一、蓄電池的安裝

　　蓄(xu)(xu)電池(chi)一(yi)(yi)般采用串聯方式使用，即(ji)一(yi)(yi)只(zhi)(zhi)蓄(xu)(xu)電池(chi)的(de)(de)正(zheng)極與另一(yi)(yi)只(zhi)(zhi)蓄(xu)(xu)電池(chi)的(de)(de)負極相(xiang)連，將所(suo)有蓄(xu)(xu)電池(chi)連在一(yi)(yi)起(qi)，最后余下正(zheng)負接(jie)線端子與電動(dong)車(che)對(dui)應接(jie)線相(xiang)連，電動(dong)車(che)的(de)(de)電機、控制器、儀(yi)表等是(shi)蓄(xu)(xu)電池(chi)的(de)(de)用電負載(zai)。

　　電(dian)(dian)(dian)(dian)動車(che)一(yi)般(ban)都(dou)有電(dian)(dian)(dian)(dian)池(chi)盒，從安(an)裝(zhuang)位置分有斜杠式(shi)，后插式(shi)和(he)底(di)盤式(shi)安(an)裝(zhuang)，其結構(gou)形狀可謂五花(hua)八門。每家電(dian)(dian)(dian)(dian)動車(che)廠都(dou)各(ge)有特色(se)。如圖(tu)電(dian)(dian)(dian)(dian)池(chi)盒一(yi)般(ban)用(yong)工程塑料制成(cheng)，其強度較好(hao)(hao)，重量較輕，安(an)裝(zhuang)方便。電(dian)(dian)(dian)(dian)池(chi)盒一(yi)般(ban)由底(di)槽、上蓋、蓄電(dian)(dian)(dian)(dian)池(chi)接觸點及(ji)充電(dian)(dian)(dian)(dian)插座、電(dian)(dian)(dian)(dian)車(che)鎖等組成(cheng)。底(di)槽與上蓋扣緊(jin)，并用(yong)自攻螺絲或(huo)螺栓緊(jin)固。電(dian)(dian)(dian)(dian)池(chi)盒是按蓄電(dian)(dian)(dian)(dian)池(chi)型號(hao)規格進行(xing)設計的，在(zai)整車(che)設計時應考慮其良(liang)好(hao)(hao)的散熱性能(neng)。

    二、蓄電(dian)池(chi)的充(chong)電(dian)

　　“蓄電(dian)池(chi)(chi)不是用(yong)壞的而是充(chong)壞的”，這一說法(fa)絕(jue)非危言聳聽，蓄電(dian)池(chi)(chi)充(chong)電(dian)性(xing)能好(hao)壞對蓄電(dian)池(chi)(chi)的使用(yong)壽(shou)命和使用(yong)性(xing)能起著舉(ju)足(zu)輕(qing)重的作用(yong)，必(bi)須重視。

 　　1、蓄電池對充(chong)電工藝的(de)要求

　　認識蓄電池對充電工藝的基本要求，是分析各種電池充電器技術的基礎。蓄電池對蓄電池充電器充(chong)電的(de)基本(ben)要求(qiu)是：充(chong)電電流應小(xiao)于或(huo)等于蓄電池可接收充(chong)電電流。否(fou)則(ze)，過(guo)剩的(de)電流會使(shi)電解水(shui)液(ye)過(guo)快地消耗掉(diao)，產生以下危害(hai)：加大(da)蓄電池的(de)失(shi)水(shui)率(lv)，增加維護(hu)工作量，對于免維護(hu)電池，會造成蓄電池的(de)早期失(shi)效；產生酸霧，造成環(huan)境污染(ran)，危害(hai)工人身體健康(kang)；使(shi)充(chong)電效率(lv)降低(di)，造成能源的(de)嚴重浪費(fei)。

　　充(chong)電(dian)(dian)(dian)過程，是(shi)放電(dian)(dian)(dian)電(dian)(dian)(dian)化(hua)學反應(ying)(ying)的(de)(de)逆反應(ying)(ying)過程，如果充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)化(hua)學反應(ying)(ying)過程在(zai)理想的(de)(de)狀態下(xia)進行，這個過程應(ying)(ying)該是(shi)互(hu)為逆反應(ying)(ying)，即充(chong)入(ru)的(de)(de)電(dian)(dian)(dian)量與放出的(de)(de)電(dian)(dian)(dian)量應(ying)(ying)基本相等。但在(zai)嚴重(zhong)析氣的(de)(de)狀態下(xia)，有效充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)化(hua)學反應(ying)(ying)過程消耗的(de)(de)電(dian)(dian)(dian)能達不(bu)到(dao)總電(dian)(dian)(dian)量的(de)(de)40%，即浪費電(dian)(dian)(dian)能60%以上。

