not connect the first proximity detection pin and the second proximity detection pin.

2. The charging cable of claim 1 , wherein:
the first connector further comprises a first control pilot pin,
the second connector further comprises a second control pilot pin, and
the cable is configured to connect the first control pilot pin and the second control pilot pin.

3. The charging cable of claim 1 , wherein:
the first connector further comprises:
a first ground pin electrically connected to the first proximity detection pin; and
a first resistance located between the first ground pin and the first proximity detection pin, and

the second connector further comprises:
a second ground pin electrically connected to the second proximity detection pin; and
a second resistance located between the second ground pin and the second proximity detection pin.

4. The charging cable of claim 3 , wherein the cable is configured to not connect the first resistance and the second resistance.

5. The charging cable of claim 3 , wherein the charging cable further comprises:
the first connector further comprising:
a first switch element connected in parallel with the first resistance and implemented as a normally-closed switch element that operates in response to an operation of a switch provided outside the first connector, and

the second connector further comprising:
a second switch element connected in parallel with the first resistance and implemented as a normally-closed switch element that operates in response to an operation of a switch provided outside the second connector.

6. A charging cable comprising:
a first connector comprising a first proximity detection pin and a first power pin;
a second connector comprising a second proximity detection pin and a second power pin;
a cable configured to:
electrically connect the first power pin and the second power pin to form a power supply path; and
not connect the first proximity detection pin and the second proximity detection pin; and

a communication controller configured to control supply of charging power through the power supply path corresponding to a connection state of the first connector and the second connector to the vehicle.

7. The charging cable of claim 6 , wherein the communication controller further comprises:
a controller configured to:
determine a connection state between the first connector and a first vehicle based on a first detection signal of the first proximity detection pin; and
determine a connection state between the second connector and a second vehicle based on a second detection signal of the second proximity detection pin.

8. The charging cable of claim 7 , wherein the controller is configured to:
determine a connection state between the first connector and the first vehicle by comparing a voltage of the first detection signal with a predetermined proximity detection voltage standard; and
determine a connection state of the second connector and the second vehicle by comparing a voltage of the second detection signal with the predetermined proximity detection voltage standard.

9. The charging cable of claim 7 , wherein the controller is configured to:
generate a power transmission signal for controlling a supply of charging power through the power supply path when the first connector and the first vehicle are determined to be connected, and the second connector and the second vehicle are determined to be connected.

10. The charging cable of claim 9 , wherein:
the first connector further comprises a first control pilot pin,
the second connector further comprises a second control pilot pin, and
the communication controller further comprises:
a communicator configured to:
receive a charge state signal for a battery charge state of the first vehicle and the second vehicle through the first control pilot pin and the second control pilot pin; and
transmit the power transmission signal to the first vehicle and the second vehicle through the first control pilot pin and the second control pilot pin.

11. The charging cable of claim 10 , wherein the communicator is further configured to:
transceive a signal with the first vehicle and the second vehicle using a power line communication.

12. The charging cable of claim 6 , wherein:
the first connector further comprises:
a first ground pin electrically connected to the first proximity detection pin; and
a first resistance located between the first ground pin and the first proximity detection pin, and

the second connector further comprises:
a second ground pin electrically connected to the second proximity detection pin; and
a second resistance located between the second ground pin and the second proximity detection pin.

13. The charging cable of claim 12 , wherein the cable is configured to:
not connect the first resistance and the second resistance.

14. The charging cable of claim 13 , wherein the charging cable further comprises:
the first connector further comprising:

the second connector further comprising:
a second switch element connected in parallel with the first resistance and implemented as a normally-closed switch element that operates in response to an operation of a switch provided outside the second connector.

15. A control method of a charging cable comprising:
detecting a first detection signal of a first proximity detection pin and a second detection signal of a second proximity detection pin;
determining a connection state of a first connector and a first vehicle based on the first detection signal, wherein the first connector comprises the first proximity detection pin and a first power pin; and
determining a connection state between a second connector and a second vehicle based on the second detection signal, wherein the second connector comprises the second proximity detection pin a second power pin.

16. The control method of claim 15 , wherein the method further comprises:
determining a connection state between the first connector and the first vehicle by comparing a voltage of the first detection signal with a predetermined proximity detection voltage standard; and
determining a connection state between the second connector and the second vehicle by comparing a voltage of the second detection signal with the predetermined proximity detection voltage standard.

17. The control method of claim 15 , wherein the method further comprises:
