什麽(me)是(shi)電(dian)動(dong)汽車電(dian)機(ji)？

　　電(dian)動(dong)汽車電(dian)機(ji)電(dian)機(ji)電(dian)機(ji)是指以(yi)車載(zai)電(dian)源(yuan)為(wei)動(dong)力，用(yong)電(dian)機(ji)驅動車輪(lun)行駛，符(fu)合(he)道路(lu)交(jiao)通(tong)、安(an)全(quan)法(fa)規各(ge)項要(yao)求的車輛(liang)。由(you)於(yu)對(dui)環(huan)境(jing)影(ying)響(xiang)相(xiang)對(dui)傳統汽車較(jiao)小，其(qi)前景被廣泛看好(hao)，但當前(qian)技(ji)術(shu)尚(shang)不成(cheng)熟。電(dian)源(yuan)為(wei)電(dian)動(dong)汽車電(dian)機(ji)電(dian)機(ji)電(dian)機(ji)的驅動電(dian)動(dong)機提供電(dian)能(neng)，電(dian)動(dong)汽車電(dian)機(ji)電(dian)機(ji)電(dian)機(ji)電(dian)機(ji)將(jiang)電(dian)源(yuan)的電(dian)能(neng)轉化(hua)為(wei)機(ji)械能，通(tong)過傳動(dong)裝(zhuang)置(zhi)或直(zhi)接驅動(dong)車輪(lun)和工作裝(zhuang)置(zhi)。

　　由於電(dian)動(dong)汽車電(dian)機(ji)采用(yong)動力電(dian)池作(zuo)為(wei)車載(zai)能(neng)源(yuan)，其(qi)容量受(shou)到限制，為(wei)盡可能的延(yan)長(chang)續駛裏(li)程，大多數驅動系(xi)統都采用(yong)了能量回饋(kui)技術(shu)，即在汽車制動(dong)時，通(tong)過控制器(qi)將(jiang)車輪(lun)損(sun)耗(hao)的(de)動(dong)能(neng)反饋(kui)到電(dian)池中(zhong)，並使(shi)電(dian)機(ji)處(chu)於發(fa)電(dian)狀態，將(jiang)發(fa)出的電(dian)輸(shu)送到電(dian)池中(zhong)。因此(ci)，電(dian)動(dong)汽車電(dian)機(ji)的驅動機(ji)應(ying)該(gai)稱為(wei)電(dian)機(ji)，而不是我(wo)們(men)習(xi)慣稱呼的(de)電(dian)動(dong)機。
　　目(mu)前，電(dian)動(dong)汽車電(dian)機(ji)電(dian)機(ji)上應用(yong)比較(jiao)廣泛的(de)電(dian)源(yuan)是鉛(qian)酸蓄(xu)電(dian)池，但(dan)隨著(zhe)電(dian)動(dong)汽車電(dian)機(ji)電(dian)機(ji)技術(shu)的發(fa)展，鉛(qian)酸蓄(xu)電(dian)池由(you)於比能(neng)量較(jiao)低(di)，充(chong)電(dian)速(su)度較(jiao)慢，壽(shou)命(ming)較(jiao)短(duan)，逐(zhu)漸被其(qi)他蓄(xu)電(dian)池所(suo)取代(dai)。
