Abstract

A wireless power transmission device may include a power transmitting module installed outside a vehicle for transmitting power, a power receiving module installed on the vehicle for receiving power from the power transmitting module, and a user interface module configured to control a position of the vehicle and the power transmitting and receiving modules so as to transmit power from the power transmitting module to the power receiving module.

Claims

1. A wireless power transmission device, the device comprising:

a power receiving module installed on the vehicle for receiving power from the power transmitting module; and

a user interface module configured to control a position of the vehicle and the power transmitting and receiving modules so as to transmit power from the power transmitting module to the power receiving module.

2. The device of claim 1, wherein information transmitted from the power receiving module to the user interface module comprises state information of the power receiving module and charging-related state information.

3. The device of claim 1, wherein information transmitted from the user interface module to the power receiving module comprises state information of the user interface module, a charging-related command, operation-related information of a matching assistance module, and charging-related setting information.

4. The device of claim 1, wherein the user interface module displays a position of a transmitting coil connected to the power transmitting module for transmitting power and a position of a receiving coil connected to the power receiving module for receiving power, and guides a movement path of the vehicle so as to allow a user to drive the vehicle and match the transmitting coil with the receiving coil.

5. The device of claim 1, wherein the user interface module provides an initial screen through which charging by wireless power transmission is selected and an execution screen through which the wireless power transmission is executed.

6. The device of claim 1, wherein the user interface module is a navigation device for a vehicle.

7. The device of claim 1, further comprising a matching assistance module configured to move the vehicle using position information of a transmitting coil connected to the power transmitting module for transmitting power and position information of a receiving coil connected to the power receiving module for receiving power, so as to match the transmitting coil with the receiving coil.

8. The device of claim 7, wherein information transmitted from the power receiving module to the matching assistance module comprises state information of the power receiving module, charging progression state information, vehicle position-related information, and vehicle movement-related check information.

9. The device of claim 7, wherein information transmitted from the matching assistance module to the power receiving module comprises state information of the matching assistance module, charging progression state information, vehicle position-related command and information, and vehicle movement progression state-related information.

10. The device of claim 7, wherein the matching assistance module automatically moves the vehicle to match a position of the transmitting coil with a position of the receiving coil.

11. The device of claim 7, wherein the matching assistance module is a PAS (Parking Assistance System).

12. The device of claim 1, further comprising a display unit for displaying a charging progression state by the wireless power transmission device, wherein the display unit is a cluster.

13. The device of claim 12, wherein information transmitted from the power receiving module to the display unit comprises charging progression state information and state information of the power receiving and transmitting modules.

14. The device of claim 1, wherein:

information transmitted from the power transmitting module to the power receiving module comprises communication state information of the power transmitting module, a vehicle information-related command of the power transmitting module, charging-related state information, a charging-related command, a Battery Management System (BMS) information-related command, a power receiving module information-related command, and information of the power transmitting module; and

information transmitted from the power receiving module to the power transmitting module comprises communication state information of the power receiving module, a vehicle information-related response of the power receiving module, charging-related state information, BMS control-related information, power receiving module output-related information, and vehicle and ID-related information.

15. A method for controlling a wireless power transmission device, the method comprising:

performing a charging request input in which a user interface module receives a charging request for a vehicle;

performing a coil matching in which the vehicle is moved using position information of a transmitting coil installed outside of the vehicle and position information of a receiving coil installed on the vehicle so as to match the transmitting coil with the receiving coil;

performing a charging start in which the user interface module receives a charging start request for the vehicle; and

performing a charging finish in which the charging of the vehicle is finished.

16. The method of claim 15, wherein, in the performing of the coil matching, a matching assistance module moves the vehicle using the position information of the transmitting coil and the position information of the receiving coil, so as to match the transmitting coil with the receiving coil, or the user interface module displays a position of the transmitting coil and a position of the receiving coil and guides a movement path of the vehicle equipped with the receiving coil, so as to match the transmitting coil with the receiving coil.

17. The method of claim 16, wherein, in the performing coil matching, the position of the transmitting coil is automatically input by the matching assistance module or is manually input by the user interface module.

18. The method of claim 16, wherein the performing coil matching comprises:

performing a power receiving module state confirmation in which the matching assistance module receives state information of a power receiving module from the power receiving module;

performing a vehicle position confirmation in which the matching assistance module receives a position of the vehicle from the power receiving module;

performing a vehicle movement in which the vehicle is moved;

performing a matching position determination in which the matching assistance module receives a position of the moving vehicle from the power receiving module so as to determine whether the vehicle is at a position at which the transmitting coil is matched with the receiving coil; and

performing a matching completion in which, when the vehicle is at the position at which the transmitting coil is matched with the receiving coil, the movement of the vehicle is stopped.

19. The method of claim 18, wherein, in the performing of the matching position determination, when the vehicle is not at the position at which the transmitting coil is matched with the receiving coil, the performing of the vehicle movement is performed again.

20. The method of claim 15, further comprising performing a charging power setting, in which the user interface module receives charging power or charging time for the vehicle, before the performing the charging start, wherein in the performing of the charging finish, the user interface module receives a charging finish request for the vehicle.
