Wireless power receiver for receiving power from a wireless power transmitter using a power signal through a resonance frequency band
First Claim
1. A wireless power reception method of a wireless power receiver for receiving power from a wireless power transmitter using a power signal through a resonance frequency band, the wireless power reception method comprising:
- receiving a connection signal for detecting and identifying the wireless power receiver from the wireless power transmitter;
transmitting a response signal in response to the connection signal to the wireless power transmitter through a specific frequency band;
receiving state information of the wireless power transmitter from the wireless power transmitter through the specific frequency band, wherein the state information comprises an available amount of power of the wireless power transmitter;
transmitting specific state information to the wireless power transmitter through the specific frequency band, wherein the specific state information comprises a demanded amount of power of the wireless power receiver, and wherein the demanded amount of power is adjusted by the wireless power receiver within the available amount of power of the wireless power transmitter; and
receiving the power from the wireless power transmitter according to the specific state information through the resonance frequency band being a resonance-coupled frequency between the wireless power transmitter and the wireless power receiver and being different than the specific frequency band.
