Abstract
A system and method for controlling the electrical power consumption of selected consumers of an electric vehicle limits power to consumers in dependence upon the prevailing charge state of a battery that is provided for driving the vehicle. The electric power consumption of high current consumers is adjusted to use an available residual amount of energy in an efficient manner. Consumers may be selected and corresponding power limits or reduction factors for the consumers and associated battery states of charge via a vehicle graphical user interface.
Claims20
A method for controlling an electrified vehicle, comprising:
- by a vehicle controller:
- limiting electric power consumption of selected power consumers of the vehicle in dependence upon a traction battery state of charge (SOC), the power consumers selected via a graphical user interface communicating with the controller, the graphical user interface allowing a user to specify a relationship between the battery SOC and the limiting of electric power for each selected power consumer.
An electrified vehicle comprising:
- a traction battery;
- electric consumers powered by the traction battery;
- a graphical user interface;
- and
- a controller programmed to receive input from the graphical user interface that designates selected ones of the electric consumers and specifies an associated power relationship for each selected electric consumer based on associated traction battery state of charge values, the controller controlling power provided to each of the selected consumers based on the associated relationship.
A method for controlling a vehicle, comprising:
- reducing, by a controller, power provided from a traction battery to a selected electric consumer in response to a traction battery state of charge (SOC) being between first and second thresholds based on first and second power reduction values for the selected electric consumer, the electric consumer, first and second thresholds, and first and second power reduction values specified by input from a vehicle graphical user interface.
