Technical Field
[0001] This utility model relates to the field of prediction equipment technology, and in particular to a rapid prediction device for the cycle life of lithium batteries. Background Technology
[0002] With the rapid development of electric vehicles, portable electronic devices (such as smartphones, laptops, and tablets), and large-scale energy storage systems (such as grid energy storage and home energy storage solutions), lithium batteries, as energy storage devices with high efficiency and high energy density, have been widely used in many fields. Their excellent energy storage capacity and long service life make them an indispensable part of modern technology. They have not only promoted the progress of consumer electronics products, but also provided a solid foundation for the popularization of electric vehicles and the effective use of renewable energy. In addition, lithium batteries also play an important role in high-end applications such as aerospace and medical equipment, further highlighting their key position in contemporary society.
[0003] However, traditional cycle life testing methods typically require thousands of charge-discharge cycles, which is not only time-consuming (potentially months or even years), but also difficult to meet the needs of rapid decision-making in practical applications due to the high time cost. For example, in the R&D stage, long testing cycles can delay the launch of new products, and in actual use, the lack of real-time monitoring means that potential problems cannot be detected and addressed in a timely manner. These problems significantly affect the efficiency and reliability of the battery management system, limiting the further development and application of lithium battery technology.
[0004] Therefore, it is necessary to design a device for rapid prediction of lithium battery cycle life in order to solve the above-mentioned technical problems. Utility Model Content
[0005] To overcome the shortcomings of traditional cycle life testing, such as long testing time (months to years), high cost, difficulty in making quick decisions, delays in R&D testing and product launch, lack of real-time monitoring in actual use, and inability to detect and solve problems in a timely manner, which reduce system efficiency and reliability and limit the development of lithium battery technology, this utility model provides a rapid prediction device for lithium battery cycle life.
[0006] The technical implementation scheme of this utility model is as follows: a rapid prediction device for the cycle life of lithium batteries, including a support base, a detection box, a protective door, a handle, a transparent plate, a detector, a detection frame, and detection clips. Three detection boxes are installed around the support base. Each detection box has a protective door that is rotatably connected to the front top via a hinge. A handle is fixedly connected to each protective door, and a transparent plate is fixedly connected to the middle of each protective door. A detector is installed on the lower side inside each detection box, and multiple detection frames are fixedly connected to the upper side inside each detection box. Multiple detection clips are installed on each layer of the detection frame.
[0007] In addition, it is particularly preferred that the three testing chambers are respectively for the normal temperature zone, the low temperature zone, and the high temperature zone.
[0008] In addition, it is particularly preferred that the testing box is made of stainless steel.
[0009] In addition, it is particularly preferred that the device also includes a cooler, a circulation pipe and a connecting bracket. The cooler is fixedly connected to the top of the low-temperature zone detection box, and the cooler is connected to and communicates with circulation pipes at both ends. Multiple connecting brackets are fixedly connected to both sides of the inside of the low-temperature zone detection box, and each circulation pipe is installed on the corresponding connecting bracket.
[0010] In addition, it is particularly preferred that the device also includes mounting brackets and baking lamps. Multiple mounting brackets are fixedly connected to both sides of the interior of the high-temperature zone testing box, and each mounting bracket is equipped with a baking lamp.
[0011] In addition, preferably, it also includes a smoke sensor, a control module and a warning light. A smoke sensor is installed on the top of each detection box, a control module is installed on the front of the top of each detection box, and a warning light is fixedly connected to the top of each detection box. The control module is electrically connected to the smoke sensor and the warning light.
[0012] In addition, it is particularly preferred that the handle also includes a heat protection sleeve, with a heat protection sleeve fitted in the middle of each handle.
[0013] The beneficial effects of this utility model are as follows: 1. In this utility model, the operator only needs to start the detector to monitor and record the battery status parameters (such as voltage, current, temperature, etc.) in real time, which reduces the workload of manually recording data and improves the testing efficiency. In addition, the device provides three different testing environments: normal temperature zone, low temperature zone and high temperature zone, which can simulate a variety of actual use scenarios, meet different testing needs, and are suitable for a wide range of battery performance evaluations.
[0014] 2. This utility model can quickly adjust the temperature inside the testing chamber to the required low or high temperature by turning on the cooler or baking lamp, without having to wait for the ambient temperature to change naturally for a long time. For testing in the normal temperature range, no additional temperature adjustment is required, further saving time.
[0015] 3. This utility model continuously monitors the smoke concentration inside the detection chamber through a smoke sensor. Once an abnormality (such as smoke) is detected, a signal is immediately sent to the control module. After analyzing the signal, the control module triggers an alarm light to remind the operator to take appropriate measures, thus ensuring safety during the testing process.
