Bicycle Powered Mobile Phone Charger

The invention of electricity has become an essential part every aspect the society globally. With increasing demand for electrical appliance and electronic gadgets, this also increased consumption energy significantly. As a result, we experience power outage which causes huge losses to industries. Hence, research address if it is sustainable use alternative in form bicycle charge mobile phone. Bicycle renewable that does not require burning fossil fuel generate energy. objective study design phone charger circuit consist integration components. Subsequently, between conventional charging method pedal powered can be assessed. This analysis done determine economically solution electricity. In analysis, three selected dynamos hubs were assessed based on performance data during low, medium, high speed. relationship voltage, speed, time obtained from calculations. chosen dynamo hub was mid-range model, Shimano DH-3D72 produces sufficient at low speed next DC-DC converter topology ensure output voltage capped 5V. results have shown SEPIC designed application used. third selection ultracapacitor needed store discharge justified with relevant calculations further simulated analog software, LTSpice XVII. All components integrated complete under various inputs condition. outcome efficiency system improved by 30%. payback period would only 406 days equivalent 1.1 years.
