A new method of establishing the state of charge of leadacid batteries with electrolyte circulation
TLDR
In this paper, an empirical law, based on results obtained from different experiments, has been developed to isolate the accumulator state of charge as a function of the maximum state-of-charge density at the test point and a proportionality constant, n.About:

Prediction of battery behaviour in SAPV applications
TL;DR: In this paper, a mathematical approach to the behavior of lead-acid storage batteries in Stand Alone Photovoltaic Power Systems (SAPV) is presented, which takes into account different aspects affecting the battery discharge and charge behaviour, such as discharge and discharge rate, battery capacity and current and power efficiency, among others.

Passivation reactions on the electrodes of a lead—acid cell
A. Winsel,U. Hullmeine,E. Voss +2 more
TL;DR: In this article, the capacity of Pb and PbO2 electrodes at high rate low temperature discharges has been investigated based on the solution/precipitation model of Vetter, where the capacity is limited by a diffusion process of the Pb2+ (PbSO4) species away from the current producing internal surface of the electrode through the lead sulphate passivation.

Battery State of Charge Determination in Photovoltaic Systems
R. Weiss,Joseph Appelbaum +1 more
TL;DR: In this paper, a new on-line method of battery state of charge determination in a working photovoltaic system is proposed based on extending the known open-circuit voltage-charge relation to the operating battery voltage charge relation and combining it with the ampere-hour accounting method for finite periods of time.
Journal ArticleDOI
Effects of electrolyte flow on the performance of lead-acid cells
TL;DR: In this paper, the authors show that charging processes in lead-acid batteries cause a typical multilayer configuration due to stratification in the electrolyte as sulphuric acid is used.
