Technical Field
[0001] This application relates to the field of battery testing technology, and in particular to a battery testing method, system, smart terminal, and storage medium. Background Technology
[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and a non-aqueous electrolyte solution. They are widely used in mobile communication equipment and transportation power sources due to their small size, long life and pollution-free characteristics.
[0003] In related technologies, as lithium batteries have gradually been developed into multiple industries, in order to ensure the safety of lithium batteries during use, after the lithium battery is manufactured, it is necessary to conduct multiple tests on the lithium battery, such as the parameters of the lithium battery current and voltage. After the technicians connect the lithium battery to the testing equipment, they adjust the range of the testing equipment according to the rated parameters on the lithium battery, so as to test the parameters of the lithium battery with the highest accuracy.
[0004] Regarding the aforementioned technologies, when testing the voltage and current of lithium batteries, technicians need to adjust the range of the testing equipment according to the rated parameters of the lithium battery. When the rated parameters of the lithium battery are different, technicians need to continuously adjust the testing equipment before the lithium battery can be tested, resulting in low testing efficiency and room for improvement. Summary of the Invention
[0005] To improve the testing efficiency of lithium batteries, this application provides a battery testing method, system, smart terminal, and storage medium.
[0006] Firstly, this application provides a battery testing method, employing the following technical solution: A battery testing method, comprising: Obtain the battery connection trigger information of the battery under test; Obtain test item information based on battery connection trigger information; According to the test item information, the preset test equipment is controlled to test the battery under test with the preset maximum range information, and the battery test result information is obtained. Determine whether the battery test results meet the requirements of the maximum range information; If the conditions are met, the battery test result information is determined as the final test result information; If the battery does not meet the requirements, the testing equipment will be controlled to retest the battery based on the battery test results.
[0007] By adopting the above technical solution, when the battery under test is connected to the testing equipment, i.e., when the battery connection trigger information is detected, the battery's test item information is detected. Based on the test item information, the testing equipment is controlled to test the battery under test at its maximum range, thereby detecting the battery test result information. If the test result is within the range of the maximum range information, the battery test result information is determined as the final test result information; otherwise, the testing equipment is controlled to adjust the range based on the battery test result information and test the battery under test again. This saves the step of personnel constantly adjusting the range of the testing equipment by observing the battery's rated parameters, thus improving the testing efficiency of lithium batteries.
[0008] Optionally, methods for controlling the testing equipment to retest the battery under test based on the battery test results include: The final range information is determined by analyzing the battery test results. The control test equipment is adjusted to the final range information to test the battery under test and obtain the battery adjustment test result information; The range error information is determined by analyzing the final range information and the maximum range information. The battery adjustment test results and battery test results are analyzed to determine the test result error information; Determine whether the error information of the test results meets the requirements of the range error information; If the conditions are met, the final test result information will be determined based on the battery adjustment test results. If it does not meet the requirements, the testing equipment is controlled to adjust the range to obtain the final test result information.
[0009] By adopting the above technical solution, the highest precision final range information is determined based on the battery test results, and the test equipment is controlled to adjust to the final range information to perform testing on the battery under test. This yields battery adjustment test results under a high precision range. The range error information between the ranges is determined based on the final range information and the maximum range information. The test result error information of the battery test under the two ranges is determined based on the battery adjustment test results and the battery test results. If the test result error information does not exceed the range error information, the final test result information can be determined based on the battery adjustment test results. If it does exceed the range error information, the test equipment is controlled to readjust the range to obtain the final test result information. This verifies whether the highest precision range or the maximum range is normal for the battery test results, thereby improving the accuracy of the battery test results.
[0010] Optionally, methods for controlling the testing equipment to adjust the measurement range to obtain the final test result information include: When the test result error information does not meet the requirements of the range error information, the maximum range information and the final range information are analyzed to determine whether there is intermediate range information. If not, identify the fault information of the test equipment and display a prompt; If present, the control test equipment is sequentially adjusted to the intermediate range information, and the intermediate test result information of the battery is obtained; The final test results are determined by analyzing the intermediate battery test results and the battery adjustment test results.
