Effect of Pulse Charging in Lead acid Batteries Used in Electric Vehicles of Nepal The major factor in reducing the life of the lead acid battery is sulfation. Sulfation forms a layer of Lead Sulphate crystal in the electrodes making it less conductive or even blocking the electrical current to pass through it.
Lead Acid batteries simply dissolve the lead and release a voltage. Charging a lead acid battery will stop the lead-acid re-action. Charging a lead acid battery will not cause the lead to Re-Bond to the surface of the lead element.
Basically, ignore the fact that it is pulsing. Each pulse must have its voltage and/or current limited in the same way for a continuous charge. So the simplest way of charging a lead acid battery is to limit the charging voltage to approximately 13.8v for a 12v battery, although this may vary depending on the manufacturer, temperature etc.
Flooded lead acid batteries are full at 12.7V and empty at 11.5V. Charging at more than 0.5V over the full charge "on the charger" is unnecessary and damages them. Each cell is about 2.1V and charging at 2.25V and watching the battery itself does not go over 2.1v is the way to go. Multiply by 6 for a 12V battery.
The method of the research is experimental in which different patterns and relations found between the parameters of the battery are analyzed. The basic tests performed included the pulse charging of flooded and VRLA type lead acid batteries in various frequencies with the maximum of 2.5 MHz.
The electrolyte in the lead acid battery is dilute Sulfuric acid. H2SO4 is heavy than water and pure H2SO4 has specific gravity of 1.7 but the one used in the battery has the specific gravity of 1.3. Hydrometer is the instrument used in measuring the specific gravity of the electrolyte.
BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.

Pulse Charging
Battery voltage during the pulse is monitored. Once it reaches gassing voltage, the pulse current is interrupted. Thus, such pulse charging might reduce gassing. On the contrary, in comparison with equivalent average CC, pulse current generates higher joule losses and longer charging time at the same maximal current rate. Pulse charging has no influence on diffusion; however, it …
