This paper explores the design and analytic considerations in high- performance electric vehicle models where the EV powertrain design, estimation, and testing are the analytical. This paper describes the design and advanced evolution process of the electric vehicles, which includes modeling, calculation and testing of real-world problem in modern electric vehicle systems and comprehensive estimation of research results. While Electric vehicles powertrain simulation is more important for devolving the more efficient design, using these tests in real vehicles is necessary to improve overall vehicle design, reliability, performance, and speed. This paper contains simulation and modeling design of EV powertrain using Simulink software for MATLAB and corroborate the simulation results of the real vehicle measured at load. Integration of these simulation models with real-world data. That suggests a way to quickly design and test the performance of electric vehicles at low running cost; this paper includes good information on how to use predictive techniques and research about the electric vehicles.
