본 발명은, 배터리 팩 및 자동차 시스템에 관한 것으로, 본 발명의 배터리 팩은, 소정의 전압을 공급하는 전원과 접지단 사이에 직렬로 연결되어 있는 제1 저항 및 제2 저항, 상기 제1 저항 및 상기 제2 저항을 감싸는 케이스, 및 상기 제2 저항의 일단 및 타단 사이에 병렬 연결되고 상기 케이스 외부에 위치하는 가변 저항을 포함하는 검출 전압 측정부, 그리고 냉각수의 전도성에 기초하여 산출된 기준 범위에 상기 제1 저항과 상기 제2 저항의 접점의 검출 전압이 속하면, 상기 냉각수의 누출을 진단하는 냉각수 누출 진단부를 포함한다.

    The present invention relates to a battery pack and a vehicle system. The battery pack of the present invention comprises: a detection voltage measurement unit including a first resistor and a second resistor connected in series between a power source supplying a predetermined voltage and a ground terminal, a case surrounding the first resistor and the second resistor, and variable resistors connected in parallel between one end and the other end of the second resistor and positioned outside the case; and a cooling water leakage diagnosing unit for diagnosing leakage of cooling water when the voltage detected at the point of contact of the first resistor and the second resistor is within a reference range calculated on the basis of the conductivity of the cooling water.
