廠家(jia)拼價格

　　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(jia)提醒消費(fei)者，在購買電動(dong)自行(xing)車時，不能片面(mian)追(zhui)求價格(ge)低，而(er)要選擇一(yi)些質量(liang)高(gao)、市場信譽度好的品(pin)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(wei)修的(de)專業知(zhi)識，也沒有(you)相(xiang)關的(de)專業檢測設備，對(dui)在“三(san)包”期(qi)內出現(xian)故障的(de)電(dian)(dian)池(chi)通(tong)常(chang)只加些電(dian)(dian)解液就算(suan)維(wei)護過了(le)。等電(dian)(dian)池(chi)的(de)“三(san)包”期(qi)一(yi)過，就要消(xiao)(xiao)費(fei)(fei)者(zhe)掏(tao)腰包買新(xin)電(dian)(dian)池(chi)更(geng)(geng)換(huan)了(le)。有(you)的(de)商家對(dui)電(dian)(dian)池(chi)質(zhi)量問題干(gan)脆不認賬，以(yi)消(xiao)(xiao)費(fei)(fei)者(zhe)人為(wei)損壞為(wei)由，把責任向(xiang)消(xiao)(xiao)費(fei)(fei)者(zhe)身上(shang)(shang)一(yi)推了(le)之。更(geng)(geng)有(you)甚者(zhe)，有(you)些商家表面上(shang)(shang)給消(xiao)(xiao)費(fei)(fei)者(zhe)更(geng)(geng)換(huan)新(xin)電(dian)(dian)池(chi)，卻將半舊的(de)電(dian)(dian)池(chi)從外觀上(shang)(shang)進(jin)行技術處理(li)，糊弄消(xiao)(xiao)費(fei)(fei)者(zhe)。暗(an)地(di)里，他們(men)以(yi)消(xiao)(xiao)費(fei)(fei)者(zhe)更(geng)(geng)換(huan)新(xin)電(dian)(dian)池(chi)的(de)名義向(xiang)廠家索(suo)要新(xin)電(dian)(dian)池(chi)，坐享其(qi)利(li)，消(xiao)(xiao)費(fei)(fei)者(zhe)因(yin)此做了(le)“冤大頭”。

　　專家提醒首先(xian)，消(xiao)費者(zhe)購買(mai)電(dian)(dian)動(dong)自行(xing)車要選(xuan)擇有固定維修點的(de)商(shang)家或品牌，對(dui)(dui)電(dian)(dian)動(dong)車售(shou)后服務問題要與經(jing)營者(zhe)事先(xian)約定。其次(ci)，電(dian)(dian)池(chi)(chi)“三包(bao)”是(shi)經(jing)營者(zhe)的(de)一種法定義(yi)務，電(dian)(dian)池(chi)(chi)在“三包(bao)”期內出現質量問題，要抓緊(jin)時間與商(shang)家協商(shang)解(jie)決或到相(xiang)關部(bu)門投訴。再次(ci)，接受(shou)維修、更換等(deng)處理時，一定要相(xiang)關人員(yuan)在保(bao)修單上如實填寫，對(dui)(dui)更換的(de)電(dian)(dian)池(chi)(chi)要進行(xing)認真查(cha)驗。

　　維護知識少

　　據(ju)了解，一(yi)些消費者在使用電(dian)(dian)池時(shi)存在方法不(bu)當問(wen)題。一(yi)是(shi)長時(shi)間充電(dian)(dian)，認為充得(de)時(shi)間越(yue)長電(dian)(dian)量越(yue)足。二是(shi)長時(shi)間虧電(dian)(dian)，電(dian)(dian)壓接近“紅線(xian)”車子(zi)跑不(bu)動了才去充電(dian)(dian)。三是(shi)在溫度過(guo)高(gao)或過(guo)低的(de)情(qing)況下充電(dian)(dian)。四是(shi)不(bu)注意電(dian)(dian)池的(de)定期檢查、維護和(he)保養。五是(shi)未按說明書(shu)要求進(jin)行正(zheng)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)線直(zhi)徑、電(dian)壓等是否符合電(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、硫酸(suan)以及部分(fen)金屬及塑料組成。廢(fei)(fei)(fei)電池酸(suan)液里(li)含有(you)大(da)量的(de)(de)鉛，隨(sui)意排(pai)放(fang)不但嚴重污染土(tu)壤和水源，還會引發人體代謝、生殖及神經(jing)等方面(mian)的(de)(de)疾病。相(xiang)關部門(men)明確(que)要(yao)求，電動車銷售行業必須(xu)做(zuo)好廢(fei)(fei)(fei)舊(jiu)電池的(de)(de)回收(shou)處理工作。而在現(xian)實當(dang)中，有(you)的(de)(de)銷售商把廢(fei)(fei)(fei)舊(jiu)電池回收(shou)的(de)(de)規(gui)定當(dang)成耳邊風，導(dao)致部分(fen)廢(fei)(fei)(fei)舊(jiu)電池被(bei)“破(po)爛王”收(shou)去(qu)。他們(men)將廢(fei)(fei)(fei)舊(jiu)電池內的(de)(de)鉛酸(suan)溶液隨(sui)地傾倒，然后將電池內的(de)(de)鉛等取出，賣給(gei)廢(fei)(fei)(fei)品收(shou)購站。

