[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The field of battery production technology is an important part of the battery industry, which covers the entire production process of batteries from raw material processing to finished battery assembly. In this process, there are many key process links, including capacity separation and formation, and each link has extremely high requirements for the accuracy, efficiency and automation of the equipment. With the rapid development of the battery industry, higher standards have been put forward for the performance and reliability of manufacturing equipment, prompting the industry to continuously carry out technological innovation and process optimization. Battery charging and discharging detection equipment includes capacity separation equipment, formation equipment, pre-charging equipment, etc.

[0043] Battery capacity grading is a key component step in battery manufacturing and quality control. Capacity grading refers to charging and discharging tests on batteries to accurately measure the actual capacity of the battery and ensure that each battery cell in the battery pack has similar performance. The battery is first charged with a constant current until the preset charge cut-off voltage is reached. After charging is completed, the battery will be left to rest for a period of time to allow the temperature and pressure inside the battery to naturally balance. After standing, the battery is discharged with a constant current until the discharge cut-off voltage is reached. The discharge current is usually set according to the rated capacity of the battery. After the discharge is completed, the battery is left to rest again to simulate the rest state in actual use. After standing, the battery is charged with a second constant current until the charge cut-off voltage is reached. After constant current charging, the battery enters the constant voltage charging stage. At this time, the charging current will gradually decrease until the charging current drops to a very low value, indicating that the battery is close to full charge. After the constant voltage charging is completed, the battery is discharged with a final constant current to determine the actual capacity of the battery. During the entire capacity grading process, the battery voltage, current and temperature and other parameters will be monitored and recorded in real time. After the capacity separation is completed, the performance of the battery is evaluated by analyzing the data and classified according to parameters such as battery capacity and internal resistance. Based on the results of the capacity separation test, the battery will be divided into different levels for subsequent assembly and use.

[0044] The battery charge and discharge detection equipment contacts the battery and charges and discharges the battery by lifting the probe assembly. The charge and discharge equipment generally includes multiple probes to achieve the purpose of contacting multiple batteries at one time. The power module is electrically connected to the probe assembly to provide current to the probe assembly. In the prior art, the power module is usually located above the equipment, and the conventional pull-out only pulls out the power module, and the probe assembly cannot be pulled out together for maintenance. During maintenance, the power module and the probe assembly need to be repaired separately, which is inconvenient for inspection and maintenance, and the inspection efficiency is low.

[0045] Based on this, an embodiment of the present application discloses a battery charge and discharge detection device, which utilizes the width space to place the battery module on the side away from the battery support assembly, and can pull out the power module and the probe assembly, and inspect and maintain the power module and the probe assembly at the same time, thereby simplifying the maintenance process and saving maintenance time.

[0046] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0047] See also Figure 1 and Figure 2 , Figure 1 1 is a schematic structural diagram of a battery charge and discharge detection device 100 disclosed in an embodiment of the present application at a first viewing angle, Figure 2 The structure diagram of the battery charge and discharge detection device 100 disclosed in the embodiment of the present application is in the second viewing angle. The embodiment of the present application discloses a battery charge and discharge detection device 100, and the battery charge and discharge detection device 100 includes:

[0048] Base 1;

[0049] A mounting frame assembly 2, the mounting frame assembly 2 is slidably mounted on the base 1 so that the mounting frame assembly 2 can move along a first horizontal direction X;

[0050] A battery support assembly 3, the battery support assembly 3 is fixedly mounted on the base 1, and the battery support assembly 3 is used to support a battery module 33, the battery module 33 includes a battery tray 331 and batteries, and the batteries are placed in the battery tray 331;

[0051] The probe assembly 4 is fixedly mounted on the mounting frame assembly 2 and is located on a side close to the battery support assembly 3 along the second horizontal direction Y, the second horizontal direction Y is perpendicular to the first horizontal direction X, and the probe assembly 4 is used to press the positive and negative electrodes of the battery;

[0052] The power module 5 is fixedly mounted on the mounting frame assembly 2 and is located at a side away from the battery support assembly 3 along the second horizontal direction Y. The power module 5 is electrically connected to the probe assembly 4 .

