چکیده

Diese Arbeit beschäftigt sich mit der Entwicklung und Implementierung eines Alterungsmodells für Lithium-Ionen Batterien. Das Modell basiert auf der ArrheniusGleichung für die Alterung über der Zeit sowie auf einer Polynomfunktion welche die Alterung über den Zyklen abbildet und ermöglicht die Simulation des Alterungsverhaltens einer Batterie unter Berücksichtigung der Batterietemperatur und des Ladezustandes. Der entwickelte Alterungsalgorithmus kann für eine große Anzahl an Simulationsszenarien, in welchen das Alterungsverhalten von Lithium-Ionen Batterien unter Berücksichtigung der oben genannten Einflüsse berechnet werden soll, verwendet werden. Ein mögliches Anwendungsszenario ist die Bestimmung von Ladezustandund Temperaturintervallen in welchen eine Lithium-Ion Batterie in automobilen Anwendungen betrieben werden muss um eine möglichst lange Lebensdauer zu erreichen.
