Electric vehicle path scheduling method for wireless charging through bus network

Abstract

The invention discloses an electric vehicle path scheduling method for wireless charging through a bus network, and the method comprises the steps: formalizing an electric vehicle path scheduling problem for an electric vehicle wireless charging system based on the bus network, and maximizing the total residual energy of all electric vehicles; then, for the bus network assisted electric vehicle path scheduling problem which does not consider conflicts, a path scheduling algorithm is adopted to obtain a path allocation scheme of the electric vehicles; for the conflict-considered bus network-assisted electric vehicle path scheduling problem, a conflict-avoiding path scheduling algorithm is adopted to obtain an allocation scheme between electric vehicles and charging road sections or paths. Time constraint and battery energy constraint of an electric vehicle user are met at the same time; and the method has the advantages in the aspects of maximizing the total residual energy and optimizing the time cost.

Description

technical field [0001] The invention belongs to the technical field of wireless charging optimization and path optimization, and in particular relates to a path scheduling method for an electric vehicle wirelessly charged through a bus network. Background technique [0002] The widespread application of electric vehicles can not only reduce carbon emissions, but also change the dependence of fuel vehicles on traditional oil resources to electricity resources. However, the popularization of electric vehicles faces many challenges. First of all, energy constraints limit the range of electric vehicles, and large-scale charging stations need to invest a lot of money and occupy a lot of land resources. Secondly, electric vehicle users always want to arrive at their destination before the specified deadline, such as attendance, appointment and meeting deadlines, etc. At this time, it is impossible to ask EV users to spend a lot of time charging EVs. Furthermore, traditional ele...

Problems solved by technology

However, in the wireless charging system, the path scheduling of electric vehicles faces the following problems: on the one hand, the path scheduling of electric vehicles must meet the deadline constraints and energy constraints, and the single-objective shortest path algorithm cannot directly solve the above problems; on the other hand, the electric vehicle It is necessary to go through a precise charging section during driving, so the choice of charging section will greatly affect the energy consumption and driving time of electric vehicles; further, if considering the same charging section, a bus can only charge one electric vehicle , then the dedicated charging section will affect the path scheduling of different electric vehicles, which makes the path scheduling problem of electric vehicles more complicated