[0011] By adopting the above technical solution, when the test result error information exceeds the range error information, it is determined whether there is intermediate range information between the maximum range information and the final range information. If not, it indicates that the test equipment has malfunctioned when performing the test at the maximum range or the final range, so the test equipment malfunction information is identified and prompted. If it exists, the test equipment is controlled to adjust to the intermediate range information to obtain the intermediate test result information of the battery. Based on the intermediate test result information and the battery adjustment test result information, the final test result information is determined. Thus, when there may be problems with the maximum range and the final range, the intermediate range is used to test the battery, thereby improving the accuracy of the battery test results.
[0012] Optionally, methods for determining the final test results by analyzing intermediate battery test results and battery adjustment test results include: The intermediate test results and battery adjustment test results are analyzed to determine the error information of the intermediate test results. The intermediate range error information is determined by analyzing the intermediate range information and the final range information. Determine whether the error information of the intermediate test results meets the requirements of the intermediate range error information; If it does not meet the requirements, the control equipment will be adjusted to the next intermediate range information, and the intermediate test result information of the battery will be obtained. If the conditions are met, the battery intermediate test result information is determined to be valid intermediate test result information; Obtain the trigger information for the completion of the intermediate range test; Based on the intermediate range test completion trigger information, the final test result information is determined by analyzing the valid intermediate test result information and the battery adjustment test result information.
[0013] By adopting the above technical solution, the intermediate test result error information between the test results tested at the intermediate range and the final range is determined based on the battery intermediate test result information and the battery adjustment test result information. The intermediate range error information between the intermediate range and the final range is also determined. If the intermediate test result error information does not exceed the intermediate range error information, the final range is determined to be fault-free. Therefore, the battery intermediate test result information is determined to be valid intermediate test result information. After all intermediate ranges have been tested, that is, when the intermediate range test completion trigger information is detected, the final test result information is determined based on the valid intermediate test result information and the battery adjustment test result information, thereby improving the accuracy of the battery test results.
[0014] Optionally, methods for determining the final test result information based on battery adjustment test result information include: Determine whether the battery adjustment test results meet the requirements of the preset range endpoint values; If it does not meet the requirements, the battery adjustment test result information will be determined as the final test result information; If the conditions are met, the adjacent range information will be determined by analyzing the battery adjustment test results and the final range information. The control and testing equipment is adjusted to the adjacent range information to test the battery under test, and the test result information of the adjacent range is obtained; The final test results are determined by analyzing the results of adjacent range tests and battery adjustment tests.
[0015] By adopting the above technical solution, when the battery adjustment test result information is the endpoint value of the range, the adjacent range information that is close to the battery adjustment test result information and adjacent to the final range information is determined. The test equipment is then controlled to detect the battery under test with the adjacent range information, thereby obtaining the adjacent range test result information. The final test result information is then determined based on the adjacent range test result information and the battery adjustment test result information, thereby improving the accuracy of the battery test results.
[0016] Optionally, before obtaining the battery test results, a verification method for the battery under test is also included, specifically including: The battery power information and full charge information of the battery under test are obtained based on the battery connection trigger information. Determine whether the battery power information meets the requirements for a fully charged battery. If the conditions are met, the testing equipment will be controlled to test the battery under test. If the conditions are not met, the battery under test will be verified based on the battery power information and the battery full charge information.
[0017] By adopting the above technical solution, the battery power information and full charge information of the battery under test are detected. When the battery power information is equal to the full charge information, it indicates that the power will not affect the battery test. Therefore, the test equipment is controlled to detect the battery under test. When the battery power information is not equal to the full charge information, the battery under test is verified based on the battery power information and the full charge information, thereby improving the accuracy of battery testing.
[0018] Optionally, methods for verifying the battery under test based on battery power information and full battery power information include: Calculate the difference between the battery full charge information and the battery charge information, and define the calculated difference as the battery low charge information; Determine whether the battery low power information meets the preset requirements for direct charging power information; If it does not meet the requirements, a preset disconnection charging message will be output to prompt the user to disconnect the charging. If the conditions are met, the charging power information of the battery under test is obtained. Control the preset charging device to charge the battery under test with the charging power information, and obtain the charging device's power level remains unchanged trigger information; The charging device stops charging based on the trigger information that the battery level remains unchanged.
