The article is devoted to solving the problem of charge equalization of multi-element batteries
with rated voltage up to 1000 V, operating in dynamic modes with different charge and
discharge depth. The article proposes the method of balancing voltages of power battery
elements, which consists in forming a reference signal equivalent to the reference voltage of the
battery element for the current state of charge. Balancing circuit active control is carried out
in proportion to the actual element voltage deviation from the reference value. The proposed
method can be used both for passive balancing techniques based on ballast resistors, and for
more effi cient operation of circuits made on electromagnetic energy redistribution systems
between galvanic cells. A number of Simulink models have been developed to determine the
electrical parameters of active and passive balancing circuits. Performance and accuracy
study of balancing a multi-element battery in charge and discharge modes was conducted by
Simulink models. Compared to classical methods of cell voltage equalization, the proposed
method provides an increase in accuracy and the balancing process dynamic parameters
improvement at any value of the battery charge. The proposed methods of charge equalization
make it possible to increase the multi-element battery operation effi ciency in a wide range of
charging currents.
Keywords: multi-element battery, passive balancing of battery cells, average voltage, reference voltage.
