The standard defines the battery parameters, equations using them, and the reporting of experimental measurements used to validate the reported parameters.
Faraday said physics-based battery models can deliver accuracy and insight into long-term performance in a wide range of scenarios. But the complexity of physics-based models and lack of a common definition has limited their use to specialist teams within large companies, each having their own model.
The purpose of BPX is to reduce costs and time-to-market through common battery model definitions, it added.
Professor Gregory Offer of Imperial College London, said: “Design of an optimal battery system for a particular application demands a deep understanding of battery performance under a wide range of conditions. The physics-based model codified in the BPX standard makes that knowledge and understanding more available for engineers to solve real world problems. Making that knowledge widely available is a powerful enabler for the optimisation of lithium-ion technology and its successors.”
