Abstract

A power allocation method includes monitoring at least one first device that can be recharged by a vehicle, monitoring at least one second device that can be electrically powered by the vehicle, and adjusting a charging of the at least one first device based on an operation of the at least one second device.

First claim

What is claimed is:

1 . A method, comprising:
monitoring at least one first device that can be recharged by a vehicle, the at least one first device external to the vehicle and electrically coupled to the vehicle through a first electrical outlet of the vehicle; monitoring at least one second device that can be electrically powered by the vehicle, the at least one second device external to the vehicle and electrically coupled to the vehicle through a second electrical outlet of the vehicle that is different than the first outlet; and adjusting a charging of the at least one first device based on an operation of the at least one second device.

2 . The method of claim 1 , wherein adjusting the charging of the at least one first device based on a starting of the at least one second device.

3 . The method of claim 2 , wherein adjusting the charging includes reducing an amount of power provided to the at least one first device.

4 . The method of claim 2 , wherein adjusting the charging includes stopping a charging of the at least one first device prior to a starting of the at least one second device.

5 . The method of claim 4 , wherein stopping the charging includes shutting off the first electrical outlet, the at least one first device electrically coupled to the vehicle via the first electrical outlet.

6 . The method of claim 1 , wherein the at least one second device is a pump.

7 . The method of claim 1 , wherein the at least one second device is a compressor.

8 . The method of claim 1 , further comprising adjusting the charging of the at least one first device based on a state of charge of the at least one first device.

9 . The method of claim 1 , further comprising providing electrical power to the at least one second device through the second electrical outlet, the vehicle configured to transition the second electrical outlet between a powered state where the second electrical outlet can be used to power the at least one second device and an unpowered state where the second electrical outlet cannot provide power to the at least one second device.

10 . The method of claim 9 , further comprising transitioning the at least one second device from the unpowered state to the powered state after adjusting the charging.

11 . The method of claim 1 , further comprising adjusting the charging by charging the at least one device using power that is provided to the vehicle from an external source rather than power from a traction battery of the vehicle.

12 . The method of claim 1 , further comprising requesting an additional power source in response to a projected usage being greater than what the vehicle can provide.

13 . A method, comprising:
charging at least one first device from a vehicle when the at least one first device is electrically coupled to the vehicle through at least one first electrical outlet of the vehicle, the at least one first device external to the vehicle; receiving a request for the vehicle to power at least one second device from the vehicle when the at least one second device is electrically coupled to the vehicle through at least one second electrical outlet of the vehicle, the at least one second electrical outlet different than the at least one first electrical outlet, the at least one second device external to the vehicle; and adjusting the charging in response to the request.

14 . The method of claim 13 , wherein adjusting the charging includes stopping the charging.

15 . The method of claim 13 , wherein adjusting the charging includes stopping the charging until the at least one second device has started, and then restarting the charging while the at least one second device is running.

16 . The method of claim 13 , wherein the at least one second device is a compressor that is driven by a power take off of the vehicle.

17 . The method of claim 13 , wherein the at least one second device is a pump.

18 . The method of claim 13 , wherein the at least one second device is a winch.

19 . A system for a vehicle, comprising:
an electrified vehicle having a traction battery; at least one first device that is external to the electrified vehicle and is configured to be charged by the vehicle through at least one first electrical outlet of the vehicle; at least one second device that is external to the electrified vehicle and is configured to operate while being electrically powered by the vehicle through at least one second electrical outlet of the vehicle that is different that the first electrical outlet; and a control module configured to adjust a charging of the at least one first device in response to a need to operate the at least one second device.

20 . The system of claim 19 , wherein the at least one second device comprises an electrically powered motor.
