We investigate impedance spectra obtained from an electrochemical model using pulsed signals. We characterize the dependence of NiMH battery parameters such as electrodes porosity and conductivity on impedance. We are able to relate impedance to simulated battery aging. Impedance as a function of state of charge is also investigated. Further characterization on accuracy and resolution and results on temperature dependence will be submitted.
