Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage cabinets, and in particular relates to an outdoor energy storage cabinet. Background Art

[0002] Energy storage cabinet is a device specially designed to store electric energy. Its core components include battery pack, inverter (or converter), control chip, etc. The main function of energy storage cabinet is to store electric energy when the power supply is sufficient, and then release the electric energy when the power demand is peak or the power is insufficient. This kind of equipment has become a key component of modern energy system due to its high energy density, fast response time and long life.

[0003] The energy storage outdoor cabinet is a type of energy storage cabinet, which is mainly used in outdoor environments. When a fire occurs inside the energy storage outdoor cabinet, the fire-fighting system inside the energy storage outdoor cabinet can only spray to extinguish the fire after the battery cell thermally runs away. Once the battery cell thermally runs away and catches fire, the fire-fighting system can only temporarily extinguish the fire. After the concentration of the agent decreases over time, the battery cell will reignite. The significance of firefighting is only to buy time for the transfer of personnel and property, and it cannot fundamentally solve the problem. Summary of the invention

[0004] The present invention overcomes the deficiencies of the prior art and provides an outdoor energy storage cabinet to solve the problems existing in the prior art.

[0005] To achieve the above object, the technical solution adopted by the present invention is: an outdoor energy storage cabinet, comprising a cabinet body, wherein a plurality of layered cavities are provided in the cabinet body, and battery packs are loaded in the layered cavities;

[0006] An exhaust pipeline is located in the cabinet and connects the interior of the cabinet with the outside. A plurality of pressure relief valves are arranged on the exhaust pipeline. The pressure relief valves are located in the layered cavity and are connected to the exhaust pipeline to discharge the gas in the layered cavity.

[0007] In a preferred embodiment of the present invention, a plurality of detectors are arranged in the cabinet to monitor the gas conditions in the layered cavity.

[0008] In a preferred embodiment of the present invention, there are multiple detectors, which are evenly distributed in the layered cavity, and the detectors are gas detectors.

[0009] In a preferred embodiment of the present invention, the exhaust pipeline is located in the cabinet and is vertically arranged, and the pressure relief valves are evenly distributed on the exhaust pipeline.

[0010] In a preferred embodiment of the present invention, one end of the exhaust pipeline is a normally closed air inlet, and the other end is an air outlet.

[0011] In a preferred embodiment of the present invention, an exhaust fan is provided at the air outlet of the exhaust pipeline, and after the exhaust fan is started, the gas in the layered cavity is discharged through the exhaust pipeline.

[0012] In a preferred embodiment of the present invention, a protective cover is provided on the cabinet, and the protective cover shields and protects the exhaust fan.

[0013] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0014] 1. The energy storage outdoor cabinet of the present invention can quickly discharge the combustible gas in the outdoor cabinet after the battery cell has thermal runaway, effectively reducing the concentration of combustible gas in the outdoor cabinet, thereby avoiding the re-ignition of the battery cell in the cabinet, and fundamentally solving the fire protection problem of thermal runaway of the battery cell;

[0015] 2.

[0023] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0024] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0025] The present embodiment provides an outdoor energy storage cabinet, which can quickly discharge the combustible gas in the cabinet body 10 after the battery cell thermal runaway occurs, effectively reducing the concentration of combustible gas in the cabinet body 10, thereby avoiding the battery cell in the cabinet body 10 from re-igniting, and can fundamentally solve the fire protection problem of thermal runaway of the battery cell.

[0026] Combination Figures 1 to 4 As shown, the energy storage outdoor cabinet of this embodiment includes a cabinet body 10 and an exhaust pipe 20. A battery pack 30 is loaded in the cabinet body 10. The battery cells in the battery pack 30 are prone to thermal runaway. Therefore, a detector 40 is provided in the cabinet body 10 to monitor the concentration of combustible gas in the cabinet body 10 in real time.

[0027] In this embodiment, a plurality of layered cavities 11 are provided in the cabinet 10, and the battery packs 30 are respectively located in the layered cavities 11. The battery packs 30 and the layered cavities 11 form an independent unit, and the detectors 40 are located in the layered cavities 11. Therefore, each detector 40 can perform gas monitoring for the layered cavity 11 where each battery pack 30 is located.

[0028] Specifically, the detector 40 of this embodiment is a gas detector 40 , which can effectively monitor the combustible gas in the layered cavity 11 , thereby being able to timely sense the concentration of the combustible gas in the layered cavity 11 .

[0029] Combination Figure 3 and Figure 4As shown, the exhaust pipe 20 of the present embodiment is located in the cabinet 10, connecting the inside of the cabinet 10 with the outside, and a plurality of pressure relief valves 21 are arranged on the exhaust pipe 20. The pressure relief valve 21 is located in the layered cavity 11, and the pressure relief valve 21 is connected to the exhaust pipe 20 to discharge the gas in the layered cavity 11. When the battery cell has thermal runaway and the detector 40 detects that the concentration of the combustible gas in the cabinet 10 exceeds the established standard, the pressure relief valve 21 on the exhaust pipe 20 will automatically open, and the pressure relief valve 21 will quickly discharge the combustible gas in each layered cavity 11 through the exhaust pipe 20 to reduce the concentration of the combustible gas in the cabinet 10, thereby effectively avoiding the re-ignition of the battery cell in the cabinet 10, and fundamentally solving the fire protection problem of thermal runaway of the battery cell.

[0030] In this embodiment, the exhaust pipe 20 is located in the cabinet 10 and is vertically arranged. The pressure relief valves 21 are evenly distributed on the exhaust pipe 20. One end of the exhaust pipe 20 is a normally closed air inlet, and the other end is an air outlet. The air inlet of this embodiment is in a normally closed state. When necessary, it can be opened to allow external air to enter the cabinet 10, which can also effectively reduce the concentration of combustible gases.

[0031] Furthermore, an exhaust fan 50 is provided at the air outlet of the exhaust duct 20. After the exhaust fan 50 is started, the gas in the layered cavity 11 is discharged through the exhaust duct 20. A protective cover 60 is provided on the cabinet 10, and the protective cover 60 shields and protects the exhaust fan 50. After the exhaust fan 50 is started, the combustible gas in the cabinet 10 can quickly pass through the exhaust duct 20, and the combustible gas is extracted by the exhaust fan 50.

[0032] In actual use of the energy storage outdoor cabinet of this embodiment, the battery pack 30 located in the cabinet 10 is prone to thermal runaway, and the exhaust pipe 20 arranged in the cabinet 10 can quickly discharge the combustible gas in the cabinet 10 to avoid the re-ignition of the battery cell.

[0033] In summary, the energy storage outdoor cabinet of the present embodiment can quickly discharge the combustible gas in the outdoor cabinet body 10 after the battery cell has thermal runaway, effectively reducing the concentration of combustible gas in the outdoor cabinet body 10, thereby avoiding the re-ignition of the battery cell in the cabinet body 10, and can fundamentally solve the fire protection problem of thermal runaway of the battery cell. The pressure relief valves 21 are distributed in the layered cavity 11, so each pressure relief valve 21 can independently discharge the combustible gas in the layered cavity 11, improve the discharge efficiency of the combustible gas, and effectively avoid the re-ignition in the cabinet body 10. In addition, the detector 40 is used to effectively monitor the gas in the layered cavity 11, which can effectively avoid the re-ignition caused by excessively high concentration of combustible gas.
