Abstract
A charge head is connected to a charge inlet of an electric vehicle to supply an electric charge to recharge the battery of the vehicle. The charge head is attached to a connecting device that moves the charge head to the charge inlet. Multiple light detectors are provided on the charge head to sense light emitted from the vehicle. The system then uses a difference in the amount of light received by different light detectors to determine a direction to move the charge head toward the charge inlet.
