DIN EN 62620 Mechanical Abuse Testing of Large Lithium-Ion Cells
The DIN EN 62620 standard is designed to ensure the safe and reliable operation of large lithium-ion cells used in various applications, including electric vehicles, energy storage systems (ESS), and other battery-intensive industries. This test specifically addresses mechanical abuse scenarios that may occur during the lifecycle of these batteries. By subjecting large lithium-ion cells to controlled stress conditions, we can assess their robustness against potential hazards such as puncture, crush, vibration, and over-temperature.
The testing protocol outlined in DIN EN 62620 is crucial for manufacturers seeking to comply with international safety regulations while also ensuring the durability of their products. The standard covers a range of mechanical abuse tests that are essential for assessing the structural integrity and electrical performance of large lithium-ion cells. These tests not only help identify potential weaknesses but also provide valuable insights into how these batteries will behave under real-world conditions.
Our facility is equipped with advanced testing machines capable of simulating various types of mechanical abuse, including puncture using a sharp object, crush testing at specified pressure levels, and vibration exposure. For each test, we follow precise procedures outlined in the standard to ensure accurate results. Post-testing analysis includes both visual inspection for physical damage and electrical performance checks to evaluate internal short circuits or other issues.
The importance of this testing cannot be overstated given the increasing demand for safer, more reliable batteries across multiple sectors. For instance, electric vehicle manufacturers need to guarantee that their vehicles can withstand unexpected impacts without risking passenger safety. Similarly, energy storage system operators must ensure their installations remain stable even during extreme weather conditions or accidental mechanical incidents.
By adhering strictly to DIN EN 62620 guidelines and using state-of-the-art equipment, we offer comprehensive testing services that meet global standards while providing detailed reports tailored to each client's needs. Whether you're developing new products or simply ensuring existing ones comply with regulatory requirements, our expertise ensures peace of mind knowing your batteries are thoroughly tested against all relevant scenarios.
| Test Type | Description | Equipment Used |
|---|---|---|
| Puncture Test | A sharp object is used to simulate a puncture, assessing the cell’s resistance to penetration by external forces. | High-strength steel needle or similar tool. |
| Crush Test | The battery is subjected to high pressure to mimic potential damage from crushing events like vehicle accidents. | Hydraulic press with adjustable load capacity. |
In addition, our facility also offers additional services such as thermal cycling tests and accelerated aging tests which complement the mechanical abuse testing provided under DIN EN 62620. These supplementary tests further enhance confidence in product quality by simulating long-term operational stresses that may not be captured solely through physical impact assessments.
| Test Type | Description | Equipment Used |
|---|---|---|
| Thermal Cycling Test | The battery undergoes repeated cycles of temperature extremes to evaluate its performance and stability over time. | Climate chamber capable of precise temperature control. |
| Accelerated Aging Test | This test simulates the effects of prolonged use by exposing batteries to harsh environmental conditions more rapidly than actual usage. | Environmental stress screening equipment including humidity chambers and vibration testers. |
The combination of these tests provides a holistic approach to ensuring the safety, reliability, and longevity of large lithium-ion cells. Our experienced team of engineers ensures each test is conducted meticulously according to DIN EN 62620 specifications, delivering accurate results that are both reproducible and comparable internationally.
Applied Standards
DIN EN 62620:2017-09 specifies the mechanical abuse tests for large lithium-ion cells intended to be used in various applications. The standard covers three main types of tests:
- Puncture Test (Paragraph 5.4)
- Crush Test (Paragraph 5.6)
- Vibration Test (Paragraph 5.7)
These tests are aimed at evaluating the mechanical robustness and electrical performance of large lithium-ion cells under extreme conditions that might be encountered during their lifecycle.
| Test Type | Description | Key Points |
|---|---|---|
| Puncture Test | The cell is punctured using a sharp object to simulate accidental damage from external sources like nails or rocks. | The depth of penetration and any resulting short circuits are recorded. |
| Crush Test | The cell is compressed between two plates at specified loads to assess its ability to withstand mechanical pressure. | Load capacity ranges from 50 kN up to 100 kN, depending on the size of the battery. |
| Vibration Test | The cell is subjected to controlled vibration frequencies and amplitudes over a specified duration to simulate transport or handling conditions. | Frequency range from 2 Hz to 500 Hz with amplitude up to ±1 mm. |
Each test requires careful preparation of the sample, including ensuring that it is free from defects and properly charged according to the standard's instructions. Post-test analysis involves visual inspection for physical damage as well as electrical performance checks using ohmmeters or similar devices to detect internal shorts or other malfunctions.
