The invention belongs to the technical field of power electronics, and particularly relates to a charging current control method and device, a charging method, a medium and a controller. The first working condition simulation step/unit simulates and/or excites a motor (999) with preset data to obtain a working point sequence of a charging current (062) corresponding to a preset working condition sequence under the action of a compensation current vector (069), and obtains a numerical solution set corresponding to value distribution of an electromagnetic torque (060); a second model reconstruction step/unit obtains first current distribution data (077) of a compensation current vector (069) based on a numerical solution set according to an electromagnetic relationship between the charging current (062) and the compensation current vector (069) and a rotor position electrical angle (064) in a charger mode; and the third torque compensation step/unit inhibits the torque pulsation of the ripple current vector (080) according to the corresponding relation of the ripple current vector (080) under the reconstruction model, and can replace an experimental calibration method to be applied to zero torque control ZTC (Zero Torque Control) of various types of motors (999) and optimize winding loss.
