Depth of Discharge Based Degradation
Upload battery degradation data based on Depth of Discharge (DoD), showing how capacity loss increases with cycle count for different DoD levels.
File Requirements
| Property | Value |
|---|---|
| File Format | Excel (.xlsx) or CSV |
| Required Columns | cycle_count, depth_of_discharge_20_percent, depth_of_discharge_50_percent, depth_of_discharge_80_percent |
| Units | Cycle count as integer, capacity loss as percentage (%) |
| Excel Sheet Name | DEGRADATION-TABLE |
Understanding the Data
This dataset represents how a battery degrades over time depending on how deeply it is discharged during each cycle.
Each row corresponds to a specific cycle count, and each column represents the cumulative capacity loss at a given Depth of Discharge (DoD).
Step-by-Step Instructions
LFP battery with manufacturer cycle-life data at different DoD levels:
- Fill the first row (0 cycles) with 0% loss for all DoD levels, then add a row for each cycle milestone in your manufacturer data.
Example: at 100 cycles — 0.16% (20% DoD), 0.40% (50% DoD), 0.63% (80% DoD).
- Continue adding milestone rows until you have covered the full expected cycle life of your battery.
Example: at 1,000 cycles — 1.61% (20% DoD), 4.04% (50% DoD), 6.46% (80% DoD).
- Place your completed data in the DEGRADATION-TABLE sheet using the required column headers.
Column names must exactly match those shown in the example CSV below.
- Save the file and upload it
Check that capacity loss values increase monotonically down each column, and that 80% DoD ≥ 50% DoD ≥ 20% DoD at every row.
Summary
You are uploading a degradation profile that defines how battery capacity reduces over time at different Depth of Discharge levels. This allows the system to accurately model battery performance and lifetime under varying usage conditions.
