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.
In this paper, a new method of charging and repairing lead-acid batteries is proposed. Firstly, small pulse current is used to activate and protect the batteries in the initial stage; when the current approaches the optimal current curve, the phase constant current charging is used instead, when the voltage is low.
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.
In a previous study, we reported the application of pulsed-current techniques to the formation of lead/ acid battery plates. The results showed that the efficiency of the process was 15-30% greater with a pulsed- current than with an invariant-current schedule.
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.
Abstract A pulsed-current technique is evaluated for the rapid charging of lead/acid cells that are prepared with either low-antimony or lead-calcium-tin grids. For comparative purposes, these cells are subjected to repetitive reserve-capacity cycling under either pulsed-current or conventional, invariant-current recharge.
