Description

[0002] Power batteries are a core component of new energy vehicles. With the rapid development of new energy vehicles, there are increasingly more cases of power batteries experiencing insulation abnormalities or even thermal runaway after vehicles have been submerged in water. The water safety of power batteries has become a significant factor restricting the development of new energy vehicles, and how to fully identify and verify the reduction of battery pack risks is a key focus of research and development.

[0003] In related technologies, battery packs are equipped with structural components such as balance valves, high-voltage connectors, and low-voltage connectors, which are mounted to the battery pack casing via mounting brackets. Water leakage in battery packs mainly occurs at the connections between these structural components and the mounting brackets.

[0004] However, most common water wading tests are based on whole vehicle durability tests, which require dedicated test sites. The testing process is time-consuming and labor-intensive, and carries certain safety risks. After the test is completed, the entire battery pack needs to be disassembled and analyzed, resulting in high overall testing costs and long cycles. Summary of the Invention

[0014] Furthermore, the structural components include a balance valve, a high-pressure connector, and a low-pressure connector. The step of replacing multiple structural components with a sealing plug of the simulation test device in a predetermined order includes replacing two of the balance valve, the high-pressure connector, and the low-pressure connector with a sealing plug of the simulation test device in a predetermined order.

[0015] Furthermore, before the step of installing the multiple structural components of the test piece to the multiple mounting interfaces of the mounting piece one by one, the test method also includes: S2, installing the multiple sealing plugs to the multiple mounting interfaces one by one, connecting the simulation box to the inflation pipeline, filling the simulation box with compressed air at a preset pressure, maintaining it for a second preset time, and testing the pressure inside the simulation box using a pressure gauge on the inflation pipeline.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 4 As shown, this embodiment of the invention provides a simulation testing device, which includes a support 10 and a simulation box 20. The support 10 is provided with a first driving member 11 and a second driving member 12. The simulation box 20 has a test component connection surface, and the mounting component 30 of the test component can be sealed and installed at the test component connection surface. The first driving member 11 is driven to the simulation box 20 to move the simulation box 20 vertically, and the second driving member 12 is driven to the simulation box 20 to rotate the simulation box 20 about a vertical axis. A test component for detecting sealing performance is provided inside the simulation box 20.

[0034] Applying the technical solution of this invention, the simulation testing device includes a bracket and a simulation box 20. The mounting component 30 of the component under test (DUT) is installed at the DUT connection surface of the simulation box 20, and the structural component of the DUT is installed on the mounting component 30. A first driving component 11 drives the simulation box 20 to move vertically, immersing the simulation box 20 with the DUT installed in water. A second driving component 12 drives the simulation box 20 to rotate around a vertical axis, thereby simulating the wading driving state of a vehicle. Within a first preset time, a detection component can detect whether water has seeped into the simulation box 20, thus detecting the sealing performance at the connection between the mounting component 30 and the structural component. Compared to existing wading tests, there is no need for a full vehicle test, simplifying the testing process and eliminating safety risks. Furthermore, by using the simulation box 20 to install the DUT, there is no need to disassemble and analyze the battery pack, shortening the testing cycle.

[0035] It should be noted that, in order to ensure the accuracy of the test results, the installation interface of the mounting component 30 needs to be sealed with a sealing plug before the test, and the airtightness test of the simulation box 20 needs to be carried out.

[0036] In this embodiment, the detection element is a capacitive proximity switch for leak detection. The simulation test device also includes a controller mounted on the bracket 10. After the proximity switch detects a leak, the controller automatically drives the simulation box 20 to rise above the water surface and triggers an audible and visual alarm via the first drive element 11.

[0037] The mounting component 30 is installed on the simulation chamber 20 by bolt connection. A sealing ring is provided at the connection between the mounting component 30 and the simulation chamber 20 for sealing.

[0038] In this embodiment, the large-radius rotational motion of the simulation box 20 is used to simulate the equivalent linear motion, thereby enabling the overall footprint of the testing device to be small.

[0039] like Figure 3 As shown, the simulation testing device also includes a sealing plug, which can be installed at the mounting interface 31 of the mounting component 30. The sealing plug can be used to seal the mounting interface of the mounting component 30, thereby sealing the simulation box 20 after the mounting component 30 is installed.

[0040] Before the test begins, all mounting interfaces 31 can be sealed using sealing plugs to allow for individual airtightness testing of the simulation chamber 20. During the test, since there are multiple structural components and mounting interfaces 31 on each mounting component 30, if water leakage occurs after all structural components are installed and a water immersion simulation test is conducted, sealing plugs can be used to seal some mounting interfaces 31, leaving only one structural component to test the connection between each structural component and mounting interface 31 separately.

[0041] In this embodiment, the structural components include a balance valve, a high-pressure connector, and a low-pressure connector. When testing the high-pressure connector and the low-pressure connector, the male and female connectors must be matched and then installed as a whole.

