Abstract

A charge port illumination system for an electric vehicle includes a charge port at an electric vehicle for electrically connecting to a charging source to charge a power source of the electric vehicle. A self-contained sealed module is disposed at or proximate to the charge port and includes at least one illumination source. The illumination source, responsive to an activating event associated with an electric charging event of the electric vehicle, is activated to provide illumination at the charge port. The activating event may include detection of touch at or movement of a cover panel and/or a signal from a remote transmitting device or a passive entry device or a motion detection device. The illumination source may be automatically deactivated after at least one of a period of time after activation, plugging in a charging source at the charge port and closing a cover panel at the charge port.
