廠家拼(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(ti)醒消費者，在(zai)購買電(dian)動自行車時，不能片面追求價格低，而(er)要(yao)選擇一些質量高(gao)、市(shi)場信(xin)譽度好的品(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修的專業知識，也沒(mei)有(you)相(xiang)關的專業檢測設備，對(dui)在(zai)“三包”期內出(chu)現(xian)故障(zhang)的電池(chi)通(tong)常只(zhi)加些電解(jie)液就(jiu)算維護(hu)過(guo)了(le)(le)。等電池(chi)的“三包”期一過(guo)，就(jiu)要(yao)消(xiao)費(fei)者(zhe)(zhe)(zhe)掏腰包買新(xin)(xin)電池(chi)更(geng)換(huan)了(le)(le)。有(you)的商家(jia)對(dui)電池(chi)質量問題干脆不認(ren)賬，以消(xiao)費(fei)者(zhe)(zhe)(zhe)人為損壞為由，把(ba)責任向(xiang)消(xiao)費(fei)者(zhe)(zhe)(zhe)身上(shang)一推了(le)(le)之(zhi)。更(geng)有(you)甚者(zhe)(zhe)(zhe)，有(you)些商家(jia)表面上(shang)給(gei)消(xiao)費(fei)者(zhe)(zhe)(zhe)更(geng)換(huan)新(xin)(xin)電池(chi)，卻將半(ban)舊的電池(chi)從(cong)外(wai)觀上(shang)進行技術(shu)處理(li)，糊弄消(xiao)費(fei)者(zhe)(zhe)(zhe)。暗地里，他們以消(xiao)費(fei)者(zhe)(zhe)(zhe)更(geng)換(huan)新(xin)(xin)電池(chi)的名義向(xiang)廠家(jia)索(suo)要(yao)新(xin)(xin)電池(chi)，坐(zuo)享(xiang)其利，消(xiao)費(fei)者(zhe)(zhe)(zhe)因此做了(le)(le)“冤大頭”。

　　專家提醒首(shou)先(xian)，消(xiao)費者(zhe)購(gou)買電(dian)動自行車(che)要(yao)(yao)選擇有固定(ding)(ding)維修點的商(shang)家或品牌，對(dui)電(dian)動車(che)售后服務問(wen)題要(yao)(yao)與經營(ying)者(zhe)事先(xian)約定(ding)(ding)。其次(ci)，電(dian)池(chi)“三包”是經營(ying)者(zhe)的一種(zhong)法定(ding)(ding)義務，電(dian)池(chi)在(zai)“三包”期內出現(xian)質量問(wen)題，要(yao)(yao)抓緊時間與商(shang)家協商(shang)解決(jue)或到相關(guan)部門(men)投訴。再次(ci)，接受維修、更換(huan)等處理時，一定(ding)(ding)要(yao)(yao)相關(guan)人員(yuan)在(zai)保(bao)修單上(shang)如實填寫，對(dui)更換(huan)的電(dian)池(chi)要(yao)(yao)進行認真(zhen)查驗。

　　維護知識少

　　據了(le)解，一些消費者在使用(yong)電(dian)(dian)池時存在方法不(bu)當問題(ti)。一是(shi)長時間充(chong)電(dian)(dian)，認為充(chong)得時間越長電(dian)(dian)量越足。二(er)是(shi)長時間虧電(dian)(dian)，電(dian)(dian)壓接近“紅線”車子跑不(bu)動了(le)才去充(chong)電(dian)(dian)。三是(shi)在溫度過(guo)高或過(guo)低的情況下(xia)充(chong)電(dian)(dian)。四是(shi)不(bu)注意電(dian)(dian)池的定期檢查、維(wei)護和(he)保養。五(wu)是(shi)未按說明書要求進行正(zheng)確操作(zuo)。

