Method and Apparatus for Determining the Aging of an Electronic Interrupter Element, in Particular of a Power Contactor

摘要

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.

主权项

1. A method for determining an aging of an electronic interruption element that is configured to open and close a circuit, the method comprising:
a) initializing an aging counter Nwear; b) determining an absolute value I of a current that flows when the circuit is opened by the electronic interruption element; c) determining an aging value Nwear(I) that is dependent on the absolute value I of the current; and d) refreshing the aging counter Nwear using the aging value Nwear(I).
