【摘要】：隨著全球環(huán)境的惡化,一次能源的日益缺乏,綠色能源中的電能成為其中的佼佼者,而電動汽車更是其在交通領(lǐng)域應(yīng)用的翹楚。電動汽車的動力來源于電池,受當前動力電池技術(shù)水平的制約,電池的體積問題、環(huán)保問題、使用壽命問題和單次充電時間過長問題成為了限制電動車發(fā)展的主要問題和推廣的瓶頸。電動汽車充電的主要方式有:接觸式和非接觸式兩種,接觸式的充電方式現(xiàn)在已經(jīng)在電動車上應(yīng)用廣泛,但這種方式存在諸多問題,如當接觸式充電使用快速充電模式時,其充電電流非常的大,會直接對局域電網(wǎng)產(chǎn)生影響,并對整個電網(wǎng)的穩(wěn)定性產(chǎn)生隱患,接觸式充電插接操作繁瑣且費時費力十分不方便,當線材老化時會帶來一系列的安全問題。相對于接觸式充電,非接觸式充電電能通過埋在路面下的發(fā)射裝置以無線的方式傳送給接收裝置,從而使電動車少搭載甚至無需搭載儲能電池組、延長續(xù)航里程、提高電能供給的便捷性和安全性。本文首先對磁共振式無線傳能的原理從數(shù)學和電路兩個角度進行了闡述。對比四種常用無線傳能拓撲結(jié)構(gòu),確定了系統(tǒng)選用雙串聯(lián)補償拓撲結(jié)構(gòu)。對系統(tǒng)從數(shù)學和電路角度,建立了控制算法模型,為實際系統(tǒng)設(shè)計提供指導。本文研究了基于磁共振技術(shù)的非接觸式充電系統(tǒng)的控制方法。采用PID控制器實現(xiàn)電動汽車的閉環(huán)充電,提高了傳輸?shù)陌踩煽啃?并對系統(tǒng)為電動汽車進行穩(wěn)定三段式充電的方案進行詳細研究。在實際的方案實施中,本文選用32位處理器作為主控器,通過藍牙2.0模塊進行通訊,根據(jù)接收端發(fā)來的數(shù)據(jù)對充.電的發(fā)射端進行實時的調(diào)節(jié),從而實現(xiàn)軟件的閉環(huán)設(shè)計,通過硬件鎖相環(huán)技術(shù)完成對頻率的跟蹤,實現(xiàn)發(fā)射端的閉環(huán)調(diào)節(jié),最終完成軟硬件設(shè)計。
[Abstract]:With the deterioration of the global environment and the increasingly lack of primary energy, the electric energy in green energy has become one of the best among them, and the electric vehicle is the leading application in the field of transportation. The electric vehicle's power comes from the battery, restricted by the current power battery technology level, the battery volume question, the environmental protection question, The problem of service life and the long time of single charge become the main problem and bottleneck in the development of electric vehicle. There are two main ways of electric vehicle charging: contact charging and non-contact charging. Contact charging has been widely used in electric vehicles, but there are many problems in this way, such as when contact charging uses rapid charging mode. The charging current is very large, which will directly affect the local power network and the stability of the whole power network. The contact charging and plugging operation is cumbersome and time-consuming and very inconvenient. A series of safety problems arise when the wire is aging. Rather than contact-charging, contactless charging electricity is wirelessly transmitted to the receiver via a buried emitter, allowing an electric vehicle to carry fewer or no energy storage batteries and extend its range. Improve the convenience and safety of power supply. In this paper, the principle of magnetic resonance wireless energy transmission is described from the aspects of mathematics and circuit. By comparing four kinds of wireless energy transmission topologies, the double series compensation topology is selected. The control algorithm model of the system is established from the point of view of mathematics and circuit, which provides guidance for the practical system design. The control method of non-contact charging system based on magnetic resonance technology is studied in this paper. The closed-loop charging of electric vehicle is realized by using PID controller, which improves the safety and reliability of transmission. The scheme of stable three-stage charging for electric vehicle is studied in detail. In the actual implementation of the scheme, the 32-bit processor is chosen as the main controller, which communicates through Bluetooth 2.0 module and is charged according to the data sent from the receiver. The electric transmitter adjusts in real time so as to realize the closed-loop design of the software. The frequency is tracked by the hardware phase-locked loop technology and the closed-loop regulation of the transmitter is realized. Finally the software and hardware are designed.
