무선 충방전 배터리{Wireless Charging and Discharging Battery}[0001] Wireless Charging and Discharging Battery [

본 발명은 스마트폰 충전용 보조베터리의 무선 충전과 무선 방전에 관한 것으로, 보다 상세하게는 보조베터리를 충전하기 위한 무선 충전방법과 보조베터리가 스마트폰을 충전하게 하는 무선 방전 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to wireless charging and wireless discharging of an auxiliary battery for charging a smart phone, and more particularly to a wireless charging method for charging an auxiliary battery and a wireless discharging method for charging the smart phone.

최근 스마트폰은 인터넷 검색 뿐만 아니라 게임,오디오/동영상 재생, 정보처리 및 데이터 저장등 기존의 컴퓨터에서 수행이 가능했던 기능들도 할 수 있게 되었다.In recent years, smartphones have been able to perform functions that could be performed on existing computers such as games, audio / video playback, information processing and data storage as well as Internet search.

이와 같이 스마트폰이 다양한 기능을 수행할 수 있게 됨에 따라 이용자는 일반적으로 하나 이상의 기능을 사용하는 경우가 많으며, 이로 인해 스마트폰의 전력 소모량이 증가하게 되었다.As the smartphone can perform various functions, the user generally uses more than one function in general, and the power consumption of the smartphone is increased.

일반적으로 스마트폰의 전력 충전 방식은 어댑터(adaptor)를 연결하여 충전이 이루어지고 있고 이 방법을 가장 많이 사용하고 있다.Generally, the power charging method of a smart phone is charging by connecting an adapter, and this method is used the most.

하지만 이런 충전 방식은 어댑터를 항상 들고 다녀야 하며, 어댑터에 전원을 공급해줄 콘센트가 없으면 사용하지 못하는 단점이 존재하여 많은 이용자들이 보조베터리를 사용하고 있고, 새로나온 스마트폰들도 배터리가 일체형 이거나 하나만 제공해주는 경우가 많아서 보조베터리 이용자는 증가하고 있다.However, this charging method has the disadvantage that the adapter must be carried all the time, and if there is no outlet to supply power to the adapter, there is a disadvantage that many users use the auxiliary battery, and the new smartphone also has a single battery or only one The number of secondary battery users is increasing.

보조베터리의 충전 방식 역시 어댑터에 연결하여 충전을 하는게 대부분의 방식이다. 그래서 앞서 언급했던 스마트폰의 충전 방식과 같은 문제점이 있다.The charging method of the auxiliary battery is also connected to the adapter in most cases. Therefore, there is a problem such as the charging method of the smartphone mentioned above.

본 발명은 전술한 문제점을 해결하기 위해 창안된 것으로서, 보조베터리를 유선 충전 및 방전은 물론이고 스마트폰 충전용 무선 송신기가 있는 곳에서도 무선 충전 할 수 있고, 무선충전이 가능한 스마트폰에 무선으로 전력을 보낼수 있는 보조베터리 및 그 충방전 방법을 제공하는것을 목적으로 한다. The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an auxiliary battery which can be charged wirelessly even in a place where there is a wireless transmitter for charging a smartphone as well as wire charging and discharging, And an object thereof is to provide an auxiliary battery and a charging / discharging method thereof.

전술한 목적을 달성하기 위한 무선 충방전 보조베터리는 크게 무선충전부와 무선방전부로 구성되어 있다.To achieve the above object, a wireless charging / discharging auxiliary battery includes a wireless charging unit and a wireless discharging unit.

무선충전부는 외부의 무선 충전 송신기로부터 전력을 전달받는 수신코일; 전력을 전달 받기위한 LC 공진을 위한 공진커패시터; 전달 받은 전력을 직류로 바꿔주는 직류전환장치; 직류전환장치에서 온 전압을 보조배터리에 충전하기위해 5V로 맞춰주는 전압변환장치를 포함하는것을 특징으로한다.The wireless charging unit includes a receiving coil for receiving power from an external wireless charging transmitter; A resonance capacitor for LC resonance for receiving electric power; A direct current switching device for converting the received electric power into direct current; And a voltage converting device for adjusting the on-voltage of the direct current converting device to 5V for charging the auxiliary battery.