[0053] In this way, the power module 5 is placed on the side away from the battery support assembly 3 by utilizing the width space, which not only reduces the height of the mechanical unit above the equipment, but also shortens the connection between the probe assembly 4 and the power module 5. The power module 5 and the probe assembly 4 are integrated on the same mounting frame assembly 2 so that the power module 5 and the probe assembly 4 can be pulled out at the same time. Since the maintenance of the power module 5 and the probe assembly 4 usually needs to be performed outside the equipment, the pull-out function of this design moves the components out of the equipment without the need for complicated disassembly steps, making maintenance operations more efficient, reducing downtime, and having less impact on production efficiency. Overhauling and maintaining the power module 5 and the probe assembly 4 at the same time simplifies the maintenance process, reduces downtime, improves maintenance and inspection efficiency, and avoids electrical safety issues that may be encountered when performing maintenance inside the equipment. Operators can perform maintenance in a safer environment outside the equipment, reducing electric shock and other safety risks.

[0054] It should be noted that the mounting frame assembly 2 and the base 1 can be slidably connected in any possible manner, and this embodiment does not limit this.

[0055] In some optional embodiments, in combination Figures 1 to 3 , Figure 3 for Figure 2Schematic diagram of the structure of the lifting module 6, the battery charge and discharge detection equipment 100 also includes a lifting module 6, the lifting module 6 is connected to the mounting frame assembly 2, the probe assembly 4 includes an upper probe assembly 411 and / or a lower probe assembly 412, the upper probe assembly 411 and / or the lower probe assembly 412 are both connected to the lifting module 6, the lifting module 6 can drive the upper probe assembly 411 and / or the lower probe assembly 412 to move in the vertical direction so that the upper probe assembly 411 and / or the lower probe assembly 412 are in contact with the positive and negative poles of the battery.

[0056] As an optional embodiment, when the positive and negative poles of the battery are on one side, the probe assembly 4 is an upper probe assembly 411 or a lower probe assembly 412, and the positive probe assembly and the negative probe assembly used to press the positive and negative poles of the battery are both located above or below the battery, and the lifting module 6 can drive the upper probe assembly 411 or the lower probe assembly 412 to move in a vertical direction to press the positive and negative poles of the battery.

[0057] As an optional embodiment, when the positive and negative poles of the battery are located on the upper and lower sides of the battery, the probe assembly 4 includes an upper probe assembly 411 and a lower probe assembly 412, and the lifting module 6 can drive the upper probe assembly 411 and the lower probe assembly 412 to approach each other in the vertical direction so that the upper probe assembly 411 and the lower probe assembly 412 are in contact with the positive and negative poles of the battery.

[0058] Through the lifting module 6, the upper and lower probe assemblies can be moved to a suitable height to ensure good contact with the positive and negative electrodes of the battery, which is very important in the charging and discharging process. Good contact can improve the charging and discharging efficiency and safety. The lifting module 6 enables the probe assembly 4 to adapt to batteries of different heights, increases the versatility and flexibility of the device, and is suitable for battery modules 33 of various specifications. At the same time, it reduces the labor intensity of manually adjusting the probe height and improves the convenience and repeatability of the operation.

[0059] In some embodiments, in combination Figures 1 to 3The lifting module 6 includes a first movable frame 61, a second movable frame 62 and a movable frame driving assembly 63. The first movable frame 61 is slidably connected to the mounting frame assembly 2, and the second movable frame 62 is slidably connected to the mounting frame assembly 2. The first movable frame 61 is located above the second movable frame 62. The probe assembly 4 includes an upper probe assembly 411 and a lower probe assembly 412. The upper probe assembly 411 is arranged on the first movable frame 61, and the lower probe assembly 412 is arranged on the second movable frame 62; the movable frame driving assembly 63 is fixedly installed on one of the first movable frame 61 and the second movable frame 62, and the output end of the movable frame driving assembly 63 is connected to the other one. When the movable frame driving assembly 63 is in an extended state, the movable frame driving assembly 63 can drive the first movable frame 61 and the second movable frame 62 to move away from each other. When the movable frame driving assembly 63 is in a contracted state, the movable frame driving assembly 63 can drive the first movable frame 61 and the second movable frame 62 to move closer to each other, so that the upper probe assembly 411 and the lower probe assembly 412 are in contact with the positive and negative poles of the battery.

