本发明公开了一种动力电池烟雾扩散装置，包括电池箱和装在电池箱内的电池装置，所述电池装置包括用于防火隔热的外壳、与外壳上端紧密接触的电池罩和装在外壳内部的电池本体，本发明结构简单，将多个动力电池有序组合，可减小电池箱的存放体积，提高空间利用率；当动力电池热失控时，可通过设置的条形磁铁、具有导磁性的烟雾板和电池罩，实现出烟口的自动开合，及时将热失控产生的热量从烟雾通道排出，提高了烟雾排出速度；同时，密闭腔体的设置可有效控制热失控扩展，避免烟雾对电池电极、连接片等的腐蚀，防止高温、烟雾等对动力电池造成损坏，保证其他动力电池的正常工作，有效延长了动力电池的使用寿命，降低了使用成本。 The invention discloses a smoke diffusion device for power batteries. The smoke diffusion device comprises a battery box and battery devices mounted in the battery box, wherein each battery device comprises a housing for fire resistance and heat insulation, a battery cover in close contact with the upper end of the housing and a battery body mounted in the housing. The smoke diffusion device is simple in structure, and as a plurality of power batteries are orderly combined, the storage size of the battery box can be reduced, and the space utilization ratio is improved; when the power batteriesare subject to thermal runaway, automatic opening and closing of smoke outlets can be realized by bar magnets, smoke plates with magn
