PROBLEM TO BE SOLVED: To improve reliability by enabling the determination of a failure in a charging start signal circuit.SOLUTION: A failure diagnosis device is the device for a vehicle charging system to charge an on-vehicle battery from an external power source by connecting a charging gun 3 to an on-vehicle charger 2. The device includes a startup circuit 20 for outputting a charging start signal to a control unit 1 of a vehicle that controls charging from the on-vehicle charger 2 when the charging gun 3 is connected to the on-vehicle charger 2, so as to start the control unit 1. The control unit 1 has a failure determination function of allowing the on-vehicle charger 2 to output a charging start signal with the startup of the on-vehicle charger 2 by the turn-on of an ignition switch 11, and determining that disconnection or short-circuit occurs in a charging start signal circuit 5 of the startup circuit 20 when the charging start signal is not input to the control unit 1.

    【課題】充電開始信号用回路の故障判定を可能にして信頼性を向上させる。【解決手段】車載充電器2に充電ガン3の接続により外部電源から車載電池を充電する車両の充電システムの故障診断装置であって、車載充電器2に充電ガン3が接続された際に、車載充電器2から充電を制御する車両のコントロールユニット1に充電開始信号を出力してコントロールユニット1を起動させる起動回路20を備えており、コントロールユニット1は、イグニッションスイッチ11オンによる車載充電器2の起動に伴って当該車載充電器2から充電開始信号を出力させ、コントロールユニット1に充電開始信号が入力しない場合に起動回路20の充電開始信号用回路5が断線または天絡であると判定する故障判定機能を有する。【選択図】図1