　　氣體的產生聚集在蓄電(dian)(dian)池多(duo)孔電(dian)(dian)極(ji)(ji)內部，減(jian)少(shao)了(le)電(dian)(dian)解(jie)質與多(duo)孔電(dian)(dian)極(ji)(ji)的接(jie)觸面積，即充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)化學(xue)反應界面大幅度減(jian)小(xiao)，使充(chong)(chong)(chong)電(dian)(dian)化學(xue)反應速度降(jiang)低(di)，充(chong)(chong)(chong)電(dian)(dian)十分困難(nan)，充(chong)(chong)(chong)電(dian)(dian)時間延長。

　　嚴重(zhong)的析氣會損害蓄電池：

      ①大量(liang)氣體的產生(sheng)對極板活性(xing)物有沖(chong)刷作用，使活性(xing)物質容易松軟和脫落。

      ②在較高(gao)的(de)(de)(de)極化(hua)(hua)電(dian)壓下，正極板的(de)(de)(de)板柵會(hui)產生(sheng)(sheng)嚴重(zhong)腐(fu)蝕，生(sheng)(sheng)成Pb02，這種腐(fu)蝕物與電(dian)化(hua)(hua)學生(sheng)(sheng)存的(de)(de)(de)Pb02是(shi)完全不同的(de)(de)(de)，是(shi)一種不可逆的(de)(de)(de)氧化(hua)(hua)物，導電(dian)較差(cha)，并使板柵變形，脆裂，失去骨架(jia)和(he)導電(dian)作用。因此在充電(dian)時應盡可能防止過充電(dian)。

 　　長期充(chong)電(dian)不足，未反應的(de)活性物(wu)質會產(chan)生(sheng)不可(ke)逆(ni)(ni)的(de)高陽性的(de)大顆粒(li)PbS04晶(jing)粒(li)(即不可(ke)逆(ni)(ni)硫酸鹽化)使蓄(xu)電(dian)池容量下降，內阻加(jia)大，充(chong)電(dian)難(nan)度加(jia)大，造(zao)成蓄(xu)電(dian)池早期損壞。因此，蓄(xu)電(dian)池要(yao)盡量保證充(chong)足電(dian)，防(fang)止不可(ke)逆(ni)(ni)硫酸鹽化。

 　　2、充電頻次(ci)的選擇

　　蓄(xu)電(dian)池充電(dian)深度對循(xun)(xun)環(huan)壽(shou)命影(ying)響很(hen)大，基本(ben)呈指(zhi)數變化(hua)。這(zhe)是由于(yu)正極活性物(wu)為Pb02，其結合牢度不高，放(fang)電(dian)時轉化(hua)成(cheng)PbS04充電(dian)時又轉化(hua)成(cheng)P，而(er)P的(de)體(ti)積遠比P體(ti)積大(其體(ti)積之(zhi)比約(yue)為2:1)。因此，對正極板而(er)言，活性物(wu)將(jiang)會膨脹(zhang)收縮(suo)反復進行，使(shi)其粒子之(zhi)間的(de)連接逐漸脫落(luo)，使(shi)蓄(xu)電(dian)池活性物(wu)失(shi)去放(fang)電(dian)特性成(cheng)為“陽極泥”，使(shi)蓄(xu)電(dian)池性能(neng)下降(jiang)，直至(zhi)壽(shou)命終(zhong)止。放(fang)電(dian)深度越深，膨脹(zhang)收縮(suo)量(liang)越大，對活性物(wu)結合力破壞越大，壽(shou)命越短；反之(zhi)則循(xun)(xun)環(huan)壽(shou)命越長。

