【摘要】：化石燃料汽車在給人們帶來生產(chǎn)與生活上便利的同時(shí),也造成了石油資源緊張與環(huán)境破壞日益嚴(yán)重等問題。電動(dòng)汽車因以可再生電能作為動(dòng)力來源且無任何尾氣排放,能夠解決化石燃料汽車的上述問題。然而,電動(dòng)汽車電源管理系統(tǒng)的發(fā)展現(xiàn)狀卻嚴(yán)重制約了電動(dòng)汽車的推廣與普及。要從根本上解決這一電動(dòng)汽車電源管理問題,需要在電池基礎(chǔ)材料、基礎(chǔ)設(shè)施建設(shè)等各領(lǐng)域的突破進(jìn)展。在現(xiàn)有技術(shù)條件下,如何提高電動(dòng)汽車用蓄電池的充電效率、縮短電池充電時(shí)間、保證電池充電及使用中的安全、延長電池使用壽命、簡化電池充電過程,是我們急需解決的。 本文詳細(xì)論述了一臺(tái)便攜式電動(dòng)汽車智能充電機(jī)的研究與開發(fā)過程,本文首先從充電機(jī)研發(fā)這一課題的背景入手,闡述現(xiàn)實(shí)的矛盾,對比國內(nèi)外研究現(xiàn)狀,指出充電機(jī)研發(fā)的必要性,列出充電機(jī)設(shè)計(jì)指標(biāo)、總體設(shè)計(jì)思路以及本文所要研究的內(nèi)容。然后,對電動(dòng)汽車廣泛使用的鉛酸蓄電池的充放電原理與特性進(jìn)行了說明,介紹了比較流行的充電方法,并給出了本文所設(shè)計(jì)的電池充電方法。接下來,利用大量的篇幅,詳細(xì)論述了充電機(jī)的功率電路與控制電路,其中包括交錯(cuò)并聯(lián)CRM Boost PFC模塊的設(shè)計(jì)與分析、軟開關(guān)技術(shù)介紹、全橋串聯(lián)諧振的原理分析、著重分析了全橋串聯(lián)諧振工作在DCM的情況、高頻變壓器的設(shè)計(jì)、電池充放電回路的設(shè)計(jì)與分析、IGBT驅(qū)動(dòng)電路的設(shè)計(jì)以及充電機(jī)監(jiān)測與控制電路的設(shè)計(jì)。最后,論述了充電機(jī)各個(gè)模塊及整機(jī)的調(diào)試過程與結(jié)果。證明了,本文所設(shè)計(jì)的充電機(jī)能夠完全滿足當(dāng)初所提出的設(shè)計(jì)指標(biāo),且能出色的完成電動(dòng)汽車蓄電池的充電任務(wù)。
[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.
