[0001] Priority information

[0002] This application claims priority and benefits to patent application No. 2025202256872, filed with the China National Intellectual Property Administration on February 12, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of energy storage equipment technology, and particularly relates to a processing system for an energy storage device and two types of energy storage devices. Background Technology

[0004] As energy storage devices are increasingly used in various sectors of society, their safety is receiving more and more attention from users. In scenarios such as energy storage, emergency power supply, and industrial production, the safe and stable operation of energy storage devices is directly related to system safety and personnel safety.

[0005] Modern society's reliance on energy storage devices is constantly increasing. If a safety hazard arises in these devices, it can easily trigger a chain reaction, leading to serious consequences such as fires. Therefore, continuously improving the safety of energy storage devices to ensure their safe and reliable operation under various conditions is of paramount importance. Summary of the Invention

[0006] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a processing system for energy storage devices and two types of energy storage devices, which can improve the gas filling stability and processing efficiency of energy storage devices, thereby enhancing the safety and service life of energy storage devices.

[0007] In a first aspect, this application provides a processing system for an energy storage device, the energy storage device comprising a housing and an energy storage module, the energy storage module being disposed within the housing, the housing having an air vent, and the processing system comprising:

[0008] A conveying mechanism for transporting the energy storage device;

[0009] An inflation mechanism is used to evacuate air from the inside of the housing and to fill the inside of the housing with target gas through the air port.

[0010] A sealing mechanism is used to seal the air port;

[0011] Control mechanism, the control mechanism being used for:

[0012] The conveying mechanism is controlled to transport the energy storage device to a preset processing position;

[0013] When the energy storage device reaches the preset processing position, the inflation mechanism is controlled to evacuate the inside of the housing through the air port, and after evacuation, the inflation mechanism is controlled to fill the inside of the housing with the target gas.

[0014] After the target gas is introduced, the sealing mechanism is controlled to seal the gas port.

[0015] Secondly, this application provides an energy storage device, including a housing, the housing forming an air inlet, the housing being connected to a gas storage component through the air inlet, and the gas storage component being configured to fill the housing with a target gas through the air inlet.

[0016] Thirdly, another energy storage device provided in this application includes:

[0017] A housing, the interior of which forms a sealed space;

[0018] An energy storage module, wherein the energy storage module is disposed inside the housing;

[0019] The target gas fills the interior of the casing;

[0020] An electrical connection interface is provided on the housing and connected to the energy storage module, through which the energy storage module supplies power to the outside.

[0021] This application provides a processing system for energy storage devices and two types of energy storage devices. A conveying mechanism stably transports the energy storage devices to a preset processing position, reducing manual handling, ensuring processing accuracy and consistency, and improving production efficiency. An inflation structure evacuates air from the inside of the energy storage device's casing and fills it with a target gas. A sealing mechanism then seals the air vents of the inflated energy storage device, ensuring the target gas fills the gap between the casing and the energy storage module. This sealing prevents target gas leakage and prevents oxygen from the air from re-entering the casing and contacting the energy storage module, thus extending the module's lifespan. Furthermore, in the event of thermal runaway triggering factors in the energy storage module, the target gas can prevent fires.

[0022] In this way, by automatically completing the process of adding target gas and sealing the gas port of the energy storage device through the control mechanism, the gas filling stability and processing efficiency of the energy storage device can be improved, thereby enhancing the safety and service life of the energy storage device.

[0046] Please see Figure 1 , Figure 1 This is a schematic diagram of the processing system 1000 for an energy storage device 100 provided in this application embodiment. The processing system 1000 will be described in detail below:

[0047] The energy storage device 100 includes a housing 10 and an energy storage module, and the processing system 1000 includes a conveying mechanism 200, an inflation mechanism 400, a sealing mechanism 600, and a control mechanism 700.

[0048] The shell 10 refers to an outer shell structure with a storage space, which can be used to house the energy storage module. The shell 10 has an air port 11, which facilitates the processing system 1000 to evacuate the inside of the shell 10 and fill it with the target gas, ensuring that the target gas is evenly distributed in the internal space of the shell 10.

[0049] In one alternative embodiment, the housing 10 may be made of metal or plastic.

[0050] The metals can include galvanized steel, stainless steel, aluminum alloys, aluminum-magnesium alloys, copper alloys, etc.

[0051] The metal casing 10 has high strength, strong impact and deformation resistance, and can effectively protect the internal energy storage module. It also has good thermal conductivity, which is conducive to heat dissipation and can prevent heat accumulation. At the same time, the metal casing 10 has good high temperature resistance, which can delay structural failure in the early stage of thermal runaway of the energy storage module. In addition, it has a long service life, is resistant to aging and corrosion, and is suitable for a variety of complex environments.

[0052] Plastics can include polypropylene (PP), polycarbonate (PC), and acrylonitrile butadiene styrene copolymer (ABS), etc.

[0053] The plastic casing 10 is lightweight, which can reduce the overall load of the energy storage device 100; it is also easy to process and mold, and complex casing structures can be customized; at the same time, the plastic casing 10 is low in cost, making it suitable for small and medium power energy storage devices 100; it also has good insulation, which can reduce the risk of electric shock, and strong resistance to chemical corrosion. Some plastic materials also have certain flame retardancy, making them suitable for dry operating environments.

[0054] Optionally, the material of the housing 10 may also include glass fiber reinforced resin, carbon fiber composite material, ceramic matrix composite material, etc., and this application embodiment does not limit this.

[0055] The energy storage module is an independent energy storage unit formed by combining multiple energy storage cells in series and / or parallel. The energy storage module can store and release electrical energy. The energy storage module is set inside the housing 10 and is physically protected by the housing 10, isolating the internal circuits from the external environment, reducing the risk of electric shock, short circuits, etc., while facilitating installation, transportation and system integration.

[0056] Optionally, the energy storage module may include lithium battery modules, lead-acid battery modules, sodium battery modules, nickel-metal hydride battery modules, etc., and this application embodiment does not limit this.

[0057] The conveying mechanism 200 is a component used to transport the energy storage device 100. The conveying mechanism 200 can reduce manual handling and improve production efficiency.

[0058] Optionally, the conveying mechanism 200 includes a conveying motor 210, a conveying support 220, and a conveyor belt 230. The conveyor belt 230 is located on the conveying support 220 and can move along a set direction (such as a first direction) driven by the conveying motor 210; the conveyor belt 230 carries the energy storage device 100 and moves the energy storage device 100 in the set direction at a set speed. In this way, manual handling can be reduced and processing efficiency can be improved.

[0059] The inflation mechanism 400 is a component used to evacuate the interior of the housing 10 through the air port 11 and to inject the target gas into the housing 10. After the inflation mechanism 400 is connected to the air port 11 of the housing 10, it can quickly extract the air from the interior of the housing 10 and quickly inject the target gas into the housing 10 after evacuation, which can improve production efficiency and extend the service life of the energy storage device 100.

[0060] In one alternative embodiment, the target gas includes an inert gas, and / or the target gas includes at least one of nitrogen, helium, argon, neon, krypton, xenon, radon, and fluoride insulating gases.

[0061] Helium, argon, neon, krypton, xenon, and radon are all inert gases. Inert gases, nitrogen, and fluoride insulating gases are all chemically stable and do not readily react with other substances. Filling the housing 10 of the energy storage device 100 with at least one of these inert gases, nitrogen, or fluoride insulating gases can isolate oxygen, reduce the oxidation and aging process of the energy storage module inside the housing 10, and lower the risk of combustion and explosion. It can also enhance the insulation performance inside the housing 10, prevent short circuits, maintain a clean environment inside the housing 10, ensure the stable operation of the energy storage module, and extend the service life of the energy storage module.

[0062] The sealing mechanism 600 is a component used to seal the air port 11 of the energy storage device 100. The sealing mechanism 600 can quickly seal the air port 11 of the energy storage device 100 after the target gas has been injected, preventing external dust, water vapor, and corrosive gases from entering, preventing leakage of insulating gas inside the casing 10, protecting the internal energy storage module, maintaining good sealing performance of the energy storage device 100, and improving production efficiency.

[0063] The control mechanism 700 is a component used to control the process of evacuating the energy storage device 100, adding the target gas, and sealing the gas port 11.

[0064] The control mechanism 700 is used to control the conveying mechanism 200 to transport the energy storage device 100 to the preset processing position;

[0065] The preset processing position is the designated position corresponding to the process of evacuating, adding target gas, and sealing the gas port 11 of the energy storage device 100. The conveying mechanism 200 sequentially transports each energy storage device 100 to the preset processing position, which facilitates the processing of the energy storage device 100 by each component of the processing system 1000, ensuring the processing accuracy and consistency of the energy storage device 100 and improving production efficiency.

