Its primary objective is to enable the creation of linked and FAIR (Findable, Accessible, Interoperable, and Reusable) data, thereby fostering advancements in research and innovation within the realm of batteries. This ontology serves as a foundational resource for harmonizing battery knowledge representation, enhancing data interoperability, and accelerating progress in battery research and development." ;

It is a specialized framework designed to represent and organize knowledge about battery quantities. It is designed to integrate with the battery domain ontology or other ontologies from the EMMO ecosystem. The main focus of this ontology is to provide machine-readable descriptions of common battery quantities, linking both to the larger descriptions of physical quantities in EMMO as well as other sources of information like the IEC, QUDT, Wikidata, etc. It should be used to support linked data generation in the battery domain."@en ;
