This article reviews the most popular energy storage technologies and hybrid energy storage systems. With the dynamic development of the sector of renewable energy sources, it has become necessary to design and implement solutions that enable the maximum use of the energy obtained; for this purpose, an energy storage device is suggested. The most popular methods of electric energy storage are described, with an indication of the features of each technology, along with the presentation of the advantages and disadvantages of a given storage reservoir. Next, hybrid energy storage systems are presented along with their suggested applications and advantages resulting from the hybridization of technologically diverse energy storage systems.

The article discusses the results of research on the efficiency of a battery assembled with lithium-iron-phosphate (LiFeP04) cells when managed by an active Battery Management System (BMS) using the “battery-to-cell” energy transfer. This arrangement was especially developed by the authors and is intended for use in a selected suspended mining vehicle. The main emphasis was placed on variation of the two most important factors limiting in practice the effective use of a selected battery: a battery heating during operation and its voltage (power) fade over time. The advantage of the active BMS developed using the “battery-to-cell” energy transfer was compared both with the active BMS based on the cell-to-battery method and with the passive BMS as well. Particular attention was paid to the performance of the BMS balancing effect during the simulated unequal discharging of randomly selected cells (from 12 % to about 40 % of all cells number in the battery). The results obtained allowed for the formulation of appropriate conclusions and practical recommendations.
