A coil alignment method performed in a coil alignment apparatus coupled to a VA controller includes: sensing magnetic field intensities induced from a ground assembly (GA) coil through a first auxiliary coil and a second auxiliary coil which are fixedly coupled to a VA coil; comparing a first magnetic field intensity sensed through the first auxiliary coil with a second magnetic field intensity sensed through the second auxiliary coil; moving the VA coil or the GA coil to a position where there is a predetermined difference or less between the first magnetic field intensity and the second magnetic field intensity; and moving at least one of the VA coil and the GA coil in a direction facing each other, so that a center point of the VA coil and a center point of the GA coil are located within a shortest distance of each other or within a certain error range of the shortest distance, while maintaining the predetermined difference or less between the first magnetic field intensity and the second magnetic field intensity.
