Reliability Centred Planning, Mapping & Analysis of Electronics and Electrical Systems in Electric Mobility

Reliability of a product is very critical aspect for a new product to create a success story in present age. This paper is focused on automobile industry especially in electric mobility domain. IC engines are in this market from last 100+ years and too much improvement work has been done in IC engine domain. First car powered by IC engine was made in 1885 by Karl Benzand from 1885 to present the IC engine mobility have undergone numerous process improvements and established them as a reliable mode of mobility. There are many process models available online which can be used to improve the reliability of IC engine powered mobility. In case of electric mobility there is major integration of three different domains electrical, mechanical & electronics. Electrical mobility is just 2 decade old and major developments happened in this space in last one decade. The major challenge in electric mobility domain is the change content, in IC engine mobility the if we compare one car model to another car model the change content is <25% but in case of electric mobility vs IC engine mobility the change content is >75%. Now the challenge is to manage & effectively synchronize this high change content moreover to establish the product reliability as equal or better than existing IC engine powered mobility. There are various reliability improvement models are available in electrical, mechanical and electronics domain. There is a need to integrate the reliability improvement models of electrical and electronics domain with automobile (mechanical domain) keeping automobile reliability improvement models as masters of process so that to establish product reliability in electric mobility. The overall aim of this dissertation work is to develop a reliability engineering model to establish the reliability and dependability of electric mobility in future.
