Abstract

Die Erfindung betrifft ein Verfahren zur Steuerung oder Regelung der Spannung einzelner Zellen (Z1... ZN) in einem Zellstapel eines Energiespeichers, insbesondere eines Energiespeichers in einem Kraftfahrzeug-Bordnetz. Das Verfahren weist folgende Schritte auf: a) Ermitteln der Zelle (Z1... ZN) im Zellstapel mit dem niedrigsten Ladezustand und optional mit dem höchsten Ladezustand. b) Parallelschalten eines Zwischenspeichers (C, B) mit mindestens einer Zelle (Z1... ZN), bis sich die Ladezustände der betreffenden Zelle(n) (Z1,... ZN) und des Zwischenspeichers (C, B) angeglichen haben. c) Lösen der Verbindung des Zwischenspeichers (C, B) und der betreffenden Zelle(n) (Z1... ZN). d) Parallelschalten des Zwischenspeichers (C, B) mit der in a) ermittelten Zelle (Z1... ZN) mit dem niedrigsten Ladezustand, bis diese und der Zwischenspeicher in ihren Spannungen angeglichen sind. e) Durchführen der Schritte a) bis d) bis die Spannungen der einzelnen Zellen (Z1... ZN) des Zellstapels bis auf eine vorgegebene zulässige Abweichung in den Ruhespannungen angeglichen sind.
