Title: RELAY DEVICE
Abstract:
Provided is a relay device which is applicable to a system that may supply power to a load through at least two power storage units, and which, if an anomaly such as an open failure occurs in the path of either of the power storage units, may detect the anomaly more accurately. A control unit (12) provided in the relay device (10) functions as a switching control unit, and, if a current value is lower than a predetermined current threshold value in one path among a first conduction path (51) and a second conduction path (52), switches a relay unit (either of a first relay unit (41) and a second relay unit (42)) which is disposed on this path to an OFF state. Furthermore, the control unit (12) functions as an assessment unit, and, if one of the relay units has been switched to the OFF state, assesses whether or not a voltage value detected by a voltage detection unit (either of a first voltage detection unit (21) and a second voltage detection unit (22)) that is on the path of the relay unit, which has been switched to the OFF state, is lower than a predetermined voltage threshold value.
