电动汽车交流充电桩测得值的不确定度分析

Uncertainty analysis of measurement results of AC Charging Spot Electrie Vehicles

电动汽车交流充电桩按接入电压分直流充电桩和交流充电桩。电动汽车交流充电桩按准确度等级可分为1级和2级。文章主要介绍了用电动汽车交流充电桩检定装置现场检定1级电动汽车交流充电桩测量基本误差的测量不确定度和测量不确定度的评定方法。

The charging piles of electric vehicles are divided into DC charging piles and AC charging piles according to the access voltage.The AC charging pile of electric vehicle can be divided into grade 1 and grade 2 according to the accuracy grade.This paper mainly introduces the measurement uncertainty and the evaluation method of the measurement uncertainty of the basic errors in the field verification of grade 1 electric vehicle AC charging pile with the verification device of electric vehicle AC charging pile.