[0060] In this way, the first movable frame 61 and the second movable frame 62 are driven to approach each other in the vertical direction by the movable frame driving assembly 63, and then the upper probe assembly 411 and the lower probe assembly 412 are driven to approach each other in the vertical direction to contact the positive and negative electrodes of the battery, so that the battery can be powered on to test the battery voltage, current, temperature and other parameters to divide the battery capacity. The battery support assembly 3 and the battery are both fixed, and the movable frame is only driven to move by the movable frame driving assembly 63. Under the premise of ensuring the precise contact between the positive and negative electrodes of the battery and the probe assembly 4, the operation steps of pressing the positive and negative electrodes of the battery by the upper probe assembly 411 and the lower probe assembly 412 are simplified, and it is not easy to cause damage to the battery, thereby enhancing the stability and safety of the equipment.

[0061] It should be noted that the mounting frame assembly 2 , the first movable frame 61 and the second movable frame 62 may be in any possible shape, which is not limited in this embodiment.

[0062] It should also be noted that the movable frame driving assembly 63 can be any possible driving assembly that can drive the first movable frame 61 and the second movable frame 62 to perform linear motion in the vertical direction by extension and contraction, and this embodiment does not limit this.

[0063] As an optional embodiment, the movable frame driving assembly 63 includes a cylinder 631, one of the first movable frame 61 and the second movable frame 62 is connected to the driving end 631a of the cylinder 631, and the other is connected to the non-driving end 631b of the cylinder 631, and the cylinder 631 can drive the first movable frame 61 to move vertically downward so that the upper probe assembly 411 contacts the positive pole of the battery, and the cylinder 631 can drive the second movable frame 62 to move vertically upward so that the lower probe assembly 412 contacts the negative pole of the battery.

[0064] Specifically, when the non-driving end 631b of the cylinder 631 is connected to the second movable frame 62, and the driving end 631a of the cylinder 631 is connected to the first movable frame 61, when the upper probe assembly 411 and the lower probe assembly 412 are not in contact with the positive and negative poles of the battery, the piston rod of the cylinder 631 retracts. Due to the gravity of the first movable frame 61, the first movable frame 61 will first move vertically downward until the upper probe assembly 411 contacts the positive pole of the battery. At this time, since the upper first movable frame 61 cannot continue to move downward, the second movable frame 62 will move vertically upward under the action of the retraction driving force of the cylinder 631 until the lower probe assembly 412 contacts the negative pole of the battery; the cylinder 631 When the piston rod extends out of the cylinder, due to the gravity of the second movable frame 62, the second movable frame 62 will first move vertically downward to a certain position until it can no longer move downward. At this time, the first movable frame 61 will move vertically upward under the driving force of the cylinder 631, so that the upper and lower probe assemblies 412 are separated from the positive and negative poles of the battery; when the non-driving end 631b of the cylinder 631 is connected to the first movable frame 61, and the driving end 631a of the cylinder 631 is connected to the second movable frame 62, then similarly, when the piston rod of the cylinder 631 retracts, the first movable frame 61 will first descend, and the second movable frame 62 will then rise. When the piston rod of the cylinder 631 extends out of the cylinder, the second movable frame 62 will first descend, and the first movable frame 61 will then rise.

[0065] In this way, through a cylinder 631, the upper probe assembly 411 can be first contacted with the positive electrode of the battery, and the lower probe assembly 412 can be contacted with the negative electrode of the battery, ensuring that the current of the battery always flows from the positive electrode to the negative electrode of the battery, preventing the reverse flow of current due to operational errors, which may cause abnormal chemical reactions inside the battery and increase safety hazards. As a mature linear actuator, the cylinder 631 can directly convert electrical energy into linear motion. Such a design simplifies the mechanical structure, reduces the number of transmission parts, and may reduce maintenance costs and failure rates. Moreover, the response speed of the cylinder 631 is usually fast and can provide more precise position control, which helps to improve the efficiency and accuracy of the battery charge and discharge detection device 100 in detecting and sorting batteries.

