Charge Issue with Mobile Power Cord

[Farmford42]

I was in a remote location this weekend and hooked up my Mobile power cord to a 40a 220vac circuit that I have used before. I was plugged in for 43hours and 18 min and came back to 67% charge. I could not see any issue with the power, or the cable or the connection. When I charge here its usually from about 60 miles of range remaining. Does anyone know if there is a way to get more details from the charge log about why it did not charge fully? The location is set to charge to 100% and has before.

What is your MTE showing after the 43 hour charging session?
What is was the SOC %% with those remaining 60 MTE when your started charging?

Do you have unlimited time constraints for the location?

Can you send a snap shot of the Fordpass charging log entry?

Here is the Ford pass entry. It was plugged in for43 hours. I was at 27% or under 50 miles when I plugged in. It was cold the first night at 18 deg. I have charged here before and I had told the truck to charge to 100%. I have a location set and that also says to charge to 100%. No cell service so the fordpass has some trouble but it’s worked before.
@Ford Motor Company the charge info could have more details.

40% charge in 43 hours almost sounds like you were charging with 110V. Are you sure both legs were hot on the receptacle?

I did not check that box so I can’t say. The rest of the 220 vac equipment worked beyond that point. The well pump etc. i wonder if the truck data would be able to see that. I am planning to call the ev line tomorrow and see if they can see anything. I am charging the truck now on the mobile charger on 220 and it seems to be acting normally.

Did you check the voltage going to the plug during charging? Possibly in the "remote" area you were in you weren't getting full 240 volts due to the higher loads as a result of the cold weather. I am not sure but the well pump may be able to run on the lower voltage.

 

[Farmford42]

I did not go back and check voltage after I saw that it hadn’t charged fully. It’s possible that one leg to that plug was low and the rest of the items I used all weekend were on the other two so everything else worked. There is 3 phase up there. 3 phase pumps working , our well working. I did test voltage at the house and got 120 when a breaker tripped but that was due to another issue.
If there was one leg at 110 v or so how would the truck react?

Just spitballing here because it really does seem like you charged using one leg @ about 52 kWh in 43.3 hr, a 1.2 kW consumption before losses.

What are your weekday settings at that location, max SoC? What happens when you start the charge on a weekday and transition to the weekend setting? Does it go from say charging to 60% to the new 100% weekend setting? I've never thought about it because I have FordPass set to honor utility rates and it carries over.

It looks like you're only charging at a 110/120v rate given the stat's posted.
Double check the output at the 220/240 plug across the legs and to ground/neutral.

 

[Farmford42]

The one leg idea makes a ton of sense. It’s about 3 hrs away so I can’t just run up and double check the power. It’s not a setting issue that I can find. Does anyone know if the mobile charger would work in that situation? ( one leg low or down with the 14-50 plug attached ? ) I wonder if the truck data would see it. Would be great if the charge log would show more information and details.

That is very true, and you would think it would be easy to program. I suspect the mobile charger doesn't care which dongle is plugged in, and uses 240v if it arrives, or 120v if it arrives.

That’s true regarding voltage. The dongle does determine the current. The 120V dongle limits to 12A, even if 240V is applied…the 240V dongle would call for 32A even if 120V applied.

If the 240V supply is missing a leg, the charger will see 0V and it won’t charge at all. But if the voltage leg to leg was 120, it would try to charge at 120V, 32A.

Another possibility, but probably not as likely is that the truck was consuming more electricity to keep the battery warm. The last time I tried my mobile charger at 18 F it quit and had a yellow fault light. The truck reported it was plugged in, but not charging. The charger worked fine for 8 hours or so (until the pack got too cold?) and the stopped charging. I wasn’t plugged in long enough to see if it would have started charging again if the temps came back up to something more reasonable. The mobile charger works fine above freezing, but seems to be lacking when the pack temps get pretty low. I thought my mobile charger must be faulty, but perhaps something similar occurred with yours?

 

[Farmford42]

Thats interesting as well. It was cold one night. I wonder how to test that? Again @Ford Motor Company it would be good to get some diagnostics available to users.

 

[Grumpy2]

Wow, that is interesting:

the 240V dongle would call for 32A even if 120V applied.

If the 240V supply is missing a leg, the charger will see 0V and it won’t charge at all. But if the voltage leg to leg was 120, it would try to charge at 120V, 32A.

So one leg would need to be shorted to ground for the charger to supply power, and it would call for up to 32 amps in that case?
