Abstract
A method for performance analysis and use management of a battery module is disclosed, wherein the battery module includes a multitude of interconnected battery cells and a battery management system with a plurality of dedicated analysis/control units (ACUs) that analyze performance of the battery module, the ACUs being assigned to individual battery cells and/or battery blocks of battery module. The method includes measuring current and voltage of one or more of an individual battery cell and a battery block; calculating a charge removal from the one or more of the individual battery cell and the battery block; calculating a loading charge of the one or more of the individual battery cell and the battery block; determining the remaining charge of the one or more of the individual battery cell and the battery block; and failure monitoring of the one or more of the individual battery cell and the battery block.
