1. A charging cable for use in charging a battery of an electrically-driven vehicle, the charging cable for the electrically-driven vehicle comprising:

  • a power plug adapted to be detachably connected to a receptacle outlet of a commercially available power source;

    a charging coupler to be detachably connected to the electrically-driven vehicle;

    a temperature detector operable to detect, when the battery of the electrically-driven vehicle is charged, a temperature of an electric circuit between the receptacle outlet and the charging coupler; and

    a controller operable to generate a pilot signal indicating a charging current to the battery based on the temperature detected by the temperature detector to send the pilot signal to the electrically-driven vehicle,wherein the controller sends, when the temperature detected by the temperature detector reaches a predetermined threshold value, a pilot signal that has been changed in waveform to the electrically-driven vehicle to notify the electrically-driven vehicle to reduce the charging current.
