一、油電混合車是什么意思

油電混合車一般指油(you)(you)電(dian)(dian)混合動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)汽(qi)車，即燃料（汽(qi)油(you)(you)，柴油(you)(you)）和(he)電(dian)(dian)能(neng)的(de)(de)(de)混合，是由(you)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)馬達(da)作為(wei)發(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)輔助動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)汽(qi)車，屬于(yu)一種優勢互補的(de)(de)(de)技術(shu)，也可以(yi)歸結(jie)(jie)為(wei)集成創新，拿主(zhu)流(liu)的(de)(de)(de)混合動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)技術(shu)來言(yan)，動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)源(yuan)主(zhu)要(yao)是發(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，然后配備了第二個(ge)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)源(yuan)電(dian)(dian)池，這二者結(jie)(jie)合起來進行節能(neng)，輔助發(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)馬達(da)可以(yi)在(zai)正常行駛中(zhong)產生強大(da)而平穩(wen)的(de)(de)(de)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)。在(zai)起步、加(jia)速(su)時，又由(you)于(yu)有電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)馬達(da)的(de)(de)(de)輔助，所以(yi)可以(yi)降低油(you)(you)耗，簡單地說，就是與同樣大(da)小的(de)(de)(de)汽(qi)車相比，燃油(you)(you)費(fei)用(yong)更低。因此，車主(zhu)可以(yi)享受更強勁的(de)(de)(de)起步、加(jia)速(su)同時還能(neng)實現(xian)較(jiao)高(gao)水平的(de)(de)(de)燃油(you)(you)經濟性(xing)。

二、油電混動汽車的優缺點

優點

1、和(he)汽(qi)油車一樣(yang)到(dao)加(jia)油站加(jia)油，不(bu)用改變(bian)汽(qi)車的使用習(xi)慣；政府和(he)企業推廣這種產品也無須投資新建充電裝置(zhi)或加(jia)氣站。

2、燃油經濟性能高，而且行駛性能優越，油電混合動力汽車的(de)發動機要使用燃(ran)油，而且在起(qi)步、加(jia)速時，由于有(you)電動馬達(da)的(de)輔助(zhu)，所以(yi)可以(yi)降低(di)油耗(hao)，可關停內燃(ran)機，由電池(chi)單獨驅動，實現(xian)"零"排放。

3、動力性優于同排量(liang)的單(dan)純內(nei)(nei)燃機(ji)汽車，特別(bie)是在(zai)起步加速(su)時，電(dian)動機(ji)可以(yi)有(you)效地彌(mi)補內(nei)(nei)燃機(ji)低轉速(su)扭矩力不足的弱點(dian)。

4、減少車(che)內的機械噪(zao)音、低速或怠速時采(cai)用電動機工作。

缺點

1、技(ji)術不(bu)成(cheng)熟，相關(guan)產品定價(jia)過(guo)高(gao)，電動機和內燃機兩(liang)套(tao)動力(li)系統的造價(jia)遠比一套(tao)動力(li)系統的成(cheng)本(ben)高(gao)。

2、長時(shi)間(jian)(jian)高速(su)或勻速(su)行(xing)駛(shi)不(bu)省(sheng)油。因為混合動(dong)力(li)(li)車(che)燃油消耗上的優勢主要依(yi)靠(kao)勢能(neng)積蓄電力(li)(li)節能(neng)，換句(ju)話說，混合動(dong)力(li)(li)車(che)在行(xing)駛(shi)中(zhong)越是頻(pin)繁制動(dong)減速(su)、或頻(pin)繁地起(qi)步停車(che)就會相對更為節能(neng)。而如果處于(yu)長時(shi)間(jian)(jian)勻速(su)行(xing)駛(shi)，其節能(neng)效果就會相應降(jiang)低。
