Abstract:
A cell balancing system includes sensing circuitry configured to sense a cell voltage of each of a plurality of cells of a battery. Cell balancing circuitry is configured to balance each of the plurality of cells in response to a respective cell balancing command for each of the plurality of cells. A comparison circuit configured to compare the sensed cell voltages for each of the plurality of cells to an adaptive threshold voltage. The comparison circuit generates a respective cell state for each of the plurality of cells to indicate a state of the respective cell voltage for each of the plurality of cells relative to the adaptive threshold voltage. A controller is configured to set the respective cell balancing command for each of the plurality of cells and to adjust the adaptive threshold voltage based on an evaluation of the cell states for the plurality of cells.
