電動車起火事件并不是少數的孤例,反而發生頻率很高,且傷亡也很大。一輛小小的電瓶車會起火,而且還造成了這么大的傷亡率,它背后的原因,你們知道嗎?今天金環宇電線電纜小編和大家一起來看看電動車充電起火的原因都有哪些?
/1.電瓶起鼓/
電瓶起鼓(gu),也就(jiu)是俗說的“起泡(pao)”。一(yi)般(ban)來說,電瓶蓄電池(chi)在充電時,會因為高溫在電池(chi)內部產生高氣壓(ya),要讓氣壓(ya)散發出去(qu),就(jiu)需要有專(zhuan)用補充液(ye)來維持(chi)平衡。所以,一(yi)旦補充液(ye)分量不足(zu),電瓶就(jiu)很容(rong)易起鼓(gu)。
看(kan)電池是否會(hui)起鼓,可(ke)以通過觀察(cha)充(chong)電器指示燈的變化來(lai)判斷。如果電池長時(shi)(shi)間充(chong)電,卻一直不跳綠燈,但(dan)拔下電源插頭再插上電源時(shi)(shi),指示燈又會(hui)變綠。這時(shi)(shi)就(jiu)是提醒車主該添加補(bu)充(chong)液了。
電瓶(ping)起(qi)鼓以(yi)后,會(hui)影響電池正負極效(xiao)應,損害(hai)控制(zhi)器(qi),極易容易導(dao)致(zhi)充電器(qi)燒(shao)毀,引起(qi)火災。所(suo)以(yi),一旦發現電瓶(ping)指示(shi)燈出現問題,要(yao)及時(shi)引起(qi)注(zhu)意(yi)哦。
/2.私接電(dian)線/
現(xian)在住高(gao)層小區(qu)的家庭越來越多了,但是小區(qu)樓(lou)下要么沒有充電(dian)(dian)樁,要么覺得不經濟(ji)實惠,所(suo)以很多人想出(chu)了新招,私接(jie)電(dian)(dian)線!所(suo)以很多小區(qu)的電(dian)(dian)源線能從10樓(lou)接(jie)到(dao)1樓(lou),很是方便。
電(dian)線(xian)(xian)從(cong)高層(ceng)拉到(dao)樓下(xia),看似(si)聰明又省事,但(dan)它的潛(qian)在危險卻很嚴(yan)重。私拉電(dian)線(xian)(xian)容(rong)易導致電(dian)壓(ya)不(bu)穩,而且(qie)電(dian)線(xian)(xian)在空(kong)中沒有支撐(cheng),與墻角摩(mo)擦(ca)久了外皮會損壞,加上經常面(mian)臨日曬雨淋,特(te)別容(rong)易漏電(dian)。
/3.過度充(chong)電/
電(dian)(dian)(dian)動車的(de)電(dian)(dian)(dian)池較忌(ji)諱(hui)的(de)就(jiu)是(shi)過度充(chong)電(dian)(dian)(dian)、放電(dian)(dian)(dian)。過度充(chong)電(dian)(dian)(dian)會讓電(dian)(dian)(dian)池發(fa)熱、過量消耗電(dian)(dian)(dian)瓶(ping)內的(de)水分,使(shi)電(dian)(dian)(dian)瓶(ping)因缺水而容(rong)量漸漸下降,直至把電(dian)(dian)(dian)瓶(ping)充(chong)鼓,甚至導致(zhi)電(dian)(dian)(dian)池爆炸。
較佳的充(chong)電(dian)時(shi)間一般在8-10小時(shi)。可以等待綠燈亮了后(hou),再浮充(chong)2小時(shi)左右,然后(hou)切(qie)斷電(dian)源。尤其是對于已經使用(yong)幾年的電(dian)池來說,充(chong)電(dian)時(shi)要格外當心。
/4.充電器(qi)不匹配/
現在很多家庭不(bu)止一輛電(dian)(dian)動(dong)車(che),不(bu)同品牌的電(dian)(dian)動(dong)車(che)充(chong)電(dian)(dian)器千萬(wan)不(bu)要混合使(shi)用,不(bu)僅會給電(dian)(dian)動(dong)車(che)電(dian)(dian)池帶來損傷,也有可能(neng)會導致(zhi)電(dian)(dian)動(dong)車(che)起(qi)火,埋下(xia)安全隱患(huan)。
/5.私改電動車(che)/
有些車(che)主嫌棄電(dian)(dian)動車(che)跑得太慢,私(si)自(zi)撤(che)換電(dian)(dian)瓶,或(huo)者增壓電(dian)(dian)瓶的(de)馬力,這是極為(wei)(wei)危(wei)險的(de)行為(wei)(wei)。如果私(si)改,電(dian)(dian)瓶可能會因為(wei)(wei)長時間超負(fu)荷過大,而(er)引起線路發熱,從而(er)引發火災。
另外,如(ru)果(guo)線(xian)(xian)路(lu)(lu)(lu)受潮,或者線(xian)(xian)路(lu)(lu)(lu)脫落沒有及時維護,這(zhe)種情況容(rong)易造成(cheng)線(xian)(xian)路(lu)(lu)(lu)短路(lu)(lu)(lu)故(gu)障,也是很(hen)容(rong)易引(yin)發(fa)火災(zai)的,要引(yin)起重視(shi)哦。
有電動車(che)的小伙伴們(men),金(jin)環(huan)宇電線電纜小編建議大(da)家要注意一下這些問題哦!
