Abstract

This objective is achieved according to the present invention in that in a method for determining the deterioration of a battery, the charge and discharge cycles of the battery are measured by number and depth of the charge/discharge. For each of the charge and discharge cycles, a characteristic deterioration value is determined on the basis of a deterioration curve that is characteristic of the specific battery type. These individual characteristic deterioration values are then summed up to obtain the deterioration of the battery.
