Abstract

The storage battery system includes a storage battery comprising a plurality of battery modules; a plurality of voltage monitoring circuits for monitoring a voltage of the battery module; and a control device that controls charging and discharging of the storage battery on the basis of monitoring information that is obtained by carrying out communication with the voltage monitoring circuits, wherein the control device comprises a determination unit that calculates an estimated output voltage of the storage battery by using the monitoring information that is obtained from any one of the voltage monitoring circuits before occurrence of a communication failure in a case where the communication failure with any one of the voltage monitoring circuits occurs, and compares the estimated output voltage and an output voltage of the storage battery after occurrence of the communication failure to determine an abnormal site of the communication failure.
