A procedure for determining the efficiency of condenser energy-storage systems that are installed in underground cars for receiving electric power for traction electric cars working in a recuperative-braking regime is proposed. It was suggested to carry out comparative analysis of the efficiency of energy-storage systems on the basis of the following parameters: index of electric-power recovery in a full start-brake cycle of the wagon operation, relative determination of electric-power recovery in the braking regime and electricpower loss in the active regime of car operation, index of electric-power recovery in electrodynamic braking of traction electric cars, and relative evaluation of the mass of energy-storage systems. It is proposed to analyze the efficiency of energy-storage systems taking into account their design features. Energy-storage systems can be manufactured in a monoblock or stepped design. The proposed procedure of comparative analysis of the energy and mass - dimensional characteristics of underground cars with energy-storage systems allow their operation to be evaluated with a minimum number of source data. Installation of energy-storage systems increases the mass and energy expenditure during wagon operation, but this loss is significantly less than the energy volume recovered with an energy-storage system in a regime of recuperative braking of traction electric cars. Energy-storage systems allow one to create effective systems of autonomic recuperative braking on underground cars. A stepped design of energy-storage systems decreases their mass-dimensional characteristics and increases energy efficiency. The only real disadvantage of energy-storage systems preventing their use is their large size.
