The possibility of using autonomous motion of an electric vehicle (EV) in parts of its route that lack a source of electric power is considered. In this case, supply of energy to the EV traction motor should be carried out from a supplementary accumulator. With the aim of being able to appropriately select power plant components, experimental studies of EV motion regimes were carried out under real traffic conditions. The obtained experimental results have been systematized and processed, and major features of EV motion have been determined. Statistical methods were used to select elements of the power plant. It has been shown that EV motion regimes are characterized by irregular power consumption from a power source. In order to eliminate this problem, it was proposed to use onboard accumulators of power that can balance the irregularity of power consumption. Electrochemical double-layer capacitors can be used as such accumulators. The use of electrochemical capacitors as a buffer power source under appropriate control will make it possible to improve the conditions of operation of an accumulator battery and increase run time of an autonomous vehicle.
