Abstract

Abstract:

With the development of new energy technology, the application of multi-frequency devices and high-voltage wire harness makes the electromagnetic compatibility of new energy vehicles become more and more complicated. It is of great engineering value to study the complex electromagnetic environment effect and protection of the new energy charging cable of special vehicle. In this paper, a new energy charging cable was selected, and the electromagnetic interference source and the charging cable model were established by using the three-dimensional electromagnetic field simulation software (CST). Based on the field-line coupling principle, the electromagnetic response of recharged cables in hybrid armored vehicles irradiated by high altitude nuclear electromagnetic pulse was simulated and analyzed. The simulation results showed that the larger the cross-sectional area of the same cable, the greater the coupling current of the cable port. Under the same interference pulse, the peak time and the beginning attenuation time of the coupling current at different cable ports were different, and the cable layout affected the coupling current at the cable port. The coupling current of cable impedance matching was much larger than that of load impedance mismatch, and the high altitude nuclear electromagnetic pulse response of new energy charging cable was in good agreement with that of traditional SYV-50-3 coaxial cable.
