The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. Those skilled in the art will appreciate that embodiments described herein can be combined with other embodiments.

[0031] The present application will be described in detail below with reference to the drawings and embodiments.

[0032] Please refer to Figure 1 , Figure 1 is an exploded view of an embodiment of the backup power supply of the present application.

[0033] In the present embodiment, the backup power supply 1 includes a battery mounting mechanism 10 and a plurality of battery cells 20 connected to the battery mounting mechanism 10.

[0034] It is worth mentioning that the backup power supply 1 can be a BBU, a functional component for providing emergency power support, mainly used to prevent data loss and service interruption caused by power failure. BBU provides temporary power supply for the system when power failure occurs, ensuring that critical equipment can continue to run or shut down safely, thereby protecting data and system integrity.

[0035] BBU automatically takes over the power supply task when power failure occurs, usually within a few minutes. It can be used in core IT (Information Technology) equipment such as servers, data centers, communication base stations, etc., to ensure that data and systems can still operate normally when power problems occur. BBU is usually combined with UPS (Uninterruptible Power Supply), diesel generators and other equipment to form a multi-level backup power supply solution to meet different time and power requirements; it can be distributed and embedded in server cabinets as needed for flexible configuration.

[0036] Among them, a plurality of battery cells 20 constitute the core energy storage unit of the backup power supply 1, providing the required power support; the battery mounting mechanism 10 provides physical support and fixing structure for the battery cells 20; a plurality of battery cells 20 are connected to the battery mounting mechanism 10 in a specific way to form a modular pack assembly, i.e. the backup power supply 1.

[0037] Specifically, please refer to Figures 2-4 Among them, Figure 2 is Figure 1 the structure diagram of the positive and negative electrode supports in the parallel group support of the backup power supply in Figure 3 is Figure 2 the structure diagram of the positive and negative electrode supports from another perspective in Figure 4 is Figure 2 the structure diagram of the positive and negative electrode supports from another perspective in. In this embodiment, the battery mounting mechanism specifically includes at least one parallel group support 11.

[0038] Among them, the battery mounting mechanism 10 provided in the present application is applied to the backup power supply 1, such as the BBU of a server, and is specifically used to arrange a plurality of battery cells 20 in a specific way to form a modular pack assembly. Of course, in other embodiments, the battery mounting mechanism 10 can also be specifically used in the backup power supply of communication equipment, medical equipment or other any reasonable electronic equipment, and the present embodiment does not limit this.

[0039] Specifically, each parallel group holder 11 is composed of two parts, namely a positive holder 111 and a negative holder 112 which is detachably connected to the positive holder 111, so that the negative holder 112 can be easily removed when maintenance or replacement of the battery is required, thereby contacting or removing the battery cell 20.

[0040] The positive holder 111 is provided with two rows of first receiving holes 1101, and the corresponding negative holder 112 is provided with corresponding second receiving holes 1102. Each corresponding first receiving hole 1101 and second receiving hole 1102 is designed to accommodate the positive and negative poles of a single battery cell 20. This means that the battery cell 20 will be placed between the two holders, with its positive and negative poles located in the respective receiving holes.

[0041] Among them, the line connecting the center points of the two adjacent first receiving holes 1101 in different rows on the positive holder 111 and the first direction y form a set angle a, so as to form a first air duct 1103 on the parallel group holder 11, which is used to provide a heat dissipation channel for each battery cell 20.

[0042] It is worth noting that the angle in this article refers to the smallest positive angle formed by the intersection of two straight lines, which is called the angle between the two straight lines (or vectors), usually denoted as ∠α, and the range of the angle between the two straight lines ∠α is 0≤∠α≤90 degrees.

[0043] Among them, the set angle a specifically refers to the angle between the line connecting the center points of the two adjacent first receiving holes 1101 in different rows on the positive holder 111 and the line along the first direction y. The set angle a is greater than 0, that is, each battery cell 20 is not arranged at a right angle, but at a certain inclination angle, and specifically, each layer of battery cells 20 is arranged with a certain height difference in the first direction y, such as the height direction, and is not parallel to the first direction y.

