[0003] In the prior art, when testing the insulation performance of an energy storage air cooling plate, the test is generally completed by connecting a test instrument to a conductive part and making the conductive part contact with the surface insulation layer of the energy storage air cooling plate. This process mostly relies on the operator to manually move the conductive part to a specific test position.

[0004] However, the existing technology relies on manual operation to locate the conductive parts, which is not only inefficient, but also the detection results are easily affected by the detection point and the stability of the operation, resulting in errors in the detection results. This is particularly insufficient in applications that require high-precision detection. Secondly, the existing detection method has high skill requirements for operators, which increases the technical threshold and operation difficulty. In addition, there are two detection modes for energy storage air cooling plates: single-sided insulation detection and double-sided insulation detection. When using the existing technology to perform single-sided and double-sided insulation detection on the energy storage air cooling plate, the switching process of single-sided and double-sided insulation detection is complicated and the operation is cumbersome.

DETAILED DESCRIPTION

[0057] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0058] The energy storage air cooling plate 300 is a device used to dissipate heat in an electric energy storage system, and is particularly suitable for systems that require effective heat dissipation to maintain performance and safety, such as battery packs for electric vehicles or large battery storage systems. This cooling technology uses air as a cooling medium to reduce the temperature of the equipment with the help of fans or natural air flow. It is a relatively simple and economical method of heat dissipation. The energy storage air cooling plate 300 is usually made of a material with good thermal conductivity, such as aluminum or copper, which can quickly absorb heat from a heat source (such as a battery cell) and transfer the heat to the air through the plate. In the application of the energy storage air cooling plate 300, the surface-coated insulating layer is an important design consideration, which is mainly to ensure the safety and functionality of the system. It is the key to ensure the safe, stable and long-term operation of electrical equipment.

[0059] like Figure 1-4 As shown, an insulation detection device for an energy storage air cooling plate 300 proposed in a preferred embodiment of the present application includes a base plate 100, an energy storage air cooling plate 300, a conductive foam 400, a pressing plate 500, a first conductive member 600, a second conductive member 700 and a third conductive member 800.

[0060] The bottom plate 100 includes a first plane 110 , and the first plane 110 has an insulating property.

[0061] The base plate 100 provides a bearing base for the insulation monitoring device. In addition to the first plane 110, the base plate 100 also has a second plane on the side away from the first plane 110. The second plane is parallel to the first plane 110. The second plane provides placement conditions for the base plate 100. When the base plate 100 is installed on the workbench 200, the second plane is in contact with and parallel to the surface of the workbench 200. The surface of the workbench 200 is usually set to a horizontal state in the prior art, so that the second plane and the first plane 110 are also parallel to the horizontal plane, thereby providing conditions for the stable placement of the energy storage air-cooled plate 300.

[0062] The shape of the bottom plate 100 can be embodied as a rectangular plate, a square plate, a circular plate or other special-shaped plates in a specific implementation. The shape of the bottom plate 100 is not specifically limited here, and it only needs to meet the requirement of stably placing the bottom plate 100. Specifically, taking the bottom plate 100 as a rectangular plate as an example, as shown in the figure, the shape of the first plane 110 and the shape of the second plane in the rectangular plate are both rectangular to match the shape of the energy storage air cooling plate 300. It can be understood that the length and width of the first plane 110 should be greater than the length and width of the rectangular energy storage air cooling plate 300 to be tested, and the dimensions of bottom plates 100 of other shapes should also meet this requirement.

[0063] In a specific implementation, the material of the bottom plate 100 can be an insulating material so that the first plane 110 has an insulating property, or an insulating material is coated on one side of the bottom plate 100, and the side of the bottom plate 100 coated with the insulating material is the first plane 110. These insulating materials include polymer composite materials, ceramic materials, and glass fiber reinforced plastics (GFRP), etc., wherein specific examples of polymer composite materials may include epoxy resin, polyimide (PI), polytetrafluoroethylene (PTFE), etc. The insulating property of the first plane 110 of the bottom plate 100 can avoid interference with the detection result of the insulation detection device due to its own conductivity.

[0064] The base plate 100 is usually installed on the surface of the workbench 200 using fasteners such as bolts and screws. While the base plate 100 is tightly connected to the surface of the workbench 200, it is also convenient for subsequent disassembly, assembly and replacement of the insulation detection device.

[0065] The conductive foam 400 is disposed on a side of the energy storage air cooling plate 300 away from the bottom plate 100 .

[0066] The conductive foam 400 in the insulation detection device proposed in this embodiment is mainly used to establish a stable and uniform electrical contact between the first conductive member 600 and the energy storage air cooling plate 300, and due to the soft foam structure of the conductive foam 400, during the insulation detection process of the energy storage air cooling plate 300, the conductive foam 400 can also be applied with a certain pressure to make itself in close contact with the object being tested, so that it can adapt to the irregular structure of the surface of the energy storage air cooling plate 300 and fill the tiny gap between the two, thereby reducing the contact resistance, ensuring the uniform transmission of the test current or voltage, and improving the accuracy and repeatability of the test. Moreover, whether it is a flat or slightly curved energy storage air cooling plate 300, the conductive foam 400 can provide an effective contact solution.

[0067] The shape of the conductive foam 400 can be embodied as a rectangular foam sheet, a square foam sheet, a round foam sheet or other special-shaped foam sheets in the specific implementation. The shape of the conductive foam 400 is not specifically limited here, and it only needs to meet the requirement of covering the side of the energy storage air cooling plate 300 away from the bottom plate 100. Specifically, taking the conductive foam 400 cut into a rectangular foam sheet as an example, as shown in the figure, the shape of the conductive foam 400 facing the bottom plate 100 is a rectangular surface, and the size of the rectangular surface should be larger than the corresponding size of the side of the energy storage air cooling plate 300 away from the bottom plate 100, so as to adapt to the shape and size of the energy storage air cooling plate 300.

[0068] The material structure of the conductive foam 400 can be embodied as a porous foam structure in a specific implementation method. This structure can be open-cell or closed-cell, customized according to the use requirements. Among them, the pores of the open-cell foam are interconnected, providing better air permeability and softness, and are suitable for applications that require a certain ventilation effect. Each pore of the closed-cell foam is closed, providing better water resistance and sealing, and is suitable for environments that require waterproofing or higher structural strength. The basic material of the conductive foam 400 is usually polyurethane or polyethylene, and these substrates are specially treated to add conductive particles (such as carbon black, metal powder or conductive polymers) to give the foam conductive properties.

[0069] The conductive foam 400 is usually arranged in a fitting manner on the side of the energy storage air cooling plate 300 away from the base plate 100, and the side of the conductive foam 400 away from the energy storage air cooling plate 300 is usually subjected to pressure applied by the pressing plate 500 to make the conductive foam 400 fit tightly with the surface of the energy storage air cooling plate 300.

[0070] The pressing plate 500 is disposed on the side of the conductive foam 400 away from the bottom plate 100 , and a through hole is opened on the pressing plate 500 . The first conductive member 600 is disposed in the through hole, and the side of the first conductive member 600 facing the bottom plate 100 abuts against the side of the conductive foam 400 away from the bottom plate 100 .

