Abstract
Lifetime heterogeneity results from differing lifetimes of subsystems and components (entities) within a system and is a key criteria to evaluate life cycle options, like upgrading or reuse, for more sustainable products. In early design stages of products for new use cases only limited information for lifetime prognosis are available. This paper proposes a concept to forecast the lifetime of products without experimental data. For purpose a systematic review is conducted to analyze degradation models of Li-ion batteries and electric motors. By analyzing and comparing similarities regarding influencing factors and their impact, fundamentals for degradation modelling are derived. Based on these findings a procedure for lifetime prediction in early design stages for emerging products, like Li-ion batteries and electric motors, are derived."
