doi:10.16628/j.cnki.2095-8188.2021.05.012

Abstract

Abstract:

In this paper,the main factors of the measurement results and the causes of dissatisfaction are analyzed when the participating laboratories perform the timing measurement of the charging connection control of the electric vehicle AC charging pile according to the GB/T 18487.1—2015 standard during the implementation of the proficiency testing plan.The main purpose of this paper is to enable the participating laboratories to have a deeper understanding of the technical requirements of the standard.The participating laboratories with unsatisfactory results can find out the problems and take effective measures to rectify them,so as to ensure the accuracy of daily monitoring in the future or obtain satisfactory results by participating in the capability verification again.

Key words: electric vehicle, AC charging pile, proficiency testing, charging connection control timing sequence
