Abstract
An off-board load power management system for an electrified vehicle is provided. The system may include a DC-to-AC inverter for providing power to auxiliary loads. Using a manual selector, an operator may select an amount of power to be allocated for inverter use at all time during vehicle operation. A controller may guarantee the selected amount of power is available for inverter use and control a generator accordingly. The controller may manage the distribution of power from a battery and/or generator to the powertrain and other vehicle accessories to ensure the selected amount for the inverter always remains available.
Claims20
A system for an electrified vehicle comprising:
- an inverter;
- a battery that receives energy from a generator and provides power to the inverter;
- a manual power selector that receives an operator input of a minimum numerical amount of power to allocate to the inverter for off-board loads not associated with propulsion of the vehicle;
- and
- a controller configured to control output of the generator based on the operator input and allocates at least the minimum numerical amount of power to the inverter.
A vehicle comprising:
- an inverter that converts DC energy from a high-voltage bus to AC energy for off-board loads not associated with vehicle operation;
- a manual power selector that receives an operator input indicative of a minimum numerical amount of power to allocate to the inverter for the off-board loads;
- and
- a generator that provides energy to the high-voltage bus based in part on the numerical amount.
A method comprising:
- receiving, through an interface, an operator input indicative of a minimum numerical amount of power to allocate to an inverter for off-board loads not associated with propulsion of the vehicle;
- controlling output of a generator in an electrified vehicle based on the minimum numerical amount;
- and
- allocating at least the minimum numerical amount to the inverter during operation of the vehicle.
