The comprehensiveness

rapidness and economy of charging service is one of main factors that influences the popularity of electric vehicles

and the construction and management of charging facilities in a residential area play a key role. Because of the limited capacity and other reasons

the development of charging facilities in the residential area falls behind the other forms of charging energy. Based on the practical charging conditions of a typical residential area

the influence of possible technical/market measures on the battery electric vehicle(BEV)charging process is discussed according to the detailed simulation of charging process for BEVs and its effect and value are quantitatively analyzed. On the basis of defining BEV charging contract model

the analysis mentioned above is put forward to propose an optimization method according to the charging strategy based on the optimal value network and the algorithm is verified to be effective by the examples. The simulation results indicate that on the condition of limited capacity

compared to the existing disordered charging mode

the ordered charging/discharging mode under the centralized management can obviously increase the capacity of charging service in the typical residential area by improving the efficiency inside. Moreover

the interactive capacity of emergency backup for the grid by BEV is improved and the revenue channels and comprehensive benefits increase as well.
