Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] The battery temperature regulating device 110 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] Reference Figures 1-3 As shown, the battery temperature regulating device 110 includes: a housing 11, multiple partitions 12, multiple first drive assemblies 13, a main controller 14, a temperature regulating assembly 15, and a temperature controller 16. The housing 11 has a heat exchange groove 111 suitable for containing insulating oil. The heat exchange groove 111 extends along a first direction. The partitions 12 are disposed in the heat exchange groove 111. The normal direction of the partitions 12 is parallel to the first direction, and the edge of the partitions 12 is sealed to the inner wall of the heat exchange groove 111 so that two adjacent partitions 12 define a heat exchange sub-groove within the heat exchange groove 111. 1111, The first drive assembly 13 is installed on the housing 11. Multiple first drive assemblies 13 are connected to multiple partitions 12 in a one-to-one correspondence. The main controller 14 is communicatively connected to each first drive assembly 13. The main controller 14 is used to control the first drive assembly 13 to drive its corresponding partition 12 to move along the first direction. The temperature control assembly 15 is installed on the housing 11. The temperature controller 16 is communicatively connected to the temperature control assembly 15. The temperature controller 16 is used to control the temperature control assembly 15 to adjust the temperature of any area of ​​the heat exchange tank 111 in the first direction.

[0040] Specifically, the battery temperature regulating device 110 can be used in battery testing equipment, battery thermal management system R&D equipment, laboratory battery temperature control equipment, etc. The heat exchange tank 111 of the battery temperature regulating device 110 can hold the battery and thermally conductive insulating oil. By heating and cooling the insulating oil, the temperature of the battery can be changed, so as to facilitate battery testing, experimentation and verification.

[0041] The housing 11 of the battery temperature regulating device 110 has a tank structure and a heat exchange tank 111. The heat exchange tank 111 extends along a first direction, which can be... Figure 1 In the left-right direction, the heat exchange tank 111 is suitable for containing insulating oil. The insulating oil has good thermal conductivity and insulation properties. The battery can be immersed in the insulating oil. After the insulating oil is heated and cooled, the battery temperature can be quickly regulated. In addition, when the battery leaks current, the insulating oil can also achieve insulation between the shell 11 and the battery, avoid leakage of the shell 11, and improve the safety of the battery temperature regulation device 110.

[0042] The partition 12 can be a flat plate structure, with its normal direction parallel to the first direction. The normal direction of the partition 12 is the thickness direction of the partition 12. Multiple partitions 12 can be arranged parallel to each other in the heat exchange tank 111. At the same time, the edge of the partition 12 is sealed to the inner wall of the heat exchange tank 111 so that two adjacent partitions 12 define a heat exchange sub-tank 1111 in the heat exchange tank 111. The volume of the heat exchange sub-tank 1111 is smaller than the volume of the heat exchange tank 111. The partition 12 can prevent the insulating oil on both sides from flowing and exchanging heat with each other, so as to facilitate independent temperature adjustment of the insulating oil in the heat exchange sub-tank 1111 and avoid mutual temperature influence between adjacent heat exchange sub-tanks 1111, which is beneficial to improving the stability, accuracy and precision of the test.

[0043] Multiple first drive components 13 are connected one-to-one with multiple partitions 12. Each first drive component 13 is mounted on the housing 11. The first drive component 13 can drive the partition 12 connected to it to move relative to the housing 11 along a first direction. The main controller 14 is communicatively connected to each first drive component 13. The main controller 14 is used to control the first drive component 13 to drive the partition 12 to move along the first direction. That is, the main controller 14 can drive the corresponding partitions 12 to move through multiple first drive components 13, so as to change the distance between two adjacent partitions 12 in the first direction, that is, change the size of the heat exchange sub-tank 1111 in the first direction. The dimensions of the heat exchange sub-slot 1111 can be adapted to the dimensions of the battery within it in the first direction. The dimensions of the heat exchange sub-slot 1111 in the first direction can be slightly larger than the dimensions of the battery in the first direction. For example, in the first direction, the dimensions of the heat exchange sub-slot 1111 are D1 and the dimensions of the battery are D2, with 10mm ≤ D1 - D2 ≤ 40mm. This reduces the volume of the heat exchange sub-slot 1111 and the amount of insulating oil in it. When adjusting the battery temperature, the battery temperature adjustment device 110 needs to provide less heat and cooling capacity to the insulating oil in the heat exchange sub-slot 1111, which is beneficial for quickly adjusting the battery temperature and reducing the energy consumption required for temperature adjustment.

