Abstract

Provided is a plug of a grid-side power cable assembly connected to a cable installment type charging control device for charging an electric vehicle (EV) by using power of a grid-side. An exclusive socket detecting part detects whether a socket connected to the plug is an exclusive socket for the plug. A normal operation signal generating part generates a signal notifying whether the exclusive socket is detected. A voltage dividing part outputs a voltage so that an output voltage in a case in which the grid-side assembly is short-circuited is different from that of the grid-side power cable assembly in a case in which the signal is generated.

Claims

1. A plug of a grid-side power cable assembly connected to a cable installment type charging control device for charging an electric vehicle (EV) by using power of a grid-side, the plug comprising:

an exclusive socket detecting part for detecting whether a socket connected to the plug is an exclusive socket for the plug;

a normal operation signal generating part for generating a signal notifying whether the exclusive socket is detected; and

a voltage dividing part for outputting a voltage so that an output voltage in a case in which the grid-side power cable assembly is short-circuited is different from that of the grid-side power cable assembly in a case in which the signal is generated.

2. The plug according to claim 1, further comprising a plug temperature measuring part for measuring a temperature of the plug,

wherein, when the grid-side power cable assembly is short-circuited, the plug temperature measuring part and the grid-side power cable assembly are short-circuited.

3. The plug according to claim 2, wherein the plug temperature measuring part comprises a thermistor resistor.

4. The plug according to claim 1, wherein the normal operation signal generating part comprises a switch having one end that is grounded and turned-on on the basis of whether the exclusive socket is detected, and

the voltage dividing part comprises a resistor connected to the other end of the switch.

5. The plug according to claim 1, wherein the exclusive socket detecting part comprises a magnetic sensor for detecting magnetic fields to detect the exclusive socket on the basis of the detected magnetic fields.

6. The plug according to claim 5, wherein the exclusive socket detecting part detects the exclusive socket on the basis of polarity and intensity of the magnetic fields.

7. A method of operating a plug of a grid-side power cable assembly connected to a cable installment type charging control device for charging an electric vehicle (EV) by using power of a grid-side, the method comprising:

detecting whether a socket connected to the plug is an exclusive socket for the plug;

generating a normal operation signal notifying whether the exclusive socket is detected; and

outputting a voltage so that an output voltage in a case in which the grid-side power cable assembly is short-circuited is different from that of the grid-side power cable assembly in a case in which the signal is generated.

8. The method according to claim 7, further comprising measuring a temperature of the plug through a plug temperature measuring part,

wherein, when the grid-side power cable assembly is short-circuited, the plug temperature measuring part and the grid-side power cable assembly are short-circuited.

9. The method according to claim 8, wherein the plug temperature measuring part comprises a thermistor resistor.

10. The method according to claim 7, wherein the detecting of whether the socket connected to the plug is the exclusive socket for the plug comprises detecting the exclusive socket on the basis of magnetic fields detected by using a magnetic sensor for detecting the magnetic fields.

11. The method according to claim 10, wherein the detecting of the exclusive socket on the basis of the detected magnetic fields comprises detecting the exclusive socket on the basis of polarity and intensity of the magnetic fields.
