Abstract
A vehicle includes a power plant, an electrical port, and a controller. The controller is configured to transmit a signal to the inverter via a conductor of the port indicating a maximum power available. The signal may be transmitted responsive to indication of an off-board inverter being plugged into the port. The controller may be further configured to complete a circuit between the power plant and the inverter. The circuit may be completed responsive to an expected predefined reduction in peak voltage of the signal caused by the inverter.
Claims17
A vehicle comprising:
- a power plant;
- an electrical port;
- and
- a controller configured to,
- responsive to indication of an off-board inverter being plugged into the port, transmit a signal to the inverter via a conductor of the port indicating a maximum power available,
- responsive to an expected predefined reduction in peak voltage of the signal caused by the inverter, complete a circuit between the power plant and the inverter, and
- limit power supplied to the inverter to less than the maximum power available based on a demand of the inverter having a variability greater than a variability threshold such that as the variability increases, the power supplied decreases.

A method comprising:
- by a controller,
- responsive to an inverter located off-board a vehicle being plugged into an electrical port of the vehicle, transmitting a signal to the inverter indicating a maximum power available;
- responsive to an expected predefined reduction in peak voltage of the signal caused by the inverter, completing a circuit between a power plant of the vehicle and the inverter;
- and
- responsive to a demand of the inverter having a variability greater than a variability threshold, operating an engine to supply constant output.
