[0002] With the rapid development of renewable energy and the popularization of residential energy storage systems, integrated energy storage and inverter control units, as integrated devices that combine battery energy storage and inverter control, have been widely used. These devices typically house battery modules and electrical components such as inverter control boards within the same housing, placing high demands on the compactness of the internal structure, electrical safety, and heat dissipation efficiency.

[0003] Currently, battery modules in integrated energy storage inverters typically consist of multiple cells connected in series and parallel, with the cells mounted inside the casing via fixed brackets. However, existing fixed brackets are mostly simple frame structures, offering insufficient constraint on the cells. During transportation or use, the cells are prone to lateral or vertical displacement due to vibration and impact, leading to short-circuit risks. Furthermore, the bracket side panels are susceptible to outward deformation over long-term use, affecting the module's structural stability. In terms of internal heat dissipation, traditional structures often have cluttered airflow channels, high air resistance, and ineffective cooling. Additionally, the handles and ventilation holes on the side walls of the casing are usually independently designed, offering limited functionality.

[0004] Therefore, it is necessary to improve the existing battery modules and integrated energy storage and inverter units to overcome the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this application is to provide a battery module for an integrated energy storage and inverter control unit and an integrated energy storage and inverter control unit, aiming to solve the problems in existing integrated energy storage and inverter control units where the battery module fixing bracket does not fully constrain the cell positioning, leading to vibration displacement and short circuit risks that affect structural stability, as well as the problems of messy and ineffective heat dissipation airflow and single-function handle and heat dissipation holes.

The reverse control board is provided with multiple sets of heat sinks, and each set of heat sinks has a first cooling fan on its side, with the air outlet of the first cooling fan facing the corresponding heat sink; the fixing plate is provided on the side of the reverse control board, and the fixing plate is provided with a second cooling fan, with the air outlet of the second cooling fan facing the air guide cavity. The fixing plate is provided with a slot for the conductive busbar to pass through.

[0010] Preferably, the circuit breaker is a push-button type circuit breaker.

[0011] Preferably, the handle groove is a trapezoidal groove, and the opening size of the handle groove facing the outside of the box is larger than the groove wall size on the side closer to the inside of the box.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] Example 1

[0028] Reference Figures 1-3 This application discloses a battery module for an integrated energy storage and inverter device in Embodiment 1. The battery module includes several cells 11 arranged side-by-side. Each cell 11 is equipped with an explosion-proof sheet 111. Specifically, the cell 11 is a flat, rectangular, hard-shell cell, and the explosion-proof sheet 111 is a disposable, puncture-type explosion-proof sheet. The positive and negative terminals of each cell 11 are respectively located on the left and right sides of the cell 11. Terminals on the same side are electrically connected through several busbars 12, and the busbars 12 on both sides are electrically connected through conductive wire harnesses 13.

[0029] Reference Figure 2The battery cell 11 is housed within a first fixing frame 14, which is sleeved within a second fixing frame 15. A gap exists between the first fixing frame 14 and the second fixing frame 15, allowing the wire harness 13 to pass through. Specifically, both the first fixing frame 14 and the second fixing frame 15 are channel-shaped components, each having a top plate and side plates extending downwards from the front and rear sides of the top plate. The lower part of the channel-shaped component forms an opening. The top plate of the first fixing frame 14 has downwardly bent first bending portions 141 on its left and right sides, which restrict the lateral displacement of the battery cell 11.

[0030] Reference Figure 1 and Figure 2 The first fixing frame 14 and the second fixing frame 15 have a first fixing member 16 at their lower openings. The first fixing member 16 limits and fixes the battery cell 11 to the first fixing frame 14, and also limits the first fixing frame 14, on which the battery cell 11 is mounted, to be within the second fixing frame 15. Specifically, the lower part of the front and rear side plates of the second fixing frame 15 has holes along the left and right directions. The first fixing member 16 is U-shaped and also has holes on its front and rear sides. The holes at the lower part of the front and rear side plates of the second fixing frame 15 are fastened to the holes on the sides of the first fixing member 16 by bolts. The first fixing member 16 is used to limit the vertical displacement of the battery cell 11. Furthermore, the first fixing member 16 located at the edge has an upwardly bent second bending portion 161, which, together with the downwardly bent first bending portion 141 of the first fixing frame 14, limits the lateral displacement of the battery cell 11.

