Electric Vehicle Fueling Standards

The development of electric vehicle fueling standards is essential for ensuring the efficient and safe operation of electric vehicle charging infrastructure. The U.S. National Work Group on Measuring Systems plays a key role in proposing requirements for commercial electricity-measuring devices. The group focuses on traceable measurements to SI standards, reviewing and proposing changes to draft requirements for equipment.

Discussions within the group revolve around method-of-sale requirements and measurement traceability. In 2016, a new project was approved for revising Recommendation 46 on electrical energy meters. Additionally, a separate project group was established in 2021 specifically for electric vehicle charging stations.

The OIML Guide 22 on Electrical Vehicle Supply Equipment was published in September 2022, marking an important milestone in this area. Ongoing discussions are in progress for further revisions to develop a full Recommendation document.

Metrology and Weights Development

Developments in metrology and weights measures are essential for guaranteeing the accuracy and reliability of electric vehicle charging infrastructure. This was exemplified by the recent TC 12 p3 meeting in Delft, the Netherlands, where OIML G 22 focused on developing a First Committee Draft Recommendation.

This meeting marked a notable milestone in the development of standards for electric vehicle charging stations. The Delft meeting highlighted the necessity for software revision to ensure seamless integration with existing infrastructure.

The outcome of the OIML G 22 meeting will have a substantial impact on the development of accurate and reliable electric vehicle charging infrastructure. As the industry progresses, metrology and weights measures will play a crucial role in ensuring the reliability and accuracy of electric vehicle charging stations.

Resource Platforms for EV Innovations

In the pursuit of fostering electric vehicle (EV) innovations, several resource platforms have emerged as crucial hubs for accessing essential information, facilitating collaboration, and driving progress in the EV ecosystem.

These platforms provide a foundation for government collaboration, scientific research, and knowledge sharing. For instance, Commerce.gov offers insights into commerce-related matters and economic trends, while Science.gov serves as a portal for scientific information and research resources. USA.gov and Vote.gov provide access to government services, federal agencies, and voter information.

These resource platforms facilitate the development of EV standards, enabling stakeholders to leverage expertise, share knowledge, and advance the EV industry. By leveraging these platforms, the EV community can accelerate innovation, improve efficiency, and promote sustainable transportation solutions.

EVSE Test Instrumentation Guidance

To guarantee the accurate measurement of DC electrical quantities in electric vehicle supply equipment (EVSE), the National Institute of Standards and Technology (NIST) Office of Weights and Measures (OWM) is developing a guideline document that outlines methods for establishing traceability to primary SI standards.

This document will provide guidance on evaluating EVSEs using existing test instrumentation, focusing on methods for achieving traceability to primary SI standards. The guideline aims to secure accurate measurements by outlining methods for using commercially available test instrumentation.
