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.
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.
This article carried out a comparison study of battery modeling and parameter identification techniques. Three models were considered: the Shepherd, the Rint and the Thevenin battery models. The Shepherd model belongs to the category of mathematical models.
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.
Modelling is a fairly simple process that can be carried out based on the amount of information given. Modelling the charging/discharging profiles of battery systems can be performed using various machine learning tasks such as pattern recognition, clustering and classification.
