Inception of electromechanical bike incorporating torque sensor technology and solar charging kit

Abstract

Bicycles are one of the most efficient methods of travelling in Bangladesh, given the country’s narrow roads and heavy traffic. Pollution, and load-shedding are also two problems largely faced by the country. Thus, in our paper, we have tried to focus on all the aforementioned problems and find a solution to them with the help of our torque sensor-based e-bike. The torque sensor-based e-bike will reduce the strain on the batteries of the bike, as the torque from the user will be providing pedal-assistance. We have also ensured that our bike has an option of charging off-grid via our solar panel charging station, where the batteries of the bike will be charged using the battery swapping method. This method will ensure, that people living in the remote or rural areas do not depend on the national grid; rather on renewable energy sources. This paper describes the data obtained from field test to determine its performance, feasibility and user friendliness. The solar battery charging station is designed and its performance analysis is included as well. The model was developed to save energy, use sufficient solar energy and ensure that it has an option of operating off grid if need be.