[0071] The side of the pressing plate 500 facing the bottom plate 100 is a third plane, and the third plane is in contact with the side of the conductive foam 400 facing away from the bottom plate 100, so as to apply a force directed to the energy storage air cooling plate 300 to the conductive foam 400, so that the side of the conductive foam 400 facing the bottom plate 100 is closely fitted with the side of the energy storage air cooling plate 300 facing away from the bottom plate 100, so as to ensure good electrical contact between the two while reducing the possibility of a gap between the conductive foam 400 and the energy storage air cooling plate 300, thereby reducing the contact resistance caused by the gap. It should be noted that the pressure applied by the pressing plate 500 to the conductive foam 400 can be provided by the weight of the pressing plate 500 itself, or by an external force perpendicular to the third plane acting on the pressing plate 500, and then acting on the conductive foam 400 through the pressing plate 500.

[0072] The first conductive member 600 is installed in the through hole on the pressing plate 500. The first conductive member 600 has a fourth plane, and the fourth plane is in contact with one side of the conductive foam 400, so that the first conductive member 600 is electrically connected with the conductive foam 400. The first conductive member 600 is installed in the through hole, which reduces the detection steps. When the insulation performance of the energy storage air-cooling plate 300 is detected, it is only necessary to lay the conductive foam 400 in contact with one side of the energy storage air-cooling plate 300, and to make the pressing plate 500 and the opposite side of the conductive foam 400 in contact, so that the first conductive member 600 and the conductive foam 400 can be electrically connected, reducing the impact of manual intervention on the detection results. It should be noted that the side of the first conductive member 600 facing the conductive foam 400 protrudes from the side of the pressing plate 500 facing the conductive foam 400, so as to ensure that the first conductive member 600 is in full contact with the conductive foam 400.

[0073] The shape of the pressing plate 500 can be embodied as a rectangular plate, a square plate, a circular plate or other special-shaped plates in the specific implementation. The shape of the pressing plate 500 is not specifically limited here, and it only needs to meet the requirements of covering the conductive foam 400. Specifically, taking the pressing plate 500 as a rectangular plate as an example, as shown in the figure, the third plane of the pressing plate 500 is a rectangle to match the shape of the conductive foam 400 and the energy storage air cooling plate 300, and the length and width of the third plane should be greater than the length and width of the conductive foam 400 to ensure that when the insulation detection device is in use, when the pressing plate 500 covers the conductive foam 400, it can evenly apply pressure to the side of the conductive foam 400 away from the energy storage air cooling plate 300, further ensuring the fit between the conductive foam 400 and the energy storage air cooling plate 300, and the size of the pressing plate 500 of other shapes should also meet the corresponding requirements of the rectangular plate.

[0074] The shape of the first conductive member 600 can be reflected as a cylindrical member in a specific implementation, and the specific shape of the first conductive member 600 must at least satisfy the requirement of having a fourth plane that can fit tightly with the conductive foam 400. As shown in the figure, the first conductive member 600 takes a cylinder as an example, the fourth plane is an end face of the cylinder, the first conductive member 600 is inserted into the through hole, and the other end of the first conductive member 600 facing away from the fourth plane is constructed with a terminal for connection to an external device.

[0075] The material of the pressing plate 500 can be embodied as an insulating material in a specific implementation so that the third plane has an insulating property, or an insulating material is coated on one side of the pressing plate 500, and the pressing plate 500 coated with the insulating material is the third plane. These insulating materials include polymer composite materials, ceramic materials, and glass fiber reinforced plastics (GFRP), etc., wherein specific examples of polymer composite materials can include epoxy resin, polyimide (PI), polytetrafluoroethylene (PTFE), etc. It can be understood that the insulating property of the third plane of the pressing plate 500 can avoid interference with the detection result of the insulation detection device caused by the conductivity of the pressing plate 500 itself.

[0076] In a specific implementation, the material of the first conductive member 600 can be aluminum, copper, nickel, silver-plated material, stainless steel or gold-plated copper, because these materials have good electrical conductivity and oxidation resistance, and can provide stable electrical performance and a long service life.

[0077] The pressing plate 500 can be separately provided from the conductive foam 400, or can be integrally provided with the conductive foam 400. Taking the pressing plate 500 and the conductive foam 400 as an example, the two can be connected by bonding and fastener connection, so that the conductive foam 400 can be connected to the pressing plate 500 as a whole, and can also be quickly replaced after the conductive foam 400 is worn.

[0078] The first conductive component 600 is installed in the through hole, and can be divided into two types: non-detachable and detachable. Among them, non-detachable means that the first conductive component 600 is connected to the pressure plate 500 as a whole, and the connection methods of the two include welding, integral forming and other connection methods, while the detachable connection includes connection through fasteners and threaded connection and other methods. Taking threaded connection as an example, as shown in the figure, when the first conductive component 600 is a cylinder, a thread is opened on its circumference, and an internal thread that is compatible with the thread on the circumference of the cylinder is tapped in the through hole of the pressure plate 500, so that the first conductive component 600 can be installed in the through hole by threaded connection.

[0079] The second conductive member 700 is disposed between the energy storage air cooling plate 300 and the conductive foam 400 , and is electrically connected to the energy storage air cooling plate 300 . The side of the second conductive member 700 facing away from the bottom plate 100 has insulating properties to limit conduction between the second conductive member 700 and the conductive foam 400 .

[0080] The second conductive member 700 has a fifth plane. When the second conductive member 700 is sandwiched between the conductive foam 400 and the energy storage air cooling plate 300, the fifth plane is tightly fitted with the side of the energy storage air cooling plate 300 away from the bottom plate 100, so that the second conductive member 700 and the energy storage air cooling plate 300 are electrically conductive. The second conductive member 700 partially extends outside the conductive foam 400 and the energy storage air cooling plate 300, and is also constructed as a terminal to facilitate connection with external equipment. In addition, when the second conductive member 700 and the first conductive member 600 are connected to the external detection equipment at the same time, the insulation test of the energy storage air cooling plate 300 away from the bottom plate 100 can be realized, that is, the single-sided insulation performance test of the energy storage air cooling plate 300. It should be noted that the side of the second conductive member 700 facing away from the bottom plate 100 is configured to have better insulation properties in order to prevent the second conductive member 700 from being conductively connected to the conductive foam 400 to avoid affecting the test results of the single-sided insulation performance of the energy storage air cooling plate 300.

[0081] The shape of the second conductive member 700 can be embodied as a plate or strip in a specific implementation so that it has a larger coverage area, especially for the fifth plane. Taking the second conductive member 700 in a strip shape as an example, as shown in the figure, the strip-shaped second conductive member 700 has a wider contact with the energy storage air cooling plate 300, thereby improving the reliability of the connection. The insulating property of the second conductive member 700 on the side away from the energy storage air cooling plate 300 is embodied in the shape and structure as an insulating layer, which completely covers the side of the second conductive member 700 away from the energy storage air cooling plate 300 to prevent the second conductive member 700 from contacting the conductive foam 400, and the insulating layer can be either an insulating coating coated on one side of the second conductive member 700, or an insulating sheet made of insulating material, which is fixedly connected to the side of the second conductive member 700 away from the energy storage air cooling plate 300.

[0082] The material of the second conductive member 700 can be embodied as aluminum, copper, nickel, silver-plated material, stainless steel or gold-plated copper in a specific implementation manner, because these materials have good conductivity and oxidation resistance, and can provide stable electrical performance and a long service life. The insulating properties of the second conductive member 700 on the side away from the energy storage air cooling plate 300 are embodied in the material as polymer composite materials, ceramic materials and glass fiber reinforced plastic (GFRP), etc. Specific examples of polymer composite materials may include epoxy resin, polyimide (PI), polytetrafluoroethylene (PTFE), etc.

