Abstract

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.
