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.
To recover the lead-acid battery, the lead sulfate is converted back to active material by inverse charging before the main stage of charging happens. All locally and fully sulfated lead-acid batteries are recoverable in this method.
Series of experiments were carried out on four lead acid batteries, batteries A, B, C and D, involving charge, discharge, OCV and recovery phases. It was noticed that the open circuit voltage of a lead acid battery after solicitation and their energy recovered after a discharge can be used to decipher how healthy a battery is.
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
Batteries use 85% of the lead produced worldwide and recycled lead represents 60% of total lead production. Lead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered.
The total charge required for recovery of a battery is about 1.5–2 times the equivalent capacitance of the battery. The recovery mode interval time contributes to the chemical reaction on the electrode surface and prevents extremely high temperatures from arising within the battery.
