Title (EN) METHOD AND DEVICE FOR CALCULATING STATE OF HEALTH IN SECONDARY BATTERY
(FR) PROCÉDÉ ET DISPOSITIF POUR CALCULER L'ÉTAT DE SANTÉ D'UNE BATTERIE SECONDAIRE
(KO) 2차 전지의 잔존수명 연산 방법 및 장치
Abstract: front page image
(EN)A method for calculating the state of health in a secondary battery comprises the following steps: (a) calculating the amount of current of the secondary battery by means of integrating charging/discharging currents of the secondary battery; (b) verifying the charging/discharging state of the secondary battery by inspecting the charging/discharging state or no-load state of the secondary battery; and (c) calculating the state of health in the secondary battery by using the amount of current in the secondary battery, which is calculated from step (a), when the charging/discharging of the secondary battery of step (b) is completed. According to the present invention, an accurate calculation/deduction of the state of health of the secondary battery is enabled based on charging/discharging amounts, unlike existing methods of accurately calculating/deducting the state of health of the secondary battery.
(FR)L'invention porte sur un procédé pour calculer l'état de santé d'une batterie secondaire, lequel procédé comprend les étapes suivantes, consistant à : (a) calculer la quantité de courant de la batterie secondaire par l'intégration de courants de charge/décharge de la batterie secondaire ; (b) vérifier l'état de charge/décharge de la batterie secondaire par inspection de l'état de charge/décharge ou de l'état de non charge de la batterie secondaire ; et (c) calculer l'état de santé de la batterie secondaire par l'utilisation de la quantité de courant dans la batterie secondaire, qui est calculée à partir de l'étape (a), quand la charge/décharge de la batterie secondaire de l'étape (b) est achevée. Selon la présente invention, un calcul/une déduction précis de l'état de santé de la batterie secondaire est permis sur la base des quantités de charge/décharge, contrairement aux procédés existants consistant à calculer/déduire avec précision l'état de santé de la batterie secondaire.
(KO)본 발명의 2차 전지의 잔존수명 연산 방법은 (a) 2차 전지의 충방전 전류 적산에 의해 상기 2차 전지의 전류량을 연산하는 단계; (b) 상기 2차 전지의 충방전 또는 무부하 상태 검사를 수행하여 상기 2차 전지의 충방전 상태를 확인하는 단계; 및 (c) 상기 단계(b)에서 상기 2차 전지의 충방전이 종료되면 상기 단계(a)에서 연산된 상기 2차 전지의 전류량를 이용하여 상기 2차 전지의 잔존수명을 연산하는 단계를 포함한다. 본 발명에 의하면, 2차 전지의 잔존수명을 정확히 연산/도출하는데 있어 기존 방법과 다르게 충/방전량 기반으로 2차 전지의 잔존수명을 정확히 연산/도출이 가능하다.
