Extension of battery life via charge equalization control
The primary difficulty in charging storage batteries is in attaining process regulation that allows fast charging while avoiding destructive overcharging. A two-level approach to controlling the charging process is presented. A general background discussion of batteries and charging problems is followed by the presentation of a novel recirculating charge …

Equalization
Equalization is a process of controlled battery over-charging. It is used as a routine maintenance activity and a remedial activity for flooded lead acid batteries. It is part of the multi-stage charging process. Lead acid batteries suffer from ''sulfation''. This happens when the sulfuric acid inside the battery cells form tiny crystals on the lead …
