US government to establish 48 EV charging corridors across nation
The Obama Administration will create 48 electric vehicle (EV) charging corridors along highways that cross 35 states, one of several new measures aimed at "stimulating and speeding up the deployment of zero-emission EVs in the US". The White House also said it would partner with "24 state and local governments" to get more plug-in EVs into fleets, and two Department of Energy studies have been launched to "determine optimal scenarios" for a national EV charging infrastructure.
The White House today announced a range of actions intended to stimulate and speed up the deployment of zero-emission electric vehicles in the U.S.

It took these actions, it said, as part of its efforts to "combat climate change, increase access to clean-energy technologies, and reduce our dependence on oil."

Today's announcements are part of "a continued partnership between the Administration, states, localities, and the private sector" to achieve "shared goals" of electric-car deployment.

In a statement issued this morning, the Obama Administration listed several new and expanded efforts and programs:

The U.S. Department of Transportation will establish 48 electric-vehicle charging corridors along national highways that cross 35 states and cover almost 25,000 miles

A total of 28 states, electric utilities, carmakers, and other organizations have committed to accelerate charging infrastructure along these corridors

The Administration will partner with 24 state and local governments to add more plug-in electric vehicles to their fleets

Two separate Department of Energy studies are underway to determine optimal scenarios for deploying national electric-car charging infrastructure

The existing DoE Workplace Charging Challenge has gained 38 new members, among them businesses, universities, electric utilities, and nonprofit organizations

The electric-vehicle charging corridors may be the most interesting development among this list.

The DoT's Federal Highway Administration today announced 55 Interstate highways that will be "alternative-fuel corridors," of which 48 will be designated electric-car corridors.

Existing or planned charging stations—presumably DC fast-charging for long trips—will be spaced at least every 50 miles.

And the states through which they pass will get access to standardized "signs developed by FHWA 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."

How these efforts play out in practice, of course, will become more clear over the years to come.

But with Volkswagen having agreed to spend $2 billion over 10 years to assist deployment of zero-emission vehicle charging and fueling infrastructure, there's been much discussion over where and how that money will be spent.

The designation of federal EV corridors is likely to focus much of that effort, at least in DC fast-charging, along a common set of known routes.
