Abstract
A battery bank control device is provided for setting a power limit value of a battery bank in which a plurality of battery racks (BRs) are connected in parallel. The device includes: a voltage measurement unit measuring a voltage of each BR of the plurality of BRs; a first power limit calculation unit calculating a first power limit value according to a state of charge (SOC) calculated based on the voltage of each BR with respect to each BR; a capacity ratio calculation unit calculating a capacity ratio of each BR based on capacity information of the plurality of BRs; a second power limit calculation unit calculating a second power limit value using the capacity ratio and the first power limit value of each BR; and a battery bank power limit calculation unit calculating a battery bank power limit value using the second power limit value of each BR.
