[0026] To address the high costs and manpower waste associated with existing factory-return repair methods, this application provides a repair container and a repair vehicle.

[0027] See Figures 1 to 3 A maintenance container includes a container body 10, a detection component 20, a handling component 30, and a power supply component 40. The container body 10 has an internal storage space. The detection component 20 is disposed inside the container body 10, and at least a portion of the detection component 20 is movable to the outside of the container body 10. The detection component 20 is used to detect external electrical devices. The handling component 30 is disposed inside the container body 10 and is capable of extending or retracting into the container body 10. The handling component 30 is used to move the detection component 20 to the outside of the container body 10. The power supply component 40 is disposed inside the container body 10 and is electrically connected to the detection component 20 and the handling component 30, and provides power to the detection component 20 and the handling component 30.

[0028] When battery clusters need testing or repair, the repair container is moved to the vicinity of the clusters requiring testing or repair. The testing component 20 is then moved out of the container 10 using the handling component 30, and the battery clusters are tested or repaired using the testing component 20 located within the container 10. This eliminates the need for manual handling. When equipment or battery clusters in remote locations malfunction or require repair, moving the repair container enables testing and repair services, saving manpower and reducing costs.

[0029] In this application, the maintenance container also includes a tool cabinet 50 located inside the container body 10, and at least a portion of the inspection components 20 can be stored in the tool cabinet 50.

[0030] The testing component 20 includes at least one of the following: energy storage converter, insulation withstand voltage tester, internal resistance tester, joint debugging tester, multimeter, insulation meter, enclosure airtightness tester, liquid cooling airtightness tester, module equalizer, and single cell charging tester.

[0031] Specifically, different tests require different testing tools when testing battery clusters, so there are many types of testing components 20. By setting up a tool cabinet 50, different testing equipment can be sorted and placed inside the cabinet, which not only facilitates the placement and use of testing components 20, but also makes it easier to find testing components 20.

[0032] In this application, the housing 10 has a first side and a second side opposite to each other. The first side is an open side. The conveying assembly 30 is disposed on the first side and can extend out of the housing 10 from the first side. The distance between the power supply assembly 40 and the second side is less than the distance between the power supply assembly 40 and the first side.

[0033] Specifically, by placing the handling component 30 on the opening side of the housing 10, it is convenient to move the testing tools inside the housing 10 to the outside of the housing 10. Since the power supply component 40 occupies a fixed space, placing the power supply component 40 closer to the second side of the housing 10 can reserve more space on the first side of the housing 10. For some tests that need to be prevented from entering the housing 10, the larger operating space facilitates the testing process.

[0034] In this application, there are multiple power supply units 40 and tool cabinets 50, spaced apart along the length of the container 10. By providing multiple tool cabinets 50, different testing components 20 can be categorized and placed, facilitating the retrieval and use of the testing components 20. By providing multiple power supplies, the service life of the maintenance container can be increased. Since most testing equipment is electrically powered, providing multiple power supply units 40 increases the power supply's operating time, thereby reducing the frequency of recharging the maintenance container. This improves efficiency and reduces costs.

[0035] In this application, the maintenance container also includes a heat dissipation component 60, which is disposed inside the container 10 and located on one side of the power supply component 40 to dissipate heat from the power supply component 40 and the detection component 20.

[0036] Specifically, the power supply generates heat during use, and excessively high temperatures may affect its operation. Therefore, a heat dissipation component 60 is installed to cool the interior of the container and prevent excessively high temperatures inside the container 10. Preferably, the heat dissipation component 60 can be a refrigerant, a fan, or something else.

[0037] In this application, the maintenance container also includes a charging component 70, which is located inside the container body 10 and is electrically connected to the power supply component 40. The charging component 70 is used to connect to an external power source to charge the external power source.

[0038] Specifically, the maintenance container can also charge battery clusters. In some scenarios where charging is inconvenient, external devices or batteries can be charged through the charging component 70 and power supply, increasing the container's functionality and meeting various usage scenarios.

[0039] In this application, the handling assembly 30 includes a forklift 31, an overhead crane 32, and a lifting platform 33.

[0040] Specifically, the forklift 31 is a small forklift 31, which can move heavy detection components 20 inside the housing 10, and can also be moved outside the housing 10 for use. The overhead crane 32 is located at the top of the housing 10. In use, it can extend to the outside of the housing 10 via extended slide rails to move heavy detection components 20 out of the housing 10, or to move external battery clusters or detection components 20 into the housing 10, thus facilitating handling. The lifting platform 33 has wheels, and the detection components 20 can be moved onto the lifting platform 33 by the forklift 31 or the overhead crane 32, and then moved to a designated position by the lifting platform 33.

[0041] In this application, the lifting platform 33 includes a base 331, a lifting mechanism, and a support platform 333. The lifting mechanism 332 is mounted on the base 331, and the support platform 333 is mounted on the base 331. The lifting mechanism 332 controls the lifting of the support platform 333.

[0042] The height of the support platform 333 is changed by raising and lowering the lifting mechanism. When the position of the battery cluster to be inspected is different, the height of the support platform 333 can be changed to facilitate inspection at different heights. Preferably, the lifting component 332 can be a scissor lift or a cylinder, etc., to facilitate control and change of the height of the support platform 333.

