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(xiang)當關(guan)注的問題。

　　事實上，電(dian)(dian)(dian)動自行(xing)車(che)很早就(jiu)有了，但(dan)以前的電(dian)(dian)(dian)動自行(xing)車(che)僅僅是自行(xing)車(che)、電(dian)(dian)(dian)機、電(dian)(dian)(dian)池簡單疊加的“電(dian)(dian)(dian)瓶車(che)”，沒“風光”多(duo)久，這種性能和質量(liang)難以滿足人們出行(xing)基(ji)本要求的車(che)就(jiu)

被市場無情淘汰(tai)了(le)。上(shang)(shang)世紀(ji)90年代末，隨著釹硼磁(ci)性稀土材料在(zai)直流電機上(shang)(shang)的(de)廣泛應用，特別是電池制(zhi)造技術的(de)進步以及工藝的(de)改(gai)善，市場上(shang)(shang)才出(chu)現了(le)真正(zheng)意(yi)義上(shang)(shang)的(de)電動自行車。

　　然(ran)而(er)，由于(yu)技術的(de)制(zhi)約(yue)，長(chang)(chang)期以(yi)來，國(guo)產電(dian)(dian)(dian)(dian)(dian)動(dong)自行車應(ying)用的(de)均是普通鉛酸電(dian)(dian)(dian)(dian)(dian)池(chi)，該(gai)電(dian)(dian)(dian)(dian)(dian)池(chi)體(ti)積大、容量(liang)(liang)(liang)小、功(gong)率低、壽命(ming)短，具有(you)記(ji)憶效應(ying)，如日常使用就必須天(tian)天(tian)充電(dian)(dian)(dian)(dian)(dian)，且充電(dian)(dian)(dian)(dian)(dian)越頻(pin)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)越少(shao)；若長(chang)(chang)時間停用，則電(dian)(dian)(dian)(dian)(dian)池(chi)內部電(dian)(dian)(dian)(dian)(dian)極(ji)會迅速鈍化(hua)，要求使用者定期加入(ru)電(dian)(dian)(dian)(dian)(dian)解液維(wei)護保養，極(ji)其(qi)麻(ma)煩。更令人擔憂的(de)是，這(zhe)種(zhong)電(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)(zai)報廢后(hou)(hou)其(qi)酸液和(he)重(zhong)金(jin)屬還會對(dui)環(huan)境造成嚴重(zhong)的(de)二次(ci)污染。針對(dui)這(zhe)種(zhong)情(qing)況(kuang)，春蘭(lan)集團研制(zhi)出(chu)了(le)容量(liang)(liang)(liang)和(he)使用壽命(ming)分別(bie)比鉛酸電(dian)(dian)(dian)(dian)(dian)池(chi)高(gao)2倍、長(chang)(chang)4倍，全密封、免維(wei)護、無記(ji)憶的(de)高(gao)能動(dong)力鎳氫電(dian)(dian)(dian)(dian)(dian)池(chi)。此(ci)新型電(dian)(dian)(dian)(dian)(dian)池(chi)應(ying)用到(dao)電(dian)(dian)(dian)(dian)(dian)動(dong)自行車后(hou)(hou)，一(yi)(yi)次(ci)充電(dian)(dian)(dian)(dian)(dian)驅車續行里(li)程最(zui)(zui)多(duo)達100公(gong)里(li)，循環(huan)充電(dian)(dian)(dian)(dian)(dian)最(zui)(zui)高(gao)達600次(ci)。不僅其(qi)體(ti)積經(jing)特殊處理及優(you)化(hua)配方后(hou)(hou)進一(yi)(yi)步縮小，重(zhong)量(liang)(liang)(liang)大幅減輕，而(er)且不存在(zai)(zai)對(dui)環(huan)境的(de)污染問題，因此(ci)，它是目前質量(liang)(liang)(liang)最(zui)(zui)好的(de)動(dong)力型電(dian)(dian)(dian)(dian)(dian)池(chi)。