[0066] When the energy storage device 100 reaches the preset processing position, the control mechanism 700 is also used to control the inflation mechanism 400 to evacuate the inside of the housing 10 through the air port 11, and after evacuation, control the inflation mechanism 400 to fill the housing 10 with the target gas; after filling with the target gas, the control mechanism 700 is also used to control the sealing mechanism 600 to seal the air port 11. By evacuating, impurities such as air and water vapor inside the housing 10 can be removed, preventing these impurities from reacting with the energy storage module in an oxidation reaction or causing a short circuit; filling with the target gas isolates oxygen, reduces aging, improves the fire and explosion safety of the energy storage module, and extends its service life.

[0067] In this way, by automatically completing the process of adding target gas and sealing the gas port 11 of the energy storage device 100 through the various components of the processing system 1000, the gas filling stability and processing efficiency of the energy storage device 100 can be improved, thereby enhancing the safety and service life of the energy storage device 100.

[0068] Please see Figure 1 , Figure 2 and Figure 3 In one optional embodiment, the inflation mechanism 400 includes a connector 410, a connecting pipe 420, an air extraction component 430, and an air storage component 440. One end of the connector 410 is connected to the air port 11, and the other end is connected to the air extraction component 430 and the air storage component 440 respectively through the connecting pipe 420. The air extraction component 430 is used to extract air, and the air storage component 440 is used to fill in the target gas.

[0069] The control mechanism 700 is used to control the air extraction component 430 to extract air when the energy storage device 100 reaches the preset processing position, so that the inside of the housing 10 is in a negative pressure state, and to control the gas storage component 440 to fill the inside of the housing 10 with the target gas when the inside of the housing 10 is in a negative pressure state.

[0070] The gas inside the housing 10 is sequentially extracted to the outside of the housing 10 through the air port 11, connector 410, and connecting pipe 420. The target gas stored in the gas storage assembly 440 is injected into the negative pressure interior of the housing 10 through the connecting pipe 420. In this way, impurities such as air and water vapor inside the housing 10 can be basically removed, reducing the probability of these impurities reacting with the energy storage module to cause oxidation or short circuits. This method is easy to implement and thus extends the service life of the energy storage module.

[0071] Optionally, when the energy storage device 100 reaches the preset processing position, the control mechanism 700 controls the vacuum pumping assembly 430 to extract the gas inside the housing 10, so that the inside of the housing 10 is in a vacuum state. While the inside of the housing 10 is in a vacuum state, the control mechanism 700 controls the gas storage assembly 440 to fill the inside of the housing 10 with the target gas. In a vacuum state, air, water vapor, and other impurities inside the housing 10 can be completely extracted, preventing these impurities from reacting with the energy storage module in an oxidation reaction or causing a short circuit, thus improving the service life of the energy storage module.

[0072] Please see Figure 1 In an optional embodiment, the inflation mechanism 400 further includes an air pressure detection device 450, which is used to detect the air pressure inside the housing 10. The control mechanism 700 is also used to determine that the inside of the housing 10 is in a negative pressure state when the air pressure is less than a first preset air pressure threshold.

[0073] The first preset air pressure threshold is an empirical value.

[0074] The air pressure detection device 450 detects the air pressure inside the housing 10 during or after the air extraction process. If the air pressure is lower than the first preset air pressure threshold, it is determined that the inside of the housing 10 is in a negative pressure state. If the air pressure is greater than or equal to the first preset air pressure threshold, it is determined that the inside of the housing 10 is not in a negative pressure state, and the control mechanism 700 continues to control the air extraction component 430 to extract air from the housing 10.

[0075] In this way, a standard can be clearly defined to determine whether the inside of the casing 10 is under negative pressure, ensuring the processing accuracy and consistency of the energy storage device 100.

[0076] In an optional embodiment, the control mechanism 700 is further configured to:

[0077] When the inside of the housing 10 is under negative pressure, the air extraction component 430 is controlled to stop extracting air.

[0078] Based on the air pressure within the first preset time after the air extraction stops, the air tightness of the housing 10 is tested to obtain the air tightness test result, which includes whether the housing 10 leaks air.

[0079] If the housing 10 is not leaking, the gas storage assembly 440 is controlled to fill the housing 10 with the target gas.

[0080] The first preset duration is a value set based on experience. For example, 30 seconds, 1 minute, 2 minutes, etc.

[0081] An airtightness test is performed on the casing 10 after internal air extraction to obtain the test results. The airtightness of the casing 10 is then determined based on these results. If the casing 10 leaks air, the airtightness fails to meet the standard; if it does not leak air, the airtightness meets the standard. Once the casing 10 is airtight (i.e., meets the airtightness standard), the target gas is added inside. This ensures that the target gas will not leak out, and that external moisture, dust, etc., will not enter the casing 10, thus guaranteeing the safety and service life of the energy storage device 100.

[0082] In one optional embodiment, the airtightness of the housing 10 is tested based on the air pressure within a first preset time period after the pumping stops, to obtain the airtightness test result, including:

[0083] If the increase in air pressure reaches the second preset air pressure threshold within the first preset time period, then the housing 10 is determined to be leaking air.

[0084] If the increase in air pressure does not reach the second preset air pressure threshold within the first preset time period, it is determined that the housing 10 is not leaking air.

[0085] The second preset air pressure threshold is an empirical value.

[0086] The air pressure detection device 450 detects the first air pressure value at the moment when the air pumping stops, and the air pressure value within a first preset time after the air pumping stops. The maximum value among the detected air pressure values ​​within the first preset time after the air pumping stops is the second air pressure value. The second air pressure value minus the first air pressure value is the air pressure increment. Based on the relationship between the air pressure increment and the second preset air pressure threshold, it is determined whether the housing 10 is leaking air.

[0087] This ensures that the airtightness of the housing 10 meets the standards, prevents external debris from entering the housing 10, and avoids leakage of the target gas or electrolyte from the leaked energy storage module, thereby enhancing the safety, stability, and service life of the energy storage device 100.

[0088] In one optional embodiment, controlling the inflation mechanism 400 to inflate the housing 10 with the target gas includes:

[0089] The inflation mechanism 400 is controlled to inflate the target gas into the housing 10 so that the gas pressure inside the housing 10 is greater than the external atmospheric pressure.

[0090] During the process of adding the target gas into the housing 10, the gas pressure detection device 450 detects the gas pressure value inside the housing 10 in real time. If the gas pressure value inside the housing 10 is greater than the external atmospheric pressure (such as the difference between the gas pressure value inside the housing 10 and the external atmospheric pressure being greater than a preset difference threshold, where the preset difference threshold is a positive value and is an empirical value, etc.), the inflation is determined to be complete and inflation is stopped.

[0091] In this way, the positive pressure can effectively prevent external air, water vapor and other substances from entering the interior of the housing 10, avoiding oxidation, moisture or short circuit of the energy storage module; even if a fault (such as external impact) causes a small gap in the housing 10, the target gas inside will leak out first, reducing the entry of external impurities into the interior of the housing 10, thereby improving the safety of the energy storage device 100 and extending the service life of the energy storage device 100.

[0092] Please see Figure 1 , Figure 2 and Figure 3 In an optional embodiment, a first driving mechanism 800 is further included. The first driving mechanism 800 is used to drive the inflation mechanism 400 to move. The control mechanism 700 is also used to obtain the model of the energy storage device 100 and control the first driving mechanism 800 to drive the inflation mechanism 400 to move based on the first movement parameter corresponding to the model of the energy storage device 100, so that the inflation mechanism 400 is connected to the air port 11.

[0093] The first movement parameter is a physical quantity used to control the position, direction of movement, and speed of movement of the inflatable structure as they change over time.

[0094] Specifically, based on the first movement parameters corresponding to the model of the energy storage device 100, the first drive mechanism 800 is controlled to drive the inflation mechanism 400 to move and connect with the air port 11. This ensures that the position of the inflation mechanism 400 after movement is aligned with the air port 11 of the housing 10 of the current model of the energy storage device 100, adapting to the positions of the air ports 11 of different models of energy storage devices 100, avoiding misalignment between the inflation mechanism 400 and the air port 11, and ensuring the accuracy and consistency of the subsequent air extraction and inflation processes of the current model of the energy storage device 100.

[0095] In an alternative embodiment, the sealing mechanism 600 seals the vent 11 using a heat-fusion sealing process.

[0096] Specifically, the sealing mechanism 600 melts the sealing material (such as hot melt adhesive, plastic, etc.) by heating. The melted sealing material adheres to the air port 11 of the housing 10. After the sealing material cools and solidifies, it forms a sealing structure, thereby achieving a seal on the housing 10.

[0097] In this way, the housing 10 after the sealed air inlet 11 can achieve a sealing effect such as leak prevention and moisture prevention, thereby improving the safety and stability of the energy storage device 100.

[0098] Please see Figure 2 , Figure 4 and Figure 6 In one optional embodiment, the edge of the air port 11 forms an annular protrusion 12. The system also includes a second drive mechanism 850, which is used to drive the sealing mechanism 600 to move. The control mechanism 700 is also used to obtain the model of the energy storage device 100 and, based on the second movement parameters corresponding to the model of the energy storage device 100, control the second drive mechanism 850 to drive the sealing mechanism 600 to move so that the sealing mechanism 600 is aligned with the annular protrusion 12.

