Impedance parameters and the state-of-charge. II. Lead-acid battery
TLDR
In this article, it was shown that the internal impedance of a lead-acid battery is controlled by charge transfer and diffusion processes in the frequency range 15-100 Hz. But this was based on a uniform transmission line analog equivalent circuit for the battery electrodes.Abstract:
The determination of the state-of-charge of the lead-acid battery has been examined from the viewpoint of internal impedance. It is shown that the impedance is controlled by charge transfer and to a smaller extent by diffusion processes in the frequency range 15–100 Hz. The equivalent series/parallel capacitance as well as the a.c. phase-shift show a parabolic dependence upon the state-of-charge, with a maximum or minimum at 50% charge. These results are explained on the basis of a uniform transmission-line analog equivalent circuit for the battery electrodes.read more
