The lithium ion battery charge and discharge cycle life and safety are greatly affected by temperature. When the temperature of the battery cell is too large or the temperature difference is large, the cycle life of the battery cell will be greatly reduced, which affects the service life of the energy storage product, and in severe cases, the battery cell will cause thermal runaway. When the battery cell occurs thermal runaway, a large amount of flammable gas is generated. When the content of flammable gas reaches a certain concentration, it is very easy to explode when encountering a slight spark, causing great loss of personnel and property. Therefore, in the energy storage application scene, a ventilation and explosion venting device for discharging flammable gas is needed to ensure safety.

At present, the energy storage system almost increases the fan at the ventilation and exhaust air inlet and directly stacks the push rod, which stacks the two types of design. Such structure design has the following shortcomings: first, the fan blade of the air inlet and outlet is stacked with the push rod, which often leads to a too deep volume of the explosion venting port, so that the exhaust air inlet cannot be made ultra-thin, and the design space is limited. The second is that the air inlet and outlet suddenly lose power, which causes the baffle to not close back in time, and the fire extinguishing agent in the battery cabin flows from this place when the gas fire extinguishing starts, which cannot reach the fire extinguishing concentration and immersion time requirement, or the heavy (heavy) rain from the air inlet and outlet blows into the battery cabin, causing the battery cabin to be flooded and the electrical devices to fail.
