The embodiment of the invention provides a battery module explosion-proof structure and a battery module explosion-proof control method, and the battery module explosion-proof structure comprises a battery box used for placing a battery cell; a gas generation assembly which is arranged in the battery box and is used for releasing gas in the battery box so as to increase the pressure in the battery box;a and an explosion-proof valve which is mounted on the battery box, wherein the explosion-proof valve is opposite to a gas outlet of the gas generation assembly, and the explosion-proof valve is used for releasing the pressure in the battery box when the pressure in the battery box is greater than a pressure threshold value. The gas generation assembly and the explosion-proof valve are combined for use, the gas generation assembly generates gas to actively increase the pressure in the battery box, the explosion-proof valve is forced to be opened in advance to release the gas, the pressure in the battery box is reduced, explosion of the battery module is avoided, and the safety of the battery module is guaranteed.
本发明实施例提供了一种电池模组防爆结构和电池模组防爆控制方法,所述电池模组防爆结构包括:电池箱,用于放置电芯;安装在所述电池箱内的气体发生组件,用于在所述电池箱内释放气体,以增大所述电池箱内的压力;安装在所述电池箱上的防爆阀,所述防爆阀正对所述气体发生组件的气体出口,所述防爆阀用于在所述电池箱内的压力大于压力阈值时,释放所述电池箱内的压力。通过将气体发生组件与防爆阀联合使用,气体发生组件产生气体主动增加电池箱内的压力,迫使防爆阀提前打开来释放气体,降低电池箱内的压力避免电池模组发生爆炸,保障了电池模组的安全性。