　　專家提醒消費者，目前全國每年產生的電(dian)(dian)動(dong)車(che)廢舊(jiu)電(dian)(dian)池(chi)(chi)是一個不小(xiao)的數目。保護環境，人人有責。一方面，經營者要(yao)嚴格遵守行業規定，做好(hao)廢舊(jiu)電(dian)(dian)池(chi)(chi)的回收；另一方面，消費者切(qie)不可貪圖蠅(ying)頭小(xiao)利，將廢舊(jiu)電(dian)(dian)池(chi)(chi)賣給小(xiao)商小(xiao)販。

　　網商兵團：電(dian)(dian)動車(che)蓄(xu)電(dian)(dian)池(chi)損壞原(yuan)因大揭秘

　　蓄電池壞損原因很復雜(za)，大致分為以下幾(ji)種：

　　“過充”導致蓄電池壞損(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(lv)燈會(hui)亮起，此時，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)停止(zhi)或涓流(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。如(ru)果充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)元件(jian)失靈，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)就不會(hui)停止(zhi)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)會(hui)不間斷(duan)地輸入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)瓶，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)就會(hui)不斷(duan)升(sheng)高，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)升(sheng)高的結果就會(hui)加(jia)劇電(dian)(dian)(dian)(dian)(dian)(dian)解液的熱反應(ying)，輕則蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池外殼會(hui)變(bian)形(膨脹)，重則致(zhi)使(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池被充(chong)爆。

　　“虧電”導致電瓶(ping)壞損

　　“虧(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)”是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量不(bu)足、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)偏低時(shi)(shi)強行過量放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)產生(sheng)的(de)一(yi)種破(po)壞(huai)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池極(ji)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)(dian)動車時(shi)(shi)往(wang)(wang)往(wang)(wang)是幾天(tian)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)一(yi)次，有的(de)每天(tian)行程(cheng)超過新電(dian)(dian)(dian)(dian)(dian)(dian)(dian)瓶(ping)標稱里程(cheng)的(de)60%以上，要知道電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池容量下(xia)降(jiang)會(hui)(hui)導(dao)致蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)足(欠壓(ya))，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)足就(jiu)不(bu)能(neng)有效的(de)滿足車載(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器基本的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)供給，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)下(xia)降(jiang)時(shi)(shi)，用(yong)戶(hu)還(huan)在使(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車，而蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池又不(bu)能(neng)提供正常的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，因此就(jiu)會(hui)(hui)因車載(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)負載(zai)(zai)使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)瓶(ping)欠壓(ya)出現(xian)“虧(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)”，經常性(xing)的(de)“虧(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)”就(jiu)會(hui)(hui)使(shi)(shi)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池極(ji)板鉛(qian)層逐步剝(bo)離，直至(zhi)極(ji)板壞(huai)損。

