Codes and Standards Development

Argonne researchers are helping create codes and standards that will enable widespread adoption of electric-drive transportation with smart grid interoperability. For example, the Society of Automotive Engineers' (SAE) J1772 connection standard will enable manufacturers to build compatible connector plugs and vehicle sockets that support both charging and two-way communication with utility companies. Another standard, SAE J2847, will specify the communications systems between electric vehicles and utility companies. Engineers are also actively pursuing the development of standards related to plug-in vehicles and methods to test them.

Smart Grid Metrology

Smart grid metrology systems are end-use measurement devices (EUMD) that measure and communicate energy usage information to ensure accurate consumption readings and fair billing. Argonne researchers have made a major breakthrough with the development of a compact metrology system that is a fraction of the size and cost of existing systems. The groundbreaking technology is garnering international attention due its low price of less than $30 per unit and its compact size (smaller than a business card). This technology would also be an alternative to installing a secondary charging meter specifically for charging an electric vehicle.

Software-Defined Radio

This wireless technology, which allows one radio to use different frequencies depending on needs at the time, will provide more bandwidth for electric utilities to communicate with consumer vehicles. Argonne researchers have developed a software-defined radio technology in a low-cost field programmable gate array (FPGA) device that would enable electric vehicle-to-grid interoperability for a wide variety of infrastructure resources. This promising technology offers a less expensive and more efficient option for smart grid communications.
