Bidirectional energy transfer system and method utilizing a cordset

A bidirectional energy transfer system, comprising:

• a cordset that transfers power from a device to at least one battery array within a traction battery of an electrified vehicle when the cordset is operating under a first condition, and that transfers power from the at least one battery array to the device when the cordset is operating under a second condition,
• wherein, under the second condition, power received by the cordset from the at least one battery array has been converted from DC to AC by an inverter of the electrified vehicle;
• a plurality of relays of the cordset, the plurality of relays powered by power from the at least one battery array when the cordset is operating under the second condition;
• and
• a plurality of switches of the cordset, the plurality of switches powered by power from the at least one battery array when the cordset is operating under the second condition.

A bidirectional energy transfer method, comprising:

• operating a cordset under a first operating condition where the cordset receives power from a device and transfers the power to an electrified vehicle to charge at least one battery array within a traction battery of the electrified vehicle;
• operating the cordset under a second operating condition where the cordset receives power from the at least one battery array and transfers the power to the device, the power received by the cordset is AC power that is converted from DC by an inverter of an electrified vehicle;
• using power from the at least one battery array to power a plurality of relays of the cordset when the cordset is operating under the second operating condition;
• and
• using power from the at least one battery array to power a plurality of switches of the cordset when the cordset is operating under the second operating condition.
