摘 要
在这个快速发展的时代，我们对能源的需求越来越多，对地球家园的污染也越来越大。就交通而言，各类汽车不断增加，对空气的污染也逐渐严重。为了更好的保护我们的家园，也为了便利人们的出行，电动车成为广大人民众的首选，它方便，快捷，价格便宜，符合普通大众的出行。但是电动车的普及，虽然为人民大众的生活提供了很大的方便，但是电的供应需要大量的煤炭等一些不可再生能源，煤炭的大量燃烧不仅使这些不可再生资源的枯竭，还造成了很大的污染。人们赖以生存的空气，水资源都被严重的污染，因此我们需要清洁无污染的太阳能来发电。
这次的设计是以太阳能光伏发电为前提，把太阳光转化为电能提供给电动车来利用。首先研究的是小型独立光伏发电系统，它发展的程度以及如今发展的趋势，而太阳能转化的效率和光伏器件的成本也是一个很大的问题。光伏器件的价格是有多方面的因素来决定的，而太阳能的转化效率是可以深入研究的。为了使太阳能的转化效率达到最高，本文采用了最大功率点跟踪分析法来研究确定它的转化效率，以及太阳能电池板的确定。本文总体分为对太阳能电池板的研
究，充电系统的设计，最大功率跟踪法（MPPT）的介绍，其中充电系统的设计包括DC升压电路和充电控制电路。

Abstract太阳能汽车
In this era of rapid development, we are more and more demand fore nergy, pollution of the earth is becoming more and morebig. Growing in terms of traffic, all kinds of cars, air pollution is increasingly serious. In order to better protect our home, and to facilitate the travel of people, electric cars become the first choice for the people, it is convenient, fast, cheap, conforms to the general public. But the popularity of electric cars, although the lives
of the people provides a great convenience, but the supply of electricity needs a lot of coal and other non-renewable energy, the burning of coal not only make the depletion of non-renewable resources, also caused a lot of pollution. People live in the air and water are serious pollution, so we need to clean pollution-free solar energy to generate electricity.
This design is to use solar energy to electric power, mainly on the basis of independent photovoltaic design a electric bicycle charging system, first of all, is the study of the small independent photovoltaic powergeneration system, its development degree and the development trend of nowadays, and the cost of solar energy conversion efficiency and photovoltaic devices is also a big problem. The price of photovoltaic devices have many factors to determine, and the conversion efficiency of solar energy can be in-depth study. In order to make the conversion efficiency of solar energy to achieve the highest, in this paper, using the method of maximum power point tracking to determine its efficiency. Also the size of the solar panels is calculated through the experiment. This paper is divided into the study of solar panels, the overall design of the charging system, the method of maximum power tracking (MPPT) is introduced, including the design of the charging syste
m including a DC charging booster circuit and control circuit.