　　從理(li)論上講蓄(xu)電池(chi)使用(yong)時(shi)(shi)應(ying)盡量避免深(shen)放(fang)電，應(ying)做到淺放(fang)勤充(chong)(chong)(chong)，前提(ti)是(shi)(shi)有特別匹配的鉛酸電池(chi)充(chong)(chong)(chong)電器(qi)與之匹配。但是(shi)(shi)實際(ji)使用(yong)中，由于蓄(xu)電池(chi)充(chong)(chong)(chong)電受充(chong)(chong)(chong)電器(qi)性能和蓄(xu)電池(chi)本(ben)身的離散及(ji)充(chong)(chong)(chong)電習慣及(ji)充(chong)(chong)(chong)電速度影響，充(chong)(chong)(chong)電器(qi)的電壓均比較(jiao)高，或多或少都存在過(guo)(guo)充(chong)(chong)(chong)電。特別是(shi)(shi)充(chong)(chong)(chong)電多數在夜間(jian)進行，時(shi)(shi)間(jian)一般在6-10小(xiao)(xiao)時(shi)(shi)，平均8小(xiao)(xiao)時(shi)(shi)左(zuo)右，若是(shi)(shi)淺放(fang)電，其(qi)充(chong)(chong)(chong)電很快就會(hui)(hui)到達末期，這時(shi)(shi)充(chong)(chong)(chong)電效率變低，會(hui)(hui)產生過(guo)(guo)充(chong)(chong)(chong)電。過(guo)(guo)充(chong)(chong)(chong)電時(shi)(shi)間(jian)比較(jiao)長，加上頻繁充(chong)(chong)(chong)電，就會(hui)(hui)使蓄(xu)電池(chi)壽(shou)命因充(chong)(chong)(chong)電受到較(jiao)大影響。

　　最理想的充電(dian)(dian)(dian)要求(qiu)根據實際情況而定，要參(can)考平時運行(xing)頻率、里程情況、蓄電(dian)(dian)(dian)池廠提(ti)供的說明，以及(ji)配套的充電(dian)(dian)(dian)器(qi)性能等參(can)數(shu)制(zhi)定充電(dian)(dian)(dian)頻次。按絕大多數(shu)用戶的情況，蓄電(dian)(dian)(dian)池以放電(dian)(dian)(dian)深度(du)為50%-70%時充一次電(dian)(dian)(dian)最佳，這樣可使蓄電(dian)(dian)(dian)池壽命達到最佳效果。實際使用時可折算成(cheng)騎行(xing)里程，在(zai)需要時充一次。

　　3、溫度對(dui)充電的影響

　　蓄(xu)電(dian)池(chi)在(zai)(zai)高溫(wen)季節運行(xing)，主要(yao)存在(zai)(zai)過充(chong)電(dian)的(de)(de)問題(ti)。蓄(xu)電(dian)池(chi)溫(wen)度(du)(du)增(zeng)高時(shi)(shi)，各活性(xing)物(wu)質的(de)(de)活度(du)(du)增(zeng)加，正極析氧電(dian)位(wei)一下(xia)降(jiang)，負極析氧電(dian)位(wei)也下(xia)降(jiang)(負值下(xia)降(jiang))，因此，充(chong)電(dian)時(shi)(shi)充(chong)電(dian)反(fan)應(ying)速度(du)(du)快，充(chong)電(dian)電(dian)流大，充(chong)電(dian)時(shi)(shi)需要(yao)的(de)(de)充(chong)電(dian)電(dian)壓(ya)較(jiao)低(di)。為(wei)防止過高的(de)(de)充(chong)電(dian)電(dian)壓(ya)，應(ying)盡量(liang)降(jiang)低(di)蓄(xu)電(dian)池(chi)溫(wen)度(du)(du)，保證良好散熱(re)，防止在(zai)(zai)烈日(ri)暴曬(shai)后即充(chong)電(dian)，并應(ying)遠(yuan)離熱(re)源。