[0019] By adopting the above technical solution, the difference between the battery full charge information and the battery charge information is calculated to obtain the battery low charge information. When the battery low charge information exceeds the direct charging capacity information, a disconnection charging information is output to prompt the user to disconnect and start charging. When it does not exceed the limit, the charging power information of the battery under test is obtained, thereby controlling the charging device to charge the battery under test according to the charging power information. When the charge of the charging device remains unchanged, that is, when the unchanged charge trigger information is detected, the charging device is controlled to stop charging, thereby improving the convenience of the battery under test verification.
[0020] Secondly, this application provides a battery testing system, which adopts the following technical solution: A battery testing system, comprising: The acquisition module is used to acquire battery connection trigger information, test item information, and battery test result information. A memory for storing a program for a battery testing method as described in any of the preceding claims; The processor and the program in the memory can be loaded and executed by the processor to implement a battery testing method as described in any of the above.
[0021] By adopting the above technical solution, a series of data related to battery testing are acquired through the acquisition module. When battery testing is required, the control processor loads and executes a battery testing method program stored in the memory, thereby completing the battery test. This saves personnel from constantly adjusting the range of the testing equipment, thus improving the efficiency of battery testing.
[0022] Thirdly, this application provides a smart terminal, which adopts the following technical solution: A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed as described in any of the preceding claims.
[0023] By adopting the above technical solution, the processor loads and executes a computer program for a battery testing method stored in the memory through the operation of a smart terminal by personnel, thereby completing the battery test and saving the step of constantly adjusting the range of the testing equipment, thus improving the efficiency of battery testing.
[0024] Fourthly, this application provides a computer storage medium capable of storing corresponding programs, which facilitates improving the testing efficiency of lithium batteries, and adopts the following technical solution: A computer-readable storage medium storing a computer program that can be loaded by a processor and executed by any of the above-described battery testing methods.
[0025] By adopting the above technical solution, a computer program for a battery testing method is stored in a computer-readable storage medium. When the battery needs to be tested, the control processor loads and executes the computer program stored in the storage medium, thereby completing the battery test. This saves personnel from constantly adjusting the range of the testing equipment, thus improving the efficiency of battery testing.
[0026] In summary, this application includes at least one of the following beneficial technical effects: By detecting the battery connection trigger information when the battery under test is connected to the testing equipment, the battery's test item information is detected. The testing equipment is then controlled to test the battery under test at the maximum range based on the test item information, thereby detecting the battery test result information. If the test result is within the range of the maximum range information, the battery test result information is determined as the final test result information. Otherwise, the testing equipment is controlled to adjust the range of the test equipment based on the battery test result information and test the battery under test again. This saves the step of personnel looking at the battery's rated parameters to continuously adjust the range of the testing equipment, thereby improving the testing efficiency of lithium batteries. By determining the highest precision final range information based on battery test results, and controlling the test equipment to adjust to the final range information to perform testing on the battery under test, the battery adjustment test result information under high precision range is obtained. The range error information between the ranges is determined based on the final range information and the maximum range information. The test result error information of the battery test under the two ranges is determined based on the battery adjustment test result information and the battery test result information. If the test result error information does not exceed the range error information, the final test result information can be determined based on the battery adjustment test result information. If it exceeds the range error information, the test equipment is controlled to adjust the range again to obtain the final test result information, thereby verifying whether the highest precision range or the maximum range is normal for the battery test results, and thus improving the accuracy of the battery test results. When the test result error exceeds the range error, it is determined whether there is an intermediate range between the maximum range and the final range. If not, it indicates that the test equipment malfunctioned when performing the test at the maximum or final range, and the test equipment malfunction information is identified and displayed. If it does exist, the test equipment is controlled to adjust to the intermediate range to obtain the intermediate test result information of the battery. Based on the intermediate test result information and the battery adjustment test result information, the final test result information is determined. In cases where there may be problems with the maximum and final ranges, the intermediate range is used to test the battery, thereby improving the accuracy of the battery test results.

[0034] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.
