For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] Figure 1 A flowchart of a new energy vehicle battery testing method 100 according to an embodiment of the present disclosure is shown. Method 100 may include: Step 110: Set different test conditions and test items required for testing the battery; The tests included capacity testing, fast charging performance testing, and temperature change testing during the charging process.

[0022] The test conditions include various real-world vehicle operating conditions such as high temperature, low temperature, fast charging, over-discharging, and high-rate discharging.

[0023] Step 120: Adjust the battery testing equipment to the test parameters corresponding to the different test conditions and different test items; Battery testing equipment is connected to the battery. The battery testing equipment can be hardware devices such as battery testing instruments, charging equipment, and discharging equipment.

[0024] Battery testing equipment automatically adjusts test parameters such as test current, charging voltage, and discharge load to simulate battery usage under different operating conditions. Based on preset test conditions, it automatically adjusts charging and discharging parameters, such as high temperature, low temperature, fast charging, and over-discharging. Step 130: After adjusting to the corresponding test parameters, monitor various operating parameters of the battery in real time; Step 140: After the different test items are completed, automatically summarize the various operating parameters of the battery at different time points, the different test conditions and the different test items, and generate a visual test report containing charts and statistical data.

[0025] After the test is completed, all data generated during the test can be collected and summarized to form a final test result report. Then, based on the data analysis results, a detailed battery test report can be generated so that it can be visualized through charts and statistical data to help maintenance personnel make subsequent judgments.

[0026] After setting the different test conditions and test items required for the test battery, the battery testing equipment can be adjusted to the test parameters corresponding to the different test conditions and test items. After adjusting to the corresponding test parameters, various operating parameters of the battery can be monitored in real time. Then, after the different test items are completed, the various operating parameters of the battery at different time points, the different test conditions and the different test items are automatically summarized to generate a visual test report containing charts and statistical data. In this way, the battery testing equipment can be used to automatically complete the automated testing of the battery, thereby avoiding the need for manual testing of the battery using various discrete tools. This can significantly improve the battery testing efficiency and automatically complete the integrated summary to obtain an electronic visual test report, avoiding the need for paper records or scattered storage.

[0027] In some embodiments, various operating parameters of the battery are monitored in real time, including: Real-time monitoring of the total voltage of the battery pack during the charging and discharging process; Real-time monitoring of the individual cell voltages during the charging and discharging process of the battery; High-speed synchronous acquisition of total battery pack voltage, individual cell voltage, or module voltage during battery charging and discharging can be achieved using high-precision ADC chips and multiplexers. The magnitude and direction of the current during the charging and discharging process of the battery are monitored in real time. High-precision Hall current sensors can be used to monitor the magnitude and direction of the current during the charging and discharging process in real time.

[0028] Real-time monitoring of the temperature of individual cells during the charging and discharging process of the battery; A multi-channel temperature sensor interface connects to temperature probes attached to key parts of the battery casing to detect the temperature of individual battery cells.

[0029] In some embodiments, prior to debugging, the method further includes: After the battery testing equipment is connected to the battery via a test fixture, the current connection resistance of the test fixture is measured. Obtain the fixture resistance threshold; Determine whether the current connection resistance is less than the fixture resistance threshold; If the value is less than the specified value, then the test fixture is confirmed to be properly connected. Before starting the test, it is necessary to determine whether the connection between the test fixture and the battery electrode is firm and reliable to avoid loose connection and arcing; specifically, if the current connection resistance is less than the fixture resistance threshold, it indicates that the test fixture is well connected.

[0030] or Before debugging, the method also includes: Measure the current insulation resistance between the positive and negative terminals of the battery and the battery casing; Obtain the insulation resistance threshold; Determine whether the current insulation resistance is greater than the insulation resistance threshold; If the value is greater than the specified value, it confirms that the positive and negative terminals of the battery are well insulated from the battery casing.

[0031] The current insulation resistance between the positive and negative terminals of the battery pack and the outer casing can be measured. Then, the current insulation resistance is compared with the insulation resistance threshold to determine whether the insulation is good. Specifically, if the current insulation resistance is greater than the insulation resistance threshold, it means that the current insulation resistance is large enough. Therefore, it can be confirmed that the insulation between the positive and negative terminals of the battery and the battery casing is good and there is no leakage.

