一、混合動力轎車可以純電行駛嗎

混合動力汽車可以(yi)只用電，混合動力汽(qi)車可以(yi)分為三個種類，分別是(shi)插電式混合動力、油電混合動力以(yi)及增程式混動，以(yi)下是(shi)詳細的介紹：

插電式混合動力汽車：插電(dian)(dian)式混合動(dong)(dong)力(li)汽(qi)車的電(dian)(dian)池(chi)(chi)相(xiang)對(dui)比較(jiao)大，可以外部充(chong)(chong)電(dian)(dian)，可以用純電(dian)(dian)模式行(xing)駛，電(dian)(dian)池(chi)(chi)電(dian)(dian)量耗盡后再以混合動(dong)(dong)力(li)模式（以內燃機為主）行(xing)駛，并適時(shi)向電(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)。

油電混合動力汽車：由于油電混(hun)合動力汽(qi)車(che)的電池容量較小，只需要在起(qi)步或(huo)停車(che)，加(jia)速或(huo)減(jian)速時供應回收(shou)回收(shou)能(neng)量，所(suo)以不能(neng)純電模(mo)式(shi)下較長距離行駛。這是比較成(cheng)熟的一種類型混(hun)合動力汽(qi)車(che)。

增程式混合動力汽車：增程式(shi)(shi)混(hun)合(he)動(dong)(dong)力的(de)原理是(shi)用發動(dong)(dong)機(ji)(ji)(ji)進行(xing)(xing)發電(dian)，電(dian)動(dong)(dong)機(ji)(ji)(ji)進行(xing)(xing)驅(qu)動(dong)(dong)的(de)車輛(liang)。當(dang)電(dian)池組電(dian)量充足時采用純電(dian)動(dong)(dong)模(mo)式(shi)(shi)行(xing)(xing)駛，而當(dang)電(dian)量不足時，車內(nei)發動(dong)(dong)機(ji)(ji)(ji)啟(qi)動(dong)(dong)，帶動(dong)(dong)發電(dian)機(ji)(ji)(ji)為動(dong)(dong)力電(dian)池充電(dian)，提供電(dian)動(dong)(dong)機(ji)(ji)(ji)運行(xing)(xing)的(de)電(dian)力（即增程模(mo)式(shi)(shi)）。區別于插電(dian)式(shi)(shi)和油(you)電(dian)混(hun)合(he)動(dong)(dong)力，增程式(shi)(shi)混(hun)合(he)動(dong)(dong)力無(wu)論什么(me)情況下(xia)，都(dou)不能由發動(dong)(dong)機(ji)(ji)(ji)直接(jie)驅(qu)動(dong)(dong)車輪行(xing)(xing)駛，僅能通(tong)(tong)過(guo)(guo)電(dian)動(dong)(dong)機(ji)(ji)(ji)驅(qu)動(dong)(dong)。但(dan)它也能夠像插電(dian)式(shi)(shi)混(hun)合(he)動(dong)(dong)力汽(qi)車—樣(yang)，通(tong)(tong)過(guo)(guo)外接(jie)電(dian)源進行(xing)(xing)充電(dian)。

二、動力混合汽車能跑長途嗎

動力混合汽車是(shi)可(ke)以長(chang)途行駛的。混(hun)(hun)合(he)動(dong)(dong)(dong)力車(che)搭載了電(dian)(dian)機(ji)和動(dong)(dong)(dong)力電(dian)(dian)池，電(dian)(dian)機(ji)和電(dian)(dian)池的電(dian)(dian)能完(wan)全(quan)由發(fa)動(dong)(dong)(dong)機(ji)提供(gong)，可(ke)作為燃油(you)車(che)使用。所以油(you)電(dian)(dian)混(hun)(hun)合(he)動(dong)(dong)(dong)力汽車(che)跑長(chang)途是(shi)沒有問(wen)題的。

另外，油電(dian)混合動(dong)(dong)(dong)力(li)高(gao)速(su)行駛用(yong)的(de)是(shi)電(dian)還是(shi)油，最好使用(yong)油，因為(wei)混合動(dong)(dong)(dong)力(li)汽(qi)車只有(you)在起步或(huo)低速(su)行駛時才(cai)使用(yong)電(dian)機(ji)驅(qu)動(dong)(dong)(dong)。汽(qi)車在高(gao)速(su)行駛時，以發(fa)動(dong)(dong)(dong)機(ji)驅(qu)動(dong)(dong)(dong)為(wei)主，電(dian)動(dong)(dong)(dong)機(ji)為(wei)輔。油電(dian)混動(dong)(dong)(dong)車型的(de)動(dong)(dong)(dong)力(li)系(xi)統會根據不同情況自由切換發(fa)動(dong)(dong)(dong)機(ji)和(he)電(dian)動(dong)(dong)(dong)機(ji)的(de)工作狀(zhuang)態，確(que)保車輛(liang)擁有(you)最佳的(de)燃油經濟(ji)性表現(xian)。
