Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have released a technical report that could help improve the performance of electric vehicles (EVs) and the efficiency of the electric utility grids that power them.
The report documents a series of test procedures designed to enable engineers, designers and utilities to evaluate the performance of various EVs and hybrids to optimize how they connect with electric utility grids today – and “smart grids” in the future. As more vehicles with large batteries come into use and smart grid technology advances, grid operators in the future may be able to take advantage of the two-way flow of power from EVs and hybrids plugged into utility grids to smooth spikes in demand and improve the reliability of their systems. Evaluating today’s vehicle technologies will advance the goal of transforming the nation’s transportation system to maximize efficiency and use of clean energy.