[0044] It can be understood that each second receiving hole 1102 on the negative holder 112 will also correspond to the specific features of each first receiving hole 1101, that is, the line connecting the center points of the two adjacent second receiving holes 1102 in different rows will also form a set angle a with the first direction y.

[0045] The above scheme arranges each layer of battery cells 20 with a certain height difference in the first direction y through the battery mounting mechanism 10, so as to arrange more battery cells 20 in a limited space more closely and effectively reduce the overall height of the product, so as to be applied to any reasonable electronic equipment with a standard cabinet unit height of 1U, such as a server cabinet, a power distribution cabinet, communication equipment, etc., and the application range is wider; and since the negative electrode support 112 is detachable, when a single battery cell 20 in the battery module needs to be repaired or replaced, the operation is more convenient; arranging the battery cells 20 at a certain inclination angle helps to improve the cooling effect, reduce mechanical stress, or simplify the manufacturing process; the non-vertical arrangement of the battery cells 20 is also conducive to air circulation or fin arrangement, thereby improving the heat dissipation performance of the entire battery module; the detachable design provides the possibility of flexible configuration, and the number and arrangement of the battery cells 20 can be adjusted according to different application requirements. The battery cell 20 mounting mechanism is particularly suitable for data centers, communication base stations, industrial automation systems, medical equipment vehicles, energy storage systems, and other application occasions that require efficient management and arrangement of multiple battery units, not only supporting large-scale production and automated assembly lines, but also providing convenience for subsequent product service and support.

[0046] It is worth noting that electronic equipment with a standard cabinet unit height of 1U is widely used in data centers, communication base stations, server rooms, and other occasions. These devices are usually designed to be compact to maximize space utilization and meet industry standards for easy installation and maintenance. Here are a few common 1U height electronic equipment:

[0070] Industrial Control Computer: Embedded computers used in automation control systems sometimes also adopt 1U design.

[0071] Medical Device Interface Module: Used to connect and integrate hospital information systems and other medical devices for data transmission.

[0072] 1U height electronic devices have become an integral part of data centers and various professional environments due to their compact design and standardized mounting. They not only save valuable physical space, but also improve system scalability and ease of maintenance. With technological advancements, more and more functions are integrated into smaller spaces, making the application of 1U devices increasingly widespread.

[0073] In some embodiments, the angle a between the line connecting the centers of two adjacent first accommodation holes 1101 in different rows and the first direction y can be 0-45 degrees, and preferably 1-30 degrees. When the standard size of each cell 20 is considered, the maximum distance between the two rows of cells 20 in the first direction y, i.e., the height of the two layers of cells 20, can be kept within 37.9 mm, so that the overall height of the modular pack assembly formed by the multiple parallel group supports 11 and the cells 20 mounted thereon is within the range of 1U, and at the same time, the gap air ducts are formed between the cells 20 in the pack assembly, which is beneficial for air convection cooling.

[0074] In some embodiments, the multiple parallel group supports 11 are arranged along the second direction x, and the positive electrode support 111 of one parallel group support 11 and the negative electrode support 112 of the other parallel group support 11 are detachably connected, so as to ensure that the cells 20 can form a series or parallel circuit, while providing a flexible electrical connection scheme.

[0075] The second direction x is perpendicular to the first direction y, i.e., the multiple parallel group supports 11 are arranged along two mutually perpendicular directions to form a grid structure, so that the battery module can compactly arrange a large number of cells 20 in a plane, improving the space utilization.

[0076] The adjacent parallel group supports 11 are interconnected by detachable connection of the positive electrode support 111 and the negative electrode support 112, which not only simplifies the electrical connection between the cells 20, but also facilitates the operation of maintaining and replacing the cells 20.