[0044] Temperature control component 15 is installed on housing 11. Temperature control component 15 can perform cooling and heating. Temperature controller 16 is communicatively connected to temperature control component 15. Temperature controller 16 is used to control temperature control component 15 to adjust the temperature of any area of ​​heat exchange tank 111 in the first direction. When adjusting the temperature of the battery, temperature controller 16 can control temperature control component 15 to adjust the temperature of the inner wall of heat exchange tank 111 in the area corresponding to the heat exchange sub-tank 1111 where the battery is located. The temperature of the inner wall of heat exchange tank 111 in this area can change the temperature of insulating oil in heat exchange sub-tank 1111, thereby adjusting the temperature of the battery through insulating oil.

[0045] It should be noted that the number of separators 12 and first drive components 13 can be greater than two, so that the battery temperature regulating device 110 can simultaneously regulate the independent temperature of multiple batteries. For example, the number of separators 12 and first drive components 13 can both be four. The four separators 12 can be spaced out into at least three heat exchange sub-slots 1111 within the heat exchange tank 111. Each heat exchange sub-slot 1111 can hold one battery. The temperature controller 16 can independently regulate the temperature of the insulating oil in the three heat exchange sub-slots 1111 through the temperature regulating component 15 to meet the temperature requirements of the batteries in the heat exchange sub-slots 1111 and improve the efficiency of the battery temperature regulating device 110.

[0046] According to the battery temperature regulating device 110 of the present invention, the main controller 14 can control the first drive component 13 to drive the corresponding partition 12 to move along the first direction, so as to adjust the size of the heat exchange sub-tank 1111. The temperature controller 16 can control the temperature regulating component 15 to adjust the temperature of any area of ​​the heat exchange tank 111 in the first direction, so as to independently adjust the temperature of the insulating oil in each heat exchange sub-tank 1111. The battery temperature regulating device 110 can be adapted to batteries of different sizes, realize rapid and low-energy temperature regulation of batteries, and has good product competitiveness.

[0047] In some embodiments of the present invention, reference is made to... Figure 1 As shown, the battery temperature control device 110 also includes a visual inspection device 171, which is communicatively connected to the main controller 14. The visual inspection device 171 is used to detect the position of the battery in the heat exchange tank 111 to obtain position information and send the position information to the main controller 14. The main controller 14 is also used to control the first drive assembly 13 to drive the partition 12 to move according to the position information, so that the minimum distance between the partition 12 on both sides of the battery and the battery in the first direction is a preset distance.

[0048] Specifically, the visual inspection device 171 has a camera 1711, which can acquire images from the outside of the heat exchange tank 111 towards the opening. The visual inspection device 171 can obtain the position information of the battery in the heat exchange tank 111 based on the image recognition algorithm. The visual inspection device 171 sends the position information to the main controller 14. The main controller 14 can control the first drive component 13 to drive the corresponding partition 12 to move according to the position information, so that the minimum distance between the partition 12 on both sides of the battery and the battery in the first direction is a preset distance, which can be 5mm to 20mm. Thus, according to the position of the battery in the heat exchange tank 111, the position of the partition 12 on both sides of the battery can be automatically adjusted so that the size of the heat exchange sub-tank 1111 formed by the partition 12 on both sides of the battery is slightly larger than the size of the battery, so as to reduce the amount of insulating oil in the heat exchange sub-tank 1111 and allow the battery to exchange heat with the insulating oil from all sides, which is beneficial to quickly adjust the battery temperature and reduce the energy consumption required for temperature adjustment.

[0049] Optionally, the visual inspection device 171 has multiple cameras 1711, which are arranged at intervals on the housing 11 along a first direction. Each camera 1711 acquires images of different areas of the detectable heat exchange tank 111, or multiple cameras can jointly acquire images of the heat exchange tank 111. The visual inspection device 171 calculates and verifies the acquired images to obtain position information, thereby improving the accuracy of battery position detection.

