Description

Technical Field

[0001] This application belongs to the field of energy storage technology, specifically relating to an energy storage module and an energy storage cabinet. Background Technology

[0002] With the rapid development of energy storage technology, energy storage products are widely used in various scenarios, including new energy power plants, data centers, and electric vehicles. As the core component of an energy storage system, the energy storage module typically consists of multiple battery cells, and its safety directly affects the stable operation of the energy storage system. However, existing energy storage modules and PACK designs have some serious safety hazards, especially the lack of thermoelectric separation functionality, which has become a key issue restricting the further development of energy storage technology.

[0003] In current energy storage module and PACK designs, thermal-electric separation is not yet fully realized. Traditional designs typically employ high-temperature resistant sampling lines or simply shield the sampling line bundle to reduce the impact of thermal runaway on the voltage sampling lines. While these methods improve the withstand capability of the voltage sampling lines to some extent, they do not fundamentally solve the problem of complete separation between heat and the voltage sampling conductor. When a cell experiences thermal runaway, its explosion-proof valve releases high-temperature, high-pressure flammable gas. This gas readily comes into direct contact with the surrounding voltage sampling line bundle, causing the bundle sheath to melt and form a short circuit. The electrical sparks generated by the short circuit may not only further ignite the flammable gas released from the explosion-proof valve but may also trigger a chain reaction, leading to a large-scale fire throughout the entire energy storage module.

[0004] Therefore, it is necessary to provide a new solution to the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this application is to provide an energy storage module and energy storage cabinet that can effectively solve the problem of the lack of thermoelectric separation function in the prior art and avoid the short circuit and fire hazards caused by direct contact between high temperature gas and voltage sampling line.

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] In a first aspect, this application provides an energy storage module, which includes a battery assembly and a housing; the battery assembly includes a plurality of battery cells arranged in sequence, and the battery cells are provided with explosion-proof valves on their sides; the housing forms a receiving space for accommodating the battery assembly, and the housing includes a frame disposed on both sides of the battery assembly and restricting the lateral displacement of the battery cells, the frame is provided with an exhaust channel and a plurality of exhaust holes corresponding to and communicating with the explosion-proof valves, and the exhaust holes are connected to the exhaust channel.

[0008] In one or more embodiments, the frame includes a frame extending along the cell arrangement direction, and the exhaust channel and the exhaust hole are both provided on the frame.

[0009] In one or more embodiments, a sealing gasket is provided between the vent and the explosion-proof valve, and the sealing gasket is attached to the frame.

[0010] In one or more embodiments, one end of the frame is provided with an outlet, which is connected to the exhaust channel.

[0011] In one or more embodiments, the frame has a hollowed-out area in the middle for accommodating the battery cells.

[0012] In one or more embodiments, the housing further includes a front end plate and a rear end plate for limiting the front-to-back displacement of the battery cell, the front end plate and the rear end plate being fixedly connected to the front and rear ends of the frame, respectively.

[0013] In one or more embodiments, a battery management unit connected to the battery assembly is mounted on the front-end board.

[0014] In one or more embodiments, a buffer heat insulation sheet is provided between any two adjacent battery cells.

[0015] In one or more embodiments, the energy storage module includes multiple sets of stacked battery components, with a cooling plate between two adjacent sets of battery components. The width of the cooling plate is smaller than the width of the battery cell unit to form a gap between the sides of two adjacent sets of battery components, and the gap is filled with foam.

[0016] Secondly, this application provides an energy storage cabinet that includes the aforementioned energy storage module.

[0017] Compared with existing technologies, the energy storage module and energy storage cabinet provided in this application, by setting exhaust channels and exhaust holes on the frame and connecting them to the cell explosion-proof valve, can quickly exhaust the high-temperature gas released during thermal runaway to the outside of the module, avoiding direct contact between the high-temperature gas and the voltage sampling line, achieving thermoelectric separation, and reducing the risk of short circuits and fires. In addition, a cooling plate is set between adjacent battery modules, and the outside of the cooling plate is wrapped with foam, which not only improves heat dissipation efficiency, but also avoids the condensation and leakage problems common in traditional liquid cooling systems through the isolation effect of the foam, ensuring long-term stable operation of the system.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0027] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0028] With the widespread application of energy storage technology, the safety and reliability of energy storage modules, as the basic unit of energy storage systems, have attracted much attention. However, existing energy storage modules and PACKs have many design limitations, especially in dealing with cell thermal runaway and the resulting high-temperature, high-pressure flammable gases, for which effective technical means have not yet been developed. Traditional solutions mostly rely on improving the high-temperature resistance of voltage sampling lines or adopting simple physical isolation measures. However, these methods cannot fundamentally eliminate direct contact between high-temperature gases and voltage sampling lines, and the risks of short circuits and fires still exist.

