What is a battery model?

An accurate and realistic battery model is essential to design an efficient battery-powered system. This special issue invites articles on state-of-the-art developments for battery modeling. We solicit original, high-quality technical papers, including review articles, which are not under consideration by other publications.

What are the most commonly used battery modeling and state estimation approaches?

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.

What is battery system modeling & state estimation?

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.

Can simple battery models be used to design a battery thermal management system?

The general conclusions of this review are as follows: Simple battery models cannot fully reflect the dynamic and electrochemical characteristics of a battery and are typically coupled with three-dimensional CFD thermal models to design, evaluate, optimize, and improve battery thermal management systems.

What is the analytical model of a battery?

The analytical models describe the battery at a higher level of abstraction than the electrochemical and electrical circuit models . These models perform well for the SOC tracking and runtime prediction under specific discharge profiles. The simplest analytical model is called Peukert’s law .

Why is battery modeling important?

Battery degradation, state of charge, and aging concerns impose boundaries on charge/discharge currents and discharge depths. Despite their relevant importance, many challenges remain unsolved as regards characterizing and managing batteries. In this respect, battery modeling plays an important role in the design and use of batteries.
