Description
Technical Field
[0001] This invention relates to the field of battery testing technology, and more specifically to a battery testing device with an integrated water cooling system. Background Technology
[0002] With the accelerated global energy structure transformation and transportation electrification, new energy batteries, as the core energy carriers in electric vehicles, energy storage systems, and other fields, directly impact the market competitiveness of end products and the safety of users' lives through their performance, safety, and reliability. Against this backdrop, systematic and professional battery testing has become an indispensable and crucial link in the industry chain. The core purpose of battery testing is to ensure that battery products meet stringent safety standards, performance indicators, and regulatory requirements throughout their entire lifecycle through rigorous scientific evaluation methods. This is not only fundamental to preventing serious safety accidents such as thermal runaway and fires and protecting public property, but also an important basis for manufacturers to conduct quality control, optimize product design, and enhance brand reputation. Simultaneously, testing helps promote the advancement of battery technology, facilitates the effective use of resources and environmental protection, and provides technical support for the healthy and sustainable development of the industry. During battery pack testing, it is often necessary to test the heat dissipation performance of the battery pack and its operating status under different temperature environments. This testing process often involves clamping a single battery pack with a fixture for charge and discharge tests. In order to simulate the environment of the battery pack in a real vehicle, a water-cooling structure needs to be connected during its charge and discharge tests. For example, a cooling device for battery testing disclosed in CN222866714U uses two clamping blocks to hold the battery body and has a cooling coil inside the clamping blocks. The cooling coil structure is used to cool the battery body with water, which can effectively simulate the charging and discharging test of the battery in a real vehicle environment. However, there are many types of existing battery packs, which usually require different water-cooling structures. Current testing equipment cannot easily replace battery packs and water-cooling structures as needed, making it difficult to meet the usage requirements during testing. In addition, the hot spots of battery packs of different types and lengths vary during operation. Generally, the main heat dissipation parts of the water-cooling structure need to be aligned with the hot spots of the battery pack to achieve a better heat dissipation effect. However, current battery pack testing equipment does not have the function of testing the impact of the installation position of the water-cooling structure on the heat dissipation of the battery pack, making it difficult to meet the testing requirements for the optimal installation position of the water-cooling structure of the battery pack.

[0022] Example 1: Reference Figures 1 to 11 This invention provides a battery testing apparatus with an integrated water-cooling system, comprising: The housing 1 has a mounting groove for placing the battery pack 11 and a clamping assembly 2 for holding the battery pack 11. The battery pack 11 has a built-in thermistor. Water-cooled plate 3 connected to a circulating cooling mechanism; A battery tester that is electrically connected to the battery pack 11 and the thermistor respectively; An end cover 4 is detachably installed on the housing 1 and covers the mounting groove. The end cover 4 is provided with an adjustment frame 41 that moves along its length and is provided with an adjustment mechanism 5 for adjusting the position of the adjustment frame 41. Rotating frame 6, one end of rotating frame 6 is rotatably connected to adjusting frame 41, rotating frame 6 is provided with mounting frame 61 that moves along its thickness direction, water cooling plate 3 is detachably mounted on mounting frame 61, rotating frame 6 is provided with several elastic members 62 that push the mounting frame 61 downward to drive the water cooling plate 3 to be in close contact with battery pack 11. A movable frame 63 is installed along the length of the rotating frame 6, and the rotating frame 6 is provided with a moving mechanism 7 that drives the movable frame 63 to move. Mounting component 8 is connected to the movable frame 63 and, in conjunction with the movement of the movable frame 63, fixes the rotating frame 6 to the adjusting frame 41. The lifting assembly 9 is connected to the movable frame 63 and, in coordination with the movement of the movable frame 63, adjusts the height position of the mounting frame 61 relative to the rotating frame 6.
[0023] It should be noted that the built-in thermistor in the battery pack 11 is a conventional technical feature of the battery pack 11. Furthermore, using a battery tester to electrically connect to the battery pack 11 and the thermistor within the battery pack 11 via cables to perform charge / discharge tests and temperature detection on the battery pack 11 are also existing conventional techniques, which will not be elaborated upon in this application. The battery tester can be a VO2750 model. The end cover 4 is a frame structure with an opening in the middle, allowing the rotating frame 6 to be flipped out through the opening for easy replacement of the water-cooling plate 3.
