Electric vehicle charging station planning method and system

Abstract

The invention relates to an electric vehicle charging station planning method and system. The method comprises steps: the city is divided into regions with equal side lengths; the traffic index of each region is determined according to vehicle GPS trajectory data of each region and UGC departure and destination data, and the traffic index of each region is subjected to normalization processing; according to the number of charging stations in each region and the utilization rate of a charging pile in a charging station, the utilization rate index of a charging facility in each region is determined; according to the traffic index of each region after normalization processing and the traffic index of each region, a charging station construction demand index in each region is determined; and according to the charging station construction demand index in each region, a charging pile mounting region is selected. According to the technical scheme provided in the invention, analysis is carriedout based on the regional traffic index and the existing charging station utilization rate condition, a scientific and reasonable optimal site selection result is obtained, and the charging experience of an electric vehicle user is enhanced.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a method and system for planning an electric vehicle charging station. Background technique [0002] Electric vehicles have the advantages of alleviating environmental pollution and improving the structure of the automobile industry. Therefore, they have received strong support from the state and have broad development prospects. In recent years, with the rapid development of electric vehicles in my country, as the charging system for electric vehicle infrastructure, the reasonable location of charging stations has affected the utilization rate of charging stations. [0003] At present, different theories and algorithms are used in the planning of electric vehicle charging stations, such as queuing theory, particle swarm algorithm, genetic algorithm, etc., mainly considering the investment cost of the charging station, ignoring the utilization rate of the charging station...
