The present invention relates to a battery state estimation method and a battery system providing same. The battery system of the present invention comprises: a battery including a plurality of battery cells; and a battery management system (BMS) that calculates a first variation of state of charge (SOC), which is the difference between a first SOC calculated at a first predetermined time before the beginning of electrical conduction between the battery and an external device and a second SOC calculated at a second time when the electrical conduction is ended, and a second variation of SOC, which is the difference between the first SOC and a third SOC calculated at a third time when a predetermined time elapses from the second time, wherein the BMS estimates a state of health (SOH) of the battery on the basis of the first variation of SOC and the second variation of SOC.

    La présente invention concerne un procédé d'estimation d'état de batterie et un système de batterie le fournissant. Le système de batterie de la présente invention comprend : une batterie comprenant une pluralité d'éléments de batterie ; et un système de gestion de batterie (BMS) qui calcule une première variation d'état de charge (SOC), qui est la différence entre un premier SOC calculé à un premier instant prédéterminé avant le début de la conduction électrique entre la batterie et un dispositif externe et un deuxième SOC calculé à un deuxième instant où la conduction électrique est terminée, et une deuxième variation de SOC, qui est la différence entre le premier SOC et un troisième SOC calculé à un troisième instant lorsqu'un temps prédéterminé s'écoule à partir du deuxième instant, le BMS estimant un état de santé (SOH) de la batterie sur la base de la première variation de SOC et de la deuxième variation de SOC

    본 발명은, 배터리 상태 추정 방법 및 그 방법을 제공하는 배터리 시스템에 관한 것으로, 본 발명의 배터리 시스템은, 복수의 배터리 셀을 포함하는 배터리, 그리고 상기 배터리와 외부 장치 간 통전이 시작되기 전 소정의 제1 시점에서 산출된 제1 충전상태(State of Charge, SOC)와 상기 통전이 종료된 제2 시점에서 산출된 제2 충전상태 간의 차이값인 제1 충전상태 변화량, 및 상기 제1 충전상태와 상기 제2 시점으로부터 소정의 시간이 경과한 제3 시점에서 산출된 제3 충전상태 간의 차이값인 제2 충전상태 변화량을 산출하는 BMS(Battery Management System)을 포함하고, 상기 BMS는 상기 제1 충전상태 변화량 및 상기 제2 충전상태 변화량에 기초하여 상기 배터리의 건강 상태(State of Health, SOH)를 추정한다.
