Title: (DE) STEUERUNGSVORRICHTUNG UND -VERFAHREN ZUM ENTLADEN EINER WIEDERAUFLADBAREN BATTERIE
(EN) CONTROL DEVICE AND METHOD FOR DISCHARGING A RECHARGEABLE BATTERY
(FR) DISPOSITIF ET PROCÉDÉ DE COMMANDE POUR DÉCHARGER UNE BATTERIE RECHARGEABLE
Abstract:
(EN) The invention refers to a control device (6) for controlling discharging of a rechargeable battery (2), the control device (6) being configured to: determine the voltage (Vx) of the battery (2) during discharging of the battery (2), stop discharging, when the determined voltage (Vx) falls below a first predetermined lower voltage limit (Vmin1), determine the voltage (Vx) of the battery (2) after stopping discharging, determine the voltage difference (ΔVx) between the first predetermined lower voltage limit (Vmin1) and the determined voltage of the battery (2) after stopping discharging, and continue discharging, when the determined voltage difference (ΔVX) exceeds a predetermined threshold (ΔVT). The invention also refers to a corresponding method of controlling discharging of a rechargeable battery (2).
(FR) L'invention concerne un dispositif de commande (6) permettant de commander la décharge d'une batterie rechargeable (2), le dispositif de commande (6) étant configuré pour : déterminer la tension (Vx) de la batterie (2) pendant la décharge de la batterie (2), arrêter la décharge, quand la tension déterminée (Vx) devient inférieure à une première limite de tension inférieure prédéterminée (Vmin1), déterminer la tension (Vx) de la batterie (2) après l'arrêt de la décharge, déterminer la différence de tension (ΔVx) entre la première limite de tension inférieure prédéterminée (Vmin1) et la tension déterminée de la batterie (2) après l'arrêt de la décharge, et poursuivre la décharge, lorsque la différence de tension déterminée (ΔVX) dépasse un seuil prédéterminé (ΔVT). L'invention concerne également un procédé correspondant de commande de la décharge d'une batterie rechargeable (2).
