Featured Application Battery management system design on lead-acid batteries with electrochemical impedance spectroscopy and first principle linear circuit model. Abstract Both the frequency domain Nyquist curve of electrochemical impedance spectroscopy (EIS) and time domain simulation of DC equivalent first principle linear circuit (FPLCDCequ) are some of the fundamentals of lead-acid batteries management system design. The Nyquist curve is used to evaluate batteries' state of health (SoH), but the curve does not distinguish charging/discharging impedances on electrode-electrolyte interfaces in the frequency domain. FPLCDCequ is used to simulate batteries' terminal electrical variables, and the circuit distinguishes charging/discharging impedances on electrode-electrolyte interfaces in the time domain. Therefore, there is no direct physical relationship between Nyquist and FPLCDCequ This paper proposes an AC equivalent first principle linear circuit (FPLCACequ) by average switch modeling, and the novel circuit distinguishes charging/discharging impedances on electrode-electrolyte interfaces in Nyquist. The novel circuit establishes a physical bridge between Nyquist and FPLCDCequ for lead-acid batteries management system design.
