The Obama Administration has announced more details about the national electric charging corridor, a program designed to accelerate the adoption of electric cars by expanding the charging infrastructure. We now know the Department of Transportation will create 48 charging corridors running along 55 interstate highways.

When it's fully established, the Department of Transport is hoping its expanded charging infrastructure will cover almost 25,000 miles (about 40,200 km) of highway. The plan calls for charging stations every 50 miles (80 km) along the corridors. Those stations will be identified by standard Federal Highway Administration signs, just like gas stations and rest stops.

Although this push toward electric power is being driven by the Federal Government, it's backed up by a growing list of companies. Along with Nissan and Tesla, who currently provide most of America's charging stations, the list of companies to get involved includes BMW, General Motors, General Electric and Texas-New Mexico Power.

Along with the electric charging corridor, the push to get people behind the wheel of electric cars has extended to state government fleets. Twenty-four state and local governments have committed to the electrification of their fleets, which will bring about around 2,500 new electric car purchases in 2017 alone.
