Which component is connected to the charge controller of a wireless EV charger via hardwiring?

The correct answer is the power source coil. In a wireless electric vehicle (EV) charging system, the power source coil is responsible for transmitting electrical energy from the power source to the charger. This coil generates an electromagnetic field that transfers energy wirelessly to the vehicle's receiver coil.

The connection of the power source coil to the charge controller via hardwiring is crucial because it allows for efficient management of the energy transfer process, ensuring that the system operates at optimal levels. The charge controller regulates the energy flow, adhering to the requirements of safe and effective charging for the EV's battery, thereby balancing the demand and supply of power.

The other components, such as the power capture resonator, power control unit, and power multiplier coil, play important roles in the wireless charging system as well but do not directly connect to the charge controller through hardwiring. The power capture resonator primarily works to capture the energy from the electromagnetic field created by the power source coil, while the power control unit governs the operation of the entire system. The power multiplier coil is typically involved in boosting the power levels for efficient transmission.
