The invention relates to a battery box body, a battery pack and an electric vehicle, the battery box body comprises a tray used for placing a battery module, the tray comprises a tray bottom and four side walls surrounding the tray bottom to form a battery module placing area, at least one side wall is of a structure with a cavity, and the cavity is communicated with the tray bottom. At least one anti-explosion ventilation valve is installed on the inner side face of the structure, and at least one first through hole communicated with the cavity is formed in the bottom of the tray. When the battery cell is in thermal runaway and generates a large amount of gas, the pressure of the inner cavity of the battery box body is increased to the opening pressure of the anti-explosion ventilation valve, and the gas reaches the cavity through the anti-explosion ventilation valve and is discharged from the first through hole. Compared with the prior art, the method has the advantages of high safety and the like.
本发明涉及一种电池箱体、电池包和电动车,所述电池箱体包括用于放置电池模组的托盘,所述托盘包括托盘底部和在所述托盘底部围设形成放置电池模组区域的四个侧壁,至少一个所述侧壁为带有空腔的结构,该结构的内侧面上安装有至少一个防爆透气阀,所述托盘底部开设有至少一个与所述空腔连通的第一通孔。当电芯热失控产生大量气体时,电池箱体内腔压力增大到所述防爆透气阀的开启压力,气体通过所述防爆透气阀到达所述空腔内,并从所述第一通孔排出。与现有技术相比,本发明具有安全性高等优点。
