5. Overview of test procedures
1.Initial Test: Under standard environmental conditions, the battery module is subjected to initial tests on appearance, basic functions, and electrical performance.
2.Sample Placement: Place the battery module in the test chamber to ensure that it is in normal working condition.
3.Setting Parameters: Set the parameters such as dust concentration, airflow speed, temperature, humidity, test time, etc. according to the test standard or customer's requirement.
4.Start the test: Start the test chamber and begin the sand and dust test.
5.
Continuous monitoring: During the test, monitor the performance and status of the battery module regularly and record the relevant data.
6.End of test: After the test, take out the samples, carry out appearance and function check, and evaluate the test results.
6. Evaluation Criteria
- Appearance Inspection: Check whether there is any dust deposition on the surface of the battery module and whether there is any dust entry in the sealed part.
- Function test: Test whether the functions of the battery module are normal and whether it is affected by sand and dust.
- Sealing test: Evaluate the sealing performance of the battery module to ensure that dust will not enter the interior and affect its normal operation.
- Electrical performance: Test whether the electrical performance of the battery module is affected, such as voltage, current, internal resistance and so on.
- Safety performance: Test the safety performance of the battery module to ensure that no short circuit, overheating, explosion and other safety problems will occur in the sand and dust environment.
7. Precautions
- Safe Operation: Operators should wear protective equipment, such as dust masks and protective glasses.
- Equipment Maintenance: Regularly check and maintain the equipment to ensure its normal operation, especially the sand dust generator and airflow control system.
- Dust Recycling: Recycle dust after use to avoid environmental pollution.
- Temperature and humidity control: Ensure the uniformity of temperature and humidity in the test chamber to avoid localized overheating or overhumidity.
- Environmental control: Keep the test environment clean to avoid external dust affecting the test results.
