Abstract

This paper presents performance improvement of old lead acid battery which usually used in car. When it is used in the long time, the efficiency is reduced. A problem is occurred because it is covered by sulfate on the surface of the lead plate electrode. This cause on current supply efficiency of the battery is decreased because resistance increases. This research presents the way to solve the problem. The sulfate must remove out of surface of the lead plate electrode. The high frequency stimulation signal generation is applied. A car battery 12 V 75 AH is experimentally tested. CCA meter model of AE300 is as a tool for efficiency observing. The high-frequency stimulation circuit at 64.7 kHz is designed. The experiments were done by applying DC voltage as a ripple high-frequency onto the electrode plates with different time intervals. The result shows that Cold Cranking Amp (CCA) value of the battery is increased. Therefore, it can be summarized that 64.7 kHz high frequency stimulation can increase the efficiency of battery.

利用高频刺激改善铅酸蓄电池性能

介绍了车用旧铅酸蓄电池的性能改进。当长时间使用时，效率会降低。出现问题是因为铅板电极表面被硫酸盐覆盖。由于电阻增大，导致电池的供电效率降低。本研究提出了解决这一问题的途径。硫酸盐必须从铅板电极表面去除。采用高频刺激信号发生器。对12 V 75 AH的汽车蓄电池进行了实验测试。AE300的CCA仪表模型作为效率观测的工具。设计了64.7 kHz的高频刺激电路。实验是通过在不同时间间隔的极板上施加直流高频纹波电压来完成的。结果表明，电池的冷启动安培(CCA)值有所提高。综上所述，64.7 kHz高频刺激可以提高电池的效率。
