Claims20
An outlet power architecture for a vehicle, the outlet power architecture comprising:
- a power source including a power load including a direct current (DC) load;
- a direct current to alternating current (DC-AC) converter coupled to the power source, the DC-AC converter including a plurality of switches and a first capacitor and a second capacitor operably coupled to the plurality of switches;
- a DC to DC (DC-DC) converter coupled to the power source;
- and
- a power outlet operably coupled to the DC-AC converter, the power outlet configured to execute at least one of a first DC power conversion, a second DC power conversion, and a third DC power conversion, the first DC power conversion including a direct DC output, the second DC power conversion including a shared DC output, and the third DC power conversion including the DC-DC converter.
An outlet power architecture for a vehicle, the outlet power architecture comprising:
- an engine generator;
- an inverter coupled to the engine generator;
- a converter coupled to the engine generator via the inverter, the converter including a plurality of switches, at least one capacitor operably coupled to the plurality of switches, and a direct current to direct current (DC-DC) converter;
- and
- a power outlet operably coupled to one of the converter and the inverter, the power outlet configured to identify a DC load and generate at least one of a first DC power conversion, a second DC power conversion, and a third DC power conversion, the first DC power conversion including a DC output from one of the converter and the inverter, the second DC power conversion including a shared DC output, and the third DC power conversion including the DC-DC converter.
A method of generating power using an outlet power architecture for a hybrid vehicle, the method including:
- activating a vehicle to device mode of the outlet power architecture;
- disconnecting, via the outlet power architecture, a battery of a vehicle from an in-vehicle module;
- determining, via the outlet power architecture, a status of an engine generator;
- executing, via the outlet power architecture, an inverter based on the status of the engine generator, the inverter including a first configuration and a second configuration;
- identifying, via the outlet power architecture, a power load including at least one of an alternating current (AC) load and a direct current (DC) load;
- identifying, if present, the DC load;
- executing at least one of a first DC power conversion, a second DC power conversion, and a third DC power conversion, the first DC power conversion including a direct DC output, the second DC power conversion including a shared DC output, and the third DC power conversion including a DC to DC (DC-DC) converter;
- regulating, based on the identified power load, the engine generator at a load speed;
- and
- generating, based on the identified power load and the regulated load speed, power.
