However, when the number of functional components such as the battery modules and the like is large, which leads to the significant increase of the load of the energy storage container 10, and meanwhile, the energy storage container 10 has to be increased in size, so that the length span of the foundation beam set 13 is too long, and the rigidity and strength are insufficient, by further additionally installing the additional beam set 14 on the foundation beam set 13, and connecting the opposite ends of the additional beam set 14 with the first frame 11 and the second frame 12 respectively, the additional beam set 14 can play a role in reinforcing the strength and rigidity of the foundation beam set 13, thereby improving the rigidity and strength of the foundation frame structure in the length direction, improving the load capacity of the energy storage container 10, avoiding serious deformation and even fracture caused by insufficient strength and rigidity in the length direction during transportation and hoisting, further causing the problem of extrusion damage to the battery modules, effectively eliminating potential safety hazards, and improving the safety and reliability of the energy storage container 10 and the energy storage system 100.

In addition, in this embodiment, the first additional beam 141 and the first foundation beam 131 are disposed at an included angle, and the specific first additional beam 141 and the first foundation beam 131 cooperate to form an angle steel structure.

Therefore, the integrated first additional beam 141 and first base beam 131 have both the strength and rigidity characteristics of the angle steel shape, thereby achieving the effect of increasing the strength and rigidity of the energy storage container 10 in the length direction. By adding a first additional beam 141 to the first foundation beam 131, the strength and rigidity of the energy storage container 10 in the length direction can be increased in a double manner, so that the structural mechanical properties of the energy storage container 10 are obviously optimized.

In addition, in this embodiment, the second additional beam 142 and the second foundation beam 132 are disposed at an included angle, and the second additional beam 142 and the second foundation beam 132 cooperate to form an angle structure.

Therefore, the integrated second additional beam 142 and second foundation beam 132 have both the strength and rigidity characteristics of the angle steel shape, thereby achieving the effect of increasing the strength and rigidity of the energy storage container 10 in the length direction. By adding a second additional beam 142 to the second base beam 132, the strength and rigidity of the energy storage container 10 in the length direction can be increased in a double manner, so that the structural mechanical properties of the energy storage container 10 are obviously optimized.

In addition, in this embodiment, the third additional beam 143 and the third foundation beam 133 are disposed at an included angle, and the specific third additional beam 143 and the third foundation beam 133 cooperate to form an angle steel structure.

By adding a third additional beam 143 to the third base beam 133, the strength and rigidity of the energy storage container 10 in the length direction can be increased in a double manner, so that the structural mechanical properties of the energy storage container 10 are obviously optimized.

In addition, in this embodiment, the fourth additional beam 144 and the fourth foundation beam 134 are disposed at an included angle, and the specific fourth additional beam 144 and the fourth foundation beam 134 cooperate to form an angle structure.

Therefore, the integrated fourth additional beam 144 and fourth base beam 134 have both the strength and rigidity characteristics of the angle steel shape, thereby achieving the effect of increasing the strength and rigidity of the energy storage container 10 in the length direction. By adding a fourth additional beam 144 to the fourth base beam 134, a dual increase in strength and rigidity of the energy storage container 10 in the length direction can be achieved, resulting in a significant optimization of the structural mechanical properties of the energy storage container 10.
