Моделювання електроприводу електромобіля з урахуванням динамічних втрат

Abstract

The forces of motion resistance acting on an electric vehicle are considered, including gravity, aerodynamic resistance, and tire resistance. The factors influencing acceleration and speed are analyzed: traction motor power, road surface condition, vehicle aerodynamics, and total mass. A generalized system of equations is presented, taking into account inertia moments and angular velocities to determine the motor power. The efficiency of the mechanical transmission is evaluated, depending on load and speed, with analytical expressions for losses proposed. Emphasis is placed on the practical application of the model for optimizing the electric drive.
