Method for determining consumed or remaining service life of e.g. power supply, involves determining component interval service life by multiplying aging acceleration factor with operation interval duration

摘要

The method involves determining aging acceleration factor for one component (4). The component interval service life is determined by multiplying aging acceleration factor with operation interval duration. The current consumed or remaining component service life of the component is determined by the component interval service life to a previously determined consumed component life is added or a pre-determined remaining component life or a predetermined component life is subtracted. An independent claim is included for device for determining consumed or remaining service life of electric appliance.