[0050] It should be noted that before the battery temperature regulating device 110 is used, in the first direction, multiple partitions 12 can be evenly distributed at the left and right ends of the heat exchange tank 111. When the battery temperature regulating device 110 is used, multiple batteries can be placed into the heat exchange tank 111 in sequence. After each battery is placed, the main controller 14 obtains the position information of the battery through the vision detection device 171, and then controls the first drive assembly 13 to drive the partitions 12 to move so that each battery is located in the heat exchange sub-tank 1111 that is adapted to its size.

[0051] For example, there are three batteries that need to be tested for temperature regulation, namely the first battery, the second battery and the third battery. There are four separators 12 and four first drive components 13. The four separators 12 are the first separator, the second separator, the third separator and the fourth separator. The four first drive components 13 are drive component one, drive component two, drive component three and drive component four.

[0052] Before use, the battery temperature regulating device 110 has the first, second, third and fourth partitions arranged from left to right, with the first and second partitions located on the left side of the heat exchange tank 111 and the third and fourth partitions located on the right side of the heat exchange tank 111.

[0053] When using the battery temperature regulating device 110, the following steps are included:

[0054] In step S1, the first battery is placed in the middle of the heat exchange tank 111 (i.e., between the second and third partitions). The main controller 14 obtains the position information of the first battery through the vision detection device 171, and controls the second drive assembly to drive the second partition to move to the right to a position separated from the left end of the first battery by a preset distance, and controls the third drive assembly to drive the third partition to move to the left to a position separated from the right end of the first battery by a preset distance. At this time, the first battery is located in the first heat exchange sub-tank formed between the second and third partitions.

[0055] In step S2, the second battery is placed into the heat exchange tank 111 on the right side of the third partition. The main controller 14 obtains the position information of the second battery through the vision detection device 171 and controls the drive assembly 4 to drive the fourth partition to move to the left to a position that is a preset distance away from the right end of the second battery. At this time, the second battery is located in the second heat exchange sub-tank formed between the third partition and the fourth partition.

[0056] In step S3, the third battery is placed in the heat exchange groove 111 on the left side of the second partition. The main controller 14 obtains the position information of the third battery through the vision detection device 171 and controls the drive assembly to drive the first partition to move to the right to a position that is a preset distance away from the left end of the second battery. At this time, the third battery is located in the third heat exchange groove formed between the first partition and the second partition.

[0057] In step S4, the temperature controller 16 controls the temperature adjustment component 15 to adjust the temperature of the corresponding areas of the heat exchange tank 111 and the first heat exchange sub-tank, the second heat exchange sub-tank, and the third heat exchange sub-tank, so as to achieve independent adjustment of the temperature of the first battery, the second battery, and the third battery.

[0058] It should be noted that the separator 12 can push the battery to move in the first direction to adjust the position of the battery.

[0059] For example, in step S2, if the minimum distance between the second battery and the third separator is greater than a preset distance after the second battery is placed in the heat exchange tank 111, the main controller 14 can first drive the fourth separator to move to the left through the drive component four and push the second battery to the left until the minimum distance between the second battery and the third separator is equal to the preset distance. Then, the main controller 14 can drive the fourth separator to move to the right through the drive component four to a position that is a preset distance away from the right end of the second battery.

[0060] Therefore, the battery temperature control device 110 can automatically adjust the position of the separator 12 according to the position of the battery. The battery temperature control device 110 has a good level of automation and intelligence, making the product more competitive in the battery testing equipment market.

[0061] In some embodiments of the present invention, the liquid level of the insulating oil in the heat exchange tank 111 is the same as the height of the partition 12, and the height of the partition 12 is less than the depth of the heat exchange tank 111.

