Knowing that an appropriate electrical power infrastructure is necessary for the success of its Chevrolet Volt, General Motors Corp. announced Feb. 3 that it will work with communities around the country to ensure that there will be plenty of charging stations for its plug-in hybrid vehicle when it goes to market next year. The company said it will concentrate its efforts on cities, including Washington and San Francisco, that already have high interest in plug-ins. GM noted that San Francisco and neighboring San Jose and Oakland all have announced plans to have in place a plug-in infrastructure by the time the Volt arrives. The company is working with the Electric Power Research Institute and a coalition of more than 40 utilities to accelerate the commercialization of plug-ins. It also is working with SAE International on development of standards for the vehicle-charging interface.
