Abstract
A door latching system for the door covering the charge port of an electric vehicle, or for the door covering the fuel filler port of a conventional vehicle, is provided. The door latching system is comprised of a ferromagnetic member attached to an interior surface of the door, and a latching assembly integrated into the port housing, where the latching assembly includes an assembly case, an electromagnet, and a permanent magnet that maintains the door in a closed position when the electromagnet is not energized and releases the door when the electromagnet is energized. The latching assembly may include a magnetic flux sensor that monitors when the port door is open or closed. The magnetic flux sensor may be coupled to a system controller that performs a preset response when the magnetic flux sensor determines that the door is open.
