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 …
Battery equalization active methods
Passive methods can only be used for Lead-acid and Nickel-based batteries as Li-ion batteries cannot be overcharged. They can be subdivided into two subgroups: overcharge and fixed shunting resistor. In the overcharge method, when cells are fully charged, due to internal reactions cells stop being charged and the energy is …
