Abstract
Provided is an energy charging apparatus including a transponder configured to transmit and receive radio energy, and a resonator configured to transmit the radio energy transmitted from the transponder to at least one external device and transmit the radio energy received from the at least one external device to the transponder, wherein each of the transponder and the resonator is provided in a form of a single module.
Claims15
An energy charging apparatus comprising:
- a transponder configured to transmit and receive energy;
- and
- a resonator configured to transmit the energy transmitted from the transponder to at least one external device and transmit the energy received from the at least one external device to the transponder,
- wherein the transponder comprises:
- a transmitter configured to transmit the energy to the resonator;
- a receiver configured to receive the energy from the resonator;
- and
- a transponder switch configured to selectively connect the resonator with one of the transmitter and the receiver;
- wherein the transmitter comprises:
- a first transmitter configured to transmit the energy with a first frequency to the resonator;
- the resonator configured to transmit the energy with the first frequency to the at least one external device based on a magnetic resonance scheme;
- a second transmitter configured to transmit the energy with a second frequency lower than the first frequency to the resonator;
- the resonator configured to transmit the energy with the second frequency to the at least one external device based on a magnetic induction scheme;
- and
- a mode changing switch configured to selectively connect the transponder with one of the first transmitter and the second transmitter.
