Description

Technical Field

[0001] The present invention relates to the technical field of energy storage batteries, and particularly to a container-type battery energy storage device. Background Art

[0002] At present, energy storage battery systems have been increasingly widely used in various links from power generation to power consumption in the fields of new energy, smart grid, energy-saving technology, etc. Among them, the internal space of the energy storage container is limited, resulting in the separation, binding and fixing of the internal power lines, acquisition communication lines and secondary power line bundles being closely related to the power safety and mechanical stability of the battery system. Therefore, reasonably separating and binding the wire bundles plays a crucial role in the operation stability and transportation of the energy storage system.

[0003] In the prior art, generally, the bottom beam of the container is opened with holes, and the wire bundles pass through the holes in multiple bottom beams to achieve the separation of high-voltage and low-voltage wire bundles.

[0004] However, this method in the prior art cannot achieve the binding and fixing of the wire bundles. For mobile energy storage systems, the wire bundles are prone to scattering, posing a huge safety hazard. Moreover, opening holes in the bottom beam will affect the overall strength of the container, so it is necessary to increase the size of the bottom beam to make up for it, resulting in an increase in cost. Summary of the Invention

[0005] The present invention provides a container-type battery energy storage device to at least solve the technical problem that the energy storage device cannot simultaneously achieve the separation and binding and fixing of wire bundles, resulting in poor safety and stability.

[0006] To achieve the above object, the present invention provides a container-type battery energy storage device, including: a battery cabinet, a wire separation and binding rack, and a container. The battery cabinet has a cavity for accommodating battery modules.

[0007] The wire separation and binding rack is located at the bottom of the battery cabinet and is detachably connected to the bottom plate inside the container. The wire separation and binding rack includes at least three wire separation surfaces. A safety distance is preset between at least three wire separation surfaces. A plurality of wire separation holes are opened on each wire separation surface, and the wire separation holes are used for wire bundles to pass through and bind and fix the wire bundles.

[0008] By setting the wire separation and binding rack, the problems of wire bundle separation and binding and fixing in the battery energy storage system can be solved. For mobile systems and fixed transportation conditions, the safety and stability of the system can be ensured. Moreover, a safety distance is preset between the three wire separation surfaces, and the separation of high-voltage and low-voltage wire bundles can be achieved in a limited space, reducing the mutual interference between high-voltage and low-voltage wire bundles. In this way, it is possible to avoid opening holes in the bottom plate and bottom beam of the container to separate high-voltage and low-voltage wire bundles, resulting in an increase in the size of the bottom beam to make up for the insufficient strength and an increase in manufacturing cost.

[0009] In a possible implementation, the wire dividing and tying frame includes a horizontally arranged first wire dividing surface, and second and third wire dividing surfaces vertically fixed at both ends of the first wire dividing surface.

[0012] Optionally, the wire dividing holes on the first wire dividing surface are arranged at equal intervals, and the fixing member fixedly connects the first sub-frame and the second sub-frame through the wire dividing holes.

[0013] Optionally, one end of the first sub-frame away from the first wire dividing surface is vertically connected to a first mounting surface, and one end of the second sub-frame away from the first wire dividing surface is vertically connected to a second mounting surface.

[0014] Mounting holes are provided on the first mounting surface and the second mounting surface for fixedly connecting the first sub-frame and the second sub-frame to the bottom plate inside the container through fasteners.

[0015] Optionally, the container-type battery energy storage device further includes: a battery cabinet bracket.

[0016] The battery cabinet bracket is located at the bottom of the battery cabinet and is detachably connected to the bottom plate inside the container for supporting the battery cabinet.

[0017] Optionally, the battery cabinet bracket includes: two bracket cross beams and two bracket longitudinal beams.

[0018] The two bracket cross beams and the two bracket longitudinal beams enclose a rectangular frame body, and the wire dividing and tying frame is fixed in the center of the rectangular frame body.

[0019] Optionally, both the bracket cross beam and the bracket longitudinal beam are U-shaped beams. The battery cabinet bracket further includes support columns arranged in the U-shaped grooves of the U-shaped beams for supporting the bracket cross beams and the bracket longitudinal beams.

