Methods and apparatuses for voltage dip stabilization in a motor vehicle are described herein. The apparatus of one embodiment includes a first connection for connecting the apparatus to an energy source, in particular to a vehicle battery and a second connection for connecting the apparatus to a starting apparatus of a motor vehicle. The apparatus also includes a current-limiting module for limiting a starter current, a control unit for driving the current-limiting module, and at least one starting process detector, which is connected to the control unit, for identifying a starting process. The control unit, on the basis of a starting process signal from the starting process detector, prompts the current-limiting module to carry out a starter current-limiting measure.
