在臺鈴電動車“炫(xuan)耀”的充電(dian)口有發(fa)現‘220V強電(dian)、禁止觸碰’的標貼(tie)，這是(shi)(shi)是(shi)(shi)在之前的電(dian)動車(che)(che)沒有的。難道(dao)這是(shi)(shi)用來恐(kong)嚇(xia)小偷的嗎？難道(dao)跑150公里(li)用到(dao)了220V高壓電(dian)池(chi)？官方參數顯(xian)示這款炫(xuan)耀電(dian)動車(che)(che)的電(dian)池(chi)電(dian)壓是(shi)(shi)48V啊(a)？怎么回事呢(ni)？

這(zhe)里(li)普及一下鉛(qian)酸電(dian)(dian)(dian)池(chi)的充電(dian)(dian)(dian)器(qi)充電(dian)(dian)(dian)電(dian)(dian)(dian)壓要高(gao)于電(dian)(dian)(dian)池(chi)本(ben)身的電(dian)(dian)(dian)壓時候電(dian)(dian)(dian)流(liu)才能(neng)沖進去。常見的48V0V:V電(dian)(dian)(dian)池(chi)組(zu)是(shi)由單(dan)塊12V的電(dian)(dian)(dian)池(chi)串(chuan)聯起(qi)來的，拿48V來說，是(shi)由4塊12V的標(biao)準電(dian)(dian)(dian)池(chi)串(chuan)聯，而(er)12V是(shi)電(dian)(dian)(dian)池(chi)的標(biao)準電(dian)(dian)(dian)池(chi)是(shi)由6塊2V的極板串(chuan)聯組(zu)合(he)而(er)成，實際的電(dian)(dian)(dian)壓會隨著電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)量變化(hua)而(er)變化(hua)。

我(wo)們會在48V控(kong)制器(qi)上(shang)看到一(yi)個欠(qian)壓保護42V，就是說(shuo)低于(yu)42V時(shi)候為(wei)防止電(dian)(dian)(dian)池過度放電(dian)(dian)(dian)造成電(dian)(dian)(dian)池損害的(de)(de)電(dian)(dian)(dian)壓保護。這時(shi)候的(de)(de)單塊(kuai)電(dian)(dian)(dian)池只(zhi)有10.5V電(dian)(dian)(dian)壓，滿電(dian)(dian)(dian)時(shi)候單塊(kuai)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓13.35V。也就是說(shuo)單塊(kuai)電(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)壓在10.5V-13.35V之(zhi)間變化(hua)，同理可以算出(chu)48V電(dian)(dian)(dian)池組在實際使用中的(de)(de)電(dian)(dian)(dian)壓在42V-53.4V之(zhi)間，充(chong)電(dian)(dian)(dian)器(qi)的(de)(de)電(dian)(dian)(dian)壓要高(gao)于(yu)電(dian)(dian)(dian)池的(de)(de)最高(gao)電(dian)(dian)(dian)壓，48V電(dian)(dian)(dian)池組的(de)(de)充(chong)電(dian)(dian)(dian)器(qi)的(de)(de)輸出(chu)電(dian)(dian)(dian)壓在59.1--59.7V。

回歸正題，按照上述48V的(de)(de)電(dian)(dian)池組配的(de)(de)充(chong)電(dian)(dian)器的(de)(de)輸出電(dian)(dian)壓應(ying)該是(shi)59V才對。怎么(me)會出現220V的(de)(de)字(zi)樣呢？原來炫耀這款車采用的(de)(de)內(nei)置式充(chong)電(dian)(dian)器，220V不是(shi)指電(dian)(dian)池的(de)(de)充(chong)電(dian)(dian)電(dian)(dian)壓，而是(shi)內(nei)置充(chong)電(dian)(dian)器的(de)(de)電(dian)(dian)源電(dian)(dian)壓。

現在絕大多數電動車(che)采(cai)用外置充(chong)電器，充(chong)電前要檢查(cha)電動車(che)充(chong)電器及蓄(xu)電池(chi)組的(de)電壓和容(rong)量標稱是否相符。充(chong)電時先(xian)(xian)插(cha)(cha)(cha)電池(chi)盒插(cha)(cha)(cha)頭(tou)，再插(cha)(cha)(cha)插(cha)(cha)(cha)座插(cha)(cha)(cha)頭(tou)。充(chong)電結(jie)束(shu)則反之，先(xian)(xian)拔(ba)插(cha)(cha)(cha)座插(cha)(cha)(cha)頭(tou)，再拔(ba)電池(chi)盒插(cha)(cha)(cha)頭(tou)。

外(wai)置充(chong)電器經(jing)常(chang)是(shi)要隨(sui)車帶的，但是(shi)現在的充(chong)電器設計卻不(bu)耐強烈震動，很多充(chong)電器經(jing)過(guo)振動以后，其(qi)內部的電位(wei)器會漂移，使得整(zheng)個參數改變(bian)，導致充(chong)電狀態不(bu)正常(chang)。

現在(zai)的(de)充(chong)(chong)電器(qi)一般都沒有防(fang)水設計，在(zai)充(chong)(chong)電很(hen)保存的(de)時(shi)候要(yao)注意防(fang)水。還(huan)有充(chong)(chong)電要(yao)通風散熱，防(fang)止有物件遮(zhe)擋充(chong)(chong)電器(qi)風扇。

是不(bu)是挺麻煩，外(wai)置充電(dian)器(qi)(qi)的BUG 還真不(bu)少(shao)。所以炫耀(yao)采用(yong)了(le)內置式(shi)充電(dian)器(qi)(qi)采用(yong)了(le)防震(zhen)設計(ji)，充電(dian)器(qi)(qi)固定在車身內部(bu)。使用(yong)優質散熱(re)鋁合金(jin)代替(ti)塑料外(wai)殼，更加防水，散熱(re)。減少(shao)了(le)安全隱患(huan)。

內置(zhi)充電器(qi)(qi)不(bu)(bu)(bu)必擔(dan)(dan)心是否忘帶充電器(qi)(qi)，不(bu)(bu)(bu)必擔(dan)(dan)心散熱防(fang)水的(de)(de)注(zhu)意事項，最為關鍵(jian)的(de)(de)充電方便，當(dang)充電插座離(li)車距離(li)遠的(de)(de)時候，因為線(xian)不(bu)(bu)(bu)夠長傳統外置(zhi)充電器(qi)(qi)會掛在半空中。隨時都有摔(shuai)落(luo)的(de)(de)危險。

你要(yao)做的(de)只需要(yao)把充(chong)(chong)電(dian)(dian)(dian)線拿出來，先插好電(dian)(dian)(dian)動車(che)一(yi)端充(chong)(chong)電(dian)(dian)(dian)口，再插好電(dian)(dian)(dian)源(yuan)插座就(jiu)行啦(la)！也許過不了(le)多久你只需要(yao)從電(dian)(dian)(dian)動車(che)上抽(chou)出充(chong)(chong)電(dian)(dian)(dian)線，然(ran)(ran)后(hou)插在插座上就(jiu)一(yi)切(qie)OK了(le)。當(dang)然(ran)(ran)這對炫(xuan)耀(yao)的(de)車(che)內空間設計提(ti)出了(le)更高的(de)要(yao)求了(le)！
