T he IEEE Standards Association (IEEE-SA) recently signed a memorandum of understanding with the Society of Automotive Engineers International to collaborate on vehicle-electrification standards related to the smart grid.
As more plug-in EVs are added to the grid, more power will be needed at peak times—which will require an expanded infrastructure. That calls for closer collaboration between the two organizations to develop standards supporting plug-in electric and hybrid vehicles and their power requirements and enabling vehicle-to-grid communications.
SAE International, whose standards focus on the vehicle, currently has 46 related to electric vehicles, with more than 30 new ones in the works. IEEE-SA has more than 100 standards relevant to the smart grid, with others in the planning stages.
Standards developed by SAE and IEEE-SA will spell out how vehicles can be charged at off-peak hours and help utilities better manage the grid during peak hours, thus minimizing cost and impact to the grid.
Under terms of the agreement, each organization will share its relevant draft standards with the other.
Here are a few of the applicable IEEE standards:
The IEEE Guide for Electric-Sourced Transportation Infrastructure provides guidelines that can be used by utilities, manufacturers, transportation providers, infrastructure developers, and even those who drive EVs to develop and support systems that allow increased use of electric and hybrid vehicles.
To reduce the amount of new power that has to be generated and better use existing power, the document outlines efficient methods for electric transportation based on an end-to-end systems approach. It also includes standards that have already been approved, as well as openings where new standards are needed, and describes research that is presently under way.
The document is designed to help utilities plan the most economical ways to support increasing transportation loads. It provides terminology for methods and equipment and planning requirements for EV transportation, including its impact on systems for generating, transmitting, and distributing electric power.
The IEEE Standard for Broadband Over Power Lines specifies the sophisticated modulation techniques required for transmitting data over standard AC power lines of any voltage at transmission frequencies of less than 100 megahertz. The specifications address a wide range of applications, including smart energy, transportation, and local area networks (LANs).
In the transportation sector, for example, the standard spells out what’s needed to deliver audiovisual entertainment to the seats of airplanes, trains, and other forms of mass transit. It also describes how EVs can download new entertainment playlists while their batteries charge overnight. Networking products complying with IEEE 1901 will deliver data rates in excess of 500 megabits per second in LAN applications. In first-mile/last-mile applications, such devices will achieve ranges of up to 1500 meters.
IEEE 1547 Series
Known as the Standards for Interconnecting Distributed Resources with Electric Power Systems, this series highlights interconnections that include both distributed generators and energy storage systems. The series establishes requirements and provides a standard for interconnecting distributed resources with electric power systems and electric and hybrid vehicles. It also includes requirements relevant to the performance, operation, testing, safety, and maintenance of the interconnection.
