Electromagnetic compatibility requirements and test methods of drive motor system for electric vehicles
1 Scope
This standard specifies the electromagnetic compatibility requirements and test methods of drive motor system for electric vehicles.
This standard is applicable to drive motor systems for battery electric vehicles, hybrid electric vehicles and fuel cell electric vehicles.
This standard considers the components of HV (high voltage) power supply system as a typical fully shielded system.
Note: There are usually two types of power supply systems for electric vehicles: the common LV (low voltage) system with a typical feature of unshielded structure, and the HV system with a typical feature of shielded structure.
