Abstract

A electric vehicle cable mounting system includes a driving unit including a rotary disc and allowing a charging cable to be released from a side in accordance with a rotation motion of a rotary disc, a guide unit provided behind the driving unit and allowing the driving unit to move in a vertical direction in accordance with a rotation motion of the rotary disc, and a controller controlling the driving unit and the guide unit such that the charging cable is automatically released in an electric vehicle charge mode and is automatically returned in an electric vehicle charge standby mode.

First claim

1 . An electric vehicle charging cable mounting system comprising:
a driving unit including a rotary disc, the driving unit being configured to allow the charging cable to be released from a side in accordance with a rotation motion of the rotary disc; a guide unit positioned behind the driving unit, the guide unit being configured to allow the driving unit to move in a vertical direction in accordance with a rotation motion of the rotary disc; and a controller configured to control the driving unit and the guide unit such that the charging cable is automatically released in an electric vehicle charge mode and is automatically returned in an electric vehicle charge standby mode.

2 . The electric vehicle charging cable mounting system of claim 1 , wherein the controller is configured to calculate a release amount of the charging cable based on a distance between the driving unit and an electric vehicle charging section, and to allow the charging cable to be automatically released in accordance with the calculated release amount of the charging cable.

3 . The electric vehicle charging cable mounting system of claim 1 , further comprising a plurality of guide rollers positioned inside the driving unit, disposed in a circumferential direction in which the charging cable is released, and configured to prevent separation of the charging cable.

4 . The electric vehicle charging cable mounting system of claim 3 , further comprising a disc motor positioned behind the driving unit, the disc motor being configured to supply power such that the rotary disc is rotated;
wherein a rotation speed of the disc motor is adjusted in accordance with a size of guide rollers and a release speed of the charging cable.

5 . The electric vehicle charging cable mounting system of claim 4 , further comprising a guide motor positioned over the guide unit, the guide motor being configured to supply power such that the driving unit is moved in the vertical direction in accordance with a rotation motion of the rotary disc,
wherein a rotation speed of the guide motor is adjusted in accordance with rotation speed of the disc motor and the release speed of the charging cable.

6 . The electric vehicle charging cable mounting system of claim 1 , further comprising a proximity sensor configured to recognize information of the kind of an electric vehicle when the electric vehicle approaches for charging.

7 . The electric vehicle charging cable mounting system of claim 6 , wherein when the proximity sensor recognizes information of the kind of an electric vehicle, the controller allows the charging cable to be automatically released in accordance with release amounts of the charging cable set in advance for the kinds of electric vehicles.

8 . The electric vehicle charging cable mounting system of claim 1 , further comprising a load sensor configured to sense a load that is applied to the driving unit due to weight according to a release amount of the charging cable when the charging cable is released.

9 . The electric vehicle charging cable mounting system of claim 8 , wherein the controller determines whether the load sensed by the load sensor exceeds a reference value, and stops release of the charging cable, depending on the determination result.

10 . The electric vehicle charging cable mounting system of claim 1 , wherein the controller recognizes whether a coupler is separated in the state in which the coupler is mounted such that the charging cable is automatically released in the electric vehicle charge mode.

11 . The electric vehicle charging cable mounting system of claim 1 , wherein the controller recognizes whether a coupler is mounted in the state in which the coupler is separated such that the charging cable is automatically returned in the electric vehicle charge standby mode.

12 . A method of mounting an electric vehicle charging cable including a driving unit having a rotary disc and allowing a charging cable to be released from a side in accordance with a rotation motion of a rotary disc, and a guide unit provided behind the driving unit and allowing the driving unit to move in a vertical direction in accordance with a rotation motion of the rotary disc, the method comprising:
allowing, by a controller, the charging cable to be automatically released in an electric vehicle charge mode by controlling the driving unit and the guide unit; and allowing the charging cable to be automatically returned by the controller in an electric vehicle charge standby mode.

13 . The method of claim 12 , wherein allowing the charging cable to be automatically released includes:
calculating, by the controller, a release amount of the charging cable based on a distance between the driving unit and an electric vehicle charging section; and allowing, by the controller, the charging cable to be automatically released in accordance with the calculated release amount of the charging cable.

14 . The method of claim 12 , wherein allowing the charging cable to be automatically released includes:
recognizing, by a proximity sensor, information of the kind of an electric vehicle when the electric vehicle approaches for charging; and allowing the charging cable to be automatically released in accordance with release amounts of the charging cable set in advance for a plurality of kinds of electric vehicles, when the proximity sensor recognizes information of one of the plurality of kinds of electric vehicles.

15 . The method of claim 12 , further comprising:
sensing, by a load sensor, a load that is applied to the driving unit due to weight according to a release amount of the charging cable when the charging cable is released; and determining whether a load sensed by the load sensor exceeds a reference value, and stopping release of the charging cable, when the load sensed by the load sensor exceeds the reference value.
