Exploring review of advancements in fast-charging techniques and infrastructure for electric vehicles revolution

Abstract

The rapid growth of the electric vehicle (EV) industry has increased the demand for efficient and reliable fast‐charging infrastructure. This paper comprehensively reviews advancements in fast‐charging techniques, focusing on DC fast charging, evolving standards, and charging modes. A detailed analysis of on‐board and off‐board EV chargers is presented, including DCDC conversion stages with a comparison of isolated and non‐isolated topologies. Key control strategies, such as voltage and current regulation and AI‐driven approaches, are examined to optimize performance and reliability. Thermal management strategies using advanced sensors to enhance safety and battery longevity are also discussed. This paper highlights recent research contributions and emerging challenges, with insights into infrastructure development, energy storage integration, and policy implications. Notably, projections indicate that global EV sales could rise to 35% by 2030, with fast‐charging infrastructure supporting charging times as low as 15 min for 80% battery capacity. Advancements in bidirectional charging and AI‐driven optimization are shaping the next generation of smart EV charging stations. This review serves as a valuable resource for researchers, engineers, and policymakers engaged in EV technology and infrastructure development.
