Title
(DE) VERFAHREN ZUR VORHERSAGE DER LEISTUNGSFÄHIGKEIT ELEKTRISCHER ENERGIESPEICHER
(EN) METHOD FOR PREDICTING THE POWER CAPACITY OF AN ELECTRICAL ENERGY STORE
(FR) PROCEDE DE PREDICTION DU RENDEMENT D'UN ACCUMULATEUR D'ENERGIE ELECTRIQUE
Abstract
(DE)
Es werden Verfahren und zugehörige Vorrichtungen zur Vorhersage der Leistungsfähigkeit eines elektrischen Energiespeichers, beispielsweise einer Batterie in einem Fahrzeug, beschrieben, bei denen mit Hilfe eines mathematischen Modells für den Energiespeicher dessen Zustandsgrößen und Parameter kontinuierlich adaptiert werden und damit eine Lade- und Entladeleistungsfähigkeit abgeschätzt und vorhergesagt wird.
(EN)
A method and corresponding devices for predicting the power capacity of an electrical energy store are disclosed, for example, for a battery in a vehicle, wherein the status values and parameters for the energy store are continuously adapted using a mathematical model of the energy store and hence a charge and discharge power capacity estimated and predicted.
(FR)
L'invention concerne un procédé et des dispositifs associés permettant de prédire le rendement d'un accumulateur d'énergie électrique, par exemple, d'une batterie d'un véhicule. L'invention est caractérisée en ce que l'on forme un modèle mathématique de l'accumulateur d'énergie dont les grandeurs d'état et paramètres sont adaptés en en continu, ce qui permet d'évaluer et de prédire la capacité de charge et de décharge.
