ELECTRIC VEHICLE CHARGING SYSTEM WITH PRIORITY CHARGING

Abstract

An electric vehicle (EV) charging system includes a controller comprising a central processing unit and implemented on a single printed circuit board, and a first output connection and a second output connection each coupled to the controller and operable to deliver power via the AC power supply. The controller is operable to direct the AC current from the higher voltage side of the printed circuit board to the first output connection comprising a first output head operable to charge an EV, detect a load on the second output connection, halt the AC current directed to the first output connection responsive to detecting the load on the second output connection, and direct the AC current from the higher voltage side of the printed circuit board to the second output connection after halting the AC current directed to the first output connection.
