An apparatus including a first electrical connector; and a second electrical connector. The first and second electrical connectors have magnets to provide a magnetic holding force with each other and provide alignment of the electrical connectors to hold the second electrical connector against the first electrical connector at a predetermined position. Magnetic poles of the magnets are configured to limit orientation of the second electrical connector on the first electrical connector. The second electrical connector includes two power contacts and an interruption detector contact, where the power contacts are movably mounted on the second housing and configured to disconnect from electrical contacts of the first electrical connector, when the second electrical connector is being disconnected from the first electrical connector, only after the interruption detector contact of the second plurality of electrical contacts disconnects from an electrical contact of the first electrical connector.

A system and method for locking a charging port to charge an electric vehicle that includes determining that the electric vehicle is located within a predetermined distance of a charging station and determining when the charging port of an electric vehicle supply equipment of the charging station is attached to the electric vehicle to actively charge the electric vehicle. The system and method also include determining if the charging station accesses a parking citation associated with parking of the electric vehicle if the electric vehicle is not attached to the charging port. The system and method additionally include locking the charging port to the electric vehicle to disallow decoupling of the charging port from the electric vehicle by an unauthorized individual to avoid the parking citation.
