Electric automobile public charging facility planning method

Abstract

The invention relates to an electric automobile public charging facility planning method, more specifically, relates to an electric automobile public charging facility planning method. According to the construction type difference and the characteristics of the electric automobile, the charging piles are divided into two types of high-power quick-charging piles and small-power slow-charging piles;the charging behavior characteristics of all types of electric automobiles are analyzed, an electric automobile charging model is adopted, the proportion of the charging time occupied by the public charging requirement and the self-charging requirement is distinguished, the total demand of all types of electric automobiles on the public charging amount is calculated, and through the combination of the charging capabilities of the quick / slow charging piles, the number of charging piles contained in an integrated charging station and the number of scattered charging piles, the total demand of an integrated city charging station and scattered public charging piles are calculated, and furthermore, the setting sites and quick / slow charging pile number of electric automobile public charging facilities are planned according to the actual construction conditions of the local public charging facilities and the principle of demand priority.

Description

technical field [0001] The present invention relates to a method for planning public charging facilities, and more particularly, to a method for planning public charging facilities for electric vehicles. Background technique [0002] With the rapid growth of the global economy, the shortage of fossil energy has gradually emerged; after the industrial revolution, the rapid development of industry and agriculture and urbanization have brought about environmental problems such as climate warming, ozone layer destruction, and air pollution. Energy: In recent years, smog has occurred frequently in many areas of the country, threatening people's health, and the pollution caused by automobile exhaust has become increasingly prominent, which has become a problem that we cannot ignore and needs to be solved urgently. Faced with the dual pressure of energy and environmental issues, electric vehicles have become one of the ways to get out of the predicament with strong support and deve...

AI Technical Summary

Problems solved by technology

[0004] Existing patents and documents mainly consider the construction method or planning method of electric vehicle charging infrastructure, such as patent CN102880921A, which is based on the Voronoi diagram for charging load distribution, and aims to optimize the investment and cost that can be affected by the location of the charging station. The construction of charging stations, but there is no detailed method for the planning and construction of public charging facilities for electric vehicles, and the impact of the difference between public charging demand and self-use charging demand for electric vehicles on planning is not considered
