Abstract:
(EN) Disclosed are an apparatus and a method for acquiring degradation information of a lithium-ion battery cell. An apparatus according to one embodiment estimates a first anode use area related to a first health status of a lithium-ion battery cell. The apparatus estimates a second anode use area related to a second health status of the lithium-ion battery cell. Then, the apparatus calculates a variance of a maximum storage capacity of an anode of the lithium-ion battery cell for a period of time from the first health status to the second health status on the basis of the first and second anode use areas.
(FR) L'invention concerne un appareil et un procédé d'acquisition d'informations de dégradation d'une cellule de batterie au lithium-ion. Un appareil selon un mode de réalisation estime une première zone d'utilisation d'anode associée à un premier état d'une cellule de batterie au lithium-ion. L'appareil estime une seconde zone d'utilisation d'anode associée à un second état de la cellule de batterie au lithium-ion. Ensuite, l'appareil calcule une variance d'une capacité de stockage maximale d'une anode de la cellule de batterie au lithium-ion pendant un laps de temps entre le premier état et le second état en fonction des première et seconde zones d'utilisation d'anode.
(KO) 리튬 이온 배터리 셀의 퇴화 정보를 획득하는 장치 및 방법이 개시된다. 일 실시예에 따른 장치는, 상기 리튬 이온 배터리 셀의 제1 건강 상태와 관련된 제1 양극 사용 영역을 추정한다. 상기 장치는, 상기 리튬 이온 배터리 셀의 제2 건강 상태와 관련된 제2 양극 사용 영역을 추정한다. 그 다음, 상기 장치는, 상기 제1 양극 사용 영역 및 상기 제2 양극 사용 영역을 기초로, 상기 제1 건강 상태로부터 상기 제2 건강 상태까지의 기간에 대한 상기 리튬 이온 배터리 셀의 양극의 최대 저장 용량의 변화량을 산출한다.
