An improvement on empirical modelling of the batteries

Abstract

Batteries are devices that convert chemical energy contained in its active materials into electric energy throughout electrochemical red-ox reactions. Theoretically, the energy provided by a battery depends only on its active substances. Practically, just a part of a battery's capacity can be used, due to the nonreactive substances that add up to the process and which influence the magnitude of the charge-transfer reaction, diffusion rates and energy losses. In this paper five methods for modeling the batteries were presented, and one improved empirical model was implemented. The empirical model was built using Mathcad and was validated through the comparison of the experimental obtained characteristics with the ones given by the producer.
