Abstract
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.
