Abstract
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 (T1). 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 (T2) or lower, the specified temperature (T2) being lower than the specified temperature (T1).
Claims9
A charging cable for an electric propulsion vehicle used for charging a battery for the electric propulsion vehicle, the charging cable comprising:
- a power plug detachably connected to an electric outlet for a commercial power supply;
- a charging plug detachably connected to the electric propulsion vehicle;
- a temperature detection unit that detects ambient temperature;
- and
- a control unit that generates and transmits a pilot signal for adjusting a conduction current to the battery, to the electric propulsion vehicle,
- wherein the control unit stops electric conduction to the battery when the detected temperature detected by the temperature detection unit is equal to or higher than a predetermined, first specified temperature, and recovers the electric conduction to the battery when the detected temperature decreases to a second specified temperature or lower, the second specified temperature being lower than the first specified temperature.
