Abstract

Verfahren zum Betrieb eines Redox-Flow-Batterie-Systems umfassend wenigstens zwei Batteriemodule (1), und wobei das Redox-Flow-Batterie- System eine Messeinrichtung (4, 5) zur Bereitstellung einer Messgröße umfasst, welche ein Maß für den Ladezustand eines jeden Batteriemoduls (1) darstellt, und wobei das Verfahren die folgenden Schritte umfasst: - Zyklischer Betrieb des Redox-Flow-Batterie-Systems; - Erfassen von Messwerten mit der Messeinrichtung (4, 5); - Durchführen von wenigstens zwei Balancing-Eingriffen an einem Batteriemodul (1) während eines Halbzyklus; und wobei der letzte im Halbzyklus durchgeführte Balancing-Eingriff vom Typ „Überkompensieren" ist, und ein für diesen Balancing-Eingriff verwendeter SoC2-Wert mit Hilfe einer vorab trainierten KI vorhergesagt wird.
