Embodiment Construction

[0076] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0077] The invention proposes a method for predicting the charging and swapping demand of electric vehicles, which is used to predict how many electric vehicles need to be charged or swapped in a specific time period in a target area, so as to provide a basis for centralized scheduling of charging and swapping stations. Its initial input is data such as the number of parking spaces in the target area and the average traffic flow on the road. During the actual operation, the time and geographical location of each charging / replacing demand are counted, and used as a large data set to build electric vehicle charging / replacing Demand probability d...

Abstract

The invention relates to an electric vehicle charging demand prediction method, a storage device and a system. According to the prediction method, Poisson distribution is adopted to fit the quantity of electric vehicles in a set subdivided time period in a target region according to historical statistical data of actual charging demands, and then a probability distribution model of the charging demands is constructed; and predicted values of the charging demands are calculated based on the probability distribution model of the charging demands. Through the prediction accuracy calculation method, K-L divergence is utilized to evaluate the accuracy of a prediction result, and then a confidence coefficient of charging demand prediction is obtained and applied to an actual scheduling algorithm. Through the prediction method, a car owner or a regional agent does not need to make a declaration in advance, manpower and material resources and time cost can be substantially saved, and prediction efficiency and user experience are improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method for predicting demand for charging and swapping of electric vehicles, a storage device and a system. Background technique [0002] The operational efficiency of charging / swapping facilities (charging electric vehicles or replacing power batteries) is directly related to user experience and the input, output, and economic benefits of charging / swapping facilities. The demand for charging / replacing batteries is affected by many factors, and has great randomness in time and space. If the operator of the charging / swapping facilities can accurately, reasonably and timely predict the charging / swapping needs of users, they can make reasonable scheduling and allocation of charging / swapping facilities and resources according to the needs, so as to maximize the use of charging / swapping facilities. Battery replacement facilities, and improve user experience by reducing the user's c...
