摘要

The invention relates to an intelligent charging method and system for an electric vehicle on an expressway. The method includes: determining whether a remaining driving mileage of the electric vehicle is greater than a driving mileage corresponding to a remaining power; if yes, collecting electric vehicle information, expressway information and charging station information; determining a shortest path according to the electric vehicle information, the expressway information, and the charging station information; generating a reservation update request according to the shortest path; determining whether there is an update event; if yes, returning to the step of acquiring the remaining driving mileage of the electric vehicle and the driving mileage corresponding to the remaining power of the electric vehicle; if not, sending the reservation update request to a charging station to determine a reservation queue of the charging station; determining whether there is an update event again; if yes, adjusting the reservation queue; charging the electric vehicle according to the adjusted reservation queue; and if not, charging the electric vehicle according to the reservation queue. The invention can make the electric vehicle reach a final destination with shortest total travel time.
