During travel of the electric vehicle, the charging arm is extended in the vehicle width direction, a positive electrode overhead line of the power supply device and a positive electrode power reception unit of the charging arm are brought into contact at the same time that a negative electrode overhead line of the power supply device and a negative electrode power reception unit of the charging arm are brought into contact, and a power storage device for driving the electric vehicle is charged. A charging head that is the tip section of the charging arm is held within a V-shaped groove to which the positive electrode overhead line and the negative electrode overhead line are attached, thereby minimizing the loss of contact even if the charging arm shakes in the vertical direction as a result of the condition of the road surface, brake operation, or the like.

A power supply system comprising a track, which defines a trajectory, wherein the track comprises a track segment terminating at a segment end in a forward direction of the trajectory, and a hood, which is arranged in the extension of the track segment along the trajectory in the forward direction beyond the segment end; while a stringer, which supports the track segment, extends along the trajectory and terminates with a cut end in the forward direction. According to the invention, the system further comprises a reinforcing piece, which is applied against the cut end, in order to extend the stringer in the forward direction, wherein the reinforcing piece is essentially made of plastic and supports the hood.

A vehicle charging system which comprises a electric cord and vehicle connector assembly, a sensor for determining the thermal buildup in the electric cord and vehicle connector assembly, and the processor monitors and modifies the pilot signal so as to limit the level of current being supplied to the electric vehicle.
