The base 01 has a short-circuit connection function; its positive and negative output terminals are electrically connected to the bottom battery module 02. The top battery management module 03 is equipped with a circuit breaker 03-1.

[0003] When assembling the energy storage cabinet, first install the bottom base 01, then install the battery modules 02 from top to bottom, and finally install the top battery management module 03.

[0073] Specifically, the top cover 4 has reserved interface positions for the first positive terminal 5-1 and the first negative terminal 5-2 of the power conversion module 5 on its side, top, or bottom.

[0074] When there are multiple battery components 2, all battery components 2 are respectively the first battery component, the second battery component, ... the (M-1)th battery component, and the Mth battery component, wherein the first battery component, the second battery component, ... the (M-1)th battery component, and the Mth battery component are stacked sequentially from bottom to top.

[0075] Each battery assembly 2 is provided with a first terminal 2-13 and a second terminal 2-14 located at the top of the battery assembly 2, and a third terminal 2-15 and a fourth terminal 2-16 located at the bottom of the battery assembly 2.

[0082] In this application, the battery management module 3 is preferably placed on the side wall of the battery assembly 2, on the upper part of the base 1. Preferably, the projection of the top cover 4, the battery assembly 2 and the battery management module 3 is located within the projection of the base 1 from top to bottom.

[0083] As described above, in the energy storage cabinet provided in this specific embodiment, because the wires inside the base 1 are not conductive during installation, the wiring ports of the battery module 2 are not energized during stacking or disassembly, making the installation and disassembly process safe and reliable. That is, this application adopts a safe power line connection scheme, ensuring high electrical safety and eliminating the risk of electric shock during stacking installation and maintenance. Simultaneously, the circuit breaker 3-1 of the battery management module 3 is always open during installation, and the wires inside the base 1 are not conductive, so the ports of the quick-connect modules are not energized during stacking, ensuring safe and reliable installation. Therefore, the safety of personnel assembling and disassembling the energy storage cabinet is improved.

[0084] This application moves the battery management module 3 from the top layer to a lower side position on the energy storage cabinet. During the installation process, the height of the battery management module 3 remains constant and does not increase with the stacking height. The moderate height of the battery management module 3 facilitates installation, wiring, and subsequent maintenance, and improves the safety of personnel operating the energy storage cabinet.

The first handle 2-2 and the second handle 1-1 can be fastened to the lower housing 2-5 or the top cover 4 by threaded fasteners. Specifically, the threaded fasteners can be the mounting holes 2-10. This application integrates the limiting and fastening functions of the first handle 2-2, the second handle 1-1, the first limiting groove, and the second limiting groove, as well as the locking of the threaded fasteners. This allows the first handle 2-2 and the second handle 1-1 to integrate the dual functions of limiting and fastening, eliminating the need for additional handles and saving space and cost.
