DOE-JRC Letter of Intent

11

• Establish Electric Vehicle / Smart Grid Interoperability Centres, at Argonne National Laboratory in the United States and JRC-Ispra, in Italy

• State-of-the-art facilities for development and testing of vehicle-grid interface technologies – encompassing connectivity between electric vehicles, charging equipment, communication networks, electric transmission and distribution grid operators, and energy service providers;

• Active role in standardization; supporting data-driven standards refinement and development, a common approach between EU and US testing of electric vehicle and smart grid equipment, all in an effort to promote cooperative development of and support for global standards;

• Projects to enhance interoperability of electric vehicles, recharging systems and smart grids through, among other things, the development of more harmonized standards for connectivity, communication and component compatibility.

• Inter-laboratory comparisons through ‘round robin’ testing