[0024] In use, the battery pack 11 is clamped and fixed to the mounting slot of the housing 1 by the clamping assembly 2. The battery pack 11 is fixed by the clamping assembly 2. One end of the housing 1 is provided with a slot for the cables of the battery pack 11 and the thermistor to pass through. The cables of the battery pack 11 and the thermistor are connected to the battery tester. Then, the end cover 4 is placed over the mounting slot, and the rotating frame 6 is flipped up relative to the end cover 4. The water-cooling plate 3 connected to the circulating cooling mechanism is installed on the mounting bracket 61 at the rotating frame 6. Then, the rotating frame 6 is rotated to the adjusting bracket 41. The moving mechanism 7 drives the moving frame 63 to move. During the movement of the moving frame 63, it first works with the mounting component 8 to fix the rotating frame 6 onto the adjusting frame 41. At this time, the position of the adjusting frame 41 can be adjusted by the adjusting mechanism 5 to adjust the position of the water-cooled plate 3 relative to the battery pack 11. Then, the moving mechanism 7 continues to drive the moving frame 63 to move and works with the lifting component 9 and the elastic element 62 to adjust the height position of the mounting frame 61 relative to the rotating frame 6, so that the water-cooled plate 3 at the mounting frame 61 can be pressed tightly against the battery pack 11, and the circulating cooling mechanism and battery are activated. The testing instrument can perform testing work; the end cap 4 can be removed to replace the battery pack 11 as needed, and the clamping component 2 can be used to clamp different models of battery pack 11. It is applicable to the testing of battery pack 11 of various models and sizes and has good versatility. When it is necessary to change different water-cooling structures, the moving mechanism 7 drives the moving frame 63 to move. During the movement of the moving frame 63, the lifting component 9 first lifts the mounting frame 61 relative to the rotating frame 6, so that the water-cooling plate 3 is away from the battery pack 11. This avoids the water-cooling plate 3 accidentally squeezing or scratching the battery pack 11 due to directly flipping the rotating frame 6. The moving mechanism 7 continues to drive the moving frame 63 to move and cooperates with the mounting component 8 to release the fixed state of the rotating frame 6. Then the rotating frame 6 can be flipped up relative to the adjusting frame 41, and the current water-cooling plate 3 can be removed and replaced with another water-cooling plate 3 connected to the circulating cooling mechanism. This facilitates the testing of the installation position of the water-cooling plate 3 and the impact of water-cooling plates 3 with different water-cooling channel structures on the heat dissipation performance of the battery pack 11, and meets the testing requirements of the installation position of the water-cooling plate 3 and the heat dissipation performance of different water-cooling channels.
[0025] It should be noted that the water-cooled plate 3 can be made of an aluminum substrate with good thermal conductivity.
[0026] Among them, the elastic element 62 is a spring, the mounting frame 61 is provided with a number of moving rods 611, the rotating frame 6 is provided with a number of sliding grooves for moving the moving rods 611, the moving rods 611 are provided with abutting plates, the sliding grooves are provided with annular portions for the abutting plates to abut, and each sliding groove is provided with a spring. The springs push the abutting plates to the annular abutting portions to drive the mounting frame 61 to extend relative to the rotating frame 6.
[0027] In some embodiments, the end cap 4 is detachably connected to the housing 1 by means of bolts. Specifically, the end cap 4 is provided with a number of mounting holes and the housing 1 is provided with a number of screw holes. By passing the bolts through the mounting holes and connecting them with the screw holes, the end cap 4 and the housing 1 can be detachably installed. In other embodiments, the bolt tip is provided with a handle that is easy for a person to apply force to rotate, so that the cover plate can be disassembled and assembled directly by hand without the aid of tools.
[0028] In some embodiments, the water-cooled plate 3 has a connecting frame at its edge, the connecting frame has a plurality of mounting holes, and the mounting bracket 61 has a plurality of screw holes, so that bolts can be passed through the mounting holes and connected to the screw holes to achieve detachable installation between the water-cooled plate 3 and the mounting bracket 61.
