Abstract: 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.

Abstract: A motor vehicle is proposed having a ride level control device with a pneumatic lift system , with a ride level control unit, to which the operating parameters of the motor vehicle which are detected by sensors are fed. The ride level control unit is active if the ignition of the motor vehicle is switched on. Furthermore, when various conditions are met, the ride level control unit outputs a signal to the lift system so that the motor vehicle is raised. A bidirectional connection is present between the ride level control unit and the lift system in order to transmit feedback from the lift system to the ride level control unit.
