This study focuses on the development of dynamic battery models for EV applications. The models are based on the second-order ECM technique and developed using the Modelica language for four different types of Li-ion cell chemistry commonly found in commercial EVs. The thermal behavior of the battery at the cell level is also considered.
The battery models including the physics-based electrochemical models, the integral and fractional-order equivalent circuit models, and the data-driven models were summarized.
In terms of battery model research, the battery model required to be established has a good consistency with the external characteristics of the battery. The internal chemical reaction of the battery is a complex non-linear process.
An accurate and appropriate power battery model can effectively reflect the correspondence between the external parameters of the battery and the internal state of the battery, and simplify and specify the SOC estimation problem. It is very important for the simulation, design and optimization of electric vehicles.
The state space model is based on the battery model to establish the system state space expression, and the battery SOC is used as one of the state variables, and then the battery SOC is estimated through the filter or observer [ 94 ]. The main idea is to link the measured current, voltage, temperature and other variables with the battery SOC.
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.
