Battery Parameter eXchange (BPX) is an open standard for physics-based Li-ion battery models. It defines the core battery parameters, the equations that use those parameters, and the reporting of experimental measurements used to validate the reported parameters. The standard sets out a human-readable JSON schema describing the parameters which can be used for the Doyle-Fuller-Newman (DFN) model and is designed to be portable between different simulators.
DandeLiion cloud service fully supports BPX JSON-file format import and export. Test BPX DFN simulations can be submitted online on
