Cell Degradation Diagnostics
Function
Utilizes BMS data (voltage, current, and positional information [C-R-M-C]) to detect degraded cells and
diagnose their condition through analysis of extraction frequency and degradation stage.
Key features
Detection of degraded cells using continuous operational data
Stage-by-stage degradation diagnosis based on inspection and analysis of detected cell data
User-defined reporting cycle for providing location and stage of degraded cells
Expected benefits
Traceable management based on relative positional information of degraded cells
Periodic (daily or weekly) degradation assessment and optimized maintenance
Early prediction of fire risks based on the frequency of degradation in specific cells
Results
Fire risk prevention enabled through degraded cell detection during operation
Degraded cell diagnosis results
DB-based degraded cell detection results
Demonstration results
- 50MW utility-scale ESS demonstration results (provision of data-based degraded cell extraction results over a specified period)
Precision diagnosis (DC-IR measurement) results
Demonstration results
- Reliability was established through comparative analysis of degraded cell extraction results during operation and precision diagnosis (using DC-IR measurement).
