Abstract
Electric mobility is on the verge of becoming a mass market. Major automotive OEMs have initiated programs to electrify their product portfolio. This transition poses new challenges and requires new innovative concepts in automotive development processes, especially for battery systems as the key component within electric powertrains. Battery system costs account for up to 40% of the electric vehicle’s total costs. Additionally, development cycles of battery systems for automotive applications are characterized by long development periods. Hence, the initiatives to advance electrification result in numerous development projects affiliated with significant development expenses. Battery systems can be referred to as mechatronic and electrochemical systems. They require a complex interaction of diverse scientific and engineering disciplines. Fast innovation cycles have effects regarding product requirements and assumptions towards their allocation. Hereby, uncertainties can lead to risks within development projects, especially in terms of time and costs. In current development processes, necessary changes are only dealt with reactively, causing unplanned additional expenses and delays. Thus, there is need for handling potential changes proactively, i.e. managing uncertainties leading to those changes as early as possible. New methods are necessary to identify and handle uncertainties of complex product systems within requirements engineering. An approach towards comprehensive uncertainty management is taken within this publication.
Highlights
Today’s product development projects in the automotive industry are usually characterized by fundamental challenges: volatility, uncertainty, complexity and ambiguity (VUCA) [1]
A cost–benefit-analysis is necessary to get to know the economic impact of an uncertainty, its induced risk to product development and potential measures to handle that uncertainty/risk. This should be focused in further research. As business processes, such as battery system development, gain more uncertainty in general nowadays, there must be ways established to minimize risks, which are a consequence of uncertainty
Uncertainty management can deliver an important aspect in reducing risks in battery systems development
Summary
Today’s product development projects in the automotive industry are usually characterized by fundamental challenges: volatility, uncertainty, complexity and ambiguity (VUCA) [1]. The centre of the VUCA framework is the situation of complexity, which has direct and indirect influence on all other variables and is responsible for an increasing degree of uncertainty. Companies are affected by this uncertainty in various ways [2]. A major driver of uncertainty in the mobility sector is disruptive change. The shift towards electric drive trains opposes major changes. Three main drivers are responsible for the pressure on OEMs regarding development of electric cars
