1. A structure comprising:
- an alignment mechanism used to align an electric vehicle in a parking lane of an electric vehicle charging station;
a coupler assembly comprising an arm and a charging coupler located in the parking lane and positioned beneath the electric vehicle, the charging coupler is positioned at one end of the arm, and is moveable in a vertical direction relative to the parking lane, and a second end of the arm is pivotally mounted in the parking lane, wherein the charging coupler is movable in a vertical arc pivoting from the second end of the arm, wherein the charging coupler comprises three electrical contacts each in a shape of a right conical frustum extending from the charging coupler in the vertical direction, wherein each of the electrical contacts partially overlaps a protrusion mount, an insulator surrounding the protrusion mount, and a tension spring surrounding the insulator, wherein the protrusion mount, the insulator and the tension spring are mounted on a charging coupler housing;
a cleaning device for cleaning the charging coupler and a receptacle of a battery in the electric vehicle; and
an electromagnetic sensor used to detect a presence of the electric vehicle in the parking lane, to automatically physically and electrically connect the coupler assembly to the receptacle and to charge the battery,wherein the receptacle comprises a receptacle housing with three cone shaped receptacle wells with a corresponding receptacle contact in each of the receptacle wells, wherein the three receptacle wells are sized and shaped such that the receptacle wells align with the three electrical contacts and when the receptacle is inserted in the charging coupler, the three electrical contacts are electrically connected to a corresponding receptacle contact;
wherein the charger coupler comprises a replaceable charging coupler for a worn out charging coupler, and the receptacle housing comprises a replaceable receptacle housing for a worn out receptacle housing.
