  • System for a drive energy store of a hybrid or electric vehicle, and method for charging a drive energy store of a hybrid or electric vehicle
    Patent number: 11981217
    Abstract: A system for a drive energy store of a hybrid or electric vehicle is provided. The system includes a receiver which is designed to receive state information of the drive energy store, the state information specifying whether a defect is present or imminent in the drive energy store; and a charging controller, which is designed to adjust a maximum charging voltage and/or a maximum state of charge for a charging process of the drive energy store by a recovery mechanism and/or a load point shift and/or an external charging station to a reduced value if the state information indicates that the defect is imminent.
    Type: Grant
    Filed: October 2, 2019
    Date of Patent: May 14, 2024
    Assignee: Bayerische Motoren Werke Aktiengesellschaft
    Inventors: Armin Friegel, Robert Lustig, Bernhard Sessner, Hubertus Welsch
  • Energy storage device and device and method for determining a capacitance of an energy storage device
    Patent number: 11162992
    Abstract: An energy storage device has a plurality of storage cells. In this case, each storage cell is designed to be connected in an offline operation and separately from the remaining storage cells to a device for determining the capacitance of the energy storage device.
    Type: Grant
