Modern serial electric cars are driven on the system “battery - driven inverter - motor - single-stage reduction gear”. The alternative drive system “battery - motor - driven variator - main gear” is structurally more simple and ensures better resource utilization of the traction battery in the urban operation by reducing the required engine torque (current) at low speeds. By detailed simulation of vehicles with two traction drive systems it is shown that the dynamics during acceleration-braking and energy consumption in the steady state at the “cruising” speed are almost identical. But in the main mode of real operation (in the city), the system with speed control through the variator has approximately 1.5-fold superiority both in the final run of the electric vehicle and in the current load of the battery.
