Operating power is constantly supplied to the battery ECU (2a) used as a master while being supplied to the battery ECUs (2b to 2f) used as slaves through a relay contact (16). When a vehicle stops running, the master battery ECU (2a) controls the relay contact (16) to be turned OFF after collecting necessary data of each of the slave battery ECUs (2b to 2f) to store therein. When the vehicle restarts running, the master battery ECU (2a) turns the relay contact (16) ON to transmit the necessary data to each of the slave battery ECUs (2b to 2f).",
