Abstract
A charging cable for an electric vehicle includes a power plug adapted to be detachably connected to a power socket of a commercial power source; a temperature detecting unit for detecting a temperature of the power plug; a cable connector adapted to be detachably connected to an electric vehicle for supplying a charging current to a battery of the electric vehicle; and a switching unit for opening and closing a current path between the power plug and the cable connector. The charging cable further includes a leakage detecting unit for detecting an electric leakage based on a current flowing through the current path; and a power cutoff unit for opening the switching unit when the detected temperature of the temperature detection means exceeds a threshold value or when the leakage detection means detects the electric leakage.