[0031] Reference Figure 1 and Figure 2 The second fixing frame 15 has recessed areas 151 on both its front and rear sides. Each recessed area 151 contains a plurality of first reinforcing ribs 152, which are elongated strips arranged at intervals along the left-right extension direction of the recessed area 151. Specifically, the upper side of each first reinforcing rib 152 is fixedly connected to the upper sidewall of the recessed area 151 via a welded joint, and the lower side of each first reinforcing rib 152 has a hole for fastening to the lower sidewall of the recessed area 151 with bolts. It is understood that the hole on the lower side of the first reinforcing rib 152 is located at the same position as the holes in the lower part of the front and rear side plates of the second fixing frame 15 and the holes in the two side plates of the first fixing member 16, and the three components are fastened together by the same bolt.

[0032] Reference Figure 2 and Figure 3An insulating plate 17 and a second fixing member 18 are fixed to the side of the second fixing frame 15 via a connector. The insulating plate 17 is provided with an explosion-proof tab avoidance opening 171 and a busbar avoidance opening 172. Specifically, the second fixing member 18 is a hollow wedge shape. The wedge shape is used to increase the strength of the component. The front and rear sides of the second fixing member 18 are respectively provided with holes. The two holes are used to connect with the front and rear side plates of the second fixing frame 15 by bolts. The second fixing member 18 is used to constrain the distance between the front and rear side plates of the second fixing frame 15 and suppress the outward expansion deformation of the side plates of the second fixing frame 15.

[0033] Reference Figure 2 and Figure 3 The upper part of the second fixing frame 15 is provided with a third fixing member 19, which is used to fix the second fixing frame 15 to the outer shell of the energy storage inverter integrated machine. Specifically, the third fixing member 19 is wedge-shaped, and the front side of the third fixing member 19 is provided with an L-shaped folding plate, which is used to engage with the upper side wall of the recessed area 151. The rear side of the third fixing member 19 is provided with several holes for fixing the entire battery module to the rear inner wall of the outer shell of the energy storage inverter integrated machine.

[0034] The implementation principle of a battery module for an integrated energy storage and inverter control unit according to this application embodiment is as follows: This embodiment achieves precise positioning and structural reinforcement of the cell module through a multi-layer nested fixing structure and multi-point collaborative constraints. Multiple flat, hard-shell cells are arranged side by side in the first fixing frame. The downward bending portions on the left and right sides of the top plate of the first fixing frame and the upward bending portions of the first fixing members at the edge cooperate to restrict the lateral displacement of the cells. The first fixing members simultaneously constrain the vertical displacement of the cells from the lower part of the opening and confine the entire first fixing frame within the second fixing frame, forming an omnidirectional limiting. The recessed areas of the front and rear side plates of the second fixing frame and the spaced first reinforcing ribs improve lateral stiffness. The holes on the lower side of the first reinforcing ribs, the holes on the lower part of the side plates of the second fixing frame, and the holes of the first fixing members are connected by the same bolt, simplifying assembly and enhancing overall integrity. The hollow wedge-shaped second fixing members constrain the distance between the front and rear side plates, suppress the outward deformation of the side plates, and ensure dimensional stability during long-term use. The explosion-proof sheet and the busbar avoidance opening on the insulating plate achieve electrical isolation and safe pressure relief. The third fastener engages with the upper wall of the recessed area via an L-shaped folding plate, and then secures the module to the inner rear wall of the outer casing through a rear hole, achieving modular mounting. The overall structure balances cell positioning, insulation protection, rigidity enhancement, and convenient installation, ensuring the reliability and safety of the battery module under vibration and thermal runaway scenarios.

[0035] Example 2

[0036] Reference Figures 4-8Embodiment 2 of this application discloses an integrated energy storage and inverter control unit, including a battery module 1 as described in Embodiment 1, and a housing 2. The back of the housing 2 is provided with a wall-mounted mounting bracket 3, and the interior of the housing 2 accommodates an inverter control board 4 and a fixing plate 5.

