电动车在高温下(xia)充电会怎样

近(jin)全国各地的天(tian)气(qi)十分炎(yan)热，尤其是华北地区室(shi)外(wai)温度达(da)到了40摄氏(shi)(shi)度，地表温度达(da)(da)到(dao)(dao)了60摄氏(shi)(shi)度。甚(shen)至汽车在(zai)阳光下(xia)暴晒，汽车表面温度可以达(da)(da)到(dao)(dao)70摄氏(shi)(shi)度左右。

持续的高温不得不让(rang)人们担心高温天气下(xia)电(dian)动(dong)车充电(dian)会有什(shen)么(me)样的危(wei)险，为此山木电(dian)池（mottcellcell）详细为大家讲解下，避免安全问题的发生。减少潜在的隐患。

电动车(che)高温下(xia)充电，会加(jia)剧电池失水(shui)，电(dian)(dian)动汽车在行驶状态下(xia)，电(dian)(dian)池温(wen)度甚至可以达到70摄氏度(du)以上，如果他(ta)们(men)下来给电(dian)(dian)(dian)池(chi)充(chong)(chong)电(dian)(dian)(dian)，会增加(jia)电(dian)(dian)(dian)池(chi)的(de)耗水量，降低电(dian)(dian)(dian)池(chi)的(de)使用(yong)寿(shou)命，增加(jia)电(dian)(dian)(dian)池(chi)滚筒(tong)的(de)风险。电(dian)(dian)(dian)动车充(chong)(chong)电(dian)(dian)(dian)环(huan)境(jing)要求(qiu)相对较高(gao)，电(dian)(dian)(dian)动车车主需(xu)要选(xuan)择通(tong)风良好的(de)非直射阳光(guang)区，停(ting)止充(chong)(chong)电(dian)(dian)(dian)，禁止曝(pu)晒充(chong)(chong)电(dian)(dian)(dian)，或者(zhe)在闷热的(de)环(huan)境(jing)下充(chong)(chong)电(dian)(dian)(dian)，这样(yang)很容易(yi)使电(dian)(dian)(dian)池(chi)热量失去控制，引(yin)发自燃事(shi)故(gu)。

双高(gao)温(wen)，容易引起电(dian)(dian)(dian)池开裂变(bian)形(xing)在(zai)骑电(dian)(dian)(dian)单(dan)车(che)的(de)过(guo)程中会产生大量(liang)的(de)热量(liang)，即(ji)使(shi)电(dian)(dian)(dian)动车(che)刚刚停止，电(dian)(dian)(dian)池本身仍(reng)然处(chu)于不停的(de)加(jia)(jia)热阶段，再加(jia)(jia)上高(gao)温(wen)天气，如果电(dian)(dian)(dian)动车(che)立即(ji)充电(dian)(dian)(dian)，加(jia)(jia)倍的(de)高(gao)温(wen)往(wang)往(wang)会使(shi)线路(lu)温(wen)度恶(e)化，电(dian)(dian)(dian)单(dan)车(che)过(guo)热，甚(shen)至(zhi)引起电(dian)(dian)(dian)池开裂变(bian)形(xing)，从(cong)而(er)引发(fa)电(dian)(dian)(dian)路(lu)故障(zhang)，从(cong)而(er)引发(fa)自燃拓展信息：蓄电(dian)(dian)(dian)池在(zai)环境中的(de)温(wen)度超过(guo)60℃，随着蓄电池的升温(wen)，锂(li)电池有过热燃烧、爆炸的危险(xian)，但电动汽(qi)车(che)自(zi)(zi)燃的可能性(xing)很小，如(ru)果发(fa)生事故(gu)的主要原因是线路老化、短(duan)路。要避免电池损坏的危(wei)险，甚至自(zi)(zi)燃。电池在(zai)使用过程中对温度很敏感，锂电池的工作(zuo)温度范(fan)围(wei)为-20~60℃。在(zai)今天(tian)的(de)炎热天(tian)气里，电动汽车(che)尽量不(bu)在(zai)4102小时(shi)的(de)充电时(shi)间5261小时之(zhi)外直接冲(chong)进太阳(yang)

需要更好地维护电(dian)动(dong)汽车(che)(che)。车(che)(che)辆本身和充电(dian)装(zhuang)置都会过(guo)热(re)，并配备了BMS系统来(lai)控(kong)制(zhi)电(dian)(dian)(dian)(dian)(dian)压(ya)和电(dian)(dian)(dian)(dian)(dian)力，并协调车辆的(de)需求(qiu)和供应平衡。理(li)论(lun)上，电(dian)(dian)(dian)(dian)(dian)动汽车是可以安全充电(dian)(dian)(dian)(dian)(dian)的(de)，但(dan)它(ta)并不排除高温(wen)环(huan)境下的(de)线路老化等危害。正确的(de)做法是电(dian)(dian)(dian)(dian)(dian)动车不立即(ji)停止充电(dian)(dian)(dian)(dian)(dian)，在(zai)电(dian)(dian)(dian)(dian)(dian)池冷却半(ban)个(ge)多小时(shi)后首(shou)先停止充电(dian)(dian)(dian)(dian)(dian)，此(ci)外，当充电(dian)(dian)(dian)(dian)(dian)变成绿(lv)色(se)时(shi)，要(yao)尽快停止充电(dian)(dian)(dian)(dian)(dian)，注(zhu)意充电(dian)(dian)(dian)(dian)(dian)应选择通风(feng)凉爽(shuang)的(de)环(huan)境，每天按照规定(ding)的(de)里(li)程严格控(kong)制(zhi)充电(dian)(dian)(dian)(dian)(dian)时(shi)间。
