【摘要】：傳統(tǒng)的燃油汽車雖然給人們的日常生活和交通帶來了巨大的便利,但同時(shí)也消耗著大量的燃油,并且排放出大量的尾氣,使得能源危機(jī)和空氣污染進(jìn)一步加重,影響了人們的健康生存。在能源和環(huán)境問題的雙重壓力下,要保持汽車行業(yè)的可持續(xù)發(fā)展,研究環(huán)保和清潔的電動(dòng)汽車勢在必行。但是電動(dòng)汽車的快速充電問題卻成為其發(fā)展的主要瓶頸,本文的主要內(nèi)容是研究電動(dòng)汽車智能充電系統(tǒng)。本文以蘇州市應(yīng)用基礎(chǔ)研究計(jì)劃項(xiàng)目(工業(yè)部分)為依托,運(yùn)用現(xiàn)代高頻開關(guān)電源技術(shù)、PWM脈沖控制技術(shù)和ARM處理器,對(duì)電動(dòng)汽車智能充電系統(tǒng)展開了研究和設(shè)計(jì)。論文研究的主要內(nèi)容如下:(1)論文首先討論了當(dāng)前國內(nèi)外對(duì)電動(dòng)汽車充電系統(tǒng)的研究狀況,并闡述了常用的電動(dòng)汽車蓄電池的性能、充放電特性、充電方法以及控制技術(shù)。通過對(duì)傳統(tǒng)充電方法和常規(guī)快速充電方法的對(duì)比分析,提出了分階段正負(fù)脈沖充電,其負(fù)脈沖可以有效地消除蓄電池在充電過程中產(chǎn)生的極化現(xiàn)象。采用高頻開關(guān)IGBT設(shè)計(jì)了主充電電路,詳細(xì)的分析了整流、濾波電路、脈沖寬度調(diào)制電路的設(shè)計(jì)方法與工作原理。(2)論文設(shè)計(jì)了蓄電池監(jiān)測電路,實(shí)時(shí)的監(jiān)測蓄電池的端電壓、充電電流和內(nèi)部溫度。根據(jù)蓄電池的實(shí)際充電狀態(tài)來選擇相應(yīng)的充電參數(shù)能夠有效的避免蓄電池發(fā)生過度充電。(3)采用Lab VIEW設(shè)計(jì)了上位機(jī)管理系統(tǒng)。對(duì)整個(gè)充電系統(tǒng)的狀態(tài)進(jìn)行監(jiān)控,并將系統(tǒng)的充電數(shù)據(jù)保存至數(shù)據(jù)庫。論文最后對(duì)系統(tǒng)主充電電路進(jìn)行了仿真,并通過模擬充電參數(shù)完成了上位機(jī)管理系統(tǒng)的調(diào)試。根據(jù)仿真和調(diào)試結(jié)果,較好的達(dá)到了預(yù)定的設(shè)計(jì)要求。本文研究的電動(dòng)汽車智能充電系統(tǒng)對(duì)電動(dòng)汽車的發(fā)展具有一定的推動(dòng)作用。
[Abstract]:Although the traditional fuel vehicles have brought great convenience to people's daily life and traffic, they also consume a lot of fuel and discharge a lot of exhaust gas, which makes the energy crisis and air pollution further aggravated, affecting the people's healthy survival. Under the dual pressure of energy and environment, it is necessary to maintain the automobile industry. It is imperative for the sustainable development of the electric vehicle to study the environmental protection and clean electric vehicles. However, the fast charging problem of the electric vehicle is the main bottleneck of its development. The main content of this paper is to study the intelligent charging system of the electric vehicle. This paper, based on the Suzhou application basic research project (industrial part), uses the modern high frequency switch. Power technology, PWM pulse control technology and ARM processor have been studied and designed for the intelligent charging system of electric vehicles. The main contents of this paper are as follows: (1) first, the research status of electric vehicle charging system at home and abroad is discussed, and the performance, charging and discharging characteristics and charging of the commonly used electric vehicle batteries are expounded. Method and control technology. Through comparison and analysis of traditional charging method and conventional fast charging method, a phased positive and negative pulse charge is proposed. The negative pulse can effectively eliminate the polarization of the battery during the charging process. The main charge circuit is designed by high frequency switch IGBT, and the rectifier and filter circuit are analyzed in detail. The design method and working principle of pulse width modulation circuit. (2) a battery monitoring circuit is designed in this paper to monitor the terminal voltage, charge current and internal temperature of the battery in real time. According to the actual charging state of the battery, the corresponding charging parameters can be effectively avoided. (3) the design of the battery is designed by Lab. The state of the whole charging system is monitored and the charge data of the system is saved to the database. Finally, the main charging circuit of the system is simulated, and the host computer management system is debugged through the simulation of the charging parameters. According to the simulation and the test results, the intended design is achieved. The intelligent charging system of electric vehicles in this paper has a certain role in promoting the development of electric vehicles.
