Simulation Analysis for Electromagnetic Emission Characteristics of Electric Vehicles Based on MATLAB App Designer

Aiming at the electromagnetic interference characteristics of electric vehicles, a simulation analysis software of electromagnetic emission characteristics is designed and developed by using MATLAB App Designer. The software not only realizes the separation of the modeling of vehicle coupling path and the interference source/sensitive equipment characteristics, but also achieves the simulation prediction under the coexistence of multiple interference sources/sensitive equipment. The software is applied to the electromagnetic coupling simulation between in vehicle systems and the electromagnetic radiation emission prediction of high-voltage system outside the vehicle under the real vehicle state; The software has the characteristics of convenient operation and rapid iteration, which can shorten the vehicle development cycle and reduce the development cost.
