Storage battery apparatus

According to one embodiment, a storage battery apparatus includes: a plurality of storage battery modules each including a battery module, which includes a plurality of battery cells, and a cell monitoring unit measuring voltages of the battery cells and a temperature of the battery module; and a battery management unit periodically receiving measurement values of the voltages of the battery cells and the temperature of the battery module. When there is interference in communication with the plurality of cell monitoring units, the battery management unit extends a communication cycle with the cell monitoring units, sets a value of a chargeable current and a value of a dischargeable current of the battery module, which correspond to at least the communication cycle.
