New Energy Vehicle Electromagnetic Compatibility Test and Closed-Loop Simulation Analysis

Abstract

With the rapid development of new energy vehicles, electromagnetic compatibility of new energy vehicles has been widely concerned. Therefore, based on the conducted electromagnetic interference theory of electric vehicle electric drive system, a kind of electromagnetic interference transmission path is proposed, and its closed-loop simulation is carried out. The results show that the key point that has great influence on the radiation emission of the electric drive system is whether there is a torque, essentially whether the motor controller has power output, and it has little relation with the motor speed and bus voltage. In addition to the influence of whether or not the torque has on radiation emission, the torque size is further compared, set 50 Nm, 100 Nm, and 200 Nm, respectively, for comparison, and it is found that the increase of torque has no obvious influence on radiation emission. Therefore, during the test, the appropriate torque can be selected according to the actual situation, rather than the maximum torque that the component can work.
