METHOD FOR OPERATING AN ELECTRICAL ENERGY STORAGE SYSTEM

A method for operating an electrical energy storage system, wherein the electrical energy storage system has a plurality of components which fulfil the same purpose, and the method comprises: acquiring first feature data sets that identify the components in each case unambiguously in the energy storage system; comparing the acquired first feature data sets with second feature data sets stored in a first memory; in the case of a deviation between the first feature data sets and the second feature data sets that is established by the comparison, classifying the deviation; storing a value in a second memory depending on the classification of the deviation; and upon a predefined condition being fulfilled by the stored value, at least partly limiting a functionality of the electrical energy storage system.
