插電(dian)式(shi)(shi)混合動力電(dian)動汽車的工作模式(shi)(shi)與重(zhong)慶增程器(qi)非常相似。它(ta)們都(dou)可(ke)以(yi)通(tong)過(guo)動(dong)(dong)力鋰電(dian)池獨(du)立輸入動(dong)(dong)能(neng)，以(yi)純電(dian)動(dong)(dong)汽車模(mo)式驅(qu)動(dong)(dong)。當(dang)驅(qu)動(dong)(dong)動(dong)(dong)力電(dian)池的(de)功(gong)率接近設定的(de)下限時(shi)，它(ta)們被切換到另一個動(dong)(dong)力裝置，以(yi)再次提供車輛(liang)所需的(de)動(dong)(dong)能(neng)。然而(er)，兩者(zhe)在工作(zuo)原(yuan)則(ze)上有著本質的(de)區別。

增程電動汽車(che)是在(zai)純電動汽車(che)的基礎上(shang)發展起來的一種電動汽車(che)。它通常被稱為range extender electric vehicle，因為range extender被添加到(dao)車輛中(zhong)，而將range extender添加到車輛(liang)中的(de)效(xiao)果是進一步(bu)提高純(chun)電(dian)(dian)(dian)動車輛(liang)的(de)里程數，從而(er)將(jiang)重復(fu)停車蓄電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)降(jiang)至最低。

插電(dian)式混(hun)(hun)合動(dong)(dong)(dong)力(li)(li)電(dian)動(dong)(dong)(dong)汽車(che)是由(you)混(hun)(hun)合動(dong)(dong)(dong)力(li)(li)電(dian)動(dong)(dong)(dong)汽車(che)發(fa)展而來的(de)。它(ta)具(ju)有(you)混(hun)(hun)合動(dong)(dong)(dong)力(li)(li)電(dian)動(dong)(dong)(dong)汽車(che)的(de)大(da)部分(fen)特點(dian)，但是混(hun)(hun)合動(dong)(dong)(dong)力(li)(li)電(dian)動(dong)(dong)(dong)汽車(che)的(de)輸出功率可充電(dian)電(dian)池被更(geng)大(da)容(rong)量的(de)動(dong)(dong)(dong)能可充電(dian)電(dian)池（動(dong)(dong)(dong)能包含在企業質量中）所取代(dai)，這樣，動(dong)(dong)(dong)力(li)(li)鋰電(dian)池將具(ju)有(you)足夠的(de)動(dong)(dong)(dong)能，以(yi)確保里程延(yan)長器能夠在零排(pai)放、無燃(ran)油消(xiao)耗的(de)純電(dian)動(dong)(dong)(dong)模式下行駛(shi)一定距離。
