Abstract
A capacity estimator determines a total maximum allowable power storage capacity for a work vehicle. A timer times the operating time of the work vehicle in an electrically propelled mode. A load manager, a driver or both decrease the available power to at least one of a drive motor of the work vehicle and an ancillary load over the operating time to conserve the available power stored for operating at least one critical work vehicle.
Claims24
A method of controlling power consumption of a work vehicle, the method comprising:
- determining a total maximum allowable power draw for a work vehicle;
- classifying power loads of the work vehicle into critical power loads and non-critical power loads;
- timing the operating time of the work vehicle in an electrically propelled mode;
- and
- allocating the available power between the critical power loads and non-critical power loads according to the operating time.
A method of controlling power consumption of a work vehicle, the method comprising:
- determining a total maximum allowable power storage capacity for a work vehicle;
- timing the operating time of the work vehicle in an electrically propelled mode;
- and
- decreasing the available power to at least one drive motor of the work vehicle over the operating time to conserve the available power stored for operating at least one critical load of the work vehicle.
A system of controlling power consumption of a work vehicle, the system comprising:
- a capacity estimator for determining a total maximum allowable power draw for a work vehicle;
- a classifier for classifying power loads of the work vehicle into critical power loads and non-critical power loads;
- a timer for timing the operating time of the work vehicle in an electrically propelled mode;
- and
- a controller for allocating the available power between at least one critical power load and at least one non-critical power load according to the operating time.
