Adapting charging of electrical vehicles to real-time grid conditions could save utilities up to $30 billion annually and reduce peak energy demand, according to a new report by The Brattle Group and smart charging provider ev.energy.

Vehicle-to-grid integration is about more than connecting electric vehicles to the grid, say reports from DOE and the Alliance for Automotive Innovation.

DOE initiatives aimed at expanding EV charging networks have become more urgent as the November election looms and growth in EV sales has slowed.