[0020] Optionally, the battery cabinet bracket further includes grounding columns arranged in the U-shaped grooves.

[0021] The containerized battery energy storage device provided by the present invention is provided with a wire splitting and tying rack, which is located at the bottom of the battery cabinet and is detachably connected to the bottom plate inside the container. The wire splitting and tying rack includes at least three wire splitting surfaces, and a plurality of wire splitting holes are formed on each wire splitting surface. The wire splitting holes are used for wire harnesses to pass through and tie and fix the wire harnesses. The three wire splitting surfaces are respectively used for tying and fixing power wire harnesses, acquisition and communication wire harnesses, and power supply wire harnesses, which can solve the problems of wire harness separation and tying and fixing in the battery energy storage system. For mobile systems and fixed transportation conditions, the safety and stability of the system can be ensured, and a safety distance is preset between the three wire splitting surfaces, so that the separation of high-voltage wire harnesses and low-voltage wire harnesses can be realized in a limited space, and the mutual interference between high-voltage and low-voltage wire harnesses can be reduced. In this way, it is possible to avoid increasing the size of the bottom beam to make up for the insufficient strength due to opening holes in the bottom plate and bottom beam of the container for separating high-voltage and low-voltage wire harnesses, resulting in an increase in manufacturing cost.

[0044] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0045] Currently, if a container - type battery energy storage system wants to achieve the limit and separation of high - and low - voltage wiring harnesses, it is necessary to open holes in the bottom plate and bottom beam of the container, and pass the high - and low - voltage wiring harnesses through the holes in the bottom plate of the container and lead them out and arrange them in the holes of the bottom beam. However, the high - and low - voltage wiring harnesses in the holes of the bottom beam are prone to scatter in the mobile application scenarios of the energy storage system, resulting in a reduction in the stability and safety of the entire system. Moreover, if holes are opened in the bottom plate and bottom beam, the overall strength of the container will be affected, and only by increasing the size of the bottom beam can the overall strength of the container be compensated. In this way, the manufacturing cost of the container - type battery energy storage system will be increased.

[0046] In view of this, the containerized battery energy storage device provided by the embodiments of the present invention, by providing a wire splitting and tying rack, which is located at the bottom of the battery cabinet and detachably connected to the bottom plate inside the container, the wire splitting and tying rack includes at least three wire splitting surfaces, and a plurality of wire splitting holes are formed on each wire splitting surface. The wire splitting holes are used for the wire harness to pass through and tie and fix the wire harness. The three wire splitting surfaces are respectively used for tying and fixing the power wire harness, the acquisition and communication wire harness, and the power supply wire harness, which can solve the problems of wire harness separation and tying and fixing in the battery energy storage system. For mobile systems and fixed transportation conditions, the safety and stability of the system can be ensured, and a safety distance is preset between the three wire splitting surfaces, and the separation of high-voltage wire harnesses and low-voltage wire harnesses can be realized in a limited space, reducing the mutual interference between high- and low-voltage wire harnesses. In this way, it is possible to avoid increasing the size of the bottom beam to make up for the insufficient strength due to opening holes in the bottom beam of the container for separating high- and low-voltage wire harnesses, resulting in an increase in manufacturing cost.

[0047] The present invention will be described below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0048] Embodiment

[0049] Figure 1 FIG. is a schematic structural diagram of a containerized battery energy storage device provided by an embodiment of the present invention. Figure 2 FIG. is a schematic structural diagram of a wire splitting and tying rack provided by an embodiment of the present invention.

[0050] Refer to Figures 1 to 2 As shown, an embodiment of the present invention provides a containerized battery energy storage device, including: a battery cabinet 100, a wire splitting and tying rack 200, and a container 300.

[0051] The battery cabinet 100 has a cavity for accommodating battery modules. The wire splitting and tying rack 200 is located at the bottom of the battery cabinet 100 and is detachably connected to the bottom plate inside the container 300. The wire splitting and tying rack 200 includes at least three wire splitting surfaces, and a safety distance is preset between at least three wire splitting surfaces. A plurality of wire splitting holes 201 are formed on each wire splitting surface, and the wire splitting holes 201 are used for the wire harness to pass through and tie and fix the wire harness.

