Research on Transient Waveform Acquisition and Injection Methods for Vehicle High Voltage Ports
The test items involved in the existing vehicle electromagnetic compatibility standards are all tested in static,uniform speed driving,and AC/DC charging and other stable states.There are few studies on rapid acceleration,rapid deceleration,and transient conditions such as locking off the car,unlocking on the power,charging start and end,and there are no relevant test standards.Through an overview of the acquisition location,vehicle status and acquisition methods of the high voltage transient waveform,the paper focuses on the waveform acquisition and injection methods of new energy vehicles in the running state,which is a new exploration for the study of the waveform of the high voltage port of vehicles.The research methods and data can not only provide data and method support for the research and verification of enterprises.It can also provide data and technical support for the formulation of national standards.
