Abstract: The embodiments of the present application provide a method and an apparatus for predicting an average energy consumption of an electric vehicle. The method comprises: according to a real-time voltage and a real-time current of a battery pack of an electric vehicle, determining an actual energy consumption of the electric vehicle in the traveled mileage segment corresponding to the current time, the traveled mileage segment comprising a plurality of unit mileage segments; according to the actual energy consumption of each unit mileage segment of the traveled mileage segment, determining an initial average energy consumption of the electric vehicle at the current time; acquiring a target average energy consumption and average energy consumption adjustment parameters of the electric vehicle; and according to the initial average energy consumption, the target average energy consumption and the average energy consumption adjustment parameters, determining the actual average energy consumption of the electric vehicle at the current time. The present application can accurately calculate the actual average energy consumption of the electric vehicle at the current time in real time.