[0099] The second movement parameter is a physical quantity used to control the changes in the position, direction of movement, and speed of the sealing structure over time.

[0100] Specifically, based on the second movement parameters corresponding to the model of the energy storage device 100, the second drive mechanism 850 is controlled to drive the sealing mechanism 600 to move and connect with the annular boss 12 on the edge of the air port 11. This ensures that the position of the sealing mechanism 600 after movement is aligned with the annular boss 12 on the edge of the air port 11 of the housing 10 of the current model of the energy storage device 100, adapting to the edge of the air port 11 of different models of energy storage devices 100, avoiding misalignment between the inflation mechanism 400 and the annular boss 12 of the air port 11, and ensuring the accuracy and consistency of the subsequent sealing process of the current model of the energy storage device 100.

[0101] Please see Figure 2 , Figure 4 and Figure 6 In one alternative embodiment, an annular boss 12 is formed at the edge of the air vent 11, and a sealing mechanism 600 is used to seal the annular boss 12, the material of which includes plastic.

[0102] Specifically, the edge of the air port 11 of the housing 10 forms an annular boss 12, which can enhance the structural strength of the air port 11, prevent the air port 11 from deforming under force, and provide a reference for the sealing mechanism 600 to ensure that the sealing mechanism 600 is aligned with the annular boss 12; moreover, the annular boss 12 can increase the contact area with the sealing mechanism 600, increase the sealing area, improve the fit of the sealing surface, and enhance the sealing effect.

[0103] Plastics (such as PP, PC, ABS, etc.) have a certain degree of elasticity and are easy to deform under pressure, which can further fill the sealing gap and improve the sealing adaptability. At the same time, plastics are lightweight, resistant to aging and low in cost, which can reduce the overall weight of the energy storage device 100 and extend the service life of the energy storage device 100.

[0104] Alternatively, the material of the annular boss 12 can also be stainless steel, rubber, composite material, etc., and this application embodiment does not limit this.

[0105] Please see Figure 1 , Figure 2 and Figure 3 In one optional embodiment, a positioning mechanism 900 is further included, which is used to position the energy storage device 100 so that the energy storage device 100 is located at a preset processing position.

[0106] The preset processing location is a fixed area where the energy storage device 100 to be processed needs to be precisely placed, based on experience.

[0107] Optionally, different models of the energy storage device 100 correspond to different preset processing positions.

[0108] Specifically, by positioning the energy storage device 100 to be processed at the preset processing position through the positioning mechanism 900, it can be ensured that the various component structures of the processing system 1000 are processed according to the precise coordinates corresponding to the preset processing position, thereby ensuring the processing accuracy of the energy storage device 100 in terms of gas extraction, target gas injection and heat fusion sealing, avoiding dimensional deviations, and improving the production consistency and efficiency of the energy storage device 100.

[0109] Please see Figure 2 and Figure 5 In one optional embodiment, the positioning mechanism 900 includes a first limiting component 910 and a second limiting component 920. The first limiting component 910 is used to limit the energy storage device 100 in a first direction, and the second limiting component 920 is used to limit the energy storage device 100 in a second direction. The first direction and the second direction are perpendicular.

[0110] Specifically, the first direction is the X-direction, and the second direction is the Y-direction. The first and second directions are perpendicular, allowing the positioning mechanism 900 to precisely constrain the energy storage device 100 from two vertical dimensions, ensuring that the energy storage device 100's position on the plane of the conveying mechanism 200 is unique and stable. When evacuating, injecting the target gas, and sealing the energy storage device 100, displacement of the energy storage device 100 due to vibration or transport deviations of the conveying mechanism 200 can be avoided, improving processing accuracy and consistency, and increasing processing efficiency of the energy storage device 100.

[0111] Please see Figure 1 , Figure 2 and Figure 3In an optional embodiment, the first direction parallel to the conveying direction of the conveying mechanism 200, the first limiting component 910 includes an in-situ sensor 913, a first sub-limiting member 911, a second sub-limiting member 912, and a first driving member 914. The conveying mechanism 200 includes opposing first ends 221 and second ends 222, which are distributed along a second direction. The first sub-limiting member 911 is disposed at the first end 221, and the distance between the first sub-limiting member 911 and the second end 222 is less than the dimension of the energy storage device 100 along the second direction. The in-situ sensor 913 is used to detect whether the energy storage device 100 has reached the position of the first sub-limiting member 911. The first driving member 914 is used to drive the second sub-limiting member 912 to move. The control mechanism 700 is further used for:

[0112] When the energy storage device 100 is detected to have reached the position of the first sub-limiting member 911, the first driving member 914 is controlled to drive the second sub-limiting member 912 to move a first distance towards the second end 222 along the second direction, so that the distance between the second sub-limiting member 912 and the second end 222 is less than the size of the energy storage device 100 along the second direction.

[0113] The first driving member 914 drives the second sub-limiting member 912 to move along the first direction toward the first sub-limiting member 911, so that the first sub-limiting member 911 and the second sub-limiting member 912 clamp the energy storage device 100.

[0114] The first distance is an empirical value.

[0115] Specifically, firstly, the first driving member 914 is controlled to drive the second sub-limiting member 912 to move a first distance along the second direction toward the second end 222, and then the first driving member 914 is controlled to drive the second sub-limiting member 912 to move along the first direction toward the first sub-limiting member 911.

[0116] Since the distance between the first sub-limiting member 911 and the second end 222 is smaller than the size of the energy storage device 100 along the second direction, when the energy storage device 100 conveyed by the conveying mechanism 200 reaches the position of the first sub-limiting member 911, the energy storage device 100 is blocked by the first sub-limiting member 911 and cannot continue to move in the first direction under the action of the conveying mechanism 200.

[0117] When the energy storage device 100 is blocked by the first sub-limiting member 911 and the second sub-limiting member 912 moves, since the distance between the second sub-limiting member 912 and the second end 222 is less than the size of the energy storage device 100 along the second direction, the second sub-limiting member 912 can contact the energy storage device 100 after moving in the first direction and clamp the energy storage device 100 with the first sub-limiting member 911.

[0118] In this way, it can be ensured that the position of the energy storage device 100 in the first direction on the plane of the transmission mechanism 200 is unique and stable, thereby ensuring the processing accuracy and consistency of the energy storage device 100.

[0119] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In one optional embodiment, the first direction parallel conveying mechanism 200 conveys in a specific direction. The second limiting component 920 includes a third sub-limiting member 921, a fourth sub-limiting member 922, and a second driving member 923. The second driving member 923 is used to drive the third sub-limiting member 921 closer to or away from the fourth sub-limiting member 922. The control mechanism 700 is further used for:

[0120] When the energy storage device 100 is detected to have reached the position of the first sub-limiting member 911 of the first limiting component 910, the second driving member 923 is controlled to drive the third sub-limiting member 921 to move closer to the fourth sub-limiting member 922, so that the third sub-limiting member 921 and the fourth sub-limiting member 922 clamp the energy storage device 100.

[0121] In this way, it can be ensured that the position of the energy storage device 100 in the second direction on the plane of the transmission mechanism 200 is unique and stable, thereby ensuring the processing accuracy and consistency of the energy storage device 100.

[0122] In an optional embodiment, when the energy storage device 100 is detected to have reached the position of the first sub-limiting member 911, the process of controlling the first driving member 914 to drive the second sub-limiting member 912 to move and the process of controlling the second driving member 923 to drive the third sub-limiting member 921 to move closer to the fourth sub-limiting member 922 can be performed simultaneously or sequentially. This application embodiment does not limit this.

[0123] Please see Figure 2 and Figure 3 In one alternative embodiment, both the third sub-limiter 921 and the fourth sub-limiter 922 include a plurality of spaced rollers 924.

[0124] Specifically, during the process of the control component controlling the second driving member 923 to drive the third sub-limiting member 921 closer to the fourth sub-limiting member 922, the energy storage device 100 contacts the roller 924 and moves in the second direction. Thus, through rolling contact, friction between the roller and the energy storage device 100 during the second-direction limiting process can be reduced, preventing scratches on the surface of the energy storage device 100. Furthermore, the contact of multiple rollers 924 with the energy storage device 100 can stably constrain the position of the energy storage device 100, preventing displacement and thereby improving the processing efficiency of the energy storage device 100.

[0125] Optionally, the positioning mechanism 900 further includes a third driving member 915, which drives the first sub-limiting member 911 to move along the second direction, such that the distance between the first sub-limiting member 911 and the second end 222 is less than, equal to or greater than, the dimension of the energy storage device 100 along the second direction.

[0126] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In an optional embodiment, the control mechanism 700 is further configured to:

[0127] After sealing the air vent 11, the first limiting component 910 and the second limiting component 920 are moved to release the limiting of the energy storage device 100 in the first and second directions.