[0062] Specifically, the liquid level of the insulating oil in the heat exchange tank 111 can be the same as the height of the partition 12. If the two partitions 12 are close to each other, the volume of the heat exchange sub-tank 1111 between the two close partitions 12 becomes smaller, and the insulating oil in the heat exchange sub-tank 1111 can overflow from the top of the partition 12. At the same time, the height of the partition 12 is less than the depth of the heat exchange tank 111, that is, the insulating oil overflowing from the top of the partition 12 can enter the heat exchange sub-tanks 1111 on both sides where the volume increases, and the insulating oil will not spill out of the heat exchange tank 111. Moreover, the liquid level of each heat exchange sub-tank 1111 can be kept consistent to facilitate the use of the battery temperature control device 110.

[0063] In some other embodiments of the present invention, the liquid level of the insulating oil in the heat exchange tank 111 is less than or equal to the height of the partition 12. The partition 12 is provided with an openable and closable flow passage 121 below the liquid level of the insulating oil. When the partition 12 is stationary, the flow passage 121 is closed to prevent the insulating oil in different heat exchange sub-tanks 1111 from flowing and exchanging heat through the flow passage 121, thus ensuring the temperature independence of each heat exchange sub-tank 1111. When the partition 12 moves, the flow passage 121 is opened to reduce the moving resistance of the partition 12. At the same time, the flow passage 121 makes the heat exchange sub-tanks 1111 on both sides of the partition 12 form a communicating vessel, so that the liquid level in the heat exchange sub-tanks 1111 on both sides of the partition 12 remains unchanged before and after the partition 12 moves.

[0064] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 2 As shown, the inner wall of the heat exchange tank 111 is provided with a first guide rail 1112 and a first rack 1113 extending in a first direction. The first drive assembly 13 includes: a first slider 131, a first motor 132, a first gear 133, a second slider 134, a second motor 135, and a second gear 136. The first slider 131 and the second slider 134 are both slidably engaged with the first guide rail 1112. The first motor 132 and the second motor 135 are both communicatively connected to the main controller 14. The first motor 132 is fixed to the first slider 131. The first gear 133 is fixed to the output shaft of the first motor 132 and meshes with the first rack 1113. The second motor 135 is fixed to the second slider 134. The second gear 136 is fixed to the output shaft of the second motor 135 and meshes with the first rack 1113. In the first direction, the first slider 131 and the second slider 134 are sandwiched between the two sides of the partition 12.

[0065] Specifically, the first slider 131 is guided and engaged with the first guide rail 1112 in the first direction. The first motor 132 on the first slider 131 can drive the first gear 133 to rotate. The first gear 133 moves along the first direction under the action of the first rack 1113, thereby causing the first gear 133 to drive the first motor 132 and the first slider 131 to move synchronously along the first direction.

[0066] The second slider 134 is guided and engaged with the first guide rail 1112 in the first direction. The second motor 135 on the second slider 134 can drive the second gear 136 to rotate. The second gear 136 moves along the first direction under the action of the first rack 1113, thereby driving the second motor 135 and the second slider 134 to move synchronously along the first direction.

[0067] The first slider 131 and the second slider 134 are sandwiched on both sides of the partition 12. The first motor 132 and the second motor 135 are both connected to the main controller 14. The main controller 14 can control the output shafts of the first motor 132 and the second motor 135 to rotate synchronously, so that the first slider 131 and the second slider 134 move to the left or right synchronously, thereby driving the partition 12 to move left and right in the first direction. The first motor 132 and the second motor 135 can form a dual-motor drive to ensure that the first drive assembly 13 has sufficient driving force to overcome the resistance of the insulating oil and drive the partition 12 to move.

[0068] It should be noted that the main controller 14 can also control one of the first motor 132 and the second motor 135 to work independently, thereby adjusting the spacing between the first slider 131 and the second slider 134 in the first direction, so as to facilitate the disassembly and assembly of the partition 12, or to replace the partition 12 with one of different thicknesses. For example, when it is necessary to merge the heat exchange sub-tanks 1111, the spacing between the first slider 131 and the second slider 134 in the first direction can be increased, and then the partition 12 can be manually pulled out.

