【摘要】：化石燃料汽车在给人们带来生产与生活上便利的同时,也造成了石油资源紧张与环境破坏日益严重等问题。电动汽车因以可再生电能作为动力来源且无任何尾气排放,能够解决化石燃料汽车的上述问题。然而,电动汽车电源管理系统的发展现状却严重制约了电动汽车的推广与普及。要从根本上解决这一电动汽车电源管理问题,需要在电池基础材料、基础设施建设等各领域的突破进展。在现有技术条件下,如何提高电动汽车用蓄电池的充电效率、缩短电池充电时间、保证电池充电及使用中的安全、延长电池使用寿命、简化电池充电过程,是我们急需解决的。 本文详细论述了一台便携式电动汽车智能充电机的研究与开发过程,本文首先从充电机研发这一课题的背景入手,阐述现实的矛盾,对比国内外研究现状,指出充电机研发的必要性,列出充电机设计指标、总体设计思路以及本文所要研究的内容。然后,对电动汽车广泛使用的铅酸蓄电池的充放电原理与特性进行了说明,介绍了比较流行的充电方法,并给出了本文所设计的电池充电方法。接下来,利用大量的篇幅,详细论述了充电机的功率电路与控制电路,其中包括交错并联CRM Boost PFC模块的设计与分析、软开关技术介绍、全桥串联谐振的原理分析、着重分析了全桥串联谐振工作在DCM的情况、高频变压器的设计、电池充放电回路的设计与分析、IGBT驱动电路的设计以及充电机监测与控制电路的设计。最后,论述了充电机各个模块及整机的调试过程与结果。证明了,本文所设计的充电机能够完全满足当初所提出的设计指标,且能出色的完成电动汽车蓄电池的充电任务。
[Abstract]:Fossil fuel vehicles not only bring convenience to people's production and life, but also cause oil resource shortage and environmental damage. Electric vehicles (EV) can solve the problem of fossil fuel vehicles by using renewable energy as power source and without any exhaust emissions. However, the development of electric vehicle power management system seriously restricts the popularization and popularization of electric vehicle. In order to solve the problem of electric vehicle power management fundamentally, it is necessary to make breakthrough progress in battery basic materials, infrastructure construction and other fields. Under the existing technical conditions, how to improve the charging efficiency of battery for electric vehicle, shorten the charging time of battery, ensure the safety of battery charge and use, prolong the life of battery and simplify the process of battery charging, is an urgent problem for us to solve. In this paper, the research and development process of a portable electric vehicle intelligent charger is discussed in detail. Firstly, this paper starts with the background of the research and development of the charger, expounds the realistic contradiction, and compares the domestic and foreign research status. This paper points out the necessity of the research and development of the charger, lists the design index of the charger, the overall design idea and the contents of this paper. Then, the charging and discharging principles and characteristics of lead-acid batteries widely used in electric vehicles are explained, the more popular charging methods are introduced, and the battery charging methods designed in this paper are given. Then, with a great deal of space, the power circuit and control circuit of the charger are discussed in detail, including the design and analysis of the interleaving parallel CRM Boost PFC module, the introduction of soft switching technology, the principle analysis of full-bridge series resonance. The design of DCM, the design of high frequency transformer, the design and analysis of battery charging and discharging circuit, the design of IGBT drive circuit and the design of monitor and control circuit of charger are analyzed emphatically. Finally, the debugging process and results of each module and the whole machine are discussed. It is proved that the chargers designed in this paper can completely meet the original design specifications and can finish the charging task of electric vehicle batteries.
