Reliability Testing of Battery Cells, Lithium Capacitors, and Supercapacitors

In server power systems and BBU (Battery Backup Unit) applications, the reliability of battery cells is a critical factor for data security and backup stability. As an emergency backup power module, the BBU must activate within milliseconds during sudden power outages and maintain the capability to remain on standby for years without failure. Reliability testing simulates long-term operation and extreme stress conditions in data center environments to proactively identify potential failure risks, ensuring the battery cells maintain stable performance throughout the product lifecycle.

• Supports Regulatory Test Applications

  The Chroma 17010/17010H supports multiple test conditions per the IEC62620 international standard, including high-rate C-rate discharge testing, DCIR testing, cycle durability testing, and integrated high/low temperature testing using third-party safety environmental chambers. This provides a one-stop solution for certification requirements.

• Provides DVA Degradation Testing Solutions

  The Chroma 17208M-5-12C, part of the 17010 series, is a high-precision charge-discharge test device specifically designed for battery degradation analysis. It is suitable for applications such as Coulomb Efficiency (CE) analysis, Incremental Capacity Analysis (ICA), and Differential Voltage Analysis (DVA). The system delivers stable current output throughout extended testing periods, ensuring precision and minimizing noise caused by measurement fluctuations, resulting in high-quality test data without the need for post-processing.

Lithium-Ion Capacitor Durability Testing

With the growing diversity of AI applications, the power demand for high-density integrated AI GPUs used in training and inference with large language models (LLMs) continues to rise. Rapidly and reliably delivering peak power to prevent interruptions during AI GPU computations has become a critical challenge for data centers. Capacitor Energy Storage Systems (CESS), primarily using lithium-ion capacitors (LIC), are regarded as a key solution for backup power.

• Provides IEC 62813 Sub-Test Solutions

  The Chroma 17010/17010H systems feature test sequences compliant with IEC 62813 standards, enabling users to perform capacitance and DC resistance (DCR) tests. This facilitates classification of the tested items based on results.

• Supports LIC Durability Testing

  To ensure lithium-ion capacitors (LICs) used in Capacitor Energy Storage Systems (CESS) can reliably deliver stable high-power backup over extended periods, performance degradation verification is conducted during selection. The 17010/17010H systems offer low output noise and high measurement accuracy for cycle durability testing, providing high-quality data to effectively evaluate LIC characteristics.