[0069] In some embodiments of the present invention, the inner wall of the heat exchange tank 111 has a third-direction ( Figure 1The first drive assembly 13 comprises a front sidewall and a rear sidewall (in the front-rear direction) opposite each other. A first guide rail 1112 and a first rack 1113 are provided on the rear sidewall. A third guide rail and a third rack extending along the first direction are provided on the front sidewall. The first drive assembly 13 also includes: a fourth slider, a fourth motor, a fourth gear, a fifth slider, a fifth motor, and a fifth gear. The fourth slider and the fifth slider are both slidably engaged with the third guide rail. The fourth motor and the fifth motor are both communicatively connected to the main controller 14. The fourth motor is fixed to the fourth slider, the fourth gear is fixed to the output shaft of the fourth motor, and the fourth gear meshes with the third rack. The fifth motor is fixed to the fifth slider, and the fifth gear is fixed to the output shaft of the fifth motor. The fifth gear meshes with the third rack. In the first direction, the fourth and fifth sliders are clamped on both sides of the partition 12, and the third direction is perpendicular to the first direction. Thus, the first drive assembly 13 clamps the partition 12 on the rear side of the partition 12 through the first slider 131 and the second slider 134, and clamps the partition 12 on the front side of the partition 12 through the fourth and fifth sliders, preventing the partition 12 from tilting. At the same time, the first drive assembly 13 can drive the partition 12 to move through four motors, so as to further improve the power of the first drive assembly 13, reduce the load on each motor, and improve the service life of the first drive assembly 13.

[0070] In other embodiments of the invention, not shown in the figures, the first drive assembly 13 may also be configured as a first telescopic rod, which may be extended or retracted in a first direction by means of electric or hydraulic drive to drive the partition 12 to move.

[0071] In some embodiments of the present invention, the first guide rail 1112 and the first rack 1113 are both located above the liquid surface of the insulating oil to reduce the influence of the structure on the first guide rail 1112 and the first rack 1113 on the partition plate 12, so that the inner wall position of the heat exchange tank 111 opposite to the partition plate 12 is flat, reducing the difficulty of sealing the edge of the partition plate 12 with the inner wall of the heat exchange tank 111, and ensuring the reliability of the sealing fit between the edge of the partition plate 12 and the inner wall of the heat exchange tank 111.

[0072] In some embodiments of the present invention, the partition 12 includes a partition body and a sealing sleeve. The partition body is connected to the corresponding first drive assembly 13, and the sealing sleeve is fitted onto the edge of the partition body and is sealed to the inner wall of the heat exchange tank 111.

[0073] Specifically, the baffle body can be a plate-shaped structure with the same cross-sectional shape as the heat exchange groove 111 perpendicular to the first direction. The baffle body can be an insulating material to reduce heat exchange between the insulating oil on both sides. The sealing sleeve can be a rubber material and can be fitted and fixed to the edge of the baffle body facing the inner wall of the heat exchange groove 111. The inner wall of the heat exchange groove 111 has two side walls opposite to each other in the third direction and a bottom wall opposite to the opening of the heat exchange groove 111. The sealing sleeve can fill the gap between the baffle body and the bottom wall and two side walls of the heat exchange groove 111, thereby ensuring the reliability of the sealing fit between the baffle 12 and the inner wall of the heat exchange groove 111.

[0074] In some embodiments of the present invention, reference is made to... Figure 4 As shown, the battery temperature control device 110 also includes a temperature sensor 172. Each heat exchange sub-tank 1111 is provided with at least one temperature sensor 172. The temperature sensor 172 is communicatively connected to the temperature controller 16. The temperature sensor 172 is used to detect the temperature of the insulating oil in the heat exchange sub-tank 1111.

[0075] Specifically, each partition 12 and / or each first drive assembly 13 is equipped with a temperature sensor 172, or a temperature sensor 172 is installed on the inner wall of the heat exchange tank 111 at a second preset distance in the first direction. The second preset distance may be less than the thickness of the partition 12 in the first direction, so as to ensure that at least one temperature sensor 172 is provided in each heat exchange sub-tank 1111.

[0076] The temperature controller 16 can obtain the temperature of the insulating oil in the heat exchange sub-tank 1111 through the temperature sensor 172, so that the temperature controller 16 can accurately control the cooling and heating capacity of the temperature regulating component 15, so that the temperature of the insulating oil in the heat exchange sub-tank 1111 is consistent with the preset temperature, thereby improving the temperature regulation accuracy of the temperature controller 16.