[0032] In some embodiments, a circuit breaker is provided in the connection path between the battery testing equipment and the battery; The method further includes: Obtain the preset current safety threshold; If the current during the battery charging and discharging process exceeds the preset current safety threshold, the circuit breaker will be activated.

[0033] The circuit breaker can be a preset high-current fast circuit breaker. Once the current during the battery charging and discharging process exceeds the preset current safety threshold, it indicates that a short-circuit current has been detected. Therefore, the circuit breaker can be activated to cut off the circuit within microseconds. If necessary, the battery test can be interrupted in an emergency, which facilitates data backup while interrupting the test.

[0034] In some embodiments, the method further includes: Obtain preset warning thresholds corresponding to various operating parameters of the battery; Each battery operating parameter is determined to see if it exceeds the corresponding preset warning threshold, and the determination result is obtained. If the judgment result is that any one of the various operating parameters of the battery exceeds the corresponding preset warning threshold, then a warning reminder for the any one operating parameter is generated, and the test parameters corresponding to the any one operating parameter are adjusted.

[0035] After obtaining the preset warning thresholds corresponding to various operating parameters of the battery, it can be determined whether each operating parameter exceeds the corresponding preset warning threshold, and the judgment result is obtained. If the judgment result is that any operating parameter exceeds the corresponding preset warning threshold, it indicates that the operating parameter is abnormal. Therefore, a warning reminder for the operating parameter can be generated, such as issuing an alarm. The operating parameter can also be highlighted, and the test parameters corresponding to the operating parameter can be adjusted to retest the operating parameter to avoid false tests.

[0036] In some embodiments, the method further includes: Obtain historical operating parameters corresponding to various operating parameters of the battery; The various operating parameters of the battery are compared with the corresponding historical operating parameters to obtain the comparison results of the battery's operating parameters. Based on the comparison results and the visualization test report, a health status assessment of the battery is generated.

[0037] By comparing and analyzing the collected operating parameters with the corresponding historical operating parameters, the change curves of various operating parameters and whether the changes are good can be confirmed, thereby obtaining the comparison results of the battery's operating parameters. Then, based on the comparison results and the visualization test report, an accurate health status assessment of the battery can be automatically generated.

[0038] In some embodiments, the method further includes: After the battery testing equipment is connected to the battery, a test control command is sent to the battery testing equipment; According to the test control command, the battery test equipment is controlled to perform corresponding operations, including starting, stopping, and adjusting the test parameters.

[0039] After the battery testing equipment is connected to the battery, a test control command can be sent to the battery testing equipment. Then, according to the test control command, the battery testing equipment can be automatically controlled to start, stop, and adjust the test parameters, thereby automatically controlling the testing process of the battery testing equipment.

[0040] Of course, the order in which test control commands are sent can also be monitored during battery testing to ensure the execution order of the battery testing equipment. This allows for the scheduling and control of the hardware testing equipment according to test requirements, while generating detailed battery test reports that display key data such as the battery's health status and charge / discharge performance.

[0041] A method for testing batteries for new energy vehicles includes the following specific steps: S1. Connect the battery under repair to the test platform and manually pre-set the test parameters and test items corresponding to the test conditions; S2. Monitor various battery parameters in real time and compare and analyze the collected data with historical data. Battery parameters include voltage, current, and temperature, and these parameters can be manually deleted or added. S3. Automatically control the hardware equipment according to the preset test scenario, adjust the test current, voltage and load, simulate different battery working conditions, the test current includes the battery pack capacity test current, discharge the battery pack to the cutoff voltage with a constant current through a programmable load, and calculate the actual capacity of the battery pack based on the discharge current and time. S4. After the test is completed, the test platform automatically summarizes all test data, generates a visual test report containing charts and statistical data, and uploads all the running data and results of this test to the data backup center for secure storage.

