Title:
DEVICE AND METHOD FOR SUPPORTING HETEROGENEOUS COMMUNICATION IN WIRELESS POWER TRANSFER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/153586
Kind Code:
A1
Abstract:
The present specification relates to a device and method for supporting heterogeneous communication in a wireless power transfer system. The present specification discloses a wireless power reception device comprising: a power pickup circuit configured to receive, from a wireless power transfer device, wireless power generated on the basis of magnetic coupling in a power transfer phase; and a communication and control circuit configured to transmit, to the wireless power transfer device, a first random address packet including a random address of the wireless power reception device or receive, from the wireless power transfer device, a second random address packet including a random address of the wireless power transfer device via in-band communication. By performing a handover using a random address, cross reference can be prevented and security can be enhanced, and thus a BLE connection in a wireless charging system can be more safely performed.