[0052] Specifically, the battery module is formed by connecting single cells or battery modules in series and parallel and is installed in the cavity of the battery cabinet 100.

[0053] Among them, the wire splitting and tying rack 200 includes at least three wire splitting surfaces, and wire splitting holes 201 are formed on each wire splitting surface. At least three wire splitting surfaces are respectively used for tying and fixing the power wire harness, the acquisition and communication wire harness, and the power supply wire harness. Among them, the power wire harness and the acquisition and communication wire harness are high-voltage wire harnesses, and the power supply wire harness is a low-voltage wire harness. In this way, the separation and tying and fixing of high- and low-voltage wire harnesses can be realized. In mobile and fixed transportation conditions, the wire harness will not be scattered, and the stability and safety of the entire battery energy storage system can be improved.

[0054] Moreover, a safety distance is preset between at least three wire-splitting planes. The at least three wire-splitting planes are respectively used for binding and fixing the power harness, the acquisition and communication harness, and the power supply harness. The preset safety distance can reduce the mutual interference between the harnesses.

[0055] The wire-splitting and binding rack 200 is located at the bottom of the battery cabinet 100 and is detachably connected to the bottom plate inside the container 300, which can facilitate the guiding and hiding of the harnesses. It should be noted that the wire-splitting and binding rack 200 can also be installed at any position of the container 300, and specific settings need to be made according to the specific situation. There is no restriction on the installation position of the wire-splitting and binding rack 200 here.

[0056] It is easy to understand that by setting the wire-splitting and binding rack 200, the separation and binding and fixing of the high-voltage and low-voltage harnesses can be realized, and it can be avoided that opening holes in the bottom plate and bottom beam of the container 300 leads to an increase in the size of the bottom beam and an increase in the manufacturing cost.

[0057] Of course, the present invention is not limited thereto. In a possible implementation manner, referring to Figure 2 As shown, the wire-splitting and binding rack 200 includes a horizontally arranged first wire-splitting plane 10 and second wire-splitting planes 20 and third wire-splitting planes 30 vertically fixed at both ends of the first wire-splitting plane 10. At this time, the wire-splitting and binding rack 200 is in a "U" shape. It is easy to understand that the "U" shape structure can increase the structural stability of the wire-splitting and binding rack 200.

[0058] Among them, the wire-splitting holes 201 on the first wire-splitting plane 10 can be used to bind and fix the power harness, and the wire-splitting holes 201 on the second wire-splitting plane 20 and the third wire-splitting plane 30 can be used to bind and fix the acquisition and communication harness and the power supply harness respectively.

[0059] Furthermore, continuing to refer to Figure 2 As shown, the wire-splitting and binding rack 200 may include a first sub-rack 210 and a second sub-rack 220. Among them, the first sub-rack 210 includes the second wire-splitting plane 20 and at least part of the first wire-splitting plane 10, and the second sub-rack 220 includes the third wire-splitting plane 30 and at least part of the first wire-splitting plane 10.

[0060] It can be understood that dividing the wire-splitting and binding rack 200 into the first sub-rack 210 and the second sub-rack 220 can be used to adjust the separation distance between the harnesses to meet the design specifications. Specifically, if it is necessary to increase the distance between the harnesses, the distance between the first sub-rack 210 and the second sub-rack 220 can be increased. If it is necessary to reduce the distance between the harnesses, the first wire-splitting plane 10 of the first sub-rack 210 and the first wire-splitting plane 10 of the second sub-rack 220 can be overlapped. The increased and decreased distances are determined according to the on-site situation.

[0061] One end of the first sub-frame 210 away from the first wire dividing surface 10 is vertically connected with a first mounting surface 211, and one end of the second sub-frame 220 away from the first wire dividing surface 10 is vertically connected with a second mounting surface 221. Mounting holes are provided on the first mounting surface 211 and the second mounting surface 221. Through the mounting holes, fasteners can be used to fixedly mount the first sub-frame 210 and the second sub-frame 220 on the bottom plate inside the container 300.

[0062] In a possible implementation, the wire dividing and binding frame 200 may further include a fixing member 202, and the fixing member 202 is used to fixedly connect a part of the first wire dividing surface 10 of the first sub-frame 210 and a part of the first wire dividing surface 10 of the second sub-frame 220.

