is open and I can hear some kind of pump/fan noise. It's averaging around 10kwh charge rate over a 5 hour period.

Previously it would charge at 11kw for 20-30% of the time and 8kw for 70-80% of the time, the front vent would stay closed and there would be no pump/fan noise. Average is just above 8kwh charge rate over a 5 hour period.

Both tests were done in garage with ambient temps at 65 degrees.

Now my fordpass app doesn't show any charging info. No charge rate, energy added, amount of time on charger etc. I even tried to uninstall the fordpass app and reinstall. Still doesn't show that info.

I think cleaning mine I went from 6.3 KW to 6.5 KW charging. If it did not go below 8 KW I would be a happy camper. I have no fans no pumps but I think the de-rating is because of something that does not get liquid cooled. I have had no charging info, no logs also at times and then they come back ?‍ It has been hit and miss with charging info for me for some time. The info is not a problem for me the slow charge rate is. You can use

Percentage charged x 88 KW / time to charge = average charge rate.

or

50 KW/ 5 hours is an average of 10 KW/hr and pretty respectable.

My last charge was not 5 hours for 50 KW it was 8.5 hours to charge 55 KW. Feeling good that I am the slowest.

Repeated the same experiment today. Same car, Same charger. Only thing change was the ambient temp. Today it's 80 degrees.
The car charged at 11kwh for the first 18 minutes, then dropped to 8kwh. And started jumping up and down again. This time it spent 20-30% of the time at 11kw, and 70-80% at 8kwh. After 2 hours, it dropped even further. It started to drop between 8kwh and 5kwh spending about 70-80% at 8kwh and 20-30% of time at 5kwh. First hour it averaged 9kwh, second hour was 8kwh, 3rd-5th hour was 6kwh. Instead of 50kwh over 5 hours, today it charged 36kwh over 5 hours.

So 15 degree increase in ambient temp lowered the sustained charge rate significantly.

Up in NY my juicebox 40 jumps up and down after 40 minutes, car is always garaged and still happened in cooler weather.

car is in Florida now and was very warm and humid a couple of weeks ago, Autel 40 amp worked perfectly , 9.5 amp for hours straight

I don’t think outside temp has anything to do with it . Why Autel is better than Juicebox I have no idea

I also tested with the ford pro evse (the 80 amp unit that came with F150 lightning) and see the same exact result. Jumping up and down and higher ambient temps causes it to go lower.

Turn the car on and back off and it will cool off enough to charge faster again. It requires effort, but it works.

What a cluster the car will not even charge right anymore.

 

[azerik]

If you set ‘charge to 100’ it doesn’t show any of that info.

Anyone get the 23B50 CSP installed? Did it help at all with this charging issue?

 

[FPLiptak]

I just had the 23B50 Customer Satisfaction Program service done on 08-November-2023 and I have seen the same decrease in the charging rate at home. I have a Grizzl-E 40 amp charger and it has consistently supplied between 8.0 and 9.0 Kw/hr until now. I started charging the car today and for the first 3.5 hours the charging rate started out at 8.8 Kw/hr for the first half-hour and then dropped to kept dropping until it was down to 6.40 kW/hr

^^^ Sorry to hear you are now one of our group. Got it installed early June and been putting up with crap charging for close to half a year now. Not expecting any fix from Ford as this was their answer for defective hardware before until the government forced them to show some decency. On the bright side maybe it will not catch on fire now beside your home. According to Ford it is now operating as design (re-designed) and is no longer in accordance with your purchase agreement. Just can't make this stuff up. How low do you think they will go?

Thank you for confirming that it’s a software “fix” and soon we will all be able to charge “more safelyier (which is how I imagine the intern who designed this “fix for a hardware problem that didn’t even exist yet” speaking).

 

[kennethjk]

My car went in today for the software fix, I will see if they have now officially derated my Autel even though it had been charging at a full 9.5 kw consistently as it is supposed to.

 

[FPLiptak]

Well, the car finally finished charging just before midnight last night. It took 9.5 hours to charge from 17% to 90% using a 30 amp Grizzl-E Smart Charger.
I looked at the data from September 12, 2023 for comparison and plotted out the charge rate (Kw/hr) based on the "Energy Added" from the Ford Pass app for both charging sessions, Here is the plot:

It started out good but then dropped very quickly from 8.5 Kw/hr to 6.5 Kw/hr.

For the charge on 09/12/2023 it started at 25% and ended at 90% and took 6.5 hours. (before 23B50)
For the charge on 11/13/2023 it started at 17% and ended at 90% and took 9.5 hours (after 23B50).

I also looked back to a charge I did on 09/02/2023 which started at 18% and ended at 90% and it only took 7.25 hours to complete.

I think it is ridiculous for Ford to de-rate my charger from 8.5 Kw/hr to 6.5 Kw/hr. They need to FIX the problem and not just cut the charge rate.

Am I going to see a similar decrease if I use my AeroVironment 32 amp charger???????

Has anyone seen anything similar when using DCFC?

Very disappointed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

As I noted for 6 months now disappointed also. You would think if something is over heating operating at the specifications it was sold at it would be fixed not just the power lowered to the part that is over heating and is unsafe.

If we had a 48 amp charger it would be down to 6.5 Kw and a 33% decrease in charging speed as the title of this thread states. Since you and I use 40 amp we are seeing a 25% decrease.

It is now charging at 32 amp on your 40 amp so AeroVironment 32 amp charge should be similar 0.24 V x 32 amp x 0.85 efficiency = 6.5 KW

DCFC is good here still (tested a few times after installed) and therefore I think it has nothing to do with the pack, HVBJB etc. It is something with the L2 charging system before it gets to what is redundant between the 2 types of charging is my guess. Or crappy software that tries to monitor temps and falls.

Nothing was ever melted here for the first 2.5 years just this software is trying to tell me there could have been .

Edit: 0.24 KW changed to V

 

[FPLiptak]

So, this brings up an interesting question. For those who purchased the hard-wired Ford (or other supplier) 48 amp charger, what is their limitation after the 23B50 "fix"???