　　蓄電(dian)(dian)(dian)(dian)池在低(di)(di)溫(wen)(wen)情況下，各活性物質活度降低(di)(di)，其電(dian)(dian)(dian)(dian)極(ji)(ji)上的P溶解變得困難，充(chong)電(dian)(dian)(dian)(dian)時(shi)消耗P后很難得到補充(chong)，所充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)大幅度下降，正極(ji)(ji)板在-20℃時(shi)充(chong)電(dian)(dian)(dian)(dian)接(jie)受(shou)(shou)電(dian)(dian)(dian)(dian)流(liu)僅為常溫(wen)(wen)的70%，而負極(ji)(ji)充(chong)電(dian)(dian)(dian)(dian)受(shou)(shou)膨脹劑的影響，低(di)(di)溫(wen)(wen)充(chong)電(dian)(dian)(dian)(dian)接(jie)受(shou)(shou)能(neng)力更低(di)(di)，-20℃的充(chong)電(dian)(dian)(dian)(dian)接(jie)受(shou)(shou)電(dian)(dian)(dian)(dian)流(liu)僅為常溫(wen)(wen)下的40%。因(yin)此(ci)，低(di)(di)溫(wen)(wen)條件(jian)下充(chong)電(dian)(dian)(dian)(dian)主(zhu)要(yao)存在充(chong)電(dian)(dian)(dian)(dian)接(jie)受(shou)(shou)能(neng)力差(cha)、充(chong)電(dian)(dian)(dian)(dian)不(bu)足的問題，要(yao)求提(ti)高充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓和延長充(chong)電(dian)(dian)(dian)(dian)時(shi)間。改善(shan)低(di)(di)溫(wen)(wen)性能(neng)主(zhu)要(yao)應從負極(ji)(ji)著手(shou)。低(di)(di)溫(wen)(wen)使(shi)用(yong)時(shi)應采取(qu)保溫(wen)(wen)防凍(dong)措施，特別是充(chong)電(dian)(dian)(dian)(dian)時(shi)應放在溫(wen)(wen)暖的環境中，有利(li)于保證充(chong)足電(dian)(dian)(dian)(dian)，防止不(bu)可逆硫酸的產生，延長蓄電(dian)(dian)(dian)(dian)池的使(shi)用(yong)壽(shou)命。

　　蓄電(dian)池(chi)的(de)存儲和使用期(qi)間，可定期(qi)進行活化(hua)充(chong)電(dian)，即所(suo)謂的(de)均衡充(chong)電(dian)，這對(dui)防止蓄電(dian)池(chi)不可逆(ni)硫酸鹽(yan)化(hua)非(fei)常有利，對(dui)蓄電(dian)池(chi)使用壽命很(hen)有好處，值得提倡。

　　三、蓄(xu)電(dian)池的使用注(zhu)意(yi)事項(xiang)

　　1、防止過放電

　　蓄電池放電到終止電壓(ya)后，繼續放電稱(cheng)為過放電。過放電會(hui)嚴(yan)重損害(hai)蓄電池，對(dui)蓄電池的電氣性(xing)能及循環(huan)壽命極為不(bu)利(li)。

　　蓄電(dian)池放(fang)電(dian)到終止電(dian)壓時(shi)內阻較大(da)(da)，電(dian)解液(ye)濃度非常稀(xi)薄，特(te)(te)別是極板孔內及表(biao)面幾乎處(chu)于中性，過(guo)放(fang)電(dian)時(shi)內阻有發熱傾(qing)向，體(ti)積膨脹，放(fang)電(dian)電(dian)流較大(da)(da)時(shi)，明顯(xian)發熱(甚至出現發熱變形)，這時(shi)硫酸(suan)鉛濃度特(te)(te)別大(da)(da)，生(sheng)存晶枝短(duan)路的可能性增大(da)(da)，況且(qie)此時(shi)硫酸(suan)鉛會結晶成較大(da)(da)顆粒，即形成不可逆硫酸(suan)鹽(yan)化，將(jiang)進(jin)一(yi)步增大(da)(da)內阻，充(chong)電(dian)恢復能力(li)很差，甚至無法(fa)修(xiu)復。

　　蓄電(dian)(dian)(dian)(dian)(dian)池使用(yong)時(shi)(shi)應防止(zhi)過(guo)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，采取“欠壓保(bao)護”是(shi)很有效的(de)措施(shi)。另外，由于(yu)電(dian)(dian)(dian)(dian)(dian)動車(che)(che)“欠壓保(bao)護”是(shi)由控制器(qi)控制的(de)，但控制器(qi)以外的(de)其他(ta)一些設備(bei)如電(dian)(dian)(dian)(dian)(dian)壓表(biao)、指示燈等耗(hao)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)由蓄電(dian)(dian)(dian)(dian)(dian)池直接供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)，其電(dian)(dian)(dian)(dian)(dian)源的(de)供(gong)給一般不受(shou)控制器(qi)控制，電(dian)(dian)(dian)(dian)(dian)動車(che)(che)鎖(suo)(開(kai)關)一旦合上就(jiu)開(kai)始(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)。雖然電(dian)(dian)(dian)(dian)(dian)流小，但若長(chang)時(shi)(shi)間放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(1-2周)就(jiu)會出現(xian)過(guo)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。因此，不得長(chang)時(shi)(shi)間開(kai)鎖(suo)，不用(yong)時(shi)(shi)應立即關掉。

