Deteriorated Lead-acid Battery Recovery Machine

Abstract

This research paper presents the design and construction of a depleted lead-acid battery
regenerator, focusing on 12 V, 75 Ah automotive batteries in general automotive applications. By choosing
to use a Buck converter circuit to generate a PWM signal to control the desired frequency and duty cycle.
Using a frequency of 20 kHz and a high frequency pulse technique to stimulate the battery. The
experiment will discharge before and after stimulation of the battery. To analyze energy storage and
discharge by connecting to a 150 W load, the results obtained were analyzed and summarized. Before
stimulation, energy is stored at 75 Wh after stimulation Store energy at 158 Wh Battery performance
After the experiment, the efficiency was increased by 109%, in line with the objectives set by the special
project team and in line with the relevant theories. Make the battery last longer than that
