Thanks for the info. That's inexpensive enough that I may do some more complex monitoring down the road...
Why would I complain about that? I wish you all the luck in the world.
As expected, after the power cycling of the FCSP, the yellow derate lamp is off and I'm getting next best performance from the EVSE, 96.25% is sufficient in my use requirements, it may not be perfect but realistically it is acceptable, we don't need moon-shot precision & performance.
Interesting that it would bump up and then drop. It should certainly support the 80 amps until 92-93%Yesterday afternoon, I experimented with adjustability of the apm rate on the FCSP, short story ... it still is unpredictable with increasing the value after a reduction of the rate, just as the OP and others above have observed.
I lowered the rate to 48 amps, prior to plugging in, the value change took hold and stayed put through the bulk of the charging session. NOTE (the 10.3 kW DC vs. 11.3 kW AC is normal conversions losses)
As my SOC was approaching the 90% goal, I tried bumping the rate up while the session was still active as I've done in the past, but it would only hold for about a minute or so, then the rate would decrease to lower value.
Tried at 75 amps but it wouldn't hold for long
Tried 79 amps just under the peak value still wouldn't hold long.
End of session snap shots of amps & total kWh's consumed for an 80% to 90% charging session.
After unplugging, I returned the value to 80 amps yesterday afternoon.
This morning I power cycled the FCSP to prepare it for this afternoon's session.
I expect energy flow at a normal 76/77 amp rate (set for 80) as it has over the past 3+ years.
Please note this issue is not related to high SOC tapering down process, the EVSE simply won't hold the requested bump up manually requested from the Ford App control panel of the FCSP settings screen.Interesting that it would bump up and then drop.

yeah, still odd that it acts like it takes and then says just kidding. If anything I figured it wouldn't even acknowledge the change which is what I got anytime I've tried changing it (up or down)
It will perform similarly or slightly less with regards to 80 amps vs some slightly lower value, accept what comes of it and move on.
How did you get a replacement from Ford? My FCSP also has a yellow light while charging, and when I finally talked to Ford they told me I had to wait for a software update and it was a known issue. I had to open the FCSP and d bump down the max current setting to keep it from tripping.
Back to normal at least
