  • Patent number: 9718367
    Abstract: A vehicle charging system comprises a plurality of retractable conductor bars in a housing of a vehicle. The plurality of conductor bars includes a positive conductor bar and a negative conductor bar. Individual conductor bars of the plurality are electrically isolated from one another. The vehicle charging system further comprises a charging system having a receiver mounted on a support structure. The receiver comprises a plurality of electrical contact members in electrical communication with a power source. The receiver is configured to bring individual conductor bars of the plurality in contact with the electrical contact members for charging an energy storage device of the vehicle.

  • Publication number: 20150069970
    Abstract: Systems and methods for charging electric vehicles are provided. A method for charging electric vehicles comprises providing a charging station that is electrically coupled to a power grid and an energy storage system, and alternately and sequentially charging electric vehicles using the charging station. The charging station can be configured to charge electric vehicles in succession from power supplied by the energy storage system and the power grid. The power grid can supply substantially constant power to the charging station during electric vehicle charging. The substantially constant power can be less than a power requirement of a given electric vehicle.
