[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] An energy storage device is a device that converts external energy into electrical energy and stores it inside to supply power to external electrical devices when needed. In HVAC equipment, energy storage devices can store electricity when the power network load is not too large, and release electricity when the power network load is large or in some emergency situations, thereby ensuring the continuous operation of HVAC equipment.

[0050] In the related art, the energy storage device includes an electrical cabinet, an inverter assembly and a battery assembly, wherein the inverter assembly and the battery assembly are both housed in the electrical cabinet and are respectively arranged at different positions in the electrical cabinet, resulting in a relatively complex overall structure of the energy storage device and complex wiring between the inverter assembly and the battery assembly.

[0051] To solve the above problems, please refer to Figure 1 The present application proposes a HVAC device. In this embodiment, the HVAC device includes an electrical device (not shown in the figure) and an energy storage device 100. The electrical device may be a HVAC device, and the HVAC device includes but is not limited to air conditioners, multi-split units, heat pumps, water heaters and other devices. In actual use, the energy storage device 100 can transfer the electric energy stored in it into the electrical device when the electrical device needs to be powered, thereby meeting the user's usage needs.

[0052] In order to protect the stability of the energy storage device 100 in transmitting electric energy and improve the overall appearance of the energy storage device 100, specifically, please refer to Figures 1 to 3 The energy storage device 100 proposed in the embodiment of the present application may include a battery assembly 10 and an inverter assembly 30 .

[0053] The battery assembly 10 is used to store electric energy inside and is electrically connected to the inverter assembly 30 to transmit the electric energy inside to the inverter assembly 30 in the power supply scenario. The battery assembly 10 may include a battery module 11 and a control module 13. The battery module 11 is arranged in a square shape and is used to store or release electric energy. The control module 13 may also be arranged in a square shape and may be electrically connected to the battery module 11 by hot plugging or other connection methods to manage and control the operation of the battery module 11.

[0054] The control module 13 may include a first housing 131 and components such as a battery management component (not shown in the figure), an energy management component (not shown in the figure), a charging controller (not shown in the figure), and a third interface 111. The first housing 131 defines the outline of the entire control module 13, and the first housing 131 may be made of metal materials such as aluminum and steel to have greater strength, and the metal material has excellent thermal conductivity, so that the first housing 131 has a good heat dissipation effect and can promptly dissipate the heat generated by the components. Of course, the first housing 131 may also be made of other materials such as plastic, and the embodiment of the present application does not limit this. The battery management component, the energy management component, and the charging controller are accommodated in the first housing 131, and the third interface 111 is set on the first housing 131 of the battery assembly 10. It can be understood that the battery management component, the energy management component, and the charging controller enable the control module 13 to specifically monitor the voltage, current, temperature and other parameters of the battery module 11, and control the charging and discharging process of the battery module 11.

[0055] In some structural forms, the battery module 11 may include multiple battery submodules, which may be split structures and stacked one on another, and two adjacent battery submodules may be electrically connected by hot plugging, and the battery submodule closest to the control module 13 may be electrically connected to the control module 13 by hot plugging, so that the battery module 11 as a whole can be electrically connected to the control module 13. In this way, in the actual assembly process, the manufacturer can select the corresponding number of battery submodules for assembly according to the power supply requirements customized by the user, so as to achieve a higher degree of customization and meet the needs of different users.

[0056] The inverter assembly 30 is used to convert the electric energy transmitted by the battery module 11 of the battery assembly 10 from direct current to alternating current. Specifically, the inverter assembly 30 may include an inverter body 31 and a wiring module 33. The inverter body 31 may include a second housing 313 and components such as a transformer (not shown in the figure), a power electronic switch (such as a transistor, a field effect tube, etc.) (not shown in the figure). The second housing 313 may be arranged in a square shape, and the second housing 313 may be made of metal materials such as aluminum and steel to have greater strength, and the metal material has excellent thermal conductivity, so that the heat dissipation effect of the second housing 313 is better, and the heat generated by the components can be promptly dissipated to the outside. Of course, the second housing 313 may also be made of other materials such as plastic, and the embodiment of the present application is not limited to this. Components such as transformers, reactors, power electronic switches (such as transistors, field effect tubes, etc.) are accommodated in the second housing 313, and can cooperate to convert electric energy from direct current to the required alternating current.

