時下購買電動自行車的消費者越來越多了，作為一種與日常生活聯系較緊，輕便、快捷、經濟型的代步工具，其關鍵部件如電池、電機、充電器的質量已成為人們相當關注的問題。

　　事(shi)實上，電(dian)動自行(xing)車(che)很早就(jiu)有了，但以前(qian)的電(dian)動自行(xing)車(che)僅僅是自行(xing)車(che)、電(dian)機、電(dian)池簡單(dan)疊加的“電(dian)瓶車(che)”，沒(mei)“風光”多久，這種性能和質量難(nan)以滿足(zu)人們出行(xing)基本要求的車(che)就(jiu)

被市(shi)場無情淘汰(tai)了(le)。上(shang)世(shi)紀(ji)90年代末，隨(sui)著(zhu)釹(nv)硼磁性(xing)稀(xi)土材料在直流電(dian)機(ji)上(shang)的(de)廣泛應用，特別(bie)是(shi)電(dian)池制(zhi)造技術的(de)進步(bu)以及工藝的(de)改(gai)善，市(shi)場上(shang)才出現了(le)真正(zheng)意義(yi)上(shang)的(de)電(dian)動自(zi)行(xing)車(che)。

　　然而(er)，由(you)于技(ji)術的(de)制約，長期以來，國產電(dian)(dian)(dian)(dian)動(dong)自行車應(ying)(ying)用(yong)的(de)均是普通鉛(qian)酸(suan)(suan)電(dian)(dian)(dian)(dian)池(chi)，該電(dian)(dian)(dian)(dian)池(chi)體積大、容量(liang)小、功率低(di)、壽(shou)命短，具有記(ji)憶效應(ying)(ying)，如日常使(shi)用(yong)就必須天(tian)天(tian)充(chong)電(dian)(dian)(dian)(dian)，且充(chong)電(dian)(dian)(dian)(dian)越(yue)頻電(dian)(dian)(dian)(dian)量(liang)越(yue)少(shao)；若長時間停用(yong)，則電(dian)(dian)(dian)(dian)池(chi)內部電(dian)(dian)(dian)(dian)極(ji)會迅速鈍化，要(yao)求(qiu)使(shi)用(yong)者(zhe)定(ding)期加入電(dian)(dian)(dian)(dian)解液(ye)維護(hu)保養，極(ji)其(qi)麻煩。更(geng)令人擔憂的(de)是，這種電(dian)(dian)(dian)(dian)池(chi)在(zai)報(bao)廢后(hou)其(qi)酸(suan)(suan)液(ye)和重金屬(shu)還(huan)會對(dui)(dui)環(huan)(huan)境造成(cheng)嚴重的(de)二次污(wu)染(ran)。針對(dui)(dui)這種情況，春蘭(lan)集團(tuan)研制出了容量(liang)和使(shi)用(yong)壽(shou)命分別比鉛(qian)酸(suan)(suan)電(dian)(dian)(dian)(dian)池(chi)高2倍、長4倍，全密封、免維護(hu)、無記(ji)憶的(de)高能動(dong)力鎳氫電(dian)(dian)(dian)(dian)池(chi)。此新型(xing)電(dian)(dian)(dian)(dian)池(chi)應(ying)(ying)用(yong)到電(dian)(dian)(dian)(dian)動(dong)自行車后(hou)，一(yi)次充(chong)電(dian)(dian)(dian)(dian)驅車續行里程最(zui)多達(da)100公里，循環(huan)(huan)充(chong)電(dian)(dian)(dian)(dian)最(zui)高達(da)600次。不僅其(qi)體積經特殊(shu)處理(li)及(ji)優化配方后(hou)進一(yi)步縮小，重量(liang)大幅減輕，而(er)且不存在(zai)對(dui)(dui)環(huan)(huan)境的(de)污(wu)染(ran)問題，因此，它是目前質(zhi)量(liang)最(zui)好(hao)的(de)動(dong)力型(xing)電(dian)(dian)(dian)(dian)池(chi)。

