  • System and method for detecting failures in a battery management system for a vehicle battery
    Patent number: 11422193
    Abstract: The disclosed subject matter relates to a method and system for detecting failures in a cell measuring circuit for a vehicle battery including a plurality of battery cells. First the method includes determining a cell voltage of each of the plurality of cells by the respective cell measuring circuit. Next, the method includes performing cell balancing to balance a cell voltage for the plurality of cells and the cell balancing times are compared to determine if there are deviating cell balancing times, and if there is an identifiable pattern in the cell balancing times which can provide an indication of a failure in any of the cell measuring circuits.
