IEC 60068-2-5 Solar Radiation Environmental Stress Testing of Battery Cells
The IEC 60068-2-5 standard is a crucial part of environmental stress testing for battery cells. This international standard ensures that the performance and durability of batteries are evaluated under conditions that mimic real-world exposure to solar radiation. Solar radiation, especially ultraviolet (UV) light, can degrade battery materials over time, leading to reduced lifespan and performance. By subjecting battery cells to controlled solar radiation tests according to IEC 60068-2-5, manufacturers can identify potential weaknesses early in the development process.
This testing is particularly important for automotive, aerospace, and consumer electronics industries where batteries are exposed to varying levels of sunlight. The test not only helps in enhancing the product's quality but also ensures compliance with international standards, thereby increasing market confidence.
The procedure involves exposing battery specimens to a specific spectrum of solar radiation that closely mimics natural conditions found around the globe. This exposure is controlled and monitored using specialized equipment designed to simulate real-world environmental stressors accurately. The test parameters are meticulously defined in IEC 60068-2-5, ensuring consistency across different laboratories.
During the test, battery cells undergo both static and dynamic conditions that can affect their performance. Static testing involves holding the batteries under solar radiation for extended periods to observe any changes in their electrical characteristics or physical integrity. Dynamic testing simulates real-world conditions by cycling the batteries through various charge-discharge cycles while exposed to solar radiation.
The acceptance criteria for this test are stringent, ensuring that only high-quality battery cells meet the standards set forth by IEC 60068-2-5. Compliance with these standards is not just about meeting regulatory requirements but also about enhancing product reliability and safety. By adhering to strict acceptance criteria, manufacturers can ensure their products perform reliably under diverse environmental conditions.
In summary, the IEC 60068-2-5 test is a critical step in the quality assurance process for battery cells. It provides valuable insights into how well batteries withstand solar radiation, helping to improve product design and performance. This testing ensures that products are not only reliable but also safe for use across various applications.

Scope and Methodology
The scope of IEC 60068-2-5 Solar Radiation Environmental Stress Testing involves evaluating the performance of battery cells under controlled solar radiation conditions. This includes assessing the impact of ultraviolet (UV) light on the battery's materials, structure, and electrical properties.
| Criteria | Description |
|---|---|
| Electrical Performance | Battery cells must maintain their rated capacity after exposure. |
| Mechanical Integrity | No visible signs of damage or deformation are allowed. |
| Chemical Stability | The chemical composition must remain stable post-exposure. |
The methodology for conducting this test involves several key steps. First, the battery cells are prepared according to specific guidelines provided in IEC 60068-2-5. This includes cleaning and conditioning the cells to ensure they are in optimal condition before testing.
Next, the specimens are exposed to a controlled solar radiation source for the specified duration and intensity levels. During this exposure, continuous monitoring is carried out using specialized equipment that records various parameters such as temperature, voltage, current, and any changes in physical appearance.
The test concludes with a thorough inspection of each battery cell to determine if it meets all acceptance criteria. Any discrepancies or failures are documented meticulously for further analysis. This ensures that only batteries meeting the stringent requirements are deemed fit for use.