[0042] Example When a certain brand of electric vehicle's battery pack is connected to this test system: S1. The staff first connects the battery pack to be tested to the hardware equipment of the test platform, logs into the visual interface of the maintenance control terminal, and manually selects the parameters that need to be focused on in this test in the battery parameter preset unit: total voltage, minimum single cell voltage, maximum temperature difference, charging and discharging current, and sets warning thresholds for these parameters. The alarm threshold for single-unit voltage difference is 300mV; The maximum temperature alarm threshold is 60℃; Select capacity test and fast charging performance test as the test items in the test hardware device control unit; S2. Before starting the test, the battery testing system automatically executes a safety self-test procedure. It first starts by connecting to the diagnostic unit, measuring the insulation resistance between the positive and negative terminals of the battery pack and the outer casing. If the value is >500Ω / V, it meets the safety standard. At the same time, it detects that the connection resistance of all test fixtures is <1mΩ. After the self-test passes, the battery testing system officially starts. The battery parameter acquisition module starts working, and high-speed synchronously acquires the total voltage of the battery pack and the voltage of all individual cells through a multiplexer. The data is displayed in real time on the maintenance control screen and automatically generates a voltage distribution curve. The current acquisition unit monitors the current in real time through Hall sensors and records the current fluctuations during charging and discharging. The temperature acquisition unit monitors and displays the temperature cloud map in real time through 12 temperature probes distributed on the battery box. All acquired data is compared and analyzed in real time with the historical health data model in the database. S3. The testing platform automatically executes tests based on preset items: Capacity test: The multi-functional test unit controls the programmable load to discharge the battery pack with a constant current of 1C (100A) until the battery test system detects that the voltage of a single cell reaches the discharge cutoff voltage (2.8V). Throughout the process, the safety management unit continuously monitors all parameters. When the battery test system detects that the maximum temperature difference between modules reaches the preset 5℃ warning line, a yellow warning prompt will immediately pop up on the interface, but the interruption threshold is not reached and the test continues. Fast charging performance test: After the capacity test, the battery test system automatically switched to fast charging test. The test hardware control unit controlled the charger to charge the battery pack at a high rate (1.5C) current. The safety management unit detected that the lowest single cell voltage jumped too fast at the end of the charging stage, which triggered the battery test system's preset voltage abnormality warning rule. The system protection unit did not activate the emergency circuit breaker. Instead, the multi-functional test unit automatically executed the preset processing plan: smoothly reduce the charging current to 0.5C until charging is complete. S4. After the test is completed, the test result summary unit automatically generates a complete test report. The report shows that the actual capacity of the battery pack is only 68% of the rated capacity, confirming severe capacity decay. During fast charging, the voltage and temperature of the No. 12 cell are significantly abnormal, indicating that there is a faulty cell in this module. The report clearly shows the charge and discharge curves, voltage-temperature change curves, etc. in the form of charts and graphs, and directly points out the root cause of the problem. The battery test data backup center automatically encrypts and stores all the original data, operation logs and final report of this test for subsequent quality traceability and big data analysis.

[0043] Specifically: In practical applications, it has multiple battery parameter acquisition modules, which are used in conjunction with the testing platform and safety management device.

[0044] Multiple battery parameter acquisition modules are located in different geographical locations. In actual use, they can collect multi-dimensional parameters such as the total voltage of the battery pack, the voltage of each cell, current, and temperature at high speed. They also have the ability to compare and analyze with historical data models, thereby achieving in-depth insight and accurate assessment of the battery health status, far exceeding the detection capabilities of traditional discrete tools.

[0045] The multi-functional testing unit in the testing platform can automatically simulate various real-world vehicle operating conditions such as high temperature, low temperature, fast charging, and high-rate discharge.

[0046] The safety management devices form a comprehensive safety barrier from prevention to intervention. Specifically, insulation testing and connection reliability assessment can be automatically performed before testing to prevent accidents at the source. Meanwhile, the microsecond-level fast circuit breaker can instantly cut off the circuit when an anomaly occurs, thereby maximizing the safety of personnel and equipment. The previously cumbersome and manual processes have been integrated into an automated and integrated testing solution, which significantly shortens the diagnosis time and reduces the intensity of manual labor. The management, visualization, and storage of battery test data and corresponding analysis results help to realize battery test management through IoT cloud control and improve the level of intelligence in battery test management.
