[0030] Optionally, by setting up a charge / discharge control module 5 and an environmental simulation control module 6, a hierarchical control path with dedicated commands is constructed. The charge / discharge control module 5 is connected to the central controller 1 and the charge / discharge device 2 via control wiring harness 8. As a command relay and execution unit, it receives digital commands (such as start / stop, mode switching, and voltage / current setpoints) issued by the central controller 1 and converts them into drive signals recognizable by the charge / discharge device 2, thereby achieving precise closed-loop control of the charge / discharge process.

The status monitoring and visualization module is responsible for real-time synchronization with the central controller 1 and the Internet of Things (IoT), receiving and parsing operating status data uploaded by devices such as the charging / discharging device 2 and the environmental simulation device 4. It presents the device's operating parameters (such as voltage, current, temperature, humidity, and operating mode) in real-time in a visual format such as charts and indicator lights, enabling remote and transparent monitoring of the equipment status at the test site. The test data query and analysis module provides structured storage, conditional query, and trend analysis functions for historical and real-time test data. Users can use this module to retrieve test process data and result records by time, test item, contract number, battery code, etc., and supports data export and graphical analysis, facilitating traceability and performance evaluation of the test process. The remote control and parameter setting module has the ability to send control commands to the central controller 1, enabling remote adjustment of parameters such as the start / stop of the charging / discharging device 2, switching of charging / discharging modes, setting of current and voltage, and setting of parameters such as target temperature and humidity of the environmental simulation device 4. The alarm and notification management module monitors the system's operational status and test data in real time. When equipment malfunctions, parameter exceedances, or test interruptions occur, it automatically triggers a multi-level alarm mechanism, promptly notifying relevant personnel via push notifications and SMS.

The central controller 1 issues an instruction to the environmental simulation control module 6. The environmental simulation control module 6 automatically sets the target temperature of the environmental simulation device 4. The energy storage battery 3 under test stands in the target temperature environment for a hours. After the standing time ends, the central controller 1 issues an instruction to the charge-discharge control module 5. The charge-discharge control module 5 controls the charge-discharge device 2 to perform charging and discharging operations. After completing multiple charge-discharge cycles, the charge-discharge device 2 transmits the collected data to the central controller 1. After the central controller 1 reads the test data, it performs analysis and calculation to obtain the test result, and automatically determines whether the test result is qualified. If it is qualified, proceed to the next test. If it is unqualified, terminate the test and send the unqualified result to the remote terminal 7 in the form of a notice to inform the test personnel in time; The fourth step involves conducting a mid-temperature electrical performance test. The central controller 1 sends a command to the environmental simulation control module 6, which automatically sets the target temperature for the environmental simulation device 4. The tested energy storage battery 3 is left to stand at this target temperature for b hours. After the standing time ends, the central controller 1 sends a command to the charge and discharge control module 5, which controls the charge and discharge device 2 to perform charging and discharging operations. After completing multiple charge and discharge cycles, the charge and discharge device 2 transmits the collected data to the central controller 1. The central controller 1 reads the test data, analyzes and calculates the test results, and automatically determines whether the test results are qualified. If qualified, the next test is conducted; if unqualified, the test is terminated, and the unqualified result is sent to the remote terminal 7 in the form of a notification to inform the test personnel in a timely manner. The fifth step is to conduct a high-temperature electrical performance test.

The tested energy storage battery 3 is left to stand at the target temperature for c hours. After the standing time ends, the central controller 1 sends an instruction to the charge and discharge control module 5, which controls the charge and discharge device 2 to perform charging and discharging operations. After completing multiple charge and discharge cycles, the charge and discharge device 2 transmits the collected data to the central controller 1. The central controller 1 reads the test data, analyzes and calculates it to obtain the test results, and automatically determines whether the test results are qualified. Step 6: The test ends. The central controller 1 sends a notification to the remote terminal 7 to inform the testers that the test is over. Step 7: Output the test report. After the temperature of the environmental simulation device 4 returns to normal, the test personnel will disconnect the charging and discharging device 2 and the test energy storage battery 3.

[0047] By constructing a highly automated and intelligent testing process, unattended continuous testing of the electrical performance of energy storage battery 3 under multiple temperature conditions was achieved. The benefits are as follows: First, the system automates everything from parameter reading, temperature setting, static control to charge / discharge cycle execution, completely eliminating reliance on manual supervision and offline operations, significantly reducing human resources and waiting time costs, and ensuring a high degree of continuity and consistency in the testing process. Second, the system can automatically calculate and determine pass / fail at each temperature stage based on real-time collected data. If a failure is detected, subsequent testing can be immediately terminated, avoiding the continuation of invalid testing and improving testing efficiency and resource utilization. Simultaneously, the status, results, and anomalies of the testing process can be notified in real time via a remote terminal 7, allowing test personnel to grasp the overall situation without being physically present, achieving remote transparent monitoring and management of the testing process. Finally, the automatic generation and output of test reports further liberates manual labor from tedious data processing, comprehensively improving the overall efficiency, reliability, and standardization of testing operations.

If qualified, the next test is carried out; if unqualified, the test is terminated, and the unqualified result is sent to the remote terminal 7 in the form of a notification to inform the test personnel in a timely manner. The fifth step is to conduct a high-temperature electrical performance test. The central controller 1 sends an instruction to the environmental simulation control module 6, which automatically sets the temperature of the environmental simulation device 4 to 45°C. The tested energy storage battery 3 is placed in this target temperature environment for 16 hours. After the standing time ends, the central controller 1 sends an instruction to the charge and discharge control module 5, which controls the charge and discharge equipment to perform charging and discharging operations. After completing multiple charge and discharge cycles, the charge and discharge equipment transmits the collected data to the central controller 1. The central controller 1 reads the test data, analyzes and calculates it to obtain the test results, and automatically determines whether the test results are qualified. Step 6: The test ends. The central controller 1 sends a notification to the remote terminal 7 to inform the testers that the test is over. Step 7: Output the test report. After the temperature of the environmental simulation device 4 returns to normal, the test personnel will disconnect the charging and discharging equipment and the test energy storage battery 3. The entire test is then completed.