[0083] The second conductive member 700 is clamped between the conductive foam 400 and the energy storage air cooling plate 300. At this time, the second conductive member 700 is subjected to the force applied by the pressure plate 500 through the conductive foam 400 and the reaction force fed back to itself by the energy storage air cooling plate 300, so as to ensure that the second conductive member 700 is clamped and fastened, and avoid the second conductive member 700 from moving during the insulation test and affecting the test results.

[0084] The third conductive member 800 is disposed between the energy storage air cooling plate 300 and the bottom plate 100 , and the third conductive member 800 is electrically connected to the energy storage air cooling plate 300 .

[0085] The third conductive member 800 has a sixth plane. When the third conductive member 800 is clamped between the energy storage air cooling plate 300 and the bottom plate 100, the sixth plane is tightly fitted with the side of the energy storage air cooling plate 300 facing the bottom plate 100 to achieve conduction between the third conductive member 800 and the energy storage air cooling plate 300. The third conductive member 800 partially extends outside the bottom plate 100 and the energy storage air cooling plate 300, and is also constructed as a terminal to facilitate connection with external equipment. In addition, when the third conductive member 800 and the first conductive member 600 are connected to the external detection equipment at the same time, the insulation test of the energy storage air cooling plate 300 from the side away from the bottom plate 100 to the side of the energy storage air cooling plate 300 facing the bottom plate 100 can be achieved, that is, the double-sided insulation performance test of the energy storage air cooling plate 300. It should be noted that the reason why the side of the second conductive member 700 facing away from the bottom plate 100 is configured to have better insulation properties is to prevent the second conductive member 700 from being conductive with the conductive foam 400, so as to avoid affecting the detection results of the double-sided insulation performance of the energy storage air cooling plate 300.

[0086] The shape and structure of the third conductive member 800 is embodied in a planar or strip shape in a specific implementation manner so as to have a larger coverage area, especially for the sixth plane. As shown in the figure, taking the third conductive member 800 in a strip shape as an example, the planar or strip shape design helps to ensure extensive contact with the bottom plate 100 and improve the reliability of the connection.

[0087] The material of the third conductive member 800 is embodied in a specific implementation manner as aluminum, copper, nickel, silver-plated material, stainless steel or gold-plated copper, because these materials have good electrical conductivity and oxidation resistance, and can provide stable electrical performance and a long service life.

[0088] The third conductive member 800 includes two types: non-detachable and detachable. The non-detachable type means that the third conductive member 800 is connected to the base plate 100 as a whole, and the connection methods of the two include welding, one-piece molding and other connection methods, while the detachable connection includes connection through fasteners and bonding and other methods. Taking bonding as an example, as shown in the figure, when the third conductive member 800 is strip-shaped, its side away from the energy storage air cooling plate 300 is bonded to the side of the base plate 100 facing the energy storage air cooling plate 300, thereby fixing the third conductive member 800 on the base plate 100, so that when the energy storage air cooling plates 300 are tested in batches, there is no need to adjust the third conductive member 800, so as to improve the detection efficiency and reduce the influence of manual intervention on the detection results.

[0089] It should be noted that when the thickness of the strip-shaped or planar third conductive member 800 is relatively thin, there is no need to consider the gap between the base plate 100 and the energy storage air cooling plate 300. However, when the strip-shaped or planar third conductive member 800 has a certain thickness, it is necessary to place the third conductive member 800 close to the energy storage air cooling plate 300 on the base plate 100 to address the stability issues and the problem of deformation and damage of the third conductive member 800 after being compressed. To address this problem, an embedding groove for accommodating the third conductive member 800 may be provided on the side of the base plate 100 facing the energy storage air cooling plate 300. The depth of the embedding groove is slightly smaller than the thickness of the third conductive member 800, so that the side of the third conductive member 800 facing away from the base plate 100 slightly protrudes from the side of the base plate 100 facing the energy storage air cooling plate 300. This ensures electrical conductivity between the third conductive member 800 and the energy storage air cooling plate 300 while reducing the influence of the energy storage air cooling plate 300 on the third conductive member 800.

[0090] The insulation detection device for the energy storage air cooling plate 300 includes a single-sided insulation detection state and a double-sided insulation detection state. When the insulation detection device is in the single-sided insulation detection state, the first conductive member 600 is connected to a first test end (not shown in the figure) of a testing instrument (not shown in the figure), and the second conductive member 700 is connected to a second test end (not shown in the figure) of the testing instrument to test the insulation performance of the side of the energy storage air cooling plate 300 away from the base plate 100. When the insulation detection device is in the double-sided insulation performance detection state, the first conductive member 600 is connected to the first test end of the testing instrument, and the third conductive member 800 is connected to the second test end of the testing instrument to test the insulation performance from the side of the energy storage air cooling plate 300 away from the base plate 100 to the side of the energy storage air cooling plate 300 close to the base plate 100.

[0091] The insulation detection device for the energy storage air-cooled plate 300 has a through hole opened on the pressure plate 500 and a first conductive member 600 installed therein. At the same time, a second conductive member 700 and a third conductive member 800 are introduced between the conductive foam 400 and the energy storage air-cooled plate 300 and between the energy storage air-cooled plate 300 and the base plate 100, respectively, thereby reducing the interference of external factors on the detection results. In addition, by optimizing the connection relationship between the conductive members in the insulation detection device, rapid switching between single-sided insulation detection and double-sided insulation detection modes is achieved, effectively solving the problems of low efficiency and easy errors caused by manual operation in the prior art, and achieving the effect of enhancing the adaptability of the insulation detection device, the efficiency and accuracy of the detection. In addition, the technical threshold of insulation detection is further reduced, so that the insulation detection device can be applied to a wider range of applications, especially in the field requiring high-precision and high-efficiency insulation detection, which significantly improves the safety and reliability of the product.

[0092] In some embodiments, an insulation detection device for an energy storage air-cooled plate 300 also includes a testing instrument (not shown in the figure), the testing instrument includes the first test end and the second test end mentioned above, the testing instrument also includes an output end and a receiving end, the output end is connected to the first conductive member 600 through the first test end, the receiving end is connected to the second test end, and can be selectively connected to the second conductive member 700 or the third conductive member 800 through the second test end.

[0093] The test instrument is embodied in a specific implementation as a withstand voltage tester, a multifunctional instrument capable of performing insulation resistance and withstand voltage tests. For example, the TOS9300 series is a multifunctional withstand voltage tester suitable for high voltage insulation testing (supporting test voltages up to 5kV). It can provide accurate voltage output and stable current measurement, and is very suitable for insulation testing requiring high precision. The first test terminal and the second test terminal of the test instrument can both be regarded as wire clamps.

