Abstract

The embodiment of the invention provides an electric vehicle average energy consumption prediction method and an electric vehicle average energy consumption prediction device, which relate to the technical field of electric vehicles. The method comprises the steps that according to the real-time voltage and the real-time current of a battery pack of the electric vehicle, the actual energy consumption of a traveled mileage segment corresponding to the current moment of the electric vehicle is determined, and the traveled mileage segment comprises a plurality of unit mileage segments; according to the actual energy consumption of each unit mileage section of the traveled mileage section, the initial average energy consumption of the electric vehicle at the current moment is determined; target average energy consumption and average energy consumption adjustment parameters of the electric vehicle are obtained; and according to the initial average energy consumption, the target average energy consumption and the average energy consumption adjustment parameters, the actual average energy consumption of the electric vehicle at the current moment is determined. Thus, the actual average energy consumption of the electric vehicle at the current moment can be accurately calculated in real time.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for predicting average energy consumption of electric vehicles and a device for predicting average energy consumption of electric vehicles. Background technique [0002] The real-time display of the energy consumption of electric vehicles not only allows users to more intuitively feel the energy consumption per 100 kilometers of electric vehicles, but also provides a guarantee for users in the process of using the car. The current calculation of energy consumption of electric vehicles is usually obtained from the total discharge power and total mileage of the entire power-on cycle, which cannot reflect the driver's driving habits or the impact of real-time working conditions on energy consumption in real time during driving. Therefore, it is impossible Accurately calculate the current energy consumption of electric vehicles. Contents of the invention [0003...
