A battery management system may comprise: an integrated circuit for detecting cell voltage values of a plurality of cells constituting a battery module, and generating an alarm signal indicating whether the battery module is overcharged or over-discharged, on the basis of the cell voltage values; a battery controller for receiving the cell voltage values from the integrated circuit, determining on the basis of the cell voltage values whether the battery module is overcharged or over-discharged, and outputting a first control signal in response to a result of the determination; a logic circuit for outputting a second control signal from the first control signal and the alarm signal; a delay circuit for delaying the alarm signal input from the integrated circuit for a predetermined time, and transferring the delayed alarm signal to the logic circuit; and an operation unit for controlling charging/discharging of the battery module according to the second control signal.

    L'invention concerne un système de gestion de batterie pouvant comprendre : un circuit intégré permettant de détecter des valeurs de tension de cellule d'une pluralité de cellules constituant un module de batterie et de générer un signal d'alarme indiquant si le module de batterie est surchargé ou sur-déchargé sur la base des valeurs de tension de cellule ; un dispositif de commande de batterie permettant de recevoir les valeurs de tension de cellule provenant du circuit intégré, de déterminer sur la base des valeurs de tension de cellule si le module de batterie est surchargé ou sur-déchargé et de délivrer en sortie un premier signal de commande en réponse à un résultat de la détermination ; un circuit logique permettant de délivrer en sortie un second signal de commande à partir du premier signal de commande et du signal d'alarme ; un circuit de retard permettant de retarder le signal d'alarme entré à partir du circuit intégré pendant un temps prédéterminé et de transférer le signal d'alarme retardé au circuit logique ; et une unité de fonctionnement permettant de commander la charge/décharge du module de batterie en fonction du second signal de commande.

    배터리 관리 시스템은, 배터리 모듈을 구성하는 복수의 셀에 대해 셀 전압값을 검출하며, 상기 셀 전압값에 기초하여 상기 배터리 모듈의 과충전 또는 과방전 여부를 가리키는 알람 신호를 생성하는 집적회로, 상기 집적회로로부터 상기 셀 전압값을 수신하며, 상기 셀 전압값에 기반하여 상기 배터리 모듈의 과충전 또는 과방전 여부를 판정하고, 상기 판정의 결과에 대응하여 제1제어 신호를 출력하는 배터리 제어기, 상기 제1제어 신호 및 상기 알람 신호로부터, 제2제어 신호를 출력하는 논리회로, 상기 집적회로로부터 입력되는 상기 알람 신호를 소정 시간 지연시켜 상기 논리회로로 전달하는 지연회로, 및 상기 제2제어 신호에 따라서, 상기 배터리 모듈의 충방전을 제어하는 구동부를 포함할 수 있다.
