Technical Field
[0001] This utility model relates to the field of automotive battery testing technology, specifically a battery thermal management testing device. Background Technology
[0002] In the field of automotive battery testing technology, battery thermal management testing is a crucial step in evaluating battery performance and safety. Especially in electric vehicles and new energy vehicles, the operating temperature of the battery system directly affects the vehicle's range and battery life. To ensure the battery's thermal performance during real-world use, it is typically necessary to conduct temperature control tests under simulated environments, including simulated cooling and heating. These tests not only need to simulate the battery's heat dissipation under various operating conditions but also its performance in high- or low-temperature environments, thus providing data support for battery design and optimization.
[0003] Existing battery thermal management testing fixtures often suffer from narrow applicability. Most testing equipment is designed for battery systems of specific sizes and shapes, resulting in poor adaptability. When testing different models or sizes of batteries, different testing fixtures are usually required, leading to increased testing costs and reduced efficiency. Furthermore, traditional testing fixtures struggle to accurately simulate temperature control at battery heat dissipation points, which affects the accuracy of test results. In addition, existing equipment does not accurately simulate airflow within the battery system during testing, frequently resulting in airflow contact with other battery surfaces, thus compromising the objectivity of the test.
[0004] Because existing technologies struggle to simulate directional airflow cooling or heating at the bottom of the battery under test, the airflow easily comes into contact with other battery surfaces during testing, interfering with the results and failing to comprehensively and accurately reflect the battery's thermal management performance in real-world applications. Therefore, existing testing equipment needs further improvement in adaptability, accuracy, and ease of operation to meet the increasingly demanding battery testing requirements of the evolving electric vehicle industry.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0029] like Figures 1-4 As shown in the figure, a battery thermal management testing device provided in this embodiment of the present invention includes a support base 1 and a battery under test 7. Support feet 5 are provided at the four corners of the lower surface of the support base 1.
[0030] The upper surface of the support base 1 is provided with a storage groove 10, and the lower surface of the support base 1 is provided with a plurality of ventilation holes 11, which are connected to the storage groove 10.
[0031] A battery tray 8 is centrally located inside the storage recess 10, meaning that the center line of the battery tray 8 is collinear with the center line of the storage recess 10. The battery 7 to be tested is placed on the surface of the battery tray 8. Several sealing blocks 9 are provided on all four sides inside the storage recess 10. The height of the sealing blocks 9 is the same as the depth of the storage recess 10, and the thickness of the battery tray 8 is less than the depth of the storage recess 10.
[0032] After filling all four sides of the storage recess 10 with several sealing blocks 9, a ventilation area is formed inside the storage recess 10. The length of the ventilation area should be the same as the length of the battery 7 being tested, and the width of the ventilation area should be the same as the width of the battery 7 being tested, that is, the battery 7 being tested should just cover the top of the ventilation area.
[0033] The surface of the support base 1 is provided with a cover 4. The length inside the cover 4 is greater than the length of the storage groove 10, and the width inside the cover 4 is greater than the width of the storage groove 10.
[0034] In one embodiment of this utility model, the dimensions of the support base 1 include 2690×1620×170mm (length×width×height) and 2600×1100×160mm (length×width×height). The dimensions of the storage groove 10 are 1300×1100×160mm (length×width×depth), and it is used in conjunction with the battery tray 8. The dimensions of the battery tray 8 are 1200×1000×150mm (length×width×thickness), and it is used to support the battery 7 being tested. The dimensions of the cover 4 are 2350×1500×610mm (length×width×height).
[0035] The height of the sealing block 9 is the same as the depth of the storage groove 10 to ensure that the sealing block 9 can completely fit the inner walls of the storage groove 10. The width and length of the sealing block 9 match the inner edge of the storage groove 10 to ensure that it can effectively fill the gaps around the storage groove 10, so that the battery under test 7 is tightly fitted with the sealing block 9 around its perimeter, forming a uniform ventilation area.
[0036] When performing thermal management tests on the battery under test 7, the battery tray 8 and the battery under test 7 on top of it are first placed in the center of the storage groove 10. At this time, the battery tray 8 is completely placed inside the storage groove 10, and the bottom part of the battery under test 7 is also embedded in the storage groove 10, ensuring that there is a certain gap between its front, back, left and right sides and the inner wall of the sealing block 9.
[0037] Next, sealing blocks 9 are placed around the inside of the storage recess 10, so that they fit tightly against the inner wall of the storage recess 10 until the gaps around the perimeter are completely filled. After this filling process, the battery under test 7 is tightly attached to the surface of the sealing blocks 9, thus ensuring that there are no gaps around the battery.
[0038] Then, the cover 4 is placed on the support base 1. During the subsequent thermal management test, the airflow enters through the ventilation hole 11 at the bottom of the support base 1. However, because the tested battery 7 is tightly fitted with the sealing block 9, the airflow can only contact the bottom surface of the tested battery 7 and cannot pass through the ventilation hole 11 to enter the cover 4 and contact the other surfaces of the battery.
[0039] The above technical solution enables directional airflow cooling or heating simulation of the bottom of the battery under test (7), ensuring that other surfaces are not disturbed by external airflow during the test, thus more accurately simulating the thermal management conditions of the battery in actual applications. This design is simple in structure, easy to operate, and suitable for thermal management testing of batteries of different sizes, exhibiting strong versatility and adaptability.
[0040] In this embodiment, a magnet 12 is provided inside the sealing block 9, and two adjacent sealing blocks 9 are attracted together by the magnet 12. This design facilitates the rapid assembly and disassembly of the sealing blocks, improving the convenience and stability of installation. When testing different battery sizes, the sealing blocks can be flexibly adjusted and fixed in position, thereby reducing adjustment time and improving testing efficiency. This design is suitable for testing various types of batteries and has broad application prospects, especially in the field of electric vehicle battery testing, where it can significantly reduce the complexity of manual operation.
[0041] In this embodiment, the surface of the cover 4 is provided with several handles 3. The design of these handles makes the cover 4 easier to move, install, and remove, allowing operators to more easily control its position and avoid damage to the battery system caused by improper operation. This design makes the testing process more user-friendly, improves operational safety, and is suitable for frequent battery system testing scenarios, especially when it is necessary to test battery performance multiple times under different temperature and environmental conditions.
[0042] In this embodiment, a wire hole 2 is provided on the side of the cover 4. The wire hole 2 is used to connect the test wiring harness of the battery system, enabling data acquisition and control via external devices during thermal management testing of the battery, while maintaining the airtightness of the cover 4. This design can effectively prevent interference from the external environment on the test results and ensure the accuracy of the test data. This design is suitable for various performance evaluations of battery systems and helps to improve the scientific nature and reliability of the test.
[0043] In this embodiment, lifting grooves 6 are provided on both sides of the lower surface of the support base 1. The design of the lifting grooves 6 facilitates the movement of the support base 1 using forklifts or other handling equipment, thereby enabling convenient transportation of the battery system and testing equipment. This is very useful in laboratory and factory environments, especially when frequent movement of testing fixtures is required for different experiments, which can significantly improve work efficiency and reduce labor intensity.
[0044] In this embodiment, the support base 1 and the cover 4 are made of polystyrene or nylon. Polystyrene and nylon materials have excellent thermal insulation properties and durability, effectively blocking the influence of external temperature changes on the battery system, thereby providing a more stable testing environment. Furthermore, these materials are lightweight, reducing the overall weight of the testing equipment and facilitating movement and installation. This design shows promising application prospects in battery thermal management testing that requires precise temperature control, while also extending the service life of the testing device, making it suitable for long-term use testing fixtures.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
