호스트부(100)는 휴대기기 측에 배터리(500) 상태정보를 요청하여, 배터리(500)의 상태를 확인한다(S14). 호스트부(100)가 배터리(500)의 상태정보를 요청하면, 휴대기기 측의 마이컴(420)은 배터리 관리시스템(410)으로부터 배터리(500)의 상태정보를 전달받아 데이터신호 처리부(330) 및 무선통신부(320)를 통해 호스트부(100)에 배터리(500) 상태정보를 송신한다. 이에, 호스트부(100)는 배터리(500)의 잔량 등을 포함하는 배터리(500) 상태정보를 수신하여 확인할 수 있다.The host unit 100 checks the state of the battery 500 by requesting the state of the battery 500 from the portable device (S14). When the host unit 100 requests the state information of the battery 500, the microcomputer 420 of the mobile device receives the state information of the battery 500 from the battery management system 410 and the data signal processing unit 330 and the data signal processor 330. The battery 500 status information is transmitted to the host unit 100 through the wireless communication unit 320. Accordingly, the host unit 100 may receive and confirm the battery 500 state information including the remaining amount of the battery 500.

호스트부(100)의 판단결과 배터리(500) 잔량이 충전시작 기준값보다 작은 것으로 판단되면, 호스트부(100)는 1차코일(110)을 통해 충전신호를 송신한다(S16).If the host unit 100 determines that the remaining amount of the battery 500 is smaller than the charging start reference value, the host unit 100 transmits a charging signal through the primary coil 110 (S16).

휴대기기는 2차코일(210)을 통해 충전신호를 수신하여 배터리(500)를 충전한다(S18). 휴대기기에 충전신호가 수신되면 2차코일(210)에 전류가 여기되어 충전부(200)로 전달되며, 배터리 관리시스템(410)은 충전부(200)에서 공급하는 충전전원을 배터리(500)에 충전한다.The mobile device receives the charging signal through the secondary coil 210 to charge the battery 500 (S18). When the charging signal is received by the mobile device, the current is excited by the secondary coil 210 and transferred to the charging unit 200. The battery management system 410 charges the battery 500 with the charging power supplied from the charging unit 200. do.

이상 설명한 바와 같이, 본 실시예에 따른 무선 충전시스템은 호스트부(100)가 휴대기기의 배터리(500) 상태를 직접 확인하여, 충전이 필요한 경우 자동으로 충전신호를 공급하여 배터리(500)가 충전되도록 할 수 있다.As described above, in the wireless charging system according to the present embodiment, the host unit 100 directly checks the state of the battery 500 of the mobile device, and automatically supplies a charging signal when charging is required so that the battery 500 is charged. You can do that.

도 3은 본 발명의 제2실시예에 따른 무선 충전시스템의 제어흐름도이다.3 is a control flowchart of a wireless charging system according to a second embodiment of the present invention.

호스트부(100)에서 충전신호를 송신하여 휴대기기의 배터리(500)를 충전하는 중에(S30), 휴대기기와 호스트부(100) 간에 통신기능이 개시된다(S32). 충전중에 통신기능이 개시되는 상황으로는, 사용자가 호스트의 UI(140)를 조작하여 휴대기기의 데이터를 확인하고자 하거나, 휴대기기가 휴대폰인 경우 휴대기기에 전화가 수신되는 경우 등, 다양한 상황들을 예측할 수 있다.While charging the battery 500 of the portable device by transmitting a charging signal from the host unit 100 (S30), a communication function is started between the portable device and the host unit 100 (S32). In a situation in which a communication function is initiated while charging, various situations such as a user trying to check data of a mobile device by operating the UI 140 of the host or when a call is received by the mobile device when the mobile device is a mobile phone It can be predicted.

충전중 데이터 통신기능이 개시되면, 호스트는 충전신호 및 데이터신호를 동시에 송신한다(S34). 여기서, 충전신호는 MHz 대역의 신호이고 데이터신호는 상대적으로 고주파 대역인 GHz 대역 신호를 이용함으로써, 충전신호 및 데이터신호를 동시 송신하는 것이 가능하다.When the data communication function is started during charging, the host simultaneously transmits a charging signal and a data signal (S34). Here, the charging signal is a signal of the MHz band and the data signal is a high frequency band GHz band signal, it is possible to transmit the charging signal and the data signal at the same time.

휴대기기는 수신된 충전신호 및 데이터신호를 처리하여, 배터리(500)가 충전되도록 하는 한편, 데이터신호에 따른 기능을 수행할 수 있다(S36). 예컨대, 휴대기기는 충전기능을 수행함과 동시에, 휴대기기 내에 저장된 데이터를 호스트부(100)에 전달할 수 있다. 또한, 휴대기기가 휴대폰인 경우, 송수신되는 전화 음성신호를 휴대기기와 호스트부(100) 간에 송수신 함으로써, 호스트부(100)가 제어하는 핸즈프리장치(미도시)를 이용할 수 있다.The portable device may process the received charging signal and the data signal to allow the battery 500 to be charged and perform a function according to the data signal (S36). For example, the mobile device may perform a charging function and transfer data stored in the mobile device to the host unit 100. In addition, when the mobile device is a mobile phone, a hands-free device (not shown) controlled by the host unit 100 may be used by transmitting and receiving a telephone voice signal transmitted and received between the mobile device and the host unit 100.
