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

[0039] Reference Figure 1-Figure 3 As shown, the battery temperature control device 110 includes: a housing 11, a plurality of partitions 12, a plurality of first drive components 13, a main controller 14, a temperature control component 15 and a temperature controller 16. The housing 11 has a heat exchange groove 111 suitable for accommodating insulating oil. The heat exchange groove 111 extends along a first direction. The partition 12 is arranged in the heat exchange groove 111. The normal direction of the partition 12 is parallel to the first direction, and the edge of the partition 12 is sealed with the inner wall of the heat exchange groove 111, so that two adjacent partitions 12 define a heat exchange sub-groove in the heat exchange groove 111. 1111, a first driving component 13 is installed on the shell 11, and multiple first driving components 13 are connected to multiple partitions 12 one by one. The main controller 14 is communicated with each first driving component 13, and the main controller 14 is used to control the first driving component 13 to drive the corresponding partition 12 to move along the first direction. The temperature adjustment component 15 is installed on the shell 11, and the temperature controller 16 is communicated with the temperature adjustment component 15. The temperature controller 16 is used to control the temperature adjustment component 15 to adjust the temperature of any area of ​​the heat exchange slot 111 in the first direction.

[0040] Specifically, the battery temperature control device 110 can be used for battery testing equipment, battery thermal management system research and development equipment, laboratory battery temperature control equipment, etc. The heat exchange tank 111 of the battery temperature control device 110 can accommodate batteries and heat-conducting insulating oil. The temperature of the battery can be changed by heating and cooling the insulating oil, so as to facilitate the detection, testing and verification of the battery.

[0041] The housing 11 of the battery temperature regulating device 110 is a slot structure and has a heat exchange slot 111. The heat exchange slot 111 extends along a first direction. The first direction can be Figure 1 In the left and right directions, the heat exchange groove 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 can be quickly temperature-controlled. In addition, when the battery leaks, the insulating oil can also achieve insulation between the shell 11 and the battery to avoid leakage of the shell 11 and improve the safety of the battery temperature control device 110.

[0042] The partition 12 can be a flat plate structure, and the normal direction of the partition 12 is 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 in parallel in the heat exchange groove 111. At the same time, the edge of the partition 12 is sealed with the inner wall of the heat exchange groove 111, so that two adjacent partitions 12 define a heat exchange sub-groove 1111 in the heat exchange groove 111. The volume of the heat exchange sub-groove 1111 is smaller than the volume of the heat exchange groove 111. The partition 12 can block 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-groove 1111, avoid mutual influence of temperature between adjacent heat exchange sub-grooves 1111, and help improve the stability, accuracy and precision of the test.

[0043] The plurality of first drive components 13 are connected to the plurality of partitions 12 in a one-to-one correspondence, and each first drive component 13 is installed on the housing 11. The first drive component 13 can drive the partition 12 connected thereto to move along the first direction relative to the housing 11. The main controller 14 is connected to each first drive component 13 for communication. The main controller 14 is used to control the first drive component 13 to drive the corresponding partition 12 to move along the first direction. That is, the main controller 14 can drive the corresponding plurality of partitions 12 to move through the plurality of first drive components 13 to change the distance between two adjacent partitions 12 in the first direction, that is, change the size of the heat exchange sub-trough 1111 in the first direction. The heat exchange sub-trough 1111 can be adapted to the size of the battery therein in the first direction, and the size of the heat exchange sub-trough 1111 in the first direction can be slightly larger than the size of the battery in the first direction. For example, in the first direction, the size of the heat exchange sub-trough 1111 is D1, and the size of the battery is D2, 10mm≤D1-D2≤40mm, so as to reduce the volume of the heat exchange sub-trough 1111 and the amount of insulating oil in the heat exchange sub-trough 1111. When adjusting the temperature of the battery, the battery temperature regulating device 110 needs to have a smaller heating and cooling capacity for the insulating oil in the heat exchange sub-trough 1111, which is conducive to quickly adjusting the temperature of the battery and reducing the energy consumption required for temperature regulation.