[0029] To address the aforementioned shortcomings of existing technologies, this application proposes a novel energy storage module design concept. This energy storage module, by introducing a thermoelectric separation concept, aims to structurally prevent direct contact between high-temperature gases and voltage sampling lines, thereby significantly reducing the risk of short circuits and fires. The core of this solution lies in optimizing the module structure to construct an independent collection and exhaust pathway for high-temperature gases. This allows the high-temperature gases released during thermal runaway of the battery cell to be rapidly guided outside the module and ultimately discharged into the environment through the energy storage cabinet.

[0030] To further enhance the performance and safety of the energy storage module, this invention also improves the cooling system design. By optimizing the thermal management path, this application achieves efficient heat dissipation directly at the module level, avoiding the condensation and leakage problems found in traditional liquid cooling systems. Simultaneously, the overall design adopts modularity and integration, simplifying the manufacturing and installation process while improving the system's scalability and ease of maintenance.

[0031] Please refer to Figures 1 to 5 As shown, an energy storage module in one embodiment of this application can be integrated into an energy storage cabinet. The energy storage module includes a battery assembly 1 and a housing 2. The battery assembly 1 includes a plurality of battery cell units 11 arranged in sequence, and an explosion-proof valve 111 is provided on the side of the battery cell unit 11. The housing 2 forms a receiving space 21 for accommodating the battery assembly 1. The housing 2 includes a frame 22 disposed on both sides of the battery assembly 1 and restricting the lateral displacement of the battery cell units 11. The frame 22 is provided with an exhaust channel 221 and a plurality of exhaust holes 222 corresponding to and communicating with the explosion-proof valve 111. The exhaust holes 222 are connected to the exhaust channel 221.

[0032] One of the core components of the energy storage module is the battery assembly 1, which is composed of multiple battery cell units 11 stacked sequentially. Each battery cell unit 11 has an explosion-proof valve 111 on its side. These valves automatically open in the event of thermal runaway, releasing high-temperature, high-pressure flammable gas to prevent the cell from rupturing or exploding due to excessive internal pressure. The explosion-proof valves 111 are positioned on the sides of the battery cell units 11 to ensure that high-temperature gas can be rapidly released from the sides of the battery cell units 11 in the event of thermal runaway, avoiding the risk of overheating.

[0033] To effectively guide these high-temperature gases, the energy storage module is designed with a matching outer casing 2. This casing 2 not only houses the battery assembly 1 but also provides structural support and safety protection. The interior of the casing 2 forms a containment space 21, ensuring the stable arrangement and position of the battery cells 11 during operation. Frames 22 are provided on both sides of the casing 2. These frames 22 not only restrict the lateral displacement of the battery cells 11, preventing mechanical damage caused by cell displacement under vibration or impact, but also provide exhaust channels 221 for the collection and guidance of high-temperature gases.

[0034] Multiple vents 222 are provided on the frame 22, and these vents 222 correspond one-to-one with and are connected to the explosion-proof valves 111 on the side of the battery cell unit 11. When the battery cell experiences thermal runaway, the explosion-proof valves 111 release high-temperature gases, which enter the exhaust channel 221 through the vents 222. The exhaust channel 221 is designed to run through the entire frame 22, which can efficiently collect and guide the high-temperature gases to be discharged to the outside of the module. The exhaust channel 221 not only ensures that the high-temperature gases are quickly discharged, avoiding accumulation inside the module and reducing the risk of fire, but also, through connection with the pipes on the energy storage cabinet, safely discharges the high-temperature gases to the external environment of the energy storage cabinet, further improving the safety of the system.

