Pedal Charger for Three‐Wheeler Battery Charging in Bangladesh

Three‐wheelers are a key mode of transportation in Bangladesh, but charging their batteries adds strain to the national grid, especially amid the country's power crisis. A pedal charger offers an eco‐friendly solution, but continuous pedaling limits its reliability for larger electrical systems. A major drawback of traditional pedal chargers is the absence of a flywheel, which could improve efficiency. This research focuses on developing a more effective pedal charger by integrating a flywheel, ensuring smoother energy generation. Experiments with varying load capacities demonstrate its performance, with an average energy output of 200 W and an efficiency of approximately 70%. The redesigned charger consistently supplies the necessary voltage and current, providing a sustainable solution for three‐wheeler battery charging. By reducing dependency on the national grid, this innovation promotes clean energy alternatives, making it particularly beneficial for countries like Bangladesh.
