Abstract: The paper considers the model of active balancing of lithiumion batteries on flyback converters, which is almost as fast as passive balancing schemes. This model is implemented using Spice models of basic components, such as resistors, keys, etc., without specific solutions. Therefore the simulation results can be repeated using a domestic component base with resistant to space factors, which is important for spacecrafts. Active balancing circuits allow balancing voltages in lithium-ion battery more efficiently in term of energy consumption, redistributing electrical energy between all cells in the battery. The use of active balancing systems on flyback converters allows a better equalizing voltages on batteries of different capacities, which is especially important for spacecrafts at late stages of battery operation, when batteries are significantly susceptible to degradation effects, and replacing them is not possible.

Keywords: battery cells, battery pack, spacecraft, passive balancing, active balancing, modelling
