[0049] An energy storage device is an integrated battery unit and control cabinet. The control cabinet and battery unit are coupled together to manage the battery unit and utilize the conversion between electrical energy and chemical energy to store and output electrical energy. The battery unit can serve as a backup power source, perform peak shaving and valley filling when the power system supply is uneven, regulate frequency when the power system load or power generation is high, or be applied in photovoltaic-storage power generation systems.

[0050] In energy storage devices, control devices, combiner devices, and other components are typically housed within the electrical compartment, each with its own independent enclosure. However, during installation, a certain amount of space needs to be left between the enclosures, resulting in low overall space utilization of the electrical compartment and requiring a large number of wiring harnesses to pass through and into different enclosures, leading to complex wiring harness arrangements.

[0051] Based on the above considerations, in order to alleviate the current problem of low space utilization in electrical compartments, this application provides an energy storage device. An electrical box is set up in the electrical compartment, and the busbar assembly, power distribution assembly, control assembly, and power supply assembly are all set up in the electrical box. Under this arrangement, the busbar assembly, power distribution assembly, control assembly, and power supply assembly are set up in the same box, which reduces the number of boxes in the electrical compartment and thereby reduces the space occupied by the boxes of different electrical components in the electrical compartment, and also facilitates the simplification of wiring harness layout.

[0052] When the busbar, distribution, control and power components are housed in the same enclosure, the interior of the enclosure is quite compact, making it difficult to leave room for other electronic devices, especially for devices that need to be installed on a horizontal surface, where there is a lack of mounting space inside the enclosure.

[0053] In view of this, in the energy storage device provided in this application, when the busbar assembly, power distribution assembly, control assembly, and power supply assembly are housed in the same enclosure, a bracket is added to provide support for the electronic components, so that the electronic components can overlap with the control assembly and / or power distribution assembly in a first direction, thereby improving the utilization rate of the internal space of the enclosure; the bracket is arranged at intervals with the control assembly and / or power distribution assembly to reduce the risk of interference between the bracket and the electronic components on it and the control assembly and / or power distribution assembly; when the busbar assembly, power distribution assembly, control assembly, and power supply assembly occupy most of the space inside the enclosure, the bracket provides additional mounting positions for the electronic components, thereby improving the utilization rate of the internal space of the enclosure.

[0054] The energy storage device disclosed in this application can be used in the industrial field, such as for balancing loads and reducing peak-valley differences; it can also be used in commercial complexes to achieve peak shaving and valley filling and intelligent management of electricity, etc.

[0160] The support plate portion 22 is connected to the connecting body 211. When the support plate portion 22 includes the support body 221 and the first support portion 222, the support body 221 is connected to the connecting body 211, and the first support portion 222 can also be connected to the connecting body 211.

[0163] The length direction of the third support portion 213 is parallel to the first direction, or the length direction of the third support portion 213 is set at an acute angle to the first direction, that is, the length direction of the third support portion 213 is not perpendicular to the first direction; since the bearing plate portion 22 is located on the side of the connecting plate portion 21 away from the third wall 13, when the bearing plate portion 22 is subjected to the pressure of the electronic device 30, the force transmitted from the bearing plate portion 22 to the connecting plate portion 21 will cause the connecting plate portion 21 to deform toward the third wall 13, or cause the connecting plate portion 21 to have a tendency to deform toward the third wall 13; accordingly, the third support portion 213 is provided, and the length direction of the third support portion 213 is parallel to the first direction or set at an acute angle to the first direction, so as to suppress the deformation of the connecting plate portion 21 toward the third wall 13 by the second support portion 23.

[0164] For example, the length direction of the third support 213 is parallel to the first direction.

[0165] In this embodiment, a third support portion 213 is provided on the side of the connecting body 211 away from the bearing plate portion 22, so as to suppress the deformation of the connecting body 211 away from the bearing plate portion 22 by the third support portion 213, thereby improving the strength of the connecting body 211 and the support performance of the connecting body 211 on the bearing plate portion 22.

[0166] refer to Figures 5 to 8In some embodiments, the third support 213 and the connecting body 211 are an integral structural component.

[0167] The third support part 213 and the connecting body 211 are an integral structural component. In this case, the third support part 213 can be formed by bending the connecting body 211, or the third support part 213 can be integrally formed with the connecting body 211 in other ways.

[0168] For example, the third support portion 213 is formed by bending the connecting body 211 in a direction away from the bearing plate portion 22.

[0169] The third support part 213 and the connecting body 211 are integrated into a single structural component to improve the strength of the connection between the third support part 213 and the connecting body 211, thereby improving the support performance of the connecting body 211 and the overall strength of the connecting plate part 21; it also simplifies the processing steps of the bracket 20 and facilitates improved processing efficiency.

[0170] In this embodiment, the third support part 213 and the connecting body 211 are integrated into a single structural component. This improves the connection stability between the third support part 213 and the connecting body 211, and also enhances the support performance of the third support part 213 on the connecting body 211. Furthermore, it simplifies the processing steps and improves processing efficiency.

[0171] refer to Figures 5 to 8 In some embodiments, the third support portion 213 is located on the side of the connecting body 211 away from the bearing plate portion 22.

[0173] Since the connecting body 211 tends to deform toward the third wall 13 when it is under the load of the bearing plate 22, the third support 213 is set on the side of the connecting body 211 away from the bearing plate 22 in order to better suppress the deformation of the connecting body 211, improve the strength of the connecting body 211, and also improve the overall strength of the connecting plate 21.

[0174] In the technical solution of this embodiment, the third support part 213 is disposed on the side of the connecting body 211 away from the bearing plate part 22, so as to better suppress the deformation of the connecting body 211 through the third support part 213 and facilitate the improvement of the overall strength of the connecting plate part 21.
