Numerical Model of Optimization of the Lead-acid Accumulator Grids
Eva Kadlecová, I. Behunek, Pavel Fiala · PIERS Online · 2006
This article deals with chemical processes during charging and discharging of the lead-acid accumulator. There is presented one shape of electrode grids in this work, but we researched more variants. We prepared numerical models based on the combined flnite element method (FEM) and flnite volume method (FVM) of those variants and computed current density distribution on the surface of electrodes. The model joins magnetic, electric and current flelds, ∞ow fleld and chemical nonlinear ion model. Results were obtained by means of the FEM/FVM as a main application in ANSYS software.
