Wireless energy receiving apparatus and method, and wireless energy transmitting apparatus

摘要

An apparatus and a method for wirelessly receiving and transmitting energy are provided. 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, includes an energy measuring unit configured to measure an amount of energy stored in the terminal. The wireless energy receiving apparatus further includes a control unit configured to change a state of the resonator of the terminal from a non-resonant state to a resonant state when the measured amount of energy is less than or equal to a predetermined threshold.

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.