[0063] Specifically, the fixing member 202 may be Figure 2 the fixing bolt shown in the figure. The fixing bolt passes through the wire dividing holes 201 on the first wire dividing surface 10 of the first sub-frame 210 and the wire dividing holes 201 on the first wire dividing surface 10 of the second sub-frame 220 at the same time to fix the first sub-frame 210 and the second sub-frame 220. The fixing member 202 may also be a clamping device, and the clamping device clamps the overlapping part of the first wire dividing surface 10 of the first sub-frame 210 and the first wire dividing surface 10 of the second sub-frame 220 to fix the first sub-frame 210 and the second sub-frame 220. Of course, the fixing member 202 may also be other parts or devices, which are not limited here.

[0064] Furthermore, the wire dividing holes 201 on the first wire dividing surface 10 can be arranged at equal intervals. In this way, the distance between the first sub-frame 210 and the second sub-frame 220 can be precisely adjusted by using the fixing bolt, so that the separation distance of the wire harness can be precisely controlled to meet the design specifications.

[0065] Obviously, the first sub-frame 210 and the second sub-frame 220 may also be "one-piece" or "formed integrally". It should be noted that here, two parts being "one-piece" means that the two parts cannot be disassembled, and two parts being "formed integrally" means that the two parts are processed and formed at the same time and are an integral part that cannot be disassembled.

[0066] It should be mentioned that the "U-shaped" wire dividing and binding frame 200 can also effectively constrain the distance between the high-voltage and low-voltage wire harnesses. Specifically, the power wire harness and the acquisition and communication wire harness, which are both high-voltage wire harnesses, can be relatively close to each other, and the power supply wire harness of the low-voltage wire harness can be relatively far away. For example, if the acquisition and communication wire harness is tied and fixed on the second wire dividing surface 20 of the first sub-frame 210, then the power wire harness can be tied and fixed at one end of the first wire dividing surface 10 close to the second wire dividing surface 20, and the power supply wire harness can be tied and fixed on the third wire dividing surface 30 of the second sub-frame 220. In this way, the distance between the high-voltage and low-voltage wire harnesses can be effectively constrained, and the mutual interference between the high-voltage and low-voltage wire harnesses can be reduced.

[0067] For the structure of the wire splitting and bundling rack, in another possible implementation, it can also be in a "T" shape, including a first wire splitting surface arranged vertically, and a second wire splitting surface and a third wire splitting surface perpendicularly connected to one end of the first wire splitting surface. Wire splitting holes are provided on the first wire splitting surface, the second wire splitting surface, and the third wire splitting surface. The second wire splitting surface and the third wire splitting surface can be respectively used to bind and fix the power harness and the acquisition and communication harness, while the first wire splitting surface is used to bind and fix the power supply harness.

[0068] One end of the first wire splitting surface away from the second wire splitting surface and the third wire splitting surface is fixedly or detachably connected to the bottom plate inside the container, or an installation surface can be provided at one end of the first wire splitting surface away from the second wire splitting surface and the third wire splitting surface, and installation holes are provided on the installation surface to fixedly install the wire splitting and bundling rack.

[0069] In this way, the separation, binding, and fixation of high-voltage and low-voltage harnesses can be achieved. In mobile and fixed transportation conditions, the harnesses will not be scattered, which can improve the stability and safety of the entire battery energy storage system. Similarly, by setting the "T"-shaped wire splitting and bundling rack, the separation, binding, and fixation of high-voltage and low-voltage harnesses can be achieved, and it can be avoided that opening holes on the bottom plate and bottom beam of the container 300 leads to an increase in the size of the bottom beam and an increase in manufacturing costs.

[0070] Here, it should be noted that the "J" shape and the "T" shape are understood in a broad sense, that is, the "J" shape and the "T" shape are not limited to the "J" shape or "T" shape in one plane, but can also be a three-dimensional "J" shape or a three-dimensional "T" shape.

