Diagnostic Receptacle For Electric Vehicle Supply Equipment
First Claim
1. A method comprising:
- detecting, by electric vehicle supply equipment, whether a connector, configured to provide electric power to an electric vehicle, is electrically connected to a receptacle of the electric vehicle supply equipment; and
obtaining electrical measurements, by the electric vehicle supply equipment, at an end of one or more conductors accessible via the connector;
determining a status of the one or more conductors based on the obtained electrical measurements; and
indicating whether the electric vehicle supply equipment is available for use.

Abstract
Systems, methods, apparatuses, and computer-readable media provide electric supply equipment 200 configured to perform diagnostics. The electric supply equipment 200 may include a receptacle 210 for forming a closed circuit loop. The electric supply equipment 200 includes a connector 203 for charging devices, such as electric vehicles 101. The connector 203 may include one or more conductors, some of which may be wrapped with insulation. When the connector 103, 203 is not used for charging, the connector 203 may be connected to a receptacle 210 of the electric supply equipment 200. Thus, the electric supply equipment 200, via the receptacle 210, may form a closed loop circuit with the conductors. Further, the electric supply equipment 200 may include a diagnostic unit 250 for performing diagnostic tests on the conductors. In particular, the diagnostic unit 250 may access ends of the conductors via the receptacle 210.
