According to an aspect of the present invention, provided is a power control system for controlling division operation of multiple energy storage devices, which can maximize a power conversion efficiency of the energy storage devices connected in parallel. The power control system includes: a plurality of energy storage devices charging a battery with power or discharging power stored in the battery; and a power management device which, if the whole load factor of the plurality of energy storage devices is less than or equal to a threshold value, determines division operation of operating the plurality of energy storage devices in different time sections during a certain period of time, and determines the number of division operation during the certain period of time, the number of target energy storage devices to be operated by each of the number of division operation, and an operation time of the target energy storage device by each of the division operation number. |
