A second communication unit of a power receiving vehicle sends a charging start request signal to a power supplying vehicle located on a planned travel route of the power receiving vehicle. At least one of a first travel control unit of the power supplying vehicle and a second travel control unit of the power receiving vehicle brings the power supplying vehicle and the power receiving vehicle close to each other up to a position that satisfies a charging start condition when the first travel control unit receives the charging start request signal from the power receiving vehicle through a first communication unit of the power supplying vehicle. The remaining charge of a battery of the power receiving vehicle is managed by performing charging between the power supplying vehicle and the power receiving vehicle.
