<p>A voltage detection device (1) includes: a plurality of voltage-detecting ICs (21 to 25) installed in order to detect voltages of a plurality of blocks (B1 to B5) of a secondary battery (10), each of the voltage-detecting ICs being installed for each of the blocks; and an interruption control unit (41) that controls interruption operations of the voltage-detecting ICs. After resetting all of the voltage-detecting ICs (21 to 25) by transmitting a trigger signal to all of the voltage detecting ICs, the interruption control unit (41) transmits a control signal in which an address of a voltage-detecting IC allowed to execute an interruption operation is designated. Each of the voltage-detecting ICs (21 to 25) receives the control signal within a designated time set in advance, executes the interruption operation when an address of its own is designated, and is left reset when the address of its own is not designated.</p> |
