Abstract
A storage battery management device manages a plurality of battery units in a storage battery system including the battery units having a plurality of battery cells and a power adjustment device connected to the battery units via respective contactors and connected to a main circuit. The storage battery management device includes a minimum value determination unit and a controller. The minimum value determination unit, from the battery units in which a difference between a maximum cell voltage and a minimum cell voltage of the battery cells forming each of the battery units is equal to or less than a certain value, determines a minimum value of the minimum cell voltage. The controller controls a cell balance process of the battery unit managed by itself, by using the minimum value of the minimum cell voltage determined by the minimum value determination unit as a cell balance target voltage.
