Experimental Study of a Pack of Supercapacitors Used in Electric Vehicles

Abstract

Electric vehicles have recently attracted research interest. An electric vehicle is composed of two energy sources, such as fuel cells and ultracapacitors, which are employed to provide, respectively, the steady-state and transient power demanded by the vehicle. A bidirectional DC-DC converter is needed to interface the ultracapacitor to a DC bus. The pack of ultracapacitor consists of many cells in series and possibly also in parallel. In this regard, this paper introduces a comparative study between two packs of supercapacitors. The first supercapacitor pack is composed of ten cells in series but the second supercapacitor pack is composed of five cells in series and two parallel circuits. Each cell is characterized by 2.5 V and 100 F. A number of practical tests are presented.

A light-fostered supercapacitor performance of multi-layered ReS2 grown on conducting substrates

“…Light sensitive direct band gap semiconductor materials with energy storage capacity are of great importance for such light tunable supercapacitor performances. While energy storage devices have gained enormous attention by researchers for various applications like e-vehicles and portable electronic devices [13][14][15][16][17][18][19][20][21] , the development of smart supercapacitors are in its infant stage. In particular, supercapacitors having high cyclic stability and high power density 22,23 with ability to tune their charge-discharge characteristics are of great significance for smart energy storage technologies.…”

Experimental design for an enhanced parametric modeling of supercapacitor equivalent circuit model

“…Nonetheless, the SC terminal voltage would be influenced by numerous elements, To viably assess the SCs terminal voltage and accomplish the exact control for the SCs in the ESSs, it is pivotal to build up a precise model for the SC [3]. Displaying of SCs has happened to greatest significance when planning and dimensioning SC establishments since it is the best approach to know ahead of time about the conduct and execution of the vitality energy storage devices when applied to specific hybridization [19].…”

Social Impact on Hybrid and Retrofitted Three-Wheelers

“…Many researchers have presented design, analysis, and simulation of retrofitted vehicles and have come up with many major aspects in it [12]- [15]. The use of a supercapacitor is the latest addition in it [16]. Many researchers have tried micro-hybrid and mild hybrid designs of electric three-wheeler considering only energy aspects [17] [18].…”
