在臺鈴電動車“炫耀”的(de)(de)充電(dian)口(kou)有(you)發(fa)現‘220V強電(dian)、禁止(zhi)觸(chu)碰’的(de)(de)標貼，這是是在之(zhi)前的(de)(de)電(dian)動(dong)(dong)車沒有(you)的(de)(de)。難道這是用來(lai)恐嚇小偷(tou)的(de)(de)嗎(ma)？難道跑150公(gong)里用到(dao)了220V高壓電(dian)池(chi)？官方參數顯(xian)示(shi)這款炫耀電(dian)動(dong)(dong)車的(de)(de)電(dian)池(chi)電(dian)壓是48V啊？怎么回事呢(ni)？

這里普及一下鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓要高(gao)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)本身的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓時候電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流才能沖進去。常見的(de)(de)48V0V:V電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)是由(you)(you)單塊12V的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)串聯(lian)起來(lai)的(de)(de)，拿(na)48V來(lai)說，是由(you)(you)4塊12V的(de)(de)標準電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)串聯(lian)，而(er)12V是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)標準電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是由(you)(you)6塊2V的(de)(de)極板串聯(lian)組(zu)合而(er)成，實際的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓會隨著(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)變化而(er)變化。

我們(men)會(hui)在(zai)(zai)48V控制器(qi)(qi)上(shang)看到(dao)一個欠壓(ya)(ya)保(bao)(bao)護42V，就是說低于(yu)42V時(shi)(shi)候為防(fang)止電(dian)(dian)(dian)池過度放電(dian)(dian)(dian)造(zao)成電(dian)(dian)(dian)池損害的(de)電(dian)(dian)(dian)壓(ya)(ya)保(bao)(bao)護。這時(shi)(shi)候的(de)單(dan)塊(kuai)(kuai)電(dian)(dian)(dian)池只有(you)10.5V電(dian)(dian)(dian)壓(ya)(ya)，滿電(dian)(dian)(dian)時(shi)(shi)候單(dan)塊(kuai)(kuai)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)(ya)13.35V。也就是說單(dan)塊(kuai)(kuai)電(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)壓(ya)(ya)在(zai)(zai)10.5V-13.35V之間變化(hua)，同(tong)理(li)可以算(suan)出48V電(dian)(dian)(dian)池組在(zai)(zai)實(shi)際使用中的(de)電(dian)(dian)(dian)壓(ya)(ya)在(zai)(zai)42V-53.4V之間，充(chong)電(dian)(dian)(dian)器(qi)(qi)的(de)電(dian)(dian)(dian)壓(ya)(ya)要高(gao)于(yu)電(dian)(dian)(dian)池的(de)最高(gao)電(dian)(dian)(dian)壓(ya)(ya)，48V電(dian)(dian)(dian)池組的(de)充(chong)電(dian)(dian)(dian)器(qi)(qi)的(de)輸出電(dian)(dian)(dian)壓(ya)(ya)在(zai)(zai)59.1--59.7V。

回歸正(zheng)題(ti)，按照(zhao)上述(shu)48V的(de)電(dian)(dian)(dian)池組配(pei)的(de)充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)輸出(chu)電(dian)(dian)(dian)壓應該是(shi)59V才對(dui)。怎么(me)會出(chu)現220V的(de)字樣呢？原來炫耀這款車采用的(de)內(nei)置式充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)，220V不(bu)是(shi)指(zhi)電(dian)(dian)(dian)池的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓，而是(shi)內(nei)置充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓。

現在絕大多(duo)數電(dian)(dian)(dian)動(dong)車(che)采用外置充(chong)電(dian)(dian)(dian)器，充(chong)電(dian)(dian)(dian)前要(yao)檢(jian)查電(dian)(dian)(dian)動(dong)車(che)充(chong)電(dian)(dian)(dian)器及蓄電(dian)(dian)(dian)池組(zu)的電(dian)(dian)(dian)壓和容量標稱是否相(xiang)符(fu)。充(chong)電(dian)(dian)(dian)時(shi)先插(cha)(cha)(cha)電(dian)(dian)(dian)池盒(he)(he)插(cha)(cha)(cha)頭，再插(cha)(cha)(cha)插(cha)(cha)(cha)座插(cha)(cha)(cha)頭。充(chong)電(dian)(dian)(dian)結束則(ze)反之，先拔(ba)插(cha)(cha)(cha)座插(cha)(cha)(cha)頭，再拔(ba)電(dian)(dian)(dian)池盒(he)(he)插(cha)(cha)(cha)頭。

外置(zhi)充(chong)(chong)電器(qi)(qi)經(jing)常(chang)是要隨(sui)車帶的(de)，但是現在的(de)充(chong)(chong)電器(qi)(qi)設計卻不耐強烈震(zhen)動，很多充(chong)(chong)電器(qi)(qi)經(jing)過(guo)振動以后，其內部的(de)電位器(qi)(qi)會(hui)漂移(yi)，使得(de)整(zheng)個(ge)參數改變(bian)，導致充(chong)(chong)電狀(zhuang)態不正常(chang)。

現在的(de)充電(dian)(dian)器(qi)一般都沒有(you)防(fang)水設計(ji)，在充電(dian)(dian)很保存(cun)的(de)時候要注(zhu)意(yi)防(fang)水。還有(you)充電(dian)(dian)要通(tong)風散熱，防(fang)止有(you)物件遮擋充電(dian)(dian)器(qi)風扇。

是不是挺麻煩，外置充電器(qi)的BUG 還真不少(shao)。所(suo)以炫(xuan)耀采(cai)用(yong)(yong)(yong)了內置式充電器(qi)采(cai)用(yong)(yong)(yong)了防(fang)震設計，充電器(qi)固定在車身內部。使(shi)用(yong)(yong)(yong)優質散熱鋁合金代替塑料外殼(ke)，更加(jia)防(fang)水，散熱。減少(shao)了安全隱患。

內置充(chong)電(dian)器不必(bi)擔心是否忘帶(dai)充(chong)電(dian)器，不必(bi)擔心散熱防水的(de)注意事項，最為關(guan)鍵的(de)充(chong)電(dian)方便，當充(chong)電(dian)插座(zuo)離車(che)距離遠的(de)時候(hou)，因為線不夠長傳(chuan)統外置充(chong)電(dian)器會(hui)掛在半空中(zhong)。隨時都有(you)摔落的(de)危險。

你要(yao)做的只需要(yao)把充(chong)(chong)電(dian)線(xian)拿出來，先插好(hao)電(dian)動(dong)車(che)一(yi)端充(chong)(chong)電(dian)口，再插好(hao)電(dian)源插座(zuo)就行啦(la)！也許過不(bu)了(le)(le)多久你只需要(yao)從(cong)電(dian)動(dong)車(che)上抽出充(chong)(chong)電(dian)線(xian)，然后插在插座(zuo)上就一(yi)切OK了(le)(le)。當然這對炫(xuan)耀(yao)的車(che)內(nei)空(kong)間設計提出了(le)(le)更(geng)高(gao)的要(yao)求了(le)(le)！
