[0001] This utility model relates to the field of energy storage technology, and in particular to an energy storage battery module. Background Technology

[0002] With the rapid development of new energy technologies, large-scale energy storage systems are playing an increasingly important role in areas such as power peak shaving and renewable energy grid connection. As the core equipment of an energy storage system, the energy storage battery module typically contains multiple battery packs to achieve large-capacity energy storage. In existing technologies, the connection between the battery packs and the battery management system (BMS) slave board is usually achieved using screws. During slave board installation, the mounting holes on the slave board need to be aligned with the corresponding mounting holes on the connector. Due to the large number of battery packs within the energy storage battery module, aligning them one by one is time-consuming. Utility Model Content

Detailed Implementation

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-4As shown, the energy storage battery module provided in this embodiment includes a housing 100 and multiple battery packs 200 disposed within the housing 100. The battery packs 200 are arranged along the length direction within the housing 100. A connector 210 is provided on the top of the battery pack 200, and a protrusion 211 is provided on the connector 210. The energy storage battery module also includes a slave plate 300 electrically connected to the connector 210. A through hole 310 is provided through the slave plate 300, and the protrusion 211 is inserted into the through hole 310.

[0023] In this embodiment, the battery packs 200 are arranged and installed in a modular manner along the length of the housing 100. Each battery pack 200 has a connector 210 on its top. The connector 210 has a protrusion 211. The protrusion 211 is designed to achieve a quick and accurate connection with the slave plate 300. Specifically, the slave plate 300 has a through hole 310 that mates with the protrusion 211. With this design, during installation, simply aligning the through hole 310 of the slave plate 300 with the protrusion 211 of the connector 210 allows for quick docking between the battery pack 200 and the slave plate 300. This fixed protrusion 211 guides the installation position of the slave plate 300, ensuring accurate connection and facilitating subsequent secondary fixing of the slave plate 300 using screws or other fasteners.

[0024] In this embodiment, the top of the battery pack 200 refers to the side facing the opening direction of the housing 100. Specifically, if the opening side of the housing 100 is defined as the top, then when the battery pack 200 is installed inside the housing 100, its end face facing the top of the housing 100 is the top of the battery pack 200. The connector 210 is disposed on this top of the battery pack 200 to facilitate installation, inspection, and maintenance operations after the housing 100 is opened.

[0025] Connector 210 is located on top of battery pack 200 and is used to establish an electrical connection between battery pack 200 and slave board 300. Slave board 300 can obtain the real-time status of battery pack 200 by cooperating with connector 210.

[0026] In this embodiment, the energy storage battery module achieves a fast and accurate connection between the battery pack 200 and the slave board 300 through the design of the above-described connection structure, thereby improving the assembly efficiency of the energy storage battery module. This connection method effectively solves the problems of inconvenient connection and inaccurate positioning between the battery pack 200 and the slave board 300 in traditional energy storage battery modules.

[0027] In one embodiment, the protrusion 211 is a columnar structure with unequal major and minor axes, and the shape of the through hole 310 is adapted to the protrusion 211.

[0028] In this embodiment, as Figure 3As shown, the protrusion 211 on the connector 210 is a columnar structure with unequal major and minor axes. Specifically, the vertical cross-section of the protrusion 211 (i.e., the cross-section perpendicular to the insertion direction) is elliptical. Correspondingly, the shape of the through hole 310 on the plate 300 is adapted to the elliptical cross-section of the protrusion 211, that is, the vertical cross-section of the through hole 310 is also elliptical.

[0029] This structural design, with its unequal major and minor axes, provides a clear directionality, effectively preventing misalignment during installation. Because the major and minor axes of the columnar structure are of different dimensions, successful insertion is only possible when the protrusion 211 is perfectly aligned with the through hole 310. This design effectively avoids potential directional errors during installation.

[0030] Furthermore, the columnar structure design not only ensures the correct insertion direction but also guarantees the precise relative position between the connector 210 and the slave board 300. When the protrusion 211 is fully inserted into the through hole 310, the fit between the two effectively prevents relative rotation, ensuring connection stability.

[0031] In other embodiments, the protrusion 211 is a hexagonal columnar structure (not shown in the figures), with a regular hexagonal vertical cross-section. Correspondingly, the through hole 310 on the plate 300 is designed as a hexagonal through hole. This structural design also enables quick docking between the plate 300 and the protrusion 211.

[0032] In one embodiment, a through hole 310 is provided in the middle of the plate 300.

[0033] In this embodiment, as Figure 3 As shown, the through hole 310, which extends through the plate 300, is located in the center of the plate 300. Specifically, the plate 300 can be roughly divided into a central region and an edge region, and the through hole 310 is located in the central region. In addition to the through hole 310, circuit traces also need to be arranged on the plate 300. The placement of the through hole 310 in the central region provides sufficient space for the circuit traces in the edge region. Moreover, this centrally located design can reduce positioning deviations during installation and improve assembly efficiency.

[0034] In one specific embodiment, the substrate 300 is a cuboid-shaped circuit board with opposing front and rear surfaces. A through-hole 310 is disposed at the center of the substrate 300, that is, penetrating both the front and rear surfaces of the substrate 300. The dimensions of the substrate 300 in the length and height directions are significantly larger than its thickness direction dimension.