[0016] 4. This utility model features a heat-resistant sleeve on the handle to prevent operators from being injured by contact with high-temperature components when opening the protective door, thus improving operational safety. Furthermore, operators can observe the inside of the testing chamber at any time through the transparent panel, promptly detect and address any abnormalities that may occur in the battery (such as swelling or leakage), and ensure the smooth progress of the testing process.
[0017] 5. The entire operation process of this utility model, from selecting a suitable testing box, fixing the battery to be tested, starting the corresponding heating or cooling equipment, to starting the test, observing and recording the data, and cleaning and checking after the test, is simple and clear, and easy for operators to master and execute.

Detailed Implementation
[0024] Example: A device for rapid prediction of lithium battery cycle life, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and 5As shown, the system includes a support base 1, detection boxes 2, protective doors 3, handles 4, transparent panels 5, detectors 6, detection racks 7, detection clamps 8, a cooler 9, a circulation pipe 10, a connecting frame 11, a mounting frame 12, a baking lamp 13, a smoke detector 14, a control module 15, a warning light 16, and an anti-scalding cover 17. Three detection boxes 2 are mounted around the support base 1, representing the normal temperature zone, low temperature zone, and high temperature zone, respectively. The detection boxes 2 are made of stainless steel. Each detection box 2 has a protective door 3 connected to its front upper part via a hinge. Each protective door 3 has a handle 4 installed with screws, and a transparent panel 5 is glued to the middle of each protective door 3. A detector 6 is installed on the lower inside of each detection box 2, and a multi-layer detection rack 7 is installed on the upper inside of each detection box 2 via screws. Each layer of testing rack 7 is equipped with multiple testing clips 8. The top of the low-temperature zone testing box 2 is equipped with a cooler 9 by screws. Both ends of the cooler 9 are connected to and connected with circulation pipes 10. The left and right sides of the interior of the low-temperature zone testing box 2 are connected with multiple connecting brackets 11 by welding. Each circulation pipe 10 is installed on the corresponding connecting bracket 11. The left and right sides of the interior of the high-temperature zone testing box 2 are equipped with multiple mounting brackets 12 by screws. Each mounting bracket 12 is equipped with a baking lamp 13. The top of each testing box 2 is equipped with a smoke sensor 14. The front of the top of each testing box 2 is equipped with a control module 15. The top of each testing box 2 is equipped with a warning light 16 by screws. The control module 15 is electrically connected to the smoke sensor 14 and the warning light 16. Each handle 4 is covered with a heat-resistant cover 17 in the middle.
[0025] When using this device, firstly, the operator selects the appropriate testing chamber 2 (normal temperature zone, low temperature zone, or high temperature zone) according to the testing requirements. Then, the operator opens the protective door 3 of the corresponding testing chamber 2. Each protective door 3 has a heat-resistant sleeve 17 fitted in the middle of the handle 4 to prevent the operator from being injured by contact with high-temperature components when opening the protective door 3. Next, the lithium battery to be tested is fixed in the testing clip 8 on the testing frame 7. Subsequently, the operator closes the protective door 3 and operates according to the testing requirements. For low temperature zone testing, the operator starts the cooler 9 in the low temperature zone testing chamber 2, and distributes cold air evenly into the testing chamber 2 through the circulation pipe 10 to lower the temperature to the set value. For high temperature zone testing, the operator starts the baking lamp 13 in the high temperature zone testing chamber 2 to raise the temperature inside the testing chamber 2 to the set value. For normal temperature zone testing, no additional temperature adjustment is required, and the operator proceeds directly to the next step. When starting the test, the operator starts the detector 6 to monitor the battery's status parameters (such as voltage) in real time. The system monitors the battery's internal structure (current, temperature, etc.) and records the data. During the test, the operator can observe the inside of the test chamber 2 through the transparent panel 5 to ensure the battery is operating normally and to check for any abnormalities (such as battery swelling or leakage). The smoke sensor 14 continuously monitors the smoke concentration inside the test chamber 2. Once an abnormality (such as smoke) is detected, it immediately sends a signal to the control module 15. After analyzing the signal, the control module 15 triggers the warning light 16 to issue an alarm, reminding the operator to take appropriate measures. After the test is completed, the operator turns off the corresponding heating or cooling equipment. Then, the operator opens the protective door 3 again, takes out the battery that has completed the test, and collects relevant data for analysis. Finally, the operator cleans the inside of the test chamber 2 and checks whether each component is working properly to prepare for the next test. The test chamber 2 is made of stainless steel, which has good corrosion resistance and mechanical strength, ensuring that the equipment can operate stably in various environments. The next test can be performed following the above steps.
