Abstract : The increasing demand for sustainable and eco-friendly transportation has encouraged the development of electric vehicles as an alternative to conventional fuel-powered automobiles. However, the high cost of purchasing new electric vehicles remains a major barrier for many users. This project focuses on retrofitting existing vehiclesinto electric vehicles by replacing the internal combustion system with an electric drivetrain powered by lead- acid batteries. The proposed system integrates a Battery Management System (BMS) designed to monitor voltage, current, temperature, and state of charge to ensure safe and efficient battery operation. Lead-acid batteries are selected for their affordability, reliability, and recyclability, making them suitable for cost-effective retrofitting applications. conversion process includes motor integration, controller configuration, and real-time power monitoring to optimize performance and extend battery life. This approach not only reduces vehicular emissions and fuel dependency but also promotes resource conservation by reusing existing vehicle infrastructure. The project demonstrates a practical and economical pathway toward sustainable electric mobility.
