[0049] Please refer to Figures 7 to 9 together, Figure 7 is a structural schematic diagram of the battery pack 200 in the energy storage system 1000 shown in Figure 1 when it is not completely assembled in the fixed assembly 120, Figure 8 is a structural schematic diagram of the battery pack 200 in the energy storage system 1000 shown in Figure 1 when it is completely assembled in the fixed assembly 120, and Figure 9 is a structural schematic diagram of the battery pack 200 in the energy storage system 1000 shown in Figure 1 when it is completely assembled in the fixed assembly 120 from another angle.

[0050] In the process of assembling the battery pack 200 to the container 100, the battery pack 200 can first be guided by the guide surface 121 of the guide portion 12 in the mounting frame 10 under the action of an external device, and the rollers 50 of the battery pack 200 can fall on the bearing surface 114 of the guide rail 11, wherein the first roller 50a can fall on the bearing surface 114 of the guide rail 11 in the first mounting frame 10a, and the second roller 50b can fall on the bearing surface 114 of the guide rail 11 in the second mounting frame 10b. Then, under the action of an external force, the first roller 50a of the battery pack 200 rolls on the bearing surface 114 of the guide rail 11 in the first mounting frame 10a, and the second roller 50b rolls on the bearing surface 114 of the guide rail 11 in the second mounting frame 10b, until the second limiting portion 13 of the mounting frame 10 is inserted into the limiting hole 407 of the battery pack 200, and the first abutting surface 135 of the second limiting portion 13 abuts against the second abutting surface 408 of the limiting hole 407.

[0051] It can be understood that, since the second limiting angle a is slightly smaller than 90 degrees, the distance L1 between the second abutting surface 408 and the fourth surface 402 is slightly greater than the maximum distance L2 between the first abutting surface 135 and the bearing surface 114, the second limiting surface 131 can guide the second limiting portion 13 to be inserted into the limiting hole 407 of the battery pack 200, the end of the battery pack 200 can be fixed by blind insertion, the assembly effect of the battery pack 200 is improved, and the mounting frame 10 can limit the battery pack 200 in the length direction and the height direction, thereby limiting the assembly of the battery pack 200 and ensuring the connection stability between the battery pack 200 and the mounting frame 10. In addition, since the battery pack 200 can be installed or removed by rolling friction between the rollers 50 and the bearing surface 114 of the guide rail 11, the manual pressure during the installation and removal of the battery pack 200 can be reduced, the whole process is convenient and fast, and the problem of being unable to maintain due to the large size of the battery pack 200 is avoided.

[0052] Finally, the insertion portion 22 of the fixing plate 20 is inserted into the insertion hole 115 of the mounting frame 10. Among them, the insertion portion 22 of the first fixing plate 20a is inserted into the insertion hole 115 of the first mounting frame 10a, and the insertion portion 22 of the second fixing plate 20b is inserted into the insertion hole 115 of the second mounting frame 10b. At this time, the first limiting surface 231 of the first limiting portion 23 of the fixing plate 20 abuts against the guide surface 121 of the guide portion 12 of the mounting frame 10 in cooperation, and the fixing hole 211 of the fixing portion 21 of the fixing plate 20 communicates with the mounting hole 406 of the battery pack 200. It can be understood that, since the first limiting angle d and the guide angle c are complementary angles, the first limiting surface 231 and the guide surface 121 are in plane cutting cooperation, and the pre-fixing of the battery pack 200 can be achieved.

[0053] In addition, the fixing assembly 120 further comprises a fixing member 30, which can be arranged in the fixing hole 211 of the fixing portion 21 of the fixing plate 20 and the mounting hole 406 of the battery pack 200, and is fixedly connected with the fixing portion 21 and the battery pack 200, so as to fix the battery pack 200 and realize the fixed connection between the battery pack 200 and the container 100. For example, the fixing member 30 can be a screw or a bolt.

[0054] In the embodiment, the fixing member 30 is two, and the two fixing members 30 are respectively a first fixing member 30a and a second fixing member 30b. The first fixing member 30a can be arranged in the fixing hole 211 of the first fixing plate 20a and the first mounting hole 406a of the battery pack 200, and is fixedly connected with the first fixing plate 20a and the battery pack 200. The second fixing member 30b can be arranged in the fixing hole 211 of the second fixing plate 20b and the second mounting hole 406b of the battery pack 200, and is fixedly connected with the second fixing plate 20b and the battery pack 200.

[0055] It can be understood that, in the assembling process of the battery pack 200 and the container 100 shown in the embodiment, after the battery pack 200 is assembled in place, the insertion portion 22 of the fixing plate 20 is inserted and matched with the insertion hole 115 of the mounting frame 10, and the first limiting portion 23 of the fixing plate 20 is abutted and matched with the guide portion 12 of the mounting frame 10.
