Status and future perspectives of reliability assessment for electric vehicles

Highlights: • EVs' reliability assessment overview. • Role of the reliability and safety in the present and future EVs applications. • Failure analysis in electrical components of EVs. -- Abstract: Using clean energy sources has contributed to various industries, especially the automotive industry. In this regard, large companies have taken a significant step in the field of renewable energy by introducing Electric Vehicles (EVs). One of the main challenges in the EVs area is evaluating the reliability and safety of these vehicles. Thus, the concept of the reliability and safety of EV's components is considered a significant issue. In general, reliability and safety assessment of important electrical components of EVs, i.e. i) the battery pack, ii) power electronic converters, and iii) the electric motor, plays a significant role in the lifetime performance of EVs' electrical system. This paper presents a comprehensive review of the reliability of EVs' components from different points of view. Also, the challenges and future perspective of EVs relating to the reliability and safety, which need to be considered have been investigated.
