Abstract

Vanadium Redox Flow Battery (VRFB) is a relative new type of secondary battery that has ability as Energy Storage System (ESS) for renewable energy power plants such as solar cell. 2D VRFB single cell was modeled using COMSOL Multiphysics software and simulated numerically by using Nernst-Planck, secondary current distribution, tertiary current distribution and Buttler-Volmer principle. Simulation was conducted at 293,15 K, with electrode thickness variations of 1 mm (L1), 2 mm (L2), 3 mm (L3), 4 mm (L4) and 5 mm (L5). According to the simulation results, it is known that electrolyte potential in negative electrode is higher than positive electrode and the distribution is tend to decrease for all variations.  Surface concentration near collector is dominant during charging compare inlet position and the reverse phenomenon occur during discharging process. VRFB L1 show weak performance and VRFB L2 show the best performance in term of electrolyte potential and species molarity in the electrode surface.

Abstract

This research aims to determine the energy efficiency of lead acid batteries after testing the charge-discharge process with a constant current method. Charge-discharge current variations of 0.3 A, 0.5 A, and 0.6 A. The performance voltage range when the charging process has a value in comparison with the charging current. The greater the charging electric current can change the voltage range of the greater performance. Conversely, at the discharge process. The greater the discharge electric current can change the performance voltage range the smaller. Meanwhile, in the performance voltage range the discharge process is lower if the discharge flow gets bigger. Based on the results of the charge-discharge process test, it can be determined the energy efficiency values of the current variation of 0.3 A, 0.5 A, and 0.6 A, which are 76.32%, 76.06% and 91.33%, respectively.
