Energy storage technology and its impact in electric vehicle: Current progress and future outlook

Abstract

The desirable characteristics of an energy storage system (ESS) to fulfill the energy requirement in electric vehicles (EVs) are high specific energy, significant storage capacity, longer life cycles, high operating efficiency, and low cost. In order to advance electric transportation, it is important to identify the significant characteristics, pros and cons, new scientific developments, potential barriers, and imminent prospects of various energy storage technology. The objective of current research is to analyse and find out the optimal storage technology among different electro-chemical, chemical, electrical, mechanical, and hybrid storage system. Different batteries including lead-acid, nickel-based, lithium-ion, flow, metal-air, solid state, and ZEBRA along with their operating parameters are reviewed. The potential roles of fuel cell, ultracapacitor, flywheel and hybrid storage system technology in EVs are explored. Performance parameters of various battery system are analysed through radar based specified technique to conclude the best storage medium in electric mobility. Additionally, the current study compiles a critical analysis of 264 publications from various sources.
