新能源充电桩计量特性工作误差不确定度评定方法及分析

Evaluation Method and Analysis of Measurement Uncertainty of Metering Characteristics of New Energy Charging Piles

计量特性的不确定度是表征合理地赋予被测量之值的分散性,与测得值相联系的参数。不确定度表明其测得值的可信赖程度,同时不确定度的评定对其测得值意义非常重要。本文依据直流充电桩检定规程,结合测量实例,详细介绍了直流充电桩检定装置检定1级新能源充电桩计量特性工作误差不确定度评定方法及分析。

The uncertainty of measurement characteristics is a parameter that represents the dispersion of the measured value reasonably assigned and is related to the measured result.The uncertainty indicates the reliability of the measurement results,and the evaluation of the uncertainty is very important to the measurement results.Based on the verification regulation of DC charging pile and combined with measurement examples,this paper introduces in detail the evaluation method and analysis of working error uncertainty of new energy charging pile measurement characteristic verification by DC charging pile verification device.
