Description

Technical Field

[0001] This utility model relates to the field of industrial and commercial energy storage, and in particular to an outdoor storage cabinet for industrial and commercial use. Background Technology

[0002] Commercial and industrial outdoor energy storage cabinets are important components for ensuring commercial and industrial energy storage. Existing commercial and industrial outdoor energy storage cabinets form battery packs through battery modules, and then install the battery packs into the battery compartment. The electrical compartment includes a high-voltage box, PCS and liquid cooling unit, etc. The components are connected by various independent plugs and pipelines, which results in high cost. Therefore, the size and weight are large, resulting in low energy density. Utility Model Content

[0003] The purpose of this utility model is to provide an outdoor storage cabinet for industrial and commercial use, which aims to solve the technical problem that the existing outdoor storage cabinets for industrial and commercial use are large in size and weight, resulting in low energy density.

[0004] Compared to existing technologies that involve assembling batteries into battery packs, with each battery pack having its own control circuitry and being installed in an energy storage cabinet, this application directly uses batteries to form battery modules. These modules are then directly connected to a liquid cooling unit and installed in the cabinet, eliminating the intermediate steps of forming battery packs and the need for control circuitry for each battery pack. This saves both space and cost, resulting in significant commercial value.

[0005] This application provides a commercial and industrial outdoor storage locker, including:

[0006] The battery compartment includes a first cabinet for installing battery modules;

[0007] The electrical compartment includes a second cabinet with an external interface. Inside the second cabinet are an energy storage converter and a liquid cooling unit. The energy storage converter is electrically connected to the battery module through the external interface, and the liquid cooling unit is connected to the battery module through the external interface. The liquid cooling unit is used to cool the battery module. The first cabinet is connected to the second cabinet.

[0008] The lower part of the first cabinet is equipped with a plug-in panel, and the upper part of the second cabinet is equipped with an external interface, which faces the plug-in panel. The plug-in panel allows for better external control, while the external interface centralizes the piping of the second cabinet.

[0009] The battery modules are connected in series via a busbar. A high-voltage component is located at the bottom of the first cabinet. The plug-in panel has a first high-voltage interface and a second high-voltage interface. The busbar is electrically connected to the first and second high-voltage interfaces respectively via the high-voltage component. This series connection increases the voltage to achieve high-voltage input and output.

[0010] The battery module is connected to the liquid cooling pipe. The plug-in panel has a first coolant interface and a second coolant interface. The liquid cooling pipe is connected to the liquid cooling unit through the first coolant interface, the second coolant interface, and an external interface. The battery module is in contact with the coolant pipe, and the coolant pipe is connected to the coolant unit.

[0011] The plug-in panel is equipped with a low-voltage communication interface, and the BMS installed in the first cabinet is electrically connected to the low-voltage communication interface. The BMS communicates with the outside world through the low-voltage communication interface to realize the transmission of internal and external signals.

[0012] The plug-in panel is equipped with a fire extinguishing interface for active fire suppression. The interface can be connected to inert gas.

[0013] The plug-in panel is equipped with a main switch disconnect device for circuit safety isolation. The main switch can disconnect the entire cabinet circuit.

[0014] The first cabinet includes a rear door panel, a front door panel, and a maintenance window. The rear door panel and the front door panel are installed in the first cabinet, and the maintenance window is installed in the front door panel. The maintenance window facilitates maintenance work.

[0015] The battery compartment is a sealed cavity formed by the front door panel, rear door panel, and maintenance window. It is also waterproof in special circumstances to prevent internal components from being damaged by moisture.

[0016] The first cabinet is equipped with an explosion-proof device and a hoisting mechanism. The explosion-proof device is installed on the front door panel, and the hoisting mechanism is installed on the first cabinet. The explosion-proof device is installed to achieve the functions of venting and explosion prevention. The hoisting mechanism facilitates the hoisting and installation of the cabinet.

[0017] The beneficial effects of the commercial and industrial energy storage cabinet provided by this utility model are: ① Increased energy density of the entire energy storage cabinet. Because the energy storage cabinet of the same size can accommodate more battery cells by reducing the number of structural components such as the outer shell, the weight of the entire cabinet is reduced. Energy density is the ratio of energy to mass; as energy increases and mass decreases, energy density increases. ② Reduced assembly and testing steps at the battery pack level, shortening the production process. ③ Elimination of the outer shell obstruction allows the battery modules to directly contact the cabinet's cold plate. The heat transfer path is shortened, the temperature difference is reduced, and the temperature distribution inside the battery compartment is more uniform. Attached Figure Description

[0035] Please refer to Figure 1-5 The following describes the industrial and commercial storage cabinet in the embodiments of this utility model.

[0036] Of particular note is that this application solves a problem that people have not been able to solve for a long time, has excellent practical effects, and has also achieved great commercial success.

[0037] Please refer to Figure 1-5 This application provides an industrial and commercial storage cabinet, including a first cabinet 101, which is used to install a battery module 107.
