To provide a charging cable capable of flexibly coping with each type of a power supply.SOLUTION: A charging cable 1 includes an input side plug 2, an output side charging connector 4. a relay 50, a voltage detection circuit 10, a GND monitor circuit 20, a relay fusion detection circuit 30 and a control circuit 40. The control circuit 40 determines a determination reference value for performing failure diagnosis of the relay fusion detection circuit 30 based on a first output signal from the voltage detection circuit 10 and a second output signal from the GND monitor circuit 20 before switching the relay 50 to ON in a state in which the input side plug 2 is connected to a power source to determine whether or not the relay fusion detection circuit 30 has failed by comparing a value indicated by a third output signal from the relay fusion detection circuit 30 with the determined determination reference value after switching the relay 50 to ON.SELECTED DRAWING: Figure 4

    【課題】各種類の電源に柔軟に対応することができる充電ケーブルを提供する。【解決手段】充電ケーブル1は、入力側プラグ2と、出力側充電コネクタ4と、リレー50と、電圧検出回路10と、GNDモニタ回路20と、リレー溶着検知回路30と、制御回路40とを備え、制御回路40は、入力側プラグ2が電源に接続されている状態で、リレー50をオンに切替える前に、電圧検出回路10からの第1出力信号と、GNDモニタ回路20からの第2出力信号とに基づいて、リレー溶着検知回路30の故障診断を行うための判定基準値を決定し、リレー50をオンに切替えた後に、リレー溶着検知回路30からの第3出力信号によって示される数値と、決定された判定基準値とを比較することによって、リレー溶着検知回路30が故障しているか否かを判定する。【選択図】図4
