Abstract

A vehicle includes power outlets configured to receive power from an inverter. The vehicle includes power sources configured to supply power to the inverter and a plurality of electrical systems. A controller is programmed to, responsive to detecting a load connected to one of the power outlets, change a maximum power limit of the electrical systems by an amount associated with the one of the power outlets.

First claim

What is claimed is:

1. A vehicle comprising:
power outlets configured to receive power from an inverter and including receptacles configured to receive a mating electrical plug; and
power sources configured to supply power to the inverter and a plurality of electrical systems; and
a controller programmed to, responsive to detecting a load connected to one of the power outlets, reduce a maximum power limit of the electrical systems by a maximum power associated with the one of the power outlets, wherein the maximum power includes a power provision efficiency factor to compensate for energy conversion efficiency between the power sources and the power outlets.

2. The vehicle of claim 1 wherein the controller is further programmed to, responsive to detecting no loads connected to the power outlets, operate the electrical systems to increase the maximum power limit of the electrical systems.

3. The vehicle of claim 1 wherein the controller is further programmed to, responsive to a total decrease in the maximum power limit exceeding a maximum outlet power allocation, limit the total decrease in the maximum power limit to be the maximum outlet power allocation.

4. The vehicle of claim 1 wherein the controller is further programmed to process historical power consumption data for each of the power outlets and output an estimated future power consumption based on the historical power consumption data.

5. The vehicle of claim 4 wherein the controller is further programmed to operate the electrical systems to change the maximum power limit of the electrical systems according to the estimated future power consumption.

6. The vehicle of claim 4 wherein the controller is further programmed to generate the estimated future power consumption as a maximum power consumption value derived from the historical power consumption data over a predetermined time interval.

7. The vehicle of claim 4 wherein the controller is further programmed to generate the estimated future power consumption as an average power consumption value derived from the historical power consumption data over a predetermined interval.

8. A vehicle comprising:
power outlets configured to receive power from an inverter; and
power sources configured to supply power to the inverter and a plurality of electrical systems; and
a controller programmed to, responsive to detecting a load connected to one of the power outlets, reduce a maximum power limit of the electrical systems by a maximum power associated with the one of the power outlets wherein the maximum power includes a power provision efficiency factor to compensate for energy conversion efficiency between the power sources and the power outlets.

9. The vehicle of claim 8 wherein the power provision efficiency factor varies with temperature and current.

10. A vehicle comprising:
power outlets configured to receive power provided by an inverter;
power sources configured to supply power to the inverter and a plurality of electrical systems; and
a controller programmed to, responsive to detecting a load connected to one of the power outlets, decrease a maximum power limit of the electrical systems by a predicted power consumption associated with the one of the power outlets, wherein the controller is further programmed to include a power provision efficiency factor in the predicted power consumption.

11. The vehicle of claim 10 wherein the predicted power consumption is based on historical power consumption data associated with the one of the power outlets.

12. The vehicle of claim 11 wherein the predicted power consumption is a maximum power consumption value derived from the historical power consumption data over a predetermined time interval.

13. The vehicle of claim 11 wherein the predicted power consumption is an average power consumption value derived from the historical power consumption data over a predetermined interval.

14. The vehicle of claim 10 wherein the controller is further programmed to, responsive to detecting a change of status to the one of the power outlets, decrease the maximum power limit of the electrical systems according to a maximum power associated with the one of the power outlets.
