Abstract:
(EN) According to a method of the present invention, a Kalman filter unit comprises: a first Kalman filter that performs a filter operation in accordance with changes in the state of charge of a battery; and a second Kalman filter that performs a filter operation according to changes in the number of uses of the battery, wherein the first Kalman filter, in a state where the first Kalman filter has received a plurality of entropy values including an actual entropy value and an expected entropy value, on the basis of changing state of charge of the battery, outputs a corrected actual entropy change rate, at the same time that the first Kalman filter is repeatedly operated, and the second Kalman filter periodically updates an entropy model, in a state where the second Kalman filter has received both the actual entropy change rate of the first Kalman filter and an expected aging entropy change rate reflecting aging due to an increase in the number of uses of the battery, and the first Kalman filter tracks an entropy change by means of information about changes in the state of charge of the battery supplied from the entropy model.
(FR) Selon un procédé fourni par la présente invention, un ensemble filtre de Kalman comprend : un premier filtre de Kalman qui effectue une opération de filtre conformément à un changement d'un état chargé d'une batterie ; et un second filtre de Kalman qui effectue une opération de filtre en fonction d'un changement du nombre d'utilisations de la batterie, le premier filtre de Kalman, dans un état dans lequel il reçoit une pluralité de valeurs d'entropie comprenant une valeur d'entropie de mesure réelle et une valeur d'entropie attendue, en fonction de l'état de charge modifié de la batterie, délivrant un taux de changement d'entropie de mesure réelle corrigé, en même temps que le premier filtre de Kalman est exploité de manière répétée ; le second filtre de Kalman mettant à jour périodiquement un modèle d'entropie, dans un état dans lequel il reçoit à la fois le taux de changement d'entropie de mesure réelle du premier filtre de Kalman et un taux de changement d'entropie de vieillissement attendu reflétant le vieillissement dû à une augmentation du nombre d'utilisations de la batterie ; et le premier filtre de Kalman suivant un changement d'entropie au moyen d'informations concernant le changement de l'état chargé de la batterie fourni par le modèle d'entropie.
(KO) 본 발명에 따른 방법은 상기 칼만 필터부는 배터리 충전상태 변화에 따라 필터 동작하는 제1 칼만 필터; 및 배터리의 사용회수 변화에 따라 필터 동작하는 제2 칼만 필터;를 포함하고, 상기 제1 칼만 필터에서는 변경되는 배터리 충전 상태를 통해 실측 엔트로피값 및 예상 엔트로피값을 포함한 복수의 엔트로피값을 입력받은 상태에서 보정된 실측 엔트로피 변화율을 출력하는 것과 동시에 반복적으로 동작되고, 상기 제2 칼만필터에서는 상기 제1 칼만 필터의 실측 엔트로피 변화율을 입력받는 것과 동시에 배터리사용 회수 증가에 따른 노화를 반영한 예상 노화 엔트로피 변화율을 입력받은 상태에서, 엔트로피 모델을 주기적으로 업데이트하고, 상기 제1 칼만 필터에서는 엔트로피 모델로부터 공급되는 배터리 충전상태 변경 정보에 의해 엔트로피 변화를 추적한다.
