[0080] In the first embodiment of the present application, the inside of the bearing plate 130 can be provided with a heat exchange flow channel. On this basis, the heat exchange system 400 is communicated with the heat exchange flow channel of the bearing plate 130, and the heat exchange system 400 and the heat exchange flow channel circulate the heat exchange medium. Through the above design, the present application can further optimize the heat exchange effect of the bearing plate 130. In some embodiments, the bearing plate 130 can also not be provided with a flow channel, but only rely on the heat conduction performance of the material to realize heat exchange. Furthermore, the bearing plate 130 can also adopt other designs, for example, the heat exchange medium in the heat exchange system 400 can directly (for example, infiltrate) or indirectly contact the battery module 200 through phase change, capillary action and other principles, and is not limited to the present embodiment.

[0081] As shown in Figure 4 and Figure 5 , based on the design that the bearing plate 130 is provided with a heat exchange flow channel inside, in an embodiment of the present application, the bearing plate 130 can have a liquid inlet and a liquid outlet communicated with the heat exchange flow channel, and the heat exchange system can include a liquid inlet distribution pipe 410, a liquid outlet distribution pipe 420, a plurality of liquid inlet pipes 430 and a plurality of liquid outlet pipes 440.

Furthermore, the interface direction of the total liquid inlet 411 can also be adjustably arranged in the direction of 4x90°, and of course can also be arranged in other arbitrary angle directions according to the needs of connection.

[0083] As shown in Figure 3 and Figure 6 In an embodiment of the present application, the power connection device 300 can include a busbar assembly 310 and a power connector 320. Specifically, the busbar assembly 310 is arranged on one of the plurality of sides of the energy storage cabinet 100, and the busbar assembly 310 is electrically connected to the conductive busbars 210 of the plurality of battery modules 200. The power connector is arranged on the top plate 120 of the energy storage cabinet 100, and the power connector is electrically connected to the upper end of the busbar assembly 310.

[0084] As shown in Figure 7 Based on the design that the power connection device 300 includes the power connector, in an embodiment of the present application, the power connector 320 can include a housing 321 and a core 322. Specifically, the housing 321 has a mounting seat 3211 provided with a mounting channel 3212 penetrating the housing 321 in the vertical direction. The core 322 is arranged in the mounting channel 3212, and the core 322 is connected to the housing 321 via a buckle structure 3213. The power connector 320 is connected to the upper end of the busbar assembly 310 via the lower end of the core 322, and the power connector 320 is connected to the wiring 323 via the upper end of the core 322. Through the above design, the present application can realize the arrangement of the power connector 320 on the top of the battery pack, so as to meet the application needs of the shipborne battery pack and reduce the space occupation in the height direction. Moreover, the present application can use the buckle structure 3213 to improve the connection strength of the core 322 and the housing 321, so as to ensure that the power connector 320 has better connection stability.

[0085] As shown in Figure 8 and Figure 9 Based on the design that the power connection device 300 includes the busbar assembly 310, in an embodiment of the present application, the busbar assembly 310 can include a busbar body 311 and a switching busbar 312.

The first included angle a between the transition adjustment section 3123 and the first connecting section 3121 is greater than 90° and less than 180°. The second included angle β between the transition adjustment section 3123 and the second connecting section 3122 is greater than 90° and less than 180°. Through the above design, the busbar assembly 310 can be smoothly installed by adjusting the included angles of the transition adjustment section 3123 and the two connecting sections of the adapter bus 312. When the battery module 200 deviates in the horizontal direction or the vertical direction due to processing or installation errors, the busbar assembly 310 can be aligned with the corresponding mounting hole without being affected by the above deviation, avoiding damage and connection failure of the busbar assembly 310, and facilitating the stable operation of the shipborne energy storage unit A.