[0094] When the energy storage air cooling plate 300 is conducting a single-sided insulation test, the output end of the test instrument is connected to the first conductive member 600 through the first test end, and the receiving end of the test instrument is connected to the second conductive member 700 through the second test end. This connection method ensures that the current flows from the first conductive member 600 to the second conductive member 700, passing through one side of the energy storage air cooling plate 300, so as to achieve the purpose of measuring the insulation performance of one side of the energy storage air cooling plate 300. The test instrument will apply a preset voltage difference between the first conductive member 600 and the second conductive member 700 in the test room. The voltage level should be set according to the material properties and insulation requirements of the energy storage air cooling plate 300, usually between several hundred and several thousand volts. The current state will change according to the insulation performance. The smaller the current, the better the insulation performance. During the single-sided test, the test instrument will record the current passing through the energy storage air cooling plate 300, calculate the resistance value, and compare it with the set safety standard to determine whether the insulation of the surface meets the requirements. In addition, the test instrument can also perform a withstand voltage test and record the magnitude of the current during the withstand voltage test. By analyzing the recorded magnitude of the current, it can be determined whether there is a breakdown or arc on one side of the energy storage air cooling plate 300.

[0095] When the energy storage air cooling plate 300 is subjected to double-sided insulation testing, the output end of the test instrument is still connected to the first conductive member 600 through the first test end, and the receiving end is connected to the third conductive member 800 through the second test end, thereby allowing current to pass through the entire thickness of the energy storage air cooling plate 300, from one side to the other, to measure the overall insulation performance of the energy storage air cooling plate 300. In double-sided testing, the voltage applied between the first test end and the second test end is usually higher than that of single-sided testing to test the insulation strength of the entire board. Current measurement is also used to evaluate the insulation quality of the board from one side to the other. Double-sided insulation testing evaluates the insulation performance of the entire board, and the test instrument measures the resistance value from the first conductive member 600 to the third conductive member 800. After data analysis, the system will provide a comprehensive assessment of the overall insulation performance of the energy storage air cooling plate 300 to determine whether it meets all safety and performance standards.

[0096] In some embodiments, an insulation detection device for an energy storage air-cooled plate 300 further includes a cover 1000, a first telescopic member 1100, and an environmental controller (not shown in the figure). The workbench 200 includes a seventh plane 210, which is the table top mentioned above. The bottom plate 100 is connected to the workbench 200 by fasteners to install the bottom plate 100 on the seventh plane 210.

[0097] The cover body 1000 includes an accommodating space 1010 , an opening 1011 communicating with the accommodating space 1010 , a first ventilation port 1012 communicating with the accommodating space 1010 , and a second ventilation port 1013 communicating with the accommodating space 1010 .

[0098] The cover body 1000 covers the bottom plate 100, the energy storage air cooling plate 300 to be tested, the conductive foam 400, the pressure plate 500, the first conductive member 600, the second conductive member 700 and the third conductive member 800 in the accommodation space 1010, and the opening 1011 of the cover body 1000 abuts against the seventh plane 210, so that the components constituting the insulation detection device and the product to be tested are in an independent and closed environment, so as to reduce the influence of external environmental factors on the insulation detection results. It should be noted that a number of wire holes are opened on the workbench 200 for the wire harness of the test instrument to pass through, and the wire holes are filled with fillers to seal the gap between the wire harness and the wire holes.

[0099] Furthermore, in order to ensure the sealing of the opening 1011 of the cover body 1000 and the seventh plane 210 after being fitted together, a filling groove is opened at the seventh plane 210 of the workbench 200 at a position corresponding to the opening 1011 of the cover body 1000, and a sealing member is filled in the filling groove. When the opening 1011 of the cover body 1000 abuts against the seventh plane 210, the sealing member is deformed to block the gap, thereby achieving a better sealing effect.

[0100] The main shape and structure of the cover body 1000 in the specific implementation is a square block with a cavity, and the aforementioned accommodating space 1010 is constructed inside one side of the square block. The first ventilation port 1012 and the second ventilation port 1013 are both constructed on the other three sides of the cover body 1000 and are both connected to the accommodating space 1010 to provide a charging and ventilation channel for the environmental controller.

[0101] The first telescopic member 1100 includes a controlled first telescopic end 1110 , and the first telescopic end 1110 is connected to the cover body 1000 to drive the opening 1011 of the cover body 1000 to move toward or away from the bottom plate 100 .

[0102] The first telescopic member 1100 is embodied as a linear telescopic component in a specific embodiment, specifically including a telescopic cylinder, a hydraulic cylinder, and an electric push cylinder. Taking the telescopic cylinder as an example, as shown in the figure, the first telescopic end 1110 is the free end of the piston rod in the cylinder body, the telescopic direction of the first telescopic end 1110 in the first telescopic member 1100 is linear, and the telescopic direction is perpendicular to the seventh plane 210 of the workbench 200, the first telescopic end 1110 is connected to the side of the cover body 1000 away from the workbench 200, and the cover body 1000 can be moved synchronously by the telescopic movement of the first telescopic end 1110, so as to realize the opening and closing of the opening 1011 of the cover body 1000. In addition, when the first telescopic end 1110 is extended to a preset stroke, the cover body 1000 will be subjected to pressure directed to the bottom plate 100, so that the opening 1011 of the cover body 1000 is against the seventh plane 210 of the workbench 200, so as to realize the closure of the opening 1011.

[0103] The environmental controller includes an exhaust end and a ventilation end. The exhaust end is connected to the first ventilation port 1012 to draw air in the accommodating space 1010 of the cover body 1000 into the environmental controller and process the drawn air to change the temperature and humidity of the drawn air. The ventilation end is connected to the second ventilation port 1013 to re-introduce the processed air into the accommodating space 1010 of the cover body 1000 to adjust the temperature and humidity of the internal environment of the accommodating space 1010 of the cover body 1000.

[0104] The environmental controller can draw outside air into itself, and adjust the temperature and humidity of the air drawn into the interior to a preset value, and then re-exhaust the air whose temperature and humidity are adjusted to the preset value. In a specific embodiment, the environmental controller is embodied as a constant temperature and humidity all-in-one machine, which controls the temperature and humidity of the processed air through a built-in refrigeration and heating system, and a humidity adjustment component. This device usually includes a control system, a refrigeration system, a heating system, and a dehumidification or humidification system. The constant temperature and humidity all-in-one machine is equipped with a microprocessor or an intelligent control system, which can automatically monitor and adjust environmental parameters to ensure that the output air reaches the preset temperature and humidity conditions, and has an air pressure sensor to detect the ambient air pressure in the cover body 1000. The refrigeration system cools the air through components such as an evaporator, a compressor, and a condenser to reduce the air temperature to achieve the purpose of cooling. The heating system heats the air through an electric heating element or a heat exchanger to ensure that the air can reach the required temperature in a low temperature environment. The dehumidification function of the dehumidification system usually removes excess moisture by condensation, while humidification increases the air humidity by steam injection or ultrasonic atomization technology.

[0105] The specific operation process of the constant temperature and humidity machine is as follows:

[0106] Air inhalation: The air to be processed is inhaled from the first air exchange port 1012 of the cover body 1000 through the air suction end.

[0107] Temperature and humidity adjustment: The air is first cooled and dehumidified by the refrigeration system, and the condenser condenses and removes the moisture in the air. If the environment is cold, the heating system starts to heat the air to the set temperature. If needed, the humidification system may intervene to adjust the air humidity by injecting water vapor.

[0108] Air output: The processed air passes through the ventilation end and re-enters the accommodating space 1010 of the cover body 1000 through the second ventilation port 1013 .

[0109] In addition, the constant temperature and humidity all-in-one machine is connected to the first ventilation port 1012 and the second ventilation port 1013 of the cover body 1000 through a pipe or an air duct. These pipes are designed with necessary heat insulation protection and sealing measures to ensure that the air is not affected by the external environment during transmission. Furthermore, the constant temperature and humidity all-in-one machine will also be connected to sensors (such as temperature and humidity sensors) in the cover body 1000. These sensors provide real-time environmental data to the all-in-one machine, so that the all-in-one machine can adjust its operating mode according to the actual environment in the cover.

