A battery monitoring device, according to the present invention, is for a battery assembly provided with: a housing; and a plurality of battery cells received inside the housing. The battery monitoring device comprises: a first sensor for detecting the internal temperature of the housing; a second sensor for detecting the internal pressure of the housing; a third sensor for detecting internal gas of the housing; a power supply circuit for generating an operating voltage by using direct current power of the battery assembly; and a controller for, by using the operating voltage, switching the first sensor, the second sensor and the third sensor from a stopped state into an operating state. The controller monitors internal abnormalities of the battery assembly on the basis of detection values collected from the respective sensors which are in the operating state. Dispositif de surveillance de batterie qui, selon la présente invention, est destiné à un ensemble batterie pourvu : d'un boîtier ; et d'une pluralité d'éléments de batterie reçus à l'intérieur du boîtier. Le dispositif de surveillance de batterie comprend : un premier capteur pour détecter la température interne du boîtier ; un deuxième capteur pour détecter la pression interne du boîtier ; un troisième capteur pour détecter un gaz interne du boîtier ; un circuit d'alimentation électrique pour générer une tension de fonctionnement à l'aide d'une puissance à courant continu de l'ensemble batterie ; et un dispositif de commande pour, en utilisant la tension de fonctionnement, commuter le premier capteur, le deuxième capteur et le troisième capteur d'un état arrêté à un état de fonctionnement. Le dispositif de commande surveille des anomalies internes de l'ensemble batterie sur la base de valeurs de détection collectées à partir des capteurs respectifs qui sont dans l'état de fonctionnement. 본 발명에 따른 배터리 감시 장치는, 하우징 및 상기 하우징 내부에 수납되는 복수의 배터리 셀을 가지는 배터리 어셈블리를 위한 것이다. 상기 배터리 감시 장치는, 상기 하우징의 내부 온도를 검출하는 제1 센서; 상기 하우징의 내부 압력을 검출하는 제2 센서; 상기 하우징의 내부 가스를 검출하는 제3 센서; 상기 배터리 어셈블리의 직류 전력을 이용하여 동작 전압을 생성하는 전원 회로; 및 상기 동작 전압을 이용하여, 상기 제1 센서, 상기 제2 센서 및 상기 제3 센서를 정지 상태로부터 기동 상태로 전환하는 컨트롤러를 포함한다. 상기 컨트롤러는, 기동 상태인 각 센서로부터 수집된 검출값을 기초로, 상기 배터리 어셈블리의 내부적 이상을 감시한다.
