Wireless power charging method and apparatus
First Claim
1. A wireless charging method of a first electronic device, comprising:
- searching for at least one second electronic device, wherein the at least one second electronic device is chargeable;
obtain status information related to a power state of the at least one second electronic device and the first electronic device;
identifying whether the first electronic device is a power supply electronic device or a power demand electronic device, based on the obtained status information;
receiving power, from the at least one second electronic device, based on a providable power amount determined by the at least one second electronic device, if the first electronic device is identified as the power demand electronic device;
repeatedly receiving a charging information message from the at least one second electronic device while receiving the determined providable power amount;
if the charging information message is not received from the at least one second electronic device within a predetermined time, identifying that the wireless charging is interrupted; and
if the charging information message is received from the at least one second electronic device within the predetermined time, transmitting a charging information response message,wherein the charging information message includes information indicating an amount of power applied by the second electronic device.
