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, comprising:

a power receiving module installed on a vehicle and configured to receive power from a power transmitting module;

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

a display unit configured to display a charging progression state of the wireless power transmission device,

wherein information transmitted from the power receiving module to the display unit comprises information about the charging progression state and state information of the power receiving module and the power transmitting module.

2. The device of claim 1, wherein information transmitted from the power receiving module to the user interface module comprises state information about 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 is further configured to display a position of a transmitting coil connected to the power transmitting module and a position of a receiving coil connected to the power receiving module, and guide a movement path of the vehicle so as to allow a user to drive the vehicle to match a position of the transmitting coil with a position of the receiving coil.

5. The device of claim 1, wherein the user interface module is further configured to provide 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 comprises a navigation device for the 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 and position information of a receiving coil connected to the power receiving module, to match a position of the transmitting coil with a position of 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 about 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 commands and information, and vehicle movement progression state-related information.

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

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

12. The device of claim 1, wherein the display unit comprises a cluster.

13. 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 commands, a power receiving module information-related command, and information of the power transmitting modulo;

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, other charging-related state information, BMS control-related information, power receiving module output-related information, and vehicle and ID-related information.

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

receiving, from a user interface module, a charging request for a vehicle;

moving the vehicle 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 a position of the transmitting coil with a position of the receiving coil;

charging the vehicle, in response to receiving a charging start request for the vehicle;

transmitting, from a power receiving module to a display unit, information about a charging progression state of the wireless power transmission device and state information of the power receiving module and a power transmitting module; and

displaying, by the display unit, the charging progression state of the wireless power transmission device,

wherein the power transmission module is connected to the transmitting coil and the power receiving module is connected to the receiving coil.

15. The method of claim 14, wherein the moving of the vehicle comprises moving the vehicle autonomously or displaying, by the user interface module, the position of the transmitting coil and the position of the receiving coil, and guiding a movement path of the vehicle to match the position of the transmitting coil with the position of the receiving coil.

16. The method of claim 15, wherein the moving of the vehicle comprises automatically inputting the position of the transmitting coil by the matching assistance module, or receiving input from the user interface module.

17. The method of claim 15, wherein the moving of the vehicle comprises

receiving, by the matching assistance module, from the power receiving module, state information of the power receiving module,

moving the vehicle,

receiving, by the matching assistance module, from the power receiving module, a position of the vehicle so as to determine whether the position of the transmitting coil is matched with the position of the receiving coil, and

stopping movement of the vehicle, in response to the position of the transmitting coil matching the position of the receiving coil.

18. The method of claim 17, further comprising moving the vehicle again, in response to the position of the transmitting coil not matching with the position of the receiving coil.

19. The method of claim 14, further comprising receiving, by the user interface module, charging power information or charging time information, before the charging of the vehicle, and discontinuing the charging of the vehicle, in response to the user interface module receiving a charging finish request.
