在臺鈴電動車“炫耀(yao)”的(de)(de)充電(dian)口(kou)有(you)發(fa)現‘220V強電(dian)、禁(jin)止觸(chu)碰’的(de)(de)標(biao)貼，這是(shi)是(shi)在之前的(de)(de)電(dian)動車(che)沒(mei)有(you)的(de)(de)。難(nan)道這是(shi)用來恐(kong)嚇小偷的(de)(de)嗎(ma)？難(nan)道跑150公里用到了220V高壓電(dian)池(chi)？官方(fang)參數(shu)顯示這款(kuan)炫耀(yao)電(dian)動車(che)的(de)(de)電(dian)池(chi)電(dian)壓是(shi)48V啊(a)？怎么回事(shi)呢(ni)？

這(zhe)里(li)普及一下鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓要高(gao)于電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)本(ben)身(shen)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓時(shi)候電(dian)(dian)(dian)(dian)(dian)(dian)流才能(neng)沖進(jin)去(qu)。常(chang)見的(de)(de)48V0V:V電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)是(shi)由單(dan)塊12V的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)串(chuan)聯(lian)起來(lai)的(de)(de)，拿(na)48V來(lai)說，是(shi)由4塊12V的(de)(de)標準電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)串(chuan)聯(lian)，而12V是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)標準電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)由6塊2V的(de)(de)極板串(chuan)聯(lian)組(zu)合而成，實(shi)際的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓會隨(sui)著電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量變化(hua)而變化(hua)。

我們會在(zai)(zai)48V控制器(qi)上看到一個欠壓(ya)(ya)(ya)保(bao)護(hu)42V，就(jiu)是(shi)說低(di)于42V時候為防止電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過度放電(dian)(dian)(dian)(dian)(dian)造成(cheng)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)損(sun)害的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)保(bao)護(hu)。這時候的(de)單塊電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)只有10.5V電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，滿電(dian)(dian)(dian)(dian)(dian)時候單塊電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)13.35V。也(ye)就(jiu)是(shi)說單塊電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)在(zai)(zai)10.5V-13.35V之(zhi)間變(bian)化，同理可以算出48V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組在(zai)(zai)實際使(shi)用中的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)在(zai)(zai)42V-53.4V之(zhi)間，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)要(yao)高于電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)最高電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，48V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)在(zai)(zai)59.1--59.7V。

回歸(gui)正(zheng)題，按(an)照(zhao)上述48V的電(dian)池組(zu)配的充電(dian)器(qi)(qi)的輸出電(dian)壓應該是59V才對。怎么會出現220V的字(zi)樣呢？原來炫耀這款車采用的內置式充電(dian)器(qi)(qi)，220V不(bu)是指電(dian)池的充電(dian)電(dian)壓，而是內置充電(dian)器(qi)(qi)的電(dian)源電(dian)壓。

現在絕大多(duo)數電(dian)(dian)動車(che)采用外置充電(dian)(dian)器，充電(dian)(dian)前要檢查(cha)電(dian)(dian)動車(che)充電(dian)(dian)器及蓄電(dian)(dian)池(chi)組的電(dian)(dian)壓和容量標稱是否相符。充電(dian)(dian)時先插(cha)電(dian)(dian)池(chi)盒(he)插(cha)頭，再插(cha)插(cha)座插(cha)頭。充電(dian)(dian)結(jie)束(shu)則反之，先拔插(cha)座插(cha)頭，再拔電(dian)(dian)池(chi)盒(he)插(cha)頭。

外(wai)置(zhi)充(chong)電器經(jing)常是要隨車帶(dai)的(de)(de)，但是現在的(de)(de)充(chong)電器設計(ji)卻不耐強烈震動，很多充(chong)電器經(jing)過振動以后，其內部的(de)(de)電位器會漂移，使得整個參數(shu)改變，導(dao)致充(chong)電狀態(tai)不正常。

現在(zai)(zai)的充(chong)電器一般都沒有(you)防水(shui)設計，在(zai)(zai)充(chong)電很保存的時候要注(zhu)意防水(shui)。還有(you)充(chong)電要通風散熱，防止有(you)物件遮擋(dang)充(chong)電器風扇。

是不(bu)是挺(ting)麻煩(fan)，外(wai)置(zhi)充(chong)電(dian)器(qi)(qi)的BUG 還真不(bu)少。所(suo)以炫耀采用(yong)了內置(zhi)式充(chong)電(dian)器(qi)(qi)采用(yong)了防震設計，充(chong)電(dian)器(qi)(qi)固定在車身內部(bu)。使(shi)用(yong)優質散熱(re)鋁合金(jin)代替塑料外(wai)殼，更加防水(shui)，散熱(re)。減少了安全隱患(huan)。

內置(zhi)充(chong)(chong)電(dian)器不(bu)(bu)(bu)必(bi)擔心是否忘帶充(chong)(chong)電(dian)器，不(bu)(bu)(bu)必(bi)擔心散熱防(fang)水的(de)注意事項，最為(wei)關鍵的(de)充(chong)(chong)電(dian)方便，當充(chong)(chong)電(dian)插座離車距離遠(yuan)的(de)時候，因為(wei)線(xian)不(bu)(bu)(bu)夠(gou)長傳統外置(zhi)充(chong)(chong)電(dian)器會掛在(zai)半空中(zhong)。隨時都有摔(shuai)落的(de)危險(xian)。

你(ni)要(yao)(yao)做的(de)(de)只(zhi)需要(yao)(yao)把充電(dian)線拿(na)出(chu)來，先插(cha)(cha)好電(dian)動(dong)車一端充電(dian)口(kou)，再(zai)插(cha)(cha)好電(dian)源插(cha)(cha)座(zuo)就(jiu)行啦！也(ye)許過不了(le)多久(jiu)你(ni)只(zhi)需要(yao)(yao)從(cong)電(dian)動(dong)車上(shang)抽(chou)出(chu)充電(dian)線，然(ran)后插(cha)(cha)在插(cha)(cha)座(zuo)上(shang)就(jiu)一切OK了(le)。當然(ran)這對炫耀(yao)的(de)(de)車內空(kong)間設計(ji)提出(chu)了(le)更高的(de)(de)要(yao)(yao)求了(le)！
