Abstract
    This paper design first introduced the history of the development of electric bicycles very basic knowledge of electric vehicles, including the role of classification principle, and so on, followed by in-depth into the electric car introduced an important part of - chargers, the most important thing is introduced The three steps charger works extremely important parameters for us to understand their characteristics, more in-depth study. Papers also specifically addressed the shortcomings of the Three-stage battery charger and pay in the solution. Another thesis is an integral part of the charger detection, talked about the principles of the charger detection methods, such as the contents, but also a number of cases of failure to request an extremely important case, not mentioned detected some cutting tools and testing components of the identification And so on, the papers are summarized. Behind a list of some of the charger circuit element to our deeper understanding of the charger is very helpful, finally made a more charger use, purchase and maintenance, and also introduced the battery charger is closely related to the Use and maintenance, the development of electric bicycles is unstoppable, more and more energy in the future tense circumstances, the power of this green energy will replace those on Earth less and less energy, electric cars popular in the affirmative, chargers The development is inevitable.