[0044] The temperature regulating component 15 is installed on the shell 11. The temperature regulating component 15 can perform cooling and heating. The thermostat 16 is communicated with the temperature regulating component 15. The thermostat 16 is used to control the temperature regulating component 15 to adjust the temperature of any area of ​​the heat exchange groove 111 in the first direction. When adjusting the temperature of the battery, the thermostat 16 can control the temperature regulating component 15 to adjust the temperature of the inner wall of the heat exchange groove 111 in the area corresponding to the heat exchange sub-groove 1111 where the battery is located. The temperature of the inner wall of the heat exchange groove 111 in the area can change the temperature of the insulating oil in the heat exchange sub-groove 1111, and then adjust the temperature of the battery through the insulating oil.

[0045] It should be noted that the number of partitions 12 and the first drive components 13 can be greater than two, so that the battery temperature control device 110 can independently control the temperature of multiple batteries at the same time. For example, the number of partitions 12 and the first drive components 13 are four, and the four partitions 12 can separate at least three heat exchange sub-troughs 1111 in the heat exchange tank 111. A battery can be placed in each heat exchange sub-trough 1111. The thermostat 16 can independently control the temperature of the insulating oil in the three heat exchange sub-troughs 1111 through the temperature control component 15 to meet the temperature requirements of the batteries in the heat exchange sub-troughs 1111, thereby improving the utilization efficiency of the battery temperature control device 110.

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

[0047] In some embodiments of the present invention, reference Figure 1 As shown, the battery temperature control device 110 also includes: a visual detection device 171, which is communicatively connected to the main controller 14. The visual detection is used to detect the battery position in the heat exchange slot 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 component 13 to drive the partition 12 to move according to the position information, so that the minimum spacing 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 detection device 171 has a camera 1711, which can collect images in the direction of the slot outside the heat exchange slot 111. The visual detection device 171 can obtain the battery position in the heat exchange slot 111 in the collected image based on the image recognition algorithm to obtain position information. The visual detection device 171 sends the position information to the main controller 14. The main controller 14 can control the first driving component 13 to drive the corresponding partition 12 to move according to the position information, so that the minimum spacing between the partitions 12 on both sides of the battery and the battery in the first direction is a preset distance, and the preset distance can be 5mm~20mm, so that the position of the partitions 12 on both sides of the battery can be automatically adjusted according to the position of the battery in the heat exchange slot 111, so that the size of the heat exchange sub-slot 1111 formed by the partitions 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-slot 1111, and enable the battery to exchange heat with the insulating oil all around, which is conducive to quickly adjusting the temperature of the battery and reducing the energy consumption required for temperature control.

[0049] Optionally, the visual detection device 171 has multiple cameras 1711, and the multiple cameras 1711 are arranged on the shell 11 at intervals along the first direction. Each camera 1711 collects images that can detect different areas of the heat exchange tank 111, or multiple cameras jointly collect images of the heat exchange tank 111. The visual detection device 171 obtains position information after mutual verification and calculation based on the collected images to improve the detection accuracy of the battery position.

[0050] It should be noted that before the battery temperature control device 110 is used, in the first direction, multiple partitions 12 can be evenly divided at the left and right ends of the heat exchange slot 111. When the battery temperature control device 110 is in use, multiple batteries can be placed in the heat exchange slot 111 in sequence. After each battery is placed in, the main controller 14 obtains the position information of the battery through the visual detection device 171, and then controls the first driving component 13 to drive the partition 12 to move, so that each battery is located in the heat exchange sub-slot 1111 that matches 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, the number of partitions 12 and the number of first drive components 13 are four, the four partitions 12 are the first partition, the second partition, the third partition and the fourth partition, and 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 control device 110 has the first partition, the second partition, the third partition and the fourth partition arranged in sequence from left to right, and the first partition and the second partition are located on the left side of the heat exchange tank 111, and the third partition and the fourth partition are located on the right side of the heat exchange tank 111.

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

[0054] Step S1, place the first battery into the middle of the heat exchange groove 111 (i.e., between the second partition and the third partition), the main controller 14 obtains the position information of the first battery through the visual detection device 171, and controls the driving component 2 to drive the second partition to move to the right to a position at a preset distance from the left end of the first battery, and controls the driving component 3 to drive the third partition to move to the left to a position at a preset distance from the right end of the first battery. At this time, the first battery is located in the first heat exchange sub-groove formed between the second partition and the third partition.