[0128] The energy storage device 100 proceeds to the next unsealed gas port 11 by pumping out gas, injecting the target gas, and sealing the gas port 11.

[0129] Specifically, after sealing the vent 11 of the current energy storage device 100, the limiting mechanism for the energy storage device 100 is engaged. This involves a first driving member 914 driving a second sub-limiting member 912 to move, a second driving member 923 driving a third sub-limiting member 921 to move, and a third driving member 915 driving a first sub-limiting member 911 to move. This allows the energy storage device 100 to leave the processing area under the action of the conveying mechanism 200, making room for a new energy storage device 100 to be processed, and ensuring that the positioning mechanism 900 can quickly reset and accurately constrain the next energy storage device 100.

[0130] This reduces the time between processes, maintains the smoothness of the processing, and improves processing efficiency and equipment utilization.

[0131] Please see Figures 8 to 10 This application provides an energy storage device 100, which includes a housing 10, a gas port 11 formed in the housing 10, and a gas storage component 440 connected to the housing 10 through the gas port 11. The gas storage component 440 is configured to fill the housing 10 with a target gas through the gas port 11.

[0132] Specifically, the energy storage device 100 can be used to release electrical energy to power a load. The energy storage device 100 can be an emergency power supply, outdoor power supply, start-stop power supply, etc.

[0133] The energy storage device 100 includes an energy storage module 30 and a housing 10. The energy storage module 30 is disposed inside the housing 10. The housing 10 provides support for the energy storage module 30 and provides collision protection.

[0134] In some embodiments, the energy storage module 30 includes a rechargeable battery or a supercapacitor, wherein the rechargeable battery includes at least one of a sodium battery or a lithium battery. For example, the energy storage module 30 can be at least one of a lithium cobalt oxide battery, a lithium manganese oxide battery, a lithium iron phosphate battery, or a nickel-cobalt-manganese lithium battery. In the event of an overcharge or other abnormality in the energy storage module 30, the rapidly generated large amount of heat and gas may lead to deflagration and / or thermal runaway, causing equipment damage and endangering user safety.

[0135] The energy storage device 100 of this application embodiment has an air port 11 formed on its housing 10. The housing 10 can be connected to a gas storage assembly 440 through the air port 11, so that the gas storage assembly 440 can fill the housing 10 with a target gas.

[0136] In some embodiments, the target gas includes an inert gas, and / or, the target gas includes at least one of nitrogen, helium, argon, neon, krypton, xenon, radon, and fluoride insulating gases. When a high concentration of the target gas is present inside the energy storage device 100, the oxygen content is relatively low, which can reduce the possibility of thermal runaway or deflagration of the energy storage module 30 inside the energy storage device 100. The gas storage assembly 440 is a component for storing the target gas, including gas cylinders, gas tanks, gas bags, etc.

[0137] The embodiments of this application provide safety protection from the perspective of overcharging. By filling the housing 10 with a target gas, the energy storage module 30 can be placed in a non-flammable target gas to isolate oxygen, so that the deflagration caused by overcharging of the energy storage module 30 can be quickly extinguished, reducing the harm caused by deflagration or thermal runaway of the energy storage module 30.

[0138] In addition, keeping the energy storage module 30 in a low-oxygen environment for a long time helps to extend the service life of the energy storage module 30.

[0139] In one embodiment, the gas storage assembly 440 is a nitrogen tank. The air inlet 11 is located on one side of the housing 10 of the energy storage device 100, and the nitrogen tank can fill the housing 10 with nitrogen through the air inlet 11.

[0140] In some embodiments, the pressure of the target gas introduced into the housing 10 ranges from 0.05 MPa to 1.2 MPa. That is, the pressure of the target gas introduced into the housing 10 can be 0.05 MPa, 0.1 MPa, 0.3 MPa, 0.5 MPa, 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.2 MPa, etc. Preferably, the pressure of the target gas introduced into the housing 10 ranges from [0.1 MPa, 1.0 MPa].

[0141] In one embodiment, the pressure of the target gas injected into the housing 10 ranges from [0.5 MPa, 0.8 MPa].

[0142] In this way, a non-flammable target gas is introduced into the housing 10 through the gas storage component 440, so that the housing 10 is continuously filled with the target gas. When the battery inside the housing 10 experiences thermal runaway, it cannot continue to burn due to lack of oxygen, and the flame can be quickly extinguished, thereby avoiding further serious consequences after the battery thermal runaway.

[0143] Please see Figure 8 and Figure 9 In some embodiments, the energy storage device 100 includes a gas valve 50 disposed at the gas port 11, and the gas storage assembly 440 is connected to the gas valve 50 via a detachable gas pipe 500 to charge the housing 10 with target gas through the gas pipe 500.

[0144] Specifically, the gas valve 50 is located at the gas port 11 of the housing 10 of the energy storage device 100. The gas storage assembly 440 can be connected to the gas valve 50 via a detachable gas pipe 500, thereby achieving connection with the housing 10. When the gas storage assembly 440 is connected to the gas valve 50 via the gas pipe 500, the gas storage assembly 440 charges the housing 10 with the target gas through the gas pipe 500.

[0145] The gas valve 50 can be a one-way valve, and the gas flow direction is from the outside of the housing 10 to the inside of the housing 10. The detachable gas pipe 500 means that the gas pipe 500 can be separated from the gas valve 50 and the gas storage component 440. In this case, the gas valve 50 prevents the gas inside the gas storage component 440 from flowing out. Alternatively, the gas pipe 500 can be connected at both ends to the gas valve 50 and the gas storage component 440 respectively, so that the gas storage component 440 can be filled with gas into the housing 10 through the gas pipe 500 and the gas valve 50. The detachable gas pipe 500 allows for easy filling with nitrogen to maintain the nitrogen concentration inside the housing 10 when there is a small amount of leakage inside the energy storage device 100 housing 10.

[0146] In some embodiments, the volume of the gas storage component 440 includes 40L, 50L, 60L, 70L, 80L, etc., which can be set according to actual needs.

[0147] In one embodiment, the energy storage device 100 is an emergency power source, the target gas is nitrogen, and the gas storage component 440 is a nitrogen cylinder. A one-way valve is matched to the nitrogen cylinder. If the energy storage device 100 experiences a small leak, it needs to be refilled. This can be done by connecting the nitrogen cylinder to the one-way valve on the emergency power source housing 10 via a gas hose 500, and then refilling the emergency power source housing 10 with nitrogen through the gas hose 500.

[0148] Thus, by connecting the gas valve 50 to the detachable gas pipe 500, the gas storage assembly 440 can be inflated into the housing 10. The gas valve 50 also prevents the gas inside the housing 10 from leaking to the outside when not needed, ensuring the airtightness of the housing 10.

[0149] Please see Figure 11 In some embodiments, the energy storage device 100 further includes at least one pressure relief valve 70, which is used to release gas inside the housing 10 when the gas pressure inside the housing 10 is greater than a preset gas pressure.

[0150] Specifically, when the energy storage module 30 malfunctions, it generates a large amount of heat and gas, causing an increase in the air pressure inside the housing 10 of the energy storage device 100. When the air pressure inside the housing 10 becomes too high, an explosion may occur due to excessive pressure.

[0151] The energy storage device 100 may include at least one pressure relief valve 70. The pressure relief valve 70 may be installed on the housing 10 of the energy storage device 100 and may connect the interior and exterior of the housing 10. When the gas pressure inside the housing 10 exceeds a preset pressure, the pressure relief valve 70 is activated, connecting the interior and exterior of the housing 10. At this time, due to the higher gas pressure inside the housing 10, the gas inside the housing 10 can be released to the outside of the energy storage device 100 through the pressure relief valve 70, thereby relieving pressure inside the energy storage device 100. The pressure relief valve 70 allows a large amount of gas to be discharged, preventing an explosion due to excessive pressure inside the housing 10, reducing the possibility of open flames, and preventing fires. Furthermore, it can protect people from shrapnel injuries from an explosion, providing a final line of defense.

[0152] The preset air pressure is the maximum pressure value that the pressure relief valve 70 can withstand, which can be determined according to the material of the pressure relief valve 70 and the size of the housing 10 of the energy storage device 100. For example, the preset air pressure ranges from 1 MPa to 5 MPa. That is to say, the preset air pressure can be 1.0 MPa, 1.1 MPa, 1.5 MPa, 2 MPa, 2.9 MPa, 3.5 MPa, 4.0 MPa, 4.5 MPa, 5 MPa, etc., without any restrictions.

[0153] In one embodiment, the preset air pressure ranges from 1 MPa to 1.0 MPa. In another embodiment, the preset air pressure ranges from 2 MPa to 5 MPa.

