Electric Vehicle (EV) Powertrain Modeling and Optimization

Abstract

The electric vehicle power train is consisting of subsystems, for the power transmission of electric vehicles (EV). This paper provides comparative study about EV powertrain subsystems and their modeling. The subsystem has components like motors, accumulators, and gear drives. Selection of proper components to be used in an EV has specific criteria depending on vehicle dynamics and drive type. EV modeling and optimization are very important aspects while working with electric vehicles. Stability of the system and performance of DC motor and electric vehicle subsystems can easily analyze by modeling and optimization. The proposed system model is simulated and developed in Scilab X-cos and MATLAB. The simulation model is described in this paper to elaborate powertrain modeling technique for EV. The results obtained from the powertrain simulation give various electrical and mechanical parameters as discussed in this paper. This paper also provides a brief study about powertrain optimization which is a very important aspect in powertrain modeling for effective sustainable mobility. The optimization of EV powertrain consists of power prediction, energy prediction, and lifecycle analysis with the consideration of efficiency region of specific subsystem.
