廠家(jia)拼(pin)價格

　　專家介紹，電動車廠家生產的電動車電池一般由專業電池生產廠提供。不同品牌、不同廠家生產的電動車電池質量有優劣之別，價格當然也有高低之分。為了分食電動車市場這塊大“蛋糕”，一些廠家惡意競爭，在產品銷售上玩起了價格戰，而在生產環節中卻偷工減料，他們大多采用低價購進的劣質電動車電池。對此，專家提醒消費(fei)者，在購買電動自行車時，不能片(pian)面追求價格低(di)，而要選擇一些(xie)質量高、市場信譽度好(hao)的品(pin)牌(pai)。

　　商家賺黑錢

　　按照相關規定，電池作為電動車的主要部件，有相應的“三包”期。但從市場調查情況來看，有的電動車銷售人員既沒有電池維(wei)修的(de)(de)專業知(zhi)識，也沒(mei)有相關的(de)(de)專業檢測設備，對在“三包”期內出現故障的(de)(de)電(dian)(dian)池(chi)(chi)通常只加些電(dian)(dian)解(jie)液就(jiu)(jiu)算維(wei)護過(guo)了。等電(dian)(dian)池(chi)(chi)的(de)(de)“三包”期一(yi)過(guo)，就(jiu)(jiu)要(yao)消(xiao)費(fei)者(zhe)(zhe)掏腰包買新電(dian)(dian)池(chi)(chi)更(geng)(geng)(geng)換(huan)了。有的(de)(de)商家(jia)(jia)對電(dian)(dian)池(chi)(chi)質量問(wen)題干脆不(bu)認賬，以(yi)消(xiao)費(fei)者(zhe)(zhe)人(ren)為損壞為由，把責任向消(xiao)費(fei)者(zhe)(zhe)身(shen)上(shang)(shang)一(yi)推(tui)了之。更(geng)(geng)(geng)有甚者(zhe)(zhe)，有些商家(jia)(jia)表面上(shang)(shang)給消(xiao)費(fei)者(zhe)(zhe)更(geng)(geng)(geng)換(huan)新電(dian)(dian)池(chi)(chi)，卻將半舊的(de)(de)電(dian)(dian)池(chi)(chi)從(cong)外觀上(shang)(shang)進行技術處理，糊弄(nong)消(xiao)費(fei)者(zhe)(zhe)。暗(an)地里，他們以(yi)消(xiao)費(fei)者(zhe)(zhe)更(geng)(geng)(geng)換(huan)新電(dian)(dian)池(chi)(chi)的(de)(de)名(ming)義向廠家(jia)(jia)索要(yao)新電(dian)(dian)池(chi)(chi)，坐享其利，消(xiao)費(fei)者(zhe)(zhe)因此做了“冤大(da)頭”。

　　專(zhuan)家(jia)提醒首(shou)先，消(xiao)費(fei)者購買(mai)電(dian)動自(zi)行車要選擇有(you)固定(ding)維(wei)修點的商家(jia)或品牌，對電(dian)動車售后服務問題(ti)要與經(jing)營者事先約定(ding)。其次(ci)，電(dian)池(chi)“三包”是經(jing)營者的一種法定(ding)義務，電(dian)池(chi)在“三包”期(qi)內出(chu)現質量問題(ti)，要抓緊(jin)時間(jian)與商家(jia)協(xie)商解決或到相(xiang)關(guan)部門投訴。再次(ci)，接受維(wei)修、更(geng)換(huan)等處理時，一定(ding)要相(xiang)關(guan)人(ren)員在保(bao)修單(dan)上如實填寫，對更(geng)換(huan)的電(dian)池(chi)要進行認真查驗。

　　維護知識少

　　據了(le)解，一(yi)些消(xiao)費者在使用電(dian)(dian)(dian)池時存在方法不(bu)當問題(ti)。一(yi)是(shi)長時間(jian)充電(dian)(dian)(dian)，認為(wei)充得(de)時間(jian)越長電(dian)(dian)(dian)量越足(zu)。二是(shi)長時間(jian)虧電(dian)(dian)(dian)，電(dian)(dian)(dian)壓(ya)接(jie)近“紅線”車子(zi)跑不(bu)動了(le)才去充電(dian)(dian)(dian)。三是(shi)在溫(wen)度過(guo)高或過(guo)低的情況下充電(dian)(dian)(dian)。四是(shi)不(bu)注意電(dian)(dian)(dian)池的定期檢查(cha)、維護和保養(yang)。五(wu)是(shi)未按說明書要求進(jin)行正確操(cao)作。

　　專家提醒消費者，電池壽命長短除了與電池自身質量優劣有關外，還與消費者是否正確使用有關。長時間充電、長時間虧電及烈日下暴曬都會縮短電池使用壽命。如果電池溫度過低，電池就有可能存在充電接受能力差、充電不足問題。此外，在充電時，一定要檢查充電插座是否松動，線路之間是否碰線，所使用的充電器、電(dian)(dian)線直(zhi)徑(jing)、電(dian)(dian)壓(ya)等是否(fou)符合(he)電(dian)(dian)動車使用說(shuo)明書所規(gui)定(ding)的(de)要求。

