An embodiment of the present invention relates to a battery protecting device and method by which an accumulated charging duration of a charging current applied to a battery cell is identified, and the accumulated charging duration is compared with a predetermined threshold duration to determine whether to permanently block the charging and discharging operation of the battery cell, thereby preventing lithium from precipitating in the battery cell due to the charging current and causing the battery cell to ignite.

    Un mode de réalisation de la présente invention concerne un dispositif et un procédé de protection de batterie au moyen desquels une durée de charge accumulée d'un courant de charge appliqué à un élément de batterie est identifiée, et la durée de charge accumulée est comparée à une durée de seuil prédéterminée pour déterminer s'il faut bloquer de façon permanente l'opération de charge et de décharge de l'élément de batterie, empêchant ainsi la précipitation du lithium dans l'élément de batterie en raison du courant de charge et, par suite, que l'élément de batterie ne prenne feu.

    본 발명의 실시예에 따른 배터리 보호 장치 및 방법은, 배터리 셀에 인가된 충전 전류의 누적 충전 기간을 확인하고, 상기 누적 충전 기간을 기설정된 임계 기간과 비교하여 상기 배터리 셀의 충방전 동작을 영구적으로 차단할 것인지의 여부를 판단함으로써, 충전 전류로 인해 배터리 셀에 리튬이 석출되어 배터리 셀이 발화되는 것을 방지할 수 있다.
