DETAILED DESCRIPTION
[0039] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0040] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.
[0042] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.
[0043] Testers face a heavy workload when performing battery storage tests, generating large amounts of test data that creates significant inconvenience. This situation not only easily leads to information recording errors but also creates additional workload, reducing tester accuracy and efficiency. Furthermore, for testers with limited self-awareness and collaboration, the lack of a comprehensive storage test process management system to standardize the entire process can easily lead to process confusion and internal conflicts.
[0044] The control device provided in the present application is used to control the process of the test device performing storage testing on the battery cell to be tested. It is understandable that the storage test of the battery cell to be tested mainly involves many repetitive operations such as entering the furnace and taking it out of the furnace on time to obtain voltage and internal resistance related test data. The entry, exit, storage test channel, test items, number of test cycles and total number of stages of each battery cell to be tested are all recorded by the control device of the present application, which is used to ensure the standardization and stability of the storage test of the battery cell to be tested, promote the orderly implementation of the storage allocation plan, effectively improve the test efficiency, save the test cost, and facilitate the collaboration and communication between different testers, reducing the communication cost.
[0045] In one embodiment, see the attached Figure 1 , attached Figure 1 The present invention shows one structural schematic diagram of a control device 100. In this embodiment, the control device 100 is used to control a test device 200 to perform a storage test on a battery cell 300 under test. The control device 100 includes an acquisition module 110, a first storage module 120, and a touch module 130. The acquisition module 110 is used to connect the battery cell 300 under test and the test device 200 to collect test data from the battery cell 300 under test. The first storage module 120 is connected to the acquisition module 110 and is used to store the test data. The touch module 130 is connected to the first storage module 120 and is used to receive external test instructions, so that the test device 200 can perform a storage test corresponding to the test instruction on the battery cell 300 under test and display the test data.
[0046] The test data refers to data characterizing the performance of the battery cell 300 under test during the storage test (e.g., voltage, current, temperature, DC internal resistance, cell capacity, etc.) and test records (e.g., test time, number of test phases, number of test cycles, etc.). The acquisition module 110 refers to a circuit, module, etc. capable of collecting the aforementioned test data. The first storage module 120 refers to any module capable of data storage, such as, but not limited to, a memory configured with a MySQL database.
[0047] The touch module 130 may refer to a terminal or mobile device that includes an input module (such as a mouse or touch screen) and a display screen and is capable of implementing the above-mentioned functions. The test instruction may be understood as an instruction to initiate a storage test on the battery cell to be tested. Upon receiving the instruction, the touch module 130 may display a corresponding test identifier to enable the tester to perform a storage test on the corresponding battery cell 300 to be tested, or directly convert the test instruction into an electrical signal, control the test equipment through other control modules 150 to perform a storage test on the corresponding battery cell 300 to be tested, and synchronously obtain the test data stored in the first storage module 120 to display the test data of the battery cell 300 to the tester in real time. This allows the tester to more conveniently manage data and control the test process, thereby avoiding tedious manual operations and unnecessary communication costs. This not only improves work efficiency but also saves time and energy, allowing the tester to better focus on the storage test itself.
[0048] In one embodiment, the test data includes the test time, performance parameters, test phase number and cycle number of the test cell 300, as an example. Figure 2 , attached Figure 2 The structural diagram of the acquisition module 110 in this embodiment is shown. The acquisition module 110 in this embodiment includes a timing unit 111, a detection unit 112 and a counting unit 113. The timing unit 111 is connected to the first storage module 120, and is used to connect to the test device 200 to collect the test time of the storage test performed by the test device 200 on the battery cell 300 to be tested; the detection unit 112 is connected to the first storage module 120, and is used to connect to the battery cell 300 to be tested to collect the performance parameters of the battery cell 300 to be tested; the counting unit 113 is connected to the first storage module 120, and is used to connect to the test device 200 to count the current test stage number and the current cycle number of the storage test performed by the test device 200 on the battery cell 300 to be tested.
[0049] Among them, the timing unit 111 refers to a resistor component for measuring and controlling the time interval. In this embodiment, the timing unit 111 can time a certain link of the storage test of the battery cell 300 to be tested according to a preset time interval, or can time the test duration of a certain link of the storage test of the battery cell 300 to be tested from zero. Exemplarily, the timing unit 111 includes but is not limited to a 555 timer, a low-power timer, a real-time clock (RTC), a microcontroller, etc. The performance parameters in this embodiment refer to data that characterize their own performance, such as voltage, current, temperature, DC internal resistance, battery cell capacity, etc. Correspondingly, the detection unit 112 refers to a module or circuit that can collect the above-mentioned performance parameters, such as a temperature sensor, a voltage sensor or a specific test equipment. The counting unit 113 refers to an electronic component that can realize the counting function, such as a counter or a counting component, but is not limited to this.