[0029] In some embodiments, a liner 10 smaller than the battery pack 11 can be placed on the housing 1 to adjust the height of the battery pack 11. It should be noted that since the liner 10 is smaller than the battery pack 11, the liner 10 will not obstruct the movement of the clamping assembly 2 when the clamping assembly 2 clamps the battery pack 11, thus ensuring the normal operation of the clamping work.
[0030] Example 2: Reference Figures 1 to 6 In conjunction with the technical solution of Embodiment 1, in this embodiment, the clamping assembly 2 includes a longitudinal rotating rod 21, a first clamping block 22 and a second clamping block 23. The first clamping block 22 and the second clamping block 23 are respectively movably installed on the housing 1 along the length direction of the housing 1. The longitudinal rotating rod 21 is rotatably disposed on the housing 1 and has a first rotating handle coaxially. The longitudinal rotating rod 21 has a first threaded part and a second threaded part with the opposite direction of the first threaded part. The first clamping block 22 has a first threaded hole that mates with the first threaded part, and the second clamping block 23 has a second threaded hole that mates with the second threaded part.
[0031] By rotating the first handle, the longitudinal rotating rod 21 is driven to rotate. The first threaded part and the second threaded part on the longitudinal rotating rod 21, which rotate in opposite directions, respectively drive the first clamping block 22 and the second clamping block 23 to move closer or further apart, thereby realizing the longitudinal clamping operation of the battery pack 11.
[0032] In some embodiments, the clamping assembly 2 further includes a transverse rotating rod 24, a third clamping block 25, and a fourth clamping block 26. The third clamping block 25 and the fourth clamping block 26 are respectively movably mounted on the housing 1 along the width direction of the housing 1. The transverse rotating rod 24 is rotatably mounted on the housing 1 and has a second rotating handle coaxially. The transverse rotating rod 24 has a third threaded portion and a fourth threaded portion with the opposite direction of the third threaded portion. The third clamping block 25 has a third threaded hole that mates with the third threaded portion, and the fourth clamping block 26 has a fourth threaded hole that mates with the fourth threaded portion.
[0033] By rotating the second handle, the transverse rotating rod 24 is driven to rotate. The third and fourth threaded portions on the transverse rotating rod 24, which rotate in opposite directions, respectively drive the third clamping block 25 and the fourth clamping block 26 to move closer or further apart, thereby achieving the longitudinal clamping operation of the battery pack 11. That is, the transverse and longitudinal clamping operation of the battery pack 11 can be achieved by operating the first and second handles.
[0034] Example 3: Reference Figures 1 to 5 In conjunction with the technical solutions of Embodiment 1 and Embodiment 2, in this embodiment, the adjustment mechanism 5 includes an adjustment screw 51 and an adjustment handle 52 coaxially connected to the adjustment screw 51. The adjustment screw 51 is rotatably mounted on the end cover 4, and the adjustment frame 41 is provided with a threaded hole that is threadedly engaged with the adjustment screw 51.
[0035] In some embodiments, the end cap 4 is provided with a second scale 42 for indicating the position of the adjustment bracket 41. The position of the adjustment bracket 41 can be determined by the second scale 42 on the end cap 4, thereby determining the installation position of the water cooling plate 3 relative to the battery pack 11.
[0036] By rotating the adjusting handle 52, the adjusting screw 51 is driven to rotate. During the rotation of the adjusting screw 51, it can cooperate with the threaded hole on the adjusting frame 41 to drive the adjusting frame 41 to move relative to the end cover 4. By cooperating with the second scale 42 on the end cover 4, the position of the adjusting frame 41 relative to the end cover 4 is adjusted, thereby adjusting the position of the water cooling plate 3 relative to the battery pack 11, so as to meet the heat dissipation performance test requirements of the water cooling plate 3 installation position for the battery pack 11.
[0037] Reference Figures 9 to 11 In some embodiments, the circulating cooling mechanism includes a pump body 31, an inlet pipe 32, an outlet pipe 33, and a radiator 34. Both the radiator 34 and the water-cooled plate 3 are provided with channels for the flow of coolant. The two channels are connected through the outlet pipe 33 and the inlet pipe 32. The pump body 31 is located on the outlet pipe 33 and drives the coolant to circulate between the outlet pipe 33, the radiator 34, the inlet pipe 32, and the water-cooled plate 3.
