N2 - The paper examines the modeling of a reconfigurable battery pack and analyzes energy dissipation in battery energy storage across various operation modes. A battery management system is designed for the reconfigurable battery pack to minimize inner resistance and enhance energy performance across a wide voltage range. Additionally, a method for evaluating the inner resistance of reconfigurable battery packs is presented, allowing comparison with standard battery packs of the same cell number and capacity. It is shown that different battery energy storage structures in electric drive operations optimize losses in the battery pack and enable comparison of battery cell heating power during drive operations. Obtaibed results facilitate the optimization of energy efficiency and battery heating, enabling the synthesis of the electrical structure while excluding unnecessary switched states during reconfigurable battery pack operations. It is also shown that within the analyzed voltage and current range, it is possible to determine the optimal structure on the basis of the known battery pack structure and resistance ratio of the switch and battery cell.
