A battery management apparatus for a motor vehicle battery, wherein the battery includes a plurality of series-connected battery cells, wherein the apparatus includes a device for determining a cell voltage for each battery cell in the battery, wherein the apparatus compares the determined cell voltages of the battery cells with one another and processes them such that, if the cell voltage of at least one battery cell is greater than a first limit value and, furthermore, if the cell voltage of at least one battery cell differs from the cell voltage of the or each other battery cell by more than a defined second limit value, the apparatus uses the lowest cell voltage of the battery cells as the reference voltage, and it discharges the or each other battery cell with a higher cell voltage in order to balance the voltage between the battery cells at the reference voltage. |
