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(de)質量已(yi)成(cheng)為人(ren)們相當(dang)關注的(de)問題。

　　事實上，電(dian)動自行車(che)很(hen)早就(jiu)(jiu)有了，但以(yi)前的電(dian)動自行車(che)僅(jin)僅(jin)是(shi)自行車(che)、電(dian)機、電(dian)池(chi)簡單疊加的“電(dian)瓶車(che)”，沒(mei)“風光”多(duo)久(jiu)，這種性能和質(zhi)量難以(yi)滿(man)足人(ren)們出行基本要求的車(che)就(jiu)(jiu)

被市場(chang)無情淘汰了(le)。上(shang)世紀(ji)90年代末，隨著釹硼磁(ci)性稀土材料(liao)在直流電(dian)機上(shang)的(de)(de)廣泛應用，特別(bie)是電(dian)池制造技術的(de)(de)進步以(yi)及(ji)工藝(yi)的(de)(de)改善，市場(chang)上(shang)才(cai)出現了(le)真正意義上(shang)的(de)(de)電(dian)動(dong)自行車。

　　然而(er)，由于技術的(de)(de)制(zhi)約，長期(qi)以來，國產電(dian)(dian)(dian)(dian)動自行車應用(yong)的(de)(de)均是(shi)(shi)普通鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)池(chi)(chi)，該電(dian)(dian)(dian)(dian)池(chi)(chi)體(ti)積大、容(rong)(rong)量(liang)(liang)(liang)小、功率低、壽命短，具有記憶(yi)效(xiao)應，如日常(chang)使用(yong)就(jiu)必須天天充電(dian)(dian)(dian)(dian)，且充電(dian)(dian)(dian)(dian)越頻電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)越少；若長時間停(ting)用(yong)，則電(dian)(dian)(dian)(dian)池(chi)(chi)內部(bu)電(dian)(dian)(dian)(dian)極會迅速鈍化，要(yao)求使用(yong)者定(ding)期(qi)加入(ru)電(dian)(dian)(dian)(dian)解(jie)液維護(hu)保養，極其(qi)麻煩(fan)。更(geng)令人擔(dan)憂的(de)(de)是(shi)(shi)，這種電(dian)(dian)(dian)(dian)池(chi)(chi)在(zai)報廢(fei)后其(qi)酸(suan)液和重(zhong)(zhong)金屬還會對(dui)(dui)環境(jing)造(zao)成嚴重(zhong)(zhong)的(de)(de)二次污染(ran)。針對(dui)(dui)這種情(qing)況，春蘭集團研制(zhi)出(chu)了(le)容(rong)(rong)量(liang)(liang)(liang)和使用(yong)壽命分別比鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)池(chi)(chi)高2倍(bei)、長4倍(bei)，全密(mi)封(feng)、免維護(hu)、無(wu)記憶(yi)的(de)(de)高能動力鎳(nie)氫電(dian)(dian)(dian)(dian)池(chi)(chi)。此新型(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)應用(yong)到(dao)電(dian)(dian)(dian)(dian)動自行車后，一(yi)次充電(dian)(dian)(dian)(dian)驅(qu)車續行里程最(zui)(zui)多達100公里，循環充電(dian)(dian)(dian)(dian)最(zui)(zui)高達600次。不僅其(qi)體(ti)積經特(te)殊處理及(ji)優化配方(fang)后進一(yi)步縮(suo)小，重(zhong)(zhong)量(liang)(liang)(liang)大幅(fu)減輕，而(er)且不存在(zai)對(dui)(dui)環境(jing)的(de)(de)污染(ran)問題，因此，它是(shi)(shi)目(mu)前質量(liang)(liang)(liang)最(zui)(zui)好的(de)(de)動力型(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)。

　　至于(yu)電機(ji)方面(mian)，市(shi)面(mian)上(shang)幾乎(hu)所有(you)品牌的(de)電動(dong)(dong)(dong)自行(xing)車采用的(de)都是(shi)較(jiao)為先(xian)進的(de)有(you)刷(shua)無(wu)齒(chi)或是(shi)無(wu)刷(shua)直流電機(ji)。據有(you)關媒體(ti)披(pi)露，春蘭(lan)今年(nian)新近推出(chu)的(de)電動(dong)(dong)(dong)自行(xing)車采用的(de)是(shi)世(shi)界最先(xian)進的(de)無(wu)刷(shua)直流永磁電機(ji)，該電機(ji)由于(yu)沒有(you)傳動(dong)(dong)(dong)齒(chi)輪(lun)(lun)，因此運行(xing)時(shi)沒有(you)噪音，也(ye)沒有(you)機(ji)械磨損，使用壽命更長。另(ling)外，春蘭(lan)電動(dong)(dong)(dong)自行(xing)車的(de)驅(qu)動(dong)(dong)(dong)電機(ji)安裝在(zai)車輪(lun)(lun)后(hou)軸的(de)輪(lun)(lun)轂(gu)里，直接驅(qu)動(dong)(dong)(dong)后(hou)輪(lun)(lun)轉動(dong)(dong)(dong)，整(zheng)體(ti)設計合理、結構緊湊，體(ti)積小、重量輕，從而傳動(dong)(dong)(dong)效率相當高。

　　電(dian)(dian)(dian)(dian)(dian)(dian)動自(zi)行(xing)車的另一個關鍵部(bu)件就是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。國內不少廠家采用(yong)的是簡便式充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)雖然充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)比較(jiao)簡便，但容易(yi)造成充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)不足或過(guo)量充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)而損傷(shang)電(dian)(dian)(dian)(dian)(dian)(dian)池。春蘭(lan)提供的是智能充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，只須接(jie)通電(dian)(dian)(dian)(dian)(dian)(dian)源，它會自(zi)動快(kuai)速給電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，且電(dian)(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)滿后會自(zi)動斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，不存在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)不足或過(guo)量充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)等問題。

　　除電池、電機、充電器外(wai)，電(dian)(dian)動車(che)的(de)控(kong)制器也很重要。新近(jin)上市的(de)春蘭(lan)電(dian)(dian)動自行車(che)就以(yi)當今(jin)先進(jin)的(de)微電(dian)(dian)子(zi)技術為基礎(chu)，應(ying)用(yong)了具有多種(zhong)功能的(de)控(kong)制器，在此控(kong)制器的(de)控(kong)制下，該車(che)具備了為保(bao)護電(dian)(dian)池而設置的(de)欠壓(ya)保(bao)護、最大電(dian)(dian)流限制、靜啟動功能，以(yi)及電(dian)(dian)量(liang)提示、速度(du)顯示等功能。

　　市場人士認為，盡(jin)管(guan)電動自(zi)行(xing)車(che)的(de)性(xing)能、質(zhi)量存在著差異(yi)，但(dan)消費者只(zhi)要選擇有品牌信(xin)譽和(he)生產(chan)規(gui)模的(de)專業廠家生產(chan)的(de)、配備(bei)了(le)高質(zhi)量電池、電機和(he)充電器(qi)的(de)電動自(zi)行(xing)車(che)，就不必有什么憂慮了(le)。