[0077] In some embodiments of the present invention, reference is made to... Figure 3 As shown, the temperature control component 15 includes: multiple cooling modules 151 and multiple heating modules 152. The multiple cooling modules 151 are evenly spaced at the bottom of the heat exchange tank 111 along a first direction, and each cooling module 151 is communicatively connected to the temperature controller 16. The multiple heating modules 152 are evenly spaced at the bottom of the heat exchange tank 111 along a first direction, and each heating module 152 is communicatively connected to the temperature controller 16.

[0078] Specifically, the refrigeration module 151 can be a small evaporator or a semiconductor refrigeration device. During refrigeration, the refrigeration module 151 can lower the temperature at its corresponding location in the heat exchange tank 111, thereby reducing the temperature of the insulating oil within the heat exchange tank 111. The temperature controller 16 can independently control the refrigeration power of each refrigeration module 151, enabling the temperature control component 15 to adjust the temperature of any region of the heat exchange tank 111 in the first direction. Simultaneously, the refrigeration module 151 installed at the bottom of the heat exchange tank 111 can fully exchange heat with the insulating oil within the heat exchange tank 111. Optionally, the refrigeration module 151 can be installed on the outer wall opposite to the bottom wall of the heat exchange tank 111 for easier installation and maintenance.

[0079] The heating module 152 can be a small condenser or a PTC heating element. When heating, the heating module 152 can raise the temperature of its corresponding position in the heat exchange tank 111, thereby increasing the temperature of the insulating oil in the heat exchange tank 111. The temperature controller 16 can independently control the heating power of each heating module 152, so as to control the temperature regulating component 15 to adjust the temperature of any area of ​​the heat exchange tank 111 in the first direction. At the same time, the heating module 152 installed at the bottom of the heat exchange tank 111 can fully exchange heat with the insulating oil in the heat exchange tank 111. Optionally, the heating module 152 can be installed on the outer wall opposite to the bottom wall of the heat exchange tank 111 to facilitate the installation and maintenance of the heating module 152.

[0080] Reference Figure 3 As shown, at the bottom of the heat exchange tank 111, multiple cooling modules 151 and multiple heating modules 152 are arranged in rows and columns. In the first direction (left-right direction), each row has multiple cooling modules 151 or heating modules 152 arranged at equal intervals. In the third direction (front-back direction), each column has cooling modules 151 and heating modules 152 arranged alternately, so that the temperature control component 15 can accurately control the temperature of any area of ​​the heat exchange tank 111 in the first direction and realize independent temperature control of different temperature zones.

[0081] In some embodiments of the present invention, reference is made to... Figures 4-7 As shown, the separator 12 has at least one flow hole 121, the axis of which is parallel to the first direction. The battery temperature regulating device 110 further includes a plurality of adjusting plates 18 and a plurality of second driving components 19. The plurality of separators 12, the plurality of adjusting plates 18 and the plurality of second driving components 19 correspond one-to-one. The second driving components 19 are installed on the corresponding separators 12 and connected to the corresponding adjusting plates 18. The main controller 14 is also communicatively connected to each second driving component 19. The main controller 14 is also used to control the second driving component 19 to drive its corresponding adjusting plate 18 to move along the second direction to adjust the blocking area of ​​the adjusting plate 18 on the flow hole 121. The second direction is perpendicular to the first direction.

[0082] Specifically, the through hole 121 can penetrate the partition 12 in the thickness direction. The insulating oil on both sides of the partition 12 can flow to each other through the through hole 121 to balance the liquid level of the insulating oil on both sides of the partition 12. It can also enable the insulating oil on both sides of the partition 12 to exchange heat quickly. The main controller 14 can calculate the real-time temperature difference between adjacent heat exchange sub-tanks 1111 through the temperature controller 16 and automatically adjust the moving speed and position of the partition regulating plate 18.

[0083] Multiple partitions 12, multiple adjusting plates 18 and multiple second drive components 19 are corresponding one to one. The second drive component 19 is installed on the corresponding partition 12 and connected to the corresponding adjusting plate 18. When the partition 12 moves left and right along the first direction, the second drive component 19 and the adjusting plate 18 corresponding to the partition 12 also move synchronously with the partition 12.