[0077] It can be understood that the multiple cells 20 arranged by the parallel group support 11 form a group or a parallel group, and the positive and negative polarities of the cells 20 in the group are consistent, but opposite to those of the cells 20 in the front or rear group arranged by another adjacent parallel group support 11, and arranged side by side, and the adjacent parallel groups are connected end to end, and the multiple levels are connected in series by extending along the axis direction of the cells 20, i.e., the second direction x.

[0078] Each battery cell 20 in each parallel group is arranged with a certain height difference, fixed by a positive electrode support 111 and a negative electrode support 112, and the positive electrode support 111 and the negative electrode support 112 are detachably connected, and then each parallel group is detachably connected with each other to form a whole.

[0079] In some embodiments, the positive electrode support 111 and the negative electrode support 112 in each parallel group support 11 are specifically connected through the clamping part. The positive electrode support 111 is provided with at least one first clamping part 1111, and the negative electrode support 112 is provided with a second clamping part 1121 to cooperate with the first clamping part 1111 on the positive electrode support 111. Each first clamping part 1111 in the same parallel group support 11 is arranged to be able to accurately buckle on one second clamping part 1121, so as to ensure the stable connection between the positive electrode support 111 and the negative electrode support 112, and also facilitate disassembly and maintenance.

[0080] In some embodiments, the positive electrode support 111 is respectively provided with a first clamping part 1111 on the opposite sides along the third direction z, and the negative electrode support 112 is respectively provided with a second clamping part 1121 on the opposite sides along the third direction z. The first clamping part 1111 in the same parallel group support 11 corresponds to the second clamping part 1121 of the negative electrode support 112 one by one, so as to ensure that each first clamping part 1111 can be tightly buckled with the corresponding each second clamping part 1121 to form a stable connection, thereby realizing the connection between the positive electrode support 111 and the negative electrode support 112 in the same parallel group support 11. In addition, the clamping can be formed from the opposite sides of each parallel group support 11 to further stabilize the connection between the positive electrode support 111 and the negative electrode support 112, and to simplify the assembly process, provide the possibility of quick disassembly, and facilitate maintenance and replacement of the battery cell 20.

[0081] The third direction z, the second direction x and the first direction y are perpendicular to each other.

[0082] It can be understood that the clamping design allows the operator to quickly connect or separate the positive electrode support 111 and the negative electrode support 112, reducing the assembly time and complexity. The design of the clamping part ensures the reliable mechanical connection between the positive electrode support 111 and the negative electrode support 112, which can remain stable even under vibration or impact conditions. This connection mode supports modular battery assembly, and the size and shape of the battery module can be flexibly adjusted according to needs. When a certain specific battery cell 20 needs to be repaired or replaced, the corresponding clamping part can be loosened to easily remove or replace the target battery cell 20 without affecting other parts. The clamping part design can adapt to different sizes and specifications, suitable for various types of battery cells 20, increasing the versatility and flexibility of the system. The battery cell 20 mounting mechanism with the clamping structure significantly improves the design and application efficiency of the battery module by providing quick assembly, stable connection and easy maintenance.

[0083] In some embodiments, the number of first clamping portions 1111 in each positive electrode support 111 can be 2, 3, or 6, etc. The number of second clamping portions 1121 can also be 2, 3, or 6, etc. The structures of different first clamping portions 1111 can be the same or different, and the structures of corresponding second clamping portions 1121 can also be the same or different. Specifically, they can be in the form of matching buckles, and / or one can be a partial triangular cylinder, a partial cylinder, or a partial elliptical cylinder, etc. The other can be a matching concave or blind hole, which is not limited in the present application.

[0084] In some embodiments, the positive electrode support 111 is provided with a first positioning protrusion 1115, and the negative electrode support 112 is provided with a first positioning groove 1125 corresponding to the first positioning protrusion 1115, to ensure accurate alignment between the positive electrode support 111 and the negative electrode support 112. When the positive electrode support 111 and the negative electrode support 112 of the same group support 11 are clamped, the first positioning protrusion 1115 extends into the first positioning groove 1125, ensuring accurate alignment in the horizontal direction. At the same time, the first clamping portion 1111 passes through the first positioning protrusion 1115 and is buckled with the second clamping portion 1121, ensuring stable connection in the vertical direction.

