Abstract

The invention discloses a vehicle-mounted charging assembly electromagnetic compatibility test system and a control method thereof, and belongs to the technical field of automobile electronic electromagnetic compatibility test, wherein the vehicle-mounted charging assembly electromagnetic compatibility test system comprises a vehicle-mounted charging assembly and a water pump which are respectively arranged on the inner side and the outer side of a dark room, and the water pump is connected with the vehicle-mounted charging assembly; a high-voltage power supply is arranged outside the dark room and connected with the vehicle-mounted charging assembly through a high-voltage artificial network, a water-cooling load is arranged inside the dark room and connected with the water pump through a water pipe, and a control machine is arranged outside the dark room and obtains test data of the vehicle-mounted charging assembly through an antenna arranged inside the dark room. The problem of test stop caused by over-temperature protection is solved, the 14 / 27V switch toggle type adjustable water-cooling load is designed, the load overheating condition is avoided, noise is reduced, and the test efficiency is improved; and the water-cooling load is designed, extra electromagnetic disturbance caused by heat dissipation of a traditional fan and a motor, and test failure is caused are solved.

Description

technical field [0001] The invention discloses a vehicle-mounted charging assembly electromagnetic compatibility testing system and a control method thereof, belonging to the technical field of automotive electronic electromagnetic compatibility testing. Background technique [0002] With the continuous popularization and application of new energy vehicles, DC converters & on-board chargers are essential components of new energy vehicles, and the electromagnetic compatibility testing of components for the vehicle's stability, safety and reliability play an important role in safeguarding. [0003] During the electromagnetic compatibility test, the internal temperature of the on-board charger is often too high due to the long test time, causing the over-temperature protection of the on-board charger to stop working. [0004] During the test, in order to meet the test load specified by different products, it is necessary to adjust the load to control the working condition of t...
