Abstract

The growing adoption of electric vehicles (EVs) and the potential of Vehicle-to-Grid (V2G) technology underscore the importance of efficient and reliable isolated bidirectional DC-DC converters in EV charging systems. The market for electric vehicles (EVs) is expanding at an exponential rate due to the worldwide trend towards sustainable transportation, with electric mobility emerging as a crucial way to lower carbon emissions and rely less on fossil fuels. This review examines the current state and advancements of isolated bidirectional converters, specifically highlighting flyback converter topology in the context of EV charging and V2G applications. Beginning with the operating principles and advantages of isolation in bidirectional power transfer, the paper analyzes recent trends, including innovations in efficiency, compact design, and sophisticated control techniques. Key implementation challenges such as thermal management, regulatory compliance, and cost considerations are addressed, with an emphasis on their impact on scalability. The review also explores promising future directions, such as the integration of AI-driven control strategies, compatibility with smart grids, and the use of wide-band gap materials like GaN and SiC to enhance converter performance and support high-speed charging. This article aims to provide a comprehensive overview of isolated bidirectional converters’ role in advancing EV charging infrastructure and strengthening the integration of renewable energy sources within the grid.

Keywords: Electric Vehicles, BESS, Grid Frequency Regulation, Autonomous Control, Power Grid Stability.
