Abstract

The invention provides a system and method for testing alternating current charging electromagnetic interference of an electric vehicle. The system comprises an alternating current simulation chargingunit and an electromagnetic interference test unit. The alternating current simulation charging unit is used for charging a to-be-tested vehicle. The electromagnetic interference test unit comprisesa radiation emission test circuit and a conduction emission test circuit. The radiation emission test circuit is used for acquiring radiation interference formed by a tested vehicle in an alternatingcurrent charging state. The conduction emission test circuit is used for acquiring conduction interference formed on the power line of the tested vehicle in the alternating current charging state. According to the system and method for testing the alternating current charging electromagnetic interference of the electric vehicle, the actual charging working condition of the whole vehicle can be accurately simulated, and the influence of other equipment or factors on the test result is effectively eliminated.

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 AC charging of electric vehicles. Background technique [0002] AC charging for electric vehicles means that the AC power grid sequentially passes through AC charging equipment, charging connection devices, and on-board chargers to adjust the power frequency 50Hz single-phase or three-phase AC to a calibrated voltage / current, so as to realize electric vehicle power batteries, etc. The process by which an energy storage device provides electrical energy. [0003] During the AC charging process of electric vehicles, components such as power batteries, on-board chargers, high-voltage distribution boxes, and high-voltage power lines are in high-voltage and high-current working conditions. On the one hand, the vehicle will generate strong electromagnetic interference signals, and through ra...