[0057] The wiring module 33 may include a third housing 335, a first interface 331, a second interface 333, a socket and other components. The third housing 335 may also be arranged in a square shape, and the interior is connected to the interior of the second housing 313. The third housing 335 may be an integral structure with the second housing 313, and cooperate to define the outline of the entire inverter assembly 30. The projection of the third housing 335 in the height direction of the energy storage device 100 is located in the second housing 313. Among them, the third housing 335 may be made of metal materials such as aluminum and steel to have greater strength, and the metal material has excellent thermal conductivity, so that the third housing 335 has a better heat dissipation effect and can promptly dissipate the heat generated by the components. Of course, the third housing 335 may also be made of other materials such as plastic, and the embodiment of the present application is not limited to this.

[0058] The wiring module 33 is located between the inverter body 31 and the battery assembly 10. In an exemplary manner, the wiring module 33 may be located between the inverter body 31 and the control module 13 of the battery assembly 10, specifically, the third housing 335 is fixedly connected to the first housing 131 through an angle code, or it may be fixed by a buckle or the like, and the embodiment of the present application does not limit this. In another exemplary manner, the wiring module 33 may be located between the inverter body 31 and the battery module 11 of the battery assembly 10, and the embodiment of the present application does not limit this.

[0059] The wiring module 33 is also electrically connected to the battery assembly 10. For example, the wiring module 33 can be hot-pluggably connected to the wiring module 33 of the battery assembly 10, or connected via a wire, which is not limited in the embodiment of the present application.

[0060] In some embodiments, the first interface 331 and the second interface 333 respectively arranged on the third housing 335 of the wiring module 33, and the components such as the socket housed in the third housing 335 can play the role of physically transmitting electrical energy. Among them, the two ends of the external first wire are respectively connected to the first interface 331 of the wiring module 33 and the third interface 111 of the battery assembly 10, and one end of the external second wire is connected to the second interface 333 of the wiring module 33, and the other end is used to connect the electrical device, that is, the first wire plays the role of electrically connecting the wiring module 33 and the control module 13 of the battery assembly 10, and the second wire plays the role of electrically connecting the wiring module 33 and the electrical device, so that the electrical device can be electrically connected to the wiring module 33.

[0061] In summary, by arranging the wiring module 33 between the inverter body 31 and the battery assembly 10, the energy storage device 100 of this embodiment has at least the following technical effects:

[0062] The inverter body 31, the wiring module 33 and the battery assembly 10 are arranged from top to bottom. Compared with the related art in which an electrical cabinet is provided to accommodate the inverter assembly and the battery assembly 10 respectively, the electrical cabinet can be eliminated in this embodiment, that is, the inverter body 31, the wiring module 33 and the battery assembly 10 are the overall external structure of the energy storage device 100 of this embodiment, and the structure is simpler.

[0063] Furthermore, by positioning the wiring module 33 between the inverter body 31 and the battery assembly 10, electrical connection between the wiring module 33 and the battery assembly 10 can be more convenient. The wiring path of the wire is shorter than when the wiring module 33 is positioned on the side of the inverter body 31 away from the battery assembly 10, thereby simplifying the wiring path.

[0064] Finally, when the battery assembly 10 is arranged below the inverter body 31 and the wiring module 33, it can prevent the battery assembly 10 from being too heavy and squeezing the inverter body 31 and the wiring module 33, thereby effectively preventing the inverter body 31 and the wiring module 33 from being squeezed and damaged. At the same time, based on this, the number of battery submodules in the battery module 11 of the battery assembly 10 can be adjusted according to the actual needs of different users, avoiding excessive squeezing of the inverter body 31 and the wiring module 33 by increasing the number of battery submodules due to the large power demand of some users.

[0065] Please continue to refer to Figures 1 to 3In some embodiments, the energy storage device 100 further includes a decorative plate 50. The decorative plate 50 may be roughly L-shaped or C-shaped, etc., and the decorative plate 50 may be made of metal materials such as aluminum and steel to have greater strength, and the outer panel surface has a higher glossiness and is relatively flat, so that the decorative plate 50 has better aesthetics. Of course, the decorative plate 50 may also be made of other materials such as plastic, which is not limited in the embodiment of the present application. The decorative plate 50 is located between the battery assembly 10 and the inverter body 31, and the inverter body 31, the decorative plate 50 and the battery assembly 10 as a whole jointly define the square outline of the entire energy storage device 100. In addition, the decorative plate 50 blocks at least part of the wiring module 33, thereby also blocking the first wire and part of the second wire, wherein the first wire may be blocked by the decorative plate 50 as a whole or partially by the decorative plate 50, which is not limited in the embodiment of the present application. The decorative plate 50 is also provided with a first opening 55 for the second wire to pass through.

