FIG. 4 is a flowchart illustrating a wireless charging communication method according to an exemplary embodiment of the present invention. And illustrates the provided wireless power. 3 illustrates in detail the operation of thesecond control unit 260 provided in thefirst control unit 170 and thepower receiver RX 200 provided in thepower transmitter TX 100. The first control unit 170 (A), and the operating portion of thesecond control unit 260 is divided into (b).

우선, 전력 송신기(100)는 제1 안테나(130)에 낮은 파워(P1, 도 4 참조)를 갖는 펄스를 미리 정해진 시간 단위(A, 도 4 참조)마다 주기적으로 공급하면서, 상기 제1 안테나(130)에 걸리는 부하(load)를 모니터링(monitoring)한다.First, thepower transmitter 100 periodically supplies a pulse having a low power (P1, see Fig. 4) to thefirst antenna 130 for every predetermined time unit A (see Fig. 4) 130 of the vehicle.

이 과정에서, 전력 송신기(100)가 커버하는 무선 충전 영역 내에 전력 수신기(RX, 200)가 위치하게 되면, 전력 수신기(RX, 200)에 구비된 상기 제2 안테나(210)는 상기 제1 안테나(130)에 의해 발생한 RF 필드에서 발생되는 전자기 에너지를 흡수하게 된다(S111 단계).In this process, when the power receiver (RX, 200) is located in the wireless charging area covered by thepower transmitter 100, thesecond antenna 210 provided in the power receiver (RX, 200) And absorbs electromagnetic energy generated in the RF field generated by the antenna 130 (step S111).

이에 따라, 상기 전력 송신기(100)에서 제공하는 부하에 변화가 발생하게 되며, 상기 전력 송신기(100)의 충전 가능 영역 내에 충전하려는 물체(즉, 상기 제1 전력 수신기(200))가 진입한 것으로 감지한다(S112 단계). 상기 제1 전력 수신기(200)가 감지되면, 상기 전력 송신기(100)의 제1 제어부(170)는 기설정된 제1 전력 레벨(P2, 도 4 참조)로 송신 전력이 증가 되도록 제어하여, 상기 제1 전력 수신기(200)에 통신 가능한 정도의 전력(P2, 도 4 참조)을 공급한다. 본 발명의 일 실시예에서, 상기 제1 제어부(170)는, 불필요한 전력 소모를 피하기 위해, 상기 제1 전력 수신기(200)가 감지된 이후에 상기 기설정된 제1 전력 레벨(P2)로 송신 전력을 증가시키는 것으로 예시하고 있으나, 상기 제1 제어부(170)는 상기 모니터링 단계에서부터 제1 전력 레벨로 전력(P2)을 송신할 수도 있다.Accordingly, when the load provided by thepower transmitter 100 changes and an object to be charged (that is, the first power receiver 200) enters the chargeable region of the power transmitter 100 (Step S112). When thefirst power receiver 200 is detected, thefirst controller 170 of thepower transmitter 100 controls the transmission power to increase to a predetermined first power level P2 (see FIG. 4) 1 power to the power receiver 200 (P2 in Fig. 4). In an embodiment of the present invention, thefirst control unit 170 may control the transmission power of the first power level P2 to the predetermined first power level P2 after thefirst power receiver 200 is sensed to avoid unnecessary power consumption. However, thefirst controller 170 may transmit the power P2 from the monitoring step to the first power level.
