  • Single disconnect switch for multiple battery systems
    Patent number: 12054055
    Abstract: An electrical system for providing electrical power to an electric machine, where the electrical system includes a single point disconnect switch for multiple battery systems. The single point disconnect switch may be remotely mounted. In some examples, operation of the disconnect switch disconnects a first battery system, e.g., a 12 VDC nominal battery system, which, in turn, causes a disconnection of a second battery system, e.g., a 48 VDC nominal battery system.
    Type: Grant
    Filed: September 30, 2022
    Date of Patent: August 6, 2024
    Assignee: Caterpillar Inc.
    Inventors: Ryan P. McEnaney, Kareem Gad, Omar Baba, James K. McCloskey

  • Method and systems for controlling electrically-powered hydraulic circuits
    Patent number: 11946225
    Abstract: One embodiment of a hydraulic system for a machine has a first hydraulic circuit including a first pump coupled to a first hydraulic actuator configured to move a first implement of the machine. A second hydraulic circuit includes a second pump coupled to a second hydraulic actuator configured to move a second implement. An electric motor mechanically couples to the first pump and to the second pump. An operator interface receives input from an operator requesting movement of the first and second implements. A controller communicatively coupled to the electric motor and to the operator interface determines, based on the requested movement of the first and second implements respectively, first and second flow allocations respectively for the first and second pumps and determines respective target displacements for the first and second pumps.