[0154] In another embodiment, the housing 10 includes a box body 13 and a cover 15 disposed opposite to the box, and a pressure relief valve 70 may be disposed on the cover 15. In one embodiment, see [reference needed]. Figure 11 The energy storage device 100 includes two pressure relief valves 70. The pressure relief valves 70 are located on the cover 15 of the energy storage device 100.

[0155] Furthermore, the vent valve is a one-way valve, and the allowed gas flow direction is from inside the housing 10 of the energy storage device 100 to outside the housing 10.

[0156] Thus, by setting the pressure relief valve 70, the gas inside the housing 10 can be released when the gas pressure inside the housing 10 is too high, thereby reducing the gas pressure inside the housing 10 and preventing the housing 10 from exploding due to excessive gas pressure.

[0157] Please see Figure 11 In some embodiments, a pressure relief valve 70 is disposed in the housing 10, and the pressure relief valve 70 includes a blocking member 71, which is tightly connected to the pressure relief valve 70.

[0158] Specifically, the shape of the blocking member 71 includes a cone shape, a piston shape, etc. In some embodiments, the material of the blocking member 71 includes rubber, PTFE (polytetrafluoroethylene), PU (polyurethane), etc. When the air pressure inside the housing 10 is less than or equal to the preset air pressure, the blocking member 71 is tightly connected to the pressure relief valve 70 to block the gas passage of the pressure relief valve 70 and block the flow of gas inside and outside the housing 10.

[0159] Thus, by including the pressure relief valve 70 with the blocking member 71, and with the blocking member 71 tightly connected to the pressure relief valve 70, the gas inside the housing 10 of the energy storage device 100 will not flow to the outside through the pressure relief valve 70 under normal conditions, and the external gas will not flow into the housing 10 through the pressure relief valve 70, thereby ensuring the target gas concentration inside the energy storage device 100 under normal conditions.

[0160] In some embodiments, when the air pressure inside the housing 10 is greater than a preset air pressure, the blocking member 71 separates from the pressure relief valve 70.

[0161] Specifically, when the air pressure inside the housing 10 is greater than the preset air pressure, the blocking member 71 separates from the pressure relief valve 70 under the pressure inside the housing 10, thus opening the gas passage inside the pressure relief valve 70. When the blocking member 71 separates from the pressure relief valve 70, the gas inside the energy storage device 100 is released to the outside to relieve pressure.

[0162] Thus, when the air pressure inside the housing 10 is greater than the preset air pressure, the blocking member 71 separates from the pressure relief valve 70, allowing the pressure relief valve 70 to release the gas inside the housing 10, thereby realizing the release of gas inside the energy storage device 100 when the air pressure inside the housing 10 is greater than the preset air pressure.

[0163] In some embodiments, the valve port size of the pressure relief valve 70 is smaller than a preset size, and the pressure relief valve 70 can generate a popping sound when it is in a depressurized state.

[0164] Specifically, the preset size is a pre-set value that can be set according to actual needs, and then a pressure relief valve 70 that meets the requirements can be selected based on the preset size. For pressure relief valves 70 with a valve port size smaller than the preset size, when the pressure relief valve 70 is in a pressure-relief state, a popping sound will be generated due to the rapid flow of gas at the valve port. The popping sound generated by the pressure relief valve 70 itself can alert the user to deal with the abnormality of the energy storage device 100 in time, or to take timely precautions, without the need for additional sound-generating devices such as buzzers, simplifying the structural design of the energy storage device 100 and contributing to the lightweight design of the energy storage device 100.

[0165] Therefore, by setting a vent valve with a smaller opening, the gas can produce a popping sound when it is discharged, which will create a sharp noise to remind the user to quickly cut off the power and evacuate.

[0166] Please see Figure 9 In some embodiments, the housing 10 includes a box body 13, a cover 15, and a sealing strip 17, with the box body 13 and the cover 15 being sealed together by the sealing strip 17.

[0167] Specifically, the box body 13 and the cover body 15 are arranged opposite each other, and a sealing strip 17 is provided between the box body 13 and the cover body 15 so that the box body 13 and the cover body 15 are sealed together by the sealing strip 17.

[0168] Thus, the sealed connection formed by the housing 13, the cover 15 and the sealing strip 17 allows the housing 10 to have high airtightness while facilitating the installation of internal components, thereby providing additional waterproof performance for the energy storage device 100 and improving the safety protection level of the energy storage device 100.

[0169] Please see Figure 12 In some embodiments, the housing 13 forms at least one accommodating cavity 131, which is configured to accommodate the energy storage module 30.

[0170] Specifically, the energy storage module 30 includes at least one battery cell. The housing 13 forms at least one battery cell interlayer, each forming a receiving cavity 131. Each battery cell can be disposed within one receiving cavity 131. Forming the battery cell interlayer within the housing 13 facilitates the installation of the battery cell into the energy storage module 30 before closing the cover 15 and housing 13, thus facilitating the installation of the energy storage device 100. Furthermore, the housing 13 provides protection for the energy storage module 30, preventing it from being impacted.

[0171] In one embodiment, the energy storage device 100 includes three cell sandwiches, each containing one cell.

[0172] Thus, the accommodating cavity 131 formed by the housing 13 allows the housing 13 and cover 15 to be closed after the energy storage module 30 is installed into the accommodating cavity 131, which facilitates the installation of the energy storage module 30.

[0173] In some embodiments, the housing 13 and the cover 15 are made of PC (polycarbonate), ABC, plastic and / or nylon.

[0174] Specifically, considering the pressure-bearing capacity of the energy storage device 100, materials such as PC, ABC, plastic, and / or nylon can be used. The housing 13 and / or cover 15 are manufactured to meet pressure-bearing requirements while satisfying cost constraints, enabling the housing 13 and cover 15 to withstand certain external pressure or impacts, protecting the internal energy storage module 30 from easy damage. ABC material includes plastic alloys, plastic blends, and filled reinforced composite plastics. Those skilled in the art can also choose other suitable materials to manufacture the housing 13 or cover 15 according to requirements; no limitations are imposed here.

[0175] Furthermore, the materials of the box body 13 and the cover body 15 can be different or the same, and there are no restrictions here.

[0176] In one embodiment, both the housing 13 and the cover 15 are made of PC and ABC materials, respectively.

[0177] Thus, by using PC, ABC, plastic and / or nylon materials to make the box body 13 and the cover 15, the pressure resistance requirements of the box body 13 and the cover 15 can be met.

[0178] In some embodiments, the energy storage device 100 further includes an electrical connection interface, which includes at least one or more of a USB interface, an AV jack, a DC interface, and a cigarette lighter jack. The electrical connection interface is connected to the energy storage module 30 of the energy storage device 100.

[0179] Specifically, the electrical connection interface can be used to connect external devices to supply power to them. The electrical connection interface can be one or more of the following: USB interface, AV (composite video) jack, DC (direct current) interface, or cigarette lighter jack. Users can connect external devices to the electrical connection interface via specific connecting cables to obtain power from the energy storage device 100, according to their own needs.

[0180] In one embodiment, a user can connect the power device and the energy storage device 100 via a USB interface and a USB cable to use the energy storage device 100 to charge or supply power to the power device.

[0181] In this way, external devices can be connected through the electrical connection interface to enable the energy storage module 30 to supply power to external devices. Furthermore, setting up a variety of different interfaces can enrich the application scenarios of the energy storage device 100 and improve the utilization rate of the energy storage device 100.

[0182] In some embodiments, the energy storage device 100 also includes a lighting device, which includes at least one or more of LED lamps, incandescent lamps, fluorescent lamps, magnesium lamps, xenon lamps, high-pressure pump lamps, high-pressure sodium lamps, and halogen lamps. The lighting device is disposed in the housing 10 and is capable of providing illumination.

[0183] Specifically, the lighting device is located within the housing 10, and its light emission direction is from inside the housing 10 to outside the housing 10. The lighting device can emit light to provide sufficient light to the user and achieve the lighting function. The lighting device includes at least one or more of the following: LED lamp, incandescent lamp, fluorescent lamp, magnesium lamp, xenon lamp, high-pressure pump lamp, high-pressure sodium lamp, and halogen lamp. It should be noted that the lighting device can also be other devices capable of emitting light, and there are no limitations on this.

[0184] In this way, by emitting light through the lighting device, the energy storage device 100 can have the function of emergency lighting, increasing the application scenarios of the energy storage device 100 and improving its application rate.

[0185] In some embodiments, the energy storage device 100 also includes an emergency start output interface, which is located in the housing 10 and is used for emergency vehicle start-up.

[0186] Specifically, the energy storage device 100 can serve as an emergency starting power source, providing electrical energy to the vehicle when the vehicle battery is depleted, enabling the vehicle to start in an emergency. The emergency start output interface of the energy storage device 100 is located in the housing 10, allowing the user to connect the emergency start output interface to the vehicle using an emergency start connection cable, enabling the energy storage device 100 to supply power to the vehicle and meet its emergency starting requirements. In some embodiments, the vehicle includes at least a truck, a car, or an electric vehicle.

