| 20220140413 | REVERSIBLE THERMAL MANAGEMENT SYSTEM AND METHOD FOR A WORK MACHINE - A reversible thermal management system and method for a work machine is disclosed. The system comprises a prime mover, a battery, a first circuit, and a second circuit. The battery supplies at least a portion of power of the prime mover. The first circuit circulates a glycol adapted to exchange thermal energy with one or more of an electronic component, a transmission circuit, a hydraulic circuit and the battery. The second circuit circulates a refrigerant. The second circuit, which is thermally coupled to the first circuit by at least one heat exchanger, is adapted to exchange thermal energy with air. | 05-05-2022 |
| 20220140419 | BATTERY STATE INDICATOR BASED ON RECOMBINATION DEVICE FEEDBACK - An aqueous battery system includes an electrode assembly, a recombination device, and a controller. The recombination device has a catalyst that combines hydrogen and oxygen produced by the electrode assembly to form water and generate heat via exothermic reaction. The controller, responsive to a detected temperature or change in temperature associated with the recombination device due to the heat, changes power supplied to the electrode assembly. | 05-05-2022 |
