Abstract: The controllers perform a series of charge/discharge processes in which LFP cell is charged to a full state of charge by the charger/discharger, LFP cell in a full state of charge is discharged by the charger/discharger until OCV of LFP cell reaches a predetermined OCV of LFP cell that uniquely represents the common capacity before and after the degradation of LFP cell, and the current integrated value of the discharge current is acquired during the discharge process.
