This project proposes a regenerative braking system for electric bicycle based on DSP. The proposed method is used to adjust the switching sequence of the inverter, so that the braking energy can be used to charge the battery. With the cooperation of braking energy recovery technology and a digital signal processor as the control unit, the braking energy is transformed to electrical energy for battery charging.
Introduction
I. INTRODUTION
According to the traffic administrative department of the results show that the number of electric bicycles is growing up, at the same time, traffic accident occurred in electric bicycle becoming more and more. The electric bicycle’s growth brings new difficulty to urban traffic management. [1].
16 out of 30 top polluted cities in the world are in India. The air in these cities contains high levels of dangerous particulate matter, small enough to enter the human bloodstream through the lungs a problem that contributes to an estimated 7 million premature deaths each year. Irrespective of various efforts of alternative fuel and technology, emissions are not observed to be in control [2].
This Bicycle is designed and made in very less cost as compared to original cost, so any one can afford this Bicycle. As we know that due fuel powered vehicles, the emission of toxic gases is increasing day by day, due to this 4.3 million people [3].
The Regenerative method of adding a converter not only increases cost but also reduces conversion efficiency. This project proposes a DSP (digital signal processor) controlled bicycle with regenerative braking. When the system controller receives the braking signal, the motor can work as a generator, and the energy generated from braking can charge the battery. This project proposes a DSP controlled electric bicycles with regenerative braking control. The kinetic energy is converted into electric energy and stored in batteries when braking, thus improve the driving range and performance of electric bicycles. [4].
Conclusion
According to the analysis results of electric bicycle hidden safety dangers in traffic, we put forward some measures to improve the urban management of electric bicycle traffic safety performance, reduce electric bicycle to urban traffic for constructing city of interference, in order to contribute harmonious traffic. This project is designed to improve the normal bicycle and make it extra efficient. The electric bicycle is hybrid and so it can run by electrical energy, solar energy, and dynamo and can also be pedaled there by still retaining the exercise people drive from riding bicycle.
