The mathematical model of a battery supercapacitor hybrid energy storage with a DC-DC converter that considers the component's parasitic parameters and variations of the component parameters within the tolerance region has been proposed. The simplified mathematical model of the battery supercapacitor energy storage with DC-DC converter, which due to reducing the number of passive components of the topology allows reducing differential equation's system order and simplifies the analysis of the system accordingly. The method of regulator synthesis based on Kharitonov's method, which considered the tolerance parameters of the components and allows to analyze the of the system's stability in a certain range of allowable values of the model parameters has been improved. The voltage equalization system of the supercapacitor module cell of hybrid energy storage, due to utilizing a DC converter allows providing the necessary values of the accuracy of cells voltages equalization of the module during pulse current consumption has been proposed. The theoretical results could be practically applicable.
