In the ever-evolving landscape of energy storage, a recent study published in the *Journal of Neutrino: Journal of Physics and Its Applications* has shed new light on the performance dynamics of lead-acid batteries, a technology that has been a cornerstone of the energy sector for decades. The research, led by Kurriawan Budi Pranata from the Department of Physics Education at the University of PGRI Kanjuruhan Malang, delves into the intricate relationship between the state of charge (SOC) and the efficiency of three-cell lead-acid batteries, offering insights that could reshape how we approach battery management and optimization.
Lead-acid batteries, despite their age, remain a critical component in various applications, from automotive to renewable energy storage. However, their performance can vary significantly based on how they are charged and discharged. Pranata’s study aimed to unravel these nuances by subjecting the batteries to 10 cycles of charge-discharge treatments under different SOC conditions—100%, 50%, and 25%—with a discharge current of 0.8A. The results were telling.
“The 100% and 50% SOC treatments showed better performance and battery energy compared to the 25% SOC treatment,” Pranata explained. The study revealed that the voltage efficiency was highest at 88% for the 25% SOC condition, followed by 87% for 50% SOC and 84% for 100% SOC. However, capacity efficiency and energy efficiency told a different story. Capacity efficiency was highest at 84% for 100% SOC, dropping to 80% for 50% SOC and further to 69% for 25% SOC. Energy efficiency was highest at 70% for both 100% and 50% SOC, but plummeted to 62% for 25% SOC.
These findings are not just academic; they have significant commercial implications. For industries relying on lead-acid batteries, understanding the optimal SOC for charging and discharging can lead to better battery management, extended battery life, and improved overall efficiency. This could translate to cost savings and more reliable energy storage solutions, which are crucial for sectors like automotive, telecommunications, and renewable energy.
Pranata’s research suggests that maintaining a higher SOC during charging and discharging cycles can enhance battery performance. This insight could guide manufacturers and users in optimizing their battery usage, potentially leading to more efficient and cost-effective energy storage systems.
As the energy sector continues to evolve, with a growing emphasis on renewable energy and electric vehicles, the role of lead-acid batteries remains pivotal. Pranata’s study offers a timely reminder that even mature technologies like lead-acid batteries have room for optimization and innovation. By leveraging these findings, industries can make more informed decisions, ultimately contributing to a more sustainable and efficient energy future.
The study, published in the *Journal of Neutrino: Journal of Physics and Its Applications*, serves as a testament to the ongoing relevance of fundamental research in driving technological advancements. As Pranata’s work demonstrates, there is always more to learn and discover, even in the most familiar of technologies.
