Abstract

The invention discloses a detection method and device for a direct current charging pile. The detection method comprises the following steps: simulating consistent output of the direct current charging pile by virtue of a BMS simulator of a battery management system; simulating on-off control of a charging loop of the direct current charging pile by virtue of a direct current charging pile interface circuit simulator, and collecting signals before and after the loop is put through and cut off; simulating the load of an electric automobile charged by the direct current charging pile by virtue of a load system AV900; controlling the BMS simulator, the direct current charging pile interface circuit simulator and the load system AV900 by virtue of a master control machine, so as to finish thedetection of the direct current charging pile, wherein the detection of the direct current charging pile comprises communication protocol consistency testing and interoperability testing. According tothe detection method, the problems of long testing time and low testing efficiency of the charging pile caused due to insufficient automation degrees in relevant techniques are solved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a method and device for detecting a DC charging pile. Background technique [0002] With the continuous aggravation of environmental pollution and energy crisis, the application of new energy electric vehicles has been paid more and more attention and widely promoted, but users generally report many problems related to power supply such as many charging problems and poor battery life of electric vehicles during use. . Therefore, in recent years, a lot of research has been done on the improvement of electric vehicle power supply and power consumption performance in related technical fields, and a lot of efforts have been made on the standardization and intelligent development of the use of electric vehicle charging equipment. However, there are still certain disadvantages at this stage. For example, in order to solve the problems of electric vehicle charging and ...
