“PEV”, a software to estimate the power and torque requirements and evaluate the performance of electric vehicles

Software to estimate the power and torque requirements and evaluate the performance of electric vehicles is presented in this paper. Inertia resistance forces, road gradient forces and aerodynamic drag forces are computed from the basic laws of mechanics, whereas for the computation of rolling resistance forces the program disposes of three different models, of variable complexity, to be used according to the needs and the available data. The program also gives the user the possibility to compute the energy consumption, when a specific driving cycle is selected and so permits comparisons between different electric vehicles
