Title
(EN) BATTERY DEVICE AND METHOD FOR PREDICTING BATTERY OUTPUT
(FR) DISPOSITIF DE BATTERIE ET PROCÉDÉ DE PRÉDICTION DE SORTIE DE BATTERIE
(KO) 배터리 장치 및 배터리 출력 예측 방법
Abstract
(EN) A battery device estimates a surface SOC that indicates a potential at an electrode surface of a battery, and predicts, on the basis of the surface SOC, a cut-off voltage, and a request time, the output of the battery for the request time period.
(FR) Un dispositif de batterie estime un SOC de surface qui indique un potentiel au niveau d'une surface d'électrode d'une batterie, et prédit, en fonction du SOC de surface, d'une tension de coupure, et d'un temps de demande, la sortie de la batterie pour la période de temps de demande.
(KO) 배터리 장치는 배터리의 전극 표면에서의 전위를 나타내는 표면 SOC를 추정하고, 표면 SOC, 컷오프 전압 및 요청 시간에 기초해서 요청 시간 동안의 배터리의 출력을 예측한다.
