Zusammenfassung: | An embodiment provides a method for estimating a state-of-health of a battery, comprising the steps of: storing a charging time measured in each of a plurality of terminal voltage section as a reference charging time, for a battery in a reference state-of-health charged with a constant current; in a constant current charging mode of one battery, storing a charging time of each of N terminal voltage sections (N is a natural number equal to or greater than 2) as a comparative charging time, and calculating a value of ratio of the comparative charging time to the reference charging time for each of the N terminal voltage sections; and estimating a state-of-health of the one battery by substituting the N ratio values to a pre-trained machine learning model.
Mode de réalisation concernant un procédé d'estimation d'un état de santé d'une batterie, comprenant les étapes consistant à : stocker un temps de charge mesuré dans chacune d'une pluralité de sections de tension de borne en tant que temps de charge de référence, pour une batterie dans un état de santé de référence chargé avec un courant constant ; dans un mode de charge à courant constant d'une batterie, le stockage d'un temps de charge de chacune des N sections de tension de borne (N étant un nombre naturel égal ou supérieur à 2) en tant que temps de charge comparatif, et le calcul d'une valeur de rapport du temps de charge comparatif au temps de charge de référence pour chacune des N sections de tension de borne ; et l'estimation d'un état de santé de la batterie en substituant les N valeurs de rapport à un modèle d'apprentissage machine pré-entraîné.
일 실시예는, 정전류 충전되는 기준 노화상태의 배터리에 대해, 복수의 단자전압구간 각각에서 측정한 충전시간을 기준충전시간으로 저장하는 단계; 일 배터리의 정전류 충전모드에서, N(N은 2 이상의 자연수)개의 단자전압구간 각각에 대한 충전시간을 비교충전시간으로 저장하고, 상기 기준충전시간과 상기 비교충전시간의 비율값을 상기 N개의 단자전압구간 각각에 대해 계산하는 단계; 및 N개의 상기 비율값을 미리 학습된 기계학습모델에 대입하여 상기 일 배터리의 노화상태를 추정하는 단계를 포함하는 배터리의 노화상태 추정 방법을 제공한다. |
