Title: (DE) VERFAHREN UND VORRICHTUNG ZUR KALKULATION EINER SPANNUNG EINER BATTERIE
(EN) METHOD AND DEVICE FOR ESTIMATING A VOLTAGE OF A BATTERY
(FR) PROCÉDÉ ET DISPOSITIF D'ESTIMATION DE LA TENSION D'UNE BATTERIE
Abstract:
(EN) In a method for estimating a voltage of a battery a given battery model (BM) is provided, wherein the given battery model (BM) is a single particle model. A C-rate of the battery is determined. The battery model (BM) is adapted based on the C-rate. The voltage of the battery is estimated by means of the adapted battery model (BM).
(FR) L'invention concerne un procédé d'estimation de la tension d'une batterie, qui consiste à fournir un modèle de batterie (BM) donné, le modèle de batterie (BM) donné étant un modèle à particule unique ; à déterminer un régime C de batterie, le modèle de batterie (BM) étant adapté en fonction du régime C ; à estimer la tension de la batterie au moyen du modèle de batterie (BM) adapté.
