Abstract

A power line communication cable is formed in a spiral shape including a single-stranded PLC signal transmitting line transmitting a PLC signal and a ground line being mutually intercrossed, thereby to enhance signal quality of power line communication.

Claims

1. A power line communication cable for charging an electric vehicle, the power line communication cable comprising:

a PLC signal transmitting line connected to a controller generating a control signal for receiving power; and

a ground line connected to a ground,

wherein the PLC signal transmitting line and the ground line respectively include a single stranded wire, where the PLC signal transmitting line and the ground line are formed in a spiral shape by being mutually intercrossed.

2. The power line communication cable of claim 1, wherein the PLC signal transmitting line is made of a copper material.

3. The power line communication cable of claim 1, wherein the power line communication cable transmits a control signal within a bandwidth of 1.8 MHz to 28 MHz.

4. An electric vehicle charging system supplying electric power to an electric vehicle, the electric vehicle charging system comprising:

a power line supplying electric power required to charge the electric vehicle; and

a PLC line transmitting a signal for controlling charging of the electric vehicle,

wherein the PLC line includes a single-stranded PLC signal transmitting line transmitting a PLC signal and a ground line, where the PLC signal transmitting line and the ground line are formed in a spiral shape by being mutually intercrossed.

5. The electric vehicle charging system of claim 4, wherein the PLC line is made of a copper material.

6. An electric vehicle supplied with electric power from an electric vehicle charging system, the electric vehicle comprising:

a power line port supplied with electric power required to charge the electric vehicle from the electric power charging system; and

a PLC line port receiving a signal for controlling charging of the electric vehicle,

wherein the PLC line port is connected to a power line communication cable formed in a spiral shape including a single-stranded PLC signal transmitting line and a ground line being mutually intercrossed.

7. The electric vehicle of claim 6, wherein the PLC line is made of a copper material.
