ABSTRACT:
To provide a voltage measurement device for measuring a battery voltage of a secondary battery formed by serially connecting a plurality of battery blocks, which is able to calculate the battery voltage in block units even though a potential detection line is disconnected. Specifically, when the voltage detection unit fails to measure the battery voltage of the measurement target battery block by selecting potential detection lines connected to both terminals of the measurement target battery block, the switch control unit selects the potential detection lines connected to both terminals of the battery block group including a serially connected plurality of battery blocks including the measurement target battery block, then measures the integrated voltage of the battery block group, and measures the battery voltage of the measurement target battery block based on the measured integrated voltage.