[0066] In addition, compared to some other types of driving mechanisms, such as hydraulic cylinders, the air cylinder 631 does not consume energy when not in operation, which helps to reduce the energy consumption of the device and reduces the risk of pollution. Therefore, using an air cylinder 631 to drive the upper and lower probe assemblies to move in the vertical direction can improve the performance of the battery charge and discharge detection device 100, including improving the response speed, accuracy, driving force and automation, while reducing maintenance costs and environmental pollution.

[0067] It is understandable that the movable frame and the mounting frame assembly 2 can be directly attached by magnetic force, and the movable frame driving assembly 63 can be used to realize the sliding of the movable frame on the mounting frame assembly 2, but this method is costly and will cause wear to the movable frame. Figures 1 to 3 In this embodiment, the battery charge and discharge detection device 100 also includes a third guide member 211, a first sliding member 611 and a second sliding member 621. The third guide member 211 is arranged on the mounting frame assembly 2, and the third guide member 211 is arranged in the vertical direction. The first sliding member 611 and the second sliding member 621 are both slidably connected to the third guide member 211, the first movable frame 61 is connected to the first sliding member 611, and the second movable frame 62 is connected to the second sliding member 621.

[0068] The third guide member 211 is a guide rail extending in the vertical direction, and the first sliding member 611 and the second sliding member 621 are sliders. The guide rail and the slider are slidably matched to ensure the linearity and stability of the first movable frame 61 and the second movable frame 62 in the vertical direction, reduce the offset and shaking during the movement, improve the reliability of the capacity division process, reduce the friction of the direct contact between the movable frame and the mounting frame assembly 2, reduce wear, extend the service life of the equipment, and enhance the structural stability and operational safety of the entire equipment. The vertical setting of the guide rail guides the movable frame to move along a predetermined trajectory, ensuring that the upper probe assembly 411 and the lower probe assembly 412 are accurately in contact with the positive and negative electrodes of the battery, improving the accuracy and consistency of the capacity division. In addition, the adjustment and maintenance of the guide rail and the slider are relatively easy, without the need for a complicated disassembly process, reducing the difficulty and time cost of equipment maintenance.

[0069] Optionally, the lifting module 6 also includes a positioning member 64, which is arranged on the mounting frame assembly 2, so that when the first movable frame 61 moves downward in the vertical direction until the upper probe assembly 411 contacts the positive pole of the battery, the first movable frame 61 abuts against the positioning member 64, and when the second movable frame 62 moves upward in the vertical direction until the lower probe assembly 412 contacts the negative pole of the battery, the second movable frame 62 abuts against the positioning member 64.

[0070] In this way, the setting of the positioning member 64 can ensure that the first movable frame 61 and the second movable frame 62 stop accurately when they move to a specific position, thereby ensuring the accuracy of the contact between the upper probe assembly 411 and the lower probe assembly 412 and the positive and negative electrodes of the battery. This precise positioning reduces the risk of poor contact and improves the reliability and repeatability of the capacity division process. After the upper probe assembly 411 contacts the positive electrode of the battery, the positioning member 64 can stop the first movable frame 61 from continuing to move vertically downward, and after the lower probe assembly 412 contacts the negative electrode of the battery, it stops the second movable frame 62 from continuing to move vertically upward, accurately positioning the contact points between the upper and lower probe assemblies and the positive and negative electrodes of the battery, reducing the positioning time before capacity division, improving the efficiency of battery capacity division, avoiding the hard contact between the probe assembly 4 and the battery or other parts of the device caused by excessive movement of the first movable frame 61 and the second movable frame 62, reducing damage caused by mechanical impact, protecting the battery and the upper and lower probe assemblies, and also reducing the potential safety hazards caused by improper operation or equipment failure, improving the safety of operators and equipment.

[0071] It is understandable that the positioning member 64 can be in any possible shape, which is not limited in this embodiment.

