PROBLEM TO BE SOLVED: To prevent the degradation of accuracy in voltage detection, and to avoid a state where energy equalization becomes insufficient since there is no time during a management function operation.SOLUTION: A secondary battery device controls a plurality of cells or a plurality of modules that include the plurality of cells divided into blocks, an execution block 100 for equalizing variations in energy, and a management block 200 for providing control information. The execution block generates an energy state detection signal including information corresponding to each piece of voltage information of each cell and each temperature. The management block decides cell designation information and control time of which variations should be controlled based on the energy state detection signal. The execution block uses the transmitted cell designation information and the control time information to execute energy equalization processing of the cell when operation of management block is at a standstill. |
