Abstract
A method for determining the buffering effect of the battery () for providing a voltage (U) for a power supply system (), in particular for a vehicle, is provided in order to identify serviceability of a battery as easily and reliably as possible, in which method any voltage change and any current change are detected cyclically, the dynamic internal resistance of the battery is determined on the basis of the quotient of the voltage change and the current change, the specific dynamic internal resistance is monitored for exceeding an extreme value which can be predetermined, and a statement of the buffering effect of the battery is made and is output. In this case, the buffering effect of the battery is better, the smaller the quotient of the voltage change and current change.
