METHOD FOR DETERMINING A CONTROL OBSERVER FOR THE SOC

The invention relates to the creation of a control observer in a structured and at least partially automated manner for any battery type. According to the invention, first a non-linear model of the battery, in the form of a local model network comprising a number of local, linear, time-invariant, dynamic models, which are each valid in certain ranges of the input variables, is determined from the measurement data of a previously determined optimized test plan by means of a data-based modeling method. A local observer is then determined for each local model (LMi) of the model network determined in such a way. The control observer (13) for estimating the SoC then results form a linear combination of the local observers.
