Verfahren zur Bestimmung des Ladungszustandes und weiterer physikalischer Groessen eines wiederaufladbaren elektrischen Energiespeichers

Process for the measurement of the physical parameters of rechargeable electric energy storage units, in which the process input parameters of the energy storage unit (I, t, T<-AKKu, T<-Umg, U(t)) are measured and processed in a computer, whereby a predetermined model based on the known principle of indirect measurement is used, said model assuming the form of closed linear or non-linear multi-parametric functions and/or heuristic parameterization providing an estimation, which represents the physical parameters to be measured and their physical interrelationships with which the measured process input parameters are compared, and the model and/or the estimation is adapted for the next measurement.