[0084] In a second direction perpendicular to the first direction, the main controller 14 can control the second drive assembly 19 to drive its corresponding adjusting plate 18 to move, thereby adjusting the blocking area of ​​the adjusting plate 18 on the flow through hole 121. The second direction can be... Figures 5-7 In the vertical direction, the adjusting plate 18 is less likely to interfere with the inner wall of the heat exchange tank 111 when it moves in the vertical direction.

[0085] When independently adjusting the temperature of the insulating oil in the heat exchange sub-tank 1111, the main controller 14 can drive the adjusting plate 18 to move to a position where the passage hole 121 is completely blocked via the second drive assembly 19. Figure 7 At the position shown, the flow holes 121 of the partition plates 12 on both sides of the heat exchange sub-slot 1111 are closed, and the insulating oil in the heat exchange sub-slot 1111 cannot flow and exchange heat with the external insulating oil through the flow holes 121.

[0086] When the partition 12 moves along the first direction, the main controller 14 can drive the adjusting plate 18 to move to a position at least partially offset from the flow through hole 121 via the second drive assembly 19. Figure 5 or Figure 6 At the position shown, the flow through hole 121 on the partition 12 is opened to reduce the moving resistance of the partition 12. At the same time, the flow through hole 121 makes the heat exchange sub-tanks 1111 on both sides of the partition 12 form a communication, so that the liquid level in the heat exchange sub-tanks 1111 on both sides of the partition 12 remains unchanged before and after the partition 12 is moved.

[0087] When the battery in the heat exchange sub-slot 1111 needs to undergo large temperature difference regulation such as alternating heating and cooling, the main controller 14 can drive the adjustment plate 18 to move to a position that is at least partially offset from the flow through hole 121 via the second drive assembly 19. Figure 5 or Figure 6At the position shown, at this time, the flow hole 121 on the partition plate 12 on at least one side of the heat exchange sub-tank 1111 is open. The insulating oil in the heat exchange sub-tank 1111 and the external insulating oil can flow and exchange heat with each other through the flow hole 121, thereby realizing the rapid adjustment of the temperature of the heat exchange sub-tank 1111 and reducing the energy consumption of temperature adjustment.

[0088] For example, when the temperature of the insulating oil in one heat exchange sub-tank 1111 is 80°C and the temperature of the insulating oil in the adjacent heat exchange sub-tank 1111 is 20°C, if it is necessary to adjust the temperature difference between the two to less than 5°C, the regulating plate 18 can be controlled to gradually open to reduce its blocking area on the flow through hole 121, so that the insulating oil in the two heat exchange sub-tanks 1111 can flow and exchange heat with each other through the flow through hole 121, thereby gradually reducing the temperature difference between the two. The second drive assembly 19 can dynamically adjust the moving speed and position of the regulating plate 18 to precisely control the heat exchange rate of the two heat exchange sub-tanks 1111, and avoid test errors or heat waste caused by excessively rapid temperature changes.

[0089] For example, according to experimental requirements, the battery temperature in the heat exchange sub-slot 1111 needs to be maintained at 80°C first, and then reduced to 20°C. When the battery temperature regulating device 110 is working, the temperature regulating component 15 can first heat the insulating oil in the heat exchange sub-slot 1111 from room temperature (25°C) to 80°C. At this time, the flow holes 121 on the partitions 12 on both sides of the heat exchange sub-slot 1111 are all blocked by the corresponding regulating plates 18, that is, the flow holes 121 are closed. After the battery is tested in an 80°C environment, the regulating plates 121 on at least one side of the partition 12 of the heat exchange sub-slot 1111 are closed. 8 is driven by the corresponding second drive component 19 to a position at least partially offset from the flow through hole 121, that is, the flow through hole 121 is opened, and the room temperature insulating oil outside the heat exchange sub-slot 1111 undergoes rapid heat exchange with the insulating oil inside the heat exchange sub-slot 1111 through the flow through hole 121, thereby rapidly reducing the temperature of the insulating oil in the heat exchange sub-slot 1111 from 80°C to close to room temperature (25°C) without consuming energy. Then the flow through hole 121 is closed, and the temperature regulating component 15 cools the insulating oil in the heat exchange sub-slot 1111 to close to room temperature to 20°C.

