Abstract

본 발명은 자동차 밧데리의 내부저항 측정장치 및 방법에 관한 것으로, 상세하게는 밧데리 충전전류에 대한 상대적 내부저항 변화와 충전중 충전상태 변화에 대한 전지(밧데리)의 저항변화를 측정할 수 있게 한 자동차 밧데리의 내부저항 측정장치 및 방법에 관한 것이다. 종래의 밧데리 장치는 자체적인 저항값의 측정이 불분명하여 운전자에게 밧데리 충전상태에 따른 내부정하의 변화에 대한 측정정보를 제공하지 못하거나 표시하지 못하는 문제점이 있었다. 발전기로부터 충전용 전류가 공급되는 파워 서플라이(10)로부터 션트 1과 저항체(Rf)(30)와 션트3(43)과 그라운드(접지)가 직렬 연결되며, 상기 션트1(41)과 저항체(Rf)(30) 사이에 밧데리의 플러스 단자로 연결되는 회로를 형성하고, 상기 밧데리의 마이너스 단자와 션트2(42)와 그라운드 (접지)가 직렬 연결되게 형성하여 상기 션트1(41)과 션트 2(42)와 션트3(43)이 계측기로 신호가 인가되게 구성된다. 이와같이, 본 발명을 이용한 자동차는 밧데리의 자체적인 저항값을 항시 디스플레이할 수 있게 됨으로써, 운전자는 상기 디스플레이되는 저항값에 의하여 밧데리 전해액 교체시기와 밧데리의 관리상태와 교체시기를 용이하게 점검할 수 있게 하는 효과가 있다.The present invention relates to an apparatus and a method for measuring the internal resistance of an automobile battery, and more particularly, a vehicle capable of measuring a change in the resistance of a battery against a change in relative internal resistance to a battery charging current and a change in state of charge during charging. The present invention relates to a battery internal resistance measuring apparatus and method. The conventional battery device has a problem in that the measurement of its own resistance value is unclear so that the driver cannot provide or display the measurement information on the change of internal static charge according to the state of charge of the battery. The shunt 1, resistor (Rf) 30, shunt 3 (43) and ground (ground) are connected in series from the power supply 10 to which the charging current is supplied from the generator, and the shunt 1 (41) and resistor (Rf) are connected in series. And a circuit connected to the positive terminal of the battery, and the negative terminal of the battery, the shunt 2 (42) and the ground (ground) are connected in series to form a circuit connected to the shunt 1 (41) and the shunt 2 ( 42 and shunt 3 43 are configured to apply a signal to the meter. As such, the vehicle using the present invention can always display its own resistance value of the battery, so that the driver can easily check the battery electrolyte replacement time, the battery management state, and the replacement time according to the displayed resistance value. It is effective.
