Fast Charging of Batteries Utilized in Electric Vehicle by using Cuk Converter

This research paper proposes bidirectional Cuk converter topology with a battery management system (BMS) consisting of a Li-ion battery as the main battery and a lead-acid battery as an auxiliary, to overcome the limited driving cycle and protected charging process concerns of EV battery storage. The proposed topology utilizes Cuk converter for power sharing in different scenarios and is simulated in MATLAB/SIMULINK and tested in hardware prototype. In addition, this study presents the design and development of an Cuk converter-based EV battery charger that offers a low-cost, high-power-densitybased charging solution with high efficiency and power factor. The proposed charger has fewer components functioning during a single switching cycle, resulting in decreased conduction losses and improved efficiency. A flyback converter synchronizes the orders for constant current and constant voltage charging, and the overall harmonic distortion in the supply current The proposed EV battery storage and charging solutions have significant potential in addressing the challenges faced by EVs in terms of limited driving cycle and protected charging process. The results of this study demonstrate the improved efficiency, power density, and charging performance of the proposed solutions under different operational conditions, which can contribute to the development of more efficient and cost-effective EVs.
