純(chun)電(dian)(dian)動(dong)汽(qi)車(che)，是(shi)指(zhi)以(yi)已充滿電(dian)(dian)的(de)(de)蓄電(dian)(dian)池(chi)供電(dian)(dian)給電(dian)(dian)動(dong)機，由電(dian)(dian)動(dong)機推(tui)動(dong)的(de)(de)車(che)輛，而(er)電(dian)(dian)池(chi)的(de)(de)電(dian)(dian)量由外部電(dian)(dian)源補充，并(bing)且符合道路(lu)交通、安全法規各項要求(qiu)的(de)(de)車(che)輛。

純電(dian)(dian)(dian)動(dong)汽車(che)完全由(you)可充電(dian)(dian)(dian)電(dian)(dian)(dian)池提供(gong)動(dong)力源的汽車(che)，由(you)于對環境(jing)影(ying)響相對傳統汽車(che)較小(xiao)，其前景被廣泛看好。

電(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)的(de)(de)組成包(bao)括：電(dian)(dian)(dian)(dian)力驅(qu)動(dong)(dong)及(ji)控(kong)(kong)制系統、驅(qu)動(dong)(dong)力傳(chuan)動(dong)(dong)等機(ji)械(xie)系統、完成既(ji)定任務的(de)(de)工作(zuo)裝(zhuang)置等。電(dian)(dian)(dian)(dian)力驅(qu)動(dong)(dong)及(ji)控(kong)(kong)制系統是(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)的(de)(de)核心，也是(shi)區別于內燃機(ji)汽(qi)(qi)車(che)的(de)(de)最(zui)大不同點。電(dian)(dian)(dian)(dian)力驅(qu)動(dong)(dong)及(ji)控(kong)(kong)制系統由驅(qu)動(dong)(dong)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)、電(dian)(dian)(dian)(dian)源(yuan)和電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)的(de)(de)調速(su)控(kong)(kong)制裝(zhuang)置等組成。電(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)的(de)(de)其他裝(zhuang)置基本與內燃機(ji)汽(qi)(qi)車(che)相同。
