Facilities

NREL's EV grid integration research leverages state-of-the-art labs at the Energy Systems Integration Facility, drawing on crosscutting grid modernization and power system design capabilities in concert with world-class, high-performance computing capabilities.

NREL's nationally unique Electric Vehicle Research Infrastructure (EVRI) evaluation platform enables researchers as well as industry and utility stakeholders to study and develop optimal strategies for coordinating EVs with buildings, the grid, and other energy systems. At EVRI, researchers are developing the control strategies needed to optimize a new generation of transportation technologies within the context of the larger energy ecosystem.

Enabling the characterization and development of building-integrated extreme fast charging systems, EVRI houses flexible electrical infrastructure, including AC and DC charging with a variety of voltage systems; connection to grid and photovoltaic simulators and other distributed energy resources for grid interactivity research; real-time digital simulation (grid- and vehicle-side); and diverse charging and energy storage equipment, including two 350-kW chargers (with two more expected soon), four level-2 chargers, a 50-kW charger, and a 40-kWh battery energy storage system.
