Energy Storage Systems for Electric Vehicles: A Performance Analysis of Batteries, Fuel Cells, and Alternative Storage Systems

Abstract: The transition to electric vehicles (EVs) as a sustainable transportation solution hinge on the performance and efficiency of energy storage systems (ESSs). This paper examines the landscape of ESS technologies for EVs, evaluating their respective strengths and limitations. It begins with an overview of traditional battery technologies, including lead-acid, nickelmetal hydride (NiMH), and lithium-ion batteries, highlighting the dominance of lithium-ion and its ongoing development. The paper then explores emerging battery technologies, such as solid-state, ZEBRA, metal-air, and flow batteries, assessing their potential to overcome the limitations of current battery systems. Fuel cells, supercapacitors, superconducting magnetic energy storage (SMES) systems, flywheels, mechanical springs and Compressed air systems are also discussed as alternative or complementary ESS options. Finally, the paper addresses the growing importance of hybrid energy storage systems (HESSs), which combine multiple technologies to optimize EV performance, range, and lifespan. By analysing the diverse range of ESS options, this paper provides insights into the future of sustainable transportation and the critical role of energy storage technology.
