Impedance of valve-regulated lead-acid batteries is analysed in this paper, using a model-based method. Both double-layer impedance and electrochemical reaction impedance are evaluated, using current, voltage and temperature data measured in experiments. It is shown that the electrochemical impedance is a sensitive indicator that can be utilised to detect small inequalities between batteries while the double-layer impedance is less sensitive.
