Design Evaluation of Wireless Ultra-Fast Charging System and Related Thermal Management System for Electric Vehicles

Abstract

As the use of Electrical Vehicles has become a more sustainable option over the past decade, innovation is needed to make Electrical Vehicles more accessible. Fast charging is a widely used Electrical Vehicle charging method, but ultra-fast charging has been studied to a limited extent. One of the main research areas is improving loading speed and time. This paper presents a detailed implementation of the Simulink models of fast charging and ultra-fast charging, along with the associated thermal management system. All the necessary calculations and schematics and a comparison of fast charging and ultra-fast charging have been performed. The graphs between SOC (state of charge) and charging time is obtained for both the fast-charging model and the ultra-fast charging model. It is observed that the slope of the ultra-fast charging model is larger than that of the fast-charging model. Therefore, with the same charging time, the battery charges more in the ultra-fast charging model.