[0110] The above-mentioned constant temperature and humidity integrated machine can specifically take the Song Xing QXF series of micro constant temperature and humidity integrated machine as an example. This micro constant temperature and humidity integrated machine can actively adjust the temperature of the air to be treated, and reduce or increase the humidity of the air to be treated.

[0111] During the use of the environmental controller, when the environmental controller is turned on, the opening 1011 of the cover 1000 is closely attached to the seventh plane 210 of the workbench 200, so that the inner wall of the accommodating space 1010 in the cover 1000 and the seventh plane 210 of the workbench 200 are enclosed together to form a completely enclosed space. In this configuration, the energy storage air cooling plate 300 is completely enclosed in the enclosed space. The environmental controller is linked to the first ventilation port 1012 through its exhaust end to extract air from the enclosed space for temperature and humidity treatment. The treated air is then sent back to the enclosed space through the ventilation end and the second ventilation port 1013 to ensure that the temperature and humidity in the space are adjusted to the set target values. Conversely, when the environmental controller stops working, the opening 1011 of the cover 1000 will be separated from the seventh plane 210 of the workbench 200, so that the enclosed space can be opened, thereby allowing air to circulate naturally. This design allows the test environment conditions to be changed quickly when necessary, while also facilitating maintenance and monitoring of the equipment.

[0112] Further, in some embodiments, as shown in the figure, in order to facilitate the replacement of the energy storage air cooling plate 300 to be tested, after the energy storage air cooling plate 300 is tested, the cover body 1000 is raised to a preset height, and the pressing plate 500 is raised together with the cover body 1000, so that the energy storage air cooling plate 300 can be removed and replaced. An insulation detection device for an energy storage air cooling plate 300 also includes a second telescopic member 1200, which is arranged on the inner wall of the accommodating space 1010 of the cover body 1000 facing the bottom plate 100, and the second telescopic member 1200 includes a second telescopic end 1210, and the second telescopic end 1210 moves in a direction close to the bottom plate 100 or away from the bottom plate 100, and the second telescopic end 1210 is connected to the pressing plate 500 to drive the pressing plate 500 to move toward the conductive foam 400 or away from the conductive foam 400.

[0113] Among them, the function of the second telescopic member 1200 is to drive the pressure plate 500 to move together through the second telescopic member 1200 after the cover body 100 moves a certain distance away from the base plate 100, so that the pressure plate 500 and the conductive foam 400 move together, exposing the energy storage air cooling plate 300 in the insulation detection device for replacement. The second telescopic member 1200 is embodied as a guide column in a specific embodiment, which is a light source rod and can be further used in conjunction with a guide sleeve 1300. The guide sleeve 1300 is installed on the inner wall of the housing space 1010 of the cover body 1000 which is away from the bottom plate 100. A through groove is opened on the inner wall, and the guide sleeve 1300 is installed in the through groove. The guide column is inserted in the guide sleeve 1300. In order to prevent air leakage inside the cover body 1000, a plurality of sealing rings are installed on the inner wall periphery of the guide sleeve 1300 to block the gap between the guide column and the guide sleeve 1300. A limiting member is installed on one end of the guide column which is away from the bottom plate 100 and is located outside the cover body 1000, so that this end of the guide column cannot pass through the guide sleeve 1300. The other end of the guide column is fixedly connected to the pressure plate 500. The length of the second telescopic member 1200 is configured to ensure that when the cover body 1000 moves a preset distance away from the bottom plate 100, the limit member abuts against the end of the guide sleeve 1300 away from the bottom plate 100, so that the second telescopic member 1200 moves synchronously with the cover body 1000, thereby driving the pressure plate 500 to move upward.

[0114] During use, the operation of the pressing plate 500 mainly involves two states: a pressed state and a separated state. When the pressing plate 500 is in the pressed state, the environmental controller applies downward pressure to the pressing plate 500 through the second telescopic member 1200 to ensure that the pressing plate 500 is tightly fitted with the conductive foam 400 located below it. This tight fit ensures effective contact between the first conductive member 600 and the conductive foam 400 and the conductive foam 400 and the energy storage air cooling plate 300, thereby promoting the uniform transfer of current or voltage to the energy storage air cooling plate 300 for insulation testing. Once the insulation test of the energy storage air cooling plate 300 is completed, in order to facilitate the replacement of the plate, the pressing plate 500 needs to be transformed into a separated state. In this process, the second telescopic member 1200 acts to make the pressing plate 500 move up in the direction perpendicular to the first plane 110 of the bottom plate 100 and separate from the conductive foam 400. This movement is achieved by controlling the cover body 1000 to move upward to a preset height while utilizing the movement function of the second telescopic member 1200. The upward movement of the pressure plate 500 not only exposes the energy storage air cooling plate 300 to be tested for easy replacement, but also provides space for the placement of new test plates. The above process ensures that during the insulation test, the position and state of the pressure plate 500 can meet the test requirements, while allowing the energy storage air cooling plate 300 to be replaced quickly and efficiently, optimizing the continuity and efficiency of the test process.

[0115] Furthermore, in order to enable the pressing plate 500 to apply pressure toward the base plate 100 when the opening 1011 of the cover body 1000 abuts against the seventh plane 210 of the workbench 200, so that the pressing plate 500 and the conductive foam 400 are tightly fitted, an elastic member 900 can be installed between the inner wall of the accommodating space 1010 of the cover body 1000 on the side away from the base plate 100 and the pressing plate 500. The elastic member 900 is continuously in a compressed state, and continuously outputs an elastic force toward the base plate 100 to the pressing plate 500, thereby providing the pressing plate 500 with an elastic force directed toward the base plate 100 when the opening 1011 of the cover body 1000 abuts against the seventh plane 210.

[0116] The elastic member 900 is embodied as a spring in a specific implementation. Taking a spring as an example, it is sleeved on the outside of the second telescopic member 1200, and the spring is located between the inner wall of the accommodating space 1010 of the cover body 1000 facing away from the bottom plate 100 and the pressure plate 500, and the two ends of the spring are respectively abutted against the side of the accommodating space 1010 of the cover body 1000 facing away from the bottom plate 100 and the side of the pressure plate 500.

[0117] However, although the insulation performance of the energy storage air cooling plate 300 can be measured by the above-mentioned insulation detection device, the detection requirements of different types of energy storage air cooling plates 300 are also very different. When the accuracy requirements of the insulation standard are high, even small external influences may cause deviations in the detection results. Therefore, it is necessary to correct the preliminary detection results obtained by the insulation detection device. In order to ensure that the detection results are more accurate, the insulation detection method of the energy storage air cooling plate 300 uses a more accurate double-sided insulation detection, and corrects the results of the double-sided insulation detection. The specific double-sided insulation detection process and result correction steps are as follows:

[0118] In order to determine the impact of external factors on the test results, it is necessary to set up a temperature detection device (not shown in the figure), a humidity detection device (not shown in the figure) and a counting module (not shown in the figure) to respectively monitor and record the ambient temperature, ambient humidity and the number of times the conductive foam 400 is pressed by the pressing plate 500.

