Provided is a contactor failure determination device for a vehicle capable of appropriately determining a failure of a contactor provided in the vehicle. A detection device capable of detecting an increase or decrease in a voltage of a second circuit including an external charging device is provided, and when an external charging request is issued, a first control for closing each external charging contactor is implemented, and a second control for closing the pre-charging contactor is implemented after the first control is implemented. After the implementation of the second control, a third control for closing the second main contactor is implemented, and when the detection means detects that the voltage of the second circuit does not increase after the implementation of the third control, it is determined that at least one of the external charging contactors is in an open state.

    提供一种能够适当地判定设置于车辆的接触器的故障的车辆的接触器故障判定装置。设置能够检测包括外部充电装置的第二电路的电压的增减的检测装置,当发出了外部充电要求时,实施使各外部充电接触器闭合的第一控制,在该第一控制的实施后实施使预充电接触器闭合的第二控制,在该第二控制的实施后实施使第二主接触器闭合的第三控制,当通过检测装置检测到在第三控制的实施后第二电路的电压没有增大时,判定为至少一方的外部充电接触器以打开的状态产生故障。
