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。

　　事實上，電(dian)(dian)動自(zi)行車很早就有了，但以前的電(dian)(dian)動自(zi)行車僅僅是自(zi)行車、電(dian)(dian)機(ji)、電(dian)(dian)池簡單疊加的“電(dian)(dian)瓶車”，沒“風光(guang)”多久(jiu)，這種性能和質(zhi)量難以滿足人們(men)出(chu)行基本要求的車就

被市場無情淘汰了。上(shang)世紀(ji)90年代末，隨著釹硼磁性稀土材料在直流電機上(shang)的廣泛應用，特(te)別(bie)是電池制造技(ji)術的進步以及工藝的改(gai)善(shan)，市場上(shang)才(cai)出現了真正意義上(shang)的電動自行車(che)。

　　然而，由于技術的(de)(de)制(zhi)約，長(chang)期以來，國產電(dian)(dian)(dian)(dian)動自行車(che)應用的(de)(de)均是(shi)普通鉛酸(suan)電(dian)(dian)(dian)(dian)池(chi)，該電(dian)(dian)(dian)(dian)池(chi)體積大、容(rong)量(liang)小、功率低、壽命短(duan)，具有記憶效應，如日常使用就必須天天充(chong)電(dian)(dian)(dian)(dian)，且充(chong)電(dian)(dian)(dian)(dian)越(yue)(yue)頻電(dian)(dian)(dian)(dian)量(liang)越(yue)(yue)少(shao)；若長(chang)時間停用，則電(dian)(dian)(dian)(dian)池(chi)內部電(dian)(dian)(dian)(dian)極(ji)(ji)會(hui)迅速鈍化，要求使用者定期加入電(dian)(dian)(dian)(dian)解液(ye)維護保養，極(ji)(ji)其(qi)麻煩。更令人擔憂的(de)(de)是(shi)，這種(zhong)電(dian)(dian)(dian)(dian)池(chi)在報(bao)廢后其(qi)酸(suan)液(ye)和(he)重(zhong)金屬還會(hui)對(dui)環(huan)境(jing)造成嚴重(zhong)的(de)(de)二次污(wu)染(ran)。針對(dui)這種(zhong)情況(kuang)，春蘭集團研制(zhi)出了容(rong)量(liang)和(he)使用壽命分別比鉛酸(suan)電(dian)(dian)(dian)(dian)池(chi)高2倍(bei)、長(chang)4倍(bei)，全密封、免維護、無記憶的(de)(de)高能(neng)動力(li)(li)鎳氫電(dian)(dian)(dian)(dian)池(chi)。此(ci)(ci)新型(xing)電(dian)(dian)(dian)(dian)池(chi)應用到(dao)電(dian)(dian)(dian)(dian)動自行車(che)后，一次充(chong)電(dian)(dian)(dian)(dian)驅車(che)續(xu)行里程(cheng)最(zui)多達100公里，循環(huan)充(chong)電(dian)(dian)(dian)(dian)最(zui)高達600次。不僅(jin)其(qi)體積經特(te)殊(shu)處理及優(you)化配方后進一步縮小，重(zhong)量(liang)大幅(fu)減輕，而且不存(cun)在對(dui)環(huan)境(jing)的(de)(de)污(wu)染(ran)問題，因此(ci)(ci)，它是(shi)目前質(zhi)量(liang)最(zui)好的(de)(de)動力(li)(li)型(xing)電(dian)(dian)(dian)(dian)池(chi)。

　　至于(yu)電(dian)(dian)(dian)機方面，市面上幾乎所有(you)(you)(you)品牌的(de)電(dian)(dian)(dian)動自行(xing)(xing)車(che)采用的(de)都是(shi)較為(wei)先進的(de)有(you)(you)(you)刷無齒或(huo)是(shi)無刷直(zhi)流電(dian)(dian)(dian)機。據有(you)(you)(you)關(guan)媒體(ti)(ti)披(pi)露，春蘭(lan)今年新近(jin)推出的(de)電(dian)(dian)(dian)動自行(xing)(xing)車(che)采用的(de)是(shi)世(shi)界(jie)最先進的(de)無刷直(zhi)流永磁電(dian)(dian)(dian)機，該(gai)電(dian)(dian)(dian)機由于(yu)沒(mei)有(you)(you)(you)傳動齒輪(lun)(lun)，因(yin)此運行(xing)(xing)時(shi)沒(mei)有(you)(you)(you)噪音，也(ye)沒(mei)有(you)(you)(you)機械磨損(sun)，使用壽命更長。另外(wai)，春蘭(lan)電(dian)(dian)(dian)動自行(xing)(xing)車(che)的(de)驅動電(dian)(dian)(dian)機安裝在車(che)輪(lun)(lun)后(hou)軸的(de)輪(lun)(lun)轂里，直(zhi)接驅動后(hou)輪(lun)(lun)轉動，整體(ti)(ti)設計合理、結構緊湊，體(ti)(ti)積小、重(zhong)量(liang)輕，從而傳動效率相當(dang)高。

　　電(dian)(dian)(dian)(dian)(dian)動自(zi)行(xing)車的另一個關鍵部(bu)件就是(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。國內不(bu)(bu)少廠家(jia)采用的是(shi)簡便式(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，這(zhe)種充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)雖(sui)然充(chong)電(dian)(dian)(dian)(dian)(dian)比較簡便，但容易造成充(chong)電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)足或過量(liang)充(chong)電(dian)(dian)(dian)(dian)(dian)而損傷電(dian)(dian)(dian)(dian)(dian)池(chi)。春(chun)蘭(lan)提供的是(shi)智能充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，只須接通電(dian)(dian)(dian)(dian)(dian)源(yuan)，它會(hui)自(zi)動快速給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，且(qie)電(dian)(dian)(dian)(dian)(dian)充(chong)滿后會(hui)自(zi)動斷(duan)電(dian)(dian)(dian)(dian)(dian)，不(bu)(bu)存在充(chong)電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)足或過量(liang)充(chong)電(dian)(dian)(dian)(dian)(dian)等問題。

　　除電池、電機、充電器外(wai)，電(dian)動(dong)(dong)車的(de)(de)控(kong)制器(qi)(qi)也(ye)很重要。新近上市的(de)(de)春蘭電(dian)動(dong)(dong)自行車就以當今先進的(de)(de)微電(dian)子技術為(wei)基礎，應用了具(ju)有多種功(gong)(gong)能的(de)(de)控(kong)制器(qi)(qi)，在此(ci)控(kong)制器(qi)(qi)的(de)(de)控(kong)制下，該車具(ju)備了為(wei)保(bao)護電(dian)池而(er)設置的(de)(de)欠壓(ya)保(bao)護、最大電(dian)流限制、靜啟動(dong)(dong)功(gong)(gong)能，以及電(dian)量提示(shi)(shi)、速度顯示(shi)(shi)等功(gong)(gong)能。

　　市場人士認為(wei)，盡管電(dian)動自行車的(de)性能、質(zhi)(zhi)量(liang)(liang)存在(zai)著差(cha)異(yi)，但消費者(zhe)只要選擇有品牌(pai)信譽和(he)生(sheng)產規模的(de)專(zhuan)業(ye)廠家生(sheng)產的(de)、配備了(le)高質(zhi)(zhi)量(liang)(liang)電(dian)池、電(dian)機(ji)和(he)充(chong)電(dian)器的(de)電(dian)動自行車，就(jiu)不必(bi)有什么憂慮(lv)了(le)。