[0066] Based on the above, the decorative plate 50 is located between the battery assembly 10 and the inverter 31, and shields at least part of the wiring module 33, and also has the following technical effects:

[0067] By providing a decorative plate 50 for shielding at least part of the wiring module 33 between the battery assembly 10 and the inverter body 31, the solution of the present application isolates the wiring module 33 in a relatively closed space through the decorative plate 50, the battery assembly 10 and the inverter body 31, so that during use, external dust is not easy to adhere to the wiring module 33, thereby preventing the wiring module 33 from having poor electrical connection stability or even short circuit due to the accumulation of foreign matter during long-term use. Of course, by shielding the wiring assembly with the decorative plate 50, the situation of maintenance personnel accidentally touching the large wiring module 33 can also be greatly reduced, so that the safety of the energy storage device 100 can be comprehensively improved.

[0068] Of course, by providing the decorative plate 50 , the outer wall surface between the battery assembly 10 and the inverter body can be more integrated, making the overall appearance of the energy storage device 100 more beautiful.

[0069] Please continue to refer to Figures 1 to 3In some embodiments, the energy storage device 100 may further include a base 90, which is installed at the bottom of the battery module 11 of the battery assembly 10, that is, the base 90 is installed at the bottom of the battery submodule closest to it, so that the base 90 can be used to support the battery assembly 10 and the inverter assembly 30, so as to improve the stability of the energy storage device 100 and reduce the risk of the inverter assembly 30 and the battery assembly 10 tipping over. Among them, the bottom of the base 90 may be provided with a pulley to facilitate the staff to move the energy storage device 100 and adjust the installation position of the energy storage device 100; the bottom of the base 90 may also be provided with a plurality of support feet 91, and the plurality of support feet 91 are arranged at intervals along the circumference of the base 90, so as to further improve the stability of the base 90 by connecting the support feet 91 to the ground of the installation environment.

[0070] Please refer to Figures 2 to 4 In some embodiments, the first interface 331 is disposed on one side of the third housing 335 of the wiring module along the left-right direction, and the second interface 333 is disposed on the other side of the third housing 335 of the wiring module along the left-right direction. Figure 6 The decorative panel 50 may include a front panel 51 and two side panels 53, wherein the side panel 53 is connected to one side of the front panel 51 along the left-right direction thereof, and the other side panel 53 is connected to the other side of the front panel 51 along the left-right direction thereof, that is, the decorative panel 50 is roughly C-shaped, and the two side panels 53 are spaced apart to form a first opening 55. Among them, one side panel 53 corresponds to the first interface 331 and is used to shield the first wire, and the other side panel 53 corresponds to the second interface 333 and is used to shield part of the second wire. In this way, the first wire and the second wire can be located at different sides to avoid the first wire and the second wire being entangled and cluttered and unsightly, and based on this, a correspondingly adapted decorative panel 50 may also be provided, and the first wire and the second wire may be protected and shielded respectively by the front panel 51 of the decorative panel 50 and the two side panels 53. Among them, the front panel 51 and the two side panels 53 can be an integrated structure with better strength, and there are no splicing marks as a whole, which is more beautiful. Of course, the front panel 51 and the two side panels 53 can also be split structures and connected by bonding, clamping or threaded connection.

[0071] In other embodiments, the first interface 331 and the second interface 333 may also be arranged on the same side of the third shell 335 of the wiring module, and the first wire and the second wire will also be wired on the same side of the third shell 335. In this way, the decorative panel 50 can correspond to the form of a front panel 51 and a side panel 53, that is, the decorative panel 50 is roughly L-shaped, and the wires are shielded and protected by the side panel 53 and the front panel 51.

