Transient Techniques for Low Frequency Battery Impedance Measurements.
Abstract
A general formalism is developed for obtaining battery impedances as a function of frequency from the time response to an input current step. As an example, this technique is applied to impedance measurements for a 10-ampere hour nickel cadmium satellite cell. The impedance over the frequency range of 0.5 Hz to ten to the minus 6th power Hz is indicative of diffusion controlled cell polarization. (Author)
