  • Device and method for balancing an energy storage module
    Patent number: 11411411
    Abstract: A device balances an energy storage module having multiple energy storage cells connected in series.
    Type: Grant
    Filed: November 25, 2019
    Date of Patent: August 9, 2022
    Assignee: Bayerische Motoren Werke Aktiengesellschaft
    Inventors: Tobias Hollweg, Johannes Kurtz
  • Method for operating an energy storage system and energy storage system
    Patent number: 11264809
    Abstract: A method for operating an energy storage system, which includes at least one energy store with a plurality of cells and is designed to supply an electric drive system of a vehicle is provided. The method includes identifying a reference cell from among the cells, and carrying out a first symmetrization procedure for the cells at a first point in time, at which the reference cell has a first reference charge state.
    Type: Grant

    Date of Patent: March 1, 2022
    Assignee: Bayerische Motoren Werke Aktiengesellschaft
    Inventor: Tobias Hollweg
  • Method for testing a balanced circuit
    Patent number: 10770906
    Abstract: A method tests a balancing circuit for a battery having a plurality of battery cells. The method detects first voltage states of the battery cells by way of a control unit; activates the balancing circuit with the aim of achieving a voltage equalization of at least two of the battery cells; detects second voltage states of the battery cells by way of the control unit; and determines a functional capability of the balancing circuit based on the first voltage states and the second voltage states of the battery cells by way of the control unit.
