A method for controlling a battery according to an embodiment of the present invention is a method for controlling a battery performed by a BMS, wherein the method may comprise the steps of: when there is no request related to use of a battery system from a higher-level system for a predetermined period of time, performing a procedure for switching the state of a battery pack to a standby mode, which is a low-power state; when a battery system activation request is received from the higher-level system during performance of a plurality of operations included in the procedure for switching to the standby mode, exiting the procedure for switching to the standby mode in response to the corresponding request; and transitioning the state of the battery pack to a normal state. Un procédé de commande d'une batterie selon un mode de réalisation de la présente invention est un procédé de commande d'une batterie réalisé par un système de gestion de batterie, le procédé pouvant comprendre les étapes consistant à : lorsqu'il n'y a pas de demande relative à l'utilisation d'un système de batterie en provenance d'un système de niveau supérieur pendant une période de temps prédéterminée, réaliser une procédure pour commuter l'état d'un bloc-batterie vers un mode de veille, qui est un état de faible puissance ; lorsqu'une demande d'activation de système de batterie est reçue en provenance du système de niveau supérieur pendant la réalisation d'une pluralité d'opérations comprises dans la procédure de commutation vers le mode de veille, sortir de la procédure de commutation vers le mode de veille en réponse à la demande correspondante ; et faire passer l'état du bloc-batterie à un état normal. 본 발명의 실시예에 따른 배터리 제어 방법은 BMS에 의해 수행되는 배터리 제어 방법으로서, 일정 시간 동안 상위 시스템으로부터 상기 배터리 시스템의 사용과 관련한 요청이 없는 경우 상기 배터리 팩의 상태를 저전력 상태인 대기 모드로 전환하는 절차를 수행하는 단계; 상기 대기 모드로 전환하는 절차에 포함된 복수의 동작을 수행하던 중 상기 상위 시스템으로부터 배터리 시스템 활성화 요청이 수신되는 경우 해당 요청에 대해 응답하여, 상기 대기 모드로 전환하는 절차를 탈출하는 단계; 및 상기 배터리 팩의 상태를 정상 상태로 천이하는 단계를 포함할 수 있다.
