First Claim
1. An electronic device, comprising:
- a battery;
a power receiving circuit comprising a spiral coil configured to wirelessly receive a first energy or a second energy from a wireless power transmitter, the first energy being used to perform a communication function, and the second energy being used to charge the battery, wherein the second energy is greater than the first energy;
a controller;
a voltage generating circuit configured to generate a voltage for activating the controller from the first energy, or to generate a voltage for charging the battery from the second energy; and
a communication circuit configured to perform the communication function based on a control of the controller,wherein the controller is configured to transmit a signal including information for an identification of the electronic device to the wireless power transmitter through the communication circuit.
