Abstract
A voltage measurement device measures the voltage of at least one of series-connected battery cells, and includes one or more voltage detection circuits. Each voltage detection circuit includes: a first communication path; a mode control circuit that switches a mode of operation of the voltage detection circuit between normal and low-power modes; a first communication control circuit (communication control circuit) that transmits and receives a command signal to and from the first communication path; an activation signal detection circuit that detects an activation signal input from the first communication path; and an alarm generation circuit that, in the low-power mode, generates and outputs an alarm signal indicating an anomaly in the battery cells to the first communication path. In the low-power mode, when the activation signal detection circuit detects the activation signal, the mode control circuit switches the mode of operation to the normal mode.
