Technical Field

[0001] The present invention relates to the field of energy storage boxes, and in particular to a charge and discharge test station based on energy storage box detection. Background Art

[0002] In the field of energy storage box production and manufacturing, charge and discharge testing of the energy storage box before leaving the factory is a key link to ensure its performance reliability.

[0003] Currently, existing energy storage box testing stations mostly use decentralized functional zoning. That is, the box loading, assembly, testing, and box unloading areas of traditional testing stations are independent of each other. Therefore, when the energy storage box needs to flow between various processes, it must rely on forklifts or manual transportation, which seriously affects the production rhythm of the entire process and causes the testing time to be too long.

[0004] Therefore, a charging and discharging test station based on energy storage box detection is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a charge and discharge test station based on energy storage box detection to shorten the time required for each process flow, thereby improving test efficiency.

[0006] In order to solve the above technical problems, the present invention provides a charging and discharging test station based on energy storage box detection, comprising a box entry area, an assembly area, a testing and fire protection area, and a box exit area, which are laid on the foundation in sequence and connected in series through multiple tracks;

[0007] An inspection-free zone is connected between the assembly area and the box-outlet area via the track, and is used to guide the energy storage boxes assembled in the assembly area to pass through the testing and fire-fighting area;

[0008] A transport drive mechanism is provided on the track for sequentially transferring the energy storage box between the box entry area, the assembly area, the test and fire protection area, and the box exit area, or between the box entry area, the assembly area, the inspection-free area, and the box exit area;

[0009] The transport drive mechanism includes a tractor moving on the track and a winch traction assembly located at one end of the track and embedded in the foundation;

[0014] The output end of the PCS testing machine is used to connect to the energy storage box for testing;

[0015] The host computer is signal-connected to the high-voltage ring network cabinet and the PCS test machine.

[0016] Furthermore, the fire-fighting mechanism includes a gantry fire-fighting frame erected on the foundation and used to wrap the energy storage box, and drainage channels located on both sides of the track corresponding to the test and fire-fighting area.

[0017] Furthermore, the gantry fire fighting frame includes a support frame with rollers provided at the bottom and a fire fighting water pipe;

[0018] The support frame has a cavity for the energy storage box to pass through and out;

[0019] The fire water pipe is fixedly mounted on the support frame and has a plurality of sprinkler heads and valves for controlling water output;

[0020] Wherein, the plurality of sprinkler heads are all located above the energy storage box.

[0021] Furthermore, the assembly area is connected to the battery warehouse via a conveyor belt for inputting the battery packs into the assembly area.

[0022] Furthermore, it also includes a protective component;

[0023] The protection assembly includes a first rainproof shed, a second rainproof shed and a third rainproof shed;

[0024] The first rainproof shed is arranged in the box entry area;

[0025] The second rainproof shed is arranged in the assembly area;

[0026] The third rainproof shed is arranged in the inspection-free area.

[0032] By setting up a box entry area, assembly area, test and fire protection area and box exit area which are laid on the foundation in sequence and connected in series through multiple tracks, and arranging a transportation drive mechanism including a tractor with a lifting and rotating mechanism and a winch traction assembly on the track, the tractor is driven by a steel cable to move and the tractor is switched at the intersection of two adjacent tracks through the lifting and rotating mechanism, so as to realize the sequential transfer of energy storage boxes between various functional areas, avoiding the production rhythm delay problem caused by traditional decentralized partitioning relying on forklifts or manual transfer, thereby improving the circulation efficiency of energy storage boxes in the test station, ensuring the continuity of production rhythm, shortening the time required for the circulation of each process, and improving testing efficiency.

[0033] In addition, by setting up an inspection-free zone track between the assembly area and the box unloading area, the assembled energy storage box can be guided through the testing and fire protection areas, thereby reducing the time consumption of unnecessary testing processes and further improving the circulation efficiency of the energy storage box in the test station.

Detailed implementation manners

[0040] The charge and discharge test station based on energy storage box detection of the present invention will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present invention.

[0041] Moreover, based on the inspiration of this specification and without generating technical contradictions, those skilled in the art can form new technical solutions through cross-combination of different implementation manners, and such variations should all be regarded as falling within the protection scope of this patent.

[0042] In the following paragraphs, the present invention will be described more specifically by way of example with reference to the attached drawings. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the attached drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0043] As Figures 1 to 3 shown, an embodiment of the present invention provides a charge and discharge test station based on energy storage box detection, including an incoming box area 1, an assembly area 2, a testing and fire protection area 3, and an outgoing box area 4 that are sequentially laid on the foundation and connected in series by a plurality of tracks.

[0044] It should be noted that in this embodiment, the plurality of tracks used to connect the incoming box area 1, the assembly area 2, the testing and fire protection area 3, and the outgoing box area 4 are arranged in a "U" shape to reduce the space occupied by the plurality of functional areas and improve the space utilization rate.

[0045] It should also be noted that the incoming box area 1 and the assembly area 2 share the same track.

