Abstract
There is disclosed an apparatus for precisely regulating, with a simple structure, a state of charge of each of cells constituting a battery set. In the apparatus, a detection circuit, a plurality of discharge circuit connected to corresponding one of the cells, respectively, and a control circuit are provided. The detection circuit detects open-circuit voltage of each of the plurality of cells, the plurality of discharge circuit discharges a charging electricity charged in the cells, and the control circuit controls to uniform the state of charge of each of the cells, utilizing the discharge circuit respectively corresponding to each of the cells, based on the open-circuit voltage of each of the cells detected by the detection circuit.