[0072] Please refer to Figure 3In the actual assembly process, on the basis that the decorative plate 50 is roughly C-shaped, the decorative plate 50 can be pushed from the front to the back to between the first housing 131 of the battery assembly 10 and the second housing 313 of the inverter body 31, and then the subsequent fixed installation is performed. When the appearance of the energy storage device 100 is consistent from front to back, the decorative plate 50 can also be pushed from the back to the front to between the first housing 131 of the battery assembly 10 and the second housing 313 of the inverter body 31, and it is only necessary to ensure that the front plate 51 of the decorative plate 50 remains facing the user in the actual use scenario. On the basis that the decorative plate 50 is roughly L-shaped, it can be pushed from the side for assembly, or it can be pushed from the front to the back for assembly as mentioned above, or when the appearance of the energy storage device 100 is consistent from front to back, it can also be pushed from the back to the front for assembly, and the embodiments of the present application are not limited to this.

[0073] In some usage scenarios, the electrical device will be deployed on the side of the energy storage device 100. Based on this, in order to facilitate the outlet of the second wire, at least one side plate 53 of the embodiment of the present application is provided with a second opening 57, and the second opening 57 is used for the second wire to pass through. In this way, the second wire can be directly passed through the second opening 57, without passing through the first wiring part, and the outlet path is shorter, and it is convenient for the staff to arrange the wiring.

[0074] Of course, if the appearance of the energy storage device 100 is consistent from front to back, and the decorative panel 50 is roughly C-shaped, then when both side panels 53 are provided with a second opening 57, the decorative panel 50 can be pushed between the first shell 131 of the battery assembly 10 and the second shell 313 of the inverter body 31, either from front to back or from back to front, for subsequent fixed connection steps.

[0075] Alternatively, when the third interface 111 is arranged on the side of the battery assembly 10, the first wire needs to pass through the decorative panel 50 to be connected to the third interface 111. In this way, both side panels 53 can be provided with a second wiring portion, wherein the second wiring portion of the side panel 53 corresponding to the first interface 331 is provided for the first wire to pass through and route, and the second wiring portion of the side panel 53 corresponding to the second interface 333 is provided for the second wire to pass through and route. In this way, the outlet paths of the first wire and the second wire can be shortened, making it easier for staff to arrange the wiring.

[0076] Please refer to Figure 1 to Figure 2In some structural forms, the outer surface of the decorative plate 50 is coplanar with the outer side surface of the first housing 131 of the battery assembly 10, and is coplanar with the outer side surface of the second housing 313 of the inverter body 31. This arrangement can make the overall outer surface of the energy storage device 100 smoother and the overall appearance more uniform, thereby making the overall aesthetics of the energy storage device 100 better.

[0077] The above content introduces the advantages of the energy storage device 100 of the embodiment of the present application in that the decorative plate 50 can shield and protect the first wire and the second wire. Figures 4 to 7 In some embodiments, the side panel 53 of the decorative panel 50 is provided with a first sliding portion 531, and the second shell 313 of the inverter body 31 is provided with a second sliding portion 311. The first sliding portion 531 and the second sliding portion 311 are slidably matched, so that the decorative panel 50 can be slidably connected to the inverter body 31. In this way, when the decorative panel 50 is pushed between the first shell 131 of the battery assembly 10 and the second shell 313 of the inverter body 31, the first sliding portion 531 and the second sliding portion 311 can cooperate to achieve a guiding effect, improve the movement accuracy, and avoid the decorative panel 50 from contacting and deforming with the first shell 131 of the battery assembly 10 and the second shell 313 of the inverter body 31 during the pushing process.

[0078] Further, the first sliding portion 531 is a first flange 5311 disposed on the edge of the side plate 53 of the decorative plate 50, and the second sliding portion 311 is a second flange 3111 disposed on the edge of the second housing 313 of the inverter body 31. The first flange 5311 and the second flange 3111 are slidably connected to enable the decorative plate 50 and the inverter body 31 to slide and cooperate. In this way, when the decorative plate 50 and the second housing 313 are in the manufacturing process, the first flange 5311 and the second flange 3111 can be formed by stamping or the like. In this way, compared with the first sliding portion 531 being one of a slider and a slide rail, the second sliding portion 311 is the other of a slider and a slide rail. In the embodiment of the present application, there is no need to additionally provide a structure of a slider and a slide rail, thereby reducing the number of components, making the energy storage device 100 simpler in structure and having lower production costs. Of course, the structural form of the first sliding portion 531 and the second sliding portion 311 can also be a slider and a slide rail, which is not limited in the embodiment of the present application.

