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，專家提醒消費者，在購買電動(dong)自行車時(shi)，不能片面追求價格低(di)，而(er)要選(xuan)擇一些質量高、市(shi)場信譽度(du)好(hao)的品牌(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(xiu)的(de)(de)專業(ye)知識，也沒(mei)有(you)相關的(de)(de)專業(ye)檢測設備，對在(zai)“三包(bao)”期內出現(xian)故障的(de)(de)電(dian)(dian)池(chi)(chi)通常只加(jia)些(xie)電(dian)(dian)解(jie)液(ye)就算(suan)維護過了。等電(dian)(dian)池(chi)(chi)的(de)(de)“三包(bao)”期一過，就要(yao)消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)掏腰包(bao)買新(xin)電(dian)(dian)池(chi)(chi)更換了。有(you)的(de)(de)商(shang)家(jia)對電(dian)(dian)池(chi)(chi)質量問題(ti)干脆不(bu)認(ren)賬，以(yi)消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)人為(wei)損壞為(wei)由，把責任向(xiang)消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)身上一推了之(zhi)。更有(you)甚者(zhe)(zhe)(zhe)，有(you)些(xie)商(shang)家(jia)表面上給消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)更換新(xin)電(dian)(dian)池(chi)(chi)，卻將半舊的(de)(de)電(dian)(dian)池(chi)(chi)從外觀上進(jin)行(xing)技術處理，糊弄消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)。暗地里(li)，他們以(yi)消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)更換新(xin)電(dian)(dian)池(chi)(chi)的(de)(de)名義向(xiang)廠(chang)家(jia)索要(yao)新(xin)電(dian)(dian)池(chi)(chi)，坐享其利，消(xiao)費(fei)(fei)者(zhe)(zhe)(zhe)因(yin)此做了“冤大頭(tou)”。

　　專(zhuan)家(jia)提醒(xing)首(shou)先，消費者(zhe)(zhe)購買電(dian)動自行車(che)(che)要(yao)(yao)選擇有(you)固定(ding)維(wei)修(xiu)點的(de)商家(jia)或品牌，對電(dian)動車(che)(che)售后(hou)服務問題要(yao)(yao)與經營者(zhe)(zhe)事先約定(ding)。其次(ci)(ci)，電(dian)池“三(san)包”是經營者(zhe)(zhe)的(de)一種(zhong)法定(ding)義務，電(dian)池在(zai)“三(san)包”期內(nei)出現(xian)質量問題，要(yao)(yao)抓緊時間與商家(jia)協商解(jie)決或到相(xiang)關部門(men)投訴。再次(ci)(ci)，接(jie)受維(wei)修(xiu)、更(geng)換等處理時，一定(ding)要(yao)(yao)相(xiang)關人(ren)員在(zai)保修(xiu)單上(shang)如(ru)實填(tian)寫，對更(geng)換的(de)電(dian)池要(yao)(yao)進(jin)行認(ren)真查驗。

　　維護知識少

　　據了(le)解，一些消費者在使用電(dian)池時存在方法不當問(wen)題。一是(shi)(shi)長時間(jian)充(chong)電(dian)，認(ren)為充(chong)得時間(jian)越長電(dian)量越足。二是(shi)(shi)長時間(jian)虧電(dian)，電(dian)壓接近“紅線”車子跑不動了(le)才去充(chong)電(dian)。三是(shi)(shi)在溫度過高(gao)或過低的情況(kuang)下(xia)充(chong)電(dian)。四是(shi)(shi)不注意(yi)電(dian)池的定期檢查、維護和保養。五是(shi)(shi)未按說明書要(yao)求(qiu)進行正確操作。

　　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)線直徑、電(dian)(dian)壓等是否符(fu)合電(dian)(dian)動車使(shi)用說明書所規定的要求。

　　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(you)鉛(qian)(qian)(qian)(qian)、硫酸(suan)以及(ji)部分(fen)金屬及(ji)塑(su)料組成。廢(fei)電(dian)(dian)(dian)(dian)(dian)池(chi)酸(suan)液里含(han)有大量的(de)(de)鉛(qian)(qian)(qian)(qian)，隨(sui)(sui)意(yi)排放不(bu)但(dan)嚴重污染(ran)土壤(rang)和水源，還(huan)會引(yin)發人體代(dai)謝、生殖(zhi)及(ji)神經等方面的(de)(de)疾(ji)病(bing)。相(xiang)關部門明確(que)要求，電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)銷售行(xing)業必須做好(hao)廢(fei)舊電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)回收處理工作。而(er)在現實當中，有的(de)(de)銷售商把廢(fei)舊電(dian)(dian)(dian)(dian)(dian)池(chi)回收的(de)(de)規(gui)定當成耳邊風，導致部分(fen)廢(fei)舊電(dian)(dian)(dian)(dian)(dian)池(chi)被“破爛王(wang)”收去。他們將廢(fei)舊電(dian)(dian)(dian)(dian)(dian)池(chi)內(nei)的(de)(de)鉛(qian)(qian)(qian)(qian)酸(suan)溶液隨(sui)(sui)地傾倒，然后將電(dian)(dian)(dian)(dian)(dian)池(chi)內(nei)的(de)(de)鉛(qian)(qian)(qian)(qian)等取出，賣給(gei)廢(fei)品收購站。

　　專家提醒消費者，目前全(quan)國(guo)每(mei)年(nian)產生的(de)電(dian)動車廢(fei)(fei)舊電(dian)池(chi)是一個不小的(de)數目。保護環境，人人有責。一方面(mian)，經營者要嚴格遵守行業規定，做好(hao)廢(fei)(fei)舊電(dian)池(chi)的(de)回(hui)收；另一方面(mian)，消費者切不可貪圖蠅頭小利，將廢(fei)(fei)舊電(dian)池(chi)賣給小商小販。

　　網商兵團：電動車蓄電池損壞原因大揭秘

　　蓄電池(chi)壞損原因很(hen)復雜，大(da)致分為以下幾(ji)種(zhong)：

　　“過充”導致(zhi)蓄電(dian)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(hui)亮起，此時，充(chong)電(dian)(dian)(dian)停(ting)止或(huo)涓流充(chong)電(dian)(dian)(dian)。如果(guo)充(chong)電(dian)(dian)(dian)器電(dian)(dian)(dian)壓元件失(shi)靈，充(chong)電(dian)(dian)(dian)就(jiu)不(bu)(bu)會(hui)停(ting)止，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流會(hui)不(bu)(bu)間斷地輸入電(dian)(dian)(dian)瓶，電(dian)(dian)(dian)壓就(jiu)會(hui)不(bu)(bu)斷升(sheng)高，電(dian)(dian)(dian)壓升(sheng)高的結果(guo)就(jiu)會(hui)加(jia)劇電(dian)(dian)(dian)解液的熱(re)反應，輕則蓄(xu)電(dian)(dian)(dian)池外殼會(hui)變形(膨脹)，重則致(zhi)使蓄(xu)電(dian)(dian)(dian)池被充(chong)爆。

　　“虧電”導致電瓶壞損(sun)