무선방전부는 보조베터리로에서 받은 전력을 교류로 바꿔주는 교류전환장치; 교류전환장치로 부터 온 전력을 내보내기위한 송신코일; 송신코일과 함께 LC공진을 위한 공진커패시터;를 포함하는것을 특징으로한다. The wireless discharge unit includes an alternating current switching device for converting the electric power received from the auxiliary battery to AC; A transmitting coil for transmitting power from the AC switching device; And a resonance capacitor for LC resonance together with the transmission coil.

본 발명에 따르면 무선충전이 가능한 송신기가 있으면 별도의 어댑터 없이도 보조베터리를 충전 할 수 있고, 무선충전이 가능한 스마트폰을 보조베터리로 충전 할 때 별도에 케이블이 없어도 스마트폰을 충전 할 수 있어 사용자의 스마트폰 배터리 충전의 방식을 다양하게 해줄 수 있다. According to the present invention, if there is a transmitter capable of wireless charging, it is possible to charge the auxiliary battery without a separate adapter, and when charging the smartphone capable of wireless charging with the auxiliary battery, the smartphone can be charged even without a separate cable. The smartphone battery charging method can be varied.

Fig. 3 is a view schematically showing the configuration of the radio discharging portion of Fig. 1;

이하, 첨부된 도면을 참고하여 본 발명인 무선 충방전 배터리 및 그 충방전 방법을 상세하게 설명한다.Hereinafter, a wireless charging / discharging battery and a charging / discharging method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명인 무선 충방전 베터리의 구성을 개략적으로 도시한 도면이다.1 is a view schematically showing a configuration of a wireless charging / discharging battery according to the present invention.

도 1을 참조하면, 본 발명인 무선 충방전 베터리는 기존 아무곳에서나 구할 수 있는 스마트폰 충전이 가능한 보조베터리, 그 보조베터리 아래쪽에 보조베터리를 무선 충전 하게 하기 위한 무선 충전부 및 보조베터리 위쪽에 스마트폰을 무선 충전 하게 하기 위한 무선 방전부를 포함하고 있다.Referring to FIG. 1, the wireless charging / discharging battery of the present invention includes a secondary battery capable of charging a smartphone, which can be obtained from any place, a wireless charging unit for charging the secondary battery wirelessly below the secondary battery, And a wireless discharge unit for wirelessly charging the battery.

도 2을 참고하면, 무선 충전부는 외부에 있는 무선 충전이 가능한 송신부로 부터 전력을 공급받는다. 전력을 받는 수신코일은 LC 공진을 통해 전력을 공급받는데 이때 LC 공진을 위한 적절한 커패시터가 포함되어야한다. 이렇게 전달 받은 교류 전력은 배터리 충전을 위해 직류로 변환 해야 되는데 이 과정을 해주는게 직류전환 장치이다. 직류 전환 장치를 통화한 전력은 이제 마지막으로 배터리를 충전하기 위해 5V로 변환해주어야 되는데 이 과정은 전압 변환장치에 의해 진행된다. 전압 변환장치에 의해 전달된 5V 전력이 베터리를 충전시킨다.Referring to FIG. 2, the wireless charging unit receives power from an external wireless transmission-capable transmission unit. The receiving coil receiving power is supplied with power through LC resonance, at which time a suitable capacitor for LC resonance should be included. This AC power is converted to DC for charging the battery. The power to talk to the DC converter is now finally converted to 5V to charge the battery, which is done by a voltage converter. The 5V power delivered by the voltage converter charges the battery.

도 3을 참고하면, 무선 방전부는 배터리로 부터 직류 전력을 전달받는다. 무선 방전을 위해서는 교류전력이 필요하므로 교류 전환 장치를 통해 직류 전력을 교류로 바꿔준다. 바뀐 교류 신호는 적당한 주파수로 공진 되게 하는 LC 공진 커패시터를 포함하는 송신코일을 통해 무선충전이 가능한 스마트폰에 전력을 공급한다.Referring to FIG. 3, the radio discharge unit receives DC power from the battery. For radio discharge, AC power is required, so DC power is converted to AC through AC switching device. The alternating AC signal powers the wirelessly chargeable smartphone via a transmit coil that includes an LC resonant capacitor that resonates at a moderate frequency.
