Claim 14:
15. A method performed in a direct current (DC) electric vehicle supply equipment (EVSE), comprising:
converting alternating current (AC) mains power to DC power, wherein the converting AC mains power to DC power is performed externally to a single enclosure of the DC EVSE;
controlling opening and closing of a set of one or more contactors that are within the single enclosure of the DC EVSE to provide DC charge transfer with a set of one or more electric vehicles, wherein the set of one or more contactors are electrically connected to the DC power by a set of one or more conductors, wherein the controlling opening and closing of the set of one or more contactors is performed externally to the single enclosure of the DC EVSE;
measuring, within the single enclosure of the DC EVSE, current draw for the DC charge transfer with the set of one or more electric vehicles;
measuring, within the single enclosure of the DC EVSE, voltage; and
performing, within the single enclosure of the DC EVSE, one or more safety functions and one or more metering functions using the measured current draw and the measured voltage.
