In wireless charging, the device external to the electric vehicle that transfers power via contactless coupling is called the:

• A. Charging station
• B. Primary pad
• C. Touchless power supply
• D. Wireless transfer

Answer: (B)

In wireless EV charging, power is transferred by inductive coupling between two coils: a transmitter on the outside device and a receiver on the vehicle. The device placed externally to the EV that delivers the power is the primary pad—the ground or plate that’s connected to the power source and generates an alternating magnetic field to transfer energy across a small air gap. The vehicle side has the secondary coil that captures that energy and converts it for the battery. A charging station is a broader term for the overall system, not the specific external transfer device. “Touchless power supply” and “wireless transfer” are generic descriptions, not the standard hardware name. So the best fit is the primary pad.
