New York (CNN Business) General Motors, America's largest automaker, and Bechtel, the country's largest construction company, are teaming up to build thousands of electric vehicle fast-charging stations across the United States. The two companies have agreed to create a new company that will build the charger network.

Adding more fast charging stations should provide a boost to sales of electric cars. One of the biggest concerns Americans have about electric cars is whether there will be enough places to charge them, according to a recent survey by AAA.

GM will provide the data and expertise needed to place chargers in the locations where they can best be used, the two companies said. Bechtel, meanwhile, will provide its own expertise in engineering, building and permitting for the stations.

Neither company plans to put money into this project, though. The two companies will create a separate corporation to build the charging network and other companies are being invited to invest in it. Neither GM nor Bechtel would name potential investors while discussions are still ongoing.
