My GTPE loses charge while on Level 1 EVSE

[Mach-Lee]

It’s normal for the coolant to get churned up while the pumps are running. It squirts out of the upper tube in the tank and hits the tank contents with velocity.

For a failed coolant pump, I would see SOBDM internal temps exceeding 80°C, coolant pump and radiator fan commanded high, but no activity in the coolant tank and temps will not come down. See this for desired operation:

The firewall tank is for the battery and heater. The passenger fender tank is the one that cools the charger, motors, and radiator. So you are interested in that one (the one that was low). If you listen close you should be able to hear the coolant pump running when the charger gets hot.

You might also try a 12V reset by removing the negative terminal (10 mm socket) for 10 minutes.

@Mach-Lee, man I’m so glad that you chimed in here
I’m sitting in the garage and the car seems charging, just did 59%->60% SoC and it’s quiet here. I’ll go for a quick run to do a DCFC and then try to charge on AC at a higher state of charge. But so far it looks promising.

Thank you so much!

Reporting here, after a quick DCFC session 60 to 80% SoC I returned back and started charging on AC and car no longer spins fan as crazy. Will monitor for day or two and report back.

Thanks!

very useful information!!

Ok guys, bad news. The car started to act up again. I reenabled charging locations and set mine to only charge from 00:00 to 3:00pm and connected it to a 3kW EVSE (220V 16A). The initial SoC was 80%, by the time (4:10am) I stopped the charging it was 81% SoC. The ambient temp in the garage went from 71.8F to 77F, so I technically can use the car as a space heater

screens attached.

Hey everyone,

Recently a very strange issue started to happen with my Mach-E. It looses SoC during overnight charging at home on Level 1 charger.
Let’s say I plug it with SoC of 86%, then in the morning it displays 81% SoC after 4 hours of being connected to Level 1 120V EVSE.

Also it produces a ton of heat and warms up my entire garage and makes it very noisy there due to running fans non-stop.

I took it to the dealer, told them that it loses SoC while on level 1, showed them videos of car spinning fans and cycles coolant non-stop and of course the outcome is nothing. They simply hooked it up to a level 2 EVSE and found nothing and said that vehicle is ok at this time. I had no time to argue so I picked the car up.

Did anyone come across the issue like mine?

thanks in advance!

PS: DCFC seems to work just fine. Level 2 10kW seems to be slower now and also makes car to generate heat and spin fans like crazy.

One thing to remember is that MME displays % battery charge, which is based on temperature. It is not displaying kWhr. As your garage and battery heat up the capacity of the battery increases. So the same amount of charge registers a lower %. I wish we had an easy way to measure the amount of energy in battery.

I understand that, there is an instrument cluster displayed SoC and real battery SoC available via obd2 scanner. I live in bay area, so there is no dramatic temp fluctuations as like in Canada or Siberia

What I also noticed is that car can’t predict when it will complete charge. Basically it’s guessing, e.g. it tells you that it will complete charging in 2 hours, but SoC is 70% and car is connected to a level 1 charger.

on top of that the car battery may be at 100% SoC, but it’s actively charging beyond 90% limit (see screenshot)

I also noticed that car can’t detect the EVSE type and Forscan kinda proves that (I highlighted params on the screenshot)

My 2022 AWD standard range has started doing this in the last couple of weeks on my L1 charger (Ford mobile). It doesn’t even charge to 90% most days, even when it starts at 80%. Frustrating for sure. I am on 6.13.

My 2022 GT is having the same issue for the last few weeks. Charging gets stuck at 88% where 90% is the set limit, and the entire garage is very warm. Is there any solution to this?

Even the in the heat of summer, my garage temp change was noticeable, but not remarkable. (i.e. way, way less than the change brought on by pulling a 5.0 GT ICE into the garage) I rarely heard the fans on the 110V charger. Even at 32A, my L2 hasn’t been spinning up the cooling system much in this season. I think a call to the BEV team might be in order. Under no normal circumstances should charge decrease overnight if you are truly delivering power to the battery.

I am also experiencing this issue outdoors on my 2021 Premium. Was not happening last year or any time prior to this fall.

Kronstein was first to have this problem, but people are posting more in the other thread. There is a fix but you have to take it to the dealer. See this thread:

I’d refer to the thread you mentioned as a main thread about the issue, but there’s no fix unfortunately.

on top of everything I’m getting enormous electricity consumption numbers during the charge on low powered L2 and high powered L2 as well due to battery heating/cooling.

as you see my Tesla wall connector (48A) has delivered 42.5kWh only to top off 33% which roughly is 30kWh +/- 10%

So technically even if you haven’t noticed the discharge of HVB you will see it on your electric bill.
