LF Energy Battery Data Alliance Announces the Battery Data Format (BDF): A New Open Standard for Battery Data Interoperability

LF Energy, the open source foundation accelerating the energy transition, today announced that its Battery Data Alliance (BDA) project has released the Battery Data Format (BDF), an open, community-driven standard designed to bring order, interoperability, and transparency to the rapidly growing world of battery data. BDF defines a consistent structure for experimental, simulation, and metadata-rich battery datasets making it easier for researchers, industry, and software developers to collaborate and build next-generation tools.

  • Announcement: LF Energy’s Battery Data Alliance released the Battery Data Format (BDF), an open, community-driven standard for battery data interoperability.

  • Purpose: BDF provides a unified, machine-readable schema and ontology-aligned metadata to make battery data shareable, reproducible, and model-ready across labs, vendors, and software.

  • Ecosystem & Validation: Aligned with BattINFO; validated via Faraday Institution tooling (PyProBE/BDX); compatible with PyBaMM and BattMo; supported by open-source libraries and converters.

  • Adoption & Impact: Backed by major contributions (Microsoft dataset, Ohm converter, largest open BDF dataset from European research labs) and governed openly under LF Energy.
