Title (EN) QUICK BATTERY CHARGING SYSTEM
(FR) SYSTÈME DE CHARGE RAPIDE DE BATTERIE
(KO) 전지 급속 충전 시스템
Abstract:
(EN) The present invention provides a quick battery charging system. The system comprises a lithium secondary battery having a porosity of 25 to 35% and a negative electrode loading volume x0. Also, the system comprises a storage unit having, stored therein, information on the negative electrode loading volume (x0) and a lookup table which includes data allowing mapping of information of a first coefficient of an upper bound envelope condition relating to a C-rate of a charging current and expressed by a quadratic function. Also, the system comprises a charging control device which, once charging of the lithium secondary battery starts, reads the information on the negative electrode loading volume (x0) from the storage unit, determines the information of the first coefficient of the quadratic function representing the upper bound envelope condition from the lookup table, determines the range of the C-rate of the charging current by using the information of the first coefficient, and provides the charging current satisfying the determined C-rate range to the lithium secondary battery.
(FR) La présente invention concerne un système de charge rapide de batterie. Le système comprend une batterie secondaire au lithium ayant une porosité de 25 à 35 % et un volume de charge d'électrode négative x0. Le système comprend également une unité de mémoire dans laquelle sont mémorisées des informations sur le volume de charge d'électrode négative (x0) et une table de consultation qui comprend des données permettant la mise en correspondance d'informations d'un premier coefficient d'une condition d'enveloppe de limite supérieure relative à un taux-C d'un courant de charge et exprimée par une fonction quadratique. Le système comprend également un dispositif de commande de charge qui, une fois que la charge de la batterie secondaire au lithium commence, lit les informations sur le volume de charge d'électrode négative (x0) provenant de l'unité de mémoire, détermine les informations du premier coefficient de la fonction quadratique représentant la condition d'enveloppe de limite supérieure provenant de la table de consultation, détermine la plage du taux-C du courant de charge à l'aide des informations du premier coefficient, et fournit le courant de charge satisfaisant la plage de taux-C déterminée à la batterie secondaire au lithium.
(KO) 본 발명은 전지 급속 충전 시스템을 개시한다. 시스템은 기공도가 25 내지 35%이고 음극 로딩량이 x0인 리튬 이차 전지를 포함한다. 또한, 시스템은 2차 함수로 표현되는 충전 전류 씨레이트에 관한 상한 경계 조건의 제1계수 정보를 맵핑할 수 있는 데이터를 포함하는 룩업 테이블과 상기 음극 로딩량(x0)에 관한 정보가 저장된 저장 유닛을 포함한다. 또한, 시스템은 리튬 이차 전지의 충전이 개시되면 상기 저장 유닛으로부터 상기 음극 로딩량(x0)에 관한 정보를 독출하고, 상기 룩업 테이블로부터 상기 상한 경계 조건을 나타내는 2차 함수의 제1계수 정보를 결정하고, 상기 제1계수 정보를 이용하여 충전전류의 씨레이트 범위를 결정하고, 상기 결정된 씨레이트 범위를 충족하는 충전전류를 상기 리튬 이차 전지에 공급하는 충전 제어 장치;를 포함한다.