[0072] In some embodiments, in combination Figure 3 and Figure 4 , Figure 4 for Figure 3 The battery charge and discharge detection device 100 further includes a first adjusting member 613 and a second adjusting member 623. The first movable frame 61 is provided with a first extension portion 612, and the first extension portion 612 is arranged corresponding to the positioning member 64 in the vertical direction. A first adjusting hole 612a is arranged in the first extension portion 612 in the vertical direction. The first adjusting member 613 passes through the first adjusting hole 612a and can be movably connected to the first extension portion 612 to adjust the length of the first adjusting member 613 extending out of the lower surface of the first extension portion 612, so that when the upper probe assembly 411 contacts the positive electrode of the battery, the first adjusting member 613 is in contact with the positive electrode of the battery. The lower end of the node 613 abuts against the positioning member 64; a second extension portion 622 is provided on the second movable frame 62, and the second extension portion 622 is arranged corresponding to the positioning member 64 in the vertical direction. A second adjustment hole 622a is provided in the second extension portion 622 along the vertical direction. The second adjustment member 623 passes through the second adjustment hole 622a and can be movably connected to the second extension portion 622 to adjust the length of the second adjustment member 623 extending out of the upper surface of the second extension portion 622, so that when the lower probe assembly 412 contacts the negative pole of the battery, the upper end of the second adjustment member 623 abuts against the positioning member 64.

[0073] In this way, the length of the first adjusting member 613 extending out of the lower surface of the first extension 612 and the length of the second adjusting member 623 extending out of the second extension 622 can be adjusted according to the different lengths of the battery in the vertical direction, so as to control the minimum distance between the upper probe assembly 411 and the lower probe assembly 412 in the vertical direction to match the distance between the positive and negative electrodes of the battery, so that when the first adjusting member 613 abuts against the positioning member 64, the upper probe assembly 411 just contacts the positive electrode of the battery, and when the second adjusting member 623 abuts against the positioning member 64, the lower probe assembly 412 just contacts the negative electrode of the battery. The battery charge and discharge detection device 100 can adapt to batteries of different models and sizes, improve the flexibility and application range of the device, avoid mechanical damage to the battery or the probe assembly 4 caused by excessive pressure, extend the service life of the device, reduce the possibility of unnecessary mechanical stress and poor contact, improve the safety during operation, and reduce the risk of injury to the operator.

[0074] It can be understood that there are many ways to match the adjustment member and the extension part. In a first possible implementation, the two can be connected by a snap fit, thereby adjusting the length of the adjustment member extending out of the extension part, which is simple in design. In a second possible implementation, the adjustment member and the extension part are connected by threads, which make the fit tighter. This embodiment does not limit this.

[0075] As an optional implementation, combined with Figure 4 The first adjusting member 613 and the second adjusting member 623 are both screws, a first thread (not shown in the figure) is provided in the first adjusting hole 612a, the screw of the first adjusting member 613 is threadedly connected to the first adjusting hole 612a, a second thread (not shown in the figure) is provided in the second adjusting hole 622a, and the screw of the second adjusting member 623 is threadedly connected to the second adjusting hole 622a.

[0076] Through the cooperation of the screw and the threaded hole, the adjustment member can be fine-tuned in the adjustment hole, thereby fine-tuning the minimum distance between the upper probe assembly 411 and the lower probe assembly 412 in the vertical direction, improving the accuracy of the cooperation between the probe assembly 4 and the battery, and the threaded connection provides good tightness, ensuring that the adjusted state can be stably maintained and will not loosen automatically due to equipment vibration or temperature changes, thereby improving the stability and reliability of the equipment. The operator can easily fine-tune the length of the adjustment member extending out of the adjustment hole by twisting the first adjustment member 613 and the second adjustment member 623, thereby simplifying the maintenance process. Moreover, the screw is a common standard part with relatively low cost, easy to obtain and replace, and reduces the initial cost and subsequent maintenance cost of the equipment.

[0077] Specifically, combined Figures 1 to 3The battery charge and discharge detection device 100 also includes a first limit block 2111 and a second limit block 2112. The first limit block 2111 and the second limit block 2112 are both arranged on the mounting frame assembly 2. The first limit block 2111 is arranged close to the upper end of the third guide member 211, and the second limit block 2112 is arranged close to the lower end of the third guide member 211, so that when the first movable frame 61 moves vertically upward to the upper end close to the third guide member 211, the first sliding member 611 can abut against the first limit block 2111, and when the second movable frame 62 moves vertically downward to the lower end close to the second movable frame 62, the second sliding member 621 can abut against the second limit block 2112.

