The invention discloses a charge control method and a charge control system for an electric transportation tool on a three-in-one electronic rod. The method comprises the following steps: activating acharge control unit on an energy pickup device through an intelligent center control unit on the electric transportation tool and sending a charge mode selecting command to the charge control unit; controlling the electric transportation tool to enter a corresponding charge mode by the charge control unit according to the received charge mode selecting command; and charging the electric transportation tool based on a charge flow corresponding to the charge mode, wherein different charge modes of the electric transportation tool can be switched. By means of the scheme provide by the invention,various charge modes can be fused on the electric transportation tool, and the electric transportation tool not only can be charged dynamically to enhance the cruising ability, but also can be charged statically to store energy, so that the demand on future development of the electric transportation tool is further met.
