Is a fall from 95% to 90% SoH a 5% loss?
Percentage points and relative percentage changes are easy to confuse. What does each description mean when both readings share a valid baseline?
EVVerity explains
A closer look
The percentage-point difference
A change from 95% to 90% is a fall of 5 percentage points relative to the original reference. In an illustrative 60 kWh baseline, the corresponding figures are 57 and 54 kWh, a difference of 3 kWh.
The relative change
Relative to the earlier 57 kWh figure, a 3 kWh decrease is about 5.26%. State which comparison you mean and retain the uncertainty of the readings. Neither wording proves a smooth degradation trend between the two assessment dates.
