배터리 진단 장치 및 배터리 진단 방법이 개시된다. 본 발명에 따른 배터리 진단 장치는, 배터리 셀의 충방전 특성을 나타내는 미분 프로파일을 획득하는 데이터 처리부, 상기 미분 프로파일에 복수의 피크 포인트가 존재하는 경우, 상기 복수의 피크 포인트 중의 어느 둘인 제1 피크 포인트 및 제2 피크 포인트를 기초로, 피크 비교값을 결정하는 연산부, 및 상기 피크 비교값을 기초로, 상기 배터리 셀의 상태를 진단하는 진단부를 포함한다.

    A battery diagnosis apparatus and a battery diagnosis method are disclosed. The battery diagnosis apparatus according to the present invention comprises: a data processing unit which acquires a differential profile representing the charge-discharge characteristics of a battery cell; a calculation unit which, when a plurality of peak points exist in the differential profile, determines a peak comparison value on the basis of a first peak point and a second peak point that are any two of the plurality of peak points; and a diagnosis unit which diagnoses a state of the battery cell on the basis of the peak comparison value.
