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.

Embodiments discussed herein refer to electric vehicle charging ports having integrated contactless communication units (CCUs). The electric vehicle charging ports include male and female connector assemblies that can be coupled together in a manner that enables consistent and reliable operation of contactless communications and power transfer. The connector integrates power and alignment such that when two connector assemblies are coupled together, power connections are made in combination with establishing contactless communications links between counterpart CCUs in both connector assemblies. The fixed alignment of the connector assemblies ensures that contactless communication channels, spanning between the connector assemblies, are aligned to enable consistent and reliable operation of contactless communications. The CCUs, which conduct contactless communications, may be integrated in the connector assemblies at fixed positions that enable CCUs of one connector assembly to be aligned with CCUs of another connector assembly when they are coupled together.
