  • Power system for a machine
    Patent number: 12006658
    Abstract: A power system may include a high-speed flywheel connected to an engine of a machine; a battery; a motor-generator unit (MGU) connected to the engine and the battery; and a turbocharger connected to the engine. One or more of the high-speed flywheel, the battery and the MGU, or the turbocharger may be configured to provide supplemental power to power provided by the engine to operate the machine, or provide replacement power when no power is provided by the engine to operate the machine.
    Type: Grant
    Filed: April 9, 2021
    Date of Patent: June 11, 2024
    Assignee: Caterpillar Inc.
    Inventors: Chad Koci, Jay R. Steffen, Fang Guo, Richard W. Kruiswyk, Gaurav Vasudeva, Robert Michael McDavid, Timothy Adam Bazyn
  • Hybrid power system control and operating strategy based on power system state vector calculation
    Patent number: 11728658
    Abstract: Controlling a hybrid power system includes calculating a power system state vector based on energy demand and a stored data array including a matrix defined by a power system hardware configuration. The control further includes producing a power request based on the power system state vector, and varying a flow of energy amongst energy devices using drive linkages in the hybrid power system based on the power request. Related apparatus, control logic and controller structure is disclosed.
