INTELLIGENT POWER ELECTRONIC MODULE SHARING STRATEGY FOR FAST ELECTRIC VEHICLE CHARGING SYSTEMS

Abstract

With the surge in electric vehicle (EV) adoption, there is a growing need for efficient and intelligent charging infrastructure that can handle simultaneous charging of multiple vehicles and provide fast charging speeds. In conventional multi-port fast charging stations, the Power Electronic Modules (PEMs) are usually fixed to one charging port, leading to low resource utilization, long charging time, and low charging capacity utilization. To over come these limitations, this project proposes an Intelligent Adaptive Energy Management and Power Electronic Module Sharing Technique for Multi-Port Fast Electric Vehicle Charging Stations. The proposed system will increase the utilization of charging stations, improve charging efficiency and shorten charging time by dynamically allocating power and intelligently managing energy. The charging architecture is composed of charging ports, Power Electronic Modules (PEMs), AC-DC and DC-DC power converter, communication networks and an adaptive energy management controller. The proposed controller constantly checks the charging needs, battery status, and power sources. The system can dynamically move idle PEMs from less busy charging locations to charging locations that need more power to meet demand in real time. The innovative module sharing mechanism optimises the use of charging resources and allows for efficient power distribution among the linked electric vehicles. Modeling and analysis of the proposed system is done using MATLAB/Simulink under different charging conditions. The simulation results show that the charging station utilization, charging speed, energy efficiency, and power-sharing flexibility can be significantly improved with the proposed charging system compared to conventional charging systems. The adaptive management approach also minimizes the need for idle converters and enhances the overall system reliability. This proposed intelligent charging framework offers a scalable, cost-effective, and high-performance solution for the future smart charging stations, capable of catering to the increasing trend of sustainable electric transportation and smart energy management technologies.
