This research addresses key challenges in electric vehicle (EV) charging infrastructure, focusing on Extreme Fast Charging (XFC) technology. The goal is to enhance battery management and integrate an active thermal control (ATC) strategy within DC-DC converters designed for XFC. The project involves developing a modified five-level LLC resonant boost DC-DC converter capable of handling over 350kW and 400A, aiming to improve charging efficiency and reliability for Malaysia`s growing EV market.

The research emphasizes designing a high-efficiency, reliable DC-DC converter and incorporating ATC to maintain safe thermal limits. It will evaluate the impact of XFC on user convenience, compare the proposed system`s performance with existing models, and highlight the unique advantages of the modified converter. This project is crucial for Malaysia, where increased EV adoption demands faster charging and improved infrastructure reliability. Expected outcomes include reduced charging times, enhanced user convenience, and cost reductions, supporting emission-free operations.
