The invention discloses a system and method for calculating instantaneous power consumption of a pure electric vehicle, and belongs to the technical field of pure electric vehicles. The method comprises the steps that S1, the vehicle is ready; s2, the vehicle control unit obtains the voltage and current of the vehicle power battery and calculates the discharge power of the vehicle power battery; s3, the vehicle control unit obtains the voltage and the current of the accessory module and calculates the discharge power of the accessory module; s4, the vehicle control unit judges whether the vehicle speed is larger than a preset speed threshold value or not, if yes, the step S5 is executed, and if not, the step S7 is executed; s5, the vehicle control unit calculates the discharge power generated in the vehicle driving process; s6, the vehicle control unit calculates instantaneous power consumption generated in the vehicle driving process; and S7, ending. By means of the system and method for calculating the instantaneous power consumption of the pure electric vehicle, the instantaneous power consumption generated in the running process of the pure electric vehicle can be accurately obtained.
