Abstract

A method for detecting the status of an energy storage means (1) provides that its actual values (2, 3, 4) can be supplied to an estimate routine (5). The actual values (2, 3, 4) can be supplied in a decoupled manner to a model-based parameter estimator (5) and to a filter (7), which are subordinate to a monitoring level (12). Parameterization values (8, 11) obtained are supplied to a predictor (17) that extrapolates the behavior of the energy storage means (1).
