Abstract

Ziel dieser Arbeit ist der Entwurf und Aufbau einer kontinuierlich arbeitenden, passiven Balancier-Einrichtung für sechs Batteriezellen in Serie, inklusive Zustandsüberwachung (condition monitoring) und Schutzbeschaltung (protection circuits). Für dieses System werden Sensoren für Spannugs- und Strommessung ausgewählt, sowie Schutzmaßnahmen für Übertemperatur und Überspannung als auch eine Fernabschaltung der Balanciereinheit aufgebaut. Zuletzt wurde das ganze System im Labor aufgebaut, getestet und die korrekte Funktion der Balanciereinheit demonstriert.
