  • 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: 9987939
    Abstract: A method of docking an electric vehicle with a charging station includes periodically transmitting data from the vehicle to the charging station. The transmitted data may include a distance travelled by the vehicle location towards the charging station and its speed. An incremental distance travelled by the vehicle in a time interval between when the data is collected and received is calculated, and the distance corrected based on this calculated value. The relative position of the vehicle with respect to the charging station is determined based on the corrected distance, and a charge head of the charging station is automatically connected with the charging interface of the vehicle based on the determined relative position.

  • Patent number: 9776520
    Abstract: A method for aligning a vehicle at a charging station may include determining the distance between each sensor of the plurality of sensors and a target surface of the charging station. The method may further include aligning the vehicle at the charging station using the determined distance data, and charging the electric vehicle at the charging station. The method may further include using the determined distances to align the side of the vehicle substantially parallel to the target surface.

  • Patent number: 9315111
    Abstract: A method of charging an electric vehicle at a charging station may include driving the vehicle towards the charging station, and using a plurality of RFID tags and one or more RFID readers to determine a relative position of the charging interface of the vehicle with respect to the charge head assembly of the charging station. The method may also include engaging the charge head assembly with the charging head, and charging the vehicle.
