Profiles measured

DST, US06, FUDS, HWFET, LA92, NN (Neural Network — Kollmeyer custom), Cycle_1..Cycle_4 — at 5 temperatures (-20, -10, 0, 10, 25 °C).

BSEBench Tier-2 (harmonized)

The corresponding harmonized canonical Parquet files (BSEBench v1.1.0 schema) are at bsebench-org/panasonic-kollmeyer-2018 (Tier-2 repo). See bsebench-runner/docs/M1_HF_LAYOUT.md for the convention.

K-016 closure note

The BSEBench M1 adapter adapters/panasonic_kollmeyer_2018.py produces Tier-2 Parquet that pad cell_id and cycle_number as constant columns (single-cell driving-cycle dataset). See KAIZEN K-016 for the rationale.