[0119] Separate the pressing plate 500 and the conductive foam 400 from the bottom plate 100, place the energy storage air cooling plate 300 to be tested on the first plane 110 of the bottom plate 100, and connect the third conductive member 800 on the bottom plate 100 to the energy storage air cooling plate 300 so that the third conductive member 800 is electrically conductive to the side of the energy storage air cooling plate 300 facing the bottom plate 100.

[0120] After the conductive foam 400 is laid on the side of the energy storage air cooling plate 300 away from the bottom plate 100, the pressing plate 500 is pressed on the side of the conductive foam 400 away from the bottom plate 100, and the first conductive component 600 is connected to the conductive foam 400, so that the first conductive component 600 is electrically connected to the side of the energy storage air cooling plate 300 away from the bottom plate 100 through the conductive foam 400.

[0121] The output terminal and the receiving terminal of the test instrument are connected to the first conductive member 600 and the third conductive member 800 respectively, and a preset voltage difference is applied between the first conductive member 600 and the third conductive member 800 .

[0122] The double-sided insulation performance of the energy storage air-cooling plate 300 is obtained according to the detection value measured between the first conductive member 600 and the third conductive member 800 .

[0123] According to the temperature detection device, the humidity detection device and the counting module, the ambient temperature, ambient humidity and the number of times the conductive foam 400 is pressed by the pressing plate are respectively obtained. According to the measured ambient temperature, ambient humidity, the number of times the conductive foam 400 is pressed by the pressing plate 500 and the conductivity of the conductive foam 400 itself, the detection value of the double-sided insulation performance of the energy storage air cooling plate 300 is corrected to obtain a corrected value.

[0124] Among them, the value of the preset voltage difference applied between the first conductive member 600 and the third conductive member 800 should be determined according to the actual situation. When the energy storage air-cooled plate 300 is used in a general energy storage system, the insulation resistance test can be set in the range of 500V to 1000V, and the withstand voltage test voltage difference can be set to 2500V to 5000V. The specific value will be further determined based on the material and industry standards.

[0125] The specific steps of obtaining the double-sided insulation performance of the energy storage air-cooling plate 300 according to the detection value measured between the first conductive member 600 and the third conductive member 800 are as follows:

[0126] The resistance value of the double-sided insulation performance test of the energy storage air-cooling plate 300 is obtained according to the preset voltage difference applied between the first conductive member 600 and the third conductive member 800 and the measured current value.

[0127] Among them, the ambient temperature, ambient humidity and the number of times the conductive foam 400 is pressed by the pressing plate 500 are obtained according to the temperature detection device, the humidity detection device and the counting module respectively, and the detection value of the double-sided insulation performance of the energy storage air-cooling plate 300 is corrected according to the measured ambient temperature, ambient humidity, the number of times the conductive foam 400 is pressed by the pressing plate 500 and the conductivity of the conductive foam 400 itself, so as to obtain the corrected value. The specific steps are as follows:

[0128] The conductivity of the conductive foam 400 is corrected according to the ambient temperature and the ambient humidity to obtain a first correction value of the conductive foam 400.

[0129] The second correction value of the conductive foam 400 is obtained according to the number of times the conductive foam 400 is pressed by the pressing plate 500 and the first correction value of the conductive foam 400 .

[0130] The correction value of the resistance value of the energy storage air cooling plate 300 obtained after the double-sided insulation performance test is obtained according to the resistance value, ambient temperature, ambient humidity and the second correction value.

[0131] Specifically, the specific steps of correcting the conductivity of the conductive foam 400 according to the ambient temperature and the ambient humidity to obtain the first correction value of the conductive foam 400 are as follows:

[0132] h 1 =C 0 k(T,H).

[0133] in:

[0134] h 1 is the first correction value. 0 is the initial conductivity of the conductive foam 400, in ohm. k(T,H) is the environmental impact factor, where T represents the ambient temperature and H represents the ambient humidity.

[0135] The calculation formula of the first correction value can accurately compensate the change of the conductive property of the conductive foam 400 in practice. The first correction value h 1 The ambient temperature and humidity are corrected through k(T,H) to provide a more accurate conductivity value. The conductivity of the conductive foam 400 will change under different environmental conditions, especially the temperature and humidity changes have a greater impact. Through this correction value, the actual conductivity can be obtained according to the current environmental conditions. Moreover, through this correction value, the conductivity measured under different temperature and humidity conditions can be unified to the same standard, so that even under non-standard environmental conditions, it is possible to accurately judge whether the performance of the conductive foam 400 meets expectations. Especially in large-scale production processes, the conductive foam 400 may be tested or used in different environments. Through the first correction value, the influence of environmental factors can be eliminated, and the reliability and comparability of the test results can be improved.

[0136] The formula of the first correction value is simple and convenient for quick calculation in practical applications. It only needs to obtain the initial conductivity C 0and environmental impact factor k(T,H), the correction value can be calculated, which is suitable for quickly adjusting the test results. Moreover, whether it is extremely high temperature, low temperature, dry or humid environmental conditions, the correction formula can provide accurate conductivity compensation. Moreover, by calculating the first correction value, it can ensure that the performance of the conductive foam 400 is stable under various environmental conditions, reducing the inconsistency of the product caused by environmental changes.

[0137]

[0138] in:

[0139] α T Represents the temperature coefficient. β H Represents the humidity coefficient. TH Represents the interaction between temperature and humidity. T , β H and δ TH Both can be obtained through nonlinear regression analysis and data-based fitting.

[0140] The calculation formula of the environmental impact factor can quantify the effect of temperature and humidity on conductivity in practice. The environmental impact factor k(T,H) is used to describe the influence of temperature T and humidity H on the conductivity of the conductive foam 400. Through the exponential form, the formula can capture the nonlinear changes of temperature and humidity on the conductivity of the conductive foam 400, especially under extreme environmental conditions. The interaction between temperature and humidity can also be further considered. The interaction term δ in the formula TH TH reflects the combined effect of temperature and humidity on the performance of the conductive foam 400. For example, under high temperature and high humidity conditions, the conductivity of the conductive foam 400 may exhibit different behaviors from those of a single temperature or humidity change, and the interaction term can help predict such changes more accurately. Especially in factories or actual use environments, the temperature and humidity conditions in different regions and time periods vary greatly, and the environmental impact factor enables the device to automatically adjust the conductivity of the conductive foam 400 to ensure consistency in the measurement results.

[0141] The calculation formula of the environmental impact factor can accurately reflect nonlinear changes. The formula adopts an exponential form, which can better simulate the nonlinear response of the conductive foam 400 under temperature and humidity changes. This is more accurate than the linear or simple weighted formula, especially under extreme conditions. T , β H and δ THThe coefficient can be obtained by fitting experimental data. For different materials, product types or usage environments, the formula can be flexibly adjusted to adapt to different scenarios. At the same time, in addition to the individual effects of temperature and humidity, the formula also takes into account the interaction between the two, making the correction of the performance of conductive foam 400 more comprehensive. The calculation formula of the environmental impact factor can further improve the accuracy of the test results. By calculating the environmental impact factor, testers can obtain consistent and reliable conductivity test results under a variety of different environmental conditions, reducing the interference of the environment on the test data.

[0142] Initial conductivity C of conductive foam 400 0 is a key parameter, which is used to modify the conductivity of the conductive foam 400 according to the ambient temperature and humidity. This initial conductivity may be obtained by the following steps:

[0143] First, prepare the conductive foam 400, select a conductive foam 400 sample of a certain specification and quality, and ensure that there is no pollutant on its surface, such as oil or moisture, which affects the conductivity.