[0035] This application discloses a method for automatically switching the range of a testing device to test a battery. After the positive and negative terminals of the battery are connected to the testing device, the processing system obtains battery connection trigger information, thereby controlling the testing device to obtain test item information for testing the battery. The processing system controls the testing device to test the battery at the maximum range information according to the test item information, thereby obtaining battery test result information under the maximum range accuracy information. When the battery test result information is within the range of the maximum range information, the battery test result information can be determined as the final test result information. When the battery test result information is less than the range of the maximum range information, the processing system controls the testing device to switch to the highest accuracy range corresponding to the battery test result information and then test the battery. This reduces the steps required for personnel to adjust the range of the testing device according to the rated parameters of the battery, thereby improving the battery testing efficiency.
[0036] Reference Figure 1 This application discloses a battery testing method, including the following steps: Step S100: Obtain the battery connection trigger information of the battery under test.
[0037] In this context, "battery under test" refers to the battery that needs to be tested. This application uses a lithium battery as an example; the specific parameters of the lithium battery can be set by those skilled in the art based on actual conditions, and will not be elaborated here. "Battery connection trigger information" refers to the trigger data after the positive and negative terminals of the battery under test are connected to the testing equipment. In one embodiment, after the battery under test is connected to the testing equipment, the testing equipment detects the battery's voltage response and outputs the battery connection trigger information. In another embodiment, after the user connects the battery under test to the testing equipment, they input the battery connection trigger information into the processing system.
[0038] Step S101: Obtain test item information based on battery connection trigger information.
[0039] Among them, the test item information refers to the test items performed on the battery under test, including voltage and current, which are entered by personnel into the processing system after the battery under test is connected to the test equipment.
[0040] Step S102: Control the preset test equipment to test the battery under test with the preset maximum range information according to the test item information, and obtain the battery test result information.
[0041] The testing equipment refers to the device used to test the voltage and current of the battery under test. The specific parameters of the testing equipment are set by those skilled in the art based on actual conditions, such as voltage and current ranges. Maximum range information refers to the maximum range at which the testing equipment can test voltage or current; the specific value is set by those skilled in the art based on actual conditions. Battery test result information refers to the results of the testing equipment testing the battery under test at the range corresponding to the maximum range information, including current and voltage, obtained by the testing equipment.
[0042] After determining the test item information, the test equipment is controlled to test the battery under test with the range corresponding to the maximum range information and the test item information corresponding to the test item information, so as to obtain the battery test result information and provide data support for subsequent determination of whether to change the range.
[0043] Step S103: Determine whether the battery test result information meets the requirements of the maximum range information.
[0044] The requirement for maximum range information refers to the measurement range corresponding to the maximum range information. By determining whether the test result corresponding to the battery test result information is within the range corresponding to the maximum range information, it is determined whether the accuracy of the test equipment in testing the battery under test with the maximum range information meets the test requirements.
[0045] Step S1031: If the conditions are met, the battery test result information is determined as the final test result information.
[0046] If the test result corresponding to the battery test result information is within the range corresponding to the maximum range information, then it is determined that the test equipment has high enough accuracy to test the battery under test with the maximum range information and meets the test requirements. Therefore, the battery test result information is determined as the final test result information.
[0047] The final test result information refers to the test result output by the test equipment that meets the test requirements. In this step, the processing system defines the battery test result information as the final test result information based on the comparison results of the battery test result information within the range corresponding to the maximum range information.
[0048] Step S1032: If it does not meet the requirements, control the testing equipment to retest the battery under test based on the battery test result information.
[0049] If the test result corresponding to the battery test result information is less than the range corresponding to the maximum range information, it is determined that the accuracy of the test equipment using the maximum range information is low, and the test result does not meet the accuracy requirements. Therefore, the test equipment is controlled to change the range based on the battery test result information, thereby retesting the battery and improving the accuracy of the test results. Specific test methods are described in [reference needed]. Figure 2 The steps.
[0050] Reference Figure 2 The method for controlling the testing equipment to retest the battery under test based on the battery test results includes the following steps: Step S200: Analyze the battery test results to determine the final range information.
[0051] The final range information refers to the range with the highest accuracy when testing the battery test results. It is obtained by the processing system after analyzing the results corresponding to the battery test results. For example, if the test result corresponding to the battery test results is 150 mA, and the range of the test equipment is divided into 0 to 100 mA, 0 to 200 mA, 0 to 300 mA, 0 to 400 mA, and 0 to 500 mA, then the range of 0 to 200 mA is determined to be the range with the highest accuracy when testing the battery under test. Therefore, the final range information is 0 to 200 mA.
