Analyzing the evolution of electric vehicle charging infrastructure and its influence on global mobility

Abstract

The transportation sector is one of the major contributors to global greenhouse gas emissions due to its heavy dependence on fossil fuels such as gasoline and diesel. The anticipated depletion of these conventional energy sources, coupled with increasing environmental concerns, has accelerated the adoption of electric vehicles (EVs) as a cleaner and more sustainable alternative. As transportation systems transition from fossil-fuel-powered vehicles to low- or zero-emission mobility, the development of a reliable electric vehicle charging infrastructure (EVCI) has become a critical requirement. This study presents a comprehensive review of the key aspects of EVCI, including load management, power grid impacts, charging control strategies, fault analysis, and protection mechanisms for electric vehicle charging stations (EVCS). It further examines the current status of EV adoption, government policies promoting electric mobility, and recent advances in charging technologies and supporting infrastructure. The advantages and limitations of different charging technologies are critically analyzed, with particular emphasis on charging infrastructure and vehicle-to-grid (V2G) and grid-to-vehicle (G2V) power transfer mechanisms. Finally, the study identifies the major technical and infrastructural challenges limiting the large-scale deployment of EVs, including inadequate charging infrastructure and constraints in fleet management technologies. Based on these findings, the paper provides recommendations to enhance charging infrastructure, improve grid integration, and support the widespread adoption of electric vehicles.