[0085] It can be understood that the design of the first positioning protrusion 1115 and the first positioning groove 1125 ensures accurate alignment between the positive electrode support 111 and the negative electrode support 112, avoiding the risk of poor contact or short circuit due to misalignment. Through the cooperation of the first positioning protrusion 1115 and the first positioning groove 1125, combined with the buckling of the first clamping portion 1111 and the second clamping portion 1121, multi-dimensional stable connection is achieved, reducing the possibility of loosening or falling off. The positioning and clamping design allows the positive electrode support 111 and the negative electrode support 112 to be quickly connected or separated, greatly simplifying the assembly and maintenance process. The clear positioning structure reduces the possibility of errors during assembly, improving production efficiency and product quality. Accurate alignment and stable connection help maintain good electrical contact, reduce resistance loss, and improve the overall performance of the system.

[0086] In some embodiments, the positive electrode support 111 is provided with a first positioning portion 1116 on each side along the first direction y, and the negative electrode support 112 is provided with a second positioning portion 1126 on each side along the first direction y, corresponding to the first positioning portion 1116 on the positive electrode support 111, for precise alignment of the two. The first positioning portion 1116 is provided with a second positioning protrusion 1117, and the second positioning portion 1126 is provided with a second positioning protrusion 1117, which matches the second positioning protrusion 1117 on the positive electrode support 111, for receiving and fixing the second positioning protrusion 1117. When the positive electrode support 111 and the negative electrode support 112 in the same group support 11 are connected, the first positioning portion 1116 and the second positioning portion 1126 will abut each other, and the second positioning protrusion 1117 will extend into the second positioning protrusion 1117, to ensure the precise alignment of the positive electrode support 111 and the negative electrode support 112 in the horizontal direction, and to provide additional mechanical locking function to prevent accidental loosening.

[0087] It can be understood that the design of the first positioning portion 1116 and the second positioning portion 1126 ensures the precise alignment between the positive electrode support 111 and the negative electrode support 112, avoiding the risk of poor contact or short circuit due to misalignment. And because the positioning portions are arranged on both sides of the positive electrode support 111 and the negative electrode support 112, multiple points of contact are formed when connected, enhancing the overall stability of the connection. Through the cooperation of the second positioning protrusion 1117 and the second positioning protrusion 1117, plus the abutment of the first positioning portion 1116 and the second positioning portion 1126, a multi-dimensional stable connection is achieved, reducing the possibility of loosening or falling off. The positioning and clamping design allows the positive electrode support 111 and the negative electrode support 112 to be quickly connected or separated, greatly simplifying the assembly and maintenance process. The clear positioning structure reduces the possibility of errors during assembly, improving production efficiency and product quality. Precise alignment and stable connection help maintain good electrical contact, reduce resistance loss, and improve the overall performance of the system.

[0088] Further, in some embodiments, the first positioning portion 1116 on the positive electrode support 111 is provided with a positioning arc surface (not labeled in the figure) on both sides along the third direction z, and the second positioning portion 1126 on the negative electrode support 112 is also provided with a positioning arc surface on both sides along the third direction z, which is used to wrap the battery cell when the battery cell is installed in the battery mounting mechanism, to provide additional fixation and support.

[0089] It can be understood that when the positive electrode support 111 and the negative electrode support 112 in the same group support 11 are clamped, the first positioning part 1116 and the second positioning part 1126 abut, and the second positioning protrusion 1117 extends into the second positioning protrusion 1117. At the same time, the positioning arc surface wraps the battery cell, ensuring the stable position of the battery cell in the installation mechanism. Since the positioning arc surface is arranged on both sides of the first positioning part 1116 and the second positioning part 1126, multi-point contact and wrapping are formed when the battery cell is installed, enhancing the fixing effect of the battery cell and providing better mechanical protection. The design of the positioning arc surface can significantly improve the fixing effect and connection reliability of the battery cell in the battery installation mechanism. The close contact between the positioning arc surface and the battery cell helps heat conduction, and combined with appropriate heat dissipation design, the heat dissipation performance of the battery cell can be effectively improved.

