In today's world, concerns about climate change and rising fuel prices have led to increased interest in electric vehicles (EVs), particularly in personal transportation. While EVs offer a clean and eco-friendly solution, they face a significant challenge – limited range. Expanding the vehicle's range is not as simple as increasing the battery size, as it adds weight and reduces overall efficiency. To address this limitation and make electric vehicles a more reliable alternative to traditional Internal Combustion Engine (ICE) vehicles, fast charging technology plays a crucial role. This project focuses on designing and analysing a Dual Active Bridge Isolated Bidirectional DC-DC Converter (DAB IBDC) specifically tailored for Extreme Fast Charging (XFC) applications in Electric Vehicles. The proposed converter employs three unique phase shift configurations single phase shift, extended phase shift, and dual phase shift. These configurations are strategically chosen to optimize the charging process and enhance the performance of high-power EV charging systems. The DAB IBDC architecture, known for its bidirectional power flow capabilities and galvanic isolation features, is utilized to meet the demanding requirements of Extreme Fast Charging. Through detailed simulation, each phase shift configuration is systematically evaluated for its impact on converter efficiency, power quality, and overall system stability. The goal is to overcome the challenges posed by limited EV range and eliminate range anxiety by developing an efficient and reliable Extreme Fast Charging solution. There are many existing state of art techniques are implemented for EV fast charging but proposed method provides more efficient solution for EV fast charging.
