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.
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 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. Soft sulfation is removed by the method of gassing which however does not work for hard sulfation.
