To a point around 95% or so it starts slowing down if you are giving to all the amps
True, I noted this in another test on the following post.


95% ---> 99% note the charger ramping down as each percentage point is reached, The second peak current is when remote start clicked to warm the cabin, ran it for 30 minutes.

Yours seems to be a bit off normal. That said, there are many cases of discrepancy for various reasons.
I believe the FordPass number only shows what is added to the battery. It doesn't show what is used by the truck to keep things warm. Last night my FordPass recorded 54.9kwh added and my Emporia recorded 59.6kwh which is a normal 8-9% loss rate. It was warmer last night and there were no heater spikes since I had the charger set to 32 amps and it took most of the night to charge. The night before it was much colder and I drove much less that day. Charging was done early with Fordpass recording 7kwh to the battery and Emporia recording 13.5kwh used. I had about 4kwh of heater spikes through the night after charging according to Emporia. I did not have a departure time set.
If you have a departure time set, the truck can use quite a bit more power as it preconditions. This also won't be recorded in the FordPass charge history since that only records energy to the battery.
