LF Energy Releases Battery Data Format: An “Open Source” Standard for BESS Interoperability
The Battery Data Alliance launches the Battery Data Format (BDF), enabling seamless sharing and analysis of battery energy storage system (BESS) data across labs, vendors, and software platforms.

USA, California, San Francisco: LF Energy’s Battery Data Alliance (BDA) has unveiled the Battery Data Format (BDF), an open, community-driven standard designed to bring clarity, consistency, and interoperability to battery data. The new format provides a unified, machine-readable structure with metadata aligned to the BattINFO ontology, allowing datasets from experiments, simulations, and industrial projects to be easily shared, reproduced, and analysed across the battery energy storage ecosystem.
BDF has been validated using tools from the Faraday Institution, including PyProBE and BDX, and is compatible with leading battery modelling and analysis platforms such as PyBaMM and BattMo. The standard is further strengthened by major contributions from the industry, including Microsoft’s open battery dataset, Ohm’s BDF converter for cycler data, and a large 199-battery dataset created by European research labs (Empa, ETH Zurich, EPFL, SINTEF).
By standardising data formats, BDF addresses two key challenges: ensuring consistency across laboratories and vendors and making battery models easily compatible with multiple datasets. The open, extensible, and implementation-agnostic design allows BDF to adapt as new battery chemistries, devices, and data types emerge.
BDF is accompanied by Python libraries, conversion tools, and reference visualisation tools, making it straightforward for labs, researchers, and developers to adopt the standard. Its structure also supports FAIR-linked data practices, ensuring interoperability across the global battery research community.
“BDF gives the battery sector a common language for sharing and analysing data,” said Gabe Hege, Chairperson of the Battery Data Alliance. “We invite researchers, companies, and software developers to adopt and contribute to this open standard to accelerate innovation and collaboration in battery energy storage systems.”
