Abstract: Ultrafast charging for electric vehicles (EVs) could offer a solution for drivers requiring high travel flexibility and raise the prospect of swift replacement of conventional gasoline/diesel vehicles. Yet, serious concerns exist regarding the impact on the power grid and the solutions to adopt when power distribution networks cannot provide adequate capacity. In this presentation, Dr. Yang Zhao will show first the real-world charging patterns and station loads of several representative fast-charging stations in China. The simulations for the increase in charging power in conjunction with real-world EV charging patterns are used to quantify the impact of future ultrafast charging station loads. The results indicate that the marginal increase in station loads is not as significant as the increase in EV charging power. Generalized solutions for charging stations to address insufficient total power capacity are studied including dynamic waiting strategies and use of energy storage. Lastly, the primary device costs of different charging station upgrade strategies are discussed.
