Abstract. The main transmission schemes of modern vehicles are considered, the practice of their use by large concerns as part of electric vehicles is analyzed. The possibilities and advantages of using transmissions with variable gear ratios are shown, and the main problems affecting the efficiency of an electric vehicle as a whole are highlighted. Based on results of calculations, recommendations are developed regarding the selection of the main parameters of the electric vehicle transmission, depending on the requirements and operating conditions. The recommendations are aimed at increasing the efficiency and improving the traction characteristics of an electric vehicle. In the MATLAB Simulink environment, a model evaluation of a transmission with an unfixed gear ratio as part of a vehicle with an electric power plant was performed and an analysis of the possibility of using such a transmission was carried out. A method for determining the optimal transmission parameters based on the developed vehicle model in the Simulink environment is proposed.

Keywords: electric vehicle, efficiency, transmission parameters, traction characteristics, efficiency, variable ratio transmission
