Abstract

The invention discloses an electric vehicle dynamic charging method and system based on a shortest Hamilton loop. The electric vehicle dynamic charging method comprises the following steps of determining electric vehicles needed to be charged in a predetermined area according to the running path, current power consumption rate, residual electric quantity and current position of each electric vehicle, calculating the distance between each electric vehicle needed to be charged and a charging station closest to the electric vehicle, calculating the shortest charging time of an electric power supplementing vehicle for each electric vehicle needed to be charged according to the distance between each electric vehicle needed to be charged and the charging station closest to the electric vehicle, determining the running route of the electric power supplementing vehicle based on the shortest Hamilton loop, and controlling the electric power supplementing vehicle to sequentially charge all electric vehicles needed to be charged according to the running route of the electric power supplementing vehicle and the shortest charging time of the electric power supplementing vehicle for each electric vehicle needed to be charged. The electric vehicle dynamic charging method has the advantages of being high in flexibility and saving the cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicles and computer communication, in particular to a dynamic charging method and system for electric vehicles based on the shortest Hamiltonian circuit. Background technique [0002] At present, the development and popularization of electric vehicles are facing many challenges, the most serious of which is the limited power storage capacity of on-board batteries, and electric vehicles need to be recharged many times when driving for a long distance. In resource-intensive metropolises, a large number of charging stations can be established. When the power is insufficient, electric vehicle owners can choose the nearest charging station to replenish the power in time. However, when an electric vehicle travels for a long distance or travels to a remote area, it is inevitable that the battery will run out and the vehicle cannot continue to drive. At the same time, electricity is a kind of energy t...
