Electric vehicle wireless power transfer - Part 4: Limits and test methods of electromagnetic environment
1 Scope
This part of GB/T 38775 specifies the limits and test methods of electromagnetic environment inside and outside the electric vehicle under wireless power transfer.
This part is applicable to the stationary magnetic field wireless power transfer, wherein, the maximum rated voltage of the power supply is 1,000V AC or 1,500V DC, and the maximum rated output voltage is 1,000V AC or 1,500V DC. The primary device is erected underground or above ground.
