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.

Abstract: A method for charging an electric vehicle at a charging station may include electrically connecting the electric vehicle to the charging station, and determining a desired amount of energy to be provided to the electric vehicle at the charging station. The method may also include determining a layover time of the electric vehicle using a control system associated with the charging station. The layover time may be an amount of time the electric vehicle is expected to be positioned at the charging station. The method may also include calculating a charge current using the control system, wherein the charge current is a value of electric current that is needed to provide the desired amount of energy to the electric vehicle in a time period substantially equal to the layover time. The method may further include charging the electric vehicle using the calculated charge current.
