Create New Cell Type :
- Name, manufacturer, cell format
- Nominal Capacity [Ah]
- 1kHz Internal Resistance [mΩ]
- Maximum charge rate (A or C-rate)
- Maximum Voltage [V]
- EIS Excitation (optional)
Create New Batch
Classifier Configuration : for each cell type, choose upper and lower limits for
- OCV
- Resistance at 1 kHz
- Ohmic Resistance
- Charge Transfer Resistance
- Low-frequency Resistance
How is the rating/quality score calculated?
With an ICR18650-26H cell
Nominal Capacity 2.6 Ah || IR 100.0 mΩ || Max Charge Rate 2.6 A || Max Voltage 4.2 V
Results of the measure: OCV 4.01 V || IR 62.97 mΩ
Changing the parameters of the cell model in Safion database doesn’t impact the quality score (these parameters are simply used as reference)
Conclusion with Safion engineers: the absolute quality score is not an absolute value but evolves when measuring new cells ⇒ better to refer to the relative quality score to compare cells of a single model/batch