[0055] Step S2, place the second battery into the heat exchange groove 111 on the right side of the third partition, the main controller 14 obtains the position information of the second battery through the visual detection device 171, and controls the driving component four to drive the fourth partition to move left to a position at a preset distance from the right end of the second battery. At this time, the second battery is located in the second heat exchange sub-groove formed between the third partition and the fourth partition.

[0056] In step S3, a 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 visual detection device 171, and controls the driving component 1 to drive the first partition to move rightward to a position at a preset distance from the left end of the second battery. At this time, the third battery is located in the third heat exchange sub-groove formed between the first partition and the second partition.

[0057] In step S4, the temperature controller 16 controls the temperature regulating assembly 15 to regulate the temperature of the heat exchange tank 111 and the corresponding areas of the first heat exchange sub-tank, the second heat exchange sub-tank, and the third heat exchange sub-tank, so as to independently regulate the temperature of the first battery, the second battery, and the third battery.

[0058] It should be noted that the partition 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 after the second battery is placed in the heat exchange slot 111, the minimum distance between the second battery and the third partition is greater than the preset distance, the main controller 14 can first drive the fourth partition to move to the left through the driving component four and make the fourth partition push the second battery to the left until the minimum distance between the second battery and the third partition is equal to the preset distance, and then the main controller 14 drives the fourth partition to move to the right through the driving component four to a position at a preset distance from the right end of the second battery.

[0060] Therefore, the battery temperature regulating device 110 can automatically adjust the position of the partition 12 according to the position of the battery. The battery temperature regulating 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 groove 111 is the same as the height of the partition 12 , and the height of the partition 12 is less than the groove depth of the heat exchange groove 111 .

[0062] Specifically, the liquid level of the insulating oil in the heat exchange groove 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-groove 1111 between the two close partitions 12 becomes smaller, and the insulating oil in the heat exchange sub-groove 1111 can overflow from above the partition 12. At the same time, the height of the partition 12 is less than the groove depth of the heat exchange groove 111, that is, the insulating oil overflowing from above the partition 12 can enter the heat exchange sub-grooves 1111 with increased volumes on both sides thereof. The insulating oil will not spill out of the heat exchange groove 111, and the liquid level of each heat exchange sub-groove 1111 can be kept consistent to facilitate the use of the battery temperature control device 110.

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

[0064] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the inner wall of the heat exchange groove 111 is provided with a first guide rail 1112 and a first rack 1113 extending along the first direction, and the first driving component 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 matched with the first guide rail 1112, the first motor 132 and the second motor 135 are both communicatively connected with 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, the first gear 133 is meshed 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 the second gear 136 is meshed with the first rack 1113, wherein, in the first direction, the first slider 131 and the second slider 134 are clamped on both sides of the partition 12.

[0065] Specifically, the first slider 131 cooperates with the first guide rail 1112 in a first direction, the first motor 132 on the first slider 131 can drive the first gear 133 to rotate, and the first gear 133 moves along the first direction under the action of the first rack 1113, so that the first gear 133 drives the first motor 132 and the first slider 131 to move synchronously along the first direction.

[0066] The second slider 134 cooperates with the first guide rail 1112 to guide in the first direction, and 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, so that the second gear 136 drives 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 clamped on both sides of the partition 12, and the first motor 132 and the second motor 135 are both communicatively 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 synchronously to the left or right, so that the first slider 131 and the second slider 134 drive the partition 12 to move left and right along the first direction. The first motor 132 and the second motor 135 can form a dual-motor drive to ensure that the first drive component 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 separately, so as to adjust the spacing distance 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 replace the partitions 12 of different thicknesses. For example, when it is necessary to merge the heat exchange sub-trough 1111, the spacing distance 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 front side wall and the rear side wall are opposite in the front-to-back direction) in the front-to-back direction, the first guide rail 1112 and the first rack 1113 are arranged on the rear side wall, and the front side wall is provided with a third guide rail and a third rack extending along the first direction. The first driving 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 matched with the third guide rail, the fourth motor and the fifth motor are both communicatively connected with the main controller 14, the fourth motor is fixedly arranged on the fourth slider, the fourth gear is fixedly arranged on the output shaft of the fourth motor, the fourth gear is meshed with the third rack, the fifth motor is fixedly arranged on the fifth slider, and the fifth gear is fixedly arranged on the output shaft of the fifth motor. , the fifth gear is meshed with the third rack, wherein in the first direction, the fourth slider and the fifth slider are clamped on both sides of the partition 12, and the third direction is perpendicular to the first direction, thereby, the first drive component 13 clamps the partition 12 on the rear side of the partition 12 through the first slider 131 and the second slider 134, and the first drive component 13 clamps the partition 12 on the front side of the partition 12 through the fourth slider and the fifth slider to prevent the partition 12 from tilting. At the same time, the first drive component 13 can drive the partition 12 to move through four motors to further improve the power of the first drive component 13, reduce the load of each motor, and improve the service life of the first drive component 13.