　　至于(yu)(yu)電機方面(mian)，市面(mian)上幾乎所有(you)品(pin)牌的(de)電動(dong)(dong)自(zi)行車(che)(che)采(cai)用的(de)都是(shi)較為先進的(de)有(you)刷(shua)無(wu)齒或(huo)是(shi)無(wu)刷(shua)直(zhi)流電機。據有(you)關(guan)媒體披(pi)露(lu)，春蘭今年新近推出(chu)的(de)電動(dong)(dong)自(zi)行車(che)(che)采(cai)用的(de)是(shi)世界最(zui)先進的(de)無(wu)刷(shua)直(zhi)流永磁電機，該電機由于(yu)(yu)沒(mei)有(you)傳(chuan)動(dong)(dong)齒輪，因此(ci)運行時沒(mei)有(you)噪音，也(ye)沒(mei)有(you)機械磨損，使用壽命更長。另外，春蘭電動(dong)(dong)自(zi)行車(che)(che)的(de)驅動(dong)(dong)電機安裝在車(che)(che)輪后軸(zhou)的(de)輪轂里(li)，直(zhi)接驅動(dong)(dong)后輪轉動(dong)(dong)，整體設計合理、結構緊湊，體積小、重量輕，從而傳(chuan)動(dong)(dong)效率相當高。

　　電(dian)(dian)動(dong)自行車的(de)另一個關鍵部件就是(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)器。國內不少廠家采用的(de)是(shi)(shi)簡便式(shi)充(chong)(chong)(chong)電(dian)(dian)器，這種充(chong)(chong)(chong)電(dian)(dian)器雖然充(chong)(chong)(chong)電(dian)(dian)比較(jiao)簡便，但容易(yi)造成充(chong)(chong)(chong)電(dian)(dian)不足或過(guo)量充(chong)(chong)(chong)電(dian)(dian)而損傷電(dian)(dian)池(chi)。春蘭(lan)提供的(de)是(shi)(shi)智能充(chong)(chong)(chong)電(dian)(dian)器，只(zhi)須接通電(dian)(dian)源，它會自動(dong)快速給電(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)，且電(dian)(dian)充(chong)(chong)(chong)滿(man)后(hou)會自動(dong)斷(duan)電(dian)(dian)，不存在充(chong)(chong)(chong)電(dian)(dian)不足或過(guo)量充(chong)(chong)(chong)電(dian)(dian)等問(wen)題(ti)。

　　除電池、電機、充電器外，電(dian)(dian)(dian)動(dong)(dong)車的控(kong)制(zhi)器(qi)也很(hen)重要(yao)。新近上市(shi)的春蘭電(dian)(dian)(dian)動(dong)(dong)自行(xing)車就(jiu)以(yi)當今先進的微(wei)電(dian)(dian)(dian)子(zi)技術為基(ji)礎，應用了具有多種(zhong)功(gong)能(neng)的控(kong)制(zhi)器(qi)，在此(ci)控(kong)制(zhi)器(qi)的控(kong)制(zhi)下，該車具備了為保(bao)護電(dian)(dian)(dian)池而設置(zhi)的欠壓(ya)保(bao)護、最大(da)電(dian)(dian)(dian)流(liu)限制(zhi)、靜啟動(dong)(dong)功(gong)能(neng)，以(yi)及電(dian)(dian)(dian)量提示、速(su)度(du)顯(xian)示等功(gong)能(neng)。

　　市場人士(shi)認為，盡管(guan)電(dian)(dian)(dian)動(dong)自行(xing)車(che)的性能、質(zhi)量存在著差異，但消費者只要選(xuan)擇(ze)有品牌信譽和生(sheng)產規模的專業廠家生(sheng)產的、配(pei)備了高質(zhi)量電(dian)(dian)(dian)池(chi)、電(dian)(dian)(dian)機和充電(dian)(dian)(dian)器的電(dian)(dian)(dian)動(dong)自行(xing)車(che)，就不必有什么憂慮了。