[0144] Secondly, environmental conditions: the conductive foam 400 is placed in a test device under standard laboratory conditions.

[0145] Next, use a professional conductivity tester, usually using the four-point probe method to measure the conductivity of the conductive foam 400. This method can avoid the influence of contact resistance on the results and provide more accurate conductivity data. The tester will apply a certain current and measure the voltage to calculate the initial resistance R.

[0146] Finally, calculate the conductivity C 0 The conductivity of the conductive foam 400 is inversely proportional to its own resistance. The initial conductivity of the conductive foam 400 is calculated by the formula C0=1 / R, and the unit is Ω -1 .

[0147] During the test, it is necessary to pay attention to the environmental conditions in real time. The ambient temperature and humidity will significantly affect the measured value of the conductive foam 400. Therefore, the environmental conditions should be kept as stable as possible during the measurement, or the results should be calibrated after multiple measurements. In addition, it is necessary to ensure that the probe of the test instrument is in good contact with the conductive foam 400 to reduce the interference of the contact resistance on the measurement results. At the same time, it is also necessary to consider that different batches of conductive foam 400 may have differences in conductivity, so multiple samples are measured to obtain more representative initial conductivity values. Finally, before the test, the test equipment needs to be calibrated regularly to ensure the accuracy and reliability of the measurement results.

[0148] In order to obtain the temperature coefficient α T , humidity coefficient β H and the temperature-humidity interaction coefficient δ TH, it is necessary to design reasonable experimental steps, collect the conductivity data of conductive foam 400 under different environmental conditions, and then obtain these coefficients through mathematical modeling and regression analysis. The following are the specific steps and precautions:

[0149] Temperature coefficient α T The measurement process includes the following steps:

[0150] Select several conductive foam 400 samples of the same specifications to ensure that there is no contamination on their surface to avoid affecting the measurement results. In addition, keep the humidity of the surrounding environment constant at an intermediate value, control the ambient temperature to change gradually from low to high, and keep each temperature point long enough to allow the conductive foam 400 to reach thermal equilibrium.

[0151] Next, at each temperature point, a four-point probe method or other appropriate conductivity measurement method is used to record the conductivity value C(T) of the conductive foam 400 at each temperature.

[0152] By recording the relationship between temperature and conductivity, the nonlinear regression method is used to fit the curve of conductivity changing with temperature, and the functional form of temperature effect on conductivity k(T) is obtained, so as to determine the temperature coefficient α T .

[0153] It should be noted that during the test, it is necessary to ensure that the temperature distribution around the sample is uniform, otherwise it will affect the conductivity measurement results. After each temperature change, it is necessary to ensure that the sample has reached thermal equilibrium to avoid conductivity value fluctuations with temperature. Multiple measurements should be performed at the same temperature point to eliminate accidental errors and ensure data reliability.

[0154] Humidity coefficient β H The measurement process includes the following steps:

[0155] Keep the temperature constant at an intermediate value and adjust the humidity from low to high step by step. You can use an environmental humidity control box to accurately adjust the humidity.

[0156] At each humidity point, the conductivity C(H) of the conductive foam 400 is recorded.

[0157] Similar to the measurement of temperature coefficient, nonlinear regression analysis is performed on the relationship between humidity and conductivity to fit the function form k(H) of the influence of humidity on the conductivity of conductive foam 400, thereby determining the humidity coefficient β H .

[0158] It should be noted that the humidity must be evenly distributed throughout the test area to avoid the impact of local humidity differences on the test results. In addition, the conductive foam 400 may take some time to absorb or release moisture, so after the humidity changes, you should wait for a while for the sample to balance before measuring. At the same time, condensation should be avoided. If the humidity is too high, water vapor condensation may occur on the surface of the conductive foam 400, which will greatly affect the measurement results. Therefore, the humidity needs to be monitored to avoid this situation.

[0159] Temperature and humidity interaction coefficient δ TH The measurement process includes the following steps:

[0160] Design a matrix experiment to conduct conductivity tests under multiple temperature (such as 10°C, 25°C, 40°C) and humidity (such as 20%, 50%, 80%) combinations. For example, measure conductivity once at 10°C and 20% humidity, then measure at 10°C and 50% humidity, and so on.

[0161] Through crossover experimental design, we collected enough conductivity data under various combinations of temperature and humidity. Then, we used multiple regression analysis to fit the joint effect of temperature and humidity on conductivity and obtained the interaction coefficient δ TH .

[0162] Based on the data, establish a model for the effect of temperature and humidity on conductivity, such as where δ TH Represents the interactive effect of temperature and humidity.

[0163] It should be noted that before the experiment, it is necessary to ensure that different temperature and humidity combinations are fully covered, especially extreme conditions (high temperature and high humidity, low temperature and low humidity, etc.) to ensure that the model is applicable to a wide enough range. Multiple experiments need to be conducted under each combination of conditions to ensure stable conductivity data and reduce the impact of accidental errors. In addition, more precise environmental control equipment is required to control temperature and humidity at the same time to ensure the accuracy of the test results.

[0164] Specifically, the specific steps of obtaining the correction value of the resistance value of the energy storage air cooling plate 300 obtained after the double-sided insulation performance test according to the measured resistance value of the energy storage air cooling plate 300, the ambient temperature, the ambient humidity and the second correction value are as follows:

[0165] h 2 =h 1 ·m(N).

[0166] in:

[0167] h 2 is the second correction value. m(N) is the influence factor of the number of times used.

[0168] The second correction value h 2 Based on the first correction value, the change in the conductivity of the conductive foam 400 as the number of times used increases is further considered. During long-term use, the aging and wear of the material will affect the resistance performance of the conductive foam 400. This correction formula can more accurately reflect the electrical performance of the device after multiple uses. In addition, by considering the impact of the number of uses, it can ensure that the test results of the device after multiple uses are more authentic and reliable, avoiding inaccurate conclusions based solely on the resistance value obtained under the initial use conditions. In addition, the second correction value h 2 Compared with only considering environmental factors, adding the number of times used can more comprehensively evaluate the long-term electrical performance of the air-cooled plate. This formula can also make the test equipment more suitable for long-term, repeated use in industrial environments, ensuring that the equipment can accurately measure the resistance value at different times.

[0169]

[0170] in:

[0171] γ N represents the attenuation coefficient, which can be obtained by nonlinear regression analysis and data-based fitting.

[0172] The calculation formula of the usage times impact factor can reflect the impact of the usage times on the resistance of the conductive foam 400. The usage times impact factor m(N) is a nonlinear correction factor that changes with the usage times N, and can quantify the change in the electrical performance of the conductive foam 400 after multiple uses. Through this factor, the trend of the resistance gradually increasing with the increase in the number of times the device is used can be corrected. This formula can help predict when the conductive foam 400 needs to be maintained or replaced, thereby improving the operating efficiency of the equipment and reducing the failure rate.

[0173] In addition, since the effect of the number of uses on resistance is not linear, the logarithmic term in the formula can more accurately describe this change process, ensuring that the corrected resistance value is more realistic. The parameter γ in the formula is derived through nonlinear regression analysis, so it can be adjusted according to actual data, making the formula more adaptable in different application scenarios.

[0174] The specific steps of calculating the corrected accurate value of the resistance value of the energy storage air cooling plate 300 according to the ambient temperature, ambient humidity and the second correction value are as follows:

[0175] R corrected =R measured ·f(T)·g(H)·h 2 .