[0052] Step S201: Control the test equipment to adjust to the final range information to test the battery under test, and obtain the battery adjustment test result information.
[0053] After determining the final range information, the processing system adjusts the range of the test equipment according to the range information to retest the battery under test, thereby obtaining the battery adjustment test result information and providing data support for the subsequent determination of the final test result information.
[0054] Battery adjustment test result information refers to the test result after the test equipment adjusts the range with the final range information and then tests the battery under test again.
[0055] Step S202: Analyze the final range information and the maximum range information to determine the range error information.
[0056] Among them, the range error information refers to the maximum error value between the test results when testing the same battery with two ranges. It is obtained by the processing system after analyzing the final range information and the maximum range information. The analysis method is as follows: the test error value between different ranges is a fixed value, which is obtained by technicians using different ranges to test the same battery and then comparing the results. The error is then stored in the database after being mapped to the range. Two ranges are input, and the error value is matched and output. For example, if the ranges of 0 to 200 mA and 0 to 500 mA are input, the error between the two ranges will be output.
[0057] Step S203: Analyze the battery adjustment test results and battery test results to determine the test result error information.
[0058] Among them, the test result error information refers to the error value between the test results of the test equipment using the maximum range information and the final range information of the battery under test. It is obtained by the processing system calling the battery adjustment test result information and the battery test result information, taking the absolute value. For example, if the battery adjustment test result information is 152 mA and the battery test result information is 150 mA, then the test result error information is 2 mA.
[0059] Step S204: Determine whether the error information of the test result meets the requirements of the range error information.
[0060] The requirement for range error information is that it should not exceed the error value corresponding to the range error information. By determining whether the error value corresponding to the test result error information is not greater than the error value corresponding to the range error information, it can be determined that the test equipment is in normal condition when testing the battery with the maximum range information and the final range information.
[0061] Step S2041: If the conditions are met, the final test result information is determined based on the battery adjustment test result information.
[0062] If the error value corresponding to the test result error information is not greater than the error value corresponding to the range error information, it indicates that the test equipment is in a normal state when testing the battery with the maximum range information and the final range information. Therefore, the battery adjustment test result information detected by the test equipment with the final range information has high accuracy. Thus, the final test result information is determined based on the battery adjustment test result information. The specific determination method is as follows: Figure 5 The steps.
[0063] The final test result information in this step refers to the high-precision result of the battery test determined by the processing system based on the battery adjustment test result information. The specific determination method is detailed in [reference needed]. Figure 5 The steps.
[0064] Step S2042: If it does not meet the requirements, control the testing equipment to adjust the range to obtain the final test result information.
[0065] If the error value corresponding to the test result error information is greater than the error value corresponding to the range error information, it indicates that the test equipment may be in a faulty state when testing the battery with the maximum range information and the final range information. Therefore, the test equipment is controlled to adjust the range and test the battery under test again to obtain the final test result information.
[0066] The final test result information in this step refers to the high-precision result obtained from battery testing after the test equipment's range has been readjusted. Refer to [link / reference] for specific methods on how to obtain the result. Figure 3 The steps.
[0067] Reference Figure 3 A method for controlling the testing equipment to adjust the measurement range to obtain the final test result information includes the following steps: Step S300: When the test result error information does not meet the requirements of the range error information, analyze the maximum range information and the final range information to determine whether there is intermediate range information.
[0068] When the error corresponding to the test result error information exceeds the error corresponding to the range error information, it indicates that the test equipment may malfunction when testing with the maximum range information and the final range information. Therefore, it is necessary to determine whether there is intermediate range information based on the maximum range information and the final range information, so as to provide data support for subsequent control of the test equipment to adjust the range.
[0069] Intermediate range information refers to the range between the maximum range information and the final range information. It is obtained by the processing system after analyzing the maximum range information and the final range information. The analysis method is as follows: if the maximum range information is 0 to 500 mA and the final range information is 0 to 200 mA, then intermediate range information is determined to exist. If the final range information is 0 to 400 mA, then intermediate range information is determined not to exist.
