Battery Data Format
An open, tool-independent format for cell-test time series — time, voltage, current, temperature, cycle and step with agreed names and units — promoted by the Battery Data Alliance so data from different cyclers can be shared and compared without conversion scripts.
- Abbreviation
- BDF
- Also called

Example
Data, communication and electronics: an example situation
2500 in a log might mean 25.00 °C, 2.5 V or raw counts. Units and scale must accompany the value.
Read Battery Data Format alongside Battery cycler in this context. The instrument that charges and discharges cells to a programmed schedule while logging voltage, current and temperature, with one independent channel per cell. Laboratory cyclers resolve microvolts; production formation cyclers handle thousands of cells at once.
Use in Lemonergy
Separate quantities from encoding and transport.
This is a reference concept. No executable Lemonergy block has been verified for this term.
