All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 4, an embodiment of the present utility model discloses an energy storage container including a container body 100, a battery pack 300, and an exhaust pipe assembly 400.
Wherein, the container body 100 is internally provided with an installation cavity; the battery pack 300 is disposed in the installation cavity; the exhaust pipe assembly 400 communicates with the outside of the container body 100 and is hermetically connected with an explosion-proof valve of the battery pack 300; the protection level of the battery pack 300 is IP55 or more, or the whole of the battery pack 300 after the explosion-proof valve is connected to the exhaust pipe assembly 400 has IP55 or more protection level.
When the energy storage container provided by the utility model is used, as the installation cavity is arranged in the container body 100, the battery pack 300 is arranged in the installation cavity, and the exhaust pipe assembly 400 is communicated with the outside of the container body 100 and is in sealing connection with the explosion-proof valve of the battery pack 300; therefore, when the thermal runaway gas generation of the battery pack 300 occurs, a pressure difference is generated inside and outside the battery pack 300 based on the gas generated in the battery pack 300, so that the gas flow is discharged to the outside of the container body 100 after passing through the gas discharge pipe assembly 400.