[0070] Step S301: If it does not exist, determine the fault information of the test equipment and display a prompt.
[0071] If there is no intermediate range information between the maximum range information and the final range information, then the final range information and the maximum range information are determined to be two adjacent ranges. Therefore, since there is no intermediate range information, if the test results obtained by the test equipment using the final range information and the maximum range information have a large error, it can only be determined that the test equipment is faulty. Thus, a test equipment fault message is generated, and personnel are alerted. The test equipment fault message refers to the prompt message indicating that the test equipment has malfunctioned. The specific prompting method is to be set by those skilled in the art according to the actual situation, and will not be elaborated here.
[0072] Step S302: If present, control the test equipment to sequentially adjust to the intermediate range information and obtain the intermediate test result information of the battery.
[0073] If there is an intermediate range between the maximum range information and the final range information, the control test equipment is adjusted to the intermediate range information in ascending order, thereby controlling the test equipment to test the battery in sequence with the intermediate range information, so as to obtain the intermediate test result information of the battery and provide data support for determining the final test result information.
[0074] Battery intermediate test result information refers to the results when the test equipment tests the battery using intermediate range information.
[0075] Step S303: Analyze the battery intermediate test results and battery adjustment test results to determine the final test results.
[0076] In this step, the final test result refers to the high-precision test result obtained by the testing equipment after analyzing the intermediate battery test results and the battery adjustment test results. The specific determination method is detailed in [reference needed]. Figure 4 The steps.
[0077] Reference Figure 4 The method for determining the final test results by analyzing intermediate battery test results and battery adjustment test results includes the following steps: Step S400: Analyze the intermediate test results and battery adjustment test results to determine the error information of the intermediate test results.
[0078] Among them, the intermediate test result error information refers to the error value between the result detected by the test equipment with intermediate range information and the result detected with final range information. It is obtained by the processing system by subtracting the battery intermediate test result information and the battery adjustment test result information and taking the absolute value.
[0079] Step S401: Analyze the intermediate range information and the final range information to determine the intermediate range error information.
[0080] Among them, the intermediate range error information refers to the maximum error value between the current intermediate range information and the final range information when testing the same battery. It is obtained by the processing system after analyzing the intermediate range information and the final range information. The analysis method is as follows: if the final range information is 0 to 200 mA and the intermediate range information is 0 to 300 mA, then the final range information and the intermediate range information are input into the database to match and output the error value. The error value between different ranges is obtained by those skilled in the art after testing the same battery in advance with two ranges, and the error is stored in the database after corresponding one-to-one with the range.
[0081] Step S402: Determine whether the error information of the intermediate test results meets the requirements of the intermediate range error information.
[0082] The requirement for intermediate range error information is that it should not exceed the error value corresponding to the intermediate range error information. By determining whether the error corresponding to the intermediate test result error information is not greater than the error corresponding to the intermediate range error information, it is determined whether the result obtained using the intermediate range information is a high-precision result.
[0083] Step S4021: If it does not meet the requirements, control the testing equipment to adjust to the next intermediate range information and obtain the battery intermediate test result information.
[0084] If the error corresponding to the intermediate test result error information is greater than the error corresponding to the intermediate range error information, it is determined that the accuracy of the result obtained using the intermediate range information is low and cannot be used as data to determine the final test result information. Therefore, the test equipment is controlled to adjust to the next intermediate range information to test the battery again and obtain the intermediate test result information. The intermediate test result information in this step is the same as the intermediate test result information in step S302, and will not be described again here.
[0085] Step S4022: If the condition is met, the battery intermediate test result information is determined to be valid intermediate test result information.
[0086] If the error corresponding to the intermediate test result is not greater than the error corresponding to the intermediate range error, then the result obtained using the intermediate range information is considered to have higher accuracy and can be used as data to determine the final test result. Therefore, the battery intermediate test result is determined to be valid intermediate test result information. Valid intermediate test result information refers to battery intermediate test result information where the error between it and the battery adjustment test result is less than the range error. This information is output by the processing system based on the comparison result that the intermediate test result error is not greater than the intermediate range error.
[0087] Step S403: Obtain the intermediate range test completion trigger information.
