도 1은 본 발명에 의한 배터리 성능개선기기의 구성도1 is a configuration diagram of a battery performance improving device according to the present invention

본 발명에 대한 도면에 의해 상세히 설명하면, 본 발명에서의 도 1에 의한 전원부(10)에서 공급되는 전원이 화면표시조작부 (20)와 연계하여 콘트롤러(100)와 구성되는 배터리 성능개선기기에 있어서, 온도제어부(30) 및 통신부(40)을 포함하여 콘트롤러(100)를 구성하고, 상기 충전제어부(110)가 외부입력부(50)와 콘트롤러(100)에 의해 제어되는 것을 더 포함하며, 상기 콘트롤러(100)에서 제어신호에 따라 방전제어부(120)가 방전을 수행하도록 방전신호를 송신하며, 상기 콘트롤러(100)에서 고주파펄스발생부(150)에서 발생된 펄스파를 방전제어부(120)에서 증폭된 1차펄스파와, 주변회로로부터 유도된 2차펄스파를 구분하여 회로보호부 (160)를 거쳐 배터리에 공급하며, 본 발명에 의한 배터리 성능개선기기의 구성도로서, 전원공급부, 화면표시조작부, 온도제어부, 통신부, 전류검출부, 전압검출부, 방전제어부, 충전제어부, 고주파펄스부, 미세에너지펄스공급부, 보호회로부, 콘트롤러로 구성된다. 상기 배터리에 정전류가 공급되면 셀내부에서 발생되는 기포가 크게형성되어 성장하면서 기판에 반응할 시간적 여유가 없어 배터리 효율이 저하하는 원인이 되는 것이다. 납산배터리의 경우, 극판에 황산염이 부착되어 충전효율이 떨어지게 되는데 상기와 같은 상황에서는 설페이션 (Su- lfaion) 현상에 의해 정격12V의 전압을 발생하지 못하고 그 이하의 전압이 발생된다. 이때 황산염을 제거할 수 있게 고주파 정역펄스를 교차 발생시켜 공급하여 제거한 후 미세에너지펄스파를 공급하여 황산염이 기판에 부착되지 않도록 미세기포가 보호막처럼 기판에 형성되어 유지하게한다. 리튬배터리의 경우, 에이징현상을 단축시키고 니켈 배터리는 완전 방전되기 이전에 재 충전하면 전기량이 남아 있어도 완전방전으로 기억하는 효과를 가지게 되어 최초 가지고 있던 충전용량보다 충전량이 줄어들면서 아울러 배터리 수명이 줄어드는 현상을 메모리 효과라고 한다. 본 발명에 의한 배터리 성능 개선기기의 전원공급부(10)에서 전원을 화면표시조작부(20)에 공급하고 배터리(200)에 극성을 맞추어 연결한다. 이 상태에서 화면표시조작부(20)의 화면에는 배터리 제조사에서 제공되는 성능시험데이터를 선택할 수 있는 화면이 제공되며 이 화면에서 성능개선시킬 배터리의 제조사의 모델를 선택하여 작업을 개시한다. 배터리는 양극, 음극, 전해액으로 구성되며, 화학반응에 의한 충, 방전이 가능한 화학전지 이다. 이러한 배터리는 사용시간과 관리 방법에 따라 성능이 좌우된다. 이러한 문제점을 니켈배터리에서는 메모리효과, 리튬배터리에서는 에이징현상, 납산배터리에서는 황산염화라고 하며 대부분 충전부족 및 과방전, 자가방전에 의해 성능이 떨어진다. 기존에는 이러한 문제점을 해소하기 위하여 고압의 펄스파를 충전중에 공급하여 단기간에 성능복원을 하지만 과충전 및 열화현상에 의한 배터리 수명단축의 문제점이 발생한다. When described in detail by the drawings for the present invention, the power supplied from the power supply unit 10 according to FIG. 1 in the present invention in the battery performance improving device configured with the controller 100 in conjunction with the display operation unit 20 in , Comprising the temperature control unit 30 and the communication unit 40 to configure the controller 100, the charging control unit 110 further includes that controlled by the external input unit 50 and the controller 100, the controller The discharge control unit 120 transmits a discharge signal to perform discharge according to the control signal at 100, and the controller 100 amplifies the pulse wave generated by the high frequency pulse generator 150 in the discharge control unit 120 The primary pulse spar and the secondary pulse spar derived from the peripheral circuit are separated and supplied to the battery through the circuit protection unit 160. As a configuration diagram of the battery performance improving device according to the present invention, a power supply unit, a screen display operation unit, It is composed of temperature control unit, communication unit, current detection unit, voltage detection unit, discharge control unit, charging control unit, high frequency pulse unit, fine energy pulse supply unit, protection circuit unit, and controller. When a constant current is supplied to the battery, bubbles generated inside the cell are largely formed, and thus there is no time to react to the substrate as it grows, which causes a decrease in battery efficiency. In the case of a lead-acid battery, sulfate is attached to the electrode plate, thereby decreasing the charging efficiency. In the above situation, the voltage of rated 12V cannot be generated due to the phenomenon of