Caracterización, modelación y comparación de baterías empleadas en electromovilidad en base a su carga y descarga

Abstract

In this article, the characterization, modeling and comparison of three electric batteries used in electromobility are carried out: Lithium-ion, Lead Acid and Nickel Metal Hydride; in order to determine which is the most efficient, based on the data obtained in the estimation of the state of charge. To estimate the state of clyharge, the battery uses the Thevenin equivalent circuit model and the Coulomb Amp Counting algorithm for the characterization and modeling of electrical parameters, which will help estimate the state of charge of the battery. When performing the simulation of the electrical parameters, the data obtained indicate that the most efficient battery is the Lithium-Ion battery, since it has better performance in the state of charge, compared to the other batteries analyzed; while the lead acid battery is the least efficient, in both scenarios, charge and in the discharge, presenting a deep discharge.