[0042] Specifically, the simulation testing device also includes sealing putty, which is applied to the connection between the sealing plug and the mounting interface 31. The sealing putty seals the connection between the sealing plug and the mounting interface 31 to ensure sealing performance.

[0043] like Figure 2 As shown, an anti-eddy current baffle 21 is provided on the outside of the simulation chamber. The anti-eddy current baffle 21 covers the connection surface of the test piece and has a through hole 22. By using the above-mentioned anti-eddy current baffle 21, some water can flow through and appropriately impact the test piece to simulate the protective function of the bottom guard plate when the battery pack is installed in the vehicle body. At the same time, it can also prevent the rotation of the simulation chamber 20 from causing the water flow to rotate, so that the water flow rotates in one direction, which would reduce the movement speed of the simulation chamber 20 relative to the water flow and affect the test results.

[0044] In this embodiment, water is placed in a pool 40 or a bucket, which can provide wading driving with a water depth of 0 to 500 mm and a static immersion environment simulation of 900 mm. The water in the pool 40 can be mixed with foreign objects such as mud and sand as needed to simulate the composition of real road surface water.

[0045] like Figure 2 As shown, the two ends of the anti-vortex baffle 21 are connected to the upper and lower ends of the simulation chamber 20, respectively. There is an installation gap between the anti-vortex baffle 21 and the surface of the test piece to accommodate the test piece. In the rotation direction of the simulation chamber 20, both ends of the installation gap are open structures 23. Using the aforementioned anti-vortex baffle 21, the open structures 23 and the installation gap allow water to pass smoothly. Simultaneously, the through holes in the anti-vortex baffle 21 also allow water to pass smoothly and create disturbance in the water body, preventing the water body from rotating in one direction.

[0046] In this embodiment, the anti-vortex baffle 21 has a bent structure with a sharp corner connection at the bend.

[0047] like Figure 3 As shown, the support 10 includes a frame 13 and a connecting shaft. A second driving member 12 is mounted on the frame 13, and the connecting shaft extends laterally. The second driving member 12 is driven to the first end of the connecting shaft, causing the connecting shaft to rotate around a vertical axis. A first driving member 11 is mounted on the second end of the connecting shaft. Using the aforementioned support 10, the frame 13 can support the second driving member 12, and the connecting shaft can transmit the power of the second driving member 12 to the simulation box 20 and support the first driving member 11, offering the advantage of a simple structure.

[0048] In this embodiment, the second drive unit 12 is driven by a combination of a servo motor and a reducer. The first drive unit 11 is an electric cylinder.

[0049] like Figure 2 As shown, an observation window 24 is provided on the upper surface of the simulation chamber 20. The observation window 24 allows for observation of water seepage within the simulation chamber 20.

[0050] like Figure 5 As shown, another embodiment of the present invention provides a method for simulating battery pack sealing performance testing. The method is used in the simulation testing device provided above. The method includes: S1, installing the mounting component 30 of the test component to the test component connection surface of the simulation testing device; S3, installing multiple structural components of the test component to the multiple mounting interfaces 31 of the mounting component one by one; S4, using the first driving component 11 of the simulation testing device to drive the simulation box 20 of the simulation testing device to move vertically a preset distance to immerse the simulation box 20 in water, using the second driving component 12 of the simulation testing device to drive the simulation box 20 to rotate around the vertical axis at a preset speed for a first preset time, if the detection component detects water leakage inside the simulation box 20, then stopping the second driving component 12, and using the first driving component 11 to drive the simulation box 20 to move vertically to remove the simulation box 20 from the water, and replacing the multiple structural components with the sealing plugs of the simulation testing device in a predetermined order; S5, repeating step S4. Using the aforementioned simulated battery pack sealing test method, the mounting component 30 is installed at the connection surface of the component under test (DUT) in the simulation box 20, and the structural component of the DUT is installed on the mounting component 30. The first driving component 11 drives the simulation box 20 to move vertically a preset distance, immersing the simulation box 20 with the DUT installed in water. The second driving component 12 drives the simulation box 20 to rotate around the vertical axis at a preset speed, thus simulating the wading driving state of a vehicle. If the testing component does not detect any leakage within the simulation box 20 within a preset time, it indicates that the connection between the structural component and the mounting component 30 is well sealed. If the testing component detects leakage within the simulation box 20, multiple structural components are replaced in a predetermined order using a sealing plug, leaving only one structural component installed on the mounting component 30. The sealing performance of all structural components and their mounting interfaces 31 is tested in a predetermined order until a leak is found. Compared to existing water wading tests, there is no need to test the entire vehicle, which simplifies the testing process and eliminates safety risks. Furthermore, by using the simulation box 20 to install the device under test, there is no need to disassemble and analyze the battery pack, thus shortening the testing cycle.

