A boost charging control method is disclosed to improve a large rotor temperature rise of a three-phase alternating current motor during boost charging. The method includes obtaining a condition parameter being associated with a duty cycle of a control signal of a power switch unit of the inverter, and the condition parameter including a battery voltage and a charging pile voltage, selecting a charging mode based on the condition parameter, where the charging mode includes two-phase charging and three-phase charging, wherein in the two-phase charging, the power switch unit of the inverter is controlled such that two phase windings of the three-phase motor are used for boost charging of the battery, and in the three-phase charging, the power switch unit of the inverter is controlled such that three phase windings of the three-phase motor are used for boost charging of the battery, and controlling charging based on the charging mode.
