A charging system for an electric vehicle has an elongate enclosure having a plurality of sides and an at least partially open side. The enclosure defines a hollow interior. The charging system further includes a conductor rail disposed in the hollow interior and that is accessible through the at least partially open side of the enclosure. The conductor rail may be placed in electric communication with an electrical power source and thereby may be selectively placed in electrical communication with an electrical connector of an electric vehicle. The charging system may conduct electric current from the electrical power source to an electric power supply of the electric vehicle.

Provided is an electric vehicle in which the state of contact between an electric connection arm and an external power line can be stabilized during traveling of the electric vehicle. In the electric vehicle, when the free end of an electric connection arm contacts an external power line during traveling of the electric vehicle, a posture control device controls the posture of the vehicle body so that the rotation angle of the electric connection arm approaches a target rotation angle or a target rotation angle range.
