Description

Technical Field

[0001] This invention belongs to the field of power distribution box technology, specifically relating to a portable energy storage system that improves battery performance by optimizing the spatial environment. Background Technology

[0002] Energy storage boxes play a crucial role on construction sites, offering advantages such as ease of operation and low purchase or rental costs, leading to their widespread application throughout the construction process. However, the frequent use of energy storage boxes on construction sites, coupled with the complex environment, presents challenges. For instance, during rainy weather leading to high humidity, or when water is present on the ground, water vapor can easily enter the storage box, affecting its operation and potentially reducing its lifespan. Therefore, improved sealing is essential.

[0003] In addition, there are many measures for transporting the energy storage boxes, such as manual handling, lifting equipment assistance, and forklifts. However, these usually require the use of external tools, which is costly and inconvenient. Finally, regarding heat dissipation, current energy storage boxes usually have heat dissipation structures, but heat dissipation alone cannot solve all problems. For example, the battery efficiency decreases in winter, and the temperature difference between the inside and outside of the energy storage box is large, both of which will reduce the service life of the energy storage box.

[0004] Therefore, current energy storage boxes suffer from limited general-purpose functions and low functional density. This solution proposes a portable energy storage system that improves battery performance by optimizing the spatial environment, thereby addressing the aforementioned technical challenges. Summary of the Invention

[0005] The purpose of this invention is to provide a portable energy storage system that improves battery performance by optimizing the spatial environment. It solves the technical problem of how to achieve the multi-functional effects of existing energy storage boxes, and achieves the technical effect of integrated sealing, heat dissipation and portability. It also achieves the integration of device functions without affecting the use and aesthetics of the energy storage box.

[0006] A portable energy storage system that improves battery performance by optimizing the spatial environment includes a base frame, a central control box mounted on top of the base frame, and multiple energy storage boxes disposed between the base frame and the central control box. Each energy storage box has a plug on its upper surface and a first socket on its lower surface. Adjacent energy storage boxes are connected via the plug and the first socket. The central control box is mounted on the top of each energy storage box, and a second socket is mounted on the bottom of the central control box. A lifting and transport assembly is mounted on the base frame.

[0007] The energy storage box includes a shell body, a detachable closed side plate connected to the outside of the shell body, a detachable closed end plate connected to the outside of the shell body, and multiple battery cells.

[0008] The upper end of the closed side plate is connected to the upper waterproof sealing gasket, and the inner side of the closed end plate is connected to the side waterproof sealing gasket; an electrical control board is provided on the inner side of the closed end plate, and the electrical control board is connected to the battery cell through a cable; multiple heat sinks are provided on the outer side of the closed end plate.

[0009] The heat sink is made of aluminum, and its outer side is cold-sprayed with an aluminum nitride composite coating / graphene composite coating.

[0010] The shell body has multiple waterproof compartments inside, and each waterproof compartment contains a battery cell. Two adjacent battery cells are connected by an aluminum busbar.

[0011] It also includes a heating film disposed at the bottom of the battery cell. The heating film is connected to the electrical control board via a temperature sensor, and temperature acquisition points are provided on the heating film.

[0012] The bottom of the base frame is equipped with casters, and the upper end of the base frame is vertically equipped with multiple positioning pins, which are inserted into pin holes at the bottom of the energy storage box.

[0013] The end face of the energy storage box is provided with a pressure relief valve, which connects the inside of the energy storage box with atmospheric pressure.

[0014] The lifting and transfer assembly is respectively attached to two roller drive assemblies on both sides of the energy storage box, a lead screw assembly for the two roller drive assemblies to move in opposite directions at the same time, and an adjustment assembly for the two roller drive assemblies to rotate and lift at the same time. The bottom end of the adjustment assembly is positioned and connected to the outer end of the base.

[0015] The roller drive assembly includes a vertically placed frame, multiple horizontally parallel rotating shafts arranged on the frame, multiple rollers fixedly arranged on the rotating shafts, a synchronous pulley coaxially positioned on the rotating shafts, and a synchronous belt meshing with the multiple synchronous pulleys. The outer end of one of the rotating shafts is connected to a motor. The rollers are made of rubber.

[0016] The lead screw assembly includes a horizontally arranged guide post and a lead screw, and a rotating plate coaxially fixed to the outer end of the lead screw. The guide post and the lead screw pass through the top ends of the two frames. One end of the guide post is fixedly connected to one of the frames, and the other end slides through the other frame. The two ends of the lead screw are respectively provided with a forward thread and a reverse thread, and the forward thread and the reverse thread are respectively connected to the two frames.

[0017] The adjustment assembly includes a positioning seat, guide posts that are vertically fixed at both ends of the positioning seat, a spring sleeved on the guide posts, and a stop block fixedly disposed at the outer end of the guide posts. The guide posts slide through the frame, and the stop block is disposed on the outside of the frame.

[0018] The positioning seat and the free end of the lifting cylinder are rotatably connected by a bearing, and the bottom end of the lifting cylinder is fixed to the base frame by a connecting rod.

