Description
Summary:In this paper, the electrical characteristics of a carbon enhanced valve-regulated lead-acid (VRLA) battery from East Penn Manufacturing are investigated and a dynamic model is developed for use in electrical simulations. The electrochemical processes that cause specific dynamic behaviors have been investigated. These processes are explained and a non-linear electric model, which captures the results of some of these electrochemical dynamics, is presented. The method to determine model parameters using experimental data is shown. To verify the battery model, both a pulsed current profile and an arbitrary current profile were applied to the battery and to the battery model and the voltage responses of the two were compared.