[0090] In some embodiments, the positive electrode support 111 and the negative electrode support 112 are also provided with heat dissipation through holes (not labeled in the figure), wherein the heat dissipation through holes in the positive electrode support 111 are located between adjacent two first accommodating holes 1101, aiming to facilitate the transfer of heat from the battery cell to the outside air. The heat dissipation through holes in the negative electrode support 112 are located between adjacent two second accommodating holes 1102, also aiming to facilitate the transfer of heat from the battery cell to the outside air. The heat dissipation through holes on the positive electrode support 111 and the negative electrode support 112 are aligned and communicated along the second direction x, forming a continuous second air duct 1104 to ensure that the airflow can smoothly pass through the entire support structure from one side, carrying away the heat generated by the battery cell, thereby achieving high-efficiency heat dissipation effect.

[0091] It can be understood that through the design of the heat dissipation through holes, heat can be rapidly conducted from the surface of the battery cell to the support and carried away by external airflow through the second air duct 1104, avoiding local overheating phenomenon. The heat dissipation through holes are distributed between adjacent accommodating holes, ensuring that each battery cell can obtain uniform cooling effect and preventing problems caused by poor heat dissipation in certain areas. The existence of the heat dissipation through holes does not weaken the overall structural strength of the support, but can further enhance the rigidity of the support through reasonable design, such as adding support ribs, etc. The heat dissipation through hole design usually adopts stamping or mold forming process, which is easy to mass produce and quality control, reducing the manufacturing cost. Effective heat dissipation design prolongs the service life of the battery cell and other components, reduces the failure rate caused by overheating, and improves the reliability and safety of the entire system. The existence of the heat dissipation through hole provides a rapid conduction path for heat, while the second air duct 1104 optimizes the airflow path, improving the heat dissipation efficiency.

[0093] It can be understood that the design of the clamping groove 1112 and the clamping portion 1122 allows the two adjacent parallel group supports 11 to be quickly connected or separated, greatly simplifying the assembly and maintenance process. Through the cooperation of the clamping groove 1112 and the clamping portion 1122, multiple-point contact is achieved, reducing the possibility of loosening or falling off, ensuring the stability and reliability of the connection. This design allows the battery system to be flexibly expanded according to demand, and the newly added parallel group support 11 can be easily integrated with the existing structure, improving the scalability of the system. The clear position of the clamping groove 1112 and the clamping portion 1122 reduces the possibility of errors during assembly, improving production efficiency and product quality. The presence of the clamping groove 1112 and the clamping portion 1122 provides a simple and effective solution for connection, ensuring that multiple parallel group supports 11 can be quickly and stably connected together, suitable for various application scenarios and technical requirements.

[0094] Further, in some embodiments, the positive electrode support 111 in each parallel group support 11 is provided with a clamping groove 1112 on each of the opposite sides along the second direction x, and the negative electrode support 112 is provided with a clamping portion 1122 protruding along the second direction x corresponding to the position of the clamping groove 1112 on the positive electrode support 111. The clamping groove 1112 on one parallel group support 11 corresponds to the clamping portion 1122 on the parallel group support 11 adjacent to it, that is, the clamping portion 1122 can be tightly fitted into the clamping groove 1112 of the positive electrode support 111, to ensure the stable connection between the two adjacent parallel group supports 11.

[0095] Among them, the clamping portion 1122 of the negative electrode support 112 in the parallel group support 11 is clamped into the clamping groove 1112 of the positive electrode support 111 in the other parallel group support 11 adjacent to it, to realize the connection between the two adjacent parallel group supports 11, ensure the firmness of mechanical connection, and form clamping from the opposite sides of each parallel group support 11, further stabilize the connection between the two adjacent parallel group supports 11, and also allow disassembly, facilitating maintenance and replacement of the battery cell 20.

