A charging scheduling system and method based on electric vehicle charging priority

Abstract

The invention discloses a charging scheduling system and method based on electric vehicle charging priority. The system includes a sub-node device and an anchor node device. The sub-node device is installed at the charging pile of the sub-node for collecting data of the charging pile; the anchor node The device is installed at the anchor node charging pile for data integration and processing, executing charging scheduling algorithms, processing user feedback information, and performing charging scheduling. The invention performs area division according to the position of the anchor node, and one anchor node manages several sub-nodes, thereby improving the efficiency of data collection and calculation. The charging scheduling algorithm used performs two charging priority evaluations based on the information of electric vehicles and charging piles, and makes a global comparison of the final priority evaluation values ​​to determine the relative priority of electric vehicles at each accessible charging pile. A global solution is achieved. The invention improves the utilization rate of charging pile resources and the charging efficiency of the electric vehicle, and improves the performance of the charging system of the electric vehicle.

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...