[0038] The pump body 31 drives the coolant to circulate between the inlet pipe 32, the water-cooled plate 3, the outlet pipe 33, and the radiator 34. The coolant transfers heat from the water-cooled plate 3 to the radiator 34 for heat dissipation. It should be noted that the radiator 34 is a known prior art, which is usually composed of radiator tubes and multiple aluminum heat dissipation fins. A fan 35 can be installed on the radiator 34 to blow away the heat from the heat dissipation fins, further improving the heat dissipation effect. The structure of the radiator 34 and the use of the radiator 34 with the fan 35 to achieve the heat dissipation function of electronic equipment (such as desktop computers, high-end servers and network equipment, etc.) or industrial equipment (such as laser cutting machines, marking machines, medical testing instruments, projectors and LED equipment, etc.) are prior art and will not be described in detail in this application.
[0039] In addition, it should be noted that the inlet pipe 32 and the outlet pipe 33 extend from the opening in the middle of the end cap 4; the pump body 31 and each electrical device in this application can be powered by connecting to a power source or socket via a power supply line. The power supply methods of the above-mentioned electrical devices are conventional technical means and will not be described in detail in this application.
[0040] Example 4: Reference Figures 1 to 5 as well as Figures 7 to 9 In conjunction with the technical solutions of embodiments 1-3, in this embodiment, the moving mechanism 7 includes a driving screw 71 and a driving handle 72. The driving screw 71 is rotatably mounted on the rotating frame 6. The driving handle 72 is connected to the driving screw 71 and is used to drive the driving screw 71 to rotate. The moving frame 63 is provided with a threaded hole that is threadedly engaged with the driving screw 71. The rotating frame 6 is provided with a slide rod 64 for the moving frame 63 to be slidably mounted.
[0041] Specifically, the slide bar 64 is marked with a first scale 641 for indicating the position of the moving frame 63 relative to the rotating frame 6.
[0042] In some embodiments, the first scale 641 on the slide bar 64 includes three red-marked scale lines, which correspond to the positions of "the insertion plate 81 is fully inserted and penetrates the insertion frame 82" (at which time the adjusting rod is located at the top horizontal part 923), "the end of the insertion plate 81 is fully retracted into the insertion frame 82" (at which time the adjusting rod is located at the bottom horizontal part 921), and "the insertion plate 81 is completely removed from the insertion frame 82" (at which time the adjusting rod is located at the top horizontal part 923).
[0043] Specifically, the drive handle 72 is connected to a vertical rod 721 that is rotatably connected to the rotating frame 6 in the vertical direction. The bottom end of the vertical rod 721 is coaxially provided with a first bevel gear 722, and the drive screw 71 is coaxially provided with a second bevel gear 711 that meshes with the first bevel gear 722.
[0044] Manually rotating the drive handle 72 will drive the drive screw 71 to rotate via the vertical rod 721, the first bevel gear 722, and the second bevel gear 711. This will, in turn, engage the screw holes on the movable frame 63 to move the movable frame 63 relative to the rotating frame 6. This will facilitate the adjustment of the installation status of the rotating frame 6 and the height position of the water-cooled plate 3 in conjunction with the installation assembly 8 and the lifting assembly 9.
[0045] Example 5: Reference Figures 1 to 5 as well as Figures 7 to 9 In conjunction with the technical solutions of embodiments 1-4, in this embodiment, the installation component 8 includes a plug plate 81 and a plug frame 82 for the plug plate 81 to be inserted into. The plug plate 81 is located at one end of the movable frame 63, and the plug frame 82 is located at the end of the adjusting frame 41 that is rotatably connected away from the rotating frame 6.
[0046] The moving mechanism 7 drives the moving frame 63 to move the insert plate 81 relative to the insert frame 82, thereby fixing and unlocking the rotating frame 6 relative to the adjusting frame 41. When the insert plate 81 is inserted into the insert frame 82, the rotating frame 6 is fixed to the adjusting frame 41; when the insert plate 81 is moved out of the insert frame 82, the rotating frame 6 is in the unlocked state, and the rotating frame 6 can be rotated out as needed to replace the water cooling plate 3.
