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(dian)動自(zi)行車時(shi)，不能片面追求價(jia)格低(di)，而要選擇一些(xie)質量高、市場信譽(yu)度(du)好(hao)的品牌。

　　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(de)專業知(zhi)識，也沒有(you)(you)相關的(de)專業檢測設備，對在“三包(bao)”期內出現故(gu)障的(de)電(dian)(dian)池(chi)(chi)通常只加些電(dian)(dian)解液就算維護過了(le)(le)(le)。等電(dian)(dian)池(chi)(chi)的(de)“三包(bao)”期一(yi)過，就要消(xiao)(xiao)費(fei)者(zhe)掏腰(yao)包(bao)買(mai)新(xin)(xin)電(dian)(dian)池(chi)(chi)更(geng)換了(le)(le)(le)。有(you)(you)的(de)商家(jia)對電(dian)(dian)池(chi)(chi)質量(liang)問(wen)題干(gan)脆(cui)不認賬，以(yi)消(xiao)(xiao)費(fei)者(zhe)人(ren)為損(sun)壞為由，把責任向(xiang)消(xiao)(xiao)費(fei)者(zhe)身上(shang)一(yi)推了(le)(le)(le)之。更(geng)有(you)(you)甚者(zhe)，有(you)(you)些商家(jia)表面(mian)上(shang)給消(xiao)(xiao)費(fei)者(zhe)更(geng)換新(xin)(xin)電(dian)(dian)池(chi)(chi)，卻將半舊(jiu)的(de)電(dian)(dian)池(chi)(chi)從外(wai)觀(guan)上(shang)進行技術處理，糊弄消(xiao)(xiao)費(fei)者(zhe)。暗地里，他們以(yi)消(xiao)(xiao)費(fei)者(zhe)更(geng)換新(xin)(xin)電(dian)(dian)池(chi)(chi)的(de)名義向(xiang)廠家(jia)索要新(xin)(xin)電(dian)(dian)池(chi)(chi)，坐享(xiang)其利，消(xiao)(xiao)費(fei)者(zhe)因此做了(le)(le)(le)“冤大(da)頭”。

　　專(zhuan)家(jia)提醒首(shou)先(xian)(xian)，消費者(zhe)購買電(dian)(dian)動自行車(che)要選擇有固定(ding)(ding)維修(xiu)點的(de)商家(jia)或(huo)品牌，對(dui)電(dian)(dian)動車(che)售后(hou)服務(wu)問(wen)題(ti)要與經營者(zhe)事先(xian)(xian)約定(ding)(ding)。其(qi)次(ci)，電(dian)(dian)池(chi)“三(san)(san)包”是經營者(zhe)的(de)一種(zhong)法(fa)定(ding)(ding)義務(wu)，電(dian)(dian)池(chi)在“三(san)(san)包”期內出現質量(liang)問(wen)題(ti)，要抓緊時間與商家(jia)協商解(jie)決或(huo)到相關部門投訴。再(zai)次(ci)，接受(shou)維修(xiu)、更換等處(chu)理時，一定(ding)(ding)要相關人員在保修(xiu)單上如(ru)實填寫，對(dui)更換的(de)電(dian)(dian)池(chi)要進行認真查驗。

　　維護知識少

　　據了解，一些(xie)消費者在使用電(dian)池時存在方法不(bu)當問題。一是(shi)(shi)長(chang)時間(jian)充(chong)(chong)電(dian)，認(ren)為充(chong)(chong)得(de)時間(jian)越長(chang)電(dian)量越足。二是(shi)(shi)長(chang)時間(jian)虧電(dian)，電(dian)壓接近“紅線(xian)”車(che)子跑不(bu)動了才(cai)去充(chong)(chong)電(dian)。三是(shi)(shi)在溫度過高或過低的情況下充(chong)(chong)電(dian)。四是(shi)(shi)不(bu)注意(yi)電(dian)池的定(ding)期檢(jian)查、維護和保養(yang)。五(wu)是(shi)(shi)未按說明書要求進行正確操作。

