Optimal Control of Fast Charging Converters for Renewable Systems in E-Vehicle Applications

Abstract

This review delves into the optimal control of fast charging converters for renewable systems in electric vehicle (EV) applications. With the rise of EVs, a robust charging infrastructure becomes imperative. Ultra-fast charging (UFC) technology emerges as a pivotal solution for medium to long-distance travels. One study introduces a smart charging station with a modular DC/DC design, distributing power across multiple charging ports. By modeling this as an optimization problem, the goal is to minimize charging time and cost, with simulations suggesting that 800 kW power can efficiently serve 10 charging spots. Another study highlights global EV technological progress, emphasizing diverse EV types and their energy management. The importance of optimizing power distribution among varied energy storage elements is discussed. The potential of wide bandgap (WBG) semiconductor technology, especially SiC devices in EVs, is underscored, detailing their characteristics and the significance of energy optimization for EV charging. Challenges with SiC modules are also explored, providing insights for future research.
