Abstract
The disclosure relates to a method for determining the aging of an electronic interrupter element which is configured to open and close a power circuit. The method according to the disclosure comprises the following steps: a) initializing an aging counter NWear, b) determining the amount I of a current which flows through the electronic interrupter element upon opening the power circuit, c) determining a current-dependent aging value Nwear (I) from the amount I of the current, d) refreshing the aging counter NWear using the current-dependent aging value Nwear (I). The disclosure further relates to a computer program and to an apparatus for determining the aging of an electronic interrupter element and to a battery management system which are in particular configured to carry out the method.
