BALANCING METHOD OF BATTERY PACK, BALANCING SYSTEM OF BATTERY CELL, AND BATTERY PACK |
摘要 |
PROBLEM TO BE SOLVED: To provide a battery pack and a balancing method of battery cells, for preventing deep discharging of a certain battery cell by balancing of the battery cells which starts near a discharge end point without using an overdischarge control unit. SOLUTION: The balancing method of battery cells includes: a balancing check condition determination step of determining whether a maximum voltage of the battery cells 110 is smaller than a reference voltage; a balancing start condition determination step of determining whether a residual capacity difference or voltage difference between the individual battery cells exceeds a reference value; a balancing time calculation step of calculating a balancing time for discharging the battery cell that exceeds the reference value; and a balancing operation step of discharging the selected battery cell when the battery cells are being charged or are in standby or when a discharge current of the battery cells is smaller than a reference current.