[0088] Among them, the intermediate range test completion trigger information refers to the trigger data of the test equipment completing the test on the battery with all intermediate range information. The processing system records the intermediate range information that has been used. When the recorded intermediate range information is exactly the same as the intermediate range information between the final range information and the maximum range information, the intermediate range test completion trigger information is output.
[0089] Step S404: Based on the intermediate range test completion trigger information, analyze the valid intermediate test result information and battery adjustment test result information to determine the final test result information.
[0090] Specifically, after the control test equipment tests the battery with all intermediate range information, that is, when the intermediate range test completion trigger information is detected, the final test result information is obtained by averaging the valid intermediate test result information and the battery adjustment test result information.
[0091] Reference Figure 5 The method for determining the final test result information based on battery adjustment test result information includes the following steps: Step S500: Determine whether the battery adjustment test result information meets the requirements of the preset range endpoint value information.
[0092] The range endpoint information refers to the range endpoint values of the testing equipment, such as 100 mA, 200 mA, 300 mA, 400 mA, and 500 mA. The requirement for the range endpoint information is that it must be equal to the endpoint value corresponding to the range endpoint information.
[0093] By determining whether the result value corresponding to the battery adjustment test result information is equal to the endpoint value corresponding to the range endpoint value information, it is determined whether the result obtained by the test equipment from the final range information is the endpoint value, and thus whether the accuracy of the test result can be further improved.
[0094] Step S501: If it does not meet the requirements, then the battery adjustment test result information is determined as the final test result information.
[0095] If the result value corresponding to the battery adjustment test result information is not equal to the endpoint value corresponding to the range endpoint value information, then it is determined that the result obtained by the test equipment from the final range information is not the endpoint value, and the accuracy of the test result cannot be further improved. Therefore, the battery adjustment test result information is determined to be the final test result information.
[0096] Step S502: If the conditions are met, analyze the battery adjustment test results and the final range information to determine the adjacent range information.
[0097] If the result value corresponding to the battery adjustment test result information is equal to the endpoint value corresponding to the range endpoint value information, then the test equipment is determined to use the result obtained by testing the battery with the final range information as the endpoint value, which can further improve the accuracy of the test result. Therefore, the adjacent range information is determined based on the battery adjustment test result information and the final range information, thereby providing data support for the subsequent determination of the final test result information with higher accuracy.
[0098] Adjacent range information refers to the range that is close to the battery adjustment test result information and adjacent to the final range information. It is obtained by the processing system based on the battery adjustment test result information and the final range information. The analysis method is as follows: for example, if the final range information is 0 to 200 mA and the battery adjustment test result information is 200 mA, then the adjacent range information is 0 to 300 mA.
[0099] Step S503: Control the test equipment to adjust to the adjacent range information to test the battery under test, and obtain the adjacent range test result information.
[0100] In this process, after determining the adjacent range information, the control test equipment is used to test the battery under test with the adjacent range information to obtain the adjacent range test result information. This prevents the decimal part of the endpoint value of the final range information from not being displayed and provides data support for determining the final test result information with higher accuracy.
[0101] Adjacent range test result information refers to the results obtained by the test equipment after testing the battery under test using adjacent range information.
[0102] Step S504: Analyze the adjacent range test results and battery adjustment test results to determine the final test results.
[0103] In this process, after obtaining the test results of adjacent ranges, the processing system calculates the average value of the test results of adjacent ranges and the battery adjustment test results to obtain the final test result information with higher accuracy.
[0104] Reference Figure 6 Before obtaining the battery test results, the method also includes a verification method for the battery under test, which includes the following steps: Step S600: Obtain the battery power information and full battery power information of the battery under test based on the battery connection trigger information.
[0105] Among them, battery power information refers to the power value of the battery under test after being connected to the testing equipment. This power value is detected by the coulomb counter on the testing equipment after the battery connection trigger information is detected, i.e., after the battery under test is connected to the testing equipment. Battery full charge information refers to the full charge value of the battery under test, and the specific value is obtained by those skilled in the art by inputting it into the processing system.
[0106] Step S601: Determine whether the battery power information meets the requirements of the battery full power information.