[0187] Thus, through the emergency start output interface provided on the housing 10, the energy storage device 100 can be connected to the vehicle and provide power for emergency start-up of the vehicle.

[0188] In some implementations, the energy storage device 100 may also be a vehicle battery, providing power to the vehicle to enable it to start, or providing power to electrical equipment in the vehicle.

[0189] Please see Figure 11 In some embodiments, the energy storage device 100 further includes a positive terminal 90 and a negative terminal 110, which are connected to the energy storage module 30 and are used to connect to internal vehicle equipment to provide electrical energy for vehicle startup or power consumption.

[0190] Specifically, both the positive terminal 90 and the negative terminal 110 are connected to the energy storage module 30, which can discharge externally through the positive terminal 90 and the negative terminal 110. Users can connect the positive terminal 90 and the negative terminal 110 to internal vehicle equipment via connecting cables to establish a connection between the energy storage device 100 and the vehicle, enabling the energy storage device 100 to supply power to the vehicle to meet the power requirements for functions such as starting the vehicle.

[0191] Furthermore, the housing 10 includes a box body 13 and a cover 15. The positive terminal 90 and the negative terminal 110 can be disposed on the cover 15, and are located on opposite sides of the cover 15. In addition, the positive terminal 90 is marked with "positive" or "+", and the negative terminal 110 is marked with "negative" or "-", to facilitate accurate identification and connection of the positive and negative terminals by the user.

[0192] Thus, the connection between the vehicle's internal equipment and the energy storage device 100 can be achieved through the positive terminal 90 and the negative terminal 110, enabling the energy storage device 100 to provide electrical energy for vehicle starting or power consumption. In one embodiment, after the lithium-ion battery cell is installed in the battery cell interlayer inside the housing 10, the cover 15 and the box 13 are closed to ensure the airtightness of the housing 10. Then, the nitrogen tank is connected to a one-way valve using a gas pipe 500, and the target gas is filled in to make the internal pressure of the housing 10 approximately 0.5 MPa to 0.8 MPa. When the energy storage module 30 is in danger of overcharging, the battery cell experiences thermal runaway and deflagration. Due to the lack of oxygen, the combustion is unsustainable, and the flame is quickly extinguished. At the same time, the battery cell generates a large amount of gas, causing the internal pressure of the box 13 to rise sharply. When the internal pressure of the housing 10 exceeds the preset pressure, the blocking element 71 in the pressure relief valve 70 is ejected under pressure, the pressure relief valve 70 opens, and the gas is discharged from the pressure relief port. At this time, the internal air pressure of the casing 10 decreases, which prevents the casing 10 structure from bursting due to excessive pressure and causing an explosion. In addition, the rapid leakage of gas also allows the popping sound emitted through the narrow valve port to alert the user to evacuate quickly and protect the user's life safety.

[0193] Please see Figure 13 This application also provides an energy storage device 100, which includes a housing 10, an energy storage module 30, a target gas 14, and an electrical connection interface 16.

[0194] The housing 10 has a sealed space inside; the energy storage module 30100 is disposed inside the housing 10; the target gas 14 fills the inside of the housing 10; and the electrical connection interface 16 is disposed on the housing 10 and connected to the energy storage module 30.

[0195] The energy storage module 30 is housed inside the housing 10. The housing 10 provides support for the energy storage module 30 and offers collision protection.

[0196] Specifically, the energy storage device 100 can be used to release electrical energy to power loads. The energy storage device 100 supplies power externally through the electrical connection interface 16. The energy storage device 100 can provide power to equipment such as emergency power supplies, outdoor power supplies, and start-stop power supplies.

[0197] In an alternative embodiment, the housing 10 further includes an air port 11, through which the housing 10 is connected to a gas storage assembly 440, which is configured to fill the housing 10 with target gas 14 through the air port 11.

[0198] Optionally, the gas port 11 is sealed to prevent the target gas 14 from leaking from the gas port 11 to the outside of the housing 10, ensuring the safe operation of the energy storage device, avoiding safety hazards (such as combustion and explosion) caused by the leakage of the target gas 14, maintaining the environmental stability inside the housing 10, and improving the service life and safety of the energy storage device. The gas port 11 can be sealed by means of mechanical seal, adhesive seal, welding seal, threaded seal, heat fusion seal, etc., and is not limited here.

[0199] Optionally, the gas port 11 is sealed by a sealing element 18, which includes at least one of metal, colloid, plastic, elastomer, gas valve 50, piston, and sealing diaphragm. Thus, the type of sealing element 18 can be flexibly selected according to the structure of the gas port 11 of the energy storage device, the required pressure, and the characteristics of the target gas 14, effectively preventing leakage of the target gas 14, reducing safety hazards, and meeting diverse design and usage requirements.

[0200] Optionally, the seal 18 is formed by the sealing mechanism 600 through a heat-melting sealing process.

[0201] Specifically, the sealing mechanism 600 uses a hot-melt process to melt the sealing material (such as metal, plastic, hot melt adhesive, etc.) and fill the gaps using the fluidity of the molten material. After cooling at the gas port 11 of the energy storage device, it solidifies and forms an integrated seal 18. In this way, a seal 18 with strong structural integrity and tight sealing surface can be formed, thereby effectively preventing the leakage of the target gas 14, improving sealing reliability and equipment service life, and reducing maintenance costs.

[0202] Optionally, the edge structure of the air vent 11 includes an annular boss 12, and the sealing mechanism 600 is used to seal the annular boss 12. The material of the annular boss 12 includes plastic. Thus, by providing a clear sealing reference through the annular boss 12, the positioning accuracy and fit of the seal can be improved, enhancing the reliability of the sealing process. The plastic may include polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), etc., and is not limited thereto.

[0203] In one alternative embodiment, the target gas 14 includes an inert gas, and / or the target gas 14 includes at least one of nitrogen, helium, argon, neon, krypton, xenon, radon, and fluoride insulating gases.

[0204] When a high concentration of the target gas 14 is present inside the energy storage device 100, the oxygen content inside is relatively low, which can reduce the possibility of thermal runaway or deflagration of the energy storage module 30 inside the energy storage device 100. The gas storage component 440 is a component used to store the target gas 14, including gas cylinders, gas tanks, gas bags, etc.

[0205] This application provides safety protection from the perspective of overcharging. By filling the casing 10 with the target gas 14, the energy storage module 30 is placed in the non-flammable target gas 14 to isolate oxygen. This allows the deflagration caused by overcharging of the energy storage module 30 to be quickly extinguished, reducing the hazards caused by deflagration or thermal runaway of the energy storage module 30. In addition, keeping the energy storage module 30 in a low-oxygen environment for a long time helps to extend the service life of the energy storage module 30.

[0206] Optionally, the gas storage component 440 is a nitrogen tank. The air inlet 11 is located on one side of the housing 10 of the energy storage device 100, and the nitrogen tank can fill the housing 10 with nitrogen through the air inlet 11.

[0207] Optionally, the housing 10 may be made of metal or plastic.

[0208] The metals may include galvanized steel, stainless steel, aluminum alloy, aluminum-magnesium alloy, copper alloy, etc.; the plastics may include polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), etc.; the embodiments of this application are not limited herein.

[0209] The metal casing 10 is characterized by high strength, strong impact resistance and deformation resistance, which can effectively protect the internal energy storage module 30; it also has good thermal conductivity, which is conducive to heat dissipation and can prevent heat accumulation; at the same time, the metal casing 10 has good high temperature resistance, which can delay structural failure in the early stage of thermal runaway of the energy storage module 30; and it has a long service life, is resistant to aging and corrosion, and is suitable for a variety of complex environments.

[0210] The plastic casing 10 is lightweight, which can reduce the overall load of the energy storage device 100; it is also easy to process and mold, and complex casing structures can be customized; at the same time, the plastic casing 10 is low in cost, making it suitable for small and medium power energy storage devices 100; it also has good insulation, which can reduce the risk of electric shock, and strong resistance to chemical corrosion. Some plastic materials also have certain flame retardancy, making them suitable for dry operating environments.

[0211] Optionally, the material of the housing 10 may also include glass fiber reinforced resin, carbon fiber composite material, ceramic matrix composite material, etc., and this application embodiment does not limit this.

[0212] In one alternative embodiment, please refer to Figure 8 and Figure 9 The energy storage device 100 includes a gas valve 50, which is located at the gas port 11. The gas storage component 440 is connected to the gas valve 50 via a detachable gas pipe 500 to charge the target gas 14 into the housing 10 through the gas pipe 500.

[0213] Specifically, the gas valve 50 is located at the gas port 11 of the housing 10 of the energy storage device 100. The gas storage assembly 440 can be connected to the gas valve 50 via a detachable gas pipe 500, thereby achieving connection with the housing 10. When the gas storage assembly 440 is connected to the gas valve 50 via the gas pipe 500, the gas storage assembly 440 charges the housing 10 with the target gas 14 via the gas pipe 500.

