近期有报道称,美国纽约市2022年共发生200多起电动车火灾,是第三大火灾原因。英国有数据称每1.5万辆电动车中就有一辆会着火。

电动车为什么易着火,如何应对?

简单来说,电动车使用的锂电池体积小重量轻,“浓缩”着大量能量,如果发生故障就非常易燃。近几年电动车持有量飞速增长,隐患就更大了。

避免着火,首先要使用专用电池及充电器,而不是其他廉价品替代;不要居民楼内充电,充电2—6小时后需拔掉插头,过度充电影响电池寿命,易引发过热。电池平时应存放在阴凉干燥处,避免高温;避免刺破损坏电池,更不要自行修理;定期检查电池是否鼓包或泄漏,若有损坏过热需找专业人员处理。

锂电池燃烧时灭火难度非常大。综合多个消防类科普内容,它不能用干粉灭火器扑救,否则隔绝对流加剧电池过热;有时可用大量水扑救,但需警惕短路风险;明火扑灭后还容易复燃。因此自行灭火非常危险,应由消防处理。保护自己、警示他人、撤掉其他易燃物,等消防人员灭火是最安全稳妥的解决方式。
