Electrification of Transportation (EV/HEV/EV Charging)

Abstract

The electrification of transportation has emerged as one of the most significant technological transitions of the 21st century. Increasing concerns over climate change, urban air pollution, and fossil fuel dependency have accelerated the development and adoption of Electric Vehicles (EVs), Hybrid Electric Vehicles (HEVs), and supporting EV charging infrastructure. This paper presents a comprehensive review of electrified transportation systems, including their historical evolution, working principles, battery technologies, charging methods, grid integration, and environmental impact. The study also examines challenges such as battery degradation, charging time, infrastructure cost, and grid stability. Comparative analysis between Internal Combustion Engine (ICE) vehicles, HEVs, and EVs is provided through tables and figures for better understanding. The role of renewable energy integration and smart charging strategies is also discussed. Although EV adoption is growing rapidly worldwide, several technical, economic, and policy-related challenges remain. This paper highlights current research directions and provides insight into future trends in transportation electrification.
