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(liang)已成為人們相當關注的問(wen)題。

　　事(shi)實(shi)上，電動自(zi)行(xing)車很早就(jiu)有(you)了，但以前的(de)電動自(zi)行(xing)車僅(jin)僅(jin)是(shi)自(zi)行(xing)車、電機、電池簡(jian)單疊加的(de)“電瓶車”，沒“風光(guang)”多久，這種(zhong)性能(neng)和質量(liang)難以滿足人(ren)們出行(xing)基(ji)本要求的(de)車就(jiu)

被市場無情(qing)淘(tao)汰了。上世紀90年(nian)代末，隨著釹硼磁性(xing)稀土材料在直流(liu)電機上的廣泛應用，特別是電池(chi)制造技(ji)術的進步以及工藝的改善，市場上才(cai)出現了真正意義(yi)上的電動自(zi)行車。

　　然而(er)，由(you)于(yu)技(ji)術的(de)(de)制約，長(chang)期以來，國(guo)產電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動自行車(che)應用的(de)(de)均(jun)是普(pu)通鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，該(gai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)體積大、容(rong)量小(xiao)、功率低、壽命短，具(ju)有(you)記憶(yi)效應，如日常使(shi)用就(jiu)必(bi)須天天充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，且充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)越(yue)頻(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量越(yue)少；若(ruo)長(chang)時(shi)間停用，則(ze)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)內部(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)會(hui)迅速鈍化，要求使(shi)用者定期加入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液(ye)(ye)維護(hu)保養，極(ji)其麻(ma)煩。更令人擔憂(you)的(de)(de)是，這(zhe)種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)報(bao)廢后(hou)其酸(suan)液(ye)(ye)和重金屬(shu)還(huan)會(hui)對環境(jing)造成嚴重的(de)(de)二(er)次污染(ran)(ran)。針對這(zhe)種情況(kuang)，春蘭集(ji)團研制出(chu)了(le)容(rong)量和使(shi)用壽命分別比鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)高2倍、長(chang)4倍，全(quan)密封、免維護(hu)、無記憶(yi)的(de)(de)高能(neng)動力(li)鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。此(ci)新型(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)應用到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動自行車(che)后(hou)，一次充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)驅車(che)續行里程最多(duo)達100公里，循環充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)最高達600次。不(bu)僅其體積經特殊處理及優化配方后(hou)進(jin)一步縮小(xiao)，重量大幅(fu)減輕，而(er)且不(bu)存在(zai)對環境(jing)的(de)(de)污染(ran)(ran)問題，因此(ci)，它是目前質(zhi)量最好的(de)(de)動力(li)型(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。

　　至于電(dian)(dian)機方面，市面上(shang)幾乎所有(you)品(pin)牌的(de)電(dian)(dian)動(dong)自行車采(cai)用的(de)都是較為(wei)先進的(de)有(you)刷無(wu)齒(chi)或是無(wu)刷直(zhi)流電(dian)(dian)機。據有(you)關媒(mei)體(ti)披(pi)露，春蘭今年(nian)新近推(tui)出的(de)電(dian)(dian)動(dong)自行車采(cai)用的(de)是世界最(zui)先進的(de)無(wu)刷直(zhi)流永(yong)磁(ci)電(dian)(dian)機，該電(dian)(dian)機由于沒(mei)有(you)傳動(dong)齒(chi)輪(lun)，因此運(yun)行時(shi)沒(mei)有(you)噪(zao)音，也(ye)沒(mei)有(you)機械磨損(sun)，使用壽命更長。另(ling)外，春蘭電(dian)(dian)動(dong)自行車的(de)驅(qu)動(dong)電(dian)(dian)機安裝(zhuang)在車輪(lun)后(hou)軸的(de)輪(lun)轂里，直(zhi)接驅(qu)動(dong)后(hou)輪(lun)轉動(dong)，整體(ti)設計合理、結構緊湊，體(ti)積小、重量輕，從(cong)而傳動(dong)效率(lv)相當高。

　　電(dian)(dian)(dian)(dian)(dian)動(dong)自行車(che)的另一個關鍵(jian)部件就是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。國內不(bu)少廠(chang)家采用(yong)的是(shi)簡便式充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)雖然充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)比較簡便，但容(rong)易造成充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)不(bu)足或過量充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)而損傷電(dian)(dian)(dian)(dian)(dian)池。春(chun)蘭提(ti)供的是(shi)智能(neng)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，只須接通電(dian)(dian)(dian)(dian)(dian)源，它會(hui)自動(dong)快速給(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，且電(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)滿(man)后會(hui)自動(dong)斷電(dian)(dian)(dian)(dian)(dian)，不(bu)存在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)不(bu)足或過量充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)等問題。

　　除電池、電機、充電器外，電(dian)動車(che)的(de)控(kong)制(zhi)器也很重要。新近上市的(de)春(chun)蘭電(dian)動自行(xing)車(che)就(jiu)以(yi)(yi)當今先(xian)進的(de)微電(dian)子技術為(wei)基(ji)礎，應(ying)用(yong)了具有(you)多種(zhong)功能(neng)的(de)控(kong)制(zhi)器，在(zai)此(ci)控(kong)制(zhi)器的(de)控(kong)制(zhi)下(xia)，該(gai)車(che)具備(bei)了為(wei)保護電(dian)池而(er)設置的(de)欠壓保護、最大電(dian)流限制(zhi)、靜啟(qi)動功能(neng)，以(yi)(yi)及電(dian)量提(ti)示(shi)、速度(du)顯示(shi)等功能(neng)。

　　市場人士認為(wei)，盡(jin)管電(dian)動(dong)自行車(che)(che)的(de)性能、質量存在著差(cha)異(yi)，但消費者(zhe)只要選(xuan)擇(ze)有品牌信譽和(he)生產(chan)規模的(de)專業廠家生產(chan)的(de)、配備了高(gao)質量電(dian)池(chi)、電(dian)機和(he)充電(dian)器(qi)的(de)電(dian)動(dong)自行車(che)(che)，就不必有什么(me)憂慮了。
