  • Publication number: 20220080844
    Abstract: A method for controlling the charging of one or more electric vehicles at one or more charging stations in a geographic locality includes determining if the charging event of an electric vehicle of the one or more electric vehicles increases a demand billing rate. The demand billing rate may be a cost per unit of energy in the locality. The method also includes charging the electric vehicle at the charging event such that the demand billing rate is not increased.

  • Patent number: 10442301
    Abstract: A method of charging an electric vehicle at a charging station includes electrically connecting the charging station to the vehicle. The charging station may be configured to charge the vehicle using a charging station charge protocol and the vehicle may be configured to receive the charge using a vehicle charge protocol. The vehicle receives a signal indicative of the charging station charge protocol and selects the vehicle charge protocol based on this signal. The vehicle is then charged using the selected vehicle charge protocol. While selecting, the vehicle may select one charge protocol from multiple charge protocols supported by the vehicle to match the charging station charge protocol.

  • Patent number: 9809122
    Abstract: A charging station for charging an electric vehicle may include a charge head movably attached to a charge head assembly and at least one head landing switch including a lever and a contact element. A first end of the lever may be rotatably coupled to the charge head and an opposite second end of the lever may be rotatably coupled to the contact element. At least a bottom surface of the contact element may be positioned below the bottom surface of the charge head such that the contact element can contact the roof of the electric vehicle before the bottom surface of the charge head can contact the roof. And, a width of the contact element may be greater than a width of the seam on the charging interface.

  • Patent number: 9321364
    Abstract: An electric bus may include a charging interface positioned on an external surface of the electric bus. One or more heating pads may be removably attached to the charging interface and configured to heat the charging interface. The heating pads may include a rigid plate forming an exposed surface of the charging interface. The plate may be positioned such that a first side of the plate forms a charging head contact surface when the charging head engages with the charging interface. A heating device may be attached to a second side of the plate opposite the first side. The heating device may include a heating element configured to heat the plate by resistive heating.
