Mathematical Modeling and Analysis of Electric Vehicle Battery

Accurate modelling of electric vehicle battery systems is essential for optimising performance, improving efficiency, and extending battery life as electric vehicles become increasingly popular as environmentally friendly transportation options. This study explores the complex field of mathematical modelling as it pertains to electric vehicle batteries. The goal is to offer a thorough summary of the different methods, obstacles, and future possibilities in this important field. The paper thoroughly analyses past developments and current battery models, explaining the transition from traditional methods to modern physics-based models. Exploring the core electrochemical mechanisms that impact battery performance, emphasising important factors like internal resistance, state of charge, and temperature effects. Examining various modelling techniques, this analysis discusses the advantages and disadvantages of each approach. The methods discussed encompass physics-based, empirical, and hybrid models. Investigating the complex interplay between electrochemistry, thermal effects, and external factors that impact battery performance is the focus of this study. The study also explores the relationship between these models and the dynamic characteristics seen in electric vehicle batteries. This study contributes to our comprehension of the mathematical modelling of batteries in electric vehicles.
