Parameters required for the mathematical modeling of the battery can be obtained based on the characteristics of the battery manufacturer. One approach is to build a parameter derive system which is established upon equations extracted from critical points of the characteristics in steady state.
With the increase in state dimensions and over-fitting problems, calculations will become more complicated. The battery model must simultaneously meet the requirements for accurately capturing the dynamic characteristics of the battery in terms of accuracy and adapting to the real-time performance of the system in terms of complexity.
Classification of battery models One of the first steps of battery modeling is to decide, what is the purpose of the modeling. Every application of the model requires slightly different approaches and parameters. There is no strict rule, how to categorize battery models, same models can belong to more than one class.
Battery modeling involves two categories of electrochemical modeling and electrical circuit modeling. The electrochemical model of a battery is structurally based on the internal electrochemical actions and reactions of a cell. It is not obtained from an electrical network.
An accurate and simple circuit-oriented battery model (COM) has to be established to describe the static as well as dynamic characteristics of the battery. This model monitors the battery behaviour and its parameters. The general approach for modelling involves development of COM and validation of models.