[0037] Reference Figure 4 The outer shell 2 is assembled from a cover 21 and a housing 22 via connectors. The cover 21 is provided with a human-machine interaction area 211. Specifically, the human-machine interaction area 211 is provided with an LCD display screen, an operation lever or button, and a light. The LCD display screen is used to display the real-time operating status of the battery module 1 and the reverse control board 4. The operation lever or button is used for menu switching. The light is used to provide illumination in the dark.

[0038] Reference Figure 5 and Figure 6 The sidewall of the housing 22 is provided with a switch group 221, a circuit breaker 222, a first heat dissipation hole 223, and an external interface area 224. Specifically, the switch group 221 includes three switches: a power switch, a reverse control board switch, and a lighting switch; the external interface area 224 includes a power interface area and a communication interface area. The power interface area is used for PV photovoltaic input and AC input / output, and the communication interface area is provided with a Type-B communication port, a CAN / RS485 communication port, a debug port, and dry contacts. In a preferred embodiment, the circuit breaker 222 is a push-button circuit breaker. The first heat dissipation hole 223 is a regular hexagonal hole, symmetrically arranged on the left and right sides of the housing 22. The air inside the housing 2 can exchange air with the outside through the first heat dissipation hole 223 for heat dissipation inside the housing.

[0039] Reference Figure 5 and Figure 6 The sidewall of the housing 22 is further provided with an inwardly recessed handle groove 225 and battery positive and negative terminal grooves 226. The handle groove 225 has a groove wall, on which a second heat dissipation hole 227 is formed. The positive and negative terminals of the battery module 1 are disposed within the battery positive and negative terminal grooves 226. In a preferred embodiment, the handle groove 225 is a trapezoidal groove, and the opening size of the handle groove facing the outside of the housing is larger than the groove wall size on the side closer to the inside of the housing, thus widening the outer opening for easy gripping during transport. Of course, in other embodiments, the handle groove can also be set to a rectangular or other shapes. The handle groove 225 serves as both a gripping position and integrates the second heat dissipation hole 227 in its groove wall, combining transport and heat dissipation / ventilation functions. Specifically, the shape of the second heat dissipation hole 227 is the same as the shape of the first heat dissipation hole 223.

[0040] Reference Figure 5 and Figure 6The wall-mounted mounting bracket 3 is fixed to the rear wall of the housing 22 via connectors. Specifically, the rear wall of the housing 22 has a plurality of mounting posts 228 evenly arranged along the left-right direction. The mounting posts 228 protrude from the rear inner wall of the housing 22 and are hollow with threaded holes inside. The wall-mounted mounting bracket 3 has mounting holes evenly arranged along the left-right direction. Screws pass through the mounting holes and are screwed into the threaded holes of the mounting posts 228 to lock and fix the wall-mounted mounting bracket 3 to the rear wall of the housing 22. The wall-mounted mounting bracket 3 is used to fix the entire energy storage and inverter integrated machine to the wall. Specifically, the wall-mounted mounting bracket 3 is a one-piece multi-segment bent sheet metal part, arranged along the length of the housing. The upper and lower bent parts have holes for connecting to the wall with expansion bolts, etc., and the middle fixing part is used to connect to the housing 22. The long, narrow wall-mounted bracket can distribute the weight of the entire unit, improve the uniformity of stress during wall mounting, and enhance the structural stability of the entire unit after wall mounting.

[0041] Reference Figure 7 and Figure 8 The front of the reverse control plate 4 is provided with an air guide plate 41. The air guide plate 41 is U-shaped and forms an air guide cavity. The reverse control plate 4 is arranged inside the air guide cavity. The air guide plate 41 has several holes for fixing the air guide plate 41 to the inner wall of the cover 21. Of course, in other embodiments, the air guide plate 41 can also be fixed to the inner wall of the cover 21 or the shell 22 by L-shaped fasteners. The reverse control plate 4 is provided with multiple sets of heat sinks 42. Each set of heat sinks 42 has a first cooling fan 43 on its side. The air outlet of the first cooling fan 43 is directed towards the corresponding heat sink 42. Specifically, the reverse control plate 4 is provided with three sets of heat sinks 42, and correspondingly, there are three first cooling fans 43. The cooling fans 43 are mounted on the plate body of the reverse control plate by L-shaped mounting brackets.

