A remote annunciator for electric vehicle supply equipment includes a housing, and an interface to the electric vehicle supply equipment consisting of a number of power conductors, a number of ground conductors, and a number of control conductors. A plurality of indicators on the housing are structured to provide a remote annunciation function for the electric vehicle supply equipment. A circuit structured to drive the indicators drives the indicators based upon information from only the number of power conductors, the number of ground conductors and the number of control conductors of the interface. The number of control conductors have a control function other than driving the indicators. |
