In conclusion, sulfation is a common issue that affects lead-acid batteries. It occurs when the battery is left in a discharged state for an extended period, causing the lead sulfate to harden and become insoluble. This results in a significant reduction in the battery’s capacity and lifespan.
Sulfation problem is solved in a battery by maintaining proper charging and discharging control of the battery. And the projected method is designed and tested through the utilisation of the MATLAB platform. The comparison examination of the proposed model is tested with experimental test data of lead-acid battery in HEV.
Sulfation is a major cause of decreased battery capacity in lead-acid batteries. When lead sulfate crystals build up on the battery plates, they create a barrier that prevents the battery from holding a charge. This buildup reduces the active surface area of the electrodes, which in turn reduces the amount of energy the battery can store.
The ultra-capacitor is coupled with the battery to solve the sulfation problem in a lead-acid battery. The ultra-capacitor is storing power through negative and positive charges of physical separation design. The energy is stored in ultra-capacitors; these positive and negative charges are separated with the help of an insulator.
In this case the natural self-discharge completely discharges the battery. This is rarely the case in commercial and passenger vehicle applications. The result of this hydration condition is that lead sulfate is dissolved as lead solubility increases considerably in the low specific gravity electrolyte.
The resistance values are increased, which decreases the voltage level of the battery, and the SOC value becomes 100%. Compared to existing methods, the proposed method provides the best maintenance of resistance value of lead-acid battery which avoids sulfation problem in HEV. 5.1.
