Description

Technical Field

[0001] This application belongs to the field of energy storage equipment technology, and more specifically, relates to an energy storage battery and a home energy storage integrated machine. Background Technology

[0002] A home energy storage unit is an advanced energy storage device that releases stored energy during peak electricity demand or power outages, ensuring uninterrupted power supply for users. To accommodate different user installation needs and usage habits, home energy storage units are typically composed of multiple stacked and connected energy storage battery modules. This modular design not only simplifies the installation process but also allows users to flexibly increase or decrease the number of energy storage batteries according to actual needs, thereby adjusting the overall energy storage capacity.

[0003] Each energy storage module consists of a robust housing and an embedded battery module. The battery module is connected to external circuitry via wiring, and adjacent energy storage modules are also interconnected via wiring. For ease of installation, maintenance, and servicing, each battery module has a removable panel on the side of its housing. This design allows technicians easy access to the internal components for necessary operations.

[0004] However, in practice, technicians need to completely remove the side panels of the two adjacent battery module housings to expose the connecting wires. While this process is designed for convenience, it proves somewhat cumbersome in actual operation. Utility Model Content

[0005] The purpose of this application is to provide an energy storage battery and an integrated home energy storage unit to solve the problem that the installation and maintenance of energy storage batteries in the prior art requires the complete removal of the side panels, which results in poor convenience.

[0006] To achieve the above objectives, in a first aspect, this application provides an energy storage battery, including at least two battery modules stacked along a first direction; each battery module includes a housing, a side cover, and a battery module; the housing has an installation chamber; the side cover includes a plate and a maintenance plate; the plate is connected to one side of the housing in a second direction, which is perpendicular to the first direction, and a portion of the plate is spaced apart from the housing to form a wiring channel that runs through the first direction; the wiring channels in two adjacent battery modules are connected; the plate has an inspection hole connecting the wiring channel to an external space; the maintenance plate is movably connected to the plate and covers the inspection hole; the battery module is disposed in the installation chamber, and the battery module has connecting wires that extend into the wiring channel.

[0007] In some embodiments of the first aspect, one of the plate body and the inspection plate is provided with a first locking structure, and the other is provided with a second locking structure, wherein the first locking structure and the second locking structure are detachably engaged.

[0008] In some embodiments of the first aspect, the first locking structure includes a first support member and a locking rod slidably connected to the first support member; the second locking structure includes a second support member, the second support member having a lock hole, and the locking rod having a locking position at least partially inserted into the lock hole and an unlocking position disengaged from the lock hole.

[0009] In some embodiments of the first aspect, the first locking structure further includes a first elastic element disposed on the first support member for providing elastic force to the locking rod toward the lock hole.

[0010] In some embodiments of the first aspect, the end face of the locking rod facing the lock hole is a spherical or conical surface.

[0011] In some embodiments of the first aspect, the second locking structure further includes an unlocking lever slidably disposed within the keyhole, capable of pushing the locking lever in the locked position out of the keyhole, so that the locking lever moves from the locked position to the unlocked position.

[0012] In some embodiments of the first aspect, the second locking structure further includes a second elastic element disposed on the second support body for providing elastic force to the unlocking rod in a direction opposite to the locking rod.

[0013] In some embodiments of the first aspect, the side cover further includes a pivot, through which the inspection plate is rotatably connected to the plate body.

[0014] In some embodiments of the first aspect, a third elastic member is provided between the inspection plate and the plate body, the third elastic member being used to provide elastic force to the inspection plate in the direction opposite to the wiring channel.

[0015] Secondly, this application provides a home energy storage unit, including an inverter and an energy storage battery as described in the first aspect and any of its optional embodiments, wherein the inverter is connected to the energy storage battery.

