Experimental Investigation of a Lead-Acid Battery Regeneration Technique for Improved Energy Efficiency

Abstract

Currently, extensive advancements have been made in battery technology. After years of study and development, researchers have been examining batteries with a primary focus on finding ways to enhance their efficiency, dependability, and lifespan. This research aims to effectively extend the lifespan of lead-acid batteries by using appropriate methodology. The investigations demonstrate that injecting electric pulses during the charging process improves battery capacity and cycle life. The enhanced efficiency is a result of the elimination of lead sulphate buildup on the battery’s electrodes. These tests ensure successful regeneration of the battery’s capacity and optimise the regeneration process. Using electric pulses during the charging process can help minimise the formation of lead sulphate on the electrodes. The proposed technique covers five cycles of charge and discharge, leading to improved battery performance with a 23% increase in the state of charge (SoC) at the end of the charge mode. Furthermore, the suggested method enhances battery performance by elevating the recovered charge capacity from 60% to an impressive 90%. Extensive tests and experiments have confirmed the accuracy of these findings. Consequently, the improved lead-acid battery has a remarkable efficiency improvement of approximately 34%, making it useful and highly practical.
