Research on the voltage of Hybrid Energy Storage System in Electric Vehicles Charging

Abstract

Abstract. Integrated Magnetic structure can reduce the overall size and weight of a converter, decrease the core losses of a converter. In this paper, the aim of studying the magnetic integration technology applied to DC-DC converters of electric vehicles, is to gain further loss reduction and improve the life of an electric car battery, etc.. At the same time, adding a second-order Bessel low pass filter with integrated magnetic structure will improve filter performance and optimize the power quality of the hybrid energy storage system. Combined battery and ultra capacitor hybrid energy storage systems consist of high-capacity storage, fast response process, recovery of braking energy ,which can extend the life of the electric vehicle and ensure a rapid increase in the speed requirements. The good performance of the hybrid energy storage system in a typical driving cycle has been verified by MATLAB Simulation and experimental tests.
