TL;DR

The paper reviews battery models for electric vehicles and energy storage systems, introduces a non‑linear state‑of‑charge model, and proposes a strategy to reduce high‑frequency charging and discharging currents. The authors analyze battery behavior by reviewing existing models, presenting a non‑linear SOC‑dependent model, examining high‑frequency switching effects, and outlining a reduction strategy for charging/discharging currents. Simulation results are compared with laboratory measurements to validate the proposed model.

Abstract

This paper will initially present a review of the several battery models used for Electric Vehicles and Battery Energy Storage System applications. A model will be discussed which takes into account the non-linear characteristics of the battery with respect to the battery's state of charge. Comparisons between simulation and laboratory measurements will be presented. The effects of high frequency switching on the battery performance will also be discussed. A strategy to reduce the high frequency charging and discharging curre'nt will be proposed.
