Abstract

A hybrid energy storage system (HESS) comprising of battery and supercapacitor (SC) has been employed to resolve the issues faced by single storage systems used for electric vehicles (EVs) application. The battery ESS is able to provide better mileage, but unable to deliver a higher speed. Also, battery under high-stress level undergoes degradation and requires frequent replacement. Besides, SC is able to provide higher speed; however, it is unable to deliver the desired mileage to the vehicle. In order to solve it, a HESS is required. Various topologies exist in the literature, which defines the interface between the two ESS to provide optimal use of each. Based on the existing literature, this manuscript provides an overview of various topologies along with detailed comparative analysis based on cost, flexibility, control, efficiency, and size of DC/DC converter. Based on the manuscript and requirements, the selection of interfacing topology can be readily acquired.

混合动力汽车中超级电容器与电池的接口拓扑研究综述

采用一种由电池和超级电容器组成的混合储能系统(HESS)来解决电动汽车单一储能系统所面临的问题。电池ESS能够提供更好的里程，但无法提供更高的速度。此外，电池在高压力下会退化，需要经常更换。此外，SC可以提供更高的速度;然而，它无法为车辆提供所需的里程。为了解决这个问题，需要一个HESS。文献中存在各种拓扑，它们定义了两个ESS之间的接口，以提供每个ESS的最佳使用。在现有文献的基础上，本文概述了各种拓扑结构以及基于DC/DC转换器的成本，灵活性，控制，效率和尺寸的详细比较分析。根据手稿和要求，可以很容易地获得接口拓扑的选择。
