一、混合動力轎車可以純電行駛嗎

混合動力汽車可(ke)以(yi)(yi)只(zhi)用電(dian)，混合動力汽車可(ke)以(yi)(yi)分(fen)為三(san)個種類，分(fen)別是插電(dian)式(shi)混合動力、油電(dian)混合動力以(yi)(yi)及增程(cheng)式(shi)混動，以(yi)(yi)下是詳細的介紹(shao)：

插電式混合動力汽車：插(cha)電(dian)式混(hun)合動力汽車的電(dian)池(chi)相對比較(jiao)大，可以外(wai)部(bu)充電(dian)，可以用(yong)純(chun)電(dian)模(mo)式行(xing)駛(shi)，電(dian)池(chi)電(dian)量耗盡(jin)后再以混(hun)合動力模(mo)式（以內燃機為主）行(xing)駛(shi)，并適時(shi)向電(dian)池(chi)充電(dian)。

油電混合動力汽車：由于油電混合動(dong)(dong)力汽車(che)的(de)電池(chi)容量較小，只需要在起(qi)步或停車(che)，加速(su)或減速(su)時供(gong)應回收回收能(neng)量，所以不(bu)能(neng)純(chun)電模式(shi)下較長距離行駛。這是比(bi)較成(cheng)熟的(de)一種類(lei)型(xing)混合動(dong)(dong)力汽車(che)。

增程式混合動力汽車：增程式(shi)(shi)(shi)混(hun)合動(dong)(dong)(dong)(dong)力的(de)原理是用發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)進(jin)行發電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)進(jin)行驅動(dong)(dong)(dong)(dong)的(de)車輛。當電(dian)(dian)(dian)(dian)池組電(dian)(dian)(dian)(dian)量(liang)充足時采(cai)用純(chun)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)模式(shi)(shi)(shi)行駛(shi)，而當電(dian)(dian)(dian)(dian)量(liang)不(bu)足時，車內(nei)發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)啟動(dong)(dong)(dong)(dong)，帶動(dong)(dong)(dong)(dong)發電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)為動(dong)(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)，提供電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)運行的(de)電(dian)(dian)(dian)(dian)力（即增程模式(shi)(shi)(shi)）。區別于插電(dian)(dian)(dian)(dian)式(shi)(shi)(shi)和油電(dian)(dian)(dian)(dian)混(hun)合動(dong)(dong)(dong)(dong)力，增程式(shi)(shi)(shi)混(hun)合動(dong)(dong)(dong)(dong)力無論什么情況下(xia)，都不(bu)能由發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)直(zhi)接驅動(dong)(dong)(dong)(dong)車輪行駛(shi)，僅能通過(guo)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)驅動(dong)(dong)(dong)(dong)。但(dan)它也能夠像插電(dian)(dian)(dian)(dian)式(shi)(shi)(shi)混(hun)合動(dong)(dong)(dong)(dong)力汽車—樣，通過(guo)外接電(dian)(dian)(dian)(dian)源進(jin)行充電(dian)(dian)(dian)(dian)。

二、動力混合汽車能跑長途嗎

動力混合汽車是(shi)可(ke)以(yi)長途行駛的。混合動(dong)力(li)車(che)搭載(zai)了(le)電(dian)機(ji)和(he)(he)動(dong)力(li)電(dian)池，電(dian)機(ji)和(he)(he)電(dian)池的電(dian)能(neng)完全由發(fa)動(dong)機(ji)提供(gong)，可(ke)作為燃油(you)車(che)使用。所以(yi)油(you)電(dian)混合動(dong)力(li)汽車(che)跑長途是(shi)沒有(you)問題的。

另外，油(you)電(dian)混合動(dong)(dong)力高(gao)速行駛(shi)用(yong)的是(shi)電(dian)還是(shi)油(you)，最(zui)好使(shi)用(yong)油(you)，因為(wei)(wei)混合動(dong)(dong)力汽(qi)車(che)只有(you)(you)在起步或(huo)低速行駛(shi)時才使(shi)用(yong)電(dian)機(ji)驅動(dong)(dong)。汽(qi)車(che)在高(gao)速行駛(shi)時，以發(fa)動(dong)(dong)機(ji)驅動(dong)(dong)為(wei)(wei)主，電(dian)動(dong)(dong)機(ji)為(wei)(wei)輔。油(you)電(dian)混動(dong)(dong)車(che)型的動(dong)(dong)力系統會根據不同(tong)情(qing)況自由(you)切換發(fa)動(dong)(dong)機(ji)和(he)電(dian)動(dong)(dong)機(ji)的工作(zuo)狀態，確保車(che)輛擁有(you)(you)最(zui)佳(jia)的燃油(you)經(jing)濟性表現(xian)。