[0035] Furthermore, the design of the exhaust channel 221, which connects to the piping on the energy storage cabinet, allows high-temperature gases to be smoothly discharged outside the cabinet through its exhaust system, preventing the formation of a high-temperature, high-pressure environment inside the cabinet and thus protecting the safe operation of other electrical components and wiring. The piping system on the energy storage cabinet is typically designed with multi-stage filtration and cooling devices to further ensure that the discharged gases do not adversely affect the external environment and also prevent damage to the energy storage cabinet structure due to excessively high gas temperatures.

[0036] In one exemplary embodiment, please refer to Figures 1 to 5 As shown, the frame 22 includes a frame 223 extending along the arrangement direction of the battery cells 11, and exhaust channels 221 and exhaust holes 222 are both provided on the frame 223. As part of the outer shell 2, the frame 22 plays an important role in support, positioning, and guiding high-temperature gas. The core component of the frame 22 is the frame 223 extending along the arrangement direction of the battery cells 11. The frame 223 is not only the backbone of the module structure, but also provides the necessary physical carrier and spatial support for the arrangement of exhaust channels 221 and exhaust holes 222.

[0037] The frame 223 can be designed as a cuboid or other regular shape, consistent with the stacking direction of the battery cell 11. This design makes full use of space and provides solid lateral support for the battery cell 11, preventing displacement of the cells due to vibration or external forces during use. The extension length of the frame 223 in the battery cell stacking direction covers the entire arrangement range of the battery assembly 1, thereby ensuring that the sides of each battery cell are fixed and protected by the frame 22.

[0038] Exhaust channels 221 and exhaust ports 222 are arranged on the frame 223. These designs take into account the position and airflow path of the explosion-proof valves 111 on the side of the battery cell 11. The position of each exhaust port 222 corresponds one-to-one with the explosion-proof valve 111 of the battery cell, ensuring that when the explosion-proof valve 111 is opened, high-temperature gas can quickly enter the exhaust channel 221 through the shortest path, thereby preventing gas from diffusing to other areas of the module. The size of the exhaust port 222 is designed to fully accommodate the gas flow rate ejected from the explosion-proof valve 111 while maintaining the internal sealing of the module.

[0039] The exhaust channel 221 extends along the frame 223, covering the side of the battery module 1, providing a main pathway for the collection and guidance of high-temperature gases. The exhaust channel 221 is designed to rapidly dissipate large amounts of gas in the event of thermal runaway, while maintaining an unobstructed gas emission path. This structural design allows gas from each exhaust port 222 to be concentrated within the exhaust channel 221, and then safely discharged to the outside of the energy storage cabinet through the exhaust pipe system. This distributed collection and centralized guidance mode effectively avoids gas stagnation inside the module, thereby reducing the risk of high temperatures and fires that may result from gas accumulation.

[0040] The frame 223 is preferably made of high-strength, high-temperature resistant insulating material to prevent deformation or failure in high-temperature environments, and its surface can be insulated to avoid electrical contact with the battery cell 11, thereby avoiding the risk of electrical short circuit.

[0041] Specifically, please refer to Figure 1 and Figure 4 As shown, a sealing gasket 2224 is provided between the vent 222 and the explosion-proof valve 111, and the sealing gasket 2224 is attached to the frame 223. The main function of the sealing gasket 2224 is to ensure that in the event of thermal runaway of the battery cell 11, high-temperature gas can be guided through the explosion-proof valve 111 to the vent 222 and eventually enter the exhaust channel 221 without leakage or interference with the operation of other components inside the module.

[0042] The sealing gasket 2224 is tightly attached to the frame 223 and is kept stable by the combined action of the explosion-proof valve 111 and the frame 223. During the assembly of the module, a certain pressure is applied between the battery cell 11 and the frame 223, causing the sealing gasket 2224 to deform moderately under the compression of both. This deformation can form a reliable airtight contact between the vent 222 and the explosion-proof valve 111, ensuring that high-temperature gas completely enters the exhaust channel 221 through the vent 222 without gas leakage. The material of the sealing gasket 2224 can be a flexible and high-temperature resistant insulating material, such as silicone or fluororubber, to ensure that it does not melt or deform under the action of high-temperature gas, thereby maintaining long-term stable sealing performance.

