摘要
Abstract
The DC charging pile of the existing electric vehicle (EV) has the characteristics of high output of voltage and current and both of them have ripple at the same time.The impact of ripple on the measurement accuracy was not taken into account in the traditional DC energy meter under high power working conditions.Based on the working principle of the charging pile,the characteristics of the output ripple of DC charging pile and the workirig principle of the DC energy meter or metering module,the errors of the different algorithms are analyzed in this paper.The regularity of ripple effects is analyzed,and a standard source and a standard DC meter are used to verify it.The error of the ripple on the DC energy measurement is determined quantitatively,and all about this research provides the basis for the accurate measurement of DC charging energy and the optimization of DC metering algorithms.关键词
