Wireless energy receiving apparatus and method, and wireless energy transmitting apparatus
First Claim
1. A wireless energy receiving apparatus in a terminal configured to wirelessly receive energy through mutual resonance between a resonator of an energy supply apparatus configured to supply the energy and a resonator of the terminal, the wireless energy receiving apparatus comprising:
- an energy measuring unit configured to measure an amount of energy stored in the terminal; and
a control unit configured to change a state of the resonator of the terminal from a non- resonant state to a resonant state by comparing the measured amount of energy with a predetermined threshold,wherein the predetermined threshold is determined based on a frequency that the terminal comes into contact with the energy supply apparatus.