[0078] In this way, the setting of the first limit block 2111 and the second limit block 2112 ensures that the first movable frame 61 and the second movable frame 62 can stop accurately when reaching the limit position, which can effectively prevent the first movable frame 61 and the second movable frame 62 from overshooting due to the loss of control or improper operation of the movable frame driving component 63, avoid the movable frame from separating from the third guide member 211, protect the structural integrity of the equipment, and extend the service life of the equipment. The structure is simple, and the range of motion of the movable frame is controlled by physical limit, which reduces the requirements for accurate control of the drive system, simplifies the complexity of the control system, and reduces the control difficulty and cost.

[0079] It is understandable that the first limiting block 2111 and the second limiting block 2112 may be of any possible shape, which is not limited in this embodiment.

[0080] When the battery charge and discharge detection device 100 is in operation, Figures 1 to 3Assuming that the non-driving end 631b of the cylinder 631 is connected to the second movable frame 62, and the driving end 631a of the cylinder 631 is connected to the first movable frame 61, firstly, according to the different lengths of the battery in the vertical direction, the length of the first adjusting member 613 extending out of the lower surface of the first extension portion 612 and the length of the second adjusting member 623 extending out of the second extension portion 622 are adjusted respectively. At this time, the upper and lower probe assemblies are not in contact with the positive and negative poles of the battery, and the piston rod of the cylinder 631 retracts. Due to the gravity of the first movable frame 61, the first movable frame 61 will first move vertically downward until the upper probe assembly 411 contacts the positive pole of the battery. At this time, the lower end of the first adjusting member 613 abuts against the positioning member 64, and the first movable frame 61 cannot continue The second movable frame 62 moves downward, so at this time, under the action of the retraction driving force of the cylinder 631, the second movable frame 62 will move vertically upward until the lower probe assembly 412 contacts the negative pole of the battery, and at this time the upper end of the second adjusting member 623 abuts against the positioning member 64; when the piston rod of the cylinder 631 extends out of the cylinder barrel, due to the gravity of the second movable frame 62, the second movable frame 62 will first move vertically downward until the second sliding member 621 abuts against the second limit block 2112, and at this time the first movable frame 61 will move vertically upward under the action of the driving force of the cylinder 631 until the first sliding member 611 abuts against the first limit block 2111, and at this time the upper and lower probe assemblies both leave the positive and negative poles of the battery for the next operation.

[0081] In some optional embodiments, in combination Figure 1 and Figure 2 The battery charge and discharge detection device 100 also includes a cooling device 7 and an outer shell 8. The cooling device 7 is arranged on the outer shell 8. The cooling device 7 can cool down the gas in the battery charge and discharge detection device 100. The battery will generate a lot of heat during the charge and discharge process. Excessive temperature will affect the battery performance and even cause safety hazards. The cooling device 7 can keep the battery within the optimal operating temperature range by cooling, effectively reduce the internal temperature of the device, slow down the aging speed of the battery, extend the service life of the battery, maintain a suitable working environment, and thus ensure the stable operation of the entire system. In addition to directly protecting the battery, the cooling device 7 can also protect the probe assembly 4 and the power module 5 inside the device from high temperature damage. In addition, the cooling device 7 is connected to the outer shell 8, so that when the mounting frame assembly 2 is pulled out, only the mounting frame cooling device 7 will not move with the pulling movement, which ensures the stability of the cooling device 7, thereby ensuring the reliability and durability of the entire device.

[0082] It should be noted that the cooling device 7 can be any possible device that can cool down the hot air in the battery charge and discharge detection device 100 , and this embodiment does not limit this.

[0083] Combination Figure 1 and Figure 2The cooling device 7 includes a fan 71 and a heat exchanger 72. The heat exchanger 72 is fixedly mounted on the outer shell 8. The fan 71 is connected to the outer shell 8. The fan 71 can make the gas around the battery charge and discharge detection device 100 flow so that the gas is cooled through the heat exchanger 72. The fan 71 can promote air circulation and accelerate the heat exchange process; the heat exchanger 72 absorbs heat through medium conversion. The combination of the two can effectively improve the heat dissipation efficiency and quickly reduce the internal temperature of the equipment. Moreover, the combination of the fan 71 and the heat exchanger 72 uses air circulation to save energy consumption to a certain extent. Integrating the fan 71 and the heat exchanger 72 into the outer shell 8 not only saves space, but also facilitates integrated design, reduces additional pipeline laying, and simplifies the equipment structure.