[0047] The insert frame 82 is provided with a notch for the inlet pipe 32 and the outlet pipe 33 to rotate and move out.
[0048] In some embodiments, the lifting assembly 9 includes an adjusting plate 91, a guide portion 92, and an adjusting column 93. Adjusting plates 91 are provided on both sides of the movable frame 63, and each adjusting plate 91 has a plurality of guide portions 92. A plurality of adjusting columns 93 are spaced apart on both sides of the mounting frame 61. Each guide portion 92 includes a bottom horizontal portion 921, a middle inclined portion 922, and a top horizontal portion 923. The bottom horizontal portion 921, the middle inclined portion 922, and the top horizontal portion 923 are rotatably connected to the adjusting frame 41 at one end of the rotating frame 6 and face towards the other end of the rotating frame 6. In the secondary connection, several guide sections 92 are used to push against several adjusting columns 93 according to the position of the movable frame 63 to adjust the height position of the mounting frame 61; the positions of the guide sections 92 and the insertion plate 81 are configured as follows: when the insertion plate 81 is fully inserted into the insertion frame 82, the adjusting column 93 is located above the bottom horizontal section 921; when the insertion plate 81 moves in the direction of disengaging from the insertion frame 82, the middle inclined section 922 moves toward the adjusting column 93 and pushes the adjusting column 93 upward; when the insertion plate 81 is completely disengaged from the insertion frame 82, the top horizontal section 923 moves to below the adjusting column 93.
[0049] Working principle: After the rotating frame 6 is fixed to the adjusting frame 41 by the mounting component 8, the insert plate 81 is inserted into and passes through the insert frame 82. When the position of the water-cooled plate 3 needs to be adjusted, the moving frame 63 is moved by the moving mechanism 7, and the insert plate 81 gradually moves out of the insert frame 82. During this process, each adjusting column 93 moves along the lower horizontal part, the middle inclined part 922 and the upper horizontal part 923 respectively. When the end of the insert plate 81 is completely retracted into the insert frame 82, the insert plate 81 still remains in the state of being inserted into the insert frame 82, while the adjusting column 93 moves to the upper horizontal part 923, that is, each adjusting column 93 is lifted, which drives the mounting frame 61 to lift so that the water-cooled plate 3 is kept away from the battery pack 11. At this time, the water-cooled plate 3 and the battery pack 11 are in a state of being ... There is a gap between them. The position of the water-cooled plate 3 relative to the battery pack 11 can be adjusted by adjusting the position of the adjusting frame 41 through the adjusting mechanism 5. After the position of the water-cooled plate 3 is adjusted, the moving frame 63 is driven to reset by the moving mechanism 7, and the insert plate 81 is put back into the insert frame 82. Under the elastic force of the elastic element 62, each adjusting column 93 moves along the top horizontal part 923, the middle inclined part 922 and the bottom horizontal part 921 respectively, until the mounting frame 61 moves back to the position above the bottom horizontal part 921. At this time, the mounting frame 61 drives the water-cooled plate 3 to be pressed back onto the surface of the battery pack 11 under the action of the elastic element 62. The position adjustment of the water-cooled plate 3 can be achieved without disassembling the water-cooled plate 3, and the battery pack 11 will not be damaged during the adjustment process.
[0050] When the water-cooled plate 3 needs to be replaced, the moving mechanism 7 drives the moving frame 63 to move. Each adjusting column 93 moves along the lower horizontal part, the middle inclined part 922 and the top horizontal part 923 respectively, until the insert plate 81 is completely removed from the insert frame 82. Each adjusting column 93 moves to the top horizontal part 923, that is, each adjusting column 93 is lifted, which drives the mounting frame 61 to lift so that the water-cooled plate 3 is kept away from the battery pack 11. At this time, there is a gap between the water-cooled plate 3 and the battery pack 11. Then, the rotating frame 6 is flipped upward from the adjusting frame 41. Since there is a gap between the water-cooled plate 3 and the battery pack 11, the flipping process can avoid the water-cooled plate 3 scratching the battery pack 11. Then the water-cooled plate 3 can be disassembled and replaced.
