SPLIT CHARGING/DISCHARGING METHOD FOR SECONDARY BATTERY, BATTERY MANAGEMENT SYSTEM, AND BATTERY PACK COMPRISING SAME

Disclosed herein relates to a segmented charge and discharge method that charges/discharges a secondary battery within a state of charge interval from SOC a to SOC b, including: a charging process for charging the secondary battery; and a discharging process for discharging the charged secondary battery, and the charging and discharging processes are repeated, where the charging process ends charging when a measured voltage value of the secondary battery reaches an end-of-charge reference voltage, and the discharging process ends discharging when a measured discharge capacity reaches a value equal to a capacity Qc charged during the charging process multiplied by the Coulombic efficiency, where a
