Series and Parallel Hybrid Transmission in Electrical Vehicle Using Matlab/Simulink

Abstract

A hybrid electric vehicle (HEV) combines the strengths of ICE vehicles with EVs to provide a more versatile and convenient driving experience. Because it combines series and parallel architectures, the series-parallel hybrid has the best qualities of each and can function in more ways than any architecture can on its own. This paper uses Matlab/Simlunk to create a series-parallel HEV model that includes simulations of the vehicle's longitudinal dynamics, tyres, an internal combustion engine (ICE), batteries, a DC/DC converter, motor and generator drives, a speed coupling device (planetary gear mechanism), and a torque coupler. Poor fuel economy and pollution are problems plaguing conventional vehicles powered by internal combustion engines (ICEs) due to factors like inefficient hydraulic transmission in urban stop-and-go driving and a mismatch between engine fuel efficiency characteristics and the real operation requirement. The HEV control system is described. Furthermore, the efficiency of the HEV model is confirmed by simulation results.
