Concepts

TL;DR

The paper reviews existing battery models for electric vehicles and energy storage systems and proposes a strategy to mitigate high‑frequency charging and discharging currents. It presents a nonlinear state‑of‑charge‑dependent model that incorporates high‑frequency switching effects and outlines a method to reduce these currents. Simulation results are shown to agree with laboratory measurements, confirming the model’s validity.

Abstract

This paper initially presents a review of the several battery models used for electric vehicles and battery energy storage system applications. A model is discussed which takes into account the nonlinear characteristics of the battery with respect to the battery's state of charge. Comparisons between simulation and laboratory measurements are presented. The effects of high frequency switching on the battery performance are also discussed. A strategy to reduce the high frequency charging and discharging current is proposed.