[0096] It can be understood that the design of the clamping groove 1112 and the clamping portion 1122 allows the positive electrode support 111 and the negative electrode support 112 to be quickly buckled or separated, reducing assembly time and complexity and improving production efficiency. The tightly fitted clamping groove 1112 and clamping portion 1122 provide a reliable mechanical connection that remains stable even under vibration or impact conditions, reducing the risk of loosening. The design of the clamping groove 1112 and the clamping portion 1122 can accommodate different sizes and specifications, making it suitable for various types of battery cells 20 and increasing the versatility and flexibility of the system.

[0097] The outer shape of the parallel combination support 11 formed by the connected positive electrode support 111 and negative electrode support 112 can be a rectangular parallelepiped, and the first clamping portion 1111 and the second clamping portion 1121 can be arranged on opposite sides of one pair of the parallel combination support 11, while the clamping groove 1112 and the clamping portion 1122 are arranged on opposite sides of the other pair.

[0098] In some embodiments, the number of clamping grooves 1112 in each positive electrode support 111 can be 2, 4, or 6, or any reasonable number, and the number of clamping portions 1122 can also be 2, 4, or 6, or any reasonable number; the structures of different clamping portions 1122 can be the same or different, and can be any reasonable shape such as a triangular cylinder, a partial cylinder, or a partial elliptical cylinder, and the corresponding clamping grooves 1112 are in the form of matching recesses or blind holes; and the clamping portions 1122 and the clamping grooves 1112 can also be in the form of matching buckles, which are not limited in this application.

[0099] Please continue to refer to Figure 5 , Figure 5 is Figure 1 the structure of the battery connecting piece in the parallel combination support of the backup power supply.

[0100] In some embodiments, the parallel combination support 11 also includes a battery connecting piece 113, which includes a positive electrode connecting piece 1131 and a negative electrode connecting piece 1132.

[0102] It can be understood that each positive electrode connecting part 11311 in the parallel connection support 11 and its corresponding negative electrode connecting part 11321 are respectively used to set the positive electrode and the negative electrode of one battery cell 20. In this way, the positive electrode connecting sheet 1131 can connect the positive electrodes of all battery cells 20 together, and the negative electrode connecting sheet 1132 is responsible for connecting the negative electrodes of all battery cells 20, thereby forming a unified electrical connection network.

[0103] Among them, a plurality of battery cells 20 form a group, and the positive and negative electrodes of the battery cells 20 in the group have the same direction; the positive and negative electrodes of the battery cells 20 in the group are connected together by the positive electrode connecting sheet 1131 and the negative electrode connecting sheet 1132 to form a parallel connection group; the positive and negative electrodes of adjacent battery cells 20 have the same direction, but the positive and negative electrodes of the adjacent battery cells 20 are opposite to those of the battery cells 20 in the previous group and are arranged side by side; the positive and negative electrodes of adjacent parallel connection groups are connected together by the battery connecting sheet 113 to realize multi-stage series connection.

[0104] Through the dedicated positive electrode connecting sheet 1131 and the negative electrode connecting sheet 1132, the positive and negative electrodes of all battery cells 20 can be efficiently connected, reducing the complexity and time required by the traditional wiring method. The design of the connecting sheet provides a more stable electrical connection, reduces the risk of poor contact or looseness, and improves the reliability of the entire system. When a battery cell 20 needs to be replaced or repaired, only the corresponding connecting sheet needs to be disconnected, which is simple to operate and will not affect the operation of other battery cells 20. The connection mode (such as series connection, parallel connection, or mixed connection) can be adjusted according to actual needs to meet the voltage and current requirements in different application scenarios. The separate design of the positive electrode connecting sheet 1131 and the negative electrode connecting sheet 1132 helps to prevent short circuits and increases the safety of the system. Reasonably arranged connecting sheets can help improve air flow or cooling liquid flow paths, which is beneficial to the thermal management of the entire battery module. The battery cell 20 mounting mechanism with the battery connecting sheet 113 significantly improves the design and application efficiency of the battery module by providing simplified electrical connection, improved reliability, and easy maintenance.