[0070] In other embodiments of the present invention not shown in the figures, the first driving assembly 13 can also be constructed as a first telescopic rod, which can be electrically or hydraulically driven to extend and retract in the first direction 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 level of the insulating oil to reduce the impact of the structures on the first guide rail 1112 and the first rack 1113 on the partition 12, so that the inner wall positions relative to the heat exchange groove 111 and the partition 12 are leveled, reducing the difficulty of sealing between the edge of the partition 12 and the inner wall of the heat exchange groove 111, and ensuring the reliability of sealing between the edge of the partition 12 and the inner wall of the heat exchange groove 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 driving assembly 13, the sealing sleeve is mounted on the edge of the partition body, and the sealing sleeve is sealed with the inner wall of the heat exchange groove 111.

[0073] Specifically, the partition body can be a plate-like structure with the same cross-sectional shape as the heat exchange groove 111 perpendicular to the first direction, and the partition body can be a heat-insulating material part to reduce the heat exchange of the insulating oil on both sides thereof. The sealing sleeve can be a rubber material part, and the sealing sleeve can be fixedly mounted on the edge of the partition 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 notch of the heat exchange groove 111. The sealing sleeve can fill the gap between the partition 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 partition 12 and the inner wall of the heat exchange groove 111.

[0074] In some embodiments of the present invention, reference Figure 4 As shown, the battery temperature control device 110 also includes: a temperature sensor 172. Each heat exchange sub-slot 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 oil temperature of the insulating oil in the heat exchange sub-slot 1111.

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

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

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

[0078] Specifically, the refrigeration module 151 can be a small evaporator or a semiconductor refrigeration element. When refrigerating, the refrigeration module 151 can reduce the temperature of the position corresponding to the heat exchange tank 111 to reduce the temperature of the insulating oil in the heat exchange tank 111. The thermostat 16 can independently control the refrigeration power of each refrigeration module 151 to achieve the control of the thermostat component 15 to adjust the temperature of any area of ​​the heat exchange tank 111 in the first direction. At the same time, the refrigeration module 151 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 refrigeration module 151 can be installed on the outer side wall opposite to the bottom wall of the heat exchange tank 111 to facilitate the installation and maintenance of the refrigeration module 151.

[0079] The heating module 152 can be a small condenser or a PTC heating element. When heating, the heating module 152 can increase the temperature of the position corresponding to the heat exchange tank 111 to increase the temperature of the insulating oil in the heat exchange tank 111. The thermostat 16 can independently control the heating power of each heating module 152 to achieve the control of the thermostat 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 side 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, thereby realizing independent temperature control of different temperature zones.

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

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

[0083] Multiple partitions 12, multiple adjustment plates 18 and multiple second drive components 19 correspond one to one. The second drive component 19 is installed on the corresponding partition 12, and the second drive component 19 is connected to the corresponding adjustment plate 18. When the partition 12 moves left and right along the first direction, the second drive component 19 and the adjustment 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 driving assembly 19 to drive the corresponding adjustment plate 18 to move, so as to adjust the shielding area of ​​the convection through hole 121 of the adjustment plate 18. The second direction can be Figure 5-Figure 7 In the up-down direction, the adjustment plate 18 is not likely to interfere with the inner wall of the heat exchange groove 111 when moving along the up-down direction.

