Abstract

The invention provides an electromagnetic compatibility comparison test arrangement method for electric drive systems, which comprises the following steps of: arranging a reference laboratory and a comparison laboratory, arranging the electric drive systems in the reference laboratory and the comparison laboratory, and arranging the position spacing of each part of the electric drive systems according to a manually set value; respectively comparing the arrangement deviations of the position spacing of each part in the reference laboratory and the position spacing of each part in the comparison laboratory; under the same frequency domain state, electric parameter deviation detection is carried out on the electric drive systems in the reference laboratory and the comparison laboratory; if the position spacing arrangement deviation value of each part in the comparison laboratory is smaller than or equal to 10% and the electrical parameter detection deviation value in the comparison laboratory is smaller than or equal to 10%, the comparison laboratory setting is qualified. According to the electromagnetic compatibility comparison test arrangement method for the electric drive system, environmental factors which possibly occur in laboratory arrangement and influence test data are eliminated from the two aspects of position spacing and electrical parameters of all the components, and the test authenticity and reliability are improved.

Description

Technical field [0001] The present invention belongs to the field of electromagnetic compatibility testing, in particular to an electromagnetic compatibility energy comparison test arrangement method for an electric drive system. Background [0002] With the development of new energy vehicles, the electromagnetic compatibility of electric vehicles is becoming more and more important in automobile safety, and the electromagnetic compatibility of electric drive systems is the main aspect affecting the electromagnetic compatibility of electric vehicles. Electric drive system electromagnetic compatibility energy test is mainly completed in the electromagnetic compatibility darkroom, the current industry can realize the electromagnetic compatibility of the electric drive system electromagnetic compatibility test more and more institutions, but the equipment used, the site environment, etc. are different, the measured results are also quite different, so it is necessary to carry out th...