[0043] In this application, the lifting assembly also includes multiple rollers 334, which are rotatably mounted on the support platform 333. By setting the rollers 334, the detection assembly 20 can be moved on the support platform 333, and the detection assembly 20 and the workpiece to be detected can continue to be aligned and corrected.

[0044] In this application, the lifting assembly also includes a fixing assembly, which is disposed on the support platform 333 to fix the item placed on the support platform 333.

[0045] When testing is required, the testing component 20 needs to be fixed to increase the accuracy of the test and reduce errors. The fixing component can be a strap, a quick-press head, etc., or the testing component 20 can be fixed by limiting the position of a fixing block that is detachably connected to the support platform 333.

[0046] In one implementation, the maintenance container can perform DCB cycles and DCB rework both inside and outside the power station; it is powered by a 30-ton semi-trailer trailer, on which a 40-foot container is fixed. The container contains a set of integrated boost inverter modules, three sets of 261KW outdoor cabinets, an insulation withstand voltage tester, an internal resistance tester, a commissioning tester (computer + CAN box), a multimeter, an insulation meter, a box airtightness tester, a liquid-cooled airtightness tester, a module equalizer, a single cell charging device, a forklift, a lifting device, and a thermal imager.

[0047] Because the maintenance container houses various equipment, it can be used in different scenarios: when performing DCB circulation inside the power station, the power station equipment is used for circulation; when performing DCB circulation outside the power station, a mobile test vehicle is used, which includes the PCS, transformer, power supply, high and low voltage control system, and high voltage cables; DCB rework inside and outside the power station requires battery cluster repair, fire protection system repair, liquid cooling system repair, and electrical system repair; battery cluster repair includes PACK replacement, MOD replacement, EOL testing, airtightness testing, joint commissioning testing, and equalization charging; the maintenance equipment is equipped with a folding canopy + electric forklift 31 transfer + lifting device for inspection. The system includes DCB high and low voltage connections, PACK pull-out and push-in, PACK testing equipment, integrated debugging equipment for cluster-level integrated debugging, DCB liquid injection equipment, and installation and disassembly tools. When a battery cluster needs repair, the overhead crane 32 built into the vehicle lifts the testing equipment, electric forklift 31, tool cabinet 50, and lifting platform 33 to the ground. The electric forklift 31 then transports the equipment to the vicinity of the battery cluster to be tested. The lifting platform 33 is then securely fixed and raised to the position of the PACK to be replaced. The PACK is pulled out by the motor on the lifting platform 33 and then transported to the designated location for testing and repair by the electric forklift 31. The system can also charge other vehicles.

[0048] By mounting the maintenance container on the front of the vehicle to form a maintenance vehicle, it is convenient to transport these devices simultaneously and move them to locations that are inconvenient for inspection, making it easier to maintain the devices at those locations.

[0049] Among them, the maintenance container uses the PCS, transformer, power supply, high and low voltage control system, high voltage cable, etc. to realize DCB circulation; the liquid injection device performs DCB liquid injection; the elevator is used for maintenance and DCB high and low voltage connection and PACK pull-out and push-in; the joint commissioning device performs cluster-level joint commissioning; it can also perform EOL test, airtightness test and other functions.

[0050] The lifting platform 33 features a telescopic design, a load capacity of ≥1.5 tons, and overall dimensions of ≤1980mm (length), ≤1200mm (width), and ≤2.2m (height). The maximum lifting height is 3m, and the minimum lowering height is 0.3m. The platform is supported by rollers 334, with a motor-driven push-pull mechanism in the center. The lifting platform 33 is equipped with casters featuring a pneumatic anti-slip design. The entire unit includes a support mechanism to prevent tilting and shifting when the frame is pulling battery packs. It is compatible with pulling out and pushing in battery packs of different sizes. The lifting platform 33 also features a power-off anti-fall function.

[0051] The gantry crane 32 has a load capacity of ≥1.5 tons inside the container; it adopts a three-axis design, which can move the cargo in three directions: X, Y, and Z; the gantry crane 32 is telescopic or folding type, with a body height of ≤250mm and a length of ≤2.6 meters. The effective stroke of the gantry crane 32 inside the container is ≥2.4 meters, and it can extend ≥2 meters outside the container; the hook can be raised to the inside of the body, and the equipment has a power failure and anti-fall function.

[0052] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0053] 1. When battery clusters need testing or repair, the repair container is moved to the vicinity of the battery cluster requiring repair or testing. The testing component 20 is then moved out of the container 10 using the handling component 30, and the battery cluster is tested or repaired using the testing component 20 located inside the container 10. This eliminates the need for manual handling. When equipment or battery clusters in remote locations malfunction or require repair, moving the repair container enables testing and repair services, saving manpower and reducing costs.

[0054] 2. When testing battery clusters, different tests require different testing tools, so there are many types of testing components 20. By setting up a tool cabinet 50, different testing equipment can be sorted and placed inside the tool cabinet, which not only facilitates the placement and use of testing components 20, but also makes it easier to find testing components 20.
