Description

Technical Field

[0001] This utility model relates to the field of automotive battery testing technology, and in particular to a quality testing device for new energy vehicle batteries. Background Technology

[0002] Automotive battery testing is a crucial step in ensuring battery performance and safety. Testing primarily includes visual inspection, voltage testing, capacity testing, and internal resistance testing. Visual inspection can detect signs of battery damage, cracks, or corrosion. Voltage testing uses a voltmeter to measure the battery voltage, ensuring it is within the normal range. Capacity testing uses a testing instrument to measure the battery capacity and assess its energy storage capacity. Internal resistance testing measures the battery's internal resistance to determine its efficiency. In addition, there are methods such as start-up testing and discharge testing. Automotive battery testing can promptly identify battery problems, ensuring normal vehicle start-up and operation, improving driving safety, and extending battery life.

[0003] Battery quality testing equipment for new energy vehicles is crucial in the industry. Firstly, it involves a comprehensive inspection of the battery's appearance, confirming the absence of damage, deformation, corrosion, etc., as well as the clarity and completeness of battery markings and the secureness of battery connections, ensuring there is no looseness or damage. Secondly, it includes performance testing, such as capacity testing (determining the battery's maximum and actual usable capacity through constant current charge-discharge testing); voltage testing (measuring the battery voltage with a voltmeter to ensure it is within the normal range); internal resistance testing (measuring the battery's impedance characteristics at different frequencies using methods such as AC impedance spectroscopy to determine battery efficiency); and cycle life testing (assessing the battery's lifespan through repeated charge-discharge cycles to understand the performance degradation during long-term use).

[0004] Traditional battery quality testing methods still rely on manual operation of instruments to measure aspects such as internal resistance, voltage, and charge / discharge capacity, resulting in low measurement efficiency. Furthermore, when testing the chemical properties of the battery, it is difficult to detect its physical properties, such as appearance, clarity and completeness of battery markings, and minor defects on the battery cell casing. The testing focus is relatively limited. Therefore, a new energy vehicle battery quality testing device is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as limited detection direction and low detection efficiency, by proposing a new energy vehicle battery quality testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The device includes a detection board and a battery mounting board. Multiple indicator lights are fixedly connected to the side of the detection board away from the control cabinet. These indicator lights are used to display the location of the faulty battery to assist personnel in testing. A support frame is movably connected between the battery mounting board and the detection board. A control cabinet is fixedly connected to the side of the support frame closest to the battery mounting board. The control cabinet is used to control a motor and a telescopic cylinder. The battery mounting board and the detection board are movably connected. A telescopic cylinder is fixedly connected to the end of the detection board away from the battery mounting board. This telescopic cylinder is used to push the detection board closer to the battery mounting board. Multiple battery slots are formed on the side of the battery mounting board closest to the detection board. These battery slots are used to place the battery cells under test. The multiple battery slots are evenly distributed in an array. Battery cells are movably connected to the inner side of each battery slot.

[0008] The measuring assembly includes a motor mounted on a detection plate, a bidirectional threaded rod, rotating rollers symmetrically mounted on the detection plate, and a scanning head. The rotation of the motor drives the rotation of the two rotating rollers, and the motor drives the bidirectional threaded rod to rotate, thereby driving the scanning head to move repeatedly to perform omnidirectional scanning.

[0009] The above technical solution further includes:

[0010] The telescopic cylinder is fixedly connected to a top plate at the end away from the detection plate. The top plate is fixedly connected to the bracket. The detection plate is slidably connected to the bracket. The battery mounting plate is fixedly connected to the bracket. The bracket is used to support the detection plate and the battery mounting plate.

[0011] Electrode contact plates are symmetrically fixedly connected to the inner side of multiple battery slots. Two of the electrode contact plates make contact with the battery cells together. The voltage, internal resistance, charge and discharge capacity of the battery are detected through the two electrode contact plates.

[0012] The motor is fixedly connected to the detection plate, and the output end of the motor is fixedly connected to the first main flywheel. The detection plate has multiple grooves on the side near the battery mounting plate. The inner side of each of the multiple grooves is rotatably connected to a bidirectional threaded rod. The two scanning heads are threadedly connected to the bidirectional threaded rods and slidably connected to the grooves. By rotating the motor and using the guiding effect of the grooves, the two scanning heads are repeatedly moved by the bidirectional threaded rods.