[0079] Of course, in other structural forms, the first shell 131 of the battery assembly 10 may be provided with a second sliding portion 311, that is, the edge of the first shell 131 of the battery assembly 10 is provided with a second flange 3111, so that the decorative panel 50 and the battery assembly 10 can slide together; or the first shell 131 of the battery assembly 10 and the second shell 313 of the inverter body 31 may be provided with a second sliding portion 311, that is, the edge of the first shell 131 of the battery assembly 10 and the edge of the second shell 313 of the inverter body 31 are provided with a second flange 3111, so that the decorative panel 50 and the battery assembly 10 and the inverter body 31 can slide together, which can further improve the accuracy of the movement of the decorative panel 50, and the embodiment of the present application is not limited to this.

[0080] In order to further improve the external aesthetics of the energy storage device 100, the first flange 5311 is connected to the inner side of the side plate 53 of the decorative plate 50, and in the assembled state, the second flange 3111 is blocked by the decorative plate 50 (such as Figure 1 ). In this way, on the basis of achieving the sliding fit between the first flange 5311 and the second flange 3111, the first flange 5311 and the second flange 3111 can be prevented from being exposed in the assembled state, thereby improving the aesthetics of the energy storage device 100. Of course, in other forms, the first flange 5311 can be connected to the outer side of the side plate 53 of the decorative plate 50, and the second flange 3111 is not blocked by the decorative plate 50 in the assembled state, and the embodiment of the present application is not limited to this.

[0081] Please refer to Figure 6 to Figure 7 In some structural forms, a reinforcing flange 59 is formed on the side of the first flange 5311 away from the decorative plate 50. It is understandable that the reinforcing flange 59 may be L-shaped, and the reinforcing flange 59 may also be formed by stamping the decorative plate 50. In this way, the strength of the first flange 5311 can be effectively improved by setting the reinforcing flange 59, so as to avoid the first flange 5311 being deformed due to poor strength, so that the first flange 5311 and the second flange 3111 cannot slide closely together, thereby ensuring the accuracy of the first flange 5311 and the second flange 3111 when sliding.

[0082] Please refer to Figure 1 , Figure 6 as well as Figure 7In some structural forms, the first flange 5311 is connected to the inner side of the side plate 53 of the decorative plate 50, and in the assembled state, the second flange 3111 is blocked by the decorative plate 50, and a reinforcing flange 59 is formed on the side of the first flange 5311 away from the decorative plate 50. In this way, on the basis of achieving the sliding fit between the first flange 5311 and the second flange 3111, the first flange 5311 and the second flange 3111 can be prevented from being exposed in the assembled state, thereby improving the aesthetics of the energy storage device 100, and the strength of the first flange 5311 can be effectively improved by setting the reinforcing flange 59, so as to prevent the first flange 5311 from being deformed due to poor strength, resulting in the first flange 5311 and the second flange 3111 being unable to slide closely together, thereby ensuring the accuracy of the first flange 5311 and the second flange 3111 when sliding.

[0083] See also Figure 6 In some structural forms, the energy storage device 100 may further include a limiting structure 70, and the limiting structure 70 includes a stopper 71 (such as Figure 3 ) and a stop fitting portion 73, the stop portion 71 is arranged on the second shell 313 of the inverter body 31, or, the stop portion 71 is arranged on the first shell 131 of the battery assembly 10, and the stop fitting portion 73 is arranged on the decorative panel 50.

[0084] The stopper 71 is used to abut against the stopper fitting part 73 to stop the stopper fitting part 73 in the sliding direction of the decorative plate 50. Specifically, the stopper 71 and the stopper fitting part 73 can be L-shaped angle codes, wherein the stopper fitting part 73 is formed with a groove, and the stopper 71 can be embedded in the groove and stop the groove wall of the groove to achieve the stopping operation of the stopper fitting part 73 in the sliding direction of the decorative plate 50. In this way, when the decorative plate 50 is pushed between the first housing 131 of the battery assembly 10 and the second housing 313 of the inverter body 31, the decorative plate 50 can be installed in place through the limiting structure 70, so that the connection position between the decorative plate 50 and the first housing 131 and / or the second housing 313 in the subsequent fixed connection step is more accurate.

