在臺鈴電動車“炫耀”的充(chong)電(dian)口有(you)發現‘220V強電(dian)、禁止觸碰’的標(biao)貼，這是(shi)是(shi)在(zai)之(zhi)前的電(dian)動車沒(mei)有(you)的。難道這是(shi)用(yong)來恐嚇小偷的嗎？難道跑150公里(li)用(yong)到了220V高壓(ya)電(dian)池？官方參數顯示這款炫耀電(dian)動車的電(dian)池電(dian)壓(ya)是(shi)48V啊？怎么回事呢？

這里普及一下鉛酸電(dian)(dian)(dian)池(chi)的(de)(de)充電(dian)(dian)(dian)器充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)要高(gao)于電(dian)(dian)(dian)池(chi)本身的(de)(de)電(dian)(dian)(dian)壓(ya)時候電(dian)(dian)(dian)流才能沖進(jin)去。常(chang)見的(de)(de)48V0V:V電(dian)(dian)(dian)池(chi)組是(shi)由(you)單塊(kuai)(kuai)12V的(de)(de)電(dian)(dian)(dian)池(chi)串聯(lian)起來(lai)的(de)(de)，拿48V來(lai)說(shuo)，是(shi)由(you)4塊(kuai)(kuai)12V的(de)(de)標準電(dian)(dian)(dian)池(chi)串聯(lian)，而(er)12V是(shi)電(dian)(dian)(dian)池(chi)的(de)(de)標準電(dian)(dian)(dian)池(chi)是(shi)由(you)6塊(kuai)(kuai)2V的(de)(de)極板(ban)串聯(lian)組合而(er)成，實際(ji)的(de)(de)電(dian)(dian)(dian)壓(ya)會隨著電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)量變化(hua)(hua)而(er)變化(hua)(hua)。

我(wo)們會在(zai)48V控(kong)制器(qi)上看到一(yi)個欠(qian)壓(ya)(ya)保護42V，就(jiu)是(shi)說低于42V時候為防止電(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(sun)害(hai)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)保護。這(zhe)時候的(de)單塊電(dian)(dian)(dian)(dian)池(chi)(chi)只有(you)10.5V電(dian)(dian)(dian)(dian)壓(ya)(ya)，滿電(dian)(dian)(dian)(dian)時候單塊電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)13.35V。也(ye)就(jiu)是(shi)說單塊電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)在(zai)10.5V-13.35V之間變化(hua)，同理可(ke)以(yi)算出48V電(dian)(dian)(dian)(dian)池(chi)(chi)組在(zai)實(shi)際使(shi)用中的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)在(zai)42V-53.4V之間，充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)要(yao)高于電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)最高電(dian)(dian)(dian)(dian)壓(ya)(ya)，48V電(dian)(dian)(dian)(dian)池(chi)(chi)組的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)在(zai)59.1--59.7V。

回歸(gui)正題(ti)，按照上述(shu)48V的(de)電池組配的(de)充電器的(de)輸出電壓應該是59V才對。怎(zen)么會出現220V的(de)字樣(yang)呢(ni)？原來炫(xuan)耀(yao)這款車采用的(de)內(nei)置式充電器，220V不(bu)是指(zhi)電池的(de)充電電壓，而是內(nei)置充電器的(de)電源電壓。

現在絕(jue)大多數電(dian)(dian)(dian)動(dong)車采用(yong)外置充(chong)電(dian)(dian)(dian)器(qi)，充(chong)電(dian)(dian)(dian)前要檢查電(dian)(dian)(dian)動(dong)車充(chong)電(dian)(dian)(dian)器(qi)及蓄電(dian)(dian)(dian)池組的電(dian)(dian)(dian)壓和容量(liang)標稱是(shi)否相符。充(chong)電(dian)(dian)(dian)時先插電(dian)(dian)(dian)池盒(he)插頭(tou)(tou)，再(zai)插插座(zuo)插頭(tou)(tou)。充(chong)電(dian)(dian)(dian)結束則(ze)反(fan)之，先拔插座(zuo)插頭(tou)(tou)，再(zai)拔電(dian)(dian)(dian)池盒(he)插頭(tou)(tou)。

外置充電(dian)(dian)(dian)器(qi)經常(chang)(chang)是要隨(sui)車帶(dai)的(de)，但是現在的(de)充電(dian)(dian)(dian)器(qi)設計(ji)卻(que)不耐強烈震(zhen)動(dong)，很多(duo)充電(dian)(dian)(dian)器(qi)經過(guo)振動(dong)以后，其內(nei)部的(de)電(dian)(dian)(dian)位器(qi)會漂移，使得整(zheng)個參(can)數改變，導致充電(dian)(dian)(dian)狀態(tai)不正常(chang)(chang)。

現(xian)在的(de)充電(dian)(dian)器一般都沒有防(fang)水設(she)計，在充電(dian)(dian)很保存的(de)時(shi)候要注意防(fang)水。還有充電(dian)(dian)要通風散熱，防(fang)止有物件遮(zhe)擋充電(dian)(dian)器風扇。

是不是挺(ting)麻煩(fan)，外置充(chong)電器(qi)的(de)BUG 還真(zhen)不少。所(suo)以炫耀采用(yong)了內(nei)置式(shi)充(chong)電器(qi)采用(yong)了防(fang)震設計，充(chong)電器(qi)固定在車身內(nei)部。使用(yong)優質(zhi)散(san)熱鋁合(he)金代(dai)替塑料外殼，更加防(fang)水，散(san)熱。減少了安全隱患。

內置充(chong)(chong)電器(qi)不必擔心是(shi)否忘帶充(chong)(chong)電器(qi)，不必擔心散熱防(fang)水(shui)的(de)(de)(de)注意事項，最為關(guan)鍵的(de)(de)(de)充(chong)(chong)電方便，當充(chong)(chong)電插座離車距離遠的(de)(de)(de)時候(hou)，因(yin)為線不夠長(chang)傳統外置充(chong)(chong)電器(qi)會掛在(zai)半空中(zhong)。隨時都有摔落(luo)的(de)(de)(de)危險(xian)。

你(ni)要做(zuo)的(de)只需(xu)要把(ba)充電(dian)(dian)(dian)線(xian)拿出(chu)來(lai)，先插好電(dian)(dian)(dian)動(dong)車一(yi)端充電(dian)(dian)(dian)口，再插好電(dian)(dian)(dian)源(yuan)插座就行啦！也許過不(bu)了(le)多(duo)久你(ni)只需(xu)要從(cong)電(dian)(dian)(dian)動(dong)車上抽(chou)出(chu)充電(dian)(dian)(dian)線(xian)，然后插在插座上就一(yi)切OK了(le)。當(dang)然這對炫耀(yao)的(de)車內空間設計提出(chu)了(le)更高的(de)要求了(le)！
