Test and analysis of new energy vehicle HV transient waveform

New energy vehicles will generate different HV (high-voltage) transient signals in different working conditions, which pose a threat to the electromagnetic safety of the vehicle. Collection of HV transient waveforms is performed in different new energy vehicles and different working states, and the worst HV transient waveforms are formed by analyzing the data of the collected waveform. The worst HV transient waveforms are used as test signals. The test results show that in a specific state, new energy vehicles have certain immunity to HV transient signals. The methods and data formed during the research process can provide support for the R&D verification tests of enterprises and the formulation of national standards.
