Abstract
Responsive to data being indicative of conditions that will decrease a life of a battery to the extent the life expectancy will be less than a target value with a confidence that exceeds a first threshold, a processor may generate an alert or mitigation recommendations. Responsive to data being indicative of the cause of conditions that result in the life expectancy to be less than a target value with a confidence that exceeds a second threshold, the processor may implement a control strategy or set of control strategies to benefit the life expectancy of the battery.
Claims20
A control arrangement for a vehicle comprising:
- a controller programmed to, while the vehicle is parked and
- responsive to data being indicative of key-off loads exceeding a load threshold with a confidence that exceeds a first confidence threshold, deactivate at least one electronic control unit of the vehicle, and
- responsive to data being indicative of key-off loads exceeding the load threshold with a confidence that exceeds a second confidence threshold greater than the first confidence threshold, prevent user activation of an entertainment system of the vehicle.
A method for a vehicle, comprising:
- after receiving data indicating key-on loads exceed a load threshold with a confidence that exceeds a first confidence threshold, preventing power flow to at least one auxiliary power outlet of the vehicle;
- and
- after receiving data indicating key-on loads exceed a load threshold with a confidence that exceeds a second confidence threshold greater than the first confidence threshold, preventing power flow to snowplow equipment of the vehicle.
A vehicle comprising:
- a battery;
- and
- a controller programmed to
- responsive to data being indicative of key-off loads exceeding a load threshold with a confidence that exceeds a first confidence threshold, deactivate at least one electronic control unit of the vehicle, and
- responsive to data being indicative of key-on loads exceeding another load threshold with a confidence that exceeds a second confidence threshold, dim interior lighting of the vehicle.