[0085] The above content introduces the advantages of the decorative plate 50 of the energy storage device 100 of the present application in the process of being pushed between the battery assembly 10 and the inverter body 31 in terms of the sliding form of the decorative plate 50. On this basis, please refer to Figures 2 to 3 The energy storage device 100 of the embodiment of the present application further includes a fixing structure, which is disposed between the decorative plate 50 and the second housing 313 of the inverter assembly 30 and / or the first housing 131 of the battery assembly 10, so as to relatively fix the decorative plate 50 and the inverter assembly 30 and / or the battery assembly 10. Specifically, the specific forms of the fixing structure may include but are not limited to the following:

[0086] In the first form, the decorative panel 50 is made of magnetic material, and can be a fixed structure including a magnetic attraction part (not shown in the figure) arranged on the first shell 131 of the battery assembly 10, and the decorative panel 50 is adsorbed and fixed by the magnetic attraction part; it can also be a fixed structure including a magnetic attraction part (not shown in the figure) arranged on the second shell 313 of the inverter body 31, and the decorative panel 50 is adsorbed and fixed by the magnetic attraction part; it can also be a fixed structure including magnetic attraction parts (not shown in the figure) respectively arranged on the first shell 131 of the battery assembly 10 and the second shell 313 of the inverter body 31, and the decorative panel 50 is adsorbed and fixed by the magnetic attraction part; in this way, the decorative panel 50 can be adsorbed and fixed by the magnetic attraction part by utilizing its own magnetic attraction characteristics, and in this way, it is possible to achieve installation without providing a fixing structure with obvious fixing marks such as a threaded structure, thereby improving the aesthetics and reducing the assembly steps. During the disassembly process, an external force can be applied to the decorative panel 50 from the outside, and the external force is greater than the adsorption force, so that the decorative panel 50 can be pulled out, which is easy to operate.

[0087] Of course, the decorative panel 50 made of magnetic material can also be replaced by a fixed structure that also includes a magnetic part (not shown in the figure) arranged on the decorative panel 50, and the fixation is achieved by magnetic attraction between the magnetic parts. In this case, the decorative panel 50 can be made of non-magnetic material, and the material selection range of the decorative panel 50 is wider, which is not limited by the embodiments of the present application.

[0088] In the second form, the fixing structure includes a bead portion 58 (such as Figure 6 ) and the locking portion 337 (such as Figure 3 ), the bead portion 58 is provided in cooperation with the locking portion 337, wherein one of the decorative panel 50 and the wiring module 33 is provided with the bead portion 58, and the other of the two is provided with the locking portion 337. It is understandable that the materials of the bead portion 58 and the locking portion 337 can be two materials that are magnetically attracted to each other, so that the bead portion 58 can be magnetically adsorbed by the locking portion 337 to fix the decorative panel 50. Of course, the locking portion 337 can also be in the form of a card slot, and the bead portion 58 is elastically deformed to be embedded in the locking portion 337 to fix the decorative panel 50. The embodiment of the present application does not limit this. In this way, the decorative panel 50 can be fixed after being pushed into place, reducing the assembly steps. In the disassembly process, the decorative panel 50 can also be pulled out by applying an external force to the decorative panel 50 from the outside, and the external force is greater than the adsorption force, or the external force can cause the bead portion 58 to be elastically deformed to be separated from the locking portion 337, so that the operation is convenient.

[0089] In the third form, the fixing structure includes an angle bracket, which may be L-shaped and connected between the decorative plate 50 and the first housing 131 of the battery assembly 10, or between the decorative plate 50 and the second housing 313 of the inverter body 31. In this way, the fixing connection by the angle bracket greatly improves the installation stability when the decorative plate 50 is installed between the first housing 131 of the battery assembly 10 and the second housing 313 of the inverter body 31.

[0090] In the fourth form, the edge of the front plate 51 of the decorative plate 50 may be provided with a connecting flange, which is threadedly connected to the first housing 131 of the battery assembly 10, or to the second housing 313 of the inverter body 31. In this way, the installation stability of the decorative plate 50 when installed between the first housing 131 of the battery assembly 10 and the second housing 313 of the inverter body 31 can be greatly improved by setting the connecting flange and adopting a threaded connection method. In addition, the connecting flange can be directly stamped by the decorative plate 50, so there is no need to set an additional connection structure, reducing the number of structures.

[0091] It should be noted that, among the at least four connection forms mentioned above, the energy storage device 100 of the present application may adopt any one connection form, or may adopt a combination of two or more connection forms, and the embodiments of the present application are not limited to this.
