[0037] By providing a storage bin 21 for storing the fire extinguishing agent on the cover assembly 20 and providing a switch module 30 at the same time, it is not necessary to occupy the space in the first receiving tank 11 for installing the storage bin 21, thereby ensuring the compactness of the overall structure of the energy storage container; in addition, when the switch module 30 is located at the connection between the storage bin 21 and the first receiving tank 11, the switch module 30 can be used to control the connection between the storage bin 21 and the first receiving tank 11, so that the storage bin 21 is connected to the first receiving tank 11, and then the fire extinguishing agent in the storage bin 21 enters the first receiving tank 11, so as to achieve the purpose of extinguishing the battery cluster 12 in the first receiving tank 11; when the switch module 30 is located at the connection between the storage bin 21 and the battery pack 121, the switch module 30 can be used to control the connection between the storage bin 21 and the battery pack 121, so that the storage bin 21 is connected to the battery pack 121, so that the fire extinguishing agent in the storage bin 21 enters the battery pack 121, so as to achieve the purpose of extinguishing the battery pack 121.

[0038] It should be noted that, in the present application, the "on-off" in the above-mentioned "on-off module 30 is used to control the on-off between the agent storage bin 21 and the first containing tank 11" specifically means that when there is no fire-fighting need, the agent storage bin 21 and the first containing tank 11 are in a disconnected state, and when fire-fighting is required, the agent storage bin 21 and the first containing tank 11 are in a connected state.

[0039] Furthermore, the "on-off" in the above-mentioned "on-off module 30 controls the on-off between the agent storage bin 21 and the battery pack 121" specifically means that when there is no fire-fighting demand, the agent storage bin 21 and the battery pack 121 are in a disconnected state, and when fire-fighting is required, the agent storage bin 21 and the battery pack 121 are in a connected state.

[0045] Furthermore, the second switch structure is used to switch from a closed state to an open state when the temperature in the first containing tank 11 rises to a preset temperature, so as to connect the agent storage bin 21 and the first containing tank 11, so that the fire extinguishing agent in the agent storage bin 21 enters the first containing tank 11. In this way, compared with the electrically controlled first switch structure requiring the first detection module 40, the thermal material switch is a mechanical passive trigger structure, which does not need to rely on the first detection module 40 and the circuit, and has higher reliability than the electrically controlled switch.