[0051] Step S4, which involves replacing multiple structural components with sealing plugs from a simulation test device in a predetermined order, includes replacing two of the balance valve, high-pressure connector, and low-pressure connector with sealing plugs from the simulation test device in a predetermined order. By replacing two of the three structural components with sealing plugs, the sealing performance of the remaining structural component and its mounting interface 31 can be tested until a leak is found.

[0052] Specifically, before step S3, which involves installing the multiple structural components of the test piece one-to-one to the multiple mounting interfaces 31 of the mounting component, the test method further includes: S2, installing multiple sealing plugs one-to-one to the multiple mounting interfaces 31, connecting the simulation chamber 20 to the inflation pipeline, filling the simulation chamber 20 with compressed air at a preset pressure, maintaining this pressure for a second preset time, and using a pressure gauge on the inflation pipeline to test the pressure inside the simulation chamber 20. By using step S2, all mounting interfaces 31 can be sealed with sealing plugs, and the air pressure inside the inflated simulation chamber 20 can be measured using a pressure gauge to determine whether the simulation chamber 20 itself meets the test requirements.

[0053] In this embodiment, the pressure of the compressed air is approximately 0.5 MPa. The second preset time is approximately 5 minutes.

[0054] In this embodiment, step S4, which involves using the first driving component to move the simulation box vertically a preset distance to immerse it in water, and using the second driving component 12 of the simulation testing device to rotate the simulation box 20 around the vertical axis at a preset speed for a preset time, includes: S41, if the detection component detects no water leakage inside the simulation box, adjusting the preset distance and using the first driving component 11 to move the simulation box 20 vertically a preset distance to immerse it in water. Through the above step S41, different wading depths of the vehicle can be simulated, making the test results more accurate.

[0055] Specifically, the wading depth of the simulation tank 20 can be 10mm, 50mm, 100mm, 200mm, 300mm, 400mm, and 500mm respectively.

[0056] It should be noted that whether the three structural components are tested simultaneously or a single structural component is tested, the tests must be conducted separately at different wading depths to meet the accuracy requirements of the tests.

[0057] In this embodiment, step S4, which involves using the first driving component to move the simulation box vertically a preset distance to immerse it in water, and using the second driving component 12 of the simulation testing device to drive the simulation box 20 to rotate around the vertical axis at a preset speed for a first preset time, includes: S42, if the detection component detects no water leakage inside the simulation box, adjusting the preset speed and using the second driving component 12 to drive the simulation box 20 to rotate around the vertical axis at the preset speed for a first preset time. Through step S42, different vehicle speeds can be simulated, making the test results more accurate.

[0058] Specifically, the simulated vehicle speeds can be 5 km / h, 10 km / h, 20 km / h, 30 km / h, 40 km / h, and 50 km / h.

[0059] It should be noted that, regardless of whether the three structural components are tested simultaneously or a single structural component is tested, the tests must be conducted separately at different vehicle speeds to meet the required accuracy.

[0060] In this embodiment, by conducting tests under different wading depths and driving speeds, a complete test matrix can be obtained, making the test results more intuitive.

[0061] In another embodiment of the present invention, a computer storage medium is provided for storing a program. When the program runs, it controls the device containing the computer storage medium to execute the simulated battery pack sealing test method described above. A mounting component 30 is installed on the test surface of the simulation box 20. The structural components of the test component are installed on the mounting component 30. A first driving component 11 drives the simulation box 20 to move vertically a preset distance. The simulation box 20, after the test component is installed, is immersed in water. A second driving component 12 drives the simulation box 20 to rotate around a vertical axis at a preset speed, thereby simulating the wading driving state of a vehicle. If the detection component does not detect any leakage within the simulation box 20 within a preset time, the preset speed is adjusted, and the simulation test is repeated to simulate wading conditions at different driving speeds at the same wading depth. If the detection component does not detect any leakage within the simulation box 20, the preset distance is adjusted, and the simulation test is repeated to simulate wading conditions at the same driving speed at different wading depths. If no water leakage is detected within the simulation box 20 after all the above tests are completed, it indicates that the connection between the structural component and the mounting component 30 is well sealed. If water leakage is detected within the simulation box 20 under a certain test condition, multiple structural components are replaced in a predetermined order using sealing plugs, leaving only one structural component installed on the mounting component 30. The sealing performance of all structural components and their mounting interfaces 31 is then tested in a predetermined order until a leak is found. Compared to existing water wading tests, this method eliminates the need for testing the entire vehicle, simplifying the testing process and eliminating safety risks. Furthermore, using the simulation box 20 to install the device under test eliminates the need to disassemble and analyze the battery pack, shortening the testing cycle.

[0062] Another embodiment of the present invention provides an electronic device including a memory and a processor. The memory stores a computer program, and the processor is configured to execute the simulated battery pack sealing test method provided above through the computer program. Compared with existing water wading tests, there is no need to conduct whole-vehicle testing, which simplifies the testing process and eliminates safety risks. Furthermore, by using the simulation box 20 to install the device under test, there is no need to disassemble and analyze the battery pack, thus shortening the testing cycle.
