You don't fill it lost all that capacity because when new the car doesn't use all its capacity (car stops with 0, 0 % Soc but with high voltage in the cell, surelly over 3,6 V).
Malm, you think this is the way that iMiev hides capacity in the first years?
If you are right then the CellVoltage as a function of a fixed %SoC should be an indication of real iMiev battery capacity?
For example for 17% SoC (1 bar) the CellVoltage should drop from something like 3,7V when the car is new and hiding capacity to 3,5 V when the car has shown all its capacity.
My iMiev with now 111k km show around 3,6V CellVoltage for a 17% SoC reading.
