It was demonstrated that the magnitudes of open circuit voltage and energy recovery of lead acid battery have relationships with the health status of the battery which if well exploited, can lead to innovations in the science of state of health determination for lead acid batteries.
The end of life is usually considered when the battery capacity drops to 80% of the initial value. For most lead–acid batteries, the capacity drops to 80% between 300 and 500 cycles. Lead–acid battery cycle life is a complex function of battery depth of discharge, temperature, average state of charge, cycle frequency, charging methods, and time.
Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.
The batteries were chosen to be kept at open circuit voltage for 800 min because some works have shown that for lead acid batteries, the state of charge can be derived at open circuit voltage when the battery is disconnected from the load for at least two hours and this OCV is linearly proportional to the Depth of Discharge (DOD) .
Determining the state of health of lead acid batteries is complex and expensive. The open circuit voltage of batteries and their energy recovery ability were exploited. Higher energy recovery capabilities for batteries indicated better state of health. Higher open circuit voltage decrease indicated a bad state of health. 1. Introduction
Electrode potentials and cell voltage for a typical flooded lead–acid battery As charging proceeds, the potentials keep gradually increasing until end of charge is reached. At this point, all lead sulfate is converted to lead on the negative electrode and to lead dioxide on the positive; and the charge is complete.
