Description

자동차용 연축전지에 내장 가능한 배터리 센서의 장착 구조{The Mounting Structure of Battery Sensor can be inserted Lead Acid Battery for Vehicle}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mounting structure of a battery sensor,

본 발명은 배터리 센서가 내장된 자동차 시동으로 적용되고 있는 연축전지에 관한 것으로, 더욱 상세하게는, 연축전지 음극 포스트와 셀 사이에 마련된 공간과, 셀과 극주를 전기적으로 연결하기 위한 션트저항과, 션트저항과 연결되어 배터리의 전압과 전류를 연산하여 엔진 ECU로 송부하기 위한 센서부와, 센서부에서 외부 커넥터로의 데이터 통신을 위한 커넥터부와, 션트저항/센서부/커넥터를 배터리 내부의 황산분위기를 피하기 위한 보호부로 구성되어 기존의 포스트에 클램프를 통해 연결 되있는 배터리 센서를 대체하기 위한 시동용 배터리 어셈블리에 관한 것이다.[0001] The present invention relates to a lead-acid battery which is applied to a vehicle starter having a battery sensor, and more particularly to a lead-acid battery having a space provided between a lead-acid battery cathode post and a cell, a shunt resistor for electrically connecting the cell and the pole, A connector portion for data communication from the sensor portion to an external connector, and a shunt resistor / sensor portion / connector connected to the shunt resistor to calculate the voltage and current of the battery and send the calculated voltage and current to the engine ECU, And more particularly to a starter battery assembly for replacing a battery sensor connected to a conventional post via a clamp.

일반적으로, 연축전지(Lead Acid Battery)는 2차 전지의 하나로, 활물질은 납을 주소재를 쓰고 및 전해액으로는 비중 2.7 수준의 묽은 황산용액을 사용하고, 재생이 가능하며, 저렴하고, 특유의 안정성과 저온시동능력을 보유한 보편화 된 에너지 저장장치이다. Generally, a lead acid battery is one of the secondary batteries, the active material is lead, and the electrolyte is a dilute sulfuric acid solution having a specific gravity of 2.7 and can be regenerated, inexpensive, It is a universal energy storage device with stability and low temperature starting capability.

연축전지는 자동차 시동용/보조용 배터리, ESS용, 산업용, 전기운송수단 등에서 널리 이용되고 있다.Lead-acid batteries are widely used in automotive starter / auxiliary batteries, ESS, industrial, and electric vehicles.

연축전지의 충방전 매커니즘은 양극 활물질인 과산화연(PbO2)과, 음극 활물질인 해면상납(Pb), 그리고 전해질인 묽은황산(H2SO)과의 화학반응을 통해 충방전이 발생하게 되는데 이는 완충상태로, 방전시 양극에서는 과산화납에서 4가의 납 양이온과 2가의 산소 음으로 분해되어 음극으로부터 부하를 거쳐 양극으로 전자가 이동하면 4가의 납 양이온으로부터 2가의 납 양이온이 생성되고, 2가의 납 양이온은 전해액에서 해리된 2가의 황산 음이온과 반응하여 황산납이 된다. 그리고 양극판으로부터 자유롭게 분리된 2가의 산소 음이온은 전해액에서 해리된 1가의 수소 양이온과 반응하여 물을 생성하는데, 방전이 진행될수록 묽은 황산의 비중이 낮아진다. Charging and discharging mechanism of lead-acid battery is caused by the chemical reaction between PbO 2 which is a cathode active material, Pb which is an anode active material, and dilute sulfuric acid (H 2 SO) which is an electrolyte. In the cushioning state, when the cathode is decomposed into lead tetravalent cations and bivalent oxygen cations at the cathode at the time of discharging and electrons move from the cathode to the anode through the load, bivalent lead cations are generated from the tetravalent lead cations, The cation reacts with the divalent sulfate anion dissociated from the electrolytic solution to become lead sulfate. The bivalent oxygen anion separated freely from the bipolar plate reacts with the monovalent hydrogen cations dissociated from the electrolyte to form water. As the discharge progresses, the specific gravity of the dilute sulfuric acid decreases.

자동차용 12V 연축전지의 방전 종지전압은 일반적으로 10.5V로 정의하며, 자동차 제너레이터를 통한 상시 부동 충전전압은 14.4V이며, 공칭접압은 12V이다.The discharge end voltage of a 12V battery for automobiles is generally defined as 10.5V, the constant floating charge voltage through a vehicle generator is 14.4V, and the nominal voltage is 12V.

현재 출고중인 자동차의 대부분은 인텔리전트 배터리 센서라는 전장부품이 음극 포스트에 클램프로 일체화 되어 장착되어 나오는데, 배터리 센서는 배터리의 충전상태, 건강상태, 시동능력 등을 판단하여 엔진 ECU에 전달해주는 역할을 한다. 그 원리는 클램프와 연결되는 센서 하우징 양끝단에 결합된 션트저항에서 수시로 변하는 전압 및 전류값을 제조사만의 알고리즘이 적용된 연산을 통해 배터리의 상태를 추정하는 것이다. 추정되는 배터리 상태의 오차는 외기온도, 션트저항 전압감지 정확도, 알고리즘의 정확도, 케이블 및 센서부품의 저항 및 감도, 연축전지 충방전 케미스트리의 비선형성 등에 의해 큰 차이가 있으며, 현재도 배터리 상태 추정 알고리즘은 완벽하지 못한 상태이다.Most of the vehicles currently on the market are equipped with intelligent battery sensors, which are integrated into the cathode posts with clamps. The battery sensor determines the state of charge, health, and starting capability of the battery and transmits it to the engine ECU . The principle is to estimate the state of the battery by computing the voltage and current values that vary from time to time in the shunt resistor connected to both ends of the sensor housing connected to the clamp. Estimated battery condition errors are largely different depending on ambient temperature, shunt resistance voltage detection accuracy, algorithm accuracy, resistance and sensitivity of cable and sensor components, nonlinearity of charge / discharge charge / discharge chemistry, Is not perfect.

상기 연축전지와 배터리 센서의 조합은 전장부품의 증가와 함께 ISG 적용, 발전제어 등에 의해 연비향상 목적으로 탄생했으며, 배터리 센서가 배터리 바깥쪽에 장착되어 있어서 데이터의 외기온에 의한 왜곡과, 외력에 의한 센서 손상, 그리고 배터리 제조사/용량 변경시 센서 오차 확대 등의 문제가 발생하고 있는 상태이다.The combination of the lead storage battery and the battery sensor is intended to improve fuel efficiency by application of ISG and power generation control along with an increase in electrical components. The battery sensor is mounted on the outside of the battery, and distortion due to external temperature, Damage to the battery, and an increase in sensor error when the battery manufacturer / capacity is changed.
