Claim 0:
1. A secure enclosure to be included in a direct current (DC) electric vehicle supply equipment (EVSE), the secure enclosure comprising:
a set of one or more contactors to open and close to provide DC charge transfer with a set of one or more electric vehicles;
a conductor to electrically connect the set of one or more contactors to DC input from a set of one or more power converters to convert alternating current (AC) mains power to direct current (DC) power, wherein the set of one or more power converters are external to the secure enclosure;
a current sensor to measure current draw;
a voltage sensing circuitry to measure voltage; and
one or more circuits that receive current data from the current sensor and voltage data from the voltage sensing circuitry, the one or more circuits to perform one or more safety functions and one or more metering functions using the received current data and voltage data, and to transmit metering data to a controller of the DC EVSE that is external to the secure enclosure.
