Analysis of parameter identification methods for electrical Li-Ion battery modelling

To fulfil lifetime requirements of a HV-Battery by simultaneously keeping drive performance it is indispensable to well-suit the BMS application. Therefore, knowledge of battery aging and the change of the battery model parameters in time are mandatory. Introducing a real time Li-Ion battery model, this article issues the topic of parameter identification and which kind of optimization method fits the best to the optimization problem on hand for stable and fast parameter identification.
