The Effects of Charge and Discharge Behaviors Based on Lithium-ion Battery Model

More attention recently has been paid to electric vehicles (EVs) due to the characteristics of low carbon emission, quiet noise, and environmental-friendly. The battery is one of the core components for EVs which provides energy to drive the entire force system. State-of-Charge (SOC) and State-of-Health (SOH) of the battery describe how the battery works and reflect the battery model characteristic between the charge and discharge conditions. In this paper, based on the NASA datasets and the existed battery model, the effects of SOC and SOH for battery modeling are analyzed and an improved battery modeling is provided. The effectiveness of the proposed battery modeling is verified through MATLAB/SIMULINK software.