　　至于(yu)電(dian)(dian)機(ji)(ji)(ji)方面(mian)，市面(mian)上幾乎所有(you)(you)品牌的(de)(de)電(dian)(dian)動(dong)(dong)自(zi)行車采用(yong)的(de)(de)都是較為(wei)先進的(de)(de)有(you)(you)刷(shua)無(wu)齒(chi)或是無(wu)刷(shua)直(zhi)流電(dian)(dian)機(ji)(ji)(ji)。據有(you)(you)關媒體(ti)(ti)披露，春蘭(lan)今年新近推出(chu)的(de)(de)電(dian)(dian)動(dong)(dong)自(zi)行車采用(yong)的(de)(de)是世界最先進的(de)(de)無(wu)刷(shua)直(zhi)流永磁電(dian)(dian)機(ji)(ji)(ji)，該電(dian)(dian)機(ji)(ji)(ji)由于(yu)沒有(you)(you)傳動(dong)(dong)齒(chi)輪(lun)，因此(ci)運(yun)行時沒有(you)(you)噪音，也沒有(you)(you)機(ji)(ji)(ji)械磨損，使用(yong)壽(shou)命(ming)更(geng)長(chang)。另(ling)外(wai)，春蘭(lan)電(dian)(dian)動(dong)(dong)自(zi)行車的(de)(de)驅動(dong)(dong)電(dian)(dian)機(ji)(ji)(ji)安裝在(zai)車輪(lun)后軸的(de)(de)輪(lun)轂(gu)里，直(zhi)接驅動(dong)(dong)后輪(lun)轉(zhuan)動(dong)(dong)，整體(ti)(ti)設計合理、結構緊湊，體(ti)(ti)積小、重量輕，從而傳動(dong)(dong)效率(lv)相(xiang)當高。

　　電(dian)(dian)動自(zi)(zi)行車的另一(yi)個(ge)關(guan)鍵部(bu)件(jian)就是充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)。國內不(bu)少廠家(jia)采用的是簡便(bian)式充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)，這種充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)雖然充(chong)(chong)(chong)電(dian)(dian)比較簡便(bian)，但容易(yi)造成充(chong)(chong)(chong)電(dian)(dian)不(bu)足(zu)或(huo)過量充(chong)(chong)(chong)電(dian)(dian)而損傷電(dian)(dian)池。春蘭提供的是智能(neng)充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)，只須接通電(dian)(dian)源(yuan)，它會自(zi)(zi)動快(kuai)速給電(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)，且(qie)電(dian)(dian)充(chong)(chong)(chong)滿后會自(zi)(zi)動斷電(dian)(dian)，不(bu)存在充(chong)(chong)(chong)電(dian)(dian)不(bu)足(zu)或(huo)過量充(chong)(chong)(chong)電(dian)(dian)等問題。

　　除電池、電機、充電器外，電(dian)(dian)(dian)動(dong)車(che)(che)的控(kong)制(zhi)器也很重(zhong)要。新近上市的春蘭(lan)電(dian)(dian)(dian)動(dong)自(zi)行車(che)(che)就以當今先進的微(wei)電(dian)(dian)(dian)子技術(shu)為基礎，應(ying)用(yong)了具有多種(zhong)功(gong)能(neng)的控(kong)制(zhi)器，在此控(kong)制(zhi)器的控(kong)制(zhi)下，該車(che)(che)具備了為保護(hu)電(dian)(dian)(dian)池而設置的欠壓(ya)保護(hu)、最大電(dian)(dian)(dian)流(liu)限制(zhi)、靜啟動(dong)功(gong)能(neng)，以及(ji)電(dian)(dian)(dian)量提示(shi)、速(su)度顯示(shi)等功(gong)能(neng)。

　　市(shi)場人士認為，盡管電動(dong)自行車的(de)性能、質量存在著差(cha)異(yi)，但消費(fei)者只要選擇有品牌信譽和生產(chan)規模(mo)的(de)專業廠(chang)家生產(chan)的(de)、配備了(le)高質量電池、電機(ji)和充電器的(de)電動(dong)自行車，就不必有什么憂慮(lv)了(le)。
