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.
