Abstract

A bidirectional wireless charging method includes performing a mode change to a requesting electronic device if charging is necessary, requesting charging from at least one electronic device, receiving status information from the at least one electronic device that has received the charging request, selecting the electronic device based on the status information, and performing charging by receiving power supplied from the selected at least one electronic device.

Description

technical field [0001] The present invention relates generally to wireless charging of electronic devices, and more particularly to methods and apparatus for performing wireless charging between electronic devices using near field communication. Background technique [0002] Mobile terminals such as cellular phones, PDAs (Personal Digital Assistants), etc. are powered by rechargeable batteries, and to charge such batteries, power is supplied to the batteries of the mobile terminals using an independent charging device. Typically, the charging device and the battery are provided with separate contact terminals, wherein the charging device and the battery are electrically connected via the contact terminals. [0003] However, one problem with such contact-type charging systems is that the outwardly protruding contact terminals are susceptible to contamination by foreign matter or even moisture, which prevents proper battery charging. [0004] In order to solve these problems,...
