Implementation of Solar Panels on the Roof of the Bio Hybrid Obhi-Mec Vehicle for Battery Charging

Abstract

The limited availability of charging infrastructure for electric vehicles has driven innovation in the use of renewable energy sources, one of which is solar power. This study aims to analyze the effectiveness of solar panels as an auxiliary energy source for charging the battery of the Obhi-Mec bio-hybrid electric vehicle. The system utilized includes six 100 Wp monocrystalline solar panels, a Maximum Power Point Tracking (MPPT) solar charge controller (SCC), a 48V 30Ah battery, and a 48V 1000W BLDC motor. Testing was conducted in a static condition over a three-day period between 09:00 and 16:00 WITA to obtain data on voltage, current, temperature, and solar irradiance. The results indicate that the solar panel system generated a peak power output of approximately 304.2 Watts, with an average voltage output of ±48.91 Volts and current of ±2.22 Amperes. Charging efficiency was significantly influenced by time of day, light intensity, and ambient temperature. The implementation of solar panels proved effective in extending motor operation duration and reducing dependency on external charging sources. This research contributes to the advancement of environmentally friendly vehicle technology and offers a practical solution for electric vehicle charging in areas with limited infrastructure.
