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，混合動(dong)力汽車(che)可以分為三個種(zhong)類(lei)，分別(bie)是插電式混合動(dong)力、油電混合動(dong)力以及增程式混動(dong)，以下是詳細的(de)介紹：

插電式混合動力汽車：插電(dian)式(shi)混(hun)合動力(li)汽車的電(dian)池(chi)(chi)相對(dui)比較大，可以外部充電(dian)，可以用純電(dian)模(mo)式(shi)行(xing)駛，電(dian)池(chi)(chi)電(dian)量(liang)耗(hao)盡后(hou)再(zai)以混(hun)合動力(li)模(mo)式(shi)（以內燃機為(wei)主）行(xing)駛，并適時向電(dian)池(chi)(chi)充電(dian)。

油電混合動力汽車：由于(yu)油電(dian)(dian)混合動力(li)(li)汽車的(de)(de)電(dian)(dian)池容(rong)量較(jiao)小，只需要(yao)在起步(bu)或停車，加速(su)或減速(su)時供應回收回收能量，所以不能純電(dian)(dian)模式下(xia)較(jiao)長距離(li)行駛。這是比較(jiao)成熟的(de)(de)一種(zhong)類(lei)型(xing)混合動力(li)(li)汽車。

增程式混合動力汽車：增(zeng)程(cheng)式混合(he)(he)動(dong)(dong)力(li)(li)的(de)原理是用發(fa)動(dong)(dong)機(ji)進行(xing)發(fa)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)進行(xing)驅動(dong)(dong)的(de)車(che)輛。當(dang)電(dian)(dian)(dian)(dian)池(chi)組(zu)電(dian)(dian)(dian)(dian)量充足時采用純(chun)電(dian)(dian)(dian)(dian)動(dong)(dong)模式行(xing)駛，而當(dang)電(dian)(dian)(dian)(dian)量不(bu)足時，車(che)內發(fa)動(dong)(dong)機(ji)啟(qi)動(dong)(dong)，帶動(dong)(dong)發(fa)電(dian)(dian)(dian)(dian)機(ji)為動(dong)(dong)力(li)(li)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)，提供(gong)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)運(yun)行(xing)的(de)電(dian)(dian)(dian)(dian)力(li)(li)（即(ji)增(zeng)程(cheng)模式）。區別于插(cha)(cha)電(dian)(dian)(dian)(dian)式和油電(dian)(dian)(dian)(dian)混合(he)(he)動(dong)(dong)力(li)(li)，增(zeng)程(cheng)式混合(he)(he)動(dong)(dong)力(li)(li)無論(lun)什么情況下(xia)，都不(bu)能由發(fa)動(dong)(dong)機(ji)直(zhi)接(jie)驅動(dong)(dong)車(che)輪(lun)行(xing)駛，僅(jin)能通過(guo)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)驅動(dong)(dong)。但它也能夠像插(cha)(cha)電(dian)(dian)(dian)(dian)式混合(he)(he)動(dong)(dong)力(li)(li)汽車(che)—樣，通過(guo)外(wai)接(jie)電(dian)(dian)(dian)(dian)源進行(xing)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)可以長途(tu)(tu)行駛的。混合動力(li)車(che)搭載了電(dian)(dian)機和動力(li)電(dian)(dian)池，電(dian)(dian)機和電(dian)(dian)池的電(dian)(dian)能(neng)完全由發動機提供，可作為燃油車(che)使用。所以油電(dian)(dian)混合動力(li)汽(qi)車(che)跑長途(tu)(tu)是(shi)沒有問題的。

另外，油(you)(you)(you)(you)電(dian)(dian)(dian)混(hun)合動(dong)力高速(su)行駛用的是電(dian)(dian)(dian)還是油(you)(you)(you)(you)，最(zui)(zui)好使用油(you)(you)(you)(you)，因為(wei)混(hun)合動(dong)力汽車(che)只有(you)在(zai)起步或低(di)速(su)行駛時才(cai)使用電(dian)(dian)(dian)機驅動(dong)。汽車(che)在(zai)高速(su)行駛時，以(yi)發動(dong)機驅動(dong)為(wei)主，電(dian)(dian)(dian)動(dong)機為(wei)輔。油(you)(you)(you)(you)電(dian)(dian)(dian)混(hun)動(dong)車(che)型(xing)的動(dong)力系(xi)統會根(gen)據不同情況自(zi)由(you)切換(huan)發動(dong)機和電(dian)(dian)(dian)動(dong)機的工(gong)作(zuo)狀(zhuang)態，確保車(che)輛擁(yong)有(you)最(zui)(zui)佳的燃油(you)(you)(you)(you)經濟性表現。