[0050] In this embodiment, the test data of the battery cell 300 to be tested during the storage test is obtained in real time through the timing unit 111, the detection unit 112 and the counting unit 113, so that the tester can more efficiently understand the storage test progress of the battery cell 300 to be tested and the performance of the battery cell 300 to be tested, which is conducive to improving the monitoring efficiency of the storage test of the battery cell 300 to be tested.
[0051] In one embodiment, the performance parameters including resistance, voltage and temperature are used as an example for explanation. Figure 3 , attached Figure 3 The schematic diagram of the structure of the detection unit 112 in this embodiment is shown. The detection unit 112 in this embodiment includes a first detection circuit 1121 and a second detection circuit 1122. The first detection circuit 1121 is connected to the first storage module 120 and is used to connect to the battery cell 300 to detect the voltage and resistance of the battery cell 300. The second detection circuit 1122 is arranged near the battery cell 300 to be tested and connected to the first storage module 120, and is used to detect the temperature of the battery cell 300 to be tested. The first detection circuit 1121 can be any circuit including electronic components capable of detecting voltage and resistance. The second detection circuit 1122 can be a circuit provided with a temperature sensor.
[0052] In this embodiment, the performance parameters of the battery cell 300 to be tested can be acquired in real time through the first detection circuit 1121 and the gain detection circuit, so as to archive and analyze the test data of the battery cell 300 to be tested.
[0053] The touch module 130 is also used to receive external input allocation instructions. The allocation instructions are used to represent the corresponding relationship between the battery cell 300 to be tested and the test conditions. Specifically, the allocation instructions include the channel allocation of a battery cell 300 to be tested in the test device 200, the total number of cycles to be tested, the total number of stages, and the test items. For example, the cycle number is in days and is connected by a minus sign (-). For example, 1-7-15 describes a cycle that takes 1 day to produce the first stage, 7 days to produce the second stage, and 15 days to produce the third stage, for a total of 3 stages.
[0054] In one embodiment, see the attached Figure 4 , attached Figure 4 The second structural diagram of the control device 100 in this embodiment is shown. The control device 100 in this embodiment also includes a second storage module 140, which is connected to the touch module 130. The second storage module 140 is used to store the correspondence between the battery cell 300 to be tested and the test conditions corresponding to the arrangement instruction.
[0055] In this embodiment, according to the actual test needs of the battery cell 300 to be tested, the arrangement instructions are input through the touch module 130 to flexibly set the test conditions of the battery cell 300 to be tested. This allows the tester or the external control module 150 to perform operations such as putting the corresponding battery cell 300 to be tested into or out of the furnace according to the above-mentioned correspondence. If the total number of stages is not 0, it is necessary to repeat the relevant processes such as taking the battery cell out of or into the furnace. After the battery cell is taken out of the furnace according to the specified time, the test data of the battery cell is obtained through the acquisition module 110, and the test data of the battery cell is recorded through the first storage module 120. After the test is completed, the battery cell to be tested can be removed to complete the storage test.
[0056] It is understandable that in this embodiment, only the test conditions of the newly added battery cell 300 to be tested are used as an example for illustration. In other embodiments, the user can also input a delete command through the touch module 130 to delete the correspondence between one or more battery cells 300 to be tested and the test conditions stored in the second storage module 140. This process can also be displayed in the touch module 130. That is, the control device 100 in this embodiment has an excellent interface interaction effect, which enables the user to easily configure the stored test conditions. At the same time, according to the test items, the user can select the corresponding correspondence between the battery cell 300 to be tested and the test conditions in the second storage module 140 and display it.
[0057] Furthermore, in one embodiment, the second storage module is also used to store the cell barcode of the cell to be tested; the cell barcode corresponds to the cell to be tested, and the correspondence between the cell to be tested and the test conditions is represented by the correspondence between the cell barcode and the test conditions.
[0058] In addition, the battery cell to be tested may be locked by information such as the order number and the box number, and is not limited to the battery cell barcode in this embodiment.
[0059] In this embodiment, the second storage module stores the cell barcodes of the battery cells to be tested. The cell barcodes of the battery cells to be tested are inconsistent, that is, the cell barcodes correspond one-to-one to the battery cells to be tested. Therefore, the corresponding battery cell to be tested can be locked through the cell barcode, and the correspondence between the battery cell to be tested and the test conditions can be determined based on the correspondence between the cell barcode and the test conditions.
