EetT

EetT is a term used in academic and policy contexts to designate a proposed framework for evaluating and guiding electric and autonomous transport technologies. Rather than a single product, EetT represents a family of interoperable standards, guidelines, and assessment methods intended to harmonize vehicle platforms, charging and energy systems, and data sharing practices across different jurisdictions.

The concept emerged in 2022–2023 from a collaboration among universities, research institutes, and transportation authorities. It seeks to address interoperability between electric vehicles, charging networks, public transit, and associated software ecosystems by providing a common set of criteria and test protocols.

The framework includes several core components. It outlines performance metrics for energy efficiency, reliability, safety, and lifecycle impact; provides data interoperability and privacy guidelines to enable secure information exchange among vehicles, infrastructure, and mobile applications; offers an accreditation pathway with certification levels for products and services; and specifies governance arrangements to coordinate updates, versioning, and stakeholder participation.

In practice, municipal agencies and researchers have used EetT as a planning and procurement lens in pilot projects evaluating new charging strategies, fleet electrification, and autonomous shuttle deployments. Proponents cite clearer benchmarks and procurement efficiency, while critics note the risk of slow adoption, cost, and potential fragmentation if multiple regions diverge from a common baseline.

As a conceptual framework, EetT has yet to become a formal international standard. Ongoing work focuses on aligning with existing standards for energy data models and vehicle-to-grid communication, and on building consensus among industry, regulators, and consumers.
