FIELD: electricity.
SUBSTANCE: invention suggests a system of batteries providing power supply for electric vehicles, mainly rail vehicles, which is configured by means of in-series connection of a variety of battery modules wherein each battery module in the variety is configured by stacking of a variety of individual batteries. A connection contact that supplies electric energy is located between the positive electrode contact and the negative electrode contact of at least one of the multiple battery modules in order to output electric energy from at least one battery module through at least one specified connection contact having potential between the potentials of the positive and negative electrodes.
EFFECT: suggested device provides accurate adjustment of output voltage for the system of batteries within frameworks of the required range.