/1.充(chong)電時(shi)注意通風/
電(dian)(dian)動車(che)在充(chong)電(dian)(dian)過程(cheng)中,充(chong)電(dian)(dian)器(qi)會(hui)產(chan)生大熱量,如果充(chong)電(dian)(dian)器(qi)被異(yi)物緊(jin)緊(jin)包(bao)裹,或(huo)者還有可燃(ran)物覆蓋在充(chong)電(dian)(dian)器(qi)或(huo)蓄電(dian)(dian)池上方,這樣(yang)容易損害充(chong)電(dian)(dian)器(qi)。充(chong)電(dian)(dian)器(qi)應該放(fang)在通風(feng)良好處(chu)充(chong)電(dian)(dian)。
/2.充電器不(bu)放后備箱/
為了方(fang)便,很多車(che)主會習慣把充電器放(fang)在后背箱中。但是這樣的話,充電器在行車(che)過程時,因為顛簸而受到震動,從而導(dao)致(zhi)其電子(zi)元件等受到損害,減(jian)少充電器使(shi)用壽命。
/3.電動(dong)車充電要及(ji)時/
有些車主暫時不用(yong)電(dian)(dian)(dian)動(dong)車時,就不給電(dian)(dian)(dian)動(dong)車充(chong)電(dian)(dian)(dian)。金環宇電(dian)(dian)(dian)線電(dian)(dian)(dian)纜小編告訴(su)大家,電(dian)(dian)(dian)動(dong)車充(chong)電(dian)(dian)(dian)一定要隨用(yong)隨充(chong),充(chong)電(dian)(dian)(dian)要及時。電(dian)(dian)(dian)池(chi)就怕虧(kui)電(dian)(dian)(dian),如果(guo)長期(qi)保持虧(kui)電(dian)(dian)(dian)狀態(tai),會(hui)極大損害電(dian)(dian)(dian)池(chi)使用(yong)的壽命。
/4.盡量不用(yong)快速充電站(zhan)/
現在很多城市的(de)街頭都會有快速充(chong)(chong)電(dian)(dian)(dian)站(zhan),快速充(chong)(chong)電(dian)(dian)(dian)站(zhan)的(de)工作原(yuan)理就是(shi)短時間大(da)電(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)。使用(yong)快速充(chong)(chong)電(dian)(dian)(dian)站(zhan)雖(sui)然能夠給(gei)車主(zhu)帶來一定的(de)方便,但是(shi)這(zhe)樣充(chong)(chong)電(dian)(dian)(dian)會導(dao)致電(dian)(dian)(dian)池失(shi)水嚴重,電(dian)(dian)(dian)池鼓(gu)包。所以如非緊急,盡量不要使用(yong)快充(chong)(chong)。
/5.電(dian)動車暴曬后不要立(li)馬(ma)充電(dian)/
如果是在夏季天氣炎熱的時(shi)候,電(dian)動(dong)(dong)車(che)放在太(tai)陽底(di)下(xia)暴(bao)(bao)曬以后不(bu)要立馬充電(dian),更不(bu)要直(zhi)接在太(tai)陽底(di)下(xia)暴(bao)(bao)曬充電(dian)。否則的話,會(hui)很容易造成電(dian)池(chi)開裂(lie)或(huo)變(bian)形(xing),導致電(dian)動(dong)(dong)車(che)自燃(ran)。
/6.盡量不放在室(shi)內充電/
如果(guo)電(dian)(dian)動(dong)車著(zhu)火,發生的(de)(de)后(hou)果(guo)是不可預計的(de)(de)。所以(yi)大家日(ri)常盡量(liang)不要(yao)把電(dian)(dian)車放在室內進行(xing)充(chong)電(dian)(dian),樓梯口(kou)、安(an)全出口(kou)等公共區域也不應(ying)該停放電(dian)(dian)動(dong)車,或者為(wei)電(dian)(dian)動(dong)車充(chong)電(dian)(dian)。
電動車是很多家(jia)庭(ting)的代(dai)步工(gong)具,平時一定要注意這些(xie)事(shi)情(qing),讓(rang)悲劇(ju)離我(wo)們遠(yuan)一點,再遠(yuan)一點!以上內容(rong)金(jin)環宇(yu)電線(xian)(xian)電纜小編(bian)就分享到這里,希(xi)望對大家(jia)有所幫助,更多資訊(xun)登(deng)陸(lu)深圳市金(jin)環宇(yu)電線(xian)(xian)電纜有限公司(si)網站(zhan)查詢!