[0016] The beneficial effects of the energy storage battery and integrated home energy storage unit provided in this application are as follows: Compared with the prior art, when circuit testing or wire connection operations are required, technicians only need to open a single inspection board to perform overall maintenance on the connecting wires of the multi-layer stacked battery modules through the through wiring channel. This avoids the cumbersome operation of having to disassemble the side panels layer by layer in the traditional solution, which can significantly improve the operational efficiency of energy storage battery inspection and maintenance, and also reduce the risk of loss or damage of parts during the maintenance process by disassembling parts.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] In a first aspect, embodiments of this application provide an energy storage battery 100, referring to... Figures 1-6The energy storage battery 100 includes a housing 110, a side cover 120, and a battery module 130. The housing 110 has an installation chamber 1101, and the battery module 130 is disposed within the installation chamber 1101. The side cover 120 includes a plate 121 and a maintenance plate 122. The plate 121 is connected to the outer wall of the housing 110, and a portion of the plate 121 is spaced apart from the outer wall of the housing 110 to form a through-type maintenance channel. The battery module 130 has a connecting wire 131 extending into a wiring channel 1211. The plate 121 may also have a maintenance hole 1212 connecting the wiring channel 1211 to the external space. The maintenance plate 122 is movably connected to the plate 121 and covers the maintenance hole 1212.

[0034] Among them, reference Figure 2 The housing 110 is a hollow shell structure, forming an installation chamber 1101 inside to accommodate the battery module 130 and its auxiliary components. The housing 110 is made of high-strength alloy or plastic, and its shape can be designed as a cuboid, cylinder, or other suitable shape according to actual needs. In this embodiment, the housing 110 has a cuboid structure and is formed by splicing multiple plates to facilitate the installation and maintenance of the battery module 130.

[0035] Reference Figure 3 The side cover 120 can be connected to any side of the housing 110. In this embodiment, the side cover 120 is connected to one side of the housing 110 along its length. The plate 121 is a plate-shaped structure that matches the shape of the side of the housing 110. Two vertically extending protrusions 1213 are provided on the side of the plate 121 facing the housing 110. The protrusions 1213 abut against the outer wall surface of the housing 110, so that the portion of the plate 121 between the two protrusions 1213 is spaced from the outer wall surface of the housing 110, thereby forming a through wiring channel 1211. In this embodiment, the extension direction of the protrusions 1213 is vertical. The two protrusions 1213 are located at both ends of the plate 121 in the width direction, so that the wiring channel 1211 formed between the plate 121 and the outer wall surface of the housing 110 passes through the entire energy storage battery 100 in the vertical direction.

[0036] A connecting wire 131 is led out from the battery module 130 to connect the battery module 130 to other battery modules 130 or external circuits to achieve the purpose of power transmission. The side wall of the housing 110 near the wiring channel 1211 may have a through hole connecting the wiring channel 1211 and the mounting chamber 1101, so that the connecting wire 131 can extend into the wiring channel 1211 through the through hole.

[0037] It is understood that the energy storage battery 100 in this embodiment can be used individually or in combination. When the energy storage battery 100 is used individually, an inverter 200 can be installed on one side of the energy storage battery 100. When the energy storage batteries 100 are used in combination, multiple energy storage batteries 100 can be stacked and assembled in a vertical or other direction to form a battery module, and the inverter 200 is installed on the top or one side of the battery module.

[0038] Reference Figure 5 and Figure 6 When multiple batteries are stacked and assembled, the wiring channels 1211 of adjacent energy storage batteries 100 are interconnected. This allows for unified wiring of the connecting wires 131 of two adjacent energy storage batteries 100 within the interconnected wiring channels 1211, simplifying circuit connections and improving system stability and maintenance efficiency. Similarly, the wires 131 on the inverter 200 installed on the energy storage battery 100 can also be introduced into the wiring channels 1211 and connected to the connecting wires 131 of the battery module 130, enabling circuit conduction and facilitating the connection and installation of the wires 131.

