Charging scheduling system based on electric vehicle charging priority and method thereof

Abstract

The invention discloses a charging scheduling system based on an electric vehicle charging priority and a method thereof. The system comprises a child node apparatus and an anchor node device. The sub-node apparatus is installed on a child node charging pile and is used for collecting charging pile data. The anchor node device is installed on an anchor node charging pile and is used for data integration and processing, executing a charging scheduling algorithm, processing user feedback information and carrying out charging scheduling. According to a position of an anchor node, area division is performed. One anchor node manages several child nodes. Data collection and operation efficiency are increased. By using the charging scheduling algorithm, according to information of an electric vehicle and the charging pile, charging priority degree assessments are performed twice; global comparison is performed on a final priority degree assessment value; relative priorities of the electric vehicle on each reachable charging pile are determined so that global solution is realized. By using the system and the method in the invention, a utilization rate of a charging pile resource and charging efficiency of the electric vehicle are increased; and charging system performance of the electric vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a charging scheduling system and method, in particular to a charging scheduling system and method based on electric vehicle charging priority. Background technique [0002] In recent years, with the depletion of fossil energy and serious environmental pollution, the research and development of new energy vehicles has become the only way to build a resource-saving and environment-friendly society. In this context, electric vehicles came into being. However, after years of development, electric vehicles have not yet entered thousands of households. This is because their inherent limitations have not been broken through: less energy storage, short mileage, slow charging, and need to use public charging devices for relay charging to ensure battery life. However, the current solutions to such problems are concentrated in the fields of vehicle power battery modeling and the impact o...
