Electric vehicle energy consumption prediction method, system and equipment based on data driving and medium

Abstract

The invention provides an electric vehicle energy consumption prediction method, system and device based on data driving and a medium, and the method comprises the steps: collecting the operation monitoring data of a tested vehicle through the Internet of Vehicles, obtaining the historical operation data, constructing a vehicle driving time-space electric quantity relation model through the combination of a Monte Carlo method, and calculating the energy consumption of the tested vehicle; obtaining a running time-space electric quantity relation of the tested vehicle; external factors are obtained according to the historical operation data, a vehicle driving condition prediction model is constructed based on a KNN algorithm according to the external factors, and the future driving condition of the tested vehicle is predicted by obtaining the current external factors of the tested vehicle; and according to the historical operation data, constructing an energy consumption prediction model based on a machine learning algorithm, and predicting the energy consumption demand of the tested vehicle in combination with the running time-space electric quantity relationship and the future running condition of the tested vehicle. According to the method, the real-time performance of prediction data is improved, the accuracy to the tested vehicle individual can be realized, real-time data support can be provided for the travel of the user, and the mileage anxiety is relieved.

Description

technical field [0001] The present invention relates to the technical field of new energy vehicle applications, in particular to a data-driven electric vehicle energy consumption prediction method, system, device and medium. Background technique [0002] With the increasing attention of all walks of life to energy and the environment, the number of electric vehicles on the market is gradually increasing. Thanks to the country's subsidy policies, incentives for car purchases and incentives for environmental protection, the new energy vehicle industry has ushered in explosive growth, and my country has now become the world's largest pure electric vehicle market. With the continuous promotion of electric vehicles, the performance of electric vehicles has received more and more attention. Looking at the development status of electric vehicles in various countries in the world, the technical problems facing us are mainly in terms of battery performance. [0003] Due to the impa...

Problems solved by technology

[0003] Due to the impact of battery performance and charging inconvenience, users cannot meet the needs of free travel, and must plan the driving route before travel to measure whether the remaining power of the vehicle can meet the travel requirements

Because the energy consumption of electric vehicles is greatly affected by the driving road and the weather temperature, the driving range provided by the car company is often far from the actual driving range. The driving range cannot provide a good driving guidance for the driver, resulting in driving "Range Anxiety" among employees reduces people's confidence in the use of electric vehicles
