Abstract

The present invention discloses a planning method of an electric vehicle fast-charging station on an expressway. The planning method comprises: step 1, predicting spatial-temporal distribution of a charging load of an electric vehicle, that is, determining a position and a time for charging each electric vehicle on the expressway; step 2, determining an address of the fast-charging station by using a shared type nearest neighbor clustering algorithm according to a prediction result of the spatial-temporal distribution of the charging load of the electric vehicle; and step 3, determining a quantity C of chargers in the fast-charging station by using a queuing theory according to the prediction result of the spacial-temporal distribution of the charging load of the electric vehicle and the determined address of the fast-charging station. Because of battery characteristics, a gasoline station of a traditional vehicle does not perfectly fit the fast-charging station. In the planning method, locating and sizing is performed by considering the position and the time for charging the electric vehicle, and compared with a position of a traditional gasoline station, the position of the fast-charging station can greatly meet a charging requirement of the electric vehicle, thereby promoting development of the electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of fast charging station planning for electric vehicles, and relates to a planning method for selecting locations and determining capacity based on information such as traffic network, electric vehicle related characteristics, and user travel behavior. Background technique [0002] So far, the research on charging station planning is still relatively preliminary, and a complete and systematic charging station planning model and method have not yet been formed. Most of the existing literature on site selection and capacity determination roughly estimates the number of charging stations based on the cruising range of electric vehicles and the traffic network, or selects the site and capacity based on traffic network traffic. However, due to the characteristics of electric vehicles, electric vehicle fast charging stations and gas stations may not exactly match. Contents of the invention [0003] Aiming at th...
