METHOD AND APPARATUS FOR DISPLAY OF ALIGMENT TRANSMITTER-RECEIVER WIRELESS CHARGE

摘要

PURPOSE: A method and a device for displaying the alignment of a transmitter and a receiver in a wireless charging system are provided to display a detected position of a first coil on a screen, thereby preventing an error in wireless charging due to an alignment error. CONSTITUTION: A first coil(13) is installed in a wireless charging pad(2). A second coil(21) is installed in a smart phone. Multiple sensing coils are installed around the second coil. A program module(130) for displaying wireless charging alignment is installed in the smart phone by downloading an application to the smart phone. The program module detects the position of the first coil corresponding to the configured position of the multiple sensing coils by detecting the strength of transmission power from the first coil through the multiple sensing coils and thus displays a detected position of the first coil and the position of the second coil depending to the multiple sensing coils.