[0019] More preferably, the electrical control board installed inside the casing in this solution is used for functions such as battery opening and closing, working time, and temperature regulation. This is existing technology and will not be described in detail here. Furthermore, all parts not described in detail in this solution adopt existing battery-related technologies and will not be described in detail here.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) This scheme is equipped with multiple energy storage boxes, which are arranged vertically to increase the energy storage capacity and save space. A plug is installed at the top of the energy storage box and a socket is installed at the bottom. Connecting the plug and socket can realize the connection between different energy storage boxes on the one hand, and limit the upper and lower energy storage boxes on the other hand to prevent them from shaking. Finally, the connection between the energy storage box and the central processing box is the same.

[0022] (2) The shell body, closed side plate, closed end plate, upper waterproof sealing gasket and side waterproof sealing gasket are connected to effectively realize the sealed connection of multiple battery cells, which helps to waterproof; at the same time, heat sink is set. In this solution, aluminum nitride composite coating / graphene composite coating is cold sprayed on the outside of the heat sink. Graphene and aluminum nitride have high thermal conductivity and heat dissipation capacity, and aluminum nitride also has strong electrical insulation capacity and strong adhesion. Combined with the base frame and universal wheels, the comprehensive technical effect of waterproof, heat dissipation and portability integrated design is realized.

[0023] (3) A heating film is installed at the bottom of the battery cell. On the one hand, the battery cell is preheated before use, which helps the battery cell to quickly enter the working state and protect the battery cell. On the other hand, when the external temperature is detected to be higher than the internal temperature of the storage box, the heating film works to maintain the internal and external temperature balance and avoid the generation of water vapor or water droplets inside, thus protecting the battery cell.

[0024] (4) A roller drive assembly is provided. When transporting the storage box, in order to save manpower, the frame is set on both sides of the storage box, and the rollers are attached to the outside of the storage box. Under the action of the screw assembly, the frame is tightly attached to the outside of the storage box. The motor works, and under the action of the squeezing force and friction, the storage box moves upward. At this time, human assistance may also be required. Finally, the lifting height and the rotation adjustment of the storage box are achieved by adjusting the assembly.

[0025] Once the transfer process is complete, the two frames are placed on either side of the central electrical control box to limit its overall position and ensure stability. Attached Figure Description

[0034] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0035] Example 1

[0036] See Figures 1-5 A portable energy storage system that improves battery performance by optimizing the spatial environment includes a base frame 32, a central control box 1 is disposed above the base frame 32, and multiple energy storage boxes 2 are disposed between the base frame 32 and the central control box 1; a plug 4 is disposed on the upper end face of the energy storage box 2 and a first socket is disposed on the lower end face, two adjacent energy storage boxes 2 are connected by the plug 4 and the first socket, the central control box 1 is disposed on the top of the energy storage box 2, and a second socket 41 is disposed on the bottom end of the central control box 1; a lifting and transfer assembly is disposed on the base frame 32.

[0037] The energy storage box 2 includes a shell body, a detachable closed side plate connected to the outside of the shell body, a detachable closed end plate connected to the outside of the shell body, and multiple battery cells.

[0038] The upper end of the closed side plate is connected to the upper waterproof sealing gasket, and the inner side of the closed end plate is connected to the side waterproof sealing gasket; an electrical control board is provided on the inner side of the closed end plate, and the electrical control board is connected to the battery cell through a cable; multiple heat sinks 6 are provided on the outer side of the closed end plate.

[0039] The heat sink 6 is made of aluminum, and its outer side is cold-sprayed with an aluminum nitride composite coating / graphene composite coating.

[0040] The shell body has multiple waterproof compartments inside, and each compartment contains a battery cell. Adjacent battery cells are connected by an aluminum busbar.

[0041] It also includes a heating film disposed at the bottom of the battery cell. The heating film is connected to the electrical control board via a temperature sensor, and temperature acquisition points are set on the heating film. The specific material used for the heating film is not limited; for example, a metal heating film can be used in this embodiment.

[0042] The bottom of the base frame 32 is equipped with casters 3, and the upper end of the base frame 32 is vertically equipped with multiple positioning pins 33, which are inserted into the pin holes at the bottom of the energy storage box 2.

[0043] The end face of the energy storage box 2 is equipped with a pressure relief valve 5, which connects the inside of the energy storage box 2 with atmospheric pressure.

[0044] More preferably, the electrical control board installed inside the casing in this solution is used for functions such as battery opening and closing, working time, and temperature regulation. This is existing technology and will not be described in detail here. Furthermore, all parts not described in detail in this solution adopt existing battery-related technologies and will not be described in detail here.

[0045] The specific working process of this invention is as follows:

[0046] This solution includes multiple energy storage boxes 2 arranged vertically to increase energy storage capacity and save space. A plug 4 is installed at the top of the energy storage box 2, and a socket 41 is installed at the bottom. Connecting the plug 4 and the socket 41 not only enables the connection between different energy storage boxes 2, but also limits the movement of the upper and lower energy storage boxes 2 to prevent them from shaking. The connection between the energy storage box 2 and the central processing box is achieved in the same way.

