中国电动汽车充电桩发展趋势及其计量需求
Development Tendency and Metrology Demand of Charging Pile for Electrical Vehicles in China

大力发展电动汽车和配套的充电设施是实现碳达峰和碳中和目标的重要途径之一。随着城市电动汽车保有量的与日俱增，满足大量居民的充电需求、提升城市整体的充电效率正在成为许多城市的重要问题。作为电能贸易的主要贸易载体之一，充电桩充电的贸易公平、安全认证和服务标准化是决定电动汽车充电设施产业发展态势的重要因素。本文首先分析了中国电动汽车充电桩的发展趋势，指出车桩位一体化的发展思路是解决城市电动汽车充电困难的有效途径。在此基础上，分析了电动汽车充电产业中开展检测计量、认证业务和研究的必要性。进而在分析综述现有充电桩的计量检定方法的基础上给出了电动汽车充电产业中检测计量和认证相关研究思路和建议，为后续研究提供参考。
Vigorously developing electric vehicles and corresponding charging facilities is one of the important ways to achieve carbon peaking and carbon neutrality. With the increasing number of electric vehicles in cities, meeting the charging needs of a large number of residents and improving the overall charging efficiency of the city are becoming an important issue in many cities. As one of the main trade carriers of electric energy trade, the trade fairness, safety certification and service standardization of charging pile are important factors that determine the development trend of the electric vehicle charging industry. This paper first analyzes the development trend of charging piles for electric vehicle in China, and points out that the development framework of the integration of vehicles, charging piles and parking spots is an effective way to solve the problem of urban electric vehicle charging. On this basis, the necessity of implementing testing, metrology and certification business and research in the charging industry of electric vehicles is analyzed. Then, based on the review of existing metrology method of charging pile, some research ideas and suggestions on the testing, metrology and certification in the electric vehicle charging industry are given, which provides references for subsequent research.
