The environmental impacts of electric vehicles (EVs) partially depend on the parameters of their site of operation. Variations of average driving patterns in different geographic locations and the use of heating and cooling due to local climate conditions have an impact on the energy consumption of EVs. In combination with the regional electricity mix these factors influence the environmental impact of EVs. Hence, these influencing factors must be included in an ecological assessment. The Life Cycle Assessment (LCA) method is used for the quantitative ecological assessment. An LCA can e.g. serve as a decisions support tool in vehicle engineering. This paper proposes a framework to consider influencing factors for the ecological assessment of EVs. A case study is used to demonstrate the capability of the framework.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
