Abstract

The embodiments of the present invention provide a method for predicting average energy consumption of electric vehicles and a device for predicting average energy consumption of electric vehicles, which relate to the technical field of electric vehicles. The method includes: according to the real-time voltage and real-time current of the battery pack of the electric vehicle, determining the actual energy consumption of the traveled mileage segment corresponding to the current moment of the electric vehicle, where the traveled mileage segment includes a plurality of unit mileage segments; The actual energy consumption per unit mileage segment determines the initial average energy consumption of electric vehicles at the current moment; obtains the target average energy consumption and average energy consumption adjustment parameters of electric vehicles; adjusts according to the initial average energy consumption, target average energy consumption, and average energy consumption parameter to determine the actual average energy consumption of electric vehicles at the current moment. The invention can accurately calculate the actual average energy consumption of the electric vehicle at the current moment 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...
