Research on path optimization of electric distribution vehicle with hybrid charging strategy

Abstract

At present, the number of new energy vehicles in China is increasing year by year. In the field of logistics and distribution, new energy vehicles are also showing vigorous vitality. This paper presents a two-stage optimization method for electric vehicle routing problem with hybrid charging strategy. In the first stage, a fuzzy transitive closure method is used to group customer orders, in the second stage, the decision variables and constraints related to the charging strategy are introduced, and a mixed integer linear programming model considering the three charging strategies of fast charging, slow charging and fast switching is constructed, finally, the validity of the proposed model is verified by a instance.