[0043] In addition to its airtight function, the sealing gasket 2224 also provides electrical isolation. Since there may be a potential difference between the explosion-proof valve 111 and the frame 223, and the frame 223 is part of the module structure and may be connected to other electrical components, failure to provide effective electrical isolation could lead to short circuits or electrical sparks, further exacerbating safety hazards. The sealing gasket 2224, made of insulating material, prevents current conduction by isolating the explosion-proof valve 111 from direct contact with the frame 223, thus ensuring the overall electrical safety of the module.

[0044] Further, please refer to Figure 4 and Figure 5 As shown, one end of the frame 223 is provided with an outlet 225, which is connected to the exhaust channel 221. The outlet 225, as the terminal structure of the exhaust channel 221, is the outlet for high-temperature gas to be discharged from the inside of the module. It is designed as an interface that can be connected to the pipes of the energy storage cabinet to realize the interconnection between the exhaust system of the module and the energy storage cabinet.

[0045] To achieve seamless connection between the module and the energy storage cabinet, the 225mm outlet port can be designed as a standard interface, matching the interface size and shape of the energy storage cabinet's piping. This interface design not only facilitates the assembly of the module and the cabinet but also further prevents gas leakage through a sealed connection, ensuring the airtightness and reliability of the entire gas management system.

[0046] The exhaust port 225 also plays an important auxiliary role in the thermal management and safety performance of the entire module. By connecting with the energy storage cabinet pipeline, the exhaust port 225 extends the gas management at the module level to the system level, so that the high-temperature gas can be discharged to the external environment through the multi-stage exhaust system of the energy storage cabinet.

[0047] The material chosen for the outlet 225 is typically a high-temperature and corrosion-resistant material, such as metal or high-performance polymer, to ensure structural integrity during long-term operation or thermal runaway events, protecting it from high-temperature or corrosive gases. Furthermore, additional seals can be fitted around the outlet 225 to further enhance airtightness and mechanical stability when connected to the energy storage tank piping.

[0048] In one exemplary embodiment, please refer to Figure 1 and Figure 5 As shown, the frame 22 has a hollowed-out area 226 in the middle for accommodating the battery cell strip (CCS), through which the battery cell strip can be connected to the battery cell unit 11. The hollowed-out area 226 is designed to be located in the middle of the frame 22, and its shape and size are sufficient to accommodate the installation and operation of the battery cell strip. The battery cell strip, as an electrical connection component of the battery cell unit 11, is used to connect the positive and negative conductive areas of multiple battery cell units 11 in a unified manner to form a module-level electrical output path. The hollowed-out area 226 provides an installation area for the battery cell strip, allowing it to pass smoothly through the frame 22 and be welded to the electrodes of the battery cell unit 11.

[0049] In one exemplary embodiment, please refer to Figure 1 and Figure 5 As shown, the outer casing 2 also includes a front end plate 23 and a rear end plate 24 that restrict the front and rear displacement of the battery cell unit 11. The front end plate 23 and the rear end plate 24 are respectively fixedly connected to the front and rear ends of the frame 22 to clamp the battery cell unit 11 from the front and rear directions.

[0050] The main function of the front end plate 23 and the rear end plate 24 is to provide mechanical constraints in the front-to-back direction for the battery cell unit 11, preventing the battery cell unit 11 from shifting forward or backward due to vibration, impact, or thermal expansion and contraction during assembly or operation. By clamping the front end plate 23 and the rear end plate 24, the battery cell unit 11 can be firmly fixed inside the frame 22, ensuring that the battery cell always maintains the correct position arrangement, thereby avoiding friction or contact failures caused by displacement between the battery cells.

[0051] The design of the front-end board 23 and the rear-end board 24 is based on the internal spatial layout of the module and the size characteristics of the battery cell 11. They can be made of high-strength, corrosion-resistant materials to cope with mechanical stress and environmental changes during long-term operation. The front and rear boards are connected to the frame 22 by bolts. This connection method not only ensures sufficient mechanical strength but also facilitates quick disassembly and assembly of the module when maintaining or replacing the battery cell 11.

[0052] The front-end board 23 serves not only as a mechanical support but also as a carrier for mounting other electrical components. For example, the battery management unit 5 (BMU) can be fixed to the front-end board 23 and, through electrical connection with the cell unit 11, enables the monitoring and control of the cells inside the module. The rear-end board 24 further enhances the rigidity of the module structure, giving the entire module greater stability when subjected to external forces.