[0046] Among them, a non-inspection area 5 is connected between the assembly area 2 and the out-box area 4 through the track, which is used to guide the energy storage box assembled in the assembly area 2 to cross the test and fire protection area 3. That is, when the container does not need to be inspected, it can directly enter the out-box area 4 through the non-inspection area 5, so as to reduce the time consumption of unnecessary test processes and improve the turnover efficiency of the energy storage box in the test station.

[0047] In other embodiments, the non-inspection area 5 can also be used as a spare area for the assembly of the energy storage box and the battery, so as to cooperate with the assembly area 2 to improve the assembly rate of the energy storage box and the battery.

[0048] Among them, a handling driving mechanism 6 is arranged on the track, which is used to transfer the energy storage box in turn between the incoming box area 1, the assembly area 2, the test and fire protection area 3 and the out-box area 4 or between the incoming box area 1, the assembly area 2, the non-inspection area 5 and the out-box area 4. That is, by arranging the handling driving mechanism 6 on each track, the turnover of the energy storage box between each functional area is completed.

[0049] In this embodiment, the handling driving mechanism 6 includes a tractor 61 moving on the track and a winch traction component 62 located at one end of the track and embedded in the foundation.

[0050] The tractor 61 is used to carry the energy storage box. In one example, corner fitting steels are arranged on the tractor 61, and connecting holes for bundling and positioning with the energy storage box are arranged on the corner fitting steels.

[0051] The winch traction component 62 is connected to the tractor 61 through a steel cable, and is used to control the movement of the tractor 61 on the track.

[0052] In one example, the winch traction component 62 is set as a winch.

[0053] It should be particularly noted that since the multiple tracks are arranged in a "U" shape, the adjacent two tracks are vertically arranged. Therefore, during the turnover process of the energy storage box, the moving direction of the tractor 61 needs to be switched. Therefore, the tractor 61 is further defined here to make the turnover process of the energy storage box more convenient and stable.

[0054] Specifically, the tractor 61 has a lifting and rotating mechanism 8, which is used to switch and transfer at the junction of two adjacent tracks.

[0055] In addition, please refer to Figure 5 , in a further embodiment, a specific lifting and rotating mechanism 8 is also proposed to facilitate the rapid control of the tractor 61 to switch directions.

[0056] The lifting and rotating mechanism 8 includes a mounting sleeve 81, a rotating motor 82 and a cylinder 83.

[0057] The mounting sleeve 81 is rotatably mounted at the center of the tractor 61 , and a mounting chamber is formed between the mounting sleeve 81 and the tractor 61 .

[0058] The rotating motor 82 is arranged in the installation chamber, and the output end is connected to the center point of the tractor 61. That is, the rotating motor 82 is used as the rotating drive end to complete the rotation control of the tractor 61. Since the installation sleeve 81 and the tractor 61 are rotatably connected, the rotating motor 82 can complete the function of rotating the tractor 61 while maintaining a relatively static state.

[0059] The cylinder 83 is fixedly mounted on the bottom of the mounting sleeve 81 , and a support pad 84 that abuts against the foundation is fixedly mounted on the output end.

[0060] In addition, when the support pad 84 is supported by the foundation and the cylinder 83 continues to lift, the tractor 61 is separated from the track.

[0061] That is, when the direction of the tractor 61 needs to be switched, the support plate 84 is first lifted by the cylinder 83 to separate the tractor 61 from the track. When the separation reaches a preset height, the rotating motor 82 is controlled to operate. At this time, under the support of the support plate 84, the mounting sleeve 81, the rotating motor 82, the cylinder 83 and the support plate 84 can be regarded as a whole and remain in a fixed state, so that the tractor 61 can be rotated. After the direction switching is completed, the cylinder 83 is controlled to retract, so that the tractor 61 gradually descends to contact with the other track, and the traction is completed with the help of the winch traction assembly 62 set on the other track, thereby realizing the flow of the energy storage box between multiple functional areas.

[0062] In other embodiments, Figure 4 As shown, other lifting and rotating mechanisms 8 can also be used to achieve the flow of the energy storage box between multiple functional areas by limiting the tractor 61. For example, the lifting and rotating mechanism 8 only uses a cylinder 83 and a support pad 84 to enable the tractor 61 to be separated from the track. The driving wheel group 611 of the tractor 61 is configured as a movable structure, that is, the tractor 61 has multiple driving wheel groups 611 for reversing. The driving wheel groups 611 are rotatably connected to the tractor 61 via a connecting shaft 612, so that the driving wheel groups 611 can drive the tractor 61 to turn. A hydraulic cylinder (not shown) is added to control the synchronous reversing adjustment of the multiple driving wheel groups 611 at each corner by means of the hydraulic cylinder, so that the tractor 61 does not need to be rotated and reversed as a whole, avoiding the situation where the rotating motor 82 cannot be driven due to excessive load pressure, thereby achieving the purpose of improving the stability of reversing switching.