[0039] Reference Figure 3 and Figure 4 The inspection hole 1212 is a through-hole structure provided on the plate 121. Its shape can be arbitrary. In this embodiment, the inspection hole 1212 is a rectangular hole and is provided at the top of the plate 121. The inspection plate 122 is a plate-shaped structure whose shape matches the inspection hole 1212. The area of ​​the inspection plate 122 should be at least equal to the area of ​​the inspection hole 1212 so as to completely cover the inspection hole 1212. The number and position of the inspection holes 1212 on the plate 121 can be arbitrary. In this embodiment, there are two inspection holes 1212, which are respectively provided at the top and bottom ends of the plate 121. The inspection holes 1212 are open. The shape of the inspection plate 122 is the same as that of the inspection hole 1212 and is embedded in the inspection hole 1212 to completely seal the inspection hole 1212 and make the inspection plate 122 flush with the surface of the plate 121, thereby improving the overall appearance of the energy storage battery 100.

[0040] The number of inspection plates 122 can be the same as the number of inspection holes 1212. In this embodiment, there are two inspection plates 122, corresponding to the inspection holes 1212 at the upper and lower ends, respectively. The inspection plates 122 can be detachably connected to the plate body 121 by clips or bolts, so that the inspection holes 1212 can be opened by removing the inspection plates 122 from the plate body 121. The inspection plates 122 can also be rotatably connected to the plate body 121 by hinges or other means, so that the inspection holes 1212 can be opened by rotating the inspection plates 122 around the hinge point. In this embodiment, the side cover plate 120 also includes a rotating shaft 123. The inspection plates 122 are rotatably connected to the plate body 121 through the rotating shaft 123. The rotating shaft 123 is located on one edge of the inspection plate 122. The inspection plates 122 can rotate 90 degrees around the rotating shaft 123. The inspection holes 1212 can be opened by turning the inspection plates 122 in the direction away from the maintenance channel.

[0041] It is understandable that when the wires 131 are connected between two adjacent batteries, the connector of the wires 131 is generally connected near the cavity of the wiring channel 1211. Therefore, the inspection hole 1212 located at the end of the plate 121 is directly opposite the connection position of the wires 131, which makes it convenient for maintenance personnel to directly inspect and operate the wires 131 connection through the inspection hole 1212. In addition, it is also possible to open two adjacent inspection holes 1212 at the same time, expanding the operating space for maintenance personnel.

[0042] Reference Figure 4 Furthermore, one of the plate 121 and the inspection plate 122 is provided with a first locking structure 140, and the other is provided with a second locking structure 150. The first locking structure 140 and the second locking structure 150 are detachably engaged. The first locking structure 140 and the second locking structure 150 can be an interlocking snap-fit ​​or threaded connection, or a magnetic adsorption structure. This fixes the position of the inspection plate 122 when the inspection hole 1212 is closed, preventing the inspection plate 122 from opening on its own due to external force and improving safety.

[0043] Reference Figure 7 and Figure 8 In this embodiment, the first locking structure 140 is installed on the side wall of the inspection plate 122 facing the wiring channel 1211. The first locking structure 140 includes a first support member 141 and a locking rod 142 slidably connected to the first support member 141.

[0044] Specifically, the first support member 141 is a protrusion whose shape matches the side wall of the inspection plate 122. The first support member 141 is fixed to the side wall of the inspection plate 122 by a snap-fit ​​or threaded connection. The locking rod 142 is a cylindrical or other rod-shaped structure. The first support member 141 may have a mounting hole 1411 that matches the shape of the locking rod 142, and the locking rod 142 can slide through the mounting hole 1411. Furthermore, the first support member 141 may also have a limiting hole, which communicates with the mounting hole 1411. The locking rod 142 is provided with a limiting pin, which is threaded onto the locking rod 142 and can slide through the limiting hole. The locking pin's engagement within the limiting hole prevents the locking rod 142 from coming out of the mounting hole 1411.

