Research on applicability of "full coverage method" in GB 34660 same type determination on high-voltage system of electric vehicle

Electric vehicle(EV) has a variety of high-voltage(HV) system configurations. To reduce testing cost, "full coverage method" is proposed in "GB 34660 same type determination technical requirements". In this paper, the applicability of this method is analyzed by measuring common mode current and radiation with five HV system configurations. The preliminary results suggest that every configuration of HV system should be tested for accurate test result.
