A coil alignment method performed in a vehicle-side coil alignment apparatus coupled to a vehicle assembly (VA) controller includes: moving a light-blocking unit protruding from a vehicle parked in a wireless charging area in a first direction toward the ground facing one side of a vehicle-side wireless power transfer pad which is mounted on the vehicle and includes a VA coil, where the light-blocking unit protrudes from the one side of the vehicle-side wireless power transfer pad; stopping movement of the light-blocking unit in response to a first stop signal from a ground assembly (GA) controller; moving the light-blocking unit in a second direction perpendicular to the first direction; and stopping movement of the light-blocking unit in response to a second stop signal from the GA controller.
