Abstract

The transition to electric vehicles (EVs) demands advanced energy storage systems capable of addressing the growing requirements for efficiency, reliability, and sustainability. This study presents the development of a Hybrid Energy Storage System (HESS) designed for EV battery charging, integrating lithium-ion batteries and supercapacitors. By leveraging the high energy density of lithium-ion batteries and the rapid charge-discharge capabilities of supercapacitors, the proposed HESS addresses the limitations of individual storage technologies.The hybrid system architecture optimizes energy flow, minimizes power losses, and ensures a seamless transition between energy sources. Key design aspects, including energy management strategies, control algorithms, and system integration, are discussed in detail. Experimental validation highlights significant enhancements in chargedischarge cycles, energy efficiency, and thermal stability compared to conventional battery systems. Beyond technical performance, the study evaluates the economic and environmental impacts of HESS adoption in EVs. The findings indicate reduced operational costs and lower carbon emissions, reinforcing the role of HESS in promoting sustainable transportation. The proposed solution not only extends the lifespan of EV battery systems but also supports the development of a more robust EV charging infrastructure. This work underscores the potential of HESS as a transformative approach to addressing the challenges of energy storage in electric vehicles, contributing to the advancement of cleaner, more efficient, and cost-effective transportation solutions.