　　2、防止過充電

　　前(qian)面已經對過(guo)充(chong)(chong)電(dian)(dian)進(jin)行(xing)了(le)闡述，過(guo)充(chong)(chong)電(dian)(dian)會(hui)加(jia)大蓄(xu)電(dian)(dian)池(chi)的(de)水(shui)損(sun)失，會(hui)加(jia)速板柵腐蝕(shi)，活性(xing)物(wu)質軟(ruan)化，會(hui)增加(jia)蓄(xu)電(dian)(dian)池(chi)變(bian)形的(de)幾率(lv)。應盡量(liang)避免(mian)過(guo)充(chong)(chong)電(dian)(dian)的(de)發生；選(xuan)擇(ze)充(chong)(chong)電(dian)(dian)器參數要(yao)與蓄(xu)電(dian)(dian)池(chi)良(liang)好匹配，要(yao)充(chong)(chong)分(fen)了(le)解蓄(xu)電(dian)(dian)池(chi)在高溫季節的(de)運行(xing)狀況，以及整(zheng)個使用壽命期(qi)間的(de)變(bian)化情況。使用時(shi)不要(yao)將蓄(xu)電(dian)(dian)池(chi)置于過(guo)熱環境中，特(te)別是充(chong)(chong)電(dian)(dian)時(shi)應遠(yuan)離熱源。蓄(xu)電(dian)(dian)池(chi)受熱后(hou)要(yao)采取降溫措施，待(dai)蓄(xu)電(dian)(dian)池(chi)溫度恢復(fu)正常時(shi)方可進(jin)行(xing)充(chong)(chong)電(dian)(dian)。蓄(xu)電(dian)(dian)池(chi)的(de)安裝位(wei)置應盡可能保證(zheng)良(liang)好散熱，發現過(guo)熱時(shi)應停止充(chong)(chong)電(dian)(dian)，應對充(chong)(chong)電(dian)(dian)器和蓄(xu)電(dian)(dian)池(chi)進(jin)行(xing)檢查。蓄(xu)電(dian)(dian)池(chi)放(fang)電(dian)(dian)深度較淺時(shi)或環境溫度偏高時(shi)應縮短充(chong)(chong)電(dian)(dian)時(shi)間。

　　3、防止短路

　　蓄(xu)電(dian)(dian)(dian)(dian)池(chi)在(zai)短(duan)(duan)路(lu)狀態時(shi)(shi)，其短(duan)(duan)路(lu)電(dian)(dian)(dian)(dian)流(liu)可(ke)達數百安培。短(duan)(duan)路(lu)接觸越牢，短(duan)(duan)路(lu)電(dian)(dian)(dian)(dian)流(liu)越大(da)(da)，因此所有(you)連接部分都會(hui)產(chan)(chan)生(sheng)(sheng)(sheng)大(da)(da)量(liang)熱量(liang)，在(zai)薄(bo)弱(ruo)環節發熱量(liang)更大(da)(da)，會(hui)將連接處(chu)熔(rong)斷(duan)，產(chan)(chan)生(sheng)(sheng)(sheng)短(duan)(duan)路(lu)現象。蓄(xu)電(dian)(dian)(dian)(dian)池(chi)局部可(ke)能產(chan)(chan)生(sheng)(sheng)(sheng)可(ke)爆氣體(或(huo)充電(dian)(dian)(dian)(dian)時(shi)(shi)集存(cun)的可(ke)爆氣體)，在(zai)連接處(chu)熔(rong)斷(duan)時(shi)(shi)產(chan)(chan)生(sheng)(sheng)(sheng)火花，會(hui)引起蓄(xu)電(dian)(dian)(dian)(dian)池(chi)爆炸；若蓄(xu)電(dian)(dian)(dian)(dian)池(chi)短(duan)(duan)路(lu)時(shi)(shi)間較(jiao)短(duan)(duan)或(huo)電(dian)(dian)(dian)(dian)流(liu)不是特別大(da)(da)時(shi)(shi)，可(ke)能不會(hui)引起連接處(chu)熔(rong)斷(duan)現象，但短(duan)(duan)路(lu)仍(reng)會(hui)有(you)過熱現象，會(hui)損(sun)壞(huai)連接條周圍的粘(zhan)結劑，使其留下漏液等隱患。因此，蓄(xu)電(dian)(dian)(dian)(dian)池(chi)絕對不能有(you)短(duan)(duan)路(lu)產(chan)(chan)生(sheng)(sheng)(sheng)，在(zai)安裝或(huo)使用時(shi)(shi)應(ying)特別小心(xin)，所用工具應(ying)采(cai)取絕緣(yuan)措施(shi)，連線時(shi)(shi)應(ying)先將電(dian)(dian)(dian)(dian)池(chi)以外(wai)的電(dian)(dian)(dian)(dian)器連好，經檢查(cha)無短(duan)(duan)路(lu)，最后連上蓄(xu)電(dian)(dian)(dian)(dian)池(chi)，布(bu)線規范應(ying)良好絕緣(yuan)，防止重疊受壓產(chan)(chan)生(sheng)(sheng)(sheng)破裂。

