中文摘要：

换电模式由于其众多优点目前已发展成为电动汽车的重要能源供给模式。当前全国大部分省市都开展了电动汽车换电网络的规划和建设，但学术界有关换电模式的理论研究还较为滞后，远远不能满足该领域发展的需要。鉴于此，文章概述了换电模式在国内外的发展现状，分析了集中充电以及充换电2种换电模式的结构及特点。介绍了换电网络的基本框架、运营模式以及换电网络管理系统。针对换电网络的规划与运行进行了详细分析，从电池数量、充电站的选址定容2个方面对换电网络的规划问题进行了研究；并分析了换电网络在实际运行阶段该如何进行电池调配以及充电管理。最后总结了换电模式发展所面临的瓶颈，并对今后的研究方向进行了展望。

英文摘要：

Owing to its advantages, the battery-swapping mode is developed into an important energy supply mode of electric vehicles （EV）, and at present the planning and the construction of battery-swapping networks are being carried out in major provinces and large cities in China, however the theoretical research in this field lags behind its application and dissemination and cannot meet the demand of the development in the field. Present developing situation of battery-swapping mode home and abroad is summarized, and the structure and features of two battery-swapping modes, namely the centralized charging mode and the charging and battery-swapping mode, are analyzed. The basic frame, operation mode and management system of battery-swapping network are presented. The planning and operation of battery-swapping network are analyzed in detail, and from the two aspects, i.e., the amount of batteries and the site selection and capability determination of charging station, the planning of battery-swapping network is researched; the battery dispatching strategy and battery charging management during practical operation phase of battery-swapping network are analyzed. Finally, the bottlenecks that the development of battery-swapping mode has to be faced with are enumerated, and research direction of this problem in future is prospected.
