Priority based power management system and method for an electric vehicle
First Claim
1. A method implemented by a control module coupled to an electric motor and an internal combustion engine of a vehicle to provide priority based power management of off-board devices being power by the vehicle, comprising:
- determining, via the control module, an operating mode of the vehicle, the operating mode being an electric operating mode or a fossil fuel operating mode;
determining, via the control module, a current state of charge (SOC) of a battery pack of the vehicle;
supplying power at a maximum load of each of the off board devices when the current SOC of the battery pack is above a predetermined threshold value when the vehicle is operating in the fossil fuel operating mode;
applying, via the control module, at least one priority to each of the off-board devices when the vehicle is operating in the electric operating mode;
when the current SOC of the battery pack is above the predetermined threshold value and the vehicle is operating in the electric operating mode, powering the off-board devices based on the priority of the off-board devices; and
when the current SOC of the battery pack falls below the predetermined threshold value and the vehicle is operating in the electric operating mode, removing power from individual off-board devices based on the priority of the off-board devices until the current SOC of the battery pack rises above the predetermined threshold value.

Abstract
A method to provide priority based power management of off-board devices being power by a vehicle comprising: determining an operating mode of the vehicle, the operating mode being an electric operating mode or a fossil fuel operating mode; determining a current state of charge (SOC) of a battery pack of the vehicle; supplying power to the off-board devices when the current SOC of the battery pack is above a minimum threshold value when the vehicle is operating in the fossil fuel operating mode; prioritizing the off-board devices when the vehicle is operating in the electric operating mode; and powering the off-board devices based on a prioritization level of the off-board devices and the current SOC of the battery pack when the vehicle is operating in the electric operating mode.
