一、混合動力轎車可以純電行駛嗎

混合動力汽車可(ke)以(yi)只(zhi)用電(dian)，混(hun)(hun)合動(dong)力(li)汽車可(ke)以(yi)分為三個種類，分別(bie)是(shi)插電(dian)式(shi)混(hun)(hun)合動(dong)力(li)、油電(dian)混(hun)(hun)合動(dong)力(li)以(yi)及增程式(shi)混(hun)(hun)動(dong)，以(yi)下是(shi)詳細的介紹：

插電式混合動力汽車：插電(dian)(dian)(dian)式(shi)混(hun)合(he)動力汽車的電(dian)(dian)(dian)池相對(dui)比較(jiao)大，可(ke)以外部充(chong)電(dian)(dian)(dian)，可(ke)以用純電(dian)(dian)(dian)模式(shi)行駛，電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)耗盡(jin)后(hou)再(zai)以混(hun)合(he)動力模式(shi)（以內(nei)燃(ran)機為(wei)主）行駛，并(bing)適時(shi)向(xiang)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)。

油電混合動力汽車：由于油(you)電混(hun)合動力(li)(li)汽車(che)(che)的電池容(rong)量較(jiao)(jiao)小，只需要在起步或停(ting)車(che)(che)，加速或減速時(shi)供應(ying)回收回收能(neng)(neng)量，所以不(bu)能(neng)(neng)純(chun)電模式下(xia)較(jiao)(jiao)長距離行駛。這(zhe)是(shi)比較(jiao)(jiao)成熟的一種類型混(hun)合動力(li)(li)汽車(che)(che)。

增程式混合動力汽車：增程式混合動(dong)力(li)的原理是用發(fa)動(dong)機(ji)進(jin)行發(fa)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)動(dong)機(ji)進(jin)行驅動(dong)的車輛。當(dang)電(dian)(dian)(dian)(dian)池(chi)組電(dian)(dian)(dian)(dian)量(liang)充(chong)足時采用純電(dian)(dian)(dian)(dian)動(dong)模式行駛(shi)，而當(dang)電(dian)(dian)(dian)(dian)量(liang)不足時，車內(nei)發(fa)動(dong)機(ji)啟動(dong)，帶動(dong)發(fa)電(dian)(dian)(dian)(dian)機(ji)為動(dong)力(li)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)，提供電(dian)(dian)(dian)(dian)動(dong)機(ji)運行的電(dian)(dian)(dian)(dian)力(li)（即增程模式）。區別于插電(dian)(dian)(dian)(dian)式和油(you)電(dian)(dian)(dian)(dian)混合動(dong)力(li)，增程式混合動(dong)力(li)無論什么情況下(xia)，都不能由發(fa)動(dong)機(ji)直接(jie)驅動(dong)車輪行駛(shi)，僅(jin)能通過(guo)電(dian)(dian)(dian)(dian)動(dong)機(ji)驅動(dong)。但它(ta)也(ye)能夠像插電(dian)(dian)(dian)(dian)式混合動(dong)力(li)汽車—樣，通過(guo)外接(jie)電(dian)(dian)(dian)(dian)源進(jin)行充(chong)電(dian)(dian)(dian)(dian)。

二、動力混合汽車能跑長途嗎

動力混合汽車是可(ke)以長途行駛的。混合(he)動力(li)車(che)搭載了電(dian)機和(he)動力(li)電(dian)池，電(dian)機和(he)電(dian)池的電(dian)能完(wan)全由發動機提供(gong)，可(ke)作(zuo)為燃油(you)車(che)使用。所以油(you)電(dian)混合(he)動力(li)汽車(che)跑(pao)長途是沒有問題的。

另外，油電混(hun)合動(dong)(dong)力(li)高速(su)行駛用的是(shi)電還是(shi)油，最(zui)好使用油，因為(wei)混(hun)合動(dong)(dong)力(li)汽車(che)只有在起步或低速(su)行駛時才使用電機(ji)驅(qu)動(dong)(dong)。汽車(che)在高速(su)行駛時，以發(fa)動(dong)(dong)機(ji)驅(qu)動(dong)(dong)為(wei)主(zhu)，電動(dong)(dong)機(ji)為(wei)輔。油電混(hun)動(dong)(dong)車(che)型的動(dong)(dong)力(li)系統會根據不同情(qing)況(kuang)自由切換發(fa)動(dong)(dong)機(ji)和(he)電動(dong)(dong)機(ji)的工(gong)作狀態，確保(bao)車(che)輛擁有最(zui)佳的燃油經濟(ji)性表現。
