Abstract
In face of a complex electromagnetic environment, the ability of the electric vehicle (EV) to resist electromagnetic interference (EMI) is crucial, which could ensure the safety of the EV on the road. In this paper, the research on electromagnetic susceptibility (EMS) test and analysis for the EV is carried out. Based on the off-vehicle radiation source method and the bulk current injection (BCI) method, the EMS tests are conducted for the whole EV system in driving state and its key components. Results show that the vehicle control unit (VCU) is one of the most susceptible components to EMI in the EV system. The analysis points out that there is a certain correlation between the EMS of the whole EV system and its key components.
