近广东地区暴(bao)雨不断,导致(zhi)很(hen)多地势低洼地区积水严重(zhong),无数的(de)车(che)辆需要涉(she)水行进,更甚(shen)至(zhi)被泡到了水里。而这时,问题出现了:即便是(shi)燃油车(che)型这么成熟的(de)车(che)型,在涉(she)水行驶时也有可能趴下(xia),那我的(de)新能源车(che)呢?它(ta)是(shi)否(fou)足够安全(quan),如果我没开(kai)车(che),电(dian)池泡在水里会(hui)不会(hui)报(bao)废?更甚(shen)至(zhi),会(hui)不会(hui)发生自燃?
电(dian)(dian)动(dong)汽车(che)(che)电(dian)(dian)池(chi)(chi)到底防不(bu)防水(shui),或者(zhe)说(shuo)怕(pa)不(bu)怕(pa)水(shui),其实主(zhu)要看三(san)个方面,电(dian)(dian)池(chi)(chi)、电(dian)(dian)池(chi)(chi)管(guan)理系(xi)统以及电(dian)(dian)池(chi)(chi)包(bao)。为什么这么说(shuo)呢?首(shou)先(xian),车(che)(che)辆涉水(shui)导致趴窝或者(zhe)损坏,它必然(ran)有一个路(lu)径(jing):水(shui)从(cong)车(che)(che)辆外部(bu)进入,先(xian)是(shi)接触(chu)到电(dian)(dian)池(chi)(chi)包(bao)外部(bu)的(de)(de)密封(feng)防护,突(tu)破防护之(zhi)后(hou)会进入第(di)二(er)层(ceng),即电(dian)(dian)池(chi)(chi)串联之(zhi)间的(de)(de)系(xi)统管(guan)理保护,后(hou)一道(dao)防线则是(shi)单个电(dian)(dian)池(chi)(chi)自(zi)身的(de)(de)防水(shui)能(neng)力(li)。这三(san)层(ceng)保护,构建起新能(neng)源汽车(che)(che)涉水(shui)性能(neng)的(de)(de)三(san)道(dao)防线。
因此,新能(neng)源汽车(che)到底(di)怕不怕水,我(wo)们(men)不能(neng)一(yi)(yi)概而论,每一(yi)(yi)款车(che),不同(tong)的电池、电池包与管理系统,都会导致防水性能(neng)出现(xian)差异。我(wo)们(men)首(shou)先从单(dan)个电池说起(qi),在这(zhei)里引(yin)入一(yi)(yi)个标(biao)准,那就是“IPX7”。IPX7是产品防护安全级别中的一个指标,这套标准是用来衡量产品的防护灰尘吸入和防护短暂浸泡能力的,而IPX7这个级别几乎是目前多数民用企业所能达到的高标准了。顺带一提的是,目前市面上的新能源汽车中的每一颗电池,其至少都达到了IPX7标准。
在电(dian)池系统和底盘整车组装制造中(zhong),厂家(jia)也考虑到各种应用环境和因素。包括了(le),水泡、高(gao)温、震动(dong)、颠簸、撞(zhuang)击、跌落等一系列问题。所以电(dian)池包做了(le)严(yan)格(ge)的密封措施。在正常(chang)情况下,水无法进入电(dian)池内部以及控制线(xian)路(lu)中(zhong)。
当然也不(bu)排除,因(yin)线(xian)路元器件(jian)老化(hua)以及物理破损,腐(fu)蚀性液体腐(fu)蚀后,电池(chi)的(de)防护能力减弱。从而增加安全(quan)隐患。
所以深圳市山木新能源(yuan)表(biao)示(shi);虽然(ran)在(zai)雨(yu)(yu)天和(he)(he)泡水情况,电池(chi)发生安全(quan)问(wen)题的概率很小,但依然(ran)建议下(xia)雨(yu)(yu)天停泊在(zai)较(jiao)高处。尽量不要在(zai)潮湿或阴雨(yu)(yu)露天环境(jing)下(xia)充电和(he)(he)使用(yong)。电池(chi)的技术(shu)也(ye)是在(zai)不断地进步当中(zhong)(zhong)。新能源(yuan)汽(qi)车(che)的安全(quan)性也(ye)会越来(lai)越有保(bao)障,起码在(zai)涉水性能上(shang),很多(duo)的标准和(he)(he)测试已经将其(qi)考虑(lv)(lv)周(zhou)全(quan),因此我们在(zai)日常用(yong)车(che)生活中(zhong)(zhong)其(qi)实不用(yong)顾虑(lv)(lv)太(tai)多(duo),更不应(ying)信谣传(chuan)谣。

光(guang)(guang)可(ke)以分为不同的波(bo)长,我们(men)可(ke)以透(tou)过彩虹看(kan)到(dao)。由于入射到(dao)电(dian)池上的光(guang)(guang)的光(guang)(guang)子(zi)能量(liang)范围非常(chang)宽,一(yi)些(xie)光(guang)(guang)子(zi)没有(you)足(zu)够的能量(liang)来(lai)形成电(dian)子(zi)-空穴对。它们(men)只是穿过电(dian)池,就像电(dian)池是透(tou)明(ming)的一(yi)样。但其他一(yi)些(xie)光(guang)(guang)子(zi)非常(chang)有(you)能量(liang)。只有(you)当(dang)达到(dao)一(yi)定的能量(liang)(电(dian)子(zi)伏特(eV),这取决于电(dian)池材料
近(jin)年来,大(da)多数的电(dian)(dian)(dian)子(zi)产品都使用锂(li)电(dian)(dian)(dian)池(chi)作为主要(yao)电(dian)(dian)(dian)源,锂(li)电(dian)(dian)(dian)池(chi)具有体(ti)积小(xiao)、能量密度(du)高、无记忆(yi)效应、循环寿(shou)命高、自放电(dian)(dian)(dian)率低、电(dian)(dian)(dian)压高等特(te)点,但其与(yu)镍镉(ge)、镍氢电(dian)(dian)(dian)池(chi)不同,在(zai)充电(dian)(dian)(dian)和放电(dian)(dian)(dian)时需要(yao)考虑(lv)安全性,因(yin)此(ci),针(zhen)对锂(li)电(dian)(dian)(dian)池(chi)的过充、放电(dian)(dian)(dian)、过流(liu)(liu)和短路电(dian)(dian)(dian)流(liu)(liu)保护显得更为重要(yao),因(yin)

锂(li)电(dian)(dian)(dian)(dian)(dian)池为什么会爆(bao)炸(zha)?1、过(guo)(guo)充:当电(dian)(dian)(dian)(dian)(dian)压超过(guo)(guo)4.2V以上时,电(dian)(dian)(dian)(dian)(dian)解液分解,产生(sheng)大量气体,电(dian)(dian)(dian)(dian)(dian)池压力升高(gao),过(guo)(guo)充负极(ji)表面锂(li)析出(chu),电(dian)(dian)(dian)(dian)(dian)池爆(bao)炸(zha)。2、高(gao)温环境(jing):锂(li)电(dian)(dian)(dian)(dian)(dian)池在高(gao)温环境(jing)下使(shi)(shi)用会膨(peng)胀,电(dian)(dian)(dian)(dian)(dian)解液分解。3、保护系统故障外接(jie)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)短路(lu)(lu)(lu):用户(hu)在使(shi)(shi)用时,外接(jie)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)短路(lu)(lu)(lu)导致电(dian)(dian)(dian)(dian)(dian)池爆(bao)炸(zha)