sulfur and a voltage lower than that is generated. At this time, cross-generating and supplying high-frequency forward and reverse pulses to remove the sulfates, and then supplying and removing the fine energy pulses, microbubbles are formed and maintained on the substrate like a protective film so that the sulfates do not adhere to the substrate. In the case of a lithium battery, if the aging phenomenon is shortened and the nickel battery is recharged before being completely discharged, it has the effect of remembering it as a full discharge even if the amount of electricity remains. Is called the memory effect. Power is supplied from the power supply unit 10 of the battery performance improving device according to the present invention to the screen display operation unit 20, and the polarity is connected to the battery 200. In this state, a screen for selecting performance test data provided by the battery manufacturer is provided on the screen of the screen display operation unit 20. On this screen, a model of a battery manufacturer to improve performance is selected to start work. The battery is composed of an anode, a cathode, and an electrolyte, and is a chemical cell capable of charging and discharging by chemical reaction. The performance of these batteries depends on the usage time and management method. This problem is called memory effect in nickel battery, aging phenomenon in lithium battery, sulfate in lead acid battery, and most of the performance is poor due to insufficient charge, over-discharge, and self-discharge. Conventionally, in order to solve this problem, high-voltage pulse waves are supplied during charging to restore performance in a short period of time, but there is a problem of shortening the battery life due to overcharge and deterioration.

상기 콘트롤러에서 배터리 기본정보 및 제품정보, 충,방전설정값, 외부 입력자료 저장 등을 기반으로 하여 전압 및 전류 검출을 하여 충전 및 방전에 대한 전류값을 실시간으로 측정하여 콘트롤러에 전송하여 제어하게 된다. 또한 고주파펄스발생부에서 발생한 펄스와 방전제어부에서 송신되는 방전전류량을 회로보호부를 통해 배터리로 전달한다. 상기 충전제어부에서 충전에 대한 기능을 수행하는데, 콘트롤러와 연결된 화면표시조작부를 통하여 송신되는 충전신호를 충전제어부에 전달하여 충전이 진행되도록 한다. 미세에너지 발생부(60)에서 발생되는 에너지펄스를 회로보호부(160)을 거쳐 배터리(200)에 공급하면 니켈배터리에서는 메모리효과, 리튬배터리에서는 에이징현상, 납산배터리에서는 황산염화에 의한 문제점이 해소되어 배터리를 안정적으로 장기적으로 관리할 수 있는 배터리 성능개선기기인 것이다. The controller detects voltage and current based on battery basic information and product information, charging and discharging set values, external input data storage, etc., and measures the current values for charging and discharging in real time and transmits them to the controller for control. . In addition, the pulse generated in the high-frequency pulse generator and the discharge current amount transmitted from the discharge controller are transferred to the battery through the circuit protection unit. The charging control unit performs a function for charging, and the charging signal transmitted through the screen display operation unit connected to the controller is transmitted to the charging control unit so that charging is performed. When the energy pulse generated from the micro-energy generating unit 60 is supplied to the battery 200 through the circuit protection unit 160, the memory effect in the nickel battery, the aging phenomenon in the lithium battery, and the sulfuric acid in the lead acid battery solve the problem. It is a battery performance improving device that can stably manage the battery for a long time.
