Electric vehicle charging system and device based on mobile charging pile scheduling

Abstract

The invention belongs to the technical field of electric vehicle charging, particularly relates to an electric vehicle charging system and device based on mobile charging pile scheduling, and aims tosolve the problems that an existing mobile charging pile scheduling method is small in scheduling range, a charging vehicle cannot be found, and the electric vehicle is inconvenient to charge due to inconvenient recovery and maintenance. The system disclosed in the present invention comprises: an information interaction unit for acquiring charging request / reservation / charging completion information; a data acquisition unit used for acquiring a current charging demand, current mobile and fixed charging pile distribution diagrams and residual electric quantity information of each mobile chargingpile; a charging demand prediction unit used for predicting the charging demand of the next time period; a charging pile scheduling unit used for generating a charging demand prediction distributiondiagram and performing charging pile scheduling in combination with the data of the data acquisition unit; a charging unit used for selecting the optimal charging pile to charge the electric vehicle.According to the system, the mobile charging pile is scheduled in advance on the basis of predicting the charging demand, the charging efficiency of the electric vehicle is high, the accuracy is high,and the real-time performance is good.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to an electric vehicle charging system and device based on scheduling of mobile charging piles. Background technique [0002] Facing the background of global energy shortage, increasingly severe environmental pollution, and increasing requirements for energy conservation and emission reduction, new energy vehicles have been developed in large numbers. In recent years, the number of new energy electric vehicles in my country has been increasing. When the urban charging pile reaches a certain order of magnitude, its overall impact on the power grid is huge. In particular, there is a certain law in the charging of electric vehicles, which is concentrated in the first half of the night. Charging overlaps with the peak of urban electricity consumption, causing the heaviest burden on the power grid. After the peak of urban electricity consumption in the second...