[0013] The bidirectional threaded rod extends to the outside of the detection plate and is fixedly connected to a first auxiliary flywheel and a second main flywheel at one end near the motor. A first belt is sleeved and connected between the first auxiliary flywheel and the first main flywheel, and the first belt plays a role in transmission.

[0014] Two sets of support columns are symmetrically fixedly connected to the side of the detection plate near the battery mounting plate, and each set of support columns consists of two columns. The inner sides of the two sets of support columns are respectively rotatably connected to a first rotating shaft and a second rotating shaft. The first rotating shaft and the second rotating shaft are used to drive the rotating roller to rotate, thereby driving the battery cell to rotate and assisting the scanning head in scanning.

[0015] The first rotating shaft is fixedly connected to a third main flywheel and a second auxiliary flywheel at one end near the motor. The second rotating shaft is fixedly connected to a third auxiliary flywheel at one end near the motor. A second belt is sleeved and connected between the second main flywheel and the second auxiliary flywheel. A third belt is sleeved and connected between the third main flywheel and the third auxiliary flywheel. The second belt is used for transmission between the second main flywheel and the second auxiliary flywheel. The third belt is used for transmission between the third main flywheel and the third auxiliary flywheel.

[0016] The first rotating shaft and the third auxiliary flywheel are both fixedly connected to the rotating roller, and the two support columns are rotatably connected to the rotating roller. The detection component drives the two scanning heads to scan cyclically by controlling the rotation of the motor, which can accurately identify minute defects on the battery cell shell, such as scratches, dents, white spots, stains, etc., to ensure that each battery meets high standards in appearance, which helps to improve the overall quality of the battery cell.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figures 1-4 As shown, the present invention proposes a new energy vehicle battery quality testing device, including a testing plate 6 and a battery mounting plate 4. Multiple indicator lights 3 are fixedly connected to the side of the testing plate 6 away from the control cabinet 1. The indicator lights 3 are used to display the location of the faulty battery to help the staff test it. A bracket 7 is movably connected between the battery mounting plate 4 and the testing plate 6. A control cabinet 1 is fixedly connected to the side of the bracket 7 near the battery mounting plate 4. The control cabinet 1 is used to control the motor 11 and the telescopic cylinder 5. The battery mounting plate 4 and the testing plate 6 are movably connected. A telescopic cylinder 5 is fixedly connected to the end of the testing plate 6 away from the battery mounting plate 4. The telescopic cylinder 5 is used to push the testing plate 6 closer to the battery mounting plate 4. Multiple battery slots 9 are opened on the side of the battery mounting plate 4 near the testing plate 6. The multiple battery slots 9 are evenly distributed in an array. The battery slots 9 are used to place battery cells 8. The battery cells 8 are movably connected to the inner side of the battery slots 9.

[0028] The measurement assembly includes a motor 11 mounted on the detection plate 6, a bidirectional threaded rod 14, rotating rollers 13 symmetrically mounted on the detection plate 6, and a scanning head 25. The rotation of the motor 11 drives the rotation of the two rotating rollers 13, and the motor 11 drives the bidirectional threaded rod 14 to rotate, thereby driving the scanning head 25 to move repeatedly to perform an all-round scan of the battery cell 8.

[0029] The end of the telescopic cylinder 5 away from the detection plate 6 is fixedly connected to the top plate 2. The top plate 2 is fixedly connected to the bracket 7. The detection plate 6 is slidably connected to the bracket 7. The battery mounting plate 4 is fixedly connected to the bracket 7. The bracket is used to support the detection plate and the battery mounting plate.

[0030] Multiple battery slots 9 are symmetrically fixed with electrode contact plates 10 on their inner sides. Two electrode contact plates 10 are in contact with the battery cell 8. The voltage, internal resistance, charge and discharge capacity of the battery cell 8 are detected by the two electrode contact plates 10.

[0031] In this embodiment, during use, the inspector first places the battery cell 8 inside the multiple battery slots 9 and uses two symmetrically arranged electrode contact plates 10 to tighten the battery cell 8. At this time, the two electrode contact plates 10 are used to test the chemical properties of the battery, such as capacitance, voltage, internal resistance, etc. When a problematic battery is detected, an indicator light 3 is lit. The number of indicator lights 3 is consistent with the number of battery slots 9 and corresponds one-to-one, which facilitates informing the inspector which battery cell 8 is problematic. In the above process, the two electrode contact plates 10 are used to test the chemical properties, voltage, resistance, capacitance, etc. of the battery cell 8. At the same time, the detection component is used to test the physical properties of the battery. When a battery does not meet the standard, the indicator light 3 is lit, thereby reminding the staff and improving the testing efficiency.