[0042] Reference Figure 7 and Figure 8 The fixing plate 5 is located on the side of the reverse control plate 4. A second cooling fan 51 is mounted on the fixing plate 5, and its position corresponds to the position of the first heat dissipation hole, facilitating air exchange and heat dissipation. The exhaust side of the second cooling fan 51 faces the air guide cavity. The air guide plate 41 is used to concentrate the airflow output by the second cooling fan 51 onto the reverse control plate 4, and also provides protection and isolation for the reverse control plate 4. Specifically, the fixing plate 5 has holes for fixing the second cooling fan 51, and a bending portion with holes for fixing the fixing plate 5 to the outer casing.

[0043] Reference Figure 7 and Figure 8 The fixing plate 5 has a slot 52 for the conductive busbar to pass through. Specifically, a second cooling fan 51 is fixed on the upper and lower sides of the fixing plate, and a slot 52 is provided between the two second cooling fans 51 for the conductive busbar used to electrically connect the inverter board to the external interface or battery module 1 to pass through. In a preferred embodiment, a first cooling fan 43 is provided on the side of the slot 52. This first cooling fan 43 corresponds to a set of heat sinks 42. This first cooling fan 43 also has an air guide plate. The length, width and height of this air guide plate are smaller than the aforementioned air guide plate 41. This air guide plate is used to concentrate the airflow output by this first cooling fan 43 onto the corresponding set of heat sinks 42.

[0044] Reference Figure 5 and Figure 8 There is a certain space between the left side of the fixing plate 5 and the left side of the cell module 1 and the left inner side wall of the housing 22. The space is used to connect the conductive busbar and the positive and negative terminals of the cell 11 to various electrical interfaces on the side wall of the housing 22 through conductive wire harnesses, and the space helps the cell module 1 and the reverse control board 4 to dissipate heat.

[0045] Reference Figure 7 The rear inner wall of the housing 22 is welded with a second reinforcing rib 229, which has multiple perforated through holes. Specifically, the second reinforcing rib 229 is a long strip of sheet metal reinforcing rib that extends along the length of the rear inner wall of the housing, i.e., along the left and right sides, and its position corresponds to the position of the wall-mounted mounting bracket 3. The second reinforcing rib 229 has several perforated grooves, which improves the overall bending stiffness of the housing sidewall, suppresses housing deformation, and reduces the weight of the reinforcing rib itself, thus reducing material consumption.

[0046] The implementation principle of the energy storage and inverter integrated machine in this embodiment is as follows: The battery module, inverter board, and heat dissipation system are integrated into the outer casing, and the entire machine is stably fixed using a wall-mounted bracket. The outer casing is assembled from a cover and a housing. The human-machine interface area on the cover provides operation monitoring and access, while the side wall switch group, circuit breaker, and external interface enable power on / off, protection, and external communication. The trapezoidal handle groove serves both as a handle for handling and as a secondary heat dissipation and ventilation feature, and the battery positive and negative terminal grooves contain built-in terminals for easy wiring. The wall-mounted bracket is fixed to the rear wall of the housing via mounting columns. Its multi-segment bending structure distributes the weight of the entire machine along its length, improving the uniformity of stress on the wall-mounted bracket. The second reinforcing rib welded to the corresponding position on the inner rear wall of the housing uses a hollow design to enhance bending stiffness and reduce weight, forming a synergistic load-bearing structure with the wall-mounted bracket to suppress wall-mounted deformation. Internal cooling employs a zoned air-cooling system: multiple heatsinks on the inverter board, coupled with a primary cooling fan for direct forced convection, and a U-shaped air guide plate concentrates airflow onto the heatsink surface, improving heat exchange efficiency; a secondary cooling fan on the mounting plate introduces cool outside air through the primary ventilation holes, and the air guide plate concentrates the airflow onto the core area of ​​the inverter board, while also providing protection and isolation. A slotted power supply connector on the mounting plate passes through, optimizing cable routing. The entire unit is structurally stable, provides ample cooling, and is easy to operate when wall-mounted.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
