IEC 60068-2-38 Composite Temperature and Humidity Environmental Stress Testing of Cells
The IEC 60068-2-38 standard provides a method for testing the durability, reliability, and performance of lithium-ion cells under composite temperature and humidity conditions. This environmental stress test is essential for ensuring that battery cells can withstand real-world operating environments. The composite cycling protocol combines temperature and humidity variations to simulate the impact of harsh weather conditions, such as those encountered during transportation or storage.
The standard specifies a series of procedures for simulating various combinations of temperature and relative humidity levels over specified time periods. It is important to note that this testing method is not intended to replicate specific environmental conditions but rather provides a standardized approach to evaluate the robustness of batteries under a range of environmental stresses. This comprehensive testing helps manufacturers identify potential weaknesses in their designs, ensuring product performance across diverse applications.
The test setup involves placing battery cells into a controlled environment chamber that can precisely regulate both temperature and relative humidity. The specimens are subjected to pre-determined cycling sequences, which include periods of high and low temperatures along with varying levels of humidity. These cycles are designed to challenge the cell's ability to maintain its operational characteristics while enduring the stresses imposed by environmental factors.
One key aspect of this testing method is the use of composite temperature and humidity profiles. Unlike simpler tests that might focus on one variable at a time, IEC 60068-2-38 allows for simultaneous changes in both parameters. This approach provides a more accurate representation of real-world conditions where temperature and humidity often fluctuate together rather than independently.
Another important feature is the provision for multiple cycles, each with its own set of environmental parameters. By repeating these cycles over extended periods, testers can assess long-term effects on battery performance, durability, and safety. This prolonged exposure helps uncover any latent issues that might not be apparent from shorter-duration tests.
The IEC 60068-2-38 protocol also includes detailed acceptance criteria for evaluating the results of these environmental stress tests. These criteria specify acceptable limits for changes in various cell properties after undergoing specified cycles. Compliance with these criteria ensures that batteries meet the required standards and can be trusted to perform reliably under diverse conditions.
Understanding how this testing method works is crucial for quality managers, compliance officers, R&D engineers, and procurement professionals involved in the development and certification of lithium-ion cells. By leveraging IEC 60068-2-38, organizations can ensure that their products are robust enough to meet market demands while minimizing risks associated with potential failures due to environmental stresses.
