The utility model relates to a battery fireproof device. The battery fireproof device comprises a sealed box body and at least two single batteries, wherein the single batteries are in the sealed box body and in non-contact with the side wall of the box body, a gap communicated with an inner cavity of the box body and used for exhausting air is formed between the adjacent single batteries, and an inert gas injection port and an air outlet are formed in the box body. According to the battery fireproof device, the surrounding air of every battery can be completely exhausted effectively, the problem that the air can not be exhausted completely caused by the close arrangement of adjacent batteries is solved, and every place of the box body is filled with inert gases. According to the battery fireproof device, on the premise of not breaking the waterproof grade of the box body, an inert gas atmosphere is created in the battery fireproof device, and therefore, when the battery heating reaches the ignition condition, because no oxygen is in the box body, the battery can not make contact with the oxygen and burn.
