锂离子电池电化学阻抗谱的荷电状态相关多项式等效电路建模

Electrochemical impedance spectroscopy (EIS) is used not only to give a thorough understanding of reaction kinetics and transport mechanisms in lithium-ion batteries (LIBs), but also to provide a promising nondestructive tool for state of charge (SOC) estimation. Although various equivalent circuit models (ECMs) have been proposed to model impedance spectra, the impact of SOC on circuit parameters...
