一、比亞迪的dmi是什么意思
比亞迪dmi的(de)意(yi)思是(shi)比亞(ya)(ya)迪的(de)超(chao)級(ji)(ji)混(hun)動(dong)(dong)技(ji)術。dmi超(chao)級(ji)(ji)混(hun)動(dong)(dong)基(ji)于大容量電(dian)(dian)池和(he)(he)大功(gong)(gong)率電(dian)(dian)機(ji)。車輛在(zai)行駛(shi)過程中由大功(gong)(gong)率電(dian)(dian)機(ji)驅動(dong)(dong)。汽油機(ji)的(de)主(zhu)要(yao)功(gong)(gong)能(neng)是(shi)給電(dian)(dian)池充電(dian)(dian),只在(zai)需要(yao)更大功(gong)(gong)率的(de)時候才(cai)會(hui)直接驅動(dong)(dong),只有和(he)(he)電(dian)(dian)機(ji)一起(qi)工作才(cai)能(neng)減輕負(fu)載。dmi超(chao)級(ji)(ji)混(hun)動(dong)(dong)技(ji)術的(de)核心部件(jian)是(shi)比亞(ya)(ya)迪最新研發的(de)曉(xiao)云插電(dian)(dian)式混(hun)合動(dong)(dong)力發動(dong)(dong)機(ji),其中有兩個(ge)重(zhong)要(yao)部件(jian):EHS雙電(dian)(dian)機(ji)、dmi超(chao)級(ji)(ji)混(hun)動(dong)(dong)刀片電(dian)(dian)池,以及一系列(lie)車輛控制(zhi)系統(tong)(tong)、發動(dong)(dong)機(ji)控制(zhi)系統(tong)(tong)、電(dian)(dian)機(ji)控制(zhi)系統(tong)(tong)和(he)(he)電(dian)(dian)池管理系統(tong)(tong),共同(tong)構成超(chao)級(ji)(ji)混(hun)動(dong)(dong)系統(tong)(tong)。
dmi非(fei)常混動以大(da)(da)容量鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)和功率大(da)(da)的(de)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)為基本,車(che)(che)子在行(xing)車(che)(che)的(de)過(guo)程(cheng)之中借助功率大(da)(da)的(de)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)開展推動,而發動機(ji)(ji)的(de)關(guan)鍵(jian)作用(yong)是為蓄電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian),僅有在必須大(da)(da)量能量的(de)過(guo)程(cheng)中才會直驅,而且也(ye)僅僅和電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)協調工作以減(jian)少負載。dmi非(fei)常混動技術性主(zhu)要部件為比亞迪新制造(zao)的(de)驍云插(cha)混專用(yong)型汽車(che)(che)發動機(ji)(ji),也(ye)有2個(ge)主(zhu)要構件:EHS雙電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)、dmi非(fei)常混動專用(yong)型刀頭充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi),再(zai)加上(shang)一(yi)系(xi)(xi)(xi)列的(de)白車(che)(che)身控(kong)制系(xi)(xi)(xi)統(tong)(tong)(tong)、汽車(che)(che)發動機(ji)(ji)控(kong)制系(xi)(xi)(xi)統(tong)(tong)(tong)、電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)控(kong)制系(xi)(xi)(xi)統(tong)(tong)(tong)、充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)智能管(guan)理系(xi)(xi)(xi)統(tong)(tong)(tong),一(yi)同組(zu)成非(fei)常混動系(xi)(xi)(xi)統(tong)(tong)(tong)軟件。