[0060] In one embodiment, the test conditions include at least one of the total number of test phases, the number of test cycles, the test items, and the test channel number of the battery cell to be tested in the test device.
[0061] Each battery cell to be tested is located in a different test channel in the test device, so each test channel can be numbered to distinguish different test channels.
[0062] It can be understood that the test conditions for each battery cell to be tested are different. Configuring the corresponding total number of test stages, test cycles and test items for each battery cell to be tested and at least one of the test channels of the battery cell to be tested in the test device will help monitor the storage test progress of each battery cell to be tested.
[0063] In one embodiment, see the attached Figure 5 , attached Figure 5 The third structural schematic diagram of the control device 100 in this embodiment is shown. The control device 100 in this embodiment also includes a control module 150. The control module 150 is connected to the touch module 130, the first storage module 120, and the second storage module 140. The control module 150 is used to connect to the test device 200 and receive the electrical signal corresponding to the test instruction transmitted by the touch module 130 to control the test device 200 to perform storage testing on the battery cell 300 to be tested.
[0064] The control module 150 can be a microcomputer capable of realizing data and signal transmission, such as a single-chip microcomputer. For example, after the user performs batch test condition configuration operations on multiple battery cells 300 to be tested, the control module 150 will perform furnace entry and exit operations on the corresponding battery cells based on the corresponding relationship stored in the second storage module 140 to perform storage tests on the battery cells 300 to be tested. In addition, the control module 150 can control the test device 200 in real time according to the test data stored in the first storage module 120. For example, after the test time meets the conditions, the test device 200 is controlled to continue to perform storage tests on the battery cells 300 to be tested. In this embodiment, the control module 150 can realize intelligent control and monitoring of storage tests on the battery cells 300 to be tested, avoiding the uncertainty that may be caused by human operation and ensuring the accuracy and reliability of the operation.
[0065] In one embodiment, see the attached Figure 6 , attached Figure 6 FIG4 shows a fourth structural diagram of the control device 100 in this embodiment. The control device 100 in this embodiment further includes a power supply module 160. The power supply module 160 is configured to connect to the test device 200 via the control module 150 and to supply power to the test device 200, so that the test device 200 performs the storage test on the battery cell 300 under the power of the power supply module 160. The control device 100 in this embodiment further includes a power supply module 160 for providing the test device 200 with the necessary electrical energy to perform the storage test, thereby further improving the functionality of the control device 100.
[0066] In one embodiment, the touch module is also used to receive an external stop command; the control module is also connected to the power supply module, and is used to connect each test channel in the test device. When the stop command transmitted by the touch module is received, the connection between the power supply module and the test channel corresponding to the stop command is disconnected, so that the test channel in the test device stops performing storage testing on the battery cell to be tested.
[0067] It can be understood that each battery cell to be tested is subjected to a storage test in a separate test channel in the test equipment. In order to achieve independent control of each battery cell to be tested, the control module is respectively connected to the power supply module and the power supply end of each test channel to form a power supply circuit. When the stop command transmitted by the touch module is received, the control module controls the connection between the power supply module and the power supply end of the corresponding test channel to be disconnected, so that the storage test of the battery cell to be tested located in the test channel is stopped, thereby achieving independent control of the storage test of each battery cell to be tested.
[0068] In one embodiment, the control module can also control the test device to jump out of the storage test cycle. For example, in an actual project, it is necessary to repeatedly put the battery cell under test into and out of the furnace, for example, put it into the furnace for 5 consecutive days, then put it into the furnace for 5 consecutive days, and so on. In order to simplify the operation, these repeated days can be defined as cycle days and expressed in a structured manner. For example, a 5-day cycle setting can be simplified to [5]. When the storage test process encounters a situation where the current cycle needs to be interrupted, the user only needs to input the break command through the touch module, and the acquisition module will automatically add 1 to the current stage number, and then the control module will continue to control the test device to perform the next stage test on the battery cell under test. This not only improves the efficiency of the test, but also provides users with a more flexible operating experience.
[0069] In one embodiment, see the attached Figure 7 , attached Figure 7The schematic diagram of the structure of the test system 10 in this embodiment is shown. The test system 10 in this embodiment includes a test device 200 and a control device 100 in any of the above embodiments. The control device 100 is connected to the test device 200 and the battery cell 300 to be tested, and is used to control the test device 200 to perform a storage test on the battery cell 300 to be tested.
[0070] It can be understood that the test system 10 in this embodiment includes the control device 100 in any of the above embodiments. When the control device 100 has further beneficial effects compared to the prior art, the test system 10 also has further beneficial effects accordingly.
[0071] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0072] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