[0053] In one exemplary embodiment, please refer to Figure 1 As shown, a buffer heat insulation sheet 12 is provided between any two adjacent battery cell units 11. The function of the buffer heat insulation sheet 12 is not only to improve the mechanical stability of the module, but also to deal with the expansion and heat management problems of the battery cell during operation through its heat insulation and buffering functions.

[0054] The material of the buffer heat insulation sheet 12 is preferably a flexible and high-temperature resistant heat insulation material, such as silicone, ceramic fiber, or high-performance polymer. This material selection can meet the stability requirements in high-temperature environments while also possessing a certain degree of flexibility, providing a good buffering effect when the volume of the battery cell 11 changes due to charging and discharging. During the charging process, the battery cell 11 usually undergoes slight expansion due to chemical reactions. If this expansion is not effectively absorbed, it may lead to compression or even mechanical damage between adjacent cells. The flexible design of the buffer heat insulation sheet 12 is precisely to solve this problem, absorbing the expansion force and avoiding direct contact between the cells and the accumulation of mechanical stress.

[0055] Besides its buffering function, thermal insulation is another core function of the buffer insulation sheet 12. During operation, the battery cell 11 generates heat, especially under high-power charging and discharging or high ambient temperature conditions. The accumulation of heat may lead to thermal interference between adjacent cells or even trigger thermal runaway events. By forming a thermal barrier between the battery cell 11, the buffer insulation sheet 12 reduces the heat transfer rate, thereby effectively reducing thermal coupling between adjacent cells and improving the overall thermal management performance of the module.

[0056] In one exemplary embodiment, please refer to Figure 1 and Figure 3 As shown, the energy storage module includes multiple stacked battery modules 1. A cooling plate 3 is provided between two adjacent battery modules 1. The width of the cooling plate 3 is smaller than the width of the cell unit 11, so as to form a gap 4 between the sides of two adjacent battery modules 1. The gap 4 is filled with foam.

[0057] A cooling plate 3 (such as a direct cooling plate) is positioned between two adjacent battery modules 1, its core function being to provide an efficient heat dissipation path for the battery modules 1. The width of the cooling plate 3 is designed to be smaller than the width of the cell unit 11. This dimensional optimization aims to leave a certain gap 4 on the side of the battery module 1 for filling with foam. The design of the gap 4 provides space for foam filling, which increases the structural stability and insulation performance. The material of the cooling plate 3 can be selected from materials with excellent thermal conductivity and high temperature resistance, such as aluminum alloy or copper alloy, to ensure that the heat generated by the battery module 1 can be quickly conducted and dissipated in high-temperature environments.

[0058] The outer side of the cooling plate 3 is wrapped with foam. The foam is flexible and has thermal insulation properties, which not only provides mechanical cushioning for the cooling plate 3 and absorbs the stress generated by the expansion of the battery assembly 1, but also prevents short circuits or mechanical wear that may be caused by direct contact between the cooling plate 3 and the battery assembly 1 or other components. At the same time, the foam filling reduces the direct contact between the cooling plate 3 and the ambient air, avoiding condensation problems caused by the low surface temperature of the cooling plate 3, thereby further improving the operational reliability of the module.

[0059] This application also provides an energy storage cabinet, which includes a cabinet body and the aforementioned energy storage module installed inside the cabinet body. The exhaust channel on the outer shell of the energy storage module is connected to the exhaust pipe of the energy storage cabinet.

[0060] In summary, the energy storage module and cabinet provided in this application, by setting exhaust channels and exhaust holes on the frame and connecting them to the cell explosion-proof valve, can quickly exhaust the high-temperature gas released during thermal runaway to the outside of the module, avoiding direct contact between the high-temperature gas and the voltage sampling line, achieving thermoelectric separation, and reducing the risk of short circuits and fires. Furthermore, by setting cooling plates between adjacent battery modules, with the outer side of the cooling plates wrapped in foam, not only is heat dissipation efficiency improved, but the insulation effect of the foam also avoids the condensation and leakage problems common in traditional liquid cooling systems, ensuring long-term stable operation of the system.

[0061] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0062] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
