【摘要】：電動(dòng)汽車行業(yè)隨著國(guó)家的推動(dòng),這個(gè)新興的行業(yè)已經(jīng)進(jìn)入了蓬勃發(fā)展的春天,也帶動(dòng)了相關(guān)配套產(chǎn)業(yè)的發(fā)展,其中在電池、充電樁等技術(shù)上已經(jīng)有了很大的進(jìn)展和突破,迫切需要充電接口技術(shù)能適應(yīng)電動(dòng)汽車行業(yè)發(fā)展的速度和方向。一直以來(lái)國(guó)內(nèi)電動(dòng)汽車充電接口一直以來(lái)發(fā)展緩慢,市場(chǎng)上充電接口種類繁多、接口不統(tǒng)一、質(zhì)量不穩(wěn)定,非常不利于推動(dòng)整個(gè)電動(dòng)汽車行業(yè)的發(fā)展。國(guó)際上歐洲各國(guó)和日本在電動(dòng)汽車充電接口的發(fā)展比我們國(guó)內(nèi)要早,但是近年來(lái)也沒(méi)有在技術(shù)上進(jìn)行突破。其中歐洲執(zhí)行國(guó)際電工委員會(huì)(IEC)標(biāo)準(zhǔn),美國(guó)執(zhí)行美國(guó)汽車工程師協(xié)會(huì)(SAE)標(biāo)準(zhǔn),日本執(zhí)行日本電動(dòng)汽車協(xié)會(huì)(JEVS)標(biāo)準(zhǔn);國(guó)內(nèi)接口執(zhí)行2011年發(fā)布實(shí)施的GB/T20234-2011《電動(dòng)汽車傳導(dǎo)充電用連接裝置》標(biāo)準(zhǔn)。GB/T20234標(biāo)準(zhǔn)是根據(jù)國(guó)內(nèi)具體情況依據(jù)、及的相關(guān)標(biāo)準(zhǔn)制定的,能達(dá)到和國(guó)際和國(guó)內(nèi)的充電接口有統(tǒng)一的互換標(biāo)準(zhǔn)。為了滿足市場(chǎng)的需求和適應(yīng)發(fā)展的需要,開展電動(dòng)汽車充電接口的關(guān)鍵技術(shù)研究和突破勢(shì)在必行。目前國(guó)際及國(guó)內(nèi)的標(biāo)準(zhǔn)體系中均規(guī)定充電接口的機(jī)械壽命為空載10000次,接觸電阻0.5mΩ、溫升不超過(guò)50K。根據(jù)充電接口的使用頻率測(cè)算預(yù)計(jì)使用壽命在5年以下,但是汽車的使用時(shí)間卻是這個(gè)的兩倍甚至以上。為了提高汽車的安全性能和核心部件的使用期限,本課題以電動(dòng)汽車傳導(dǎo)式充電接口為研究對(duì)象,對(duì)充電接口的關(guān)鍵技術(shù)進(jìn)行研究,將充電接口的機(jī)械壽命提高到20000次,使用壽命提高到10年左右,達(dá)到汽車的使用壽命并減少了報(bào)廢接口造成的環(huán)境污染及資源浪費(fèi);將接觸電阻降到0.3mΩ以內(nèi)、溫升下降到30K左右,可以使充電接口更安全并適應(yīng)更高環(huán)境溫度使用的需要。充電接口的接觸電阻、溫升、機(jī)械壽命這幾項(xiàng)關(guān)鍵技術(shù)主要體現(xiàn)在接觸對(duì)上。本課題針對(duì)接觸對(duì)進(jìn)行系統(tǒng)的、深入的研究和分析,包括接觸件的結(jié)構(gòu)分析、電及熱應(yīng)力傳導(dǎo)分析、材料分析、表面工程技術(shù)、摩擦及磨損、主要失效模式分析、可靠性分析等工作,研究的同時(shí)提出獨(dú)創(chuàng)的的雙曲面籠式插孔,該插孔結(jié)合了常用接觸件的優(yōu)點(diǎn),并進(jìn)行了結(jié)構(gòu)創(chuàng)新。從雙曲面籠式插孔結(jié)構(gòu)、接觸電阻、插拔力、溫升、機(jī)械壽命等方面進(jìn)行了深入研究和仿真計(jì)算,然后投入試制生產(chǎn),最后將樣件進(jìn)行一系列的試驗(yàn)測(cè)試,與理論值及要求值進(jìn)行對(duì)比分析。從理論和實(shí)踐都證明本次研究達(dá)到了預(yù)期的目標(biāo)。通過(guò)本次研究,將雙曲面籠式插孔應(yīng)用在充電接口上,在標(biāo)準(zhǔn)化的基礎(chǔ)上,提高了充電接口的安全性能,將機(jī)械壽命提高了兩倍,適應(yīng)了充電接口的發(fā)展方向,推動(dòng)了國(guó)內(nèi)充電接口的發(fā)展,使此類充電接口達(dá)到行業(yè)領(lǐng)先水平。
[Abstract]:With the promotion of the country, this emerging industry has entered the spring of vigorous development, and has also led to the development of related supporting industries. Among them, there has been great progress and breakthrough in technology such as batteries, charging piles, etc.There is an urgent need for charging interface technology to adapt to the speed and direction of the development of the electric vehicle industry.The domestic electric vehicle charging interface has been developing slowly all the time. There are many kinds of charging interfaces in the market, the interface is not uniform and the quality is unstable, which is very unfavorable to the development of the whole electric vehicle industry.The development of electric vehicle charging interface in Europe and Japan is earlier than that in our country, but in recent years there has been no technical breakthrough.Among them, Europe implements the IEC standard, the United