Abstract
(DE)
Es wird ein Verfahren zur Bestimmung der Ladezustände (SOC) von Batteriezellen (14) oder Batteriemodulen einer Batterie geschaffen. Das Verfahren wird unter Verwendung einer Mehrzahl von Zellüberwachungseinheiten (16, 32) durchgeführt, von denen jede mehrere von den Batteriezellen (14) oder mindestens ein Batteriemodul überwacht, und weist grundsätzlich die folgenden Schritte auf: Messen der jeweiligen elektrischen Spannung der Batteriezellen (14) oder Batteriemodule durch die Zellüberwachungseinheiten (16, 32), Messen eines Stromes der Batterie, Übermitteln des gemessenen Stromwerts an die Mehrzahl von Zellüberwachungseinheiten (16, 32), und Berechnen eines Ladezustandes (SOC) in jeder von den Zellüberwachungseinheiten (16, 32) für die jeweiligen überwachten Batteriezellen (14) beziehungsweise das jeweilige mindestens eine Batteriemodul. Ferner wird ein Batteriemanagementsystem (21, 31) bereitgestellt, welches dazu eingerichtet ist, das erfindungsgemäße Verfahren durchzuführen. Außerdem werden eine Batterie und ein Kraftfahrzeug mit dem Batteriemanagementsystem (21, 31) zur Durchführung des Verfahrens offenbart.
(EN)
The invention relates to a method for determining the charge state (SOC) of battery cells (14) or battery modules of a battery. Said method is carried out using a plurality of cell monitoring units (16, 32), each unit monitoring several battery cells (14) or at least one battery module, and comprises the following steps: the respective electric current of the battery cells (14) or battery modules is measured by cell monitoring units (16, 32), the battery current is measured, the measured current value is transmitted to the plurality of cell monitoring units (16, 32), and a charge state (SOC) is calculated in each of the cell monitoring units (16, 32) for the respective monitored battery cells (14), or respectively, the at least one battery module. The invention also relates to a battery management system (21, 31) which is designed to carry out the claimed method. The invention further relates to a battery and a motor vehicle comprising a battery management system (21, 31) for carrying out said method.

L'invention concerne un procédé de détermination des états de charge (SOC) d'éléments de batterie (14) ou de modules de batterie d'une batterie. Le procédé est réalisé à l'aide d'une pluralité d'unités de contrôle d'éléments (16, 32) dont chacune contrôle plusieurs éléments de batterie (14) ou au moins un module de batterie. Le procédé comporte les étapes suivantes: mesure de la tension électrique respective des éléments de batterie (14) ou modules de batterie au moyen des unités de contrôle d'éléments (16, 32), mesure d'un courant de la batterie, transmission de la valeur de courant mesurée à la pluralité d'unités de contrôle d'éléments (16, 32) et calcul d'un état de charge (SOC) dans chaque unité de contrôle d'éléments (16, 32) pour les éléments de batterie (14) respectivement contrôlés ou respectivement le au moins un module de batterie. L'invention concerne également un système de gestion de batterie (21, 31) conçu pour la mise en oeuvre du procédé selon l'invention. L'invention concerne également une batterie et un véhicule à moteur comportant le système de gestion de batterie (21, 31) pour la mise en oeuvre du procédé selon l'invention.
