Modelling and Control of a Multi-input Converter Based EV Charging Station

– Due to their limited on-board battery capacity and status as environmentally friendly vehicles, the rising popularity of electrical vehicles (EVs) creates a pressing demand for widely dispersed charging stations. Fast charging stations, especially super-fast charging stations, can put a strain on the electrical grid by potentially overloading it during peak hours, creating an abrupt power gap, and causing voltage sags. Due to the daily charging demand being met by adequate daytime PV generation, the impact on the power system is decreased. Simulation outcomes are shown to support the advantages of this suggested multiport EV charging circuits with the PV-BES configuration in various modes. To further increase efficiency, SiC devices are added to the EV charging station. Power losses and efficiency are examined for various modes and functions and compared in simulation with customary Si device-based charging circuits
