Research on EV Charging Station Capacity under Multi-price Scale

In order to deal with the problems that may arise during the reservation charging process, this article proposes to set up emergency charging piles in the fast charging station and implement a multi-price scale charging mechanism, then, explain the corresponding EV charging and queuing methods. Under the multi-price scale, charging station revenue and user satisfaction were quantitatively characterized in this article, an optimization model was established to solve the optimal ratio of ordinary piles to emergency piles in the charging station. This article analyzes the impact of this ratio on charging station revenue and user satisfaction combined with calculation examples. The results show that multiple price scales has a certain guiding effect on the charging behavior of users, and the reasonable configuration of the number of ordinary piles and emergency piles can increase the revenue of charging stations and improve user satisfaction. The conclusion obtained in this paper can provide guidance for determining the capacity of charging stations that take into account the diverse charging needs of electric vehicle users, user satisfaction and the net income of existing charging stations under multiple price scales, and can provide new ideas for the development of new operating methods for charging stations.
