比亞迪dmi的(de)(de)(de)意思(si)是比(bi)(bi)亞(ya)迪的(de)(de)(de)超(chao)級(ji)(ji)(ji)(ji)混動(dong)技術。dmi超(chao)級(ji)(ji)(ji)(ji)混動(dong)基(ji)于大容量電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和(he)大功(gong)(gong)率電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)。車輛(liang)在(zai)行(xing)駛過程中(zhong)由(you)大功(gong)(gong)率電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)驅動(dong)。汽油機(ji)(ji)(ji)的(de)(de)(de)主(zhu)要(yao)功(gong)(gong)能是給電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian),只(zhi)在(zai)需(xu)要(yao)更大功(gong)(gong)率的(de)(de)(de)時候才會直接驅動(dong),只(zhi)有(you)和(he)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)一起工作才能減輕負載。dmi超(chao)級(ji)(ji)(ji)(ji)混動(dong)技術的(de)(de)(de)核心(xin)部(bu)(bu)件是比(bi)(bi)亞(ya)迪最新研發(fa)的(de)(de)(de)曉云插電(dian)(dian)(dian)(dian)(dian)式混合動(dong)力發(fa)動(dong)機(ji)(ji)(ji),其中(zhong)有(you)兩個(ge)重要(yao)部(bu)(bu)件:EHS雙電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、dmi超(chao)級(ji)(ji)(ji)(ji)混動(dong)刀片電(dian)(dian)(dian)(dian)(dian)池(chi)(chi),以及(ji)一系(xi)(xi)列車輛(liang)控(kong)制(zhi)系(xi)(xi)統(tong)、發(fa)動(dong)機(ji)(ji)(ji)控(kong)制(zhi)系(xi)(xi)統(tong)、電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)控(kong)制(zhi)系(xi)(xi)統(tong)和(he)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)管理系(xi)(xi)統(tong),共同(tong)構成超(chao)級(ji)(ji)(ji)(ji)混動(dong)系(xi)(xi)統(tong)。
dmi非常(chang)混(hun)動(dong)(dong)以(yi)大(da)容量(liang)鋰電(dian)(dian)(dian)池(chi)和功率(lv)大(da)的(de)(de)電(dian)(dian)(dian)機(ji)為(wei)基本,車子(zi)在(zai)行車的(de)(de)過(guo)程之中借助功率(lv)大(da)的(de)(de)電(dian)(dian)(dian)機(ji)開(kai)展(zhan)推(tui)動(dong)(dong),而發動(dong)(dong)機(ji)的(de)(de)關鍵作(zuo)用是為(wei)蓄電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian),僅(jin)有在(zai)必須大(da)量(liang)能量(liang)的(de)(de)過(guo)程中才會(hui)直驅,而且也僅(jin)僅(jin)和電(dian)(dian)(dian)機(ji)協調工作(zuo)以(yi)減少負載。dmi非常(chang)混(hun)動(dong)(dong)技術性主要(yao)部(bu)件(jian)為(wei)比亞(ya)迪(di)新制(zhi)造的(de)(de)驍云插混(hun)專(zhuan)用型(xing)汽車發動(dong)(dong)機(ji),也有2個(ge)主要(yao)構件(jian):EHS雙電(dian)(dian)(dian)機(ji)、dmi非常(chang)混(hun)動(dong)(dong)專(zhuan)用型(xing)刀頭充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi),再加上一(yi)系列的(de)(de)白車身控(kong)(kong)制(zhi)系統、汽車發動(dong)(dong)機(ji)控(kong)(kong)制(zhi)系統、電(dian)(dian)(dian)機(ji)控(kong)(kong)制(zhi)系統、充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)智能管(guan)理系統,一(yi)同組(zu)成(cheng)非常(chang)混(hun)動(dong)(dong)系統軟件(jian)。
簡易的說,當(dang)dmi車系用電(dian)量充裕時(shi)(shi),就等同(tong)于(yu)一臺純電(dian)動(dong)(dong)汽車,電(dian)機的驅動(dong)(dong)力供給可以在各種(zhong)各樣(yang)實時(shi)(shi)路(lu)況(kuang)下行車。而(er)當(dang)電(dian)量不足時(shi)(shi),dmi車系就會依據系統(tong)軟件工作(zuo)狀(zhuang)況(kuang),獨立(li)分(fen)辨(bian)用電(dian)量還是(shi)用食油,抑(yi)或是(shi)油電(dian)協作(zuo)。
二、比亞迪dmi有沒有優勢
從目前(qian)的(de)(de)(de)市場環境來(lai)看,無論(lun)是(shi)國內還是(shi)國外擁有(you)比亞(ya)迪這樣(yang)的(de)(de)(de)自(zi)研DM-i技術的(de)(de)(de)確實不多,比亞(ya)迪DM-i技術以其獨特的(de)(de)(de)技術架構和(he)創(chuang)新(xin)的(de)(de)(de)智能控制策略,都能說明比亞(ya)迪mdi是(shi)比較有(you)優勢(shi)的(de)(de)(de)。
首(shou)先是研發(fa)歷(li)史,比亞迪有二十多年的插電(dian)式(shi)混動(dong)技術積(ji)累和(he)(he)自(zi)主(zhu)研發(fa)能力。在插電(dian)式(shi)混動(dong)技術領(ling)域多年的研發(fa)經驗,使(shi)得比亞迪對于技術累積(ji)和(he)(he)發(fa)展方向都(dou)有完整的規劃(hua)和(he)(he)方案,并建立了強大的自(zi)主(zhu)研發(fa)能力,為比亞迪dmi技術的推出奠定了技術基礎。
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)技術(shu)都是(shi)(shi)脫(tuo)胎于原先存(cun)在的(de)技術(shu),關鍵核(he)心點是(shi)(shi)能不能彌補(bu)老舊技術(shu)的(de)BUG。盡(jin)管PHEV有著較高(gao)的(de)節能和環保性(xing)能,但由于其發動機和電動機相(xiang)互配(pei)合(he),存(cun)在一定程度上的(de)炭(tan)罐(guan)飽和問題,這往往會導致PHEV的(de)油(you)耗性(xing)能和排(pai)(pai)放水平受到影響。為(wei)了克服(fu)這一問題,比(bi)亞(ya)迪以dmi串(chuan)并聯架構技術(shu)為(wei)基礎,研發了常壓油(you)箱的(de)油(you)氣排(pai)(pai)放控制(zhi)(zhi)技術(shu)。比(bi)亞(ya)迪的(de)技術(shu)實(shi)現了發動機和車輪(lun)的(de)解耦(ou),多控制(zhi)(zhi)單元(yuan)的(de)協同控制(zhi)(zhi),以及對EV行駛里程、時間與(yu)炭(tan)罐(guan)特(te)性(xing)的(de)相(xiang)關性(xing)深入研究。
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>>
