KTBIX-Generated Dataset (WP1)
The primary novel contribution of WP1 is a new open industrial EIS dataset from real EV platforms:
| Property | Details |
|---|---|
| Platform | Turkish T-EV electric vehicles + TOGG T10X |
| Chemistry | NMC (primary), LFP (secondary) |
| Capacity | 50–100 Ah (cell level) |
| SOH range | ~60% – 100% |
| Conditions | Field duty cycles, ambient temperatures |
| Frequency points | 51 per spectrum, 10 mHz – 100 kHz |
| Target size | ≥500 EIS spectra with paired SOH ground truth |
| License | CC BY 4.0 |
| Repository | Zenodo (DOI to be assigned at project end) |
Data Policy
All KTBIX-generated datasets will be released as open data under CC BY 4.0 at project completion (M24), deposited on Zenodo with full documentation. Code will be released on GitHub under MIT license.
