在臺鈴電動車“炫(xuan)耀(yao)(yao)”的(de)充電(dian)(dian)(dian)口有(you)發現‘220V強電(dian)(dian)(dian)、禁止觸碰’的(de)標貼，這(zhe)是(shi)是(shi)在之前(qian)的(de)電(dian)(dian)(dian)動車(che)沒有(you)的(de)。難道這(zhe)是(shi)用來恐嚇(xia)小偷(tou)的(de)嗎？難道跑150公(gong)里(li)用到了(le)220V高壓(ya)電(dian)(dian)(dian)池？官(guan)方參數顯示這(zhe)款炫(xuan)耀(yao)(yao)電(dian)(dian)(dian)動車(che)的(de)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)是(shi)48V啊？怎么回事呢？

這里普及一下鉛酸電(dian)(dian)(dian)(dian)池的(de)充電(dian)(dian)(dian)(dian)器充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)要高于(yu)電(dian)(dian)(dian)(dian)池本身的(de)電(dian)(dian)(dian)(dian)壓(ya)時候(hou)電(dian)(dian)(dian)(dian)流才能沖進去。常見的(de)48V0V:V電(dian)(dian)(dian)(dian)池組(zu)是(shi)由(you)單塊(kuai)(kuai)12V的(de)電(dian)(dian)(dian)(dian)池串聯(lian)(lian)起(qi)來(lai)的(de)，拿48V來(lai)說(shuo)，是(shi)由(you)4塊(kuai)(kuai)12V的(de)標(biao)準(zhun)電(dian)(dian)(dian)(dian)池串聯(lian)(lian)，而12V是(shi)電(dian)(dian)(dian)(dian)池的(de)標(biao)準(zhun)電(dian)(dian)(dian)(dian)池是(shi)由(you)6塊(kuai)(kuai)2V的(de)極板串聯(lian)(lian)組(zu)合而成，實際的(de)電(dian)(dian)(dian)(dian)壓(ya)會隨著電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)量變化(hua)(hua)而變化(hua)(hua)。

我們(men)會在(zai)(zai)48V控制(zhi)器上看到一(yi)個欠壓(ya)(ya)(ya)(ya)(ya)(ya)保護(hu)42V，就(jiu)是(shi)說低(di)于42V時(shi)候為防止(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)過度放電(dian)(dian)(dian)(dian)造成(cheng)電(dian)(dian)(dian)(dian)池(chi)(chi)損害的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)保護(hu)。這(zhe)時(shi)候的(de)單(dan)塊電(dian)(dian)(dian)(dian)池(chi)(chi)只有10.5V電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)，滿電(dian)(dian)(dian)(dian)時(shi)候單(dan)塊電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)13.35V。也(ye)就(jiu)是(shi)說單(dan)塊電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)在(zai)(zai)10.5V-13.35V之間變化，同理(li)可(ke)以算出48V電(dian)(dian)(dian)(dian)池(chi)(chi)組在(zai)(zai)實際使用中的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)在(zai)(zai)42V-53.4V之間，充(chong)電(dian)(dian)(dian)(dian)器的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)要高(gao)于電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)最(zui)高(gao)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)，48V電(dian)(dian)(dian)(dian)池(chi)(chi)組的(de)充(chong)電(dian)(dian)(dian)(dian)器的(de)輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)在(zai)(zai)59.1--59.7V。

回歸正題，按照上述48V的(de)電(dian)池(chi)組(zu)配(pei)的(de)充(chong)電(dian)器的(de)輸出電(dian)壓(ya)應該是59V才(cai)對。怎(zen)么會出現220V的(de)字樣呢(ni)？原來炫耀這款車采用的(de)內(nei)置式充(chong)電(dian)器，220V不是指電(dian)池(chi)的(de)充(chong)電(dian)電(dian)壓(ya)，而是內(nei)置充(chong)電(dian)器的(de)電(dian)源電(dian)壓(ya)。

現在絕大多數(shu)電(dian)(dian)動車(che)采用(yong)外(wai)置充(chong)電(dian)(dian)器(qi)，充(chong)電(dian)(dian)前要檢查電(dian)(dian)動車(che)充(chong)電(dian)(dian)器(qi)及蓄電(dian)(dian)池組(zu)的電(dian)(dian)壓和(he)容量標稱(cheng)是否相符。充(chong)電(dian)(dian)時先插(cha)(cha)電(dian)(dian)池盒插(cha)(cha)頭，再(zai)插(cha)(cha)插(cha)(cha)座插(cha)(cha)頭。充(chong)電(dian)(dian)結(jie)束(shu)則反之，先拔插(cha)(cha)座插(cha)(cha)頭，再(zai)拔電(dian)(dian)池盒插(cha)(cha)頭。

外置充電器(qi)經常是要隨車帶的，但是現在的充電器(qi)設計(ji)卻不耐強(qiang)烈震動(dong)，很多(duo)充電器(qi)經過振動(dong)以后，其(qi)內部(bu)的電位器(qi)會漂移，使得整個(ge)參數改變，導致充電狀態不正常。

現在的充(chong)電器一(yi)般(ban)都沒有防水(shui)設計，在充(chong)電很保存的時(shi)候要(yao)注意防水(shui)。還(huan)有充(chong)電要(yao)通風(feng)散熱，防止有物(wu)件(jian)遮擋充(chong)電器風(feng)扇(shan)。

是不(bu)是挺麻(ma)煩，外置充電器的BUG 還真(zhen)不(bu)少(shao)。所以(yi)炫耀采用了內(nei)(nei)置式充電器采用了防震設(she)計，充電器固定在車身(shen)內(nei)(nei)部(bu)。使用優質散熱(re)鋁合(he)金代(dai)替(ti)塑料外殼(ke)，更(geng)加防水，散熱(re)。減少(shao)了安全隱(yin)患。

內置充(chong)電(dian)器(qi)(qi)(qi)不必(bi)(bi)擔(dan)心是(shi)否忘帶充(chong)電(dian)器(qi)(qi)(qi)，不必(bi)(bi)擔(dan)心散熱防水的(de)注意(yi)事項，最為(wei)關鍵(jian)的(de)充(chong)電(dian)方便，當充(chong)電(dian)插(cha)座離車距離遠的(de)時候，因為(wei)線不夠(gou)長傳統外置充(chong)電(dian)器(qi)(qi)(qi)會掛在半空中。隨時都有摔落的(de)危險(xian)。

你要(yao)做的只(zhi)需(xu)要(yao)把充(chong)電(dian)線(xian)拿出(chu)來，先插好電(dian)動車(che)一端充(chong)電(dian)口，再插好電(dian)源插座就行啦！也許過不了(le)多(duo)久(jiu)你只(zhi)需(xu)要(yao)從電(dian)動車(che)上抽出(chu)充(chong)電(dian)線(xian)，然后插在插座上就一切OK了(le)。當然這(zhe)對炫耀的車(che)內空間(jian)設計提出(chu)了(le)更高(gao)的要(yao)求了(le)！
