The Study on the Battery Modeling through the Mathematical Modeling Techniques of High-power Lithium-Polymer Battery for HEV

摘要

This paper proposes the battery mathematical for modeling HEV (Hybrid Electrical Vehicle) high-power lithium-polymer battery. The nonlinear characteristics of Lithium Battery are expressed by the state equation. The battery parameters are obtained by the least square method to minimize errors using charge and discharge driving cycle data. The proposed method is verified by the battery cycler.