[0063] It should be noted that in this embodiment, when the tractor 61 changes direction, it is necessary to manually separate the tractor 61 from the winch traction assembly 62. After the reversal is completed, the tractor 61 is manually connected to the winch traction assembly 62 on the track after the switch to perform subsequent traction work, thereby realizing the circulation of the energy storage box in multiple functional areas.

[0064] In other embodiments, the testing and fire protection area 3 is provided with a charging and discharging mechanism 31 and a fire protection mechanism 32 for testing the energy storage box and fire protection, respectively.

[0065] Specifically, the charging and discharging mechanism 31 includes a high-voltage ring main unit, a PCS test machine and a host computer.

[0066] The high-voltage ring main unit (HMU) connects to the external high-voltage power grid, while its outlet connects to the input of the PCS tester. The HMU provides stable access to the external power grid and power distribution, while also providing circuit protection, ensuring safe transmission and reliable supply of high-voltage power during testing.

[0067] The PCS tester's output is connected to the energy storage box for testing. The PCS tester performs bidirectional conversion of AC and DC power, simulating the actual operating conditions of the energy storage box during charging and discharging. It precisely controls test voltage, current, and power parameters to ensure the authenticity and reliability of test data.

[0068] The host computer is signal-connected to the high-voltage ring main unit and the PCS tester. Through signal interaction, the host computer remotely controls and monitors the high-voltage ring main unit and the PCS tester in real time. It can issue test instructions, collect operational data, and generate test reports with a single click, improving the automation and management efficiency of the test process.

[0069] In a further embodiment, the fire-fighting mechanism 32 includes a gantry fire-fighting frame 321 erected on the foundation and used to wrap the energy storage box, and a drainage channel 322 located on both sides of the track corresponding to the test and fire-fighting area 3.

[0070] By setting up a gantry fire gantry 321, a fire barrier is formed that wraps around the energy storage box, ensuring fire protection coverage throughout the entire testing process. By setting up drainage channels 322 on both sides of the track, the sprinkler system of the gantry fire gantry 321 can quickly discharge firefighting wastewater when in use, preventing water accumulation in the foundation from causing equipment short circuits or track corrosion, thereby ensuring the safety of the test environment and the service life of the equipment.

[0071] In one example, multiple groups of gantry fire-fighting racks 321 are provided, and the multiple groups of gantry fire-fighting racks 321 are arranged in series, that is, a group of gantry fire-fighting racks 321 are provided at the position corresponding to each energy storage box to independently cover and wrap each energy storage box, thereby further ensuring the safety of the test environment.

[0072] like Figure 3 As shown, in this embodiment, the gantry fire fighting frame 321 is further limited to further enhance the fire protection effect.

[0073] Specifically, the gantry fire fighting frame 321 includes a support frame with rollers at the bottom and a fire hose. By providing a support frame that can pass through the rollers, the fire hose can follow the support frame to perform a spraying operation, thereby achieving dynamic protection for the energy storage box, ensuring that there are no blind spots in the fire fighting and providing safety guarantees for energy storage box testing.

[0074] It should be noted that in order to ensure that the support frame does not interfere with the movement of the energy storage box, the shape of the support frame is further limited here. Specifically, the support frame has a cavity for the energy storage box to pass through and out to prevent interference with the movement of the energy storage box.

[0075] In this embodiment, the fire water pipe is fixedly installed on the supporting frame and has a plurality of sprinkler heads and valves for controlling water output.

[0076] It should be noted that the multiple sprinkler heads are all located above the energy storage box so as to be able to accurately spray the inside of the energy storage box and improve the safety protection effect.

[0077] In other embodiments, a conveyor belt is provided to facilitate rapid assembly of batteries and energy storage boxes in assembly area 2. Specifically, assembly area 2 is connected to a battery warehouse via a conveyor belt, which is used to feed battery packs into assembly area 2, thereby increasing the assembly rate of energy storage boxes and batteries.

[0078] In other embodiments, the charge and discharge test station further includes a protective component 7 to enable normal testing operations in rainy weather, thereby improving the scope of application.

[0079] Specifically, the protection assembly 7 includes a first rainproof canopy 71 , a second rainproof canopy 72 and a third rainproof canopy 73 .

[0080] Among them, the first rainproof canopy 71 is set in the box entry area 1, the second rainproof canopy 72 is set in the assembly area 2, and the third rainproof canopy 73 is set in the inspection-free area 5.

[0081] In this embodiment, the first rainproof canopy 71 is configured to be a canopy that can be extended and retracted along the length direction of the track corresponding to the assembly area 2. By configuring the first rainproof canopy 71 as a retractable structure, it is convenient for super-high machinery such as forklifts to enter the box entry area 1 to carry out loading and unloading operations of the energy storage box.

[0082] In addition, the second rain shelter 72 is configured as a fixed steel structure rain shelter, and the third rain shelter 73 is configured as a double-track electric rain shelter.

[0083] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
