A Fraunhofer study for T&E outlines the potential economic benefits of 'vehicles to grid' technology. As Europe transitions to clean energy and zero-emission transport, electric vehicles (EVs) are emerging as 'batteries on wheels' with the potential to revolutionise our energy system. A new study by the research institutes Fraunhofer ISI and ISE reveals how bidirectional charging could transform EVs into 'virtual power plants', delivering substantial economic benefits.