States implements the American Association of Automotive Engineers (SAE) standard, and Japan implements the JEVS standard of Japan Electric vehicle Association.The domestic interface implements the GB/T20234-2011 standard. GB / T20234, issued in 2011, is based on the specific situation in China and related standards.Can meet the international and domestic charging interface has a unified exchange standard.In order to meet the needs of market and development, it is imperative to research and break through the key technology of electric vehicle charging interface.At present, it is stipulated in international and domestic standard systems that the mechanical life of charging interface is 10000 times without load, contact resistance is 0.5 m 惟, temperature rise is not more than 50 K.The estimated service life is less than five years based on the frequency of the charging interface, but the car is twice as long as this one.In order to improve the safety performance of the vehicle and the service life of the core components, this paper takes the conductive charging interface of the electric vehicle as the research object, studies the key technology of the charging interface, and increases the mechanical life of the charging interface to 20000 times.When the service life is increased to about 10 years, the service life of the automobile is reached and the environmental pollution and resource waste caused by the scrap interface are reduced, the contact resistance is reduced to less than 0.3 m 惟, and the temperature rise is reduced to about 30 K.It can make the charging interface safer and adapt to the need of higher ambient temperature.The contact resistance, temperature rise and mechanical life of the charging interface are mainly reflected in the contact pair.This subject is a systematic and in-depth study and analysis of contact pairs, including contact structure analysis, electrical and thermal stress conduction analysis, material analysis, surface engineering technology, friction and wear, main failure mode analysis,At the same time, the original hyperboloid cage Jack is put forward, which combines the advantages of common contacts, and the structure is innovated.The hyperboloid cage hole structure, contact resistance, insertion force, temperature rise, mechanical life and so on are studied and simulated, then put into trial production, and a series of tests are carried out.Compared with the theoretical value and the required value.Both theory and practice have proved that this study has achieved the expected goal.Through this study, the hyperboloid cage Jack is applied to the charging interface. On the basis of standardization, the safety performance of the charging interface is improved, the mechanical life is increased twice, and the development direction of the charging interface is adapted.Promote the development of domestic charging interface, so that this kind of charging interface to the industry leading level.
