The United State Department of Transportation (DOT) has unveiled plans to establish 48 national electric vehicle charging corridors on highways, covering nearly 25,000 miles in 35 states.

Almost 30 organisations have committed to accelerating the deployment of electric vehicle charging infrastructure.

55 Interstates will serve as the basis for a national network of ‘alternative fuel’ corridors spanning 35 states plus the District of Columbia, including the 48 designated electric vehicle charging corridors.

To make it easier for drivers to identify and locate charging stations, states designated as ‘sign-ready’ are authorised to use signs that identify electric vehicle charging stations and other alternative fuels along the highways similar to existing signage that alerts drivers to gas stations, food, and lodging. Drivers can expect either existing or planned charging stations within every 50 miles.

Almost 30 organisations have committed to accelerating the deployment of electric vehicle charging infrastructure along the Alternative Fuel Corridors, including BMW, ChargePoint, EV Connect, General Motors, Nissan, Pacific Gas & Electric (PG&E), Southern California Edison and Texas-New Mexico Power.

Early next year, two studies will be published; the first is a national EV infrastructure analysis that identifies the optimal number of charging stations for different EV market penetration scenarios. The second will provide best practices for EV fast charging installation, including system specifications as well as siting, power availability, and capital and maintenance cost considerations.
