日前，一则网络视频显示：一台在地库中处于静止状态的特斯拉Model S突然全车冒烟，并在随后的几秒钟之间发生了爆炸，所幸未造成人员伤亡。
电动汽车工程师建议：电动汽车发生爆炸需要“满足”很多条件，但是一旦发生冒烟或者起火等状态，就不能再用灭火器或其它灭火工具灭火。因为很大可能会发生爆炸，如果仓促前去灭火，很容易对自身造成严重的人身伤害。
其实，电动车起火自燃并不是新鲜事，去年就多达40余起。值得注意的是，其它大部分品牌电动车起火，多数发生在充电或发生碰撞的情况下，但特斯拉都是在未碰撞、未充电的情况下发生。
专家表示：电动车起火原因无外乎是电池发生问题，电池包是由若干电芯组成，某些电芯在出厂时就会出现短路的情况，在经过多次充放电后，短路被进一步扩大，车辆的BMS（电池热管理）系统失效，导致整个电池包起火。
