Why engineers buy it
Benchmarking a pack design means knowing what the market has actually achieved, not what is claimed in press releases. This database is sourced from datasheets, EPA applications, OEM technical documents, and regulatory filings, then cross-referenced and version-tracked. It covers:
- Trend analysis — how pack energy density, voltage architecture, and chemistry mix have evolved year on year
- Competitive benchmarking — compare your target spec against real-world production packs by application, chemistry, or voltage class
- Cell-to-pack context — each pack entry links to its cell where data is available, so you can evaluate cell selection decisions across the industry
- BESS coverage — home, commercial, grid, UPS, and telecom storage systems alongside EV packs, all in one file
- Design data — pack dimensions, mass, cooling type, and configuration alongside electrical parameters
| Version 1.8.01 — updated September 2026. More Commercial Vehicle battery packs covered in the database and a thorough cross-check of everything with move to 1.8+. This database is part of the All Access Pass. |
What the data shows
BEV road car pack energy — median usable kWh by launch year
Based on packs with confirmed usable energy data. 2025 figures are lower than 2024 because many 2025 entries do not yet have confirmed energy values, which suppresses the median.
Cell chemistry — BEV road cars (506 entries with identified chemistry)
Gravimetric pack energy density — median Wh/kg by launch year (BEV road cars)
