Abstract

The present invention relates to a charging control apparatus and a control method therefor. A charging control apparatus according to an embodiment of the present invention comprises: a communication unit which performs wireless communication with at least one communication device including a vehicle; a charging connector electrically connected to a charging inlet provided in the vehicle; a locking unit which is disposed in the charging connector, so as to perform or release locking between the charging connector and the charging inlet; a control unit which checks whether the ID of the vehicle, received by the communication unit, is included in a pre-stored authentication information list, in response to an electrical connection between the charging connector and the charging inlet, and when the ID of the vehicle is included in the pre-stored authentication information list, determines whether to release the locking between the charging connector and the charging inlet, depending on the location of a previously authenticated portable device, and controls the locking unit according to the determination.

First claim

The invention claimed is:

1. A charging control apparatus comprising:
a communication device for wired or wireless communication between the charging control apparatus and a vehicle or between the charging control apparatus and a portable device;
a charging connector electrically connected to a charging inlet provided in the vehicle;
a locking device provided in the charging connector to lock or unlock the charging connector and the charging inlet; and
a controller for checking whether an ID of the vehicle received by the communication device is included in a pre-stored authentication information list in response to electrical connection between the charging connector and the charging inlet, determining whether the charging connector and the charging inlet are unlocked according to a position of a pre-authenticated portable device when the ID of the vehicle is included in the pre-stored authentication information list, and controlling the locking device according to the determination.

2. The charging control apparatus according to claim 1 , wherein the controller determines whether the charging connector and the charging inlet are unlocked according to the position of the portable device, when the ID of the portable device received by the communication device is included in the authentication information list.

3. The charging control apparatus according to claim 1 , wherein the controller determines whether the portable device is located within a predetermined distance from the charging control apparatus, based on a signal intensity of a wireless signal received from the portable device by the communication device.

4. The charging control apparatus according to claim 1 , wherein the controller determines whether the portable device is located within a predetermined distance from the charging control apparatus based on GPS coordinates of the portable device received from the portable device.

5. The charging control apparatus according to claim 1 , wherein the controller controls the locking device to lock the charging connector and the charging inlet, when the portable device is located beyond a predetermined distance from the charging control apparatus.

6. The charging control apparatus according to claim 1 , wherein the controller controls the locking device to unlock the charging connector and the charging inlet, when the portable device is located within a predetermined distance from the charging control apparatus.

7. The charging control apparatus according to claim 5 , further comprising at least one of a fingerprint scanner, a barcode/QR code scanner, a touch sensor, a microphone, a keypad and a camera.

8. The charging control apparatus according to claim 7 , further comprising a display unit for displaying information,
wherein the controller controls the display unit to display a screen for requesting to input at least one piece of user authentication information included in the authentication information, when the ID of the vehicle is not included in the authentication information list.

9. The charging control apparatus according to claim 8 , wherein the controller determines whether the charging connector and the charging inlet are unlocked according to the position of the portable device, when the user authentication information is included in the authentication information list.

10. The charging control apparatus according to claim 7 , wherein the controller controls the communication device to request at least one piece of user authentication information included in the authentication information list from the portable device, when the ID of the vehicle is not included in the authentication information list.

11. The charging control apparatus according to claim 10 , wherein the controller determines whether the charging connector and the charging inlet are unlocked according to the position of the portable device, when the user authentication information transmitted from the portable device and received by the communication device in response to the request is included in the authentication information list.

12. The charging control apparatus according to claim 8 , wherein the user authentication information includes at least one of a fingerprint, a barcode, a QR code, voice, a password and an ID of an NFC tag.

13. The charging control apparatus according to claim 9 , wherein the controller performs predetermined operation when the received user authentication information is not included in the authentication information list.

14. The charging control apparatus according to claim 13 , wherein the operation includes (i) warning message output, (ii) electrical disconnection between the charging connector and a power supply and (ii) transmission of a notification to the portable device, and
wherein the notification includes at least one of (i) the ID of the vehicle, (ii) an image received from the camera, (iii) a position of the charging control apparatus and (iv) CCTV information within a predetermined distance from the position of the charging control apparatus.

15. The charging control apparatus according to claim 5 , further comprising an alarm sensor for detecting external force applied to the charging control apparatus,
wherein the controller performs predetermined operation when the external force exceeds a predetermined threshold in a state in which the charging connector and the charging inlet are locked by the locking device.

16. The charging control apparatus according to claim 15 ,
wherein the operation includes (i) warning message output, (ii) electrical disconnection between the charging connector and a power supply and (ii) transmission of a notification to the portable device, and
wherein the notification includes at least one of (i) a time when the external force is sensed, (ii) an image received from the camera and (iii) CCTV information within a predetermined distance from the position of the charging control apparatus.

17. The charging control apparatus according to claim 5 , wherein the controller unlocks the charging connector and the charging inlet based on a command received from the portable device by the communication device, in a state of locking the charging connector and the charging inlet.

18. The charging control apparatus according to claim 8 , wherein the controller controls the display unit to display information related to at least one of the vehicle and the charging control apparatus.

19. The charging control apparatus according to claim 7 , wherein, when a request for use is received from another person, the controller controls the communication device to transmit, to the portable device, information indicating that a request for use has been received.

20. The charging control apparatus according to claim 1 , further comprising:
a plug connected to a power supply for supplying electric energy; and
a switching unit for electrically connecting or disconnecting the charging connector to or from the power supply according to a command received from the controller.
