The system comprises a sensor coupled to the plug and having an output indicative of the temperature of the plug, and a current interrupting device coupled to the sensor for interrupting current in the cable when the temperature reaches a predetermined temperature.
Claims20
A system for interrupting current in an electrical cable having an end plug, the system comprising:
- a sensor coupled to the plug and having an output indicative of the temperature of the plug;
- and
- a current interrupting device coupled to the sensor for interrupting current in the cable when the temperature reaches a predetermined temperature, wherein the predetermined temperature is in a range of about from 80° C. to 150° C.
A system for interrupting current in a vehicular recharging cable having a plug, the system comprising:
- a temperature sensitive device encased in the plug and having an output indicative of the temperature of the plug;
- and
- a current interrupting device coupled to the temperature sensing device for receiving the output and interrupting current in the vehicular recharging cable when the temperature reaches a predetermined temperature, wherein the predetermined temperature is in a range of about from 80° C. to 150° C.
A method for preventing a vehicular recharging cable plug attached to a cable from overheating during a recharging cycle, comprising the steps of:
- generating a temperature-dependent signal in the plug indicative of the plug temperature;
- directing the signal to a current interrupting device coupled to the recharging cable;
- and
- interrupting the current flowing in the cable when the signal exceeds a predetermined temperature, wherein the predetermined temperature is in a range of about from 80° C. to 150° C.