　　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、電線直徑、電壓(ya)等是否符合(he)電動車使用說(shuo)明書所規定的要(yao)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(zhu)要由鉛(qian)(qian)、硫酸(suan)以及部分(fen)金屬及塑料組成(cheng)(cheng)。廢(fei)電池酸(suan)液(ye)里(li)含有(you)大量的(de)鉛(qian)(qian)，隨(sui)意排放不(bu)但嚴重污染土壤和水(shui)源，還會(hui)引發人體(ti)代謝、生殖及神(shen)經等方面的(de)疾病(bing)。相關部門明(ming)確要求，電動車銷售行業必須(xu)做好廢(fei)舊(jiu)電池的(de)回(hui)收處理工(gong)作。而在現實當(dang)中，有(you)的(de)銷售商把廢(fei)舊(jiu)電池回(hui)收的(de)規(gui)定當(dang)成(cheng)(cheng)耳邊風，導致(zhi)部分(fen)廢(fei)舊(jiu)電池被“破爛王”收去。他(ta)們將廢(fei)舊(jiu)電池內(nei)的(de)鉛(qian)(qian)酸(suan)溶液(ye)隨(sui)地傾倒，然(ran)后(hou)將電池內(nei)的(de)鉛(qian)(qian)等取出，賣給廢(fei)品收購站。

　　專家提醒消(xiao)費者，目前全(quan)國每年產生的電動車廢舊(jiu)(jiu)電池是一個不小(xiao)(xiao)的數目。保護環(huan)境，人人有(you)責。一方面，經營(ying)者要嚴格遵守行業規(gui)定，做好廢舊(jiu)(jiu)電池的回收；另一方面，消(xiao)費者切不可貪(tan)圖蠅頭(tou)小(xiao)(xiao)利(li)，將廢舊(jiu)(jiu)電池賣給小(xiao)(xiao)商小(xiao)(xiao)販。

　　網商兵團：電動車蓄電池損壞原(yuan)因大揭秘

　　蓄電池壞損原(yuan)因(yin)很(hen)復雜(za)，大致(zhi)分為以下幾種：

　　“過充”導致蓄(xu)電(dian)池壞損(sun)

　　“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(hui)亮起，此時，充(chong)電(dian)(dian)(dian)停止或涓(juan)流充(chong)電(dian)(dian)(dian)。如果充(chong)電(dian)(dian)(dian)器電(dian)(dian)(dian)壓元件(jian)失靈(ling)，充(chong)電(dian)(dian)(dian)就不會(hui)停止，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流會(hui)不間斷(duan)地輸(shu)入電(dian)(dian)(dian)瓶，電(dian)(dian)(dian)壓就會(hui)不斷(duan)升高，電(dian)(dian)(dian)壓升高的(de)結果就會(hui)加劇電(dian)(dian)(dian)解(jie)液(ye)的(de)熱反(fan)應，輕則蓄(xu)電(dian)(dian)(dian)池外殼會(hui)變形(膨(peng)脹)，重則致使蓄(xu)電(dian)(dian)(dian)池被(bei)充(chong)爆。

　　“虧(kui)電”導致電瓶(ping)壞(huai)損(sun)

　　“虧(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)”是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量不足(zu)、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)偏(pian)低時(shi)(shi)強行過(guo)量放電(dian)(dian)(dian)(dian)(dian)(dian)產生的(de)一種破(po)壞蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)極板涂層的(de)現(xian)象。很(hen)多(duo)用(yong)戶(hu)在使(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)動車時(shi)(shi)往往是(shi)幾天(tian)充電(dian)(dian)(dian)(dian)(dian)(dian)一次，有的(de)每天(tian)行程超過(guo)新電(dian)(dian)(dian)(dian)(dian)(dian)瓶(ping)標稱里程的(de)60%以上，要知道電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量下降(jiang)會導(dao)致蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不足(zu)(欠(qian)壓(ya))，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不足(zu)就不能(neng)有效的(de)滿(man)足(zu)車載電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)基本的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)供(gong)給，當電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)下降(jiang)時(shi)(shi)，用(yong)戶(hu)還在使(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)動車，而蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)又(you)不能(neng)提供(gong)正常的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，因此就會因車載電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)負(fu)載使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)瓶(ping)欠(qian)壓(ya)出(chu)現(xian)“虧(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)”，經常性的(de)“虧(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)”就會使(shi)(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)極板鉛(qian)層逐步剝離(li)，直(zhi)至極板壞損。
