The diagnostic data provided by the BMS does not include the SOH. It only has the min and max deterioration data from the total capacity.
After nearly 3 years of monitoring this data we were able to conclude that the SOH number as checked by a Kia service tech is actually a computed value. It is the average of min and max, taken away from 110. At Kia service any number greater than 100 is shown as 100%.
For the next two years you will have to ignore these 'false' positives.
In the graphic above SOH is really 100%, SOH in kWh is really 27kWh and Lost SOH is really zero.
So in my case, SOH is really 100% (at 110% shown), SOH in kWh is really 27 kWh (at 29.7 kWh shown), and the Lost SOH is really 0% (at 10% shown). Remember that with my old (original) battery pack, Torque was showing anywhere between 79.4% to 91.7% SOH, even though the actual value measured by the dealership was 66.5% SOH.
Now these values have changed in Torque (after the DCFC experiment), I'm guessing that the actual values have also changed to "something" below 100% SOH. Think of these as "relative" measurements.
