A battery management device, according to one embodiment disclosed in the present document, comprises a voltage measurement unit for measuring the voltage of each of a plurality of battery banks, and a controller, wherein the controller may select a first value of each of the plurality of battery banks on the basis of a first value which is the amount of change in voltage during a certain period of each of the plurality of battery banks and a second value which is the standard deviation of the voltage change amount per unit time of each of the plurality of battery banks; set the ranking of each of the plurality of battery banks on the basis of a first reference value indicating a ratio of the selected first value of each of the plurality of battery banks to the average value of the selected first value of each of the plurality of battery banks; and diagnose that there is an abnormality in at least one of the plurality of battery banks on the basis of the ranking of each of the plurality of battery banks at a specific point in time.

    Selon un mode de réalisation divulgué dans le présent document, un dispositif de gestion de batterie comprend une unité de mesure de tension permettant de mesurer la tension de chaque banc d'une pluralité de bancs de batterie, ainsi qu'un dispositif de commande, le dispositif de commande pouvant sélectionner une première valeur de chaque banc de la pluralité de bancs de batterie d'après une première valeur qui est la quantité de variation de tension pendant une certaine période de chaque banc de la pluralité de bancs de batterie et une seconde valeur qui est l'écart-type de la quantité de variation de tension par unité de temps de chaque banc de la pluralité de bancs de batterie ; définir le classement de chaque banc de la pluralité de bancs de batteries d'après une première valeur de référence indiquant un rapport entre la première valeur sélectionnée de chaque banc de la pluralité de bancs de batteries et la valeur moyenne de la première valeur sélectionnée de chaque banc de la pluralité de bancs de batteries ; et diagnostiquer l'existence d'une anomalie dans au moins un banc de la pluralité de bancs de batteries d'après le classement de chaque banc de la pluralité de bancs de batteries à un instant spécifique.

    본 문서에 개시된 일 실시예에 따른 배터리 관리 장치는 복수의 배터리 뱅크 각각의 전압을 측정하는 전압 측정부 및 컨트롤러를 포함하고, 상기 컨트롤러는 상기 복수의 배터리 뱅크 각각의 일정 주기 동안의 전압의 변화량인 제1 값과 상기 복수의 배터리 뱅크 각각의 단위 시간당 전압 변화량의 표준편차인 제2 값을 기초로 상기 복수의 배터리 뱅크 각각의 제1 값을 선택하고, 상기 복수의 배터리 뱅크 각각의 선택된 제1 값의 평균값 대비 상기 복수의 배터리 뱅크 각각의 선택된 제1 값의 비율을 나타내는 제1 기준값을 기초로 상기 복수의 배터리 뱅크 각각의 순위를 설정하고, 특정 시점에 있어서의 복수의 배터리 뱅크 각각의 순위에 기초하여 상기 복수의 배터리 뱅크 중 적어도 하나의 배터리 뱅크에 대해 이상이 있음을 진단할 수 있다.
