Annotation: The methodology and algorithm for determining the parame- ters of a dynamic model of a lithium-ion cells are considered. The model is based on a combination of the Tevenin and Shepherd models, created to study and construct the characteristics of the charge-discharge characteristics of a lithium-ion cells. The simulation results reflect the high adequacy of the algorithm on a test example in Simulink Matlab and experimental data. The developed algorithm is used to create a simulator of a lithium-ion cells of a spacecraft.

Keywords: lithium-ion cell model, thevenin equivalent circuit, parameter calculation model