[0176] in:

[0177] Rcorrected It is a correction value of the resistance value obtained after the double-sided insulation performance test of the energy storage air cooling plate 300.

[0178] R measured It is the resistance value obtained after the double-sided insulation performance test of the energy storage air cooling plate 300.

[0179] f(T) is the temperature correction factor, which is corrected based on the ambient temperature T.

[0180] g(H) is the humidity correction factor, which is corrected based on the ambient humidity H.

[0181]

[0182] T 0 Represents the standard test temperature. T Represents the temperature sensitivity coefficient, which is determined based on experimental data.

[0183] Among them, the temperature correction factor quantifies the influence of ambient temperature through a formula, thereby correcting the error caused by temperature changes during the detection process. This is particularly important in high-precision insulation testing, especially when the equipment is used at different ambient temperatures, to ensure the accuracy of the test results. This correction method can effectively reduce the impact of temperature fluctuations on the performance of conductive materials, making the test results more reliable and consistent, especially in temperature-sensitive fields such as energy storage systems. For example, when the energy storage air-cooled plate 300 is used in different temperature environments, its insulation performance may fluctuate. By applying the temperature correction factor, these fluctuations can be taken into account to ensure that the measured resistance value is closer to the true value, thereby improving the safety and reliability of the energy storage system under different temperature conditions.

[0184] The formula for the temperature correction factor uses an exponential attenuation model, which means that the effect of temperature on material properties is nonlinear, and the properties increase or decrease exponentially as the temperature changes. The exponential model can well capture the complex effects of temperature on properties such as material or system resistance. 0 Indicates the difference between the current temperature and the standard temperature, which makes the formula flexible to apply to different temperature benchmarks, not limited to specific temperature conditions. T It can be adjusted according to the actual response data of the material or equipment to ensure that the correction factor can adapt to different material properties. For example, for some materials that are sensitive to temperature changes, a larger ∈ T Can reflect more significant temperature effects.

[0185] In summary, the temperature correction factor model in exponential form can accurately simulate the effect of temperature on material properties and adapt to various materials through parameter adjustment. It has high flexibility and accuracy and is especially suitable for insulation detection of precision equipment such as energy storage air cooling plate 300.

[0186] The temperature sensitivity coefficient reflects the response of a material or system to temperature changes. Its acquisition usually requires experimental measurements at multiple temperature points and combined with data fitting. The specific process is as follows:

[0187] Select the material or system to be tested (such as the energy storage air cooling plate 300), use a constant temperature device, such as a constant temperature box or an environmental control system, which can accurately control the temperature. Select a testing device (such as a resistance meter, conductivity tester, etc.) to measure the properties of the material (such as resistance or conductivity).

[0188] Set the experimental parameters and determine a series of temperature points T 1 ,T 2 ,…,T n , these temperature points should cover the temperature range of the actual working environment of the equipment or material, for example, from -20℃ to 80℃. Set each temperature point as the standard temperature T 0 The deviation value is used for subsequent calculation of the temperature correction factor.

[0189] At each temperature point T, the relevant performance parameters of the material (such as resistance or conductivity) are measured, and the experimental data at different temperatures are recorded, including the temperature T and the measured performance value y(T) (such as resistance value).

[0190] Using exponential models The measured temperature data and performance data are fitted by nonlinear regression analysis or least squares method. During the fitting process, the optimal temperature sensitivity coefficient ∈ T , so that the fitting curve is most consistent with the experimental data.

[0191] Finally, the fitted ∈ T Apply to other temperature points for prediction and compare with experimental data. If the error between the predicted value and the experimental value is small, it means that ∈ T Applicable to the material or system. If necessary, the accuracy can be further improved by adding experimental points or optimizing the fitting algorithm.

[0192] In practical applications, for example, when testing the insulation performance of the energy storage air cooling plate 300, the temperature sensitivity coefficient ∈ T It will be used to correct the effect of temperature fluctuation on the resistance value. T It can be used to predict and detect insulation performance under different ambient temperatures.

[0193]

[0194] H 0 Represents standard humidity. H Represents the humidity correction factor, which is determined based on experimental data.

[0195] The humidity correction factor is used to correct the test results according to the ambient humidity. Humidity changes may affect the conductivity of the material, and thus affect the measurement of insulation performance. The correction factor can quantify the impact of humidity and correct the final test results. This correction method can significantly improve the accuracy and consistency of the test results under humidity fluctuations, especially in high humidity environments, and can effectively reduce the interference of moisture on materials such as conductive foam 400. When testing the insulation of the energy storage air cooling plate 300 in a high humidity environment, since humidity will affect the electrical insulation performance, the use of the humidity correction factor can accurately adjust the resistance value to ensure the reliability of the evaluation results.

[0196] The formula of humidity correction factor adopts linear correction model, assuming that the influence of humidity on material is linear within a certain range. This form can effectively describe the influence of humidity on conductivity when humidity changes slightly, avoiding overly complex nonlinear modeling. 0 It indicates the ratio of the current humidity to the standard humidity. The introduction of this ratio allows the formula to be applied not only to a specific standard humidity, but also to adapt flexibly to different humidity environments. H It can be adjusted based on experimental data to adapt to the performance of different materials when humidity changes. For materials that are sensitive to humidity, a larger β H It reflects the significant impact of humidity changes. The linear correction formula is simple and effective, and can show good stability in scenarios where the humidity impact is not severe. By calculating the humidity correction factor, it can well simulate the impact of humidity on the conductivity and insulation of materials. Especially when the humidity is high, the insulation performance of the material usually deteriorates, and this formula can effectively compensate for this phenomenon.

[0197] Humidity correction factor β H Indicates the effect of humidity on the conductivity or insulation of the material. This coefficient is also obtained through experimental measurement and data fitting. The specific process is as follows:

[0198] Select the material or equipment to be tested (such as the energy storage air cooling plate 300), and use constant humidity equipment, such as a constant temperature and humidity chamber, to accurately control the ambient humidity. Select testing equipment (such as a resistance meter, dielectric analyzer, etc.) to measure the performance of the material (such as resistance or dielectric constant).

[0199] Determine a series of humidity points H 1 ,H 2 ,…,H n, these humidity points should cover the humidity range of the actual working environment of the equipment or material, such as from 30% RH to 90% RH. Set the standard humidity H 0 , as the reference humidity value, for subsequent humidity correction calculations.

[0200] At each humidity point H, measure the performance parameters of the material (such as resistance, capacitance or conductivity). Record the experimental data under different humidity conditions, including humidity H and measured performance value y(H).

[0201] Using linear models The humidity data and performance data are fitted by regression analysis. During the fitting process, the optimal humidity correction coefficient β is determined H , so that the fitting curve is consistent with the experimental data.

[0202] Finally, the fitted β H Apply to other humidity points for prediction and compare with experimental data. If the error between the predicted value and the experimental value is small, it means that β H It is effective for this material or device. If the error is large, you can add more experimental data points or improve the fitting model.

[0203] In practical applications, for example, the conductive foam 400 is in a high humidity environment, and its conductive properties will change with humidity. By measuring the performance of the conductive foam 400 under different humidity conditions, the humidity correction coefficient β is fitted. H , the insulation performance can be accurately calculated through the correction formula in a high humidity environment, thereby ensuring the reliability of the measurement results.
