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.
