Innacurate charge completion estimates with FCSP

[Pioneer74]

Is anybody else getting wild and innacurate guesses on when your truck will reach your set charge level using the FCSP? I never had these messages using my Emporia charger.

Before my 11:00pm scheduled time to start, it guesses that it will take until 6am to finish. I don't have a screenshot of that. When it starts charging, it then estimates it will take to almost 4:30am.

Now, I'm at 44%. Charging to 85%. Let's do the math.

85% - 44% = 41%

131,000 * .41 = 53,710

I've seen a charging rate on my FCSP of around 17,500 kWh. So....

53,710 ÷ 17,500 = 3.06 hours.

Sure enough, at 2:30am the truck reaches my set limit. But what's even more strange is less than an hour after it starts charging, it alerts me that it will have to charge outside of my charge window to reach my set limit. My window ends at 6am.

I'm afraid with how bad this this is estimating my charge time that one night I'm going to plug in and it's going to start charging before my "super off-peak" window and I'm going to lose my rate and incentive.

So am I the only one having this happen?

No, you are not the only one. FordPass isn't very good at estimating completion time. That said, perhaps if you keep using that charger it will learn (we could hope).

It won't. I spent about a year charging at work on a 6kW charger, It always showed estimated completion about an hour longer than actual completion. Some aspects of Ford software are sub-optimal.

My guess: FordPass uses real time data, thus the estimated charge completion time is a moving target based on the charge rate at the time you look at the eta.

The first picture below shows the Power/Volts (the amps are low because I can only find one of the two onboard charger PIDs) accepted by my truck from my FCSP at a ~30% SoC. I think my FordPass will initially give me a charge completion eta braised on this charge rate.

This is my charge curve at the end of my session from ~80% to 100% SoC. I’ve noticed my FordPass charge completion eta gets pushed out, especially at the top end (over 80% SoC). My guess the app used the current Power delivered and recalculates….