　　廢電池隨意處理

　　電動車所用電池通常為鉛酸電池。據專業人士介紹，鉛酸電池主要由鉛(qian)、硫酸(suan)以及(ji)部分金屬(shu)及(ji)塑料組(zu)成(cheng)。廢(fei)電(dian)池(chi)酸(suan)液里含(han)有大(da)量的(de)鉛(qian)，隨(sui)(sui)意排放不但嚴重污(wu)染土壤和水源(yuan)，還會引發(fa)人體代謝、生殖及(ji)神經等(deng)方(fang)面的(de)疾病(bing)。相關(guan)部門明確要求，電(dian)動車銷(xiao)售行(xing)業必須做(zuo)好廢(fei)舊電(dian)池(chi)的(de)回收(shou)處(chu)理(li)工作。而在現實當(dang)中，有的(de)銷(xiao)售商把(ba)廢(fei)舊電(dian)池(chi)回收(shou)的(de)規定當(dang)成(cheng)耳邊風，導致(zhi)部分廢(fei)舊電(dian)池(chi)被“破爛王”收(shou)去。他們將廢(fei)舊電(dian)池(chi)內(nei)的(de)鉛(qian)酸(suan)溶液隨(sui)(sui)地傾倒，然后將電(dian)池(chi)內(nei)的(de)鉛(qian)等(deng)取出(chu)，賣給廢(fei)品(pin)收(shou)購站。

　　專家提醒消(xiao)費者(zhe)，目前全國每年(nian)產(chan)生的(de)電(dian)動車廢舊電(dian)池是(shi)一個不(bu)小(xiao)的(de)數目。保護環境，人人有責(ze)。一方面，經營者(zhe)要(yao)嚴格遵守行業規定，做好廢舊電(dian)池的(de)回收；另一方面，消(xiao)費者(zhe)切不(bu)可貪圖(tu)蠅頭小(xiao)利，將(jiang)廢舊電(dian)池賣給小(xiao)商(shang)小(xiao)販(fan)。

　　網商兵團：電(dian)動車蓄電(dian)池損壞原因大(da)揭秘

　　蓄(xu)電池壞損原因(yin)很(hen)復雜，大致(zhi)分(fen)為以下幾種(zhong)：

　　“過充”導致蓄電池壞損

　　“過充”首先是充電器的原因。目前的電動車充電器都有安全充電電壓設置，充電電壓一般設定在電瓶標準電壓的1.2倍以內，如48V的蓄電池，充電電壓設定在57.2V以內。蓄電池在放電過程中，電壓會逐步下降，當再次給電瓶充電時，充電器的紅燈會亮起，表示充電進行時，當電能不斷的輸入電瓶后，電壓會不斷升高，直至接近或等于充電電壓時充電器綠燈會亮起，此時，充(chong)電(dian)(dian)(dian)(dian)停(ting)止或涓流(liu)充(chong)電(dian)(dian)(dian)(dian)。如果(guo)充(chong)電(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)壓(ya)元件失靈，充(chong)電(dian)(dian)(dian)(dian)就(jiu)不(bu)會停(ting)止，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)會不(bu)間(jian)斷地輸入電(dian)(dian)(dian)(dian)瓶，電(dian)(dian)(dian)(dian)壓(ya)就(jiu)會不(bu)斷升高(gao)，電(dian)(dian)(dian)(dian)壓(ya)升高(gao)的結果(guo)就(jiu)會加劇電(dian)(dian)(dian)(dian)解液(ye)的熱反應，輕則蓄電(dian)(dian)(dian)(dian)池外殼會變形(膨(peng)脹)，重則致使蓄電(dian)(dian)(dian)(dian)池被(bei)充(chong)爆。

　　“虧電(dian)”導致(zhi)電(dian)瓶(ping)壞損

　　“虧電(dian)(dian)”是電(dian)(dian)池(chi)電(dian)(dian)量不足、電(dian)(dian)壓偏低時(shi)強行過量放電(dian)(dian)產生的(de)(de)一種破壞(huai)蓄電(dian)(dian)池(chi)極(ji)板涂層(ceng)的(de)(de)現象。很多用(yong)(yong)(yong)戶(hu)在使用(yong)(yong)(yong)電(dian)(dian)動車時(shi)往往是幾天充(chong)電(dian)(dian)一次，有(you)的(de)(de)每天行程(cheng)超過新電(dian)(dian)瓶(ping)標稱里程(cheng)的(de)(de)60%以(yi)上，要知道(dao)電(dian)(dian)池(chi)容量下降會導致蓄電(dian)(dian)池(chi)電(dian)(dian)壓不足(欠(qian)壓)，電(dian)(dian)壓不足就不能(neng)有(you)效的(de)(de)滿足車載電(dian)(dian)器基本的(de)(de)電(dian)(dian)壓供給，當電(dian)(dian)壓下降時(shi)，用(yong)(yong)(yong)戶(hu)還(huan)在使用(yong)(yong)(yong)電(dian)(dian)動車，而(er)蓄電(dian)(dian)池(chi)又不能(neng)提(ti)供正(zheng)常的(de)(de)電(dian)(dian)壓，因此就會因車載電(dian)(dian)器的(de)(de)負載使電(dian)(dian)瓶(ping)欠(qian)壓出現“虧電(dian)(dian)”，經常性的(de)(de)“虧電(dian)(dian)”就會使蓄電(dian)(dian)池(chi)極(ji)板鉛(qian)層(ceng)逐步剝離，直至(zhi)極(ji)板壞(huai)損。