[0071] In other possible implementations, the wire splitting and bundling rack can also be of other structures, with at least three wire splitting surfaces respectively used to bind and fix the power harness, the acquisition and communication harness, and the power supply harness, which can solve the problems of wire harness separation, binding, and fixation in the battery energy storage system. For mobile systems and fixed transportation conditions, the safety and stability of the system can be ensured, and a safety distance is preset between the three wire splitting surfaces, enabling the separation of high-voltage and low-voltage harnesses in a limited space, reducing the mutual interference between high-voltage and low-voltage harnesses, and moreover, it can be avoided that opening holes on the bottom plate and bottom beam of the container to separate high-voltage and low-voltage harnesses leads to an increase in the size of the bottom beam and an increase in manufacturing costs as a limitation. For other structural forms of the wire splitting and bundling rack, no restrictions are made here.

[0072] The wire splitting and bundling rack provided by the embodiment of the present invention is simple, convenient, efficient, and reliable. Without affecting the overall strength and manufacturing cost of the container, it can achieve the binding and fixation of the power harness, the acquisition and communication harness, and the power supply harness, as well as the separation of high-voltage and low-voltage harnesses.

[0073] Figure 3 For the structural schematic diagram of the battery cabinet bracket and the position schematic diagram of the wire splitting and bundling rack provided by the embodiment of the present invention, refer toFigure 3 As shown in the figure, the containerized battery energy storage device may further include: a battery cabinet support 400, which is located at the bottom of the battery cabinet 100 and is detachably connected to the bottom plate inside the container 300 for supporting the battery cabinet 100.

[0074] It is easy to understand that on the one hand, the battery cabinet support 400 can be used to support the battery cabinet 100, and on the other hand, it can also raise the bottom space of the battery cabinet 100, facilitating wiring and the installation of the wire dividing and binding rack 200.

[0075] In order to save materials and simplify the design, the battery cabinet support 400 can be a rectangular frame formed by closing two support cross beams 410 and two support longitudinal beams 420. The wire dividing and binding rack 200 can be fixed at the central position of the rectangular frame, facilitating the wiring of the battery cabinet and binding and fixing the wire harness.

[0076] In order to further save materials and reduce the weight of the containerized battery energy storage device, both the support cross beam 410 and the support longitudinal beam 420 are U-shaped beams. The U-shaped beams lie on their sides and are fixedly connected by means of slot-to-slot clamping. In order to ensure the stability of the fixed connection, they can also be fixed at the junction of the support cross beam 410 and the support longitudinal beam 420 by welding or fasteners.

[0077] In order to ensure the stability of the battery cabinet support 400, the battery cabinet support 400 further includes a support column 430. The support column 430 is arranged inside the U-shaped beam and supports at the opening of the U-shaped groove, playing a role in maintaining the stability of the support cross beam 410 and the support longitudinal beam 420.

[0078] It is easy to think that the support column can also be a U-shaped column, which can further reduce the weight of the containerized energy storage device and save costs, and there is no restriction here.

[0079] Furthermore, the battery cabinet support 400 may further include a grounding column 440. The grounding column 440 is fixedly connected inside the U-shaped beams of the support cross beam 410 and the support longitudinal beam 420, facilitating the grounding of the cable and ensuring the safety performance of the entire system.

[0080] The containerized battery energy storage device provided by the present invention solves the problems of harness separation and binding fixation in the battery energy storage system by providing a wire splitting and binding rack. The wire splitting and binding rack is located at the bottom of the battery cabinet and is detachably connected to the bottom plate inside the container. The wire splitting and binding rack includes at least three wire splitting surfaces, and a plurality of wire splitting holes are formed in each wire splitting surface. The wire splitting holes are used for the wire harness to pass through and bind and fix the wire harness. At least three wire splitting surfaces are respectively used for binding and fixing the power wire harness, the acquisition and communication wire harness, and the power supply wire harness. For mobile systems and fixed transportation conditions, the safety and stability of the system can be ensured. Moreover, a safety distance is preset between the three wire splitting surfaces, and the separation of high-voltage and low-voltage wire harnesses can be realized in a limited space, reducing the mutual interference between high-voltage and low-voltage wire harnesses. In this way, it is possible to avoid increasing the size of the bottom beam to make up for the insufficient strength caused by opening holes in the bottom plate and bottom beam of the container for separating high-voltage and low-voltage wire harnesses, resulting in an increase in manufacturing costs.
