Research on typical design scheme of charging/battery swap infrastructure for electric vehicle

For limiting the construction scale and the layout of charging/battery swap infrastructure, standardization schemes of electric vehicle charging/battery swap infrastructure are researched, and then typical design schemes are raised. Firstly, the typical design scheme compiling principle is described, and specific parameters of serviced electric vehicle and the classification of typical design scheme are provided. On the basis, a typical scheme, including general layout, charging equipment, power supply and distribution system, second order system, civil engineering, fire control, etc., is used as an example for detailedly researching and analyzing the typical design schemes. The design scheme of battery swap system is elaborated in detail, in which charging battery frame, box charger selection and set cabinet, design of battery swap device, battery swap monitoring, battery detection and maintenance are involved. At last, the configuration of typical design schemes is provided. The proposed typical design schemes can be used for unifying the category and selection of equipment and determining the operation and maintenance costs of the charging/battery swap infrastructure, which play an important role in preparing the charging/battery swap infrastructure scheme for all the provinces within the range of State Grid of Corporation of China.
