Abstract
A direct current (DC) electric vehicle supply equipment (EVSE) that includes a secure enclosure. The secure enclosure encloses a set of one or more contactors to open and close to provide DC charge transfer with one or more electric vehicles; a conductor to electrically connect the contactors with DC input; 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. The DC EVSE may also include, external to the secure enclosure, a controller that is coupled with the circuits to control the opening and closing of the set of contactors.
