The invention discloses a boost charging control method, an electric driving device and a vehicle. The boost charging control method is used for improving the condition of temperature rise of the rotor of the three-phase alternating current motor during boost charging. The boost charging control method at least comprises the following steps that condition parameters are obtained, the condition parameters are associated with the duty ratio of a control signal of a power switch unit of the inverter, and the condition parameters comprise the battery voltage and the charging pile voltage; a charging mode is selected according to the condition parameters, the charging mode comprises two-phase charging and three-phase charging, in the two-phase charging, a power switch unit of the inverter is controlled to utilize a two-phase winding of the three-phase motor to carry out boost charging on the battery, and in the three-phase charging, the power switch unit of the inverter is controlled to utilize a two-phase winding of the three-phase motor to carry out boost charging on the battery. Controlling a power switch unit of the inverter to boost and charge the battery by using a three-phase winding of the three-phase motor; and controlling charging according to the charging mode.
