AbstractŠCharge equalization is an important part of the charge process for series-connected battery cells. This paper reviews battery behavior and performance related to the equalization problem, in the context of vavle-regulated lead-acid batteries.
The equalization voltage for the wet cell battery should be between 13.8V and 14.6V while that of the Gel Cell or AGM batteries should be between 10 V and 12 V The lead acid battery equalization voltage is the voltage that must be applied to a lead acid battery in order to equalize the cell voltages and prevent over-discharge.
Recent research trend of equalizers for battery cells equalization are explained. Four distinctive battery cells voltage equalizer circuits are simulated utilizing MATLAB/Simulink and compared. Recently, the use of electric batteries has reached great heights due to the invention of electric vehicles (EVs).
Transferring the energy from the first cell to the last cell takes a long time especially for long battery string, and has high current stress. Fast equalization speed, can use pack-to-cell and cell-to-pack topologies, and low magnetic loss due to the use of single winding.
... lead-acid battery, a voltage is produced when reaction occurs between the lead electrodes and sulfuric acid and water electrolytes . The schematic view of lead-acid battery is depicted in Figure 2.
The Equalizer is a small device that actively equalizes the voltage between battery packs. When it detects a voltage difference between different battery Cells, it kicks in and actively transfers energy from the battery with the higher voltage to the battery with the slightly lower voltage.