[0035] In one embodiment, a fixing plate 400 is provided between two adjacent slave plates 300.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, two adjacent slave plates 300 arranged along the length of the housing 100 are connected and fixed by a fixing plate 400. The fixing plate 400 is made of a flexible material with bends to maintain a reliable connection between adjacent slave plates 300, preventing the slave plates 300 from being affected by stress. Specifically, the fixing plate 400 includes two connected wing plates 401. One wing plate 401 is fixed to the bottom edge of the upper slave plate 300, and the other wing plate 401 is fixed to the top edge of the lower slave plate 300. The wing plates 401 can be fixedly connected to the slave plates 300 by fasteners such as screws and rivets. When installing the slave plates 300, two or more slave plates 300 can be pre-connected into a whole using the fixing plate 400, and then positioned on top of the corresponding battery pack 200 in one go. This assembly method can improve the efficiency of installing the slave plates 300.

[0037] In one embodiment, a partition 700 is provided between two adjacent battery packs 200 along the length direction of the housing 100, and a ventilation hole 710 is provided through the partition 700 along the width direction.

[0038] In this embodiment, as Figure 3 As shown, the partition 700 is connected to the inner wall of the housing 100, serving to support and limit the battery pack 200 and isolate adjacent battery packs 200. The ventilation hole 710 is arranged through the width of the partition 700, forming a vertical ventilation channel, which is conducive to the natural flow of hot air around the battery pack 200, thereby helping to dissipate heat inside the housing 100.

[0039] In one embodiment, a wire harness fastener 720 is provided on the top of the partition 700.

[0040] In this embodiment, as Figure 4 As shown, the wiring harness fastener 720 is used to secure and organize the wiring within the housing 100. This design, with the wiring harness fastener 720 positioned on top of the partition 700, solves the problem of messy wiring inside the battery module. Furthermore, since the partition 700 serves as a support structure between adjacent battery packs 200, placing the wiring harness fastener 720 on its top makes full use of the existing structural space.

[0041] In one specific embodiment, the wire harness fixing component 720 adopts a C-shaped snap-fit ​​structure with a C-shaped opening. The inner cavity size of the C-shaped opening is adapted to the outer diameter of the wire harness to be fixed, and the opening width is slightly smaller than the wire harness diameter. The wire harness is fixed by utilizing the elastic deformation of the material. Here, the wire harness to be fixed refers to multiple wire harnesses gathered together.

[0042] The operator can insert the wire harness into the wire harness retainer 720 from the C-shaped opening. During the insertion process, the wire harness retainer 720 will deform to facilitate the insertion of the wire harness; after the wire harness is fully inserted into the inner cavity of the wire harness retainer 720, the wire harness retainer 720 will spring back and firmly fix the wire harness in the inner cavity.

[0043] In one embodiment, the housing 100 is provided with two battery compartments 110 spaced apart from each other, and the battery pack 200 is respectively disposed in the two battery compartments 110.

[0044] In this embodiment, as Figure 1 and Figure 2 As shown, the internal space of the housing 100 is divided into two battery compartments 110 spaced apart on the left and right. The two battery compartments 110 adopt a left-right compartment design, and a heat dissipation channel 120 is formed between the two battery compartments 110. Multiple battery packs 200 are arranged along the length direction in each battery compartment 110.

[0045] The heat dissipation channel 120 between the two battery compartments 110 forms a hot air flow channel. When the battery pack 200 generates heat during operation, the heat can be dissipated to the outside in a timely manner through the heat dissipation channel 120, preventing heat from accumulating in a localized area.

[0046] In one embodiment, an exhaust fan 800 is provided at the front end of the housing 100, with the front end of the motor of the exhaust fan 800 facing the gap between the two battery compartments 110.

[0047] In this embodiment, as Figure 1 and Figure 2 As shown, to further improve the heat dissipation of the energy storage battery module, an exhaust fan 800 is installed at the front end of the housing 100. The front end of the motor of the exhaust fan 800 (not shown in the attached diagram) faces the heat dissipation channel 120 between the two battery compartments 110, so as to accelerate the exhaust of hot air inside the housing 100 through the suction action of the exhaust fan 800. Here, the front end of the motor is the end where the motor output shaft is located. Specifically, the exhaust fan 800 is located in the middle area of ​​the front end of the housing 100, directly facing the heat dissipation channel 120 between the two battery compartments 110. This arrangement makes full use of the intermediate airflow effect and also facilitates the installation and maintenance of the exhaust fan 800.

[0048] In one embodiment, the energy storage battery module further includes a main board 500 disposed at the front end of the housing 100, the main board 500 being electrically connected to the slave board 300 via a communication line assembly 600.

[0049] In this embodiment, as Figure 1As shown, the motherboard 500 establishes a communication connection with each slave board 300 installed inside the enclosure 100 via the communication cable assembly 600. Specifically, battery status information (such as voltage, temperature, and other parameters) collected by the slave boards 300 is transmitted to the motherboard 500 via the communication cable assembly 600.

[0050] In summary, this embodiment features a protrusion 211 of a specific shape on the connector 210 and corresponding through holes 310 on the slave plate 300. This design ensures quick and accurate docking between the battery pack 200 and the slave plate 300. Simultaneously, this structure prevents relative rotation after connection, improving connection stability. This embodiment uses a fixed plate 400 to connect adjacent slave plates 300, effectively maintaining the relative positional stability between adjacent slave plates 300. Another advantage of this design is that multiple slave plates 300 can be pre-assembled into a component, thereby improving overall installation efficiency and reducing the installation and positioning time of a single slave plate 300. Furthermore, the existing structural space is fully utilized by providing a wire harness fixing member 720 on the top of the partition 700. This embodiment's energy storage battery module adopts a left-right compartment design, forming a heat dissipation channel 120 between the two battery compartments 110. This design fully utilizes the central airflow effect, avoiding localized heat accumulation and creating an effective airflow path.

Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
