Enhancing Battery Electric Vehicle Performance Through Self-Charging Capability

Abstract

The project focuses on creating a two-passenger battery electric vehicle with a self-charging mechanism, capable of carrying up to 250 kilograms. This innovative vehicle aims to utilize wheel rotation energy for battery charging, thus reducing pollution. The team modified a golf cart-like chassis using Mild Steel C Channel material. Key components, including the alternator, motor, and DC-DC converter, were strategically positioned to harness rotational energy from the wheels, generating 12V to 14V electricity. The DC-DC converter then elevated the voltage to 54V, efficiently charging four connected batteries in series for a 48V power output. Testing verified power supply to batteries and studied travel distances with and without the self-charging system. Results confirmed the system's success in recharging batteries during operation, elevating efficiency and range. Overall, this project successfully fabricates and tests an electric vehicle with self-charging capabilities, offering an eco-friendly solution for sustainable transportation and contributing to a greener automotive future.