[0090] Therefore, the main controller 14 can adjust the blocking area of ​​the regulating plate 18 on the flow through hole 121 through the second drive component 19 to realize the opening and closing function of the flow through hole 121, and adjust its flow area when the flow through hole 121 is open. When the temperature is adjusted by alternating between hot and cold, the flow through hole 121 can be opened to perform rapid temperature adjustment and reduce energy consumption.

[0091] In some embodiments of the present invention, reference is made to... Figures 5-7As shown, the partition 12 may have multiple flow through holes 121, and the adjusting plate 18 has multiple adjusting through holes 181. When the partition 12 and the adjusting plate 18 are facing each other in the first direction, the multiple flow through holes 121 and the multiple adjusting through holes 181 are connected in a one-to-one correspondence. When the second driving assembly 19 drives the adjusting plate 18 to move upward in the second direction, the adjusting through holes 181 and the corresponding flow through holes 121 are gradually offset, and the blocking area of ​​the adjusting plate 18 on the flow through holes 121 gradually increases until the adjusting plate 18 completely blocks each flow through hole 121.

[0092] In some embodiments of the present invention, reference is made to... Figures 5-7 As shown, the adjusting plate 18 has a second rack 182 extending in the second direction, and the second drive assembly 19 includes a third motor 191 and a third gear 192. The third motor 191 is connected to the partition plate 12, and the third gear 192 is fixed to the output shaft of the third motor 191. The third gear 192 meshes with the second rack 182.

[0093] Specifically, the third motor 191 on the adjusting plate 18 can drive the third gear 192 to rotate through its output shaft. The third gear 192 drives the second rack 182 to move in the second direction, thereby causing the adjusting plate 18 to move relative to the partition 12 in the second direction. The second drive assembly 19 mechanism is simple and has high reliability.

[0094] In other embodiments of the invention, not shown in the figures, the second drive assembly 19 may also be configured as a second telescopic rod, which may be electrically or hydraulically driven to extend and retract in the second direction to drive the adjustment plate 18 to move.

[0095] According to an embodiment of the present invention, the battery temperature regulating device 110, through the position-adjustable partition 12, allows the interior of the heat exchange tank 111 to be divided according to the shape and size of the battery cell. The size of the heat exchange sub-tanks 1111 can be flexibly adjusted to improve the space utilization of the heat exchange tank 111. At the same time, the temperature of the insulating oil in each heat exchange sub-tank 1111 can be independently adjusted, enabling precise temperature control according to the actual needs of the battery cell. This design improves the adaptability and versatility of the battery temperature regulating device 110, allowing it to flexibly adapt to battery samples of different types and sizes to meet diverse adaptation needs, reduce customization costs, and eliminate the need to design different heat exchange tanks 111 for different battery samples, thus saving production costs.

[0096] Each heat exchange sub-tank 1111 is equipped with a temperature sensor 172. The temperature control component 15 can adjust the temperature of different locations in the heat exchange sub-tank 111 in zones, so as to achieve independent adjustment of the temperature of the insulating oil in each heat exchange sub-tank 1111. The temperature sensor 172 can monitor the temperature change inside each heat exchange sub-tank 1111 in real time, so that the temperature controller 16 can accurately adjust the temperature, so that each heat exchange sub-tank 1111 can maintain the required constant temperature, avoid temperature interference between different heat exchange sub-tanks 1111, effectively reduce errors and instability factors in the temperature control process, and improve the reliability and accuracy of experimental results.

[0097] The second drive assembly 19 can drive the adjustment plate 18 to move relative to the partition 12, thereby changing the area of ​​the adjustment plate 18 blocking the flow through hole 121 on the partition 12. This allows control over the opening and closing of the flow through hole 121 and the flow area, enabling rapid heat complementarity between heat exchange sub-slots 1111 in different temperature zones, thereby improving temperature regulation efficiency and reducing energy consumption.
