PROBLEM TO BE SOLVED: To make it easier to identify a failure cause of a contactor.SOLUTION: A contactor failure determination device 10 determines a failure of a contactor group including: a positive electrode side contactor 30 provided on a positive electrode side power line L1 connecting a positive electrode of a battery 22 supplying electric power to load equipment and a positive electrode of the load equipment; and a negative electrode side contactor 32 provided on a negative electrode side power line L2 connecting a negative electrode of the battery 22 and a negative electrode of the load equipment. In the case where abnormality of a driving circuit voltage of any contactor occurs during a start-up of the load equipment, the contactor failure determination device 10 determines that there is a possibility that the contactor driven by a driving circuit has a failure caused by the driving circuit.SELECTED DRAWING: Figure 1

    【課題】コンタクタの故障原因を特定しやすくする。【解決手段】コンタクタ故障判定装置10は、負荷機器に電力を供給するバッテリ22の正極と負荷機器の正極とを結ぶ正極側電源ラインL1上に設けられた正極側コンタクタ30と、バッテリ22の負極と負荷機器の負極とを結ぶ負極側電源ラインL2上に設けられた負極側コンタクタ32と、を含むコンタクタ群の故障を判定する。負荷機器の起動中にいずれかのコンタクタの駆動用回路電圧に異常があった場合、当該駆動用回路で駆動されるコンタクタに当該駆動用回路に起因する故障の可能性があると判定する。【選択図】図1
