Abstract
(EN)
The present invention optimizes an SOC use range during operation of a secondary battery system. An assembled battery control unit 150 functions as a secondary battery control device for controlling an assembled battery that is a secondary battery. The assembled battery control unit 150 is provided with: an SOC estimation unit 152 for estimating the state of charge (SOC) of the assembled battery; a voltage drop calculation unit 153 for calculating a voltage drop based on an open-circuit voltage (OCV) and a closed circuit voltage (CCV) of the assembled battery; and a use SOC determination unit 154 for determining, on the basis of the relationship between the SOC estimated by the SOC estimation unit 152 and the voltage drop calculated by the voltage drop calculation unit 153, an SOC range to be used during charging/discharging of the assembled battery.

La présente invention optimise une plage d'utilisation de SOC pendant le fonctionnement d'un système de batterie secondaire. Une unité de commande de batterie assemblée (150) fonctionne comme dispositif de commande de batterie secondaire pour commander une batterie assemblée qui est une batterie secondaire. L'unité de commande de batterie assemblée (150) comprend : une unité d'estimation de SOC (152) destinée à estimer l'état de charge (SOC) de la batterie assemblée; une unité de calcul de chute de tension (153) destinée à calculer une chute de tension sur la base d'une tension de circuit ouvert (OCV) et d'une tension de circuit fermé (CCV) de la batterie assemblée; et une unité de détermination de SOC d'utilisation (154) destinée à déterminer, sur la base de la relation entre le SOC estimé par l'unité d'estimation de SOC (152) et la chute de tension calculée par l'unité de calcul de chute de tension (153), une plage de SOC à utiliser pendant la charge/décharge de la batterie assemblée.
