Abstract:
(EN) A battery lifespan prediction apparatus and method are disclosed. The battery lifespan prediction apparatus comprises: a current measurement unit for measuring the current of a battery at a predetermined current cumulative value point; a voltage measurement unit for measuring the voltage of the battery at the predetermined current cumulative value point; a data processing unit for calculating an open circuit voltage (OCV) value of the battery by substituting current and voltage values of the battery in an equation for calculating the terminal voltage of the battery; and a deterioration calculation unit for calculating a capacity retention (CR) rate of the battery by comparing a predetermined current cumulative value and the OCV value of the battery with an OCV table according to pre-stored CR-specific current cumulative values.
(FR) L'invention concerne un appareil et un procédé de prédiction de durée de vie de batterie. L'appareil de prédiction de durée de vie de batterie comprend : une unité de mesure de courant pour mesurer le courant d'une batterie à un point de valeur cumulative de courant prédéterminé ; une unité de mesure de tension pour mesurer la tension de la batterie au point de valeur cumulative de courant prédéterminé ; une unité de traitement de données pour calculer une valeur de tension de circuit ouvert (OCV) de la batterie en substituant les valeurs de courant et de tension de la batterie dans une équation permettant de calculer la tension aux bornes de la batterie ; et une unité de calcul de détérioration pour calculer un taux de rétention de capacité (CR) de la batterie par comparaison d'une valeur cumulative de courant prédéterminée et de la valeur OCV de la batterie avec une table OCV en fonction de valeurs cumulatives de courant spécifiques à la CR pré-mémorisées.
(KO) 배터리 수명 예측장치 및 방법이 개시된다. 배터리 수명 예측장치는 미리 정해진 전류적산치 지점에서 배터리의 전류를 측정하는 전류 측정부, 미리 정해진 전류적산치 지점에서 배터리의 전압을 측정하는 전압 측정부, 배터리의 전류 및 전압 값을 배터리의 단자전압을 산출하는 방정식에 대입하여 배터리의 개방 회로 전압(OCV: Open Circuit Voltage) 값을 산출하는 데이터 처리부 및 미리 정해진 전류적산치 값과 배터리의 개방 회로 전압 값을 미리 저장된 용량유지율(CR: Capacity Retention)별 전류적산치에 따른 개방 회로 전압 테이블과 비교하여 배터리의 용량유지율을 산출하는 열화도 산출부를 포함한다.
