In view of the increasing charging demand of electric vehicles

a construction pattern of AC charging piles is established through analyzing the influencing factors

such as the overall demand on electric vehicle charging quantity

multi-scenario operation mode and the commercial operation mode. The objective function of the construction pattern is to minimize the fees of charging piles construction and management

the running fees of the on-the-road electric vehicles and the waiting fees. The simulation solving process of the model is also given. The feasibility of the AC charging piles construction pattern is validated by example

and the number and location of the charging piles can be pre-computed in one area according to the quantity of regional electric vehicles. The study can effectively reduce the construction costs of AC charging piles while promoting the development of the electric vehicle industry faster

and more healthily and effectively.
