Abstract

A method for determining at least one aging state of a first plurality of electrical energy store units. The method includes: a) ascertaining the number of balancing operations already carried out between the first plurality of electrical energy store units within a predefined first time interval and/or the total converted energy quantity during a balancing operation between the first plurality of electrical energy store units and/or a first measure of dispersion of a particular state of charge-characterizing parameter of the first plurality of electrical energy store units; b) determining the at least one aging state of the first plurality of electrical energy store units as a function of the number of balancing operations already carried out and/or as a function of the total converted energy quantity during a balancing operation and/or as a function of the first measure of dispersion.
