Provided are a contact charging method and a contact charging system for an electric vehicle (10) in which the loss of a contact state is minimized even if the electric vehicle (10) shakes in the vertical direction (UL) when performing contact charging via a charging arm (18) of a power supply device (26) during travel. During travel of the electric vehicle (10), the charging arm (18) is extended in the vehicle width direction (WD), a positive electrode overhead line (24p) of the power supply device (26) and a positive electrode power reception unit (36p) of the charging arm (18) are brought into contact at the same time that a negative electrode overhead line (24n) of the power supply device (26) and a negative electrode power reception unit (36n) of the charging arm (18) are brought into contact, and a power storage device (100) for driving the electric vehicle (10) is charged. A charging head (34) that is the tip section of the charging arm (18) is held within a V-shaped groove (23) to which the positive electrode overhead line (24p) and the negative electrode overhead line (24n) are attached, thereby minimizing the loss of contact even if the charging arm (18) shakes in the vertical direction as a result of the condition of the road surface, brake operation, or the like.
