배터리 내부 저항을 활용하여 배터리 교체 여부를 정확하게 진단할 수 있는 차량용 배터리 교체 진단 장치 및 그의 배터리 교체 진단 방법에 관한 것으로, 배터리의 내부 저항을 측정하는 측정부, 측정한 내부 저항을 저장하는 저장부, 그리고 내부 저항을 토대로 배터리 교체 여부를 진단하는 제어부를 포함하고, 제어부는, 차량 전원 리셋(reset)이면 차량 시동 후에 제1 내부 저항 또는 제2 내부 저항을 측정하도록 측정부를 제어하고, 측정한 제1, 제2 내부 저항을 업데이트하여 저장부에 저장하며, 현재 제1 내부 저항값을 기존 제1 내부 저항값과 비교하거나 또는 현재 제2 내부 저항값을 기존 제2 내부 저항값과 비교하여 해당 값이 서로 다르면 배터리 교체로 진단할 수 있다.

    An apparatus and a method for diagnosing battery replacement for vehicles may accurately diagnose whether a battery has been replaced using an internal resistance of the battery. The apparatus includes a measurer for measuring the internal resistance of the battery, a storage for storing the measured internal resistance, and a controller for diagnosing whether the battery has been replaced based on the internal resistance. The controller, when vehicle power is reset, controls the measurer to measure a first or second internal resistance after starting a vehicle, updates and stores the measured first or second internal resistance in the storage, compares a current first internal resistance value with a former first internal resistance value or a current second internal resistance value with a former second internal resistance value, and diagnoses that the battery has been replaced when the corresponding values differ from each other.
