Data Interoperability Standards

Why Interoperability Matters

If every manufacturer creates a custom JSON schema for their passport, the data becomes useless to regulators and recyclers who must process thousands of different battery models. The regulation mandates open interoperability standards.

The Role of the Global Battery Alliance (GBA)

While the EU sets the legal requirement, technical consortiums like the GBA and standardization bodies like CENELEC are defining the actual JSON-LD schemas. These schemas ensure that a field named cycle_life means exactly the same thing, mathematically and structurally, regardless of the manufacturer.
