In the article, based on the features of the parametric method of controlling the electric vehicle speed (by changing the transmission ratio), the possibility of using a collector DCM as a traction motor is justified. The combination of the control method and such an engine allows one to almost halve the installed power of the traction drive, while fully meeting the requirements for dynamics and other characteristics of the modern electric car. On this basis, a method of automated conceptual design using (MS Excel) is proposed. The article provides an example of this approach application to determine the energy and kinematic parameters of the electric vehicle drive on the running platform of the Russian car “Granta." As a result of the wide-range stepless transmission use and a collector DCM with a power of only 30 kW, the machine accelerates to 100 km/h in 6 s and a maximum speed of 170 km/h, whereas in the traditional case of a transmission with a single-stage constant-ratio gearbox and an asynchronous AC motor the power of the latter (to the same machine characteristics realization) must be at least 60–70 kW. In addition, the functional scheme of the drive is extremely simplified due to the absence of the need for a voltage inverter and the direct connection of the DCM to the traction battery.
