Battery pack cell balancing method of the same and energy storage system including the battery pack

摘要

The present invention discloses a battery pack, a cell balancing method of a battery pack, and an energy storage system including the same. A cell balancing method of a battery pack according to an embodiment of the present invention includes: measuring a voltage of each of a plurality of battery cells in a battery pack; Selecting a battery cell to be subjected to cell balancing among the plurality of battery cells based on the measured voltage; Selecting a resistance among the plurality of resistors to be subjected to cell balancing; And outputting the voltage of the cell balancing target battery cell from the multiplexer receiving the voltage of each of the plurality of battery cells to the resistance to be subjected to the cell balancing.
