The Problem

Battery data comes from everywhere — test equipment, published research, battery management systems, field deployments, simulators — and none of it is in the same format. Teams spend more time wrangling files than learning from them.

Our Projects

Open Source Tools & Standards

Open-source standards and software that give battery data a common format — no matter where it comes from.

Battery Data Format

BDF is the open standard for battery data. One format that works across all sources, all tools, all teams.

  • Simple structure with just 3 required fields, 4 recommended
  • Compact file format (Parquet) for fast analysis of large datasets
  • Python package with converters for 8+ cycler formats
terminal
$pip install batterydf
import bdf
# Read any format — auto-detected
df = bdf.read("my_data.bdf.csv")
# Validate, clean, plot
bdf.validate(df)
df = bdf.clean(df)
bdf.plot(df)

Get Involved

BDA is built by its community. There are many ways to contribute — not just code.

Share Data

Contribute test datasets — raw data, curated benchmarks, or experiment records. Open or controlled access.

Contribute Software

Help improve batterydf, cycler control libraries, or donate your own open-source battery tools.

Donate Hardware

Contribute battery test equipment so the community can develop and test against more cycler brands.

Join the Community

Participate in discussions, attend working groups, and help shape the direction of battery data standards.

Help us build a common language for battery data

BDA is an open community — researchers, engineers, and organizations working together through Linux Foundation Energy.
