In my test case last night I was only driving 2 miles away from my house to a local Home Depot - only on surface streets with lots of coasting and braking at stop lights.
Got a lot of regenerative action, yet still the battery percentage displayed went down way more than it should have, however the total range estimate left seemed about right. Also the total energy expended value in the Trip Meter display seemed valid and would result is less drop in battery percentage if used to calculate that from the full charged value of 19.5KWH.
So it appears to me the battery percentage number calculation is just off and can't be trusted as an exact number, the true value is probably higher based on the energy expended total I get from the Trip Meter display.
In my 4 mile (round trip) test last night it should have dropped from 100% to about 95%, as opposed to the displayed 92%.
Sounds like a Ford software bug for the battery percentage calculation to me; it should correlate to the measured energy expended value - unless that is off, but that would result in a much lower total range which wouldn't be right, so I suspect its just the battery percentage display value that is off (too low)
