The question of the efficient recovery of braking energy is becoming increasingly important, with emphasis on improving the energy efficiency of the economy. The effectiveness of recovery in rail vehicles is limited, inter alia, by the possibility of consumption of recovered energy. One way to improve the recovery efficiency is building energy storage devices in substations, on the network and in rail vehicles. Such storage devices have to work in two modes: as a reservoir of power, compensating for the ripple current, or as a reservoir of energy, supplying vehicles for longer periods. Presently, power storage systems may be made using ultra-capacitors that have a possibility to make hundreds of thousands cycles of high current and low energy. Applications of the battery storage allows the storage of large amounts of energy, but not for high-frequent cycle. The solution to the problem are hybrid storage systems which combine the features of power and energy storage tank. They can be made on the basis of existing batteries and ultra-capacitors. The size of stored power and energy depends upon the volume designated for each part. The article explains how power and energy capacity change versus ratio of the volume destined for battery and ultracapacitor. Another solution is to use modern LTO and LIC cell, which combine features of batteries and capacitors. The article presents a comparison of the power and energy of storage systems made from these hybrid cells. Construction of a storage tank capable of storing both power and energy and for providing high number of cycles opens the way to new supplying solutions for rail vehicles like periodical charging of the vehicle storage system.
