Standardized and Modernized 12 Volts Mobile Electric Battery Charging Machine-An Implementation

In this research work, a standard and modernized 12 Volts battery charging machine was constructed and implemented. The materials used were locally sourced. The main objective centred at making the charger to protect the battery from being overcharged and damaged. Related works on the subject were carefully reviewed to arrive at the main objective. The best circuit option for the functionality and reliability of the charge controller was developed. The method adopted, include perforating the Veroboard for soldering and mounting of electronic components on the board. Integration of the required integrated circuit (IC), incorporation of transformer and casing. The circuit was initially tested by checking the output voltage, before testing with battery. The pulse width modulator circuit successfully produced approximately 100 Hz output frequency. The functionality of the charger controller was tested, and was found to be operating optimally, while serving and preventing the battery from breakdown and damage.