[0032] Example 2

[0033] like Figures 1-4 As shown, based on Embodiment 1, the motor 11 is fixedly connected to the detection plate 6, and the output end of the motor 11 is fixedly connected to the first main flywheel 22. The detection plate 6 has multiple grooves 15 on the side near the battery mounting plate 4. The inner side of each groove 15 is rotatably connected to a bidirectional threaded rod 14. The two scanning heads 25 are threadedly connected to the bidirectional threaded rod 14 and slidably connected to the grooves 15. By rotating the motor 11 and using the guiding effect of the grooves 15, the two scanning heads 25 are repeatedly moved by the drive of the bidirectional threaded rod 14.

[0034] The bidirectional threaded rod 14 extends to the outside of the detection plate 6 and is fixedly connected to the first auxiliary flywheel 16 and the second main flywheel 17 at the end near the motor 11. The first auxiliary flywheel 16 and the first main flywheel 22 are connected together to the first belt 18, which plays the role of transmission.

[0035] Two sets of support columns 24 are symmetrically fixedly connected to the side of the detection plate 6 near the battery mounting plate 4, and there are two support columns 24 in each set. The inner sides of the two sets of support columns 24 are respectively rotatably connected to a first rotating shaft 12 and a second rotating shaft 26. The first rotating shaft 12 and the second rotating shaft 26 are used to drive the rotating roller 13 to rotate, thereby driving the battery cell 8 to rotate, and assisting the scanning head 25 to perform scanning.

[0036] The first rotating shaft 12 is fixedly connected to the third main flywheel 21 and the second auxiliary flywheel 20 at one end near the motor 11. The second rotating shaft 26 is fixedly connected to the third auxiliary flywheel 27 at one end near the motor 11. The second main flywheel 17 and the second auxiliary flywheel 20 are connected together to the second belt 19. The third main flywheel 21 and the third auxiliary flywheel 27 are connected together to the third belt 23. The second main flywheel 17 and the second auxiliary flywheel 20 are connected together to the second belt 19. The third main flywheel 21 and the third auxiliary flywheel 27 are connected together to the third belt 23.

[0037] The first rotating shaft 12 and the third auxiliary flywheel 27 are both fixedly connected to the rotating roller 13, and the two support columns 24 are rotatably connected to the rotating roller 13. The third auxiliary flywheel 27 is used to drive the rotating roller 13 to rotate.

[0038] In this embodiment, after the above process is completed, the operator controls the lowering of the telescopic cylinder 5 until the two rotating rollers 13 contact the surface of the battery cell 8. Then, by rotating the motor 11, the rotation of the motor 11 drives the rotation of the first main flywheel 22, the rotation of the first main flywheel 22 drives the movement of the first belt 18, and the movement of the first belt 18 drives the rotation of the first auxiliary flywheel 16.

[0039] The rotation of the first secondary flywheel 16 drives the rotation of the bidirectional threaded rod 14, which in turn drives the rotation of the second main flywheel 17. The rotation of the second main flywheel 17 drives the movement of the second belt 19, which in turn drives the rotation of the second secondary flywheel 20. The rotation of the second secondary flywheel 20 drives the rotation of the first rotating shaft 12, which in turn drives the rotation of the rotating roller 13. Simultaneously, the rotation of the first rotating shaft 12 drives the rotation of the third main flywheel 21, which in turn drives the movement of the third belt 23. The movement of 23 drives the rotation of the third flywheel 27, which in turn drives the rotation of the second rotating shaft 26. The rotation of the second rotating shaft 26 drives the rotation of another rotating roller 13. In this way, the two rotating rollers 13 drive the rotation of the battery cell 8. At the same time, the bidirectional threaded rod 14 is designed with a bidirectional thread. When the bidirectional threaded rod 14 rotates, it drives the two scanning heads 25 to repeatedly scan the battery cell 8. Meanwhile, the two rotating rollers 13 drive and guide the battery cell 8 to rotate, thus completing the all-round scanning of the battery cell 8.

[0040] During the above process, the detection component drives the two scanning heads 25 to scan cyclically by controlling the rotation of the motor 11, which can accurately identify minor defects on the casing of the battery cell 8, such as scratches, dents, white spots, stains, etc., to ensure that each battery meets high standards in appearance, which helps to improve the overall quality of the battery cell 8.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