[0107] The requirement for "full battery charge information" is that it equals the charge value corresponding to the full battery charge information. By determining whether the charge value corresponding to the battery charge information is equal to the charge value corresponding to the full battery charge information, it is possible to determine whether the battery under test is in a fully charged state.
[0108] Step S6011: If the condition is met, control the testing equipment to test the battery under test.
[0109] If the battery power information corresponds to the power value of the battery full power information, it indicates that the battery under test is in a fully charged state. The voltage detected by the battery will not be lower than the voltage of the full power due to insufficient power, thus misleading personnel to confirm that the battery is defective. Therefore, the test equipment is controlled to test the battery under test.
[0110] Step S6012: If it does not meet the requirements, then the battery under test is verified based on the battery power information and the battery full power information.
[0111] If the battery charge information does not correspond to the full charge information, it indicates that the battery under test is in a low-charge state. This low charge may cause the measured voltage to be lower than the full charge voltage, potentially misleading personnel into believing the battery is defective. Therefore, the battery under test must be verified based on both the battery charge and full charge information. Specific verification methods are detailed below. Figure 7 The steps.
[0112] Reference Figure 7 The method for verifying the battery under test based on battery power information and battery full charge information includes the following steps: Step S700: Calculate the difference between the battery full charge information and the battery charge information, and define the calculated difference as the battery low charge information.
[0113] Among them, the battery low power information refers to the difference between the battery power and the full power of the battery under test, which is obtained by the processing system by subtracting the battery full power information from the battery power information.
[0114] Step S701: Determine whether the battery low power information meets the preset requirements for direct charging power information.
[0115] The direct charging capacity information refers to the amount of charge that the test equipment is allowed to directly charge the battery under test. The specific value is set by those skilled in the art based on the actual situation. The requirement for the direct charging capacity information is that it should not be less than the capacity value corresponding to the direct charging capacity information.
[0116] By determining whether the battery charge level corresponding to the low charge information is not less than the charge level corresponding to the direct charge information, it can be determined whether the testing equipment can fully charge the battery under test in a short time without affecting the efficiency of the battery test.
[0117] Step S7011: If not met, output the preset disconnection charging information to prompt the personnel to disconnect the charging.
[0118] If the battery power shortage information corresponds to a power value less than the direct charging power information, it is determined that the test equipment cannot fully charge the battery under test in a short time. In this case, a disconnection charging information is output to prompt the personnel to disconnect the battery under test from the test equipment before charging.
[0119] Step S7012: If the conditions are met, obtain the charging power information of the battery under test.
[0120] Specifically, if the battery depletion information corresponds to a charge value that is not less than the direct charging charge information, it is determined that the testing equipment can fully charge the battery under test in a short time without affecting the efficiency of the battery test. Therefore, the charging power information is detected to provide data for subsequent battery charging by the testing equipment. The charging power information refers to the power value of charging the battery under test, which is obtained by those skilled in the art through input into the processing system.
[0121] Step S702: Control the preset charging device to charge the battery under test with the charging power information, and obtain the charging device's power level unchanged trigger information.
[0122] The charging device refers to a device used to charge the battery under test. The charging device is installed on the testing equipment. In this application, another battery is used as the charging device, and the battery under test is charged through the interface connecting the testing equipment to the positive and negative terminals of the battery. After determining the charging power information, the charging device is controlled to charge the battery under test at the power value corresponding to the charging power information, thereby ensuring that the battery under test is in a fully charged state without affecting the battery test. The device also detects the trigger information indicating that the charge level remains unchanged, providing data support for subsequently stopping charging.
[0123] The constant charge trigger information refers to the trigger data that the charge of the charging device no longer changes when the charging device is charging the battery under test. The charge of the charging device is detected by a coulomb meter. When the charging device is charging the battery under test, the charge continuously decreases, while the constant charge indicates that the battery under test is in a fully charged state.
[0124] Step S703: Based on the unchanged power level trigger information, control the charging device to stop charging.
[0125] Specifically, when a trigger message indicating that the battery level remains unchanged is detected, meaning the charging device's power level is no longer decreasing and the battery under test is at full charge, the charging device is controlled to stop charging. This prevents personnel from mistakenly identifying the battery as defective due to insufficient charge on the battery under test.
