Abstract
A method of a charging apparatus for controlling wireless charging is provided. The method includes detecting an electronic device, determining a charging method corresponding to the detected electronic device, and wirelessly charging the electronic device by selecting a coil corresponding to the determined charging method.
Claims16
A method for controlling wireless charging by a charging apparatus, the method comprising:
- outputting, through a plurality of coils for a magnetic induction technique, a first detection power for identifying a charging method of a first electronic device;
- outputting, through at least one coil for a magnetic resonance technique, a second detection power for identifying a charging method of the first electronic device;
- identifying whether a response signal corresponding to the first detection power or the second detection power is received based on an in-band communication through the plurality of coils for the magnetic induction technique or an out-of-band communication through a communication circuit configured to perform a BLE communication;
- in response to identifying that a first response signal by the first electronic device is received, based on the in-band communication,
- transmitting a first charging power that is greater than the first detection power output through the plurality of coils for the magnetic induction technique for charging the first electronic device;
- while transmitting the first charging power for charging the first electronic device through the plurality of coils for the magnetic induction technique, outputting, through the at least one coil for the magnetic resonance technique, the second detection power for identifying a charging method of a second electronic device different from the first electronic device;
- and
- in response to identifying that a second response signal from the second electronic device is received based on the out-of-band communication through the communication circuit while transmitting the first charging power for charging the first electronic device through the plurality of coils for the magnetic induction technique,
- transmitting a second charging power for charging the second electronic device through the at least one coil for the magnetic resonance technique while transmitting the first charging power for charging the first electronic device through the plurality of coils for the magnetic induction technique.
