High-temperature testing and inspection of electric vehicle intelligent battery swap cabinets is an important part of ensuring their performance stability and safety. The following are the main methods for conducting such high-temperature tests and inspections:

1. Test Preparation
Test equipment:
High-temperature box (or high-temperature chamber): used to provide a certain high-temperature environment to simulate the working conditions of the battery swap cabinet under extremely high temperatures.
Thermometer: used to measure and monitor the test temperature to ensure the accuracy of the test environment.
Measurement system: used to measure the electrical performance parameters of the battery swap cabinet, such as voltage, current, etc.
Test sample:
Select a representative electric vehicle intelligent battery swap cabinet as the test sample to ensure that the sample meets the relevant standards and specifications.
Test conditions:
According to relevant standards and specifications, set the test temperature range, usually 60℃~80℃.
Determine the test time, the specific time depends on the test conditions and equipment requirements and may range from several hours to dozens of hours.
2. Test steps
Initial inspection:
Perform an appearance inspection on the test sample to ensure that the battery swap cabinet has no obvious damage or defects.
Test the electrical and mechanical properties of the battery swap cabinet and record the initial data.
Build the test environment:
Place the battery swap cabinet in a high-temperature box (or high-temperature room) and connect relevant test equipment.
Ensure that the components and batteries in the battery swap cabinet can work normally and are in a safe state.
Preheating stage:
Gradually increase the temperature in the high-temperature box (or high-temperature room) to a predetermined value, so that the components and batteries in the battery swap cabinet gradually adapt to the high-temperature environment.
Testing stage:
After reaching the predetermined temperature, conduct a continuous working test on the battery swap cabinet.
Monitor the voltage, current, temperature, and other parameters of the battery swap cabinet and record relevant data.
Observe the heat dissipation performance, material temperature resistance, and reliability of the battery management system of the battery swap cabinet in a high-temperature environment.
Intermediate testing:
During the test, perform performance testing on the test samples in accordance with the relevant specifications to ensure that the battery swap cabinet can work normally in a high-temperature environment.
Recovery stage:
After the test, gradually reduce the temperature in the high-temperature box (or high-temperature room) to room temperature to restore the battery swap cabinet to a normal working environment.
Final testing:
Perform an appearance inspection, and electrical and mechanical performance tests on the test samples to ensure that the battery swap cabinet can still work normally after undergoing a high-temperature test.
3. Test data analysis and evaluation
Data analysis:
Analyze the data recorded during the test, including the changes in the voltage, current, temperature, and other parameters of the battery swap cabinet.
Evaluate the heat dissipation performance, material temperature resistance, and reliability of the battery management system of the battery swap cabinet in a high-temperature environment.
Evaluation report:
Write a test evaluation report based on the data analysis results.
The report should include the purpose of the test, test methods, test conditions, test results, and evaluation conclusions.
4. Precautions
Test safety:
When conducting high-temperature tests, the safety of the test environment should be ensured to prevent safety accidents such as fire and explosion caused by high temperatures.
Operators should wear protective equipment to ensure personal safety.
Test accuracy:
Ensure the accuracy and reliability of the test equipment to avoid test errors caused by equipment failure.
Strictly conduct tests in accordance with relevant standards and specifications to ensure the accuracy and reliability of the test results.
In summary, the methods of high-temperature test, inspection, and testing of electric vehicle intelligent battery swap cabinets include test preparation, test steps, test data analysis and evaluation, and precautions. Through high-temperature tests, we can fully understand the performance of the battery swap cabinet in a high-temperature environment and provide strong guarantees for the safe operation of new energy vehicles.