[0047] By connecting the shell body, closed side plate, closed end plate, upper waterproof sealing gasket, and side waterproof sealing gasket, a sealed connection for multiple battery cells is effectively achieved, which helps with waterproofing. At the same time, a heat sink 6 is set up. In this solution, an aluminum nitride composite coating / graphene composite coating is cold-sprayed on the outside of the heat sink 6. Both graphene and aluminum nitride have high thermal conductivity and heat dissipation capabilities, and aluminum nitride also has strong electrical insulation capabilities and strong adhesion. Combined with the base frame 32 and universal wheels 3, a comprehensive technical effect of waterproofing, heat dissipation, and portability is achieved in an integrated design.

[0048] A heating film is installed at the bottom of the battery cell. On the one hand, it preheats the battery cell before use, which helps the battery cell to quickly enter the working state and protect the battery cell. On the other hand, when the external temperature is detected to be higher than the internal temperature of the storage tank, the heating film works to maintain the internal and external temperature balance and prevent the formation of water vapor or water droplets inside, thus protecting the battery cell.

[0049] Example 2

[0050] This second embodiment is derived from embodiment 1. For the sake of simplification, the lifting and transferring components are not detailed, but this does not affect the implementation of the solution; this is hereby explained.

[0051] See Figures 6-7 The lifting and transfer components are respectively attached to two roller drive components on both sides of the energy storage box 2, a screw assembly for the two roller drive components to move in opposite directions at the same time, and an adjustment component for the two roller drive components to rotate and lift at the same time. The bottom end of the adjustment component is positioned and connected to the outer end of the base.

[0052] The roller drive assembly includes a vertically placed frame 7, multiple horizontally parallel rotating shafts 9 on the frame 7, multiple rollers 8 fixedly mounted on the rotating shafts 9, a synchronous pulley 91 coaxially positioned on the rotating shafts 9, and a synchronous belt meshing with the multiple synchronous pulleys 91. The outer end of one of the rotating shafts 9 is connected to the motor 12. The rollers 8 are made of rubber.

[0053] Under the action of motor 12, the rotating shaft 9 is driven to rotate, and the rotating shaft 9 in turn drives the rollers 8 to rotate. Since multiple rollers 8 are attached to both sides of the energy storage box 2, the energy storage box 2 can be lifted up and moved upward. The rollers are made of rubber, which can generate a large friction force. More preferably, the two motors 12 are connected to the controller to achieve synchronous control.

[0054] More preferably, a limiting plate 17 is attached to the outer side of the timing belt and fixed to the frame 7 by bolts. This limits the outer side of the timing belt and ensures the normal operation of the timing belt and multiple timing pulleys.

[0055] The lead screw assembly includes a horizontally arranged guide post 10 and a lead screw 11, and a rotating plate coaxially fixed to the outer end of the lead screw 11. The guide post 10 and the lead screw 11 pass through the top ends of two frames 7. One end of the guide post 10 is fixedly connected to one of the frames 7, and its other end slides through the other frame 7.

[0056] In use, the screw drive principle is used to manually turn the rotating plate, causing the two frames to move towards each other. It should be noted that the screw 11 has a forward thread and a reverse thread at both ends, with opposite directions of rotation. The forward thread and the reverse thread are connected to the two frames 7 respectively, so that when the screw 11 is turned, the two frames 7 can move towards each other or away from each other. The thread parameters of the forward thread and the reverse thread are the same.

[0057] The adjustment assembly includes a positioning seat 13, guide posts 15 that are vertically fixed at both ends of the positioning seat 13, a spring 16 sleeved on the guide post 15, and a stop block 18 fixedly disposed on the outer end of the guide post 15. The guide post 15 slides through the frame 7, and the stop block 18 is disposed on the outer side of the frame 7.

[0058] The positioning seat 13 and the free end of the lifting cylinder 14 are rotatably connected by bearings, and the bottom end of the lifting cylinder 14 is fixed to the outer end face of the base frame 32 by a connecting rod. The lifting cylinder 14 is located on the outside of the energy storage box 2.

[0059] In use, people can use the bearings to freely rotate the two frames 7 to help move the energy storage box 2 outside the base frame 32 onto the base frame 32.

[0060] The spring 16 limits the movement of the frame 7, ensuring its stability and preventing it from moving arbitrarily. The stop block 18 is used to limit the movement and prevent the frame 7 from slipping out of the guide post 15.

[0061] Equipped with a roller drive assembly, to save manpower when moving the energy storage box, the frame 7 is placed on both sides of the energy storage box, and the rollers 8 are attached to the outside of the energy storage box. Under the action of the lead screw assembly, the frame 7 is tightly attached to the outside of the energy storage box. The motor 12 works, and under the action of compression and friction, the energy storage box moves upward. At this time, human assistance may be required. Finally, the lifting height and the rotation of the energy storage box can be adjusted by the adjustment assembly.

[0062] When the transfer process is completed, the two frames 7 are respectively placed on both sides of the central electrical control box 1 to limit the overall position and ensure the stability of the position.

[0063] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