[0045] Reference Figure 7 and Figure 8 In this embodiment, the second locking structure 150 is installed on the side wall of the plate 121 facing the wiring channel 1211. The second locking structure 150 includes a second support member 151, which has a lock hole 1511. The locking rod 142 has a locking position that is at least partially inserted into the lock hole 1511 and an unlocking position that is disengaged from the lock hole 1511.

[0046] The second support member 151 is a block-shaped structure disposed on the side wall of the plate 121 facing the wiring channel 1211. The locking hole 1511 on the second support member 151 matches the shape of the locking rod 142. The locking hole 1511 is provided through the thickness direction of the second support member 151 so that the locking rod 142 can be inserted into the locking hole 1511 to lock the inspection plate 122 to the plate 121. In the locked state, the locking rod 142 is partially or completely inserted into the locking hole 1511. At this time, an interference fit or clearance fit is formed between the locking rod 142 and the locking hole 1511 to fix the inspection plate 122 to the plate 121. When it is necessary to open the inspection plate 122, the locking rod 142 can be manually pushed to disengage from the locking hole 1511 and enter the unlocked position. At this time, the inspection plate 122 can rotate around the rotating shaft 123.

[0047] Furthermore, the first locking structure 140 may also include a first elastic element 143, which is disposed on the first support member 141 and is used to provide elastic force to the locking rod 142 in the direction of the lock hole 1511. Under the action of the first elastic element 143, the locking rod 142 tends to move in the direction of the lock hole 1511, thereby facilitating the automatic insertion of the locking rod 142 into the lock hole 1511 and realizing the rapid locking of the inspection plate 122 and the plate body 121. The first elastic element 143 may be a spring, sheet metal, or other elastic element, with one end connected to the first support member 141 and the other end connected to the locking rod 142 to apply a continuous elastic force to the locking rod 142.

[0048] In this embodiment, the first elastic element 143 is a helical spring. The helical spring is disposed inside the mounting hole 1411. For example, the mounting hole 1411 is a stepped hole, and a portion of the inner wall surface of the mounting hole 1411 forms a receiving space with the locking rod 142 at intervals. The helical spring is placed in the receiving space and sleeved on the locking rod 142. One end of the helical spring abuts against the end of the locking rod 142, and the other end abuts against the inner wall of the first support member 141, so as to apply an elastic force to the locking rod 142 in the direction of the lock hole 1511.

[0049] Furthermore, the end face of the locking rod 142 facing the lock hole 1511 is a spherical or conical surface. During the rotation of the inspection plate 122 into the inspection hole 1212, when the end of the locking rod 142 located outside the mounting hole 1411 contacts the corresponding side wall of the plate body 121, the arc or inclined surface drives the locking rod 142 to gradually move towards the inside of the mounting hole 1411 until the locking rod 142 is fully inserted into the mounting hole 1411. As the inspection plate 122 continues to rotate, the locking rod 142 gradually extends out of the mounting hole 1411 under the elastic force of the first elastic element 143 until the end of the locking rod 142 is inserted into the lock hole 1511, thus achieving automatic locking between the inspection plate 122 and the plate body 121, simplifying user operation and improving efficiency.

[0050] In some embodiments, the second locking structure 150 further includes an unlocking rod 152, which is slidably disposed within the lock hole 1511. The unlocking rod 152 can push the locking rod 142, which is in the locked position, out of the lock hole 1511, thereby moving the locking rod 142 from the locked position to the unlocked position. Specifically, the unlocking rod 152 is a rod-shaped structure whose length is adapted to the depth of the lock hole 1511. One end of the unlocking rod 152 can extend outside the lock hole 1511 for easy operation by a technician. The other end of the unlocking rod 152 can be provided with a driving block 1521, the shape of which is adapted to the locking rod 142. When the unlocking rod 152 moves, the driving block 1521 can push the locking rod 142, causing the locking rod 142 to disengage from the lock hole 1511.

