A temperature detection unit detects the temperature of a power plug. A control unit stops electric conduction to a battery when the detected temperature detected by the temperature detection unit is equal to or higher than a predetermined specified temperature (T). The control unit recovers the electric conduction to the battery when the detected temperature detected by the temperature detection unit decreases to a specified temperature (T) or lower, the specified temperature (T) being lower than the specified temperature (T).

Charging cable

A charging cable for use in charging a battery of an electrically-driven vehicle includes a power plug 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 sensor for detecting a temperature of an electric circuit between the power plug and the charging coupler, and a charging device having a controller for controlling a current value that flows from the power plug to the charging coupler. This configuration can minimize the charging time and enhance the durability between the charging cable and the receptacle outlet and between the charging cable and the charging coupler.

Charging cable for electrically-driven vehicle

Disclosed is a heat radiation device, which is in contact with a first heat-producing component having a higher value of guaranteed temperature and a second heat-producing component having a lower value of guaranteed temperature, and the heat radiation device comprises a metal member provided with a slit. The metal member is divided by the slit to have two heat radiation regions, a first heat radiation region and a second heat radiation region that are loosely coupled with each other in terms of heat conduction. The first heat-producing component is placed in contact with the first heat radiation region, and the second heat-producing component is placed in contact with the second heat radiation region.
