This paper presents a systematic review of the most commonly used battery modeling and state estimation approaches for BMSs. The models include the physics-based electrochemical models, the integral and fractional order equivalent circuit models, and data-driven models.
The basic theory and application methods of battery system modeling and state estimation are reviewed systematically. The most commonly used battery models including the physics-based electrochemical models, the integral and fractional-order equivalent circuit models, and the data-driven models are compared and discussed.
The general approach for modelling involves development of COM and validation of models. are shown in Figure 1. Rincorn Mora applied a simple electrical model to capture the dynamic battery characteristics from open circuit voltage and current. However, when the model dealt in this work is intuitive and ignored self-discharge effects [ 37 ].
Battery modeling is an excellent way to predict and optimize some batteries’ basic parameters like state of charge, battery lifetime and charge/discharge characteristic. Over the years, many different types of battery models have been developed for different application areas.
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.
To model a battery, the internal circuit parameters need to be estimated. Estimation of these parameters is difficult due to their non-linear behaviour. The battery modelling (BM) problem is a constrained, multi-dimensional, mixed variable, non-convex, non-linear optimisation problem.
