Abstract
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.
