一、混合動力轎車可以純電行駛嗎

混合動力汽車可以只用電(dian)，混(hun)合動(dong)力汽車可以分(fen)為三個(ge)種類，分(fen)別是(shi)插電(dian)式混(hun)合動(dong)力、油電(dian)混(hun)合動(dong)力以及增程(cheng)式混(hun)動(dong)，以下是(shi)詳(xiang)細的介(jie)紹(shao)：

插電式混合動力汽車：插電(dian)(dian)(dian)(dian)(dian)式混合動(dong)力汽車的電(dian)(dian)(dian)(dian)(dian)池相對(dui)比較大，可以外部充電(dian)(dian)(dian)(dian)(dian)，可以用純電(dian)(dian)(dian)(dian)(dian)模式行駛(shi)，電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)量耗盡后再以混合動(dong)力模式（以內(nei)燃機為主）行駛(shi)，并適時向電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)。

油電混合動力汽車：由(you)于油電(dian)(dian)混(hun)(hun)合(he)(he)動力(li)汽車的(de)電(dian)(dian)池容量較小，只需要在起步或停車，加速或減速時供應回收回收能(neng)量，所以不能(neng)純電(dian)(dian)模式下較長(chang)距離行(xing)駛。這是比較成熟的(de)一(yi)種類型混(hun)(hun)合(he)(he)動力(li)汽車。

增程式混合動力汽車：增程(cheng)式(shi)(shi)混(hun)合動(dong)(dong)(dong)力(li)(li)的原理是用發(fa)動(dong)(dong)(dong)機(ji)進(jin)行發(fa)電(dian)(dian)，電(dian)(dian)動(dong)(dong)(dong)機(ji)進(jin)行驅動(dong)(dong)(dong)的車(che)(che)輛(liang)。當電(dian)(dian)池(chi)(chi)組電(dian)(dian)量(liang)充(chong)(chong)足時采用純電(dian)(dian)動(dong)(dong)(dong)模式(shi)(shi)行駛(shi)，而當電(dian)(dian)量(liang)不足時，車(che)(che)內發(fa)動(dong)(dong)(dong)機(ji)啟動(dong)(dong)(dong)，帶動(dong)(dong)(dong)發(fa)電(dian)(dian)機(ji)為動(dong)(dong)(dong)力(li)(li)電(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)，提(ti)供電(dian)(dian)動(dong)(dong)(dong)機(ji)運行的電(dian)(dian)力(li)(li)（即(ji)增程(cheng)模式(shi)(shi)）。區別于插(cha)電(dian)(dian)式(shi)(shi)和油電(dian)(dian)混(hun)合動(dong)(dong)(dong)力(li)(li)，增程(cheng)式(shi)(shi)混(hun)合動(dong)(dong)(dong)力(li)(li)無(wu)論什么情況(kuang)下，都(dou)不能(neng)由發(fa)動(dong)(dong)(dong)機(ji)直接驅動(dong)(dong)(dong)車(che)(che)輪(lun)行駛(shi)，僅能(neng)通(tong)過(guo)(guo)電(dian)(dian)動(dong)(dong)(dong)機(ji)驅動(dong)(dong)(dong)。但它也能(neng)夠像插(cha)電(dian)(dian)式(shi)(shi)混(hun)合動(dong)(dong)(dong)力(li)(li)汽車(che)(che)—樣，通(tong)過(guo)(guo)外接電(dian)(dian)源進(jin)行充(chong)(chong)電(dian)(dian)。

二、動力混合汽車能跑長途嗎

動力混合汽車是可以長(chang)途行(xing)駛的(de)。混(hun)(hun)合動(dong)力車搭載了電(dian)機和動(dong)力電(dian)池(chi)，電(dian)機和電(dian)池(chi)的(de)電(dian)能完全由發(fa)動(dong)機提(ti)供，可作為燃油車使(shi)用。所以油電(dian)混(hun)(hun)合動(dong)力汽車跑長(chang)途是沒有問題的(de)。

另外，油(you)電(dian)混(hun)(hun)合動力高速(su)行駛用的是電(dian)還是油(you)，最好使用油(you)，因(yin)為混(hun)(hun)合動力汽(qi)車只有(you)在(zai)(zai)起(qi)步或低速(su)行駛時才使用電(dian)機(ji)驅(qu)(qu)動。汽(qi)車在(zai)(zai)高速(su)行駛時，以發動機(ji)驅(qu)(qu)動為主，電(dian)動機(ji)為輔。油(you)電(dian)混(hun)(hun)動車型的動力系統會(hui)根據不同情況(kuang)自由切換發動機(ji)和電(dian)動機(ji)的工作狀態，確保車輛(liang)擁有(you)最佳(jia)的燃油(you)經(jing)濟性表現。
