摘要：環(huán)境惡化和能源緊張使得當(dāng)今汽車行業(yè)面臨著前所未有的考驗(yàn)，隨著環(huán)保和節(jié)能意識(shí)的逐漸深入人心，人們對(duì)汽車這一交通工具也提出了環(huán)保和節(jié)能的要求，為解決這些問題，電動(dòng)汽車正呈獻(xiàn)出加速發(fā)展的趨勢。傳統(tǒng)有線充電有很多弊端，難以滿足電動(dòng)汽車市場以及顧客的需求。無線充電技術(shù)恰好又能使電動(dòng)汽車擺脫傳統(tǒng)有線充電困難的束縛，簡化了充電設(shè)備，實(shí)現(xiàn)遠(yuǎn)距離的電能傳輸，使得電動(dòng)汽車有持久的續(xù)航能力。在現(xiàn)有資源匱乏的環(huán)境下，無線充電技術(shù)的發(fā)展將會(huì)推動(dòng)電動(dòng)汽車行業(yè)的快速發(fā)展。
文中首先介紹了無線充電技術(shù)在國內(nèi)外的發(fā)展歷史、現(xiàn)狀及趨勢，然后闡述了無線充電技術(shù)的基本原理，并對(duì)現(xiàn)存在的三種主要無線充電技術(shù)作了介紹和比較。
最后在考慮無線充電技術(shù)可行性的基礎(chǔ)上，應(yīng)用共振耦合技術(shù)原理對(duì)系統(tǒng)電路進(jìn)行了設(shè)計(jì)，并運(yùn)用MATLAB進(jìn)行電路設(shè)計(jì)和仿真,分析了耦合頻率、負(fù)載對(duì)傳輸功率以及傳輸效率的影響。文章結(jié)尾處對(duì)該技術(shù)在實(shí)際運(yùn)用上進(jìn)行合理的假設(shè)，并對(duì)不同功能的電動(dòng)汽車提出了相應(yīng)的解決方案。

Design and Analysis of Electronic Vehicle Wireless Charging System
AbstractNowadays, the automotive industry is faced with unprecedented challenges for environmental deterioration and energy shortageEnergy saving and environmental protection is becoming so important in our daily life. Then, electric vehicle is presenting a trend of accelerated development. Traditional cable charging has many disadvantages; it’s difficult to meet the demand of electric car market.Wireless charging technology exactly can get rid of the bondage of traditional cable charging,simplifies the charging equipment. Electric vehicles will have a much longer mile range by using wireless charging. Under the environment of shortage resources, the development of wireless charging technology will promote the rapid development of the electric car industry.
This paper first introduces the history of wireless charging system’s development, including present situation and future trend .Then,present the basic principle of wireless charging technology, and the existing three main wireless charging technologies are introduced and compared.
On the basis of the feasibility of wireless charging technology, a charging system is designedby using the principle of resonance coupling technique and simulated in the MATLAB. Also, the relationship between coupling frequency and load power,transmission efficiency is designed .Finally, a reasonable assumption has made to the practical application of this technique, and corresponding solutions to the different functions of electric cars are put forward.
