Research on Test Method for Shielding Effectiveness to Cable of Vehicles 2019-01-5070
With the development of electric vehicles (EVs), hybrid electric vehicles (HEVs) and fuel cell vehicles (FCVS), high voltage and large-current are applied to cables. Therefore, it is important to avoid electromagnetic compatibility (EMC) problems of cables, and a measurement methods is necessary for the shielding effectiveness of shielding cables. This paper discusses the existing test methods of cable shielding effectiveness and summarizes the main problems and deficiencies. Then, according to the practical requirements of high voltage cable testing, the direct injection method based on the national standard GB/T 18655-2018 (modified international standard CISPR 25) is proposed. The test method is verified by constructing a practical test platform. The test result show that the platform built can meet the test requirements of the new energy vehicles (NEVs) GB/T 18387 test frequency band 150k~30MHz, and can also meet the test requirements of the 150k~108MHz frequency band of the key component conducted emission of NEVs.