[0051] Furthermore, the second locking structure 150 also includes a second elastic element 153, which is disposed on the second support member 151 and provides a spring force to the unlocking rod 152 in the direction away from the lock hole 1511. Under the action of the second elastic element 153, the unlocking rod 152 tends to move in the direction away from the lock hole 1511, thereby keeping the unlocking rod 152 in a non-working state and preventing accidental unlocking of the locking rod 142. When unlocking is required, a technician can press the end of the unlocking rod 152 extending out of the lock hole 1511 to overcome the spring force of the second elastic element 153, causing the unlocking rod 152 to move and push the locking rod 142 out of the lock hole 1511.

[0052] When the inspection plate 122 is in the locked state, the locking rod 142 is fully inserted into the lock hole 1511, and both the first elastic element 143 and the second elastic element 153 are under stress. At this time, the inspection plate 122 is firmly connected to the plate body 121, covering the inspection hole 1212 and preventing external dust, moisture, etc. from entering the wiring channel 1211, ensuring the normal operation of the battery module 130. When it is necessary to open the inspection hole 1212 for maintenance, the technician can press the end of the unlocking rod 152 that extends out of the lock hole 1511, causing the unlocking rod 152 to move and push the locking rod 142 out of the lock hole 1511. Subsequently, the technician can rotate the inspection plate 122, causing the inspection plate 122 to rotate around the pivot 123 to a suitable position, thereby exposing the inspection hole 1212, which facilitates the technician to perform circuit testing or wire 131 connection operations.

[0053] In this embodiment, the first locking structure 140 is disposed on the side wall of the inspection plate 122 facing the wiring channel 1211, and the second locking structure 150 is disposed on the side wall of the plate body 121 facing the wiring channel 1211. It is understood that in other embodiments, the first locking structure 140 can also be disposed on the side wall of the plate body 121 facing the wiring channel 1211, and the second locking structure 150 can be disposed on the side wall of the inspection plate 122 facing the wiring channel 1211, which can also achieve locking and fixing between the inspection plate 122 and the plate body 121.

[0054] In some embodiments, a third elastic element 124 is provided between the access panel 122 and the panel body 121. The third elastic element 124 provides a spring force to the access panel 122 in the direction away from the wiring channel 1211. Optionally, the third elastic element 124 is a torsion spring, with one end fixed to the access panel 122 and the other end fixed to the panel body 121. Under the action of the third elastic element 124, when the unlocking lever 152 is pushed to disengage the locking lever 142 from the lock hole 1511, the access panel 122 will automatically spring open to open the access hole 1212, further improving the user experience.

[0055] Secondly, this application also provides a household storage integrated machine, referring to Figure 9 The integrated home energy storage unit includes an inverter 200 and at least one energy storage battery 100 provided in the first aspect embodiment, wherein the inverter 200 is electrically connected to the energy storage battery 100.

[0056] Inverter 200 is a power electronic device that converts DC to AC power. Inverter 200 can be stacked on top of multiple energy storage batteries 100, specifically using a bidirectional converter topology. The bidirectional conversion of electrical energy is achieved by controlling the on / off states of power devices such as IGBTs or MOSFETs. Electrical connection refers to the circuit conduction relationship between battery packs and between energy storage batteries 100 and inverter 200. This can be achieved using copper busbars, cables, or connectors to create a low-impedance path and ensure efficient power transmission. When power needs to be supplied to an external load or the grid, the DC power output from the energy storage device is converted to AC power by inverter 200 and output through the grid interface. When charging the energy storage device, the AC power input from the grid is converted to DC power by inverter 200, and the battery pack is charged and controlled by the battery management system. This allows for the storage of electrical energy when there is a surplus of grid power and the release of electrical energy when there is a shortage of grid power, achieving energy balance between the grid and the energy storage device.

[0057] In addition, the integrated home energy storage unit may also include a base 300, on which multiple energy storage batteries 100 are stacked to support the stacked batteries and improve the stability of the integrated home energy storage unit during use.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
