Development of hybrid and electrical cars encounters integration of a key enabler. Integration, at the largest meaning, delivers a system that is greater than the sum of its parts. New technologies are considered and tight combinations of existing technologies are experimented. Evaluating the possibilities of failure mechanism, investigation reliability and the way for active safety monitoring are impacted as studies have to be revisited and new approaches are to be delivered. In this context,Ampere-lab is carrying several activities that are summarized here. Activities on high-temperature have led to analyses of failure mechanisms and possibility of reliability evaluation on wide-band-gap semiconductors. Passive devices receive new efforts as temperature ranges are pushed. Storage components become key devices with the idea to bring their lifetime to the limit. Prognostics and diagnostics are renewed issues.
