L2 charging speed recently dropped 33%

[Bikespace]

...
On my car when I charge at 43amps (it fails at anything higher), the EVSE is delivering 10.3kwh but the ford pass will show 9kwh.

Have you brought this concern to your dealer's attention? This was exactly the issue my GTPE had. It would fault, and red-ring after three failed attempts, at anything over 32 Amps. We only figured it out because we used an OBDII reader to watch it fail in real time.

I think it simply truncates. 9.2 KW would show 9, not 8. At least that’s been my experience.

My experience is if it's x.5 - x.9 it will show X, while if it's x.1 - x.4 it'll show 1 kw lower.
So if it's 9.5 fordpass will show 9, but if it's 9.3 fordpass will show 8.

When I charge at the local free L2 chargers that are 6.2 or 6.3kwh, fordpass shows 5kw, the chargepoint/blink apps will show 6.2 or 6.3 being delivered, carscanner will show about 6 to 6.1 going into the battery, but fordpass shows 5kw.

Yes, they can't duplicate as they only have a 6kw L2 charger available to them. So since they can't duplicate, they won't look into it, even when I show them videos, photos etc.

If I set my EVSE at anything higher than 43 amps, my MME will charge for 2-3 minutes then stop with the red ring. Unplugging and plugging back in will get red ring. Have to unplug for about 10 minutes then plug back in for it to start charging again. But it will fail again after 2-3 minutes if it's higher than 43 amps.

It's not EVSE issue as it has no issues charging at the full 48 amps with several Ford F150 lightning, loaner MME I had during recall work, and BMW i5, ix loaners.

I've tested my MME on a Ford pro 80 amp charger and it fails as well. So it's definitely something in the car.

Dealer won't look at it and now that it's out of warranty, they say they can try to look again but wants $225/hr to diagnose.

Wow….#FORDMATH. ?

FordPass shows what’s going into the battery. A smart EVSE will show what’s going into the truck- it will be more than what FP shows.

Not necessarily correct. I've tried monitoring using carscanner, and what carscanner shows going into battery is about 200 watts less than what my EVSE shows going to the car. Fordpass on the other hand shows about 1-2kw less.
So in my test case, EVSE shows 9.3kwh going to the car, carscanner shows 9.1 to 9.2kwh going into battery, fordpass shows 8kw.

And this is why folks hate dealerships.

Escalate this to Ford customer service. I thought it was BS that I had to bring my own EVSE to them, but at least they had a properly wired NEMA 14-50 receptacle, and could duplicate the problem at the dealership.

Find a different dealership if you need to. That one does not deserve your business.

Already tried 2 dealerships and called ford corporate. Corporate said there's nothing they can do if the dealers don't have the proper equipment to duplicate the issue. They just suggest talking to the service manager and/or general manager of the dealership (completely useless).


Both dealers only have the 6.2/6.3 kwh chargepoint chargers on their lots. there aren't any public L2 chargers that do more than 43 amps near by and they refuse to come out to my house to see the issue.

The ford pass app rounds down. So if you're charging at 9.2kwh it'll show 8kwh in the app.
So if you're on a 40 amp 240v L2 charger, it

Really? You sure?

My EVSE is sending about 9.4kWh while the car is reporting 8.8kWh via FordPass. The difference is energy loss in the cars charging inverter. It’s not rounding.

Yes I'm sure. My fordpass app (both the old and the new 5.2) doesn't show any decimal places. The charge rate are always displayed in whole numbers and rounded down.

That is frustrating. You need to find a hard-wired 48 Amp EVSE (on a 60 Amp circuit) to see the issue. Even if you bring an EVSE to their (properly wired) NEMA 14-50 receptacle, it will max out at 40 Amps, and not duplicate the issue.

Are there any dealerships nearby that actually invested in chargers? To late to solve my problem without my own equipment, my dealer put in a new row of L2 chargers, and even the L3 DCFC that was (originally) required to be part of Ford's EV future.

Odd that it’s truncating or rounding for some but not others. Regardless, the number reported by FordPass represents the power getting into the battery after charger losses and will always be a bit lower than what the EVSE is supplying. Someone did a graph showing the charging losses at different L1 and L2 rates. Not sure where it is.

I think it simply truncates. 9.2 KW would show 9, not 8. At least that’s been my experience.

You also have to remember that it is 8 into the the car and it needs to be divided that by 0.87 (87% efficiency) to get what the charger is providing. 240V x 40 amp = 9.6 KW 9.6 x 0.87 = 8.3 KW into the car. That is what I got for the first 2.5 year's of owning the car after the 6.6 (tsb) module updates it is at around 6.5 into the car for the last year plus. Sick move on Fords part. Like not replacing faulty junctions boxes and installing limp mode charging.

Many times appears Ford direction is do nothing and F the owners.

Just take total % chargers x 88 KW battery capacity divided by time it took to get an average charge rate mine is low 6 KW since ford installed the FU software.

My dealer has a Ford 48 amp hardwired but will not test it as Ford knows the problem and ford will not pay them for the their time. It is a Ford directive to F owners nothing dealers can do about that.

After an update last year, my max charging rate dropped to 6 KW. Somewhere along the line, it went back to 9-10KW. I have no idea which update “fixed” the problem. Other than the BC updates, my car is pretty well updated.

Thanks for the info sounds like their may be hope. The update that slowed it down here happened June 2023 and it is still charging low 6 KW. I can say the Tesla update did not do it. Have not received much more in the form of updates here for a year. May be it is like a year dealing with a fried HVBJB or the year with no departure scheduling? It may be fixed soon. Right now with all that transparency I am not 100% sure.

Mine definitely was corrected before the Tesla update.
