Abstract: The "Hybrid Vehicle Supercapacitor" system is an advanced energy management solution designed to enhance the performance, efficiency, and sustainability of hybrid vehicles by integrating high-capacity supercapacitors with traditional battery systems. This project leverages the rapid charge–discharge characteristics, high power density, and long lifecycle of supercapacitors to optimize power distribution during acceleration, regenerative braking, and varying load conditions. Supported by sensors, an Arduino Nano microcontroller, and power electronics such as MOSFET drivers and voltage regulators, the system ensures precise control, real-time monitoring, and seamless coordination between energy sources. The inclusion of an LCD interface, buzzer, and interactive controls further enhances usability and operational transparency. By improving energy efficiency, boosting vehicle responsiveness, and reducing strain on batteries, the proposed system contributes to extended component lifespan, enhanced user satisfaction, and reduced environmental impact—advancing the goal of sustainable and intelligent hybrid vehicle technology.