[0084] Among them, the heat exchanger 72 may be an air-cooled heat exchanger or a water-cooled heat exchanger. In the first possible implementation, the air-cooled heat exchanger does not rely on water as a cooling medium, so it can save precious water resources and reduce the discharge of industrial wastewater, and does not require complicated water treatment and anti-corrosion measures, so the maintenance cost is low; in the second possible implementation, the water-cooled heat exchanger usually has a higher heat transfer efficiency, is suitable for high temperature and high pressure working environments, can handle higher heat loads, has a relatively simple structure, and is easy to maintain, which is not limited in this embodiment.

[0085] Combination Figure 1 and Figure 2 As an optional implementation, the cooling device 7 is located on the side of the mounting frame assembly 2 away from the battery support assembly 3 along the second horizontal direction Y. By utilizing the width space of the equipment, the limited space on both sides of the mounting frame assembly 2 is fully utilized, and the height space is further saved. Under the premise of ensuring the cooling function, the space of key operating areas such as the battery support assembly 3 and the probe assembly 4 is avoided to ensure the barrier-free operation of the main functions.

[0086] In some embodiments, the cooling device 7 is located above the power module 5, so that the gas can flow through the probe assembly 4, the battery support assembly 3 and the power module 5 after being cooled by the cooling device 7, and then flow back to the cooling device 7. Specifically, there are two cooling devices 7 and they are arranged on both sides of the mounting frame assembly 2 along the second horizontal direction Y. It is ensured that the hot air is driven by the fans 71 on both sides to enter the heat exchanger 72 for heat exchange and then blown to the upper probe assembly 411, and then passes through the battery module 33 and the lower probe assembly 412 from top to bottom, and finally passes through the power module 5 and returns to the fan 71 to be cooled again by the heat exchanger 72. Through such a cycle, the air in the battery charge and discharge detection device 100 is always kept in a flowing state to replace the heat generated by the battery charge and discharge. Such a layout helps to improve the heat dissipation efficiency, ensure that the temperature distribution inside the equipment is more uniform, quickly take away the heat inside the battery module 33, reduce the thermal damage to the battery module 33 itself, and extend the service life of the battery module 33.

[0087] See also Figure 1 and Figure 5 , Figure 5 This is a schematic diagram of the structure of the sealing component 9 disclosed in the embodiment of the present application. Optionally, the battery charge and discharge detection device 100 also includes a sealing component 9, which is arranged on both sides of the mounting frame component 2 along the first horizontal direction X. In this way, after the gas flows from the upper probe component 411 to the lower probe component 412 through the battery module 33, under the action of the sealing component 9, the gas will not flow out from the two sides of the mounting frame component 2 along the first horizontal direction X, so that the gas flows to the power module 5 after passing through the lower probe component 412, so that the flow range of the gas is concentrated as much as possible on the battery module 33 and the power module 5 that can generate heat, and the gas is guided to flow between the sealing component 9, thereby improving the cooling effect on the battery module 33 and other components inside the device, reducing the energy loss in heat exchange, making the cooling process more efficient, and helping to reduce energy consumption, achieving the effect of energy conservation and emission reduction.

[0088] Specifically, combined Figure 5 The sealing assembly 9 includes a first sealing plate 91, a second sealing plate 92 and a third sealing plate 93, and all three are arranged on the same side of the mounting frame assembly 2. The other side of the mounting frame assembly 2 is correspondingly provided with the same first sealing plate 91, the second sealing plate 92 and the third sealing plate 93. The first sealing plate 91 and the third sealing plate 93 are arranged on both sides of the power module 5. When performing pull-out inspection, since the second sealing plate 92 will interfere with the pulling movement, the second sealing plate 92 at the rear of the equipment needs to be removed, and the mounting frame assembly 2 is pulled out from the rear to inspect the probe assembly 4 and the power module 5.

