Abstract
The present disclosure concerns a wireless power transmission system, comprising a primary unit including a primary pad for wireless power transmission and a primary wireless communication unit; a secondary unit including a secondary pad for wireless power reception and a secondary wireless communication unit; and a control unit; wherein the primary pad and the secondary pad are configured to wirelessly transfer power via inductive coupling, wherein the primary and secondary wireless communication units are configured to transmit and receive a communication signal, and wherein the control unit is configured to detect a relative position of the primary wireless communication unit and the secondary wireless communication unit using the communication signal.
Claims20
A wireless power transmission device for inductively transferring power with another wireless power transmission device, comprising:
- a power transfer unit having one or more coils, configured to inductively transfer power;
- a main communication antenna, configured to transmit and receive a communication signal to and from the other wireless power transmission device;
- two or more auxiliary sensing antennas, configured to receive the communication signal from the other wireless power transmission device;
- a control unit, configured to detect a relative position of the wireless power transmission device with the other wireless power transmission device according to the communication signal received by the two or more auxiliary sensing antennas and configured to control data transfer of the main communication antenna and power transfer of the power transfer unit according to the relative position.
A wireless power transmission system, comprising:
- a first wireless power transmission device, comprising a first power transfer unit, a first main antenna configured to transfer a communication signal;
- a second wireless power transmission device, comprising a second power transfer unit, a second main antenna configured to transfer the communication signal and two or more auxiliary sensing antennas configured to receive the communication signal;
- a control unit, configured to perform data transfer using the communication signal transmitted and/or received by the first main antenna and the second main antenna, and configured to detect relative position of the first and second wireless power transmission devices using the communication signal received by the two or more auxiliary sensing antennas;
- wherein the control unit is further configured to initiate the power transfer and the data transfer between the first and second wireless power transmission devices according to the relative position of the first and second wireless power transmission devices.
