Abstract:
This battery monitoring system quickly and accurately grasps the position of a monitoring device that monitors battery packs when an abnormality occurs in the monitoring device. The battery monitoring system is equipped with a comparison unit (21) and a change unit (22). When a battery management unit (BMU) (20) which acquires, from each of a plurality of cell monitoring units (CMUs) (10) that monitor a plurality of battery packs (50) provided with at least one secondary battery cell, battery state information for the associated battery pack (50), activates a particular CMU (10) according to a predetermined sequence, the comparison unit (21) compares the sequence number representing the sequence in which the CMU (10) was activated with an identification number assigned to the CMU (10) acquired from the CMU (10). If the sequence number and the identification number differ, the change unit (22) changes the identification number to the same number as the sequence number, and outputs the new identification number to the CMU (10) after the identification number has been changed.
