Modeling Lead-Acid Battery Operation in Renewable Energy Systems.I.Modeling Lead-Acid Battery

摘要

Models of lead-acid cell are reviewed.Mathematical models developed by various authors are presented.The reviewed models can be used to predict the profile of acid concentration,overpotential and porosity of solid matrix of electrod plates as function of time.The lead-acid cell simulation with these models is a source of data supply for lead-acid cell optimization:electrode and separator thicknesses,plates distance,but not for the optimization of systems with lead-acid battery as energy storage unit.In the second part of this paper,phenomenological models of lead-acid battery and an improved model for lead-acid battery acting as energy storage unit in stand-alone renewable energy systems will be presented.