　　啟動、加(jia)速、過載產生的大電(dian)流放(fang)電(dian)使電(dian)瓶(ping)壞損

　　電(dian)(dian)(dian)動(dong)(dong)車(che)(che)啟動(dong)(dong)、加(jia)速的(de)(de)瞬(shun)間(jian)(jian)電(dian)(dian)(dian)流(liu)(liu)很大，一般會(hui)(hui)達到20A―50A，根據電(dian)(dian)(dian)動(dong)(dong)車(che)(che)電(dian)(dian)(dian)機(ji)(ji)功率(lv)的(de)(de)大小，正(zheng)常的(de)(de)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)一般控制在10A以內為好。由于瞬(shun)間(jian)(jian)電(dian)(dian)(dian)流(liu)(liu)太大，使(shi)電(dian)(dian)(dian)解(jie)反(fan)應急(ji)劇增加(jia)，極板(ban)涂層必然會(hui)(hui)受到一定(ding)程度(du)的(de)(de)影響(xiang)，久而久之極板(ban)鉛層粉末就會(hui)(hui)因瞬(shun)間(jian)(jian)大電(dian)(dian)(dian)流(liu)(liu)拉扯逐步脫落，電(dian)(dian)(dian)解(jie)液就會(hui)(hui)發(fa)黑(hei)(鉛粉所致)，蓄(xu)電(dian)(dian)(dian)池(chi)就會(hui)(hui)報廢。過(guo)載(zai)會(hui)(hui)使(shi)蓄(xu)電(dian)(dian)(dian)池(chi)放(fang)(fang)電(dian)(dian)(dian)負荷加(jia)大，長時間(jian)(jian)的(de)(de)大電(dian)(dian)(dian)流(liu)(liu)放(fang)(fang)電(dian)(dian)(dian)，會(hui)(hui)直(zhi)接影響(xiang)極板(ban)涂層，加(jia)快極板(ban)軟化的(de)(de)過(guo)程。還有(you)就是路(lu)況不好也(ye)(ye)會(hui)(hui)使(shi)電(dian)(dian)(dian)動(dong)(dong)車(che)(che)頻繁的(de)(de)剎車(che)(che)和啟動(dong)(dong)。這都是造成大電(dian)(dian)(dian)流(liu)(liu)放(fang)(fang)電(dian)(dian)(dian)的(de)(de)因素(su)。另外值得提(ti)出(chu)的(de)(de)是，電(dian)(dian)(dian)動(dong)(dong)車(che)(che)電(dian)(dian)(dian)機(ji)(ji)功率(lv)越(yue)(yue)大，其蓄(xu)電(dian)(dian)(dian)池(chi)的(de)(de)使(shi)用壽命越(yue)(yue)短(duan)，這是因為電(dian)(dian)(dian)機(ji)(ji)功率(lv)越(yue)(yue)大，放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)也(ye)(ye)就越(yue)(yue)大，對電(dian)(dian)(dian)瓶的(de)(de)損(sun)傷也(ye)(ye)就越(yue)(yue)大。

　　“失(shi)水”使電瓶壞損

　　“失(shi)水(shui)”是(shi)(shi)蓄電(dian)(dian)(dian)(dian)(dian)池容量減少的基本原因(yin)之(zhi)一。電(dian)(dian)(dian)(dian)(dian)動車采用的絕大(da)部(bu)分(fen)是(shi)(shi)免(mian)維護(hu)鉛酸蓄電(dian)(dian)(dian)(dian)(dian)池，很多用戶會(hui)說(shuo)，這種(zhong)電(dian)(dian)(dian)(dian)(dian)池是(shi)(shi)密封(feng)的，又(you)是(shi)(shi)免(mian)維護(hu)，為(wei)什(shen)么還(huan)存在(zai)(zai)“失(shi)水(shui)”現(xian)象？其(qi)道理很簡(jian)單，水(shui)是(shi)(shi)參加蓄電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)解反應的重要成分(fen)，一旦蓄電(dian)(dian)(dian)(dian)(dian)池出(chu)現(xian)過充電(dian)(dian)(dian)(dian)(dian)、大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)(dian)、內阻(zu)增(zeng)大(da)、短路等時，容易產(chan)生熱度(du)并形成水(shui)蒸(zheng)汽(qi)(qi)，水(shui)蒸(zheng)汽(qi)(qi)在(zai)(zai)密封(feng)的電(dian)(dian)(dian)(dian)(dian)池盒(he)內會(hui)大(da)部(bu)分(fen)被留住，但(dan)也(ye)有極(ji)少部(bu)分(fen)會(hui)流(liu)失(shi)(因(yin)電(dian)(dian)(dian)(dian)(dian)池殼材質的密度(du)所決定(ding))，久而久之(zhi)，電(dian)(dian)(dian)(dian)(dian)瓶就會(hui)出(chu)現(xian)“失(shi)水(shui)”狀態。一般來(lai)說(shuo)，電(dian)(dian)(dian)(dian)(dian)動車電(dian)(dian)(dian)(dian)(dian)池使(shi)用6個月以上都會(hui)存在(zai)(zai)“失(shi)水(shui)”狀態，電(dian)(dian)(dian)(dian)(dian)機功率越大(da)，“失(shi)水(shui)”狀態越嚴重。
