Abstract

The invention provides a system and a method for testing electromagnetic interference of an electric automobile and charging equipment. The system comprises a simulation device and a test device; thesimulation device comprises a test automobile and the charging equipment for charging the test automobile; the test device comprises a receiving antenna, and the receiving antenna is installed on an antenna support; the bottom of the test device is also provided with a surrounding assembly, the surrounding assembly comprises an annular guide rail and a sliding table sliding on the annular guide rail, and the antenna support is installed on the sliding table; and the test automobile is arranged in the annular guide rail. According to the system and the method for testing electromagnetic interference of the electric automobile and charging equipment, by adjusting the position relation between the receiving antenna and the test automobile, the electromagnetic interference level of the electric automobile, the charging equipment and a matched charging connection device in the charging process is evaluated comprehensively at multiple angles, meanwhile, the test system is optimized, and thetest cost is reduced.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility testing, and in particular relates to a testing system and method for electromagnetic interference of electric vehicles and charging equipment. Background technique [0002] Conductive charging of electric vehicles refers to the process in which charging equipment supplies electric energy to electric vehicles through charging connection devices. During the actual charging process of electric vehicles, charging equipment, charging connection devices and electric vehicles are in high-voltage and high-current working conditions. At this time, the conductive charging system will generate strong electromagnetic interference signals, and affect the electromagnetic interference inside and outside the vehicle through radiation or conduction. environment, especially the electromagnetic environment of the public grid. From the perspective of protecting the external electromagnetic environment, ...
