This paper focuses on the use of solar energy as a power source in a battery charging system. It becomes very difficult for us to find a source of power to charge the battery after running out of energy especially being outside. As a result, charging the battery with a solar-powered battery charger would be more practical. The system evaluates the control performance for the battery chargers in terms of voltage, current, and power output from solar power. A 24V 12W solar panel is used to power a battery that has a 15Ah 24V charging output. This project method uses the MPPT boost device charge controller. However, this project uses perturb and observe method to restore battery energy capacity to maximum capacity after recharged. Because it is used to charge a 24V, 15 Ah lead acid battery, it is designed for an input voltage of 24V and an output voltage of 26.4V. Based on the results of the battery charging system simulation, the output voltage of the DC-DC boost converter can be kept around 26.4V. The charging time needed by battery to be fully charging condition is 18000 seconds or 5 hours. For future work, the system can be achieved by performing MPPT using the Simulink model instead of putting code in the Embedded MATLAB function or solar radiation and temperature can be supplied as variable inputs in the Simulink model instead of constant values due to environmental changes.
