A Method to Monitor Valve Regulated Lead Acid Cells
Abstract
The individual electrode impedance parameters and internal resistance of industrial type 120Ah-valve regulated lead acid(VRLA)cells are obtained from galvanostatic nondestructive technique.The resistive components of the cell are found to be minimum at a state of charge(SOC)value of 0.5.The study reflects that the optimum performance of VRLA cells is achieved at SOC values between 0.2 and 0.8.
Keywords: Valve-regulated lead acid cells; Impedance; State-of-charge
