Abstract
This paper analyzes the Electrochemical Impedance Spectroscopy (EIS) of a lithium-ion (Li-ion) bat-tery cell under different load conditions and explores the corresponding equivalent circuit. The results analyze the EIS spectra at different State of Charge (SoC) levels and illustrate the changes in the electrical parameters. This study highlights the variations occurring during Li-ion battery discharge, which can serve as a basis for real-time EIS monitoring.