　　4、防止連接松(song)動(dong)和不牢

　　若(ruo)(ruo)接(jie)(jie)(jie)觸(chu)(chu)不(bu)牢(lao)，程度較(jiao)(jiao)輕(qing)，會(hui)發(fa)生(sheng)導(dao)電(dian)(dian)(dian)不(bu)良，使(shi)其線(xian)路(lu)接(jie)(jie)(jie)觸(chu)(chu)部位(wei)發(fa)熱，線(xian)路(lu)損耗較(jiao)(jiao)大，輸出電(dian)(dian)(dian)壓偏低(di)，影響電(dian)(dian)(dian)機功(gong)率，使(shi)行駛里(li)程減(jian)少或不(bu)能(neng)正常騎行；若(ruo)(ruo)在(zai)接(jie)(jie)(jie)線(xian)端(duan)(duan)子部件接(jie)(jie)(jie)觸(chu)(chu)不(bu)牢(lao)(絕大多(duo)數故(gu)障(zhang)是(shi)在(zai)接(jie)(jie)(jie)線(xian)端(duan)(duan)與連線(xian)接(jie)(jie)(jie)頭部位(wei))，端(duan)(duan)子會(hui)大量發(fa)熱，影響端(duan)(duan)子與密封膠的(de)(de)結合，時間一長(chang)就會(hui)發(fa)生(sheng)漏(lou)液“爬酸”現象。若(ruo)(ruo)在(zai)行駛過(guo)程或充電(dian)(dian)(dian)過(guo)程中出現接(jie)(jie)(jie)觸(chu)(chu)不(bu)牢(lao)，可(ke)(ke)能(neng)產(chan)生(sheng)斷路(lu)，斷路(lu)時會(hui)產(chan)生(sheng)強烈的(de)(de)火(huo)花，可(ke)(ke)能(neng)點爆(bao)蓄(xu)電(dian)(dian)(dian)池內部的(de)(de)可(ke)(ke)爆(bao)氣體（特(te)別是(shi)剛(gang)充好電(dian)(dian)(dian)的(de)(de)蓄(xu)電(dian)(dian)(dian)池，因電(dian)(dian)(dian)池內可(ke)(ke)爆(bao)氣體較(jiao)(jiao)多(duo)，且蓄(xu)電(dian)(dian)(dian)池電(dian)(dian)(dian)量足，斷路(lu)時火(huo)花較(jiao)(jiao)強烈，爆(bao)炸的(de)(de)可(ke)(ke)能(neng)性(xing)相當大。）

　　電動車在運行時要承受較(jiao)為強烈的振動，因此，應對所有連(lian)接(jie)的可靠性(xing)進行考(kao)核(he)，接(jie)插件應帶“自(zi)鎖”功能，防止振動和拉(la)動時脫落，對與(yu)蓄電池(chi)接(jie)線(xian)(xian)片(pian)的連(lian)線(xian)(xian)應采取(qu)接(jie)插件，并用焊(han)錫(xi)將其焊(han)牢(lao)，接(jie)插件與(yu)連(lian)線(xian)(xian)應用壓(ya)接(jie)方式(shi)（也可壓(ya)接(jie)后(hou)再用焊(han)錫(xi)焊(han)一遍增加可靠性(xing)）。
