What is a battery model based on?

3.2. Battery modeling The battery model implemented in this study is based on the Rint equivalent circuit model [ 43] which is composed of a variable voltage source ( OCVcell) and a resistance in series ( Rcell ). The relationship between the output voltage and current of the cell in the Rint model is given with Eq. (21).

What is the electrochemical model of a battery?

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. Although accurate, this model is complex and needs a precise recognition of the electrochemical processes in the cell. It is not applied in power and dynamic systems studies.

How is battery capacity modeled?

For example, the battery capacity is modeled by a capacitor. Given that the voltage and internal resistance of a battery are dependent on temperature and state of charge, open circuit voltage of a battery represented by a controlled dc voltage source is changed by the state of charge and temperature.

How to model a battery based on characteristics?

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.

What are the two types of battery modeling?

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.

What is the simplest battery model?

The ideal battery model is the simplest model because the internal parameters are neglected. It is represented by only an ideal voltage source. This model is shown in Fig. 1. It is mainly suitable in some simulations where the energy released from the battery is supposed to be infinite.
