Abstract:
(EN) A method is described for determining a current, in particular a short-circuit current, of a battery by means of a defined prediction time period. The method according to the invention comprises the following steps: measuring a voltage of the battery, reading a battery state and determining the solution of a differential equation which describes the temporal development of current in the course of the prediction time period using an equivalent circuit model. The differential equation comprises the battery state and the measured voltage. Moreover, a battery management unit for performing the method, a battery with battery management unit and a motor vehicle having the battery or the battery management unit are described.
(FR) L'invention concerne un procédé de détermination d'un courant, en particulier d'un courant de court-circuit, d'une batterie au cours d'une période de prédiction déterminée. Le procédé selon l'invention comprend les étapes suivantes: mesure d'une tension de la batterie ; lecture d'un état de la batterie ; et détermination de la solution d'une équation différentielle qui décrit l'évolution dans le temps du courant au cours de la période de prédiction au moyen d'un modèle de schéma équivalent. L'équation différentielle comprend l'état de la batterie et la tension mesurée. L'invention concerne également une unité de gestion de batterie pour mettre en œuvre le procédé, une batterie comportant l'unité de gestion de batterie et un véhicule automobile comprenant la batterie ou l'unité de gestion de batterie.
(DE) Es wird ein Verfahren zum Bestimmen eines Stroms, insbesondere eines Kurzschlussstroms, einer Batterie über einen bestimmten Prädiktionszeitraum beschrieben. Das erfindungsgemäße Verfahren umfasst folgende Schritte: Messen einer Spannung der Batterie, Auslesen eines Batteriezustands und Bestimmen der Lösung einer Differentialgleichung, die die zeitliche Entwicklung des Stroms im Verlauf des Prädiktionszeitraums mithilfe eines Ersatzschaltbildmodells beschreibt. Die Differentialgleichung umfasst den Batteriezustand und die gemessene Spannung. Ferner wird eine Batteriemanagementeinheit zur Ausführung des Verfahrens, eine Batterie mit der Batteriemanagementeinheit und ein Kraftfahrzeug mit der Batterie oder der Batteriemanagementeinheit beschrieben.
