An apparatus for diagnosing a battery, according to one embodiment of the present invention, comprises: a profile acquisition unit for acquiring a differential profile for the capacity and the voltage of a battery; a profile correction unit which determines a target C-rate corresponding to the differential profile, and which corrects the differential profile on the basis of an overvoltage profile corresponding to the target C-rate, so as to generate a correction profile; and a control unit for determining a target peak in the correction profile, and diagnosing the state of the battery on the basis of the behavior of the determined target peak.

    Un appareil de diagnostic d'une batterie, selon un mode de réalisation de la présente invention, comprend : une unité d'acquisition de profil pour acquérir un profil différentiel pour la capacité et la tension d'une batterie ; une unité de correction de profil qui détermine un taux C cible correspondant au profil différentiel, et qui corrige le profil différentiel sur la base d'un profil de surtension correspondant au taux C cible, de sorte à générer un profil de correction ; et une unité de commande pour déterminer un pic cible dans le profil de correction, et diagnostiquer l'état de la batterie sur la base du comportement du pic cible déterminé.

    본 발명의 일 실시예에 따른 배터리 진단 장치는 배터리의 용량과 전압에 대한 미분 프로파일을 획득하도록 구성된 프로파일 획득부; 상기 미분 프로파일에 대응되는 타겟 C-rate를 결정하고, 상기 타겟 C-rate에 대응되는 과전압 프로파일에 기반하여 상기 미분 프로파일을 보정함으로써 보정 프로파일을 생성하도록 구성된 프로파일 보정부; 및 상기 보정 프로파일에서 타겟 피크를 결정하고, 결정된 타겟 피크의 거동에 기반하여 상기 배터리의 상태를 진단하도록 구성된 제어부를 포함한다.
