The intention of this project is to build a Flywheel base rechargeable battery, for energy saving as well as longer range for electric vehicle; currently model is design & build for bicycle and by making some changes we can use this model in two wheelers as well as in cars. This project will help to develop engineering skills while learning about regenerating electricity or using more efficiently and satisfying our requirement of more range for EVs. We are going to use the dynamo & Flywheel to generate electricity due to which our battery will be recharge. This is totally clean way of regenerating energy. As fuel is not a renewable energy sources are limited and the prices are increasing day by day also, extraction on conventional fuels are harmful for nature. It will not be affordable by a common man after some period & use of fossil fuels increase global warming. So we need to use electricity as efficiently as we can, so everybody can afford and use more and more electric transportation. Also it eliminates the emission of CO₂ which will reduce the pollution.

For the project to work we need use dynamo & flywheel with bearing for lesser friction as we know due to friction energy losses will be their; also in some cases we can use strong electromagnets to regenerate electricity but as we want to use this application for e-bicycle where we will get less torque & power for flywheel. The basic idea of this principle comes from the functioning of motor, that is how it rotates in the magnetic field and cut’s the magnetic line and how flux is introduced into the coil. The motivation behind the project is to generate electricity for longer range for all types EV bikes so we are turning towards dynamo & flywheel application. As when the bike is at lower speed still the motor will rotate with it specified RPM and that energy will be transferred to flywheel & by using flywheel inertia we can recharge battery. Also, while breaking also similar phenomena happen & in that case too we can recharge the battery to increase the range of all types of EVs.
