中文摘要：

购买电池的初期投资大、电池充电时间长以及分布式随机充电对电网负面影响大是制约电动汽车发展的重要因素。基于里程计费的换电池模式实际上采用了电池租赁模式和慢充技术，而且可以通过建立规模庞大的集中型充电站为电池进行充电，因此为当前电动汽车发展问题具有竞争力的解决方案。但是作为新生事物，集中型充电站规划建设缺乏科学理论指导，从区域各类型电动汽车的电池组充电需求出发，在综合考虑集中型充电站建设初期购置设备费用和运行期间购买电能费用的基础上，建立了集中型充电站最优容量配置模型，数值算例仿真验证了模型的有效性相关分析表明，电池组需求和充电电价设置对集中型充电站的容量规划影响巨大。

英文摘要：

The high initial investment of battery, the long charging time, and the negative effect on the power grid due to the electric vehicles＇ distributed and random charging, are the main factors that limit the development of electric vehicles （EVs）. The battery swapping mode actually applies battery leasing model and the slow charging technology, and large-scale centralized charging station can be built to recharge the battery, which has become a competitive way to solve this key problem. As a new-born thing, it is lack of theoretical guidance for the planning and operation of large-scale centralized charging station. Given the regional charging demand and considering the initial investment of equipment and the electric energy cost during the operation period, a capacity planning model for centralized charging station was established. The effectivity of the model was tested by a numerical example. Relative analysis demonstrates that battery demand and charging tariff will have great influence on the capacity planning of the centralized charging station.
