Researchers at the US 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 optimise how they connect with electric utility grids today - and "smart grids" in the future.