[0105] In some embodiments, the battery connecting sheet 113 further includes a positive electrode gasket 1133 and a negative electrode gasket 1134. The positive electrode gasket 1133 is arranged on the side of the positive electrode connecting sheet 1131 facing the negative electrode connecting sheet 1132, and is used to connect the positive electrode of each battery cell 20. The negative electrode gasket 1134 is arranged on the side of the negative electrode connecting sheet 1132 facing the positive electrode connecting sheet 1131, and is used to connect the negative electrode of each battery cell 20. In this way, the positive electrode gasket 1133 and the negative electrode gasket 1134 can be used to achieve better electrical connection between the battery cells 20 and the positive electrode connecting sheet 1131 and the negative electrode connecting sheet 1132, and reliably electrically connect the positive and negative electrodes of the battery cells 20 in each group.

[0106] In some embodiments, the battery connecting piece 113 further comprises a cascade gasket 1135 arranged between the positive connecting piece 1131 of one parallel group support 11 and the negative connecting piece 1132 of another parallel group support 11, so as to electrically connect the positive and negative poles of the adjacent two groups of battery cells 20, and realize multi-stage series connection.

[0109] In some embodiments, the battery mounting mechanism 10 further comprises a circuit board 13 connected to the other side of the plurality of parallel group supports 11 and extending along the second direction x from one end of the plurality of parallel group supports 11 to the other end thereof, so as to cover one side of the entire battery module and provide electrical connection and signal transmission functions.

[0110] In some embodiments, the circuit board 13 is connected to the positive connecting piece 1131 and the negative connecting piece 1132 through pins, welding or other connection methods, so as to ensure that the positive and / or negative poles of all battery cells 20 can be effectively connected to the circuit board 13, thereby enabling real-time monitoring of the working state (such as voltage, current, temperature, etc.) of each battery cell 20 using the circuit board 13, and transmitting data to an external management system through a communication interface.

[0111] In addition, the circuit board 13 can also integrate protection circuits, such as overcurrent protection, short circuit protection, etc., to improve the safety of the entire system.

[0116] Among them, when multiple parallel brackets 11 are used to set each battery cell 20, heat dissipation gaps are formed between each battery cell 20 extending and communicating along the second direction x. These heat dissipation gaps provide a flow path for cooling air and promote heat dissipation.

[0117] The heat dissipation fan 30 is installed on the fan mounting bracket 14 corresponding to the position of the heat dissipation gap, and can accelerate air flow through forced convection, effectively dissipating the heat generated by the battery cell 20 and keeping the working temperature of the battery module within a safe range.

[0118] It can be understood that the design of the heat dissipation gap and the heat dissipation fan 30 significantly enhances the heat dissipation performance of the battery module, helps to maintain the battery cell 20 operating at an appropriate temperature, prolongs the service life, and improves system efficiency. The heat dissipation gap extends along the second direction x and is connected, ensuring effective heat dissipation even in a compact layout, making full use of limited space. When the heat dissipation fan 30 needs to be cleaned or replaced, the fan mounting bracket 14 can be disconnected, which is simple to operate and does not affect other parts. The heat dissipation fan 30 can be adjusted according to the actual working environment (such as temperature, humidity), and is suitable for different use conditions. The battery mounting mechanism 10 with the fan mounting bracket 14 significantly improves the design and application efficiency of the battery module by providing efficient heat dissipation performance.

[0119] In some embodiments, the battery mounting mechanism 10 further includes a housing 15, which is an external packaging structure of the entire battery mounting mechanism 10, providing physical protection and environmental isolation.

[0120] In some embodiments, the set height can be specifically 37.9 mm, 40 mm or any other reasonable height not greater than 1U, which is not limited in the present application.

[0121] It can be understood that the housing 15 provides protection against external environments such as dust, water, shock, etc., prolonging the service life of the battery module.
