Strange charging estimation to full charge on L2 - 36 hours instead of 4 hours normally ?

[metroshot]

Yesterday - for my once a week charging routine at home (L2), I plugged in and Ford Pass app said full charge will be the next day (36 hours).

I found that odd as I normally charge fully after 4-5 hours.

My charger app showed full rate (11kW) consistently for 4 hours (44kW).

After 5 hours, app showed full charge of 100% but my app said tomorrow night will reach full charge...

Anyone see that ?

Last download was OTA 4.1.3 about a month ago.

Have charged fine at home once a week since the update -

Just yesterday the estimation had me worried at first thinking my L2 charger wasn't putting out.

Since it is pumping out 11kW, the charger is ruled out.

Is it possible that the battery cells/modules may be going bad which is why the estimation would take so long to charge fully ?

What APP version are you running 4.24.0 [android or ios version]?

The likelihood is that it's just the crappy FordPass app. 99.99999% likely.

Simply walk over to the vehicle (or check the charger via its app). It's either charging, or it's not. If it's not charging (i.e. it is done), then it's simply a crappy app. Nothing more than that.

Where do I find the app version on an iOS device ?

I found something odd when I started to look around - privacy settings showed an error sign:

Hopefully an experienced IOS user can give you some tip's, but for android devices I can go into the APP control panel to determine a variety of settings and the version number.

The number might be slight different for either platform depending on when application development rolls out an update to the ios-app-store & android-play-store respectively.

The one thing I've always experienced is that the FordPass app always over states the duration of time required to complete a charging session from current SOC to target SOC, I think the calculation is based on the FMC rate of charge ~32 amps at 240v.

My FCSP running at 80 amp setting actual throughput of ~75 amps often finishes well before the projected time frame.

My charge completion time has never been accurate on the FordPass app. I wouldn't worry about it. It's never been off as much as yours, but it's generally a couple hours off.

Just out of curiosity, how does the truck know the output of the EVSE for the calculations. If I were to upgrade my unit would I have to edit a setting?

The truck knows the power it is getting. The app can't forecast worth a damn regardless of the power level. If you use 120v charging, it's even worse.

People have a huge concern with FordPass and accuracy. It doesn't have it, period. Calling dealers, calling Ford, all a waste of time.

The SOC starting point to the programmed end point SOC then a fixed factor for an EVSE of a certain KW output, it would be nice if the J1772 negotiation included values of what the EVSE can deliver vs what the truck can process at the inverter(s)

Sometimes when my SOC is fairly low the truck tell me it cant reach my desired SOC in my time window and then it starts charging immediately. It appears it using calculations based on 32 amps. I was just wondering if i speaker to 40 or 48 down the road it would know

I don't know how it calculates that. Yes, if it doesn't think it can make it, it will start outside the charge window (which is why my charger is also set to only my off-peak hours). But if you changed it to 48amps, would it not do that? Don't know.

ok thanks. my lectron has no capability to set its own time window.

I believe that's what it's doing...or at least supposed to be doing.

The vehicle shouldn't be calculating charge time based on a static amps assumption. I think the estimations are off because the cells are being trickle charged and balanced at the end of the charge cycle. Regardless, one can verify if the estimation is using a static number or not with some mathematical calculations.
