Abstract
A switch element is configured to decrease an impedance of a voltage-detection integrated circuit that detect voltage between both ends of unit cells of a higher-ordered battery block, for adjacently-connected pair of the higher-ordered battery block and a lower-ordered battery block. The voltage-detection integrated circuit is configured to detect disconnection of an electrical wire when voltage between both ends of a lowest-ordered unit cell that is detected with the switch element turned on is equal to or lower than a threshold.