簡(jian)易(yi)的說,當(dang)(dang)dmi車(che)系用電(dian)量(liang)充(chong)裕時,就等同于(yu)一(yi)臺純電(dian)動(dong)汽(qi)車(che),電(dian)機的驅(qu)動(dong)力供給可(ke)以在各(ge)種各(ge)樣實時路況下行車(che)。而當(dang)(dang)電(dian)量(liang)不足時,dmi車(che)系就會依據系統軟件工作狀況,獨(du)立(li)分辨用電(dian)量(liang)還是(shi)用食油,抑(yi)或是(shi)油電(dian)協作。
二、比亞迪dmi有沒有優勢
從(cong)目前的市(shi)場環境(jing)來看(kan),無論是(shi)國內還是(shi)國外擁有(you)比(bi)亞迪(di)這(zhe)樣的自研DM-i技術(shu)的確實不多,比(bi)亞迪(di)DM-i技術(shu)以(yi)其(qi)獨特的技術(shu)架構和(he)創新的智能(neng)控制策略,都能(neng)說明(ming)比(bi)亞迪(di)mdi是(shi)比(bi)較(jiao)有(you)優勢的。
首先是研(yan)發(fa)歷史,比亞(ya)迪(di)(di)有二十多(duo)年(nian)(nian)的(de)插(cha)電式混動技術(shu)積(ji)累和(he)自主研(yan)發(fa)能(neng)力。在(zai)插(cha)電式混動技術(shu)領域多(duo)年(nian)(nian)的(de)研(yan)發(fa)經驗(yan),使(shi)得比亞(ya)迪(di)(di)對于(yu)技術(shu)累積(ji)和(he)發(fa)展方(fang)向都有完整的(de)規劃(hua)和(he)方(fang)案,并(bing)建立了(le)強大的(de)自主研(yan)發(fa)能(neng)力,為比亞(ya)迪(di)(di)dmi技術(shu)的(de)推出奠定了(le)技術(shu)基(ji)礎(chu)。
其次就是技術轉型,當然有人說比亞迪dmi的技術是脫胎于PHEV技術,這里要說的是新能源的(de)(de)(de)技(ji)(ji)(ji)術都是脫胎于原先(xian)存(cun)(cun)在(zai)的(de)(de)(de)技(ji)(ji)(ji)術,關鍵(jian)核心(xin)點是能(neng)(neng)不能(neng)(neng)彌補老舊技(ji)(ji)(ji)術的(de)(de)(de)BUG。盡(jin)管PHEV有著較(jiao)高(gao)的(de)(de)(de)節能(neng)(neng)和(he)(he)環保性能(neng)(neng),但(dan)由于其發(fa)動機和(he)(he)電動機相互配(pei)合,存(cun)(cun)在(zai)一(yi)定程度上的(de)(de)(de)炭罐飽和(he)(he)問題,這往往會導致PHEV的(de)(de)(de)油耗性能(neng)(neng)和(he)(he)排(pai)放(fang)水平受到影響。為了克服這一(yi)問題,比亞迪以dmi串(chuan)并聯架構(gou)技(ji)(ji)(ji)術為基(ji)礎,研(yan)發(fa)了常壓油箱的(de)(de)(de)油氣排(pai)放(fang)控(kong)制(zhi)技(ji)(ji)(ji)術。比亞迪的(de)(de)(de)技(ji)(ji)(ji)術實(shi)現了發(fa)動機和(he)(he)車輪的(de)(de)(de)解耦(ou),多控(kong)制(zhi)單(dan)元的(de)(de)(de)協同控(kong)制(zhi),以及對(dui)EV行駛里程、時間與炭罐特性的(de)(de)(de)相關性深入研(yan)究。
最后是技術突破,所謂dmi技術簡單來說是以電為主的混動技術,也就是圍繞著大功率電機驅動和大容量動力電池供能為主,發動機為輔的電混架構。其特點在于采用了串并聯技術架構,將發動機與電動機分開控制,以確保發動機不會在純電行駛下頻繁啟動,從而降低了油耗和排放,并且能夠徹底解決PHEV汽油蒸汽自由脫附難題。比亞迪dmi技術通過對發動機、電動機、電池等關鍵零部件的協同控制來實現對PHEV油耗性能和排放水平的優化,進而有效解決常壓油箱汽油蒸汽自由脫附的技術難題,做到了“一靜三得”。比亞迪網點大全>>
