Electric vehicles can cut the load peak of grid，reduce the emission of CO 2 ，and the planning method and model of charging infrastructure can guide its construction so as to support the development of electric vehicles.This paper presents the systematic process and practice of planning of the charging infrastructure.Based on energy equivalence，a criterion namedequal product of load and distance”and some parameters are given to allocate charging energy to centralized and scattered charging infrastructures.The charging load is forecasted and then the location and capacity are confirmed.Finally，the economics of the plan is evaluated by the net present value method，and its convenience is evaluated by theaverage distance of the electric energy charging”method till the final plan is obtained.
