An update to proposed standards for electric vehicles set by the American National Standards Institute has identified eight new standardization “gaps” where it says new or revised regulations would prove useful.
Standardization Roadmap for Electric Vehicles – Version 2.0, identifies standardization gaps covering electromagnetic compatibility issues related to electric vehicle charging; the functionality and measurement characteristics of electric vehicle sub-meters including those embedded in charging stations or electric vehicles; coordination of electric vehicle sub-metering activities; cybersecurity and data privacy; telematics smart grid communications; electrical energy stranded in an inoperable rechargeable energy storage system; and workforce training related to charging station permitting and college and university programs.
In this context, a gap refers to a “significant” issue – whether it be related to safety, performance, interoperability or something else – that has been identified and that should be addressed in a standard, code, regulation or conformance program, the report says. Gaps can be filled through the creation of entirely new standards, code provisions, regulations, or through revisions to existing ones, ANSI says.
Version 2.0 also highlights the closing of four partial gaps on power quality, DC charging levels, the safety of electric vehicle supply equipment, and electric vehicle coupler safety, where work to publish a new standard or a revision to an existing standard was still in progress at the time the original roadmap was released last year and has now been completed. Presently, the roadmap has identified a total of 44 gaps or partial gaps.
Developed by representatives from more than 100 private- and public-sector organizations, the Standardization Roadmap aims to catalyse coordination between those developing standards for electric vehicles and the charging infrastructure needed to support them. The publication considers issues that are integral to consumer adoption of electric vehicles such as safety, performance, and interoperability. It describes relevant standards, codes and regulations that already exist or that are in development, as well as gaps where new or revised standards would prove useful.
Version 1.0 of the standards was released in April 2012. Members of the automotive, electrotechnical and utilities industries and other standards developing organizations and government contributed to the roadmap.
