Title:
METHOD AND APPARATUS FOR IDENTIFYING WIRELESS POWER RECEIVER
Document Type and Number:
WIPO Patent Application WO/2017/018668
Kind Code:
A1
Abstract:
The present invention relates to a method for identifying a wireless power receiver, and apparatuses therefor. The method for identifying a wireless power receiver in a wireless power transmitter may comprise the steps of: detecting an object in a charging area; calculating the amount of impedance variation according to a change in transmission power when the object is detected; and determining, on the basis of the amount of impedance variation, whether or not the object is a normal receiver. Accordingly, the present invention has the advantage of being able to identify a normal receiver even in situations where the communication connection between the wireless power transmitter and the wireless power receiver is not normal.
