본 발명에 따른 배터리 상태 모니터링 장치는, 컨버터 내부의 전류로서 서브 배터리를 충전하는 충전 전류, 컨버터의 출력 전압 및 차량의 외기온도를 측정하는 측정부; 측정부에서 측정된 전류 및 전압을 이용하여 서브 배터리의 임피던스를 계산하는 임피던스 계산부; 및 차량의 외기온도와 서브 배터리의 임피던스를 이용하여 서브 배터리의 상태를 판단하는 판단부를 포함한다.

    A battery condition monitoring apparatus includes a measurer configured to measure a charging current which is an internal current of a converter and is charged into a sub-battery, a charging voltage of the converter, and an ambient temperature of a vehicle, an impedance calculator configured to an impedance of the sub-battery on basis of a voltage and a current each measured by the measurer, and a determiner configured to determine a condition of the sub-battery by using the ambient temperature of the vehicle and the impedance of the sub-battery.
