Abstract

The invention proposes a charging pile setting method for dividing regions based on driving data and a Voronoi diagram, and belongs to the field of electric car. The method comprises the steps: firstly carrying out the dividing of a region where charging piles need to be set into subregions through a Voronoi diagram method; calculating the maximum charging load of each subregion through the driving data, and selecting the maximum value and the subregion corresponding to the maximum value; building a value model for the selected subregion, solving the model through a particle swarm algorithm, obtaining the positions of added charging piles in the subregion and an optimization result of the number of the charging piles; adding the added charging piles to a map of the region, carrying out thenew subregion dividing of all charging piles and the optimization calculation of a charging station till the constraint condition exceeds a preset upper limit, and ending the setting of the chargingpiles in the region. According to the invention, the method takes the obtaining of the high-efficiency charging of an electric car and the reduction of the construction cost of the charging facility as the objectives, achieves the reasonable site selection and capacity fixing for the setting of the charging piles through the driving data of the car, and is very high in globality and accuracy.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a charging pile setting method based on driving data and Voronoi diagram division areas. Background technique [0002] Compared with traditional vehicles, electric vehicles have the advantages of no pollution, high energy efficiency, simple structure, and low noise. From the perspective of coping with energy structure adjustment, environmental protection, and cultivating future technological competitive advantages, the development trend of electric vehicles is inevitable. With the steady growth of the number of electric vehicles, there have been some problems that inhibit the development of electric vehicles. Among them, the unreasonable distribution of charging piles and the low utilization rate bear the brunt, which seriously restricts the popularization and promotion of electric vehicles. [0003] In order to solve this problem, scholars at home and abroad have co...