　　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)線(xian)直(zhi)徑(jing)、電(dian)壓等是否(fou)符合電(dian)動車使用說明書所規定(ding)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(yao)由鉛(qian)、硫酸(suan)以及(ji)部分(fen)金屬及(ji)塑料組成(cheng)(cheng)。廢(fei)(fei)電(dian)池(chi)酸(suan)液里含有大量的(de)鉛(qian)，隨(sui)意(yi)排(pai)放(fang)不但嚴重污染土壤和(he)水源(yuan)，還會引發人體代謝(xie)、生殖及(ji)神經等方面的(de)疾病。相關部門明(ming)確(que)要(yao)求，電(dian)動車銷(xiao)售(shou)行業必須(xu)做好廢(fei)(fei)舊(jiu)電(dian)池(chi)的(de)回(hui)(hui)收(shou)處理(li)工(gong)作。而在現(xian)實(shi)當中，有的(de)銷(xiao)售(shou)商(shang)把廢(fei)(fei)舊(jiu)電(dian)池(chi)回(hui)(hui)收(shou)的(de)規定當成(cheng)(cheng)耳邊風，導致部分(fen)廢(fei)(fei)舊(jiu)電(dian)池(chi)被“破爛王”收(shou)去。他們(men)將廢(fei)(fei)舊(jiu)電(dian)池(chi)內的(de)鉛(qian)酸(suan)溶液隨(sui)地傾倒，然后將電(dian)池(chi)內的(de)鉛(qian)等取出，賣給廢(fei)(fei)品(pin)收(shou)購站(zhan)。

　　專家(jia)提醒消(xiao)費(fei)(fei)者(zhe)，目前全國每(mei)年產生的(de)電(dian)動車廢舊(jiu)電(dian)池是一(yi)個不(bu)小的(de)數目。保護環境，人人有責。一(yi)方面(mian)，經營(ying)者(zhe)要(yao)嚴格遵守行業規定(ding)，做好廢舊(jiu)電(dian)池的(de)回收；另一(yi)方面(mian)，消(xiao)費(fei)(fei)者(zhe)切不(bu)可貪圖蠅頭小利(li)，將廢舊(jiu)電(dian)池賣給小商小販。

　　網商兵團：電動(dong)車蓄電池損壞原因大揭(jie)秘

　　蓄電池壞損原因很復雜，大致(zhi)分為以下幾種(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(lv)燈會(hui)亮起(qi)，此時，充(chong)電(dian)(dian)(dian)(dian)停(ting)止(zhi)(zhi)或涓流充(chong)電(dian)(dian)(dian)(dian)。如(ru)果(guo)充(chong)電(dian)(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)(dian)壓元件失(shi)靈，充(chong)電(dian)(dian)(dian)(dian)就不(bu)(bu)會(hui)停(ting)止(zhi)(zhi)，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流會(hui)不(bu)(bu)間(jian)斷地輸入電(dian)(dian)(dian)(dian)瓶，電(dian)(dian)(dian)(dian)壓就會(hui)不(bu)(bu)斷升高，電(dian)(dian)(dian)(dian)壓升高的(de)結果(guo)就會(hui)加劇電(dian)(dian)(dian)(dian)解液的(de)熱反應，輕則蓄(xu)電(dian)(dian)(dian)(dian)池(chi)外殼會(hui)變形(膨脹)，重則致使蓄(xu)電(dian)(dian)(dian)(dian)池(chi)被(bei)充(chong)爆。

　　“虧電”導致(zhi)電瓶壞損

　　“虧電(dian)(dian)(dian)”是電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)量不(bu)足、電(dian)(dian)(dian)壓偏低時(shi)強行過量放(fang)電(dian)(dian)(dian)產生的(de)(de)(de)(de)一種破壞(huai)蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)極(ji)板(ban)涂層(ceng)的(de)(de)(de)(de)現(xian)象。很多用戶在使用電(dian)(dian)(dian)動(dong)車時(shi)往往是幾(ji)天充電(dian)(dian)(dian)一次(ci)，有的(de)(de)(de)(de)每(mei)天行程(cheng)超過新(xin)電(dian)(dian)(dian)瓶(ping)標稱(cheng)里程(cheng)的(de)(de)(de)(de)60%以上(shang)，要知道電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量下降會(hui)導致蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)壓不(bu)足(欠壓)，電(dian)(dian)(dian)壓不(bu)足就(jiu)不(bu)能有效的(de)(de)(de)(de)滿足車載電(dian)(dian)(dian)器(qi)(qi)基(ji)本的(de)(de)(de)(de)電(dian)(dian)(dian)壓供給，當(dang)電(dian)(dian)(dian)壓下降時(shi)，用戶還在使用電(dian)(dian)(dian)動(dong)車，而蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)又不(bu)能提供正常的(de)(de)(de)(de)電(dian)(dian)(dian)壓，因此就(jiu)會(hui)因車載電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)(de)負載使電(dian)(dian)(dian)瓶(ping)欠壓出現(xian)“虧電(dian)(dian)(dian)”，經常性的(de)(de)(de)(de)“虧電(dian)(dian)(dian)”就(jiu)會(hui)使蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)極(ji)板(ban)鉛層(ceng)逐步(bu)剝離，直(zhi)至極(ji)板(ban)壞(huai)損(sun)。

　　啟動、加速、過載產生的大(da)電(dian)流放(fang)電(dian)使(shi)電(dian)瓶壞損

　　電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)啟動(dong)、加(jia)速的(de)(de)(de)(de)瞬間(jian)電(dian)(dian)(dian)(dian)(dian)流很大(da)(da)(da)，一般會達(da)到20A―50A，根據電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)(dian)機功(gong)率(lv)的(de)(de)(de)(de)大(da)(da)(da)小，正常的(de)(de)(de)(de)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流一般控(kong)制在10A以(yi)內為好。由于(yu)瞬間(jian)電(dian)(dian)(dian)(dian)(dian)流太大(da)(da)(da)，使電(dian)(dian)(dian)(dian)(dian)解反應急劇增加(jia)，極(ji)板(ban)涂(tu)層(ceng)必然會受到一定程度的(de)(de)(de)(de)影響(xiang)，久而久之極(ji)板(ban)鉛(qian)層(ceng)粉末就(jiu)會因瞬間(jian)大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流拉扯逐步脫落，電(dian)(dian)(dian)(dian)(dian)解液(ye)就(jiu)會發黑(鉛(qian)粉所致)，蓄電(dian)(dian)(dian)(dian)(dian)池(chi)就(jiu)會報廢。過載會使蓄電(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)負荷加(jia)大(da)(da)(da)，長時間(jian)的(de)(de)(de)(de)大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)，會直接影響(xiang)極(ji)板(ban)涂(tu)層(ceng)，加(jia)快極(ji)板(ban)軟化(hua)的(de)(de)(de)(de)過程。還(huan)有就(jiu)是路(lu)況不好也會使電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)頻繁的(de)(de)(de)(de)剎車(che)和啟動(dong)。這都是造成大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)因素(su)。另外值(zhi)得提出的(de)(de)(de)(de)是，電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)(dian)機功(gong)率(lv)越(yue)(yue)(yue)大(da)(da)(da)，其蓄電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)使用壽命越(yue)(yue)(yue)短(duan)，這是因為電(dian)(dian)(dian)(dian)(dian)機功(gong)率(lv)越(yue)(yue)(yue)大(da)(da)(da)，放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流也就(jiu)越(yue)(yue)(yue)大(da)(da)(da)，對電(dian)(dian)(dian)(dian)(dian)瓶的(de)(de)(de)(de)損傷也就(jiu)越(yue)(yue)(yue)大(da)(da)(da)。

　　“失水”使電瓶壞損

　　“失(shi)水(shui)(shui)”是(shi)蓄(xu)電(dian)池容量減少(shao)的(de)(de)基本原因之一。電(dian)動車采用的(de)(de)絕(jue)大(da)部(bu)分(fen)是(shi)免維(wei)護(hu)鉛酸(suan)蓄(xu)電(dian)池，很(hen)多用戶會說(shuo)(shuo)，這種電(dian)池是(shi)密封的(de)(de)，又是(shi)免維(wei)護(hu)，為(wei)什么還存在(zai)“失(shi)水(shui)(shui)”現象？其道理(li)很(hen)簡單，水(shui)(shui)是(shi)參加蓄(xu)電(dian)池電(dian)解(jie)反應的(de)(de)重(zhong)要成(cheng)(cheng)分(fen)，一旦(dan)蓄(xu)電(dian)池出現過充電(dian)、大(da)電(dian)流(liu)放電(dian)、內阻增大(da)、短路等時，容易產生(sheng)熱度(du)并形成(cheng)(cheng)水(shui)(shui)蒸(zheng)汽，水(shui)(shui)蒸(zheng)汽在(zai)密封的(de)(de)電(dian)池盒(he)內會大(da)部(bu)分(fen)被留住(zhu)，但也有極少(shao)部(bu)分(fen)會流(liu)失(shi)(因電(dian)池殼材質的(de)(de)密度(du)所決(jue)定(ding))，久而久之，電(dian)瓶就會出現“失(shi)水(shui)(shui)”狀(zhuang)態(tai)。一般來(lai)說(shuo)(shuo)，電(dian)動車電(dian)池使用6個月以上都會存在(zai)“失(shi)水(shui)(shui)”狀(zhuang)態(tai)，電(dian)機功(gong)率越(yue)大(da)，“失(shi)水(shui)(shui)”狀(zhuang)態(tai)越(yue)嚴重(zhong)。
