为了使电动汽车更具吸引力并实现更大的普及，拥有一个快速充电站网络似乎是必要的。目前，50千瓦的快速充电器可以在大约一个小时内为一辆普通的电动汽车充电。然而，标准中引入了能在10分钟内给一辆普通电动汽车充电的240千瓦快速充电水平。预计这种高功率快速充电器将在不久的将来上市。当多辆电动汽车同时进行快速充电时，充电站必须提供数兆瓦级的充电功率。在这里，充电站拓扑在实现未来增长和提供最佳服务质量、最低成本和最小电网影响的快速充电方面发挥着至关重要的作用。本文介绍了文献中充电站的拓扑调查。基于电网支持度、功率密度、模块化等因素，对不同的充电站拓扑结构进行了比较和评价。
Having a network of fast charging stations seems necessary in order to make EVs more attractive and to achieve larger uptake of them. Currently, 50 kW quick chargers that can charge a typical EV in about an hour are commercially available. However, a 240 kW fast charging level which can charge a typical EV in 10 minutes has been introduced in standards. It is expected that this high power fast chargers will be available in near future. A charging station must supply charging power in multi-megawatt levels when multiple EVs are being fast charged simultaneously. Here, charging station topology plays a crucial role in enabling future growth and providing fast charging with best quality of service, lowest cost and minimum grid impact. This paper presents a topological survey of charging stations available in the literature. Various charging station topologies are presented, compared and evaluated based on grid support, power density, modularity and other factors.