[0214] The gas valve 50 can be a one-way valve, and the gas flow direction is from the outside of the housing 10 to the inside of the housing 10. The detachable gas pipe 500 means that the gas pipe 500 can be separated from the gas valve 50 and the gas storage component 440. In this case, the gas valve 50 prevents the gas inside the gas storage component 440 from flowing out. Alternatively, the gas pipe 500 can be connected at both ends to the gas valve 50 and the gas storage component 440 respectively, so that the gas storage component 440 can be filled with gas into the housing 10 through the gas pipe 500 and the gas valve 50. The detachable gas pipe 500 allows for easy filling with nitrogen to maintain the nitrogen concentration inside the housing 10 when there is a small amount of leakage inside the energy storage device 100 housing 10.

[0215] In one alternative embodiment, please refer to Figure 11 The energy storage device 100 also includes at least one pressure relief valve 70, which is used to release gas inside the housing 10 when the gas pressure inside the housing 10 is greater than a preset gas pressure.

[0216] It is understandable that if the energy storage module 30 malfunctions, it can easily generate a large amount of heat and gas, leading to an increase in the air pressure inside the housing 10 of the energy storage device 100. If the air pressure inside the housing 10 is too high, an explosion may easily occur due to excessive internal pressure.

[0217] The energy storage device 100 may include at least one pressure relief valve 70. The pressure relief valve 70 may be installed on the housing 10 of the energy storage device 100 and may connect the interior and exterior of the housing 10. When the gas pressure inside the housing 10 exceeds a preset pressure, the pressure relief valve 70 is activated, connecting the interior and exterior of the housing 10. At this time, due to the higher gas pressure inside the housing 10, the gas inside the housing 10 can be released to the outside of the energy storage device 100 through the pressure relief valve 70, thereby relieving pressure inside the energy storage device 100. By allowing a large amount of gas to be discharged through the pressure relief valve 70, an explosion due to excessive pressure inside the housing 10 can be prevented, reducing the possibility of open flames and preventing fires. Furthermore, it can protect personnel from shrapnel injuries from an explosion, providing a final line of defense.

[0218] The preset air pressure is the maximum pressure value that the pressure relief valve 70 can withstand, which can be determined according to the material of the pressure relief valve 70 and the size of the housing 10 of the energy storage device 100. For example, the preset air pressure ranges from 1 MPa to 5 MPa. That is to say, the preset air pressure can be 1.0 MPa, 1.1 MPa, 1.5 MPa, 2 MPa, 2.9 MPa, 3.5 MPa, 4.0 MPa, 4.5 MPa, 5 MPa, etc., without any restrictions.

[0219] Optionally, the preset air pressure ranges from 1 MPa to 1.0 MPa. In another embodiment, the preset air pressure ranges from 2 MPa to 5 MPa.

[0220] Optionally, the housing 10 includes a box body 13 and a cover 15 disposed on the box, and a pressure relief valve 70 may be disposed on the cover 15.

[0221] Optionally, please refer to Figure 11 The energy storage device 100 may include two pressure relief valves 70, both of which are installed on the cover 15 of the energy storage device 100.

[0222] Optionally, the vent valve 50 is a one-way valve, and the allowed gas flow direction is from the inside of the housing 10 of the energy storage device 100 to the outside of the housing 10.

[0223] Thus, by setting the pressure relief valve 70, the gas inside the housing 10 can be released when the gas pressure inside the housing 10 is too high, thereby reducing the gas pressure inside the housing 10 and preventing the housing 10 from exploding due to excessive gas pressure.

[0224] In one alternative embodiment, please refer to Figure 11A pressure relief valve 70 is disposed in the housing 10. The pressure relief valve 70 includes a blocking element 71, which is tightly connected to the pressure relief valve 70. The shape of the blocking element 71 may include a cone shape, a piston shape, etc. The blocking element 71 with a specific shape is adapted to the structure of the pressure relief valve 70, and the two are tightly connected to ensure the stability of the structure, ensuring that excessive pressure in the housing 10 can be effectively released, thereby improving overall safety.

[0225] In an alternative embodiment, when the air pressure inside the housing 10 is greater than a preset air pressure, the blocking member 71 separates from the pressure relief valve 70.

[0226] Specifically, when the air pressure inside the housing 10 is greater than the preset air pressure, the blocking member 71 separates from the pressure relief valve 70 under the pressure inside the housing 10, thereby opening the gas passage inside the pressure relief valve 70. When the blocking member 71 separates from the pressure relief valve 70, the gas inside the energy storage device 100 is released to the outside to relieve pressure.

[0227] In one optional embodiment, the material of the blocking member 71 includes rubber, PTFE (polytetrafluoroethylene), PU (polyurethane), etc. When the air pressure inside the housing 10 is less than or equal to the preset air pressure, the blocking member 71 is tightly connected to the pressure relief valve 70 to block the gas passage of the pressure relief valve 70 and block the flow of gas inside and outside the housing 10.

[0228] Thus, by including the pressure relief valve 70 with the blocking member 71 and the blocking member 71 being tightly connected to the pressure relief valve 70, under normal conditions, the gas inside the housing 10 of the energy storage device 100 will not flow to the outside through the pressure relief valve 70, and the external gas will not flow into the housing 10 through the pressure relief valve 70, thereby ensuring the concentration of the target gas 14 inside the energy storage device 100 under normal conditions.

[0229] Optionally, the valve port size of the pressure relief valve 70 is smaller than the preset size, and the pressure relief valve 70 can generate a popping sound when it is in a pressure-relieving state.

[0230] Specifically, the preset size is a pre-set value that can be set according to actual needs, and a pressure relief valve 70 that meets the requirements can be selected based on the preset size. For pressure relief valves 70 with a valve orifice size smaller than the preset size, when the pressure relief valve 70 is in a pressure-relief state, a popping sound will be generated due to the rapid flow of gas at the valve orifice. The popping sound generated by the pressure relief valve 70 itself can alert the user to deal with the abnormality of the energy storage device 100 in time, or to take timely precautions, without the need for additional sound-generating devices such as buzzers, simplifying the structural design of the energy storage device 100 and contributing to its lightweight design.

[0231] Thus, by setting a vent valve 5070 with a smaller valve opening, a popping sound can be generated when the gas is discharged, producing a sharp noise to remind the user to quickly cut off the power and evacuate.

[0232] In one alternative embodiment, please refer to Figure 9 The housing 10 includes a box body 13, a cover body 15, and a sealing strip 17, with the box body 13 and the cover body 15 being sealed together by the sealing strip 17.

[0233] Specifically, the box body 13 and the cover body 15 are arranged opposite each other, and a sealing strip 17 is provided between the box body 13 and the cover body 15 so that the box body 13 and the cover body 15 are sealed together by the sealing strip 17.

[0234] Thus, the sealed connection formed by the housing 13, the cover 15 and the sealing strip 17 allows the housing 10 to facilitate the installation of internal components while also having high airtightness, providing additional waterproof performance for the energy storage device 100 and improving the safety protection level of the energy storage device 100.

[0235] Please see Figure 12 In some embodiments, the housing 13 forms at least one accommodating cavity 131, which is configured to accommodate the energy storage module 30.

[0236] Specifically, the energy storage module 30 includes at least one battery cell. The housing 13 forms at least one battery cell interlayer, each forming a receiving cavity 131. Each battery cell can be disposed within one receiving cavity 131. Forming the battery cell interlayer within the housing 13 facilitates the installation of the battery cell into the energy storage module 30 before closing the cover 15 and housing 13, thus facilitating the installation of the energy storage device 100. Furthermore, the housing 13 provides protection for the energy storage module 30, preventing it from being impacted.

[0237] Optionally, the energy storage device 100 includes three cell sandwich layers, with one cell placed in each cell sandwich layer. In this way, the receiving cavity 131 formed by the housing 13 allows the housing 13 and cover 15 to be closed after the energy storage module 30 is installed into the receiving cavity 131, which facilitates the installation of the energy storage module 30.

[0238] In one optional embodiment, the energy storage module 30 includes a rechargeable battery and / or a supercapacitor, wherein the rechargeable battery includes at least one of a sodium battery or a lithium battery. For example, the energy storage module 30 can be at least one of a lithium cobalt oxide battery, a lithium manganese oxide battery, a lithium iron phosphate battery, or a nickel-cobalt-manganese lithium battery. In the event of an overcharge or other abnormality in the energy storage module 30, the rapidly generated large amount of heat and gas may lead to deflagration and / or thermal runaway, causing equipment damage and endangering the user's life safety.

[0239] An air inlet 11 is formed on the housing 10 of the energy storage device 100 of this application embodiment. The housing 10 can be connected to a gas storage assembly 440 through the air inlet 11, so that the gas storage assembly 440 can fill the housing 10 with the target gas 14.

[0240] In one alternative embodiment, the housing 13 and the cover 15 are made of materials including PC (polycarbonate), ABC, plastic and / or nylon.