[0089] Combination Figure 1 and Figure 2 As an optional embodiment, the base 1 is provided with a guide member 11 arranged along the first horizontal direction X, and the bottom of the mounting frame assembly 2 is provided with a slide rail 12, and the slide rail 12 is slidably connected to the guide member 11. In this way, the sliding connection between the guide member 11 and the slide rail 12 provides guidance for the movement of the mounting frame assembly 2, ensures the stability and accuracy of the movement in the first horizontal direction X, avoids possible deviation or shaking during the movement, and improves the overall operation accuracy of the equipment. In addition, the friction between the moving parts is reduced, which helps to extend the service life of the equipment, while reducing the cost of maintenance and replacement of parts caused by friction.

[0090] Optionally, the mounting frame assembly 2 includes a first mounting frame 21 and a second mounting frame 22, both of which are slidably connected to the base 1, and the first mounting frame 21 and the second mounting frame 22 are correspondingly arranged along the second horizontal direction Y. Correspondingly, the lifting module 6 is also two and is respectively arranged on the first mounting frame 21 and the second mounting frame 22. The probe assembly 4 includes a first probe assembly 41 and a second probe assembly 42, the first probe assembly 41 is fixedly mounted on the first mounting frame 21 along the second horizontal direction Y close to the battery support assembly 3, the second probe assembly 42 is fixedly mounted on the second mounting frame 22 along the second horizontal direction Y close to the battery support assembly 3, the upper probe assembly 411 and the lower probe assembly 412 are also two, and the first probe assembly 41 and the second probe assembly 42 respectively include a group of upper probe assembly 411 and a group of lower probe assembly 412. The power module 5 includes a first power module 51 and a second power module 52. The first power module 51 is fixedly mounted on the first mounting frame 21 at a side away from the battery support assembly 3 along the second horizontal direction Y. The second power module 52 is fixedly mounted on the second mounting frame 22 at a side away from the battery support assembly 3 along the second horizontal direction Y. The guide member 11 includes a first guide member 111 and a second guide member 112. The slide rail 12 includes a first slide rail 121 and a second slide rail 122. The first slide rail 121 is disposed at the bottom of the first mounting frame 21. The first slide rail 121 is slidably connected to the first guide member 111. The second mounting frame 22 is provided with a second slide rail 122 at the bottom. The second slide rail 122 is slidably connected to the second guide member 112.

[0091] In this way, the first mounting frame 21 and the second mounting frame 22 can be pulled out separately as needed, and the first power module 51 and the first probe assembly 41 can be inspected at the same time, or the second power module 52 and the second probe assembly 42 can be inspected at the same time. The distributed design allows for a more flexible spatial layout, which is convenient for the installation and maintenance of the equipment. The probe assembly 4 and the power module 5 on each mounting frame can work independently, reducing the mutual interference within the system and improving the accuracy of measurement and control.

[0092] Optionally, combined Figure 1 and Figure 2 The battery support assembly 3 includes a first fixing frame 31 and a second fixing frame 32, which are respectively arranged at both ends of the base 1 along the first horizontal direction X, the first fixing frame 31 is arranged between the first probe assembly 41 and the second probe assembly 42, and the battery module 33 is arranged on the first fixing frame 31 and the second fixing frame 32.

[0093] Since the mounting frame assembly 2 needs to be pulled out from the rear of the device when the battery charge and discharge detection device 100 is pulled out for maintenance, in order to avoid interference of the fixing frame with the pulling and pulling movement, the first fixing frame 31 is arranged on the base 1 relative to the rear end of the battery charge and discharge detection device 100, and the second fixing frame 32 is two and arranged on the base 1 relative to the front end of the battery charge and discharge detection device 100. The arrangement of three fixing frames provides stable support for the battery module 33. On the one hand, the first fixing frame 31 is arranged between the first probe assembly 41 and the second probe assembly 42, which effectively prevents the fixing frame from interfering with the probe assembly 4 when the probe assembly 4 is pulled out. On the other hand, the two second fixing frames 32 are arranged on the base 1 relative to the front end of the battery charge and discharge detection device 100, and are arranged corresponding to the first probe assembly 41 and the second probe assembly 42 in the first horizontal direction X, respectively, so that the first mounting frame 21 and the second mounting frame 22 will not fall off from the front of the battery charge and discharge detection device 100, thereby ensuring the functionality and stability of the overall structure of the battery charge and discharge detection device 100.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
