As shown in fig. 17, the energy storage system 200 according to an embodiment of the present invention may include a plurality of the energy storage modules 100 of the energy storage system 200 according to an embodiment of the present invention.
In some embodiments, the number of the plurality of electrical storage modules 100 in the energy storage system 200 may be adjusted according to the required capacity, and the arrangement manner of the plurality of electrical storage modules 100 may be adjusted according to the installation site requirement of the energy storage system 200. For example, the plurality of power storage modules 100 may be arranged in a "straight" shape, a "cross" shape, a "T" shape, an "L" shape, a polygonal ring shape, or the like.

Specifically, the independent case 10 is a seal structure, and the independent case 10 includes a case body 11 and a door body 12. The housing body 11 has a receiving chamber 111, and the door body 12 is used to open and close a chamber opening of the receiving chamber 111 to facilitate installation, replacement, and maintenance of the battery pack 20. When the door body 12 closes the opening of the accommodating cavity 111, the door body 12 may seal the opening of the accommodating cavity 111 to achieve sealing of the independent casing 10. Further, the battery pack 20 is mounted in the housing cavity 111.
The sealing structure of the independent housing 10 can prevent external insects, sand blown by wind and the like from entering the accommodating cavity 111, thereby preventing the sand blown by wind from causing the electricity storage module 100 to report false fire alarm, causing the energy storage system 200 to work abnormally, and even causing the electricity storage module 100 to fight fire and causing the damage of the electricity storage module 100, improving the accuracy of fire detection, and improving the safety and normal work of the electricity storage module 100.

In some embodiments of the invention, the liquid cooling lines of a plurality of the electric storage modules 100 may be connected by a cooling connection that connects at least two electric storage modules 100 in a manner that is at least partially disposed outside of the independent housing 10 to cool the electric storage modules 100. Therefore, the cooling medium of the plurality of electricity storage modules 100 can be conveniently communicated, the energy storage system 100 is formed into an integral cooling system, the sealing arrangement of the independent shell 10 can be conveniently realized, too much space in the independent shell 10 can be prevented from being occupied by the cooling connecting part, and the energy density of the electricity storage modules 100 can be conveniently improved.
And, the electricity storage module 100 can also control the condition of a fire at the conflagration source, and when the group battery 20 in holding chamber 111 takes place the thermal runaway, the seal structure of independent shell 10 can be isolated with the intensity of a fire and external world, avoids the condition of a fire of the electricity storage module 100 who takes place the conflagration to stretch to other electricity storage modules 100 of energy storage system 200, avoids appearing the conflagration chain reaction, avoids causing great fire loss, and has reduced fire control pressure.

The electric storage module 100 of the energy storage system 200 of the invention avoids the spread of fire through a sealing structure, and can directly inject water into the accommodating cavity 111 to realize fire fighting after the fire occurs, without opening the door body 12, thereby avoiding explosion. For example, in some embodiments, a fire fighting assembly is further disposed in the independent housing 10 of the power storage module 100, the fire fighting assembly is configured to spray a fire extinguishing medium to the target power storage module 100, and the fire extinguishing medium is limited by an independent closed space formed by the independent housing 10 of the target power storage module 100, so as to prevent the fire extinguishing medium from spreading to other power storage modules 100 adjacent to the target power storage module 100, so as to achieve independent, targeted and timely fire fighting, thereby not only performing fire early warning and fire extinguishing quickly and effectively, avoiding damage to other power storage modules 100 in the energy storage system 200, and avoiding explosion caused by opening a door when a fire occurs.
