Staff Sgt Rey Sedantes (left), receives instruction on how to operate the Princeton bidirectional electric vehicle charging stations from vehicle operations contractor, Oscar Machado, right, during a training demo Oct. 31, 2014, in El Segundo, Calif. The charging stations will charge the electric vehicles directly from the local utility grid enabling Los Angeles Air Force Base personnel to utilize the electric vehicles as transportation within the base. When called-upon, and when connected to the electric vehicle, the bidirectional charging station will switch power flow directions in order to support vehicle-to-grid energy request by discharging the electric vehicle's onboard battery. Sedantes is with the 61st Civil Engineering and Logistics Squadron. (U.S. Air Force photo/Sarah Corrice)
