Abstract

A wireless power transmission device may include a power transmitter configured to transmit power for charging, a power receiver configured to perform a communication protocol with the power transmitter and receive the power transmitted from the power transmitter, and an interface configured to exchange information for performing the charging based on the power receiver and the communication protocol and control power transmission from the power transmitter to the power receiver depending on the exchange of the information.

Claims

1. A wireless power transmission device, comprising:

a power transmitter configured to transmit power for charging;

a power receiver configured to perform a communication protocol with the power transmitter and receive the power transmitted from the power transmitter; and

an interface configured to exchange information for performing the charging based on the power receiver and the communication protocol and control power transmission from the power transmitter to the power receiver depending on the exchange of the information.

2. The wireless power transmission device of claim 1, wherein the information transmitted from the power receiver to the interface includes at least one of power receiver state information, charging related progress information, fault occurrence situation information, charging quantity display information, and charging remained time information.

3. The wireless power transmission device of claim 1, wherein the information transmitted from the interface to the power receiver includes at least one of terminal state information, charging start and finish information, charging time setting information, charging power setting information, and position correction start information and position correction finish information of a matching assistant.

4. The wireless power transmission device of claim 1, wherein the interface is a communication terminal wirelessly communicating with the power receiver.

5. The wireless power transmission device of claim 1, wherein the interface displays a wireless power transmission progress of a vehicle, displays a charging quantity, displays charging remained time, or displays no charging situation.

6. The wireless power transmission device of claim 1, wherein the interface receives at least one of charging start, charging stop, charging finish, charging power, and charging time.

7. The wireless power transmission device of claim 1, wherein the power transmitter includes a transmitting coil transmitting power and the power receiver includes a receiving coil receiving power transmitted from the transmitting coil.

8. The wireless power transmission device of claim 7, further comprising:

a matching assistant configured to drive the vehicle to match the transmitting coil with the receiving coil using position information of the transmitting coil and the receiving coil.

9. The wireless power transmission device of claim 8, wherein the information transmitted from the power receiver to the matching assistant includes at least one of state information of the power receiver, charging progress state information, vehicle position information, vehicle moving coordinate information, and vehicle moving check-in information.

10. The wireless power transmission device of claim 8, wherein the information transmitted from the matching assistant to the power receiver includes at least one of state information of the matching assistant, charging progress state information, vehicle position information, and vehicle moving progress state information.

11. The wireless power transmission device of claim 7, wherein the matching assistant is a Parking Assistant System (PAS).

12. The wireless power transmission device of claim 1, further comprising:
