Hybrid energy storage systems in electric vehicle

The goal of this paper is to analyze the performance of regenerative energy storage systems (ESS) in electric vehicles. This article presents a comparison of two different hybrid ESSs and using the Li-ion based conventional battery packs. The hybrid ESSs considered in this study combine Li-ion cells with ultra capacitors and hydraulic systems respectively. The configuration of each of these combinations is presented in this document in detail. Performance of all three ESSs for drive cycles has been compared using the Autonomie software.
