Data flash
Depth of discharge in percent as related to Qmax. 100% corresponds to empty battery.
Depth of discharge that was looked up in the DOD (OCV) table based on OCV measurement in relaxed state.
End of charge
Fully charged
Full charge capacity. Total capacity of the battery compensated for present load current, temperature, and aging effects
(reduction in chemical capacity and increase in internal impedance).
