Abstract

A cover assembly for a charging port of an electric machine includes a head plate, a non-metallic base plate, and a flexible membrane. The head plate extends across an opening of an outer panel assembly of the machine to define an aperture. The non-metallic base plate is movable with respect to the head plate to selectively open and close the aperture. The flexible membrane is fixedly coupled to the head plate and slidably engaged to the non-metallic base plate to enable the non-metallic base plate to slide with respect to the head plate and move between a folded state and an unfolded state with respect to the head plate. In the unfolded state, the non-metallic base plate closes the aperture, and, in the folded state, the non-metallic base plate opens the aperture to allow access to the charging port from an outside through the aperture.