[0085] When the insulating oil in the heat exchange sub-slot 1111 is independently temperature-controlled, the main controller 14 can drive the adjustment plate 18 to move to a position where the convection flow through hole 121 is completely blocked through the second drive assembly 19, that is, Figure 7 As shown in the position, at this time, the flow holes 121 of the partitions 12 on both sides of the heat exchange sub-trough 1111 are closed, and the insulating oil in the heat exchange sub-trough 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 adjustment plate 18 to move to a position at least partially offset from the flow through hole 121 through the second drive assembly 19, that is, Figure 5 or Figure 6 The position shown in the figure, at this time, the flow hole 121 on the partition 12 is opened to reduce the movement resistance of the partition 12. At the same time, the flow hole 121 makes the heat exchange sub-grooves 1111 on both sides of the partition 12 form a communicating vessel, so that the liquid level in the heat exchange sub-grooves 1111 on both sides of the partition 12 remains unchanged before and after the movement.

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

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

[0089] For another example, according to the experimental requirements, the battery temperature in the heat exchange sub-trough 1111 needs to be maintained at 80°C first and then dropped 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-trough 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-trough 1111 are all blocked by the corresponding adjustment plates 18, that is, the flow holes 121 are closed. After the battery test is completed in the 80°C environment, the adjustment plates 18 on at least one side of the partition 12 of the heat exchange sub-trough 1111 are completely blocked. 8 is driven by the corresponding second driving component 19 to a position at least partially offset from the circulation through hole 121, that is, the circulation through hole 121 is opened, and the room temperature insulating oil outside the heat exchange sub-trough 1111 is quickly heat-exchanged with the insulating oil in the heat exchange sub-trough 1111 through the circulation through hole 121, so that the insulating oil temperature of 80°C in the heat exchange sub-trough 1111 is quickly reduced to close to room temperature (25°C) without consuming energy, and then the circulation through hole 121 is closed, and the temperature regulating component 15 cools the insulating oil close to room temperature in the heat exchange sub-trough 1111 to 20°C.

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

[0091] In some embodiments of the present invention, reference Figure 5-Figure 7As shown, the partition 12 may have a plurality of flow holes 121, and the adjustment plate 18 may have a plurality of adjustment holes 181. When the partition 12 and the adjustment plate 18 are facing each other in a first direction, the plurality of flow holes 121 are connected to the plurality of adjustment holes 181 in a one-to-one correspondence. When the second driving component 19 drives the adjustment plate 18 to move upward in the second direction, the adjustment holes 181 are gradually staggered from the corresponding flow holes 121, and the blocking area of ​​the adjustment plate 18 on the flow holes 121 gradually increases until the adjustment plate 18 completely blocks each flow hole 121.

[0092] In some embodiments of the present invention, reference Figure 5-Figure 7 As shown, the adjustment plate 18 has a second rack 182 extending along the second direction, and the second driving assembly 19 includes: a third motor 191 and a third gear 192, the third motor 191 is connected to the partition 12, the third gear 192 is fixed to the output shaft of the third motor 191, and the third gear 192 is meshed with the second rack 182.

[0093] Specifically, the third motor 191 on the adjustment plate 18 can drive the third gear 192 to rotate through its output shaft, and the third gear 192 drives the second rack 182 to move in the second direction, so that the adjustment plate 18 moves along the second direction relative to the partition 12. The second drive component 19 has a simple structure and high reliability.

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

[0095] According to the battery temperature control device 110 of the embodiment of the present invention, the interior of the heat exchange tank 111 can be divided according to the shape and size of the battery cell through the position-adjustable partition 12, and the size of the heat exchange sub-tank 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 adjusted independently, and the temperature can be accurately controlled according to the actual needs of the single cell. This design improves the adaptability and versatility of the battery temperature control device 110, so that it can flexibly adapt to battery samples of different types and sizes to meet diverse adaptation needs, reduce customization costs, and eliminate the need to specially design different heat exchange tanks 111 for different battery samples, thereby saving production costs.

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

[0097] The second driving component 19 can drive the adjustment plate 18 to move relative to the partition 12 to change the blocking area of ​​the flow hole 121 on the partition 12 by the adjustment plate 18, thereby controlling the opening and closing and flow area of ​​the flow hole 121, and realizing rapid heat complementarity between the heat exchange sub-slots 1111 in different temperature zones, so as to improve the temperature control efficiency and reduce energy consumption.
