摘　　要：电动汽车交流充电桩校验仪、电动汽车直流充电机校验仪是电动汽车充电桩/机的计量标准器,其准确可靠可为强检计量器具电动汽车充电桩/机的量值提供保证。通过对国内电动汽车充电桩/机校验仪的长期全面测试和理论研究,较全面掌握了电动汽车充电桩/机校验仪的生产水平和质量状态,在大量实际数据的支撑下,对最小电流、温度系数、失真度、纹波等进行了溯源研究,掌握了关键参数值和检测方法,为相关国家规程的编写打下坚实基础。Electric vehicle AC charging pile calibrator and electric vehicle DC charging machine calibrator are the measurement standard for electric vehicle charging piles/machines, and its accuracy and reliability is to ensure the quantity of electric vehicle charging piles/machines. Through a long-term comprehensive test and theoretical study of domestic electric vehicle charging pile/machine calibrators, we have a relatively comprehensive grasp of the production level and quality status of electric vehicle charging pile/machine calibrators. With the support of a large number of actual data, the minimum current, temperature coefficient, distortion, ripple and other sources have been studied. The key parameter values and detection methods have been mastered, which lays a solid foundation for the preparation of national regulations.
