Research On Solar Charging Device Of Electric Bicycles

China has gradually become the most populous country of electric bicycle quantities. Chinese reality determines our traffic tools may not like Euramerican developed country that comprehensively use cars, and electric bicycle is likely to become the main personal transport. Electric bicycles are developed in the resent ten years. It is based on the progress of the electric car technology and modern hi-tech achievements. According to the citizens' demand survey of the country's major cities, as much as 76 percent of the citizens will have electric bicycle as traffic tool. As to a lot of people, electric bikes become their travel choice, but because electric batteries are very heavy, getting indoor charging are very laborious, and also, electric bicycles often have no electricity in halfway. So solar electric bicycle(charging device) research and development become a recent hot topic.Energy issue is a worldwide basis. The transition period to new energy is to come sooner or later. Solar energy as the one kind of energy, compared with fossil fuels such as the coal, oil, natural gas, nuclear power and so on, has the advantages of universal, harmless, huge, lasting, etc. Therefore the development of solar electric bikes is promising. In the new period advocating environmental protection and low carbon, this is also an inevitable trend that electric bicycle industry develops.This article mainly talks about the electric bicycle solar charging device. Based on photovoltaic energy technology and independent photovoltaic power system designing, it developed solar charging system device on the basis of the applicable to electric bicycle and adopted the most high-power tracking method to analyze the efficiency of system and performance. It makes a detailed knowledge to the concept and components of a small independent photovoltaic power generation system, the development status of domestic and overseas' research, the current research problems and the key technology and development trends and application prospect. The essay is mainly through the average daily power that electric bicycles consume to determine the power needed for solar panels, and then determine the size of panels. Considering the electric bicycle's appearance and safety, and many other factors, the article finally adopts ceiling installation method to fix solar panels; and according to the exterior environment such as light, temperature and so on having different influences on the different components of the system, do an in-depth analysis on the overall system performance parameters. This design of solar charging devices can realize the solar charging of electric bicycle. It can resolve the charging hard problem that the ordinary electric bicycle have, and also use the new energy solar energy which is low carbon and environmental protection.
