Claim of US Patent No. 9,511,676

1. A system comprising:
an electrified vehicle (EV); and
a stand-alone self-contained EV energy transfer apparatus (EVETA) releasably coupled to said EV, comprising an electronics
assembly encased at a hand-portable housing, said housing configured to receive an external AC load, said EVETA configured
to transfer energy from an energy storage device (ESD) at said EV to an electric load releasably coupled to said EVETA, said
electric load external to said EV and said EVETA, said EVETA comprising a cable affixed to and extending from said housing
at a first end including at its opposing end a connector configured for releasably electrically coupling a charge inlet at
said EV, said charge inlet compatible with electric vehicle service equipment (EVSE) charging apparatus, said cable configured
to provide energy from said EV ESD to said EVETA, a DC/AC inverter configured to receive DC input from said EV ESD via said
cable, said cable directly coupled to a pre-charge circuit directly coupled to said DC/AC inverter, and provide AC output
to an AC outlet at said housing, a controllable DC/DC converter directly coupled to said pre-charge circuit and configured
to provide a DC output, a control module configured to authorize said energy transfer, a human machine interface (HMI), and
a fault detection module (FDM) configured to detect an isolation fault.