[0241] Specifically, considering the pressure-bearing capacity of the energy storage device 100, the cover 15 can be made of PC, ABC, plastic, and / or nylon. The enclosure 13 and / or cover 15 are manufactured to meet pressure-bearing requirements while satisfying cost constraints, enabling them to withstand certain external pressure or impacts and protect the internal energy storage module 30 from easy damage. ABC material includes plastic alloy, plastic blend, and filled reinforced composite plastic. Those skilled in the art can also choose other suitable materials to manufacture the enclosure 13 or cover 15 as needed; no restrictions are imposed here.

[0242] Optionally, the materials of the housing 13 and the lid 15 can be different or the same, and there is no limitation on this. Optionally, both the housing 13 and the lid 15 can be made of PC material and ABC material. In this way, by using PC material, ABC material, plastic material and / or nylon material to make the housing 13 and the lid 15, the pressure resistance requirements of the housing 13 and the lid 15 can be met.

[0243] In one optional embodiment, the pressure of the target gas 14 injected into the housing 10 ranges from 0.05 MPa to 1.2 MPa. That is, the pressure of the target gas 14 injected into the housing 10 can be 0.05 MPa, 0.1 MPa, 0.3 MPa, 0.5 MPa, 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.2 MPa, etc. Preferably, the pressure of the target gas 14 injected into the housing 10 ranges from [0.1 MPa, 1.0 MPa].

[0244] In one optional embodiment, the pressure of the target gas 14 introduced into the housing 10 ranges from [0.5 MPa to 0.8 MPa]. Thus, the non-flammable target gas 14 is introduced into the housing 10 through the gas storage assembly 440, ensuring that the housing 10 is continuously filled with the target gas 14. In the event of thermal runaway of the battery within the housing 10, the lack of oxygen prevents continued combustion, allowing the flame to be quickly extinguished, thereby preventing further serious consequences after the battery's thermal runaway.

[0245] In one optional embodiment, the volume of the gas storage component 440 includes 40L, 50L, 60L, 70L, 80L, etc., which can be set according to actual needs.

[0246] In one optional embodiment, the energy storage device 100 is an emergency power source, the target gas 14 is nitrogen, and the gas storage assembly 440 is a nitrogen cylinder. A one-way valve 50 is matched with the nitrogen cylinder. If the energy storage device 100 has a small leak, it needs to be refilled. This can be done by connecting the nitrogen cylinder and the one-way valve 50 on the emergency power source housing 10 via a gas hose 500, and then refilling the emergency power source housing 10 with nitrogen through the gas hose 500.

[0247] Thus, by connecting the gas valve 50 to the detachable gas pipe 500, the gas storage assembly 440 can be inflated into the housing 10. The gas valve 50 also prevents the gas inside the housing 10 from leaking to the outside when unnecessary, ensuring the airtightness of the housing 10.

[0248] In one alternative embodiment, please refer to Figure 13 The energy storage device 100 also includes an electrical connection interface 16, which includes at least one of a USB interface, an AV port, a DC interface, and a cigarette lighter port. The electrical connection interface 16 is connected to the energy storage module 30 of the energy storage device 100.

[0249] Specifically, the electrical connection interface 16 can be used to connect external devices to supply power to them. The electrical connection interface 16 may include, but is not limited to, a USB interface, an AV (composite video) jack, a DC (direct current) jack, a cigarette lighter jack, etc. Users can connect external devices to the electrical connection interface 16 via specific connecting cables to obtain power from the energy storage device 100, according to their own needs.

[0250] Optionally, users can connect the electrical device to the energy storage device 100 via a USB interface and a USB cable to use the energy storage device 100 to charge and / or supply power to the electrical device.

[0251] Thus, external devices can be connected through the electrical connection interface 16 to enable the energy storage module 30 to supply power to external devices. Furthermore, setting up a variety of different interfaces can enrich the application scenarios of the energy storage device 100 and improve the utilization rate of the energy storage device 100.

[0252] Optionally, the energy storage device 100 also includes a lighting device, which includes at least one or more of the following: LED lamp, incandescent lamp, fluorescent lamp, magnesium lamp, xenon lamp, high-pressure pump lamp, high-pressure sodium lamp, and halogen lamp. The lighting device is disposed in the housing 10 and is capable of providing illumination.

[0253] Specifically, the lighting device is located within the housing 10, and its light emission direction is from inside the housing 10 to outside the housing 10. The lighting device can emit light to provide sufficient light to the user and achieve the lighting function. The lighting device may include, but is not limited to: LED lights, incandescent lamps, fluorescent lamps, magnesium lamps, xenon lamps, high-pressure pump lamps, high-pressure sodium lamps, halogen lamps, etc. It should be noted that the lighting device can also be other devices capable of emitting light, and there are no restrictions on this.

[0254] In this way, by emitting light through the lighting device, the energy storage device 100 can have the function of emergency lighting, increasing the application scenarios of the energy storage device 100 and improving its application rate.

[0255] In one alternative embodiment, please refer to Figure 14 The energy storage device 100 also includes an emergency start output interface 20, which is located in the housing 10 and is used for emergency vehicle start-up.

[0256] Specifically, the energy storage device 100 can be an emergency starting power source to provide electrical energy to the vehicle when the vehicle battery is depleted, enabling the vehicle to start in an emergency. The emergency start output interface 20 of the energy storage device 100 is located in the housing 10, allowing the user to connect the emergency start output interface 20 to the vehicle using an emergency start connection cable, so that the energy storage device 100 can supply power to the vehicle to meet the electrical energy required for emergency starting. Optionally, the vehicle may include, but is not limited to, trucks, cars, electric vehicles, motorcycles, etc.

[0257] Thus, the energy storage device 100 can be connected to the vehicle and provide power for the vehicle's emergency start through the emergency start output interface 20 provided on the housing 10.

[0258] Alternatively, the energy storage device 100 may also be a vehicle battery, providing electrical power to the vehicle to enable it to start, or providing electrical power to electrical equipment in the vehicle.

[0259] In one alternative embodiment, please refer to Figure 15 The energy storage device also includes a connection component 40, which connects to internal vehicle equipment to output current for vehicle startup or power consumption. The connection component 40 functions similarly to the emergency start output interface 20, acting as a medium for energy transfer, enabling the transfer of electrical energy from the energy storage device to the vehicle to ensure normal vehicle power supply.

[0260] In one alternative embodiment, please refer to Figure 11The energy storage device 100 also includes a positive terminal 90 and a negative terminal 110, which are connected to the energy storage module 30. The positive terminal 90 and the negative terminal 110 are used to connect to the vehicle's internal equipment to provide the required electrical energy for starting the vehicle or for power consumption.

[0261] Specifically, both the positive terminal 90 and the negative terminal 110 are connected to the energy storage module 30, which can discharge externally through the positive terminal 90 and the negative terminal 110. Users can connect the positive terminal 90 and the negative terminal 110 to the vehicle's internal equipment via connecting cables to establish a connection between the energy storage device 100 and the vehicle, thereby enabling the energy storage device 100 to supply power to the vehicle to meet the power requirements of functions such as vehicle starting.

[0262] Optionally, the housing 10 includes a box 13 and a cover 15. The positive terminal 90 and the negative terminal 110 can be disposed on the cover 15, respectively, on both sides of the cover 15. Furthermore, the positive terminal 90 may be marked with "positive" or "+", and the negative terminal 110 may be marked with "negative" or "-", to facilitate accurate identification and connection of the positive and negative terminals by the user.

[0263] Thus, the vehicle's internal equipment can be connected to the energy storage device 100 through the positive terminal 90 and the negative terminal 110, thereby enabling the energy storage device 100 to provide electrical energy for vehicle startup or power consumption.

[0264] In some embodiments, after the lithium-ion battery cell is installed in the cell interlayer inside the housing 10, the cover 15 and the box 13 are closed to ensure the airtightness of the housing 10. Then, a nitrogen cylinder is connected to a one-way valve 50 via a gas pipe 500, and the target gas 14 is introduced to make the internal pressure of the housing 10 approximately 0.5 MPa to 0.8 MPa. In the event of an overcharge hazard in the energy storage module 30, the battery cell experiences thermal runaway and deflagration. However, due to the lack of oxygen, the combustion is unsustainable, and the flame is quickly extinguished. Simultaneously, the battery cell generates a large amount of gas, causing a sudden increase in pressure inside the box 13. When the internal pressure of the housing 10 exceeds the preset pressure, the blocking element 71 in the pressure relief valve 70 is ejected under pressure, the pressure relief valve 70 opens, and gas is discharged from the pressure relief port. At this time, the internal pressure of the housing 10 decreases, thus preventing the housing 10 structure from bursting due to excessive pressure and causing an explosion. In addition, the rapid leakage of gas can also alert users to evacuate quickly by making a popping sound when passing through a narrow valve opening, thus protecting their lives.
