Sustainable Energy Harvesting Technology for E-Bicycle

This project introduces an innovative approach to sustainable energy harvesting for electric bicycles (E-bicycles) by incorporating renewable energy sources and advanced control mechanisms. The design leverages a photovoltaic (PV) system integrated with a quadratic boost converter and a Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) algorithm to maximize solar energy utilization. Energy management is further enhanced with a bidirectional DC-DC converter, facilitating efficient energy flow between a super capacitor for transient power needs and a battery system for long-term storage. The propulsion system is powered by a Brushless DC (BLDC) motor, which is driven by a three-phase voltage source inverter (VSI) for precise torque control and superior efficiency. A dynamo system supports regenerative braking, converting kinetic energy into electrical energy that recharges the battery and super capacitor. Proportional-Integral (PI) controllers are employed to maintain consistent regulation of speed, voltage, and current, ensuring stable and efficient operation. This integrated system offers a comprehensive solution for sustainable transportation by reducing dependence on fossil fuels and enhancing overall performance. It exemplifies the potential of combining renewable energy technologies with advanced power electronics and control systems to meet modern transportation needs while promoting environmental sustainability.
